33 Protein-Packed Vegetables Most People Overlook

Most people think protein means chicken breast, eggs, or a powder you mix into a shaker bottle. Vegetables rarely enter the conversation. That’s a gap worth closing, especially if you’re trying to eat more plants, stretch your grocery budget, or just get more out of the produce you’re already buying.

Some of these will surprise you. A few are vegetables you walk past every single week without thinking twice about their protein content. Others are legitimately underrated and deserve a regular spot on your plate.

Protein counts here are approximate per cooked cup unless otherwise noted, based on commonly available nutritional data. Exact figures vary by preparation method and variety.

This list runs from solid to genuinely impressive. By the time you hit #1, you may rethink what belongs in your cart.

33. Zucchini

Zucchini opens the list not because it’s a protein powerhouse but because it’s genuinely underestimated. A cooked cup delivers roughly 2 grams of protein alongside very few calories, making it one of the more efficient vegetables for anyone watching their overall intake.

It absorbs flavors well, cooks fast, and works in everything from stir-fries to pasta substitutes. The protein isn’t the headline, but it adds up across a meal.

At a Glance: Roughly 2g protein per cooked cup. Low calorie, versatile, pairs well with higher-protein vegetables in the same dish.

32. Beets

Beets have a reputation built almost entirely around their color and their sugar content. What gets less attention is that a cooked cup provides around 2 grams of protein, plus a solid dose of folate and manganese.

Roasted beets hold their texture well and work in salads, grain bowls, or alongside other vegetables on this list. The earthy flavor is an acquired taste, but the nutritional profile is worth the effort.

At a Glance: Roughly 2g protein per cooked cup. Also high in folate and natural nitrates, which research suggests may support circulation.

31. Kale

Kale got overhyped for a while, and the backlash made some people dismiss it entirely. Both reactions missed the point. A cooked cup delivers around 2.5 grams of protein along with a nutrient density that’s hard to match in the produce section.

Massaging raw kale with a little oil breaks down the tough cell walls and makes it far more palatable. Cooked, it wilts down considerably, so a cup of cooked kale started as a much larger raw volume.

At a Glance: Roughly 2.5g protein per cooked cup. Also one of the better plant sources of calcium and vitamin K.

30. Cauliflower

Cauliflower gets used as a substitute for almost everything these days, and the protein content is part of why it holds up so well in those roles. A cooked cup comes in around 2 to 3 grams of protein depending on preparation.

Roasted at high heat, cauliflower develops a nutty, almost meaty texture that makes it genuinely satisfying in ways that steamed cauliflower is not. It’s one of the lower-carb vegetables ranked by net carbs, which makes it useful across a wide range of eating patterns.

At a Glance: Roughly 2-3g protein per cooked cup. Very low net carbs. Works as a rice substitute, mash, or roasted side.

29. Swiss Chard

Swiss chard is one of those vegetables that sits in the produce section looking beautiful and getting passed over by most shoppers. A cooked cup provides around 3 grams of protein alongside magnesium, potassium, and vitamins A, C, and K all in one shot.

The stems and leaves cook at different rates, so adding the stems first and the leaves a minute or two later makes a difference. Sauteed with garlic, it’s one of the easier high-nutrient side dishes to pull off on a weeknight.

At a Glance: Roughly 3g protein per cooked cup. One of the most nutrient-dense leafy greens available year-round.

28. Green Peas (Frozen)

Frozen green peas are one of the better protein-to-cost values in the entire freezer aisle. A cooked cup delivers around 8 grams of protein, which is more than most people expect from a vegetable that costs roughly a dollar a pound.

The frozen version is also nutritionally comparable to fresh because peas are frozen quickly after harvest. You’re not sacrificing much by skipping the fresh ones, which are seasonal and more expensive.

At a Glance: Roughly 8g protein per cooked cup. Inexpensive, freezer-stable for months, and one of the better budget protein sources in the produce category.

27. Collard Greens

Collard greens are a staple in Southern cooking for good reason. A cooked cup comes in around 4 grams of protein and packs a substantial amount of calcium alongside it, more than most people realize from a leafy green.

They’re tougher than spinach or kale and benefit from longer cooking, which makes them ideal for braises and slow-cooked dishes where the flavor develops over time. They’re also one of the more affordable greens at most grocery stores.

At a Glance: Roughly 4g protein per cooked cup. High in calcium. Holds up to long cooking better than most leafy greens.

26. Artichoke Hearts

Fresh artichokes are a project. Canned or jarred artichoke hearts are not, and the protein content is the same either way. A cooked cup of artichoke hearts delivers around 4 grams of protein along with a notable amount of fiber.

Artichoke hearts work in pasta dishes, grain bowls, dips, and flatbreads. They’re one of those ingredients that makes a simple dish feel a little more substantial without adding a lot of calories.

At a Glance: Roughly 4g protein per cooked cup. Also one of the higher-fiber vegetables on this list, which supports satiety.

25. Asparagus

Asparagus is one of the more protein-forward vegetables in the spring produce section, delivering around 4 grams per cooked cup. It’s also one of the faster-cooking vegetables, which matters on a weeknight.

Roasting or grilling asparagus rather than steaming it makes a significant difference in texture and flavor. The tips get slightly crisp, the stalks stay tender, and the whole thing takes under fifteen minutes.

At a Glance: Roughly 4g protein per cooked cup. Also a natural source of folate and prebiotic fiber that feeds gut bacteria.

24. Corn

Corn gets dismissed as a starchy vegetable that doesn’t belong in a nutrition conversation, but a cooked cup delivers around 5 grams of protein. That’s more than most people would guess from something they mainly associate with summer cookouts.

The starch is real and so is the sugar, so corn isn’t the right fit for every eating pattern. But as a protein-contributing vegetable it earns its spot, especially when you’re looking at frugal foods that stretch a grocery budget without sacrificing nutrition.

At a Glance: Roughly 5g protein per cooked cup. Higher in carbohydrates than most vegetables on this list. Best paired with lower-starch options.

23. Lima Beans

Lima beans have an image problem. They’re associated with cafeteria food and reluctant childhood eating, which has made a lot of adults overlook a genuinely solid protein source. A cooked cup delivers around 11 to 12 grams of protein.

Prepared well, usually with aromatics and some acid at the end, lima beans are creamy, filling, and satisfying in a way that most vegetables aren’t. The frozen version is easy to find and cooks quickly.

At a Glance: Roughly 11-12g protein per cooked cup. Also high in iron and potassium. Deserves a serious second look from anyone who wrote them off in childhood.

22. Chickpeas

Chickpeas sit right at the edge of the vegetable and legume categories, and they earn their place on this list either way. A cooked cup comes in at around 14 to 15 grams of protein, which puts them in a different tier than most of what’s above them on this countdown.

Roasted chickpeas make a protein-rich snack that holds up in a bag for days. Blended, they’re the base of hummus. Whole, they work in soups, stews, and grain bowls. The versatility alone makes them worth keeping stocked.

At a Glance: Roughly 14-15g protein per cooked cup. One of the more complete amino acid profiles among plant foods.

21. Green Beans

Green beans are one of those side dishes that appear at almost every dinner table without anyone giving them much nutritional credit. A cooked cup delivers around 2 grams of protein, which is modest, but the fiber content and low calorie count make them a solid supporting player in any meal.

They’re also one of the vegetables that holds up well in the freezer without losing much texture, which makes them a reliable option year-round at a reasonable price.

At a Glance: Roughly 2g protein per cooked cup. High fiber, very low calorie. A useful volume food when building a plate that keeps you full.

20. Sweet Potato

Sweet potatoes bring around 4 grams of protein per cooked cup alongside complex carbohydrates, beta-carotene, and potassium. They’re one of the more nutrient-complete single foods in the produce section.

Roasted or baked with the skin on, they hold their nutrients better and the skin itself adds fiber. They’re also one of the foods with impressive shelf life when stored in a cool, dark spot, often lasting several weeks.

At a Glance: Roughly 4g protein per cooked cup. Very high in beta-carotene. One of the most nutritionally complete vegetables available at any price point.

19. Spinach

Spinach gets credit for protein that deserves a closer look. A cooked cup does deliver around 5 grams of protein, which sounds impressive until you factor in bioavailability. Spinach contains oxalic acid, which binds to some of the iron and calcium and limits absorption.

The protein itself is more accessible, but spinach shouldn’t be your primary protein strategy. It works best as a contributor in a larger meal, not a standalone source. Pairing it with vitamin C-rich foods helps the body absorb more of what it offers.

That said, raw spinach in a salad or smoothie adds real nutritional value. It’s one of the everyday foods with surprising health benefits as long as you understand what you’re actually getting from it.

At a Glance: Roughly 5g protein per cooked cup, but bioavailability is reduced by oxalates. Best used as a nutritional contributor, not a primary protein source.

18. Pumpkin Seeds (Pepitas)

Technically a seed from a vegetable, pepitas earn a spot here because they come from the squash family and deliver protein in a way that no other squash product does. A single ounce provides around 9 grams of protein, and a quarter cup easily gets you there.

They work as a topping on salads, soups, and grain bowls. Roasted with a little salt, they’re also one of the better high-protein snacks that doesn’t require any preparation beyond opening a bag.

At a Glance: Roughly 9g protein per ounce. Also high in magnesium and zinc, two minerals many people run short on.

17. Mushrooms

Mushrooms are fungi, not technically vegetables, but they live in the produce section and function like vegetables in cooking, so they belong on this list. A cooked cup of most common varieties delivers around 3 to 4 grams of protein, with some specialty varieties coming in higher.

More relevant than the raw protein number is the way mushrooms behave in a dish. They have a meaty texture when cooked at high heat, they absorb flavors well, and they add umami depth that makes plant-based meals feel more satisfying.

At a Glance: Roughly 3-4g protein per cooked cup. Shiitake and oyster varieties tend to run higher. One of the better meat-texture substitutes in plant-based cooking.

16. Lentils

Lentils are one of the fastest-cooking legumes, requiring no soaking and coming together in around twenty to thirty minutes. A cooked cup delivers around 18 grams of protein, which puts them in territory usually reserved for animal proteins.

Red lentils break down into a thick, creamy texture ideal for soups and dahls. Green and brown lentils hold their shape better and work in salads and grain bowls. They’re also one of the more affordable proteins available at any grocery store.

At a Glance: Roughly 18g protein per cooked cup. Fast to prepare, high in iron and folate, and one of the best protein-per-dollar foods on the market.

15. Black Beans

Black beans are a staple in cuisines across Latin America and the Caribbean for reasons that go beyond flavor. A cooked cup delivers around 15 grams of protein alongside significant fiber and a range of micronutrients.

Canned black beans are one of the most convenient high-protein foods available, requiring only rinsing and heating. They work in tacos, grain bowls, soups, and dips, making them among the most versatile proteins in any pantry.

At a Glance: Roughly 15g protein per cooked cup. Also very high in fiber, which helps regulate blood sugar and supports satiety after meals.

14. Brussels Sprouts

Brussels sprouts have had a complete reputation overhaul in the last decade, and the protein content is part of why they deserved it. A cooked cup delivers around 4 grams of protein, which is high for a brassica vegetable.

The key is high-heat roasting. Boiled Brussels sprouts are sulphurous and soft in all the wrong ways. Roasted at 425 degrees with cut sides down, they caramelize, the outer leaves get crispy, and the flavor becomes nutty and almost sweet.

At a Glance: Roughly 4g protein per cooked cup. High in vitamin C and K. Roasting is the preparation method that actually does them justice.

13. Kidney Beans

Kidney beans are the protein backbone of chili and for good reason. A cooked cup provides around 15 grams of protein with a firm texture that holds up to long cooking without turning to mush.

One note worth knowing: raw or undercooked kidney beans contain a compound that causes digestive distress. Canned kidney beans are fully cooked and safe. If cooking from dry, a full boil for at least ten minutes is needed before simmering.

At a Glance: Roughly 15g protein per cooked cup. High in iron. Canned versions are fully cooked and ready to use after rinsing.

12. Pinto Beans

Pinto beans are one of the most consumed beans in North America and also one of the most protein-dense, delivering around 15 grams per cooked cup. They’re the base of most refried beans and work equally well whole in soups, stews, and burritos.

Cooked from dry with aromatics, pinto beans develop a creamy texture and savory depth that the canned version doesn’t quite match, though the canned version is still a solid option for weeknight cooking.

At a Glance: Roughly 15g protein per cooked cup. Also high in manganese and thiamine. One of the better budget proteins available year-round.

11. Broccoli

Broccoli gets listed on almost every nutrition article, which has made people tune it out. That’s a mistake. A cooked cup delivers around 4 to 5 grams of protein alongside vitamin C, vitamin K, folate, and fiber, in one of the most efficient nutritional packages available at any grocery store.

The protein in broccoli is also more complete than most vegetables, meaning it contains a wider range of the essential amino acids your body needs. It’s not a complete protein on its own, but it contributes more meaningfully than most plant foods at its price point.

At a Glance: Roughly 4-5g protein per cooked cup. More complete amino acid profile than most vegetables. One of the best nutrition-per-dollar foods in the produce section.

10. Navy Beans

Navy beans are small, white, and quiet about their protein content, which runs around 15 grams per cooked cup. They’re the traditional base for baked beans and Senate bean soup, both of which have been feeding people efficiently for a very long time.

They have a mild flavor that absorbs whatever you cook them with, which makes them one of the more flexible beans in the pantry. They also happen to be one of the highest-fiber beans available, which supports both digestion and sustained fullness after eating.

At a Glance: Roughly 15g protein per cooked cup. Among the highest-fiber beans. Mild flavor makes them useful across a wide range of dishes.

9. Adzuki Beans

Adzuki beans are used widely in East Asian cooking, particularly in Japanese and Korean cuisines where they show up in both savory and sweet dishes. A cooked cup delivers around 17 grams of protein, which puts them near the top of the legume category.

They’re smaller and cook faster than most beans, and their slightly sweet, nutty flavor works well in grain bowls and rice dishes. They’re one of the more overlooked protein vegetables simply because they haven’t crossed into mainstream Western cooking in a significant way yet.

At a Glance: Roughly 17g protein per cooked cup. Also high in folate and potassium. Worth seeking out at Asian grocery stores where they’re typically less expensive.

8. Fava Beans

Fava beans are labor-intensive fresh but much easier from frozen or canned, and the protein payoff is real: around 13 grams per cooked cup. They have a buttery texture and a flavor that’s richer than most beans, which makes them a natural fit for Mediterranean-style dishes.

One practical note: a small percentage of people with a genetic condition called G6PD deficiency should avoid fava beans. For everyone else, they’re a legitimate high-protein option that doesn’t get nearly enough attention.

At a Glance: Roughly 13g protein per cooked cup. Rich, buttery flavor. Fresh versions require double-shelling; frozen or canned versions are much more practical.

7. Mung Beans

Mung beans show up in South Asian and Southeast Asian cooking constantly, and they deserve more attention in Western kitchens. A cooked cup provides around 14 grams of protein, and they cook faster than most legumes without soaking.

Sprouted mung beans are a different use case entirely. The sprouts deliver less protein per cup than cooked beans but add a crunchy texture to salads and stir-fries. The whole dried beans cook in about thirty minutes and absorb spices well in curries and soups.

At a Glance: Roughly 14g protein per cooked cup. No soaking required. One of the faster-cooking legumes available, making them practical for weeknight meals.

6. Black-Eyed Peas

Black-eyed peas carry a strong tradition in Southern cooking, where they’ve been a protein staple for generations. A cooked cup delivers around 13 grams of protein with an earthy, slightly smoky flavor that pairs naturally with greens, rice, and simple seasonings.

They cook faster than most dried beans and don’t require soaking if you’re short on time. They’re also one of the foods worth stocking up on before winter, as dried black-eyed peas store well for a year or more with no quality loss.

At a Glance: Roughly 13g protein per cooked cup. Long shelf life dried. Pairs naturally with leafy greens for a meal that covers protein and micronutrients in one pot.

5. Edamame

Edamame are young soybeans harvested before they harden, and they’re one of the few plant foods that deliver a complete protein. A cooked cup provides around 17 grams of protein with all the essential amino acids your body can’t produce on its own.

Frozen edamame in the shell or shelled takes about five minutes to prepare from frozen. Shelled edamame works in grain bowls, salads, stir-fries, or straight out of the bag as a snack. Few vegetables deliver this much usable protein this easily.

At a Glance: Roughly 17g protein per cooked cup. Complete protein. One of the fastest high-protein vegetables to prepare from frozen.

4. Winged Beans

Winged beans are not a common sight in most North American grocery stores, but they’re worth knowing about. Popular across Southeast Asia and parts of Africa, a cooked cup delivers around 18 grams of protein, putting them in the same category as lentils.

The entire plant is edible: leaves, pods, flowers, and tubers. The beans themselves have a nutty flavor and work well in stir-fries and curries. They’re also high in calcium, which is unusual for a legume. If you can find them at an Asian or international grocery store, they’re worth trying.

At a Glance: Roughly 18g protein per cooked cup. High in calcium. Not widely available in mainstream grocery stores but worth seeking at international markets.

3. Tempeh

Tempeh is fermented soybean cake, which puts it right at the intersection of vegetable-derived food and fermented superfood. A 3-ounce serving delivers around 16 to 17 grams of protein, and the fermentation process makes the protein more bioavailable than regular soybeans.

The texture is firm and slightly chewy, making it one of the better plant-based options for dishes that need something with substance. It takes marinades well, browns nicely in a hot pan, and holds up in sandwiches, bowls, and stir-fries. It’s also one of the fermented foods your grandmother was right about long before anyone used the word probiotic in casual conversation.

At a Glance: Roughly 16-17g protein per 3oz serving. Fermentation increases bioavailability. One of the best meat-texture alternatives for plant-based cooking.

2. Soybeans

Mature cooked soybeans are one of the most protein-dense foods in any category, plant or animal. A cooked cup delivers around 28 to 29 grams of protein, and like edamame, that protein is complete, meaning all essential amino acids are present.

They’re less common as a standalone dish in Western cooking compared to their processed forms like tofu, tempeh, and edamame. But whole cooked soybeans work in soups, stews, and grain bowls, and the nutrition they deliver is hard to match from a single plant food.

For anyone tracking protein on a plant-heavy diet, soybeans solve a lot of problems in a single ingredient. They’re also one of the better options for people who want high-protein meals without relying on meat at every sitting.

At a Glance: Roughly 28-29g protein per cooked cup. Complete protein. The most protein-dense legume widely available in North American grocery stores.

1. Green Peas (Fresh or Cooked, Full Breakdown)

Green peas take the top spot not just because of their protein content, which runs around 8 to 9 grams per cooked cup, but because of the full picture they represent. They’re affordable, available year-round fresh and frozen, require almost no preparation, and deliver a complete nutritional profile that makes them one of the most useful vegetables in any kitchen.

They’re also one of the few vegetables that provides a meaningful amount of protein in a form most people actually eat regularly. Edamame and soybeans are excellent but require a specific culinary context. Peas go into pasta, risotto, soups, fried rice, and side dishes without requiring anyone to think twice.

The protein in peas has also become the base of an entire category of protein powders and meat alternatives because of how well it works at the functional level. It’s a complete-ish protein, meaning it covers most essential amino acids in reasonable ratios.

Beyond protein, a cup of cooked peas delivers around 7 grams of fiber, meaningful amounts of vitamins A, C, and K, and more than 400mg of potassium. That’s a lot of nutritional work from something that costs a dollar a pound frozen. For anyone building meals around vegetables ranked by protein content, peas belong at the center of the conversation, not the side of it.

They’re also one of the gut-friendly foods with solid science behind them, given their prebiotic fiber content. The fact that they’re this useful and this inexpensive is the whole point of this list.

At a Glance: Roughly 8-9g protein per cooked cup. Year-round availability fresh and frozen. One of the most practical, affordable, and nutritionally complete vegetables available at any grocery store.

The Wrap-Up

If you’re building meals with more plant protein, start with what’s already easy: frozen peas, canned black beans, frozen edamame, and lentils. Those four alone cover most situations and cost very little per serving.

Pro Tip: Combining two incomplete plant proteins in the same meal, like rice and beans, or peas and whole grain pasta, covers the full range of essential amino acids without needing to think too hard about individual amino acid profiles. You don’t have to combine them at the same meal to benefit, but doing so makes the math easier.

For anyone looking at the bigger picture of what plant foods can do for both your health and your grocery bill, the low-calorie foods that barely register on a day’s count pair well with these high-protein vegetables to build meals that are filling without being heavy. And if you want to see how your current food spending stacks up, the budget calculator can show you exactly where the grocery money is going each month.

Vegetables can carry more of the protein load than most people give them credit for. The ones on this list prove it.
