Vegetables that are high in protein: a complete guide with numbers

Vegetables that are high in protein include green peas, spinach, broccoli, sweet corn, Brussels sprouts, and mushrooms. While no single vegetable replaces dal or paneer, adding protein-rich vegetables to every meal can boost daily intake by 10–15 g without extra calories. This matters especially for vegetarians trying to increase protein without supplements.

Why vegetables matter for protein and muscle building

Most people think of eggs, chicken, or whey when they hear protein. Vegetables rarely come to mind. Yet several common vegetables deliver 2–5 g of protein per 100 g cooked serving. That may sound modest, but it adds up fast across three or four meals a day.

According to the FAO nutrient requirements database, the average sedentary adult needs about 0.8 g of protein per kg of body weight daily. For a 65 kg person, that is roughly 52 g. When vegetables contribute even 10–12 g of that total, the remaining gap becomes much easier to fill with dal, grains, and dairy.

Protein from vegetables also comes packaged with fibre, vitamins, and minerals. This makes it especially useful for people managing weight or blood sugar. India faces a widespread protein deficiency crisis, and vegetables can be part of the solution.

Top vegetables that are high in protein (per 100 g cooked)

Below is a ranked list based on protein content per 100 g of cooked vegetable. Values are sourced from the Indian Food Composition Tables (IFCT 2017) and USDA FoodData Central.

• Green peas: 5.4 g protein per 100 g cooked. Also rich in fibre and vitamin C.
• Edamame (young soybeans): 11.9 g per 100 g cooked. One of the highest-protein vegetables available.
• Sweet corn: 3.4 g per 100 g cooked. Provides slow-release carbohydrates alongside protein.
• Spinach: 2.9 g per 100 g cooked. A concentrated source because it shrinks significantly on cooking.
• Broccoli: 2.8 g per 100 g cooked. Supplies sulforaphane, an antioxidant linked to reduced inflammation.
• Brussels sprouts: 3.4 g per 100 g cooked. Also high in vitamin K and folate.
• Asparagus: 2.2 g per 100 g cooked. Low in calories and a natural source of iron.
• Mushrooms (white button): 3.1 g per 100 g cooked. Provide vitamin D when exposed to sunlight.
• Kale: 2.9 g per 100 g cooked. Dense in calcium and antioxidants.
• Potatoes: 2.0 g per 100 g cooked. Often overlooked, but the volume consumed makes its contribution meaningful.

Edamame stands out because it contains all nine essential amino acids. Most other vegetables are low in one or more essential amino acids. This is why pairing matters, which the next section covers. For a broader list that includes legumes and grains, see this guide on plant protein sources in India ranked by protein per 100 g.

How to pair vegetables for complete protein

A complete protein contains all nine essential amino acids in adequate amounts. Most vegetables are limited in methionine or lysine. The fix is simple: combine them with complementary foods.

• Vegetables + grains: Broccoli stir-fry with brown rice. Peas pulao with multigrain roti.
• Vegetables + legumes: Spinach with chana dal. Mushroom and rajma curry.
• Vegetables + seeds or nuts: Kale salad with pumpkin seeds. Asparagus topped with sesame.

These pairings do not need to happen in the same meal. Eating complementary amino acids within the same day is sufficient, according to research published in the Journal of the International Society of Sports Nutrition. The outdated idea of combining proteins at every single meal has been revised. For those building muscle on a plant-based diet, the article on strength training without whey for Indian vegetarians covers this in more detail.

How much protein can vegetables realistically add to a daily diet?

Consider a typical Indian vegetarian plate. Two rotis, a sabzi, dal, rice, and salad. If the sabzi uses 150 g of cooked green peas and 100 g of spinach, that single dish provides roughly 11 g of protein. Add a mushroom side dish at dinner with 100 g cooked mushrooms, and that is another 3 g.

In total, vegetables alone contribute about 14 g across the day. Combined with dal, roti, curd, and snacks, reaching 50–60 g becomes realistic without any supplements. Those aiming higher can refer to the guide on how to eat 100 g of protein daily on a vegetarian diet.

A sample day with high-protein vegetables

• Breakfast: Multigrain cheela stuffed with 100 g spinach and paneer. Protein from vegetables: ~3 g.
• Lunch: Peas pulao (150 g peas) with raita. Protein from vegetables: ~8 g.
• Snack: Steamed edamame (50 g). Protein from vegetables: ~6 g.
• Dinner: Broccoli and mushroom stir-fry (100 g each) with roti. Protein from vegetables: ~6 g.

Total vegetable protein contribution: approximately 23 g. That is close to half the daily requirement for many adults.

Common mistakes when counting protein from vegetables

Confusing raw and cooked weights

Spinach loses up to 90% of its volume when cooked. So 100 g of raw spinach becomes roughly 10 g cooked. Always check whether the protein value refers to raw or cooked weight. USDA and IFCT databases specify this clearly.

Assuming vegetables alone are enough

Even with the best vegetable choices, protein from vegetables alone cannot meet the full daily requirement. They are a supplementary source. The foundation should still be dal, paneer, curd, eggs, or other concentrated protein foods. The question of whether dal alone is enough protein is worth reading for added context.

Ignoring cooking methods

Deep-frying vegetables in batter adds calories without meaningful extra protein. Steaming, sautéing, or light stir-frying preserves nutrients better. Overcooking in excess water can also leach water-soluble vitamins like vitamin C and B-complex.

Overlooking frozen vegetables

Frozen peas, broccoli, and corn retain nearly the same protein content as fresh. According to a study published in the Journal of Food Composition and Analysis, flash-frozen vegetables can be nutritionally comparable to fresh produce stored for several days. They are convenient, affordable, and reduce food waste.

Vegetables and muscle building: what the research says

Muscle protein synthesis (MPS) requires an adequate dose of leucine, an essential amino acid. Most vegetables are low in leucine compared to dairy or meat. However, combining high-protein vegetables with grains and legumes can bring leucine levels closer to the threshold needed for MPS.

A 2021 meta-analysis in Sports Medicine found that plant-based diets can support muscle gains comparable to omnivorous diets, provided total protein intake is sufficient and sources are varied. Vegetables contribute to this variety.

For those working out regularly, pairing protein-rich vegetables with a post-workout real food meal can effectively support recovery and growth.

Special considerations for different life stages

Children and picky eaters

Peas and sweet corn are usually accepted by children more readily than spinach or broccoli. Blending spinach into cheelas or parathas is a practical trick. Even a 50 g addition of peas to a child's meal adds about 2.7 g of protein.

Adults over 40

After age 40, muscle loss accelerates. The protein requirement goes up to 1.0–1.2 g per kg of body weight. Every additional gram of protein matters. Vegetables become a useful tool when combined with concentrated sources. The guide on protein and muscle loss after 40 explains this in detail.

Pregnancy and breastfeeding

Protein needs increase by 15–25 g per day during pregnancy and lactation. Iron-rich vegetables like spinach and broccoli pull double duty by contributing both protein and iron.

Quick reference table: protein in popular Indian vegetables

This table shows protein values per 100 g of cooked vegetable for items commonly found in Indian kitchens.

• Green peas (matar): 5.4 g
• Cluster beans (guar): 3.2 g
• Drumstick leaves (moringa): 5.3 g
• Spinach (palak): 2.9 g
• Fenugreek leaves (methi): 2.6 g
• Broccoli: 2.8 g
• Mushrooms (button): 3.1 g
• Sweet corn (makka): 3.4 g
• Cauliflower (gobi): 1.9 g
• French beans: 1.8 g

Moringa leaves deserve a special mention. They are exceptionally nutrient-dense and available across most of India. Just 100 g of cooked moringa leaves provides over 5 g of protein along with significant iron and calcium.

Frequently asked questions

Which vegetable has the most protein?

Edamame (young soybeans) tops the list at 11.9 g per 100 g cooked. Among commonly used Indian vegetables, green peas lead at 5.4 g per 100 g cooked.

Can vegetables replace dal or paneer for protein?

No. Vegetables are a supplementary protein source. Dal provides 7–9 g per cooked cup, and paneer provides about 18 g per 100 g. Vegetables work best alongside these staples.

Do vegetables provide complete protein?

Most vegetables do not. Edamame is an exception. Other vegetables should be combined with grains, legumes, or dairy to cover all essential amino acids.

Is raw or cooked vegetable protein content different?

The protein per gram of dry matter stays the same. However, cooking reduces water content in some vegetables and increases it in others. Always compare values for the same preparation method (raw vs cooked).

Are protein-rich vegetables good for weight loss?

Yes. High-protein vegetables tend to be low in calories and high in fibre. Green peas, broccoli, and spinach are all excellent choices for anyone on a calorie deficit who still needs adequate protein.
