Soybeans top the list for bean protein by weight; cooked mature soybeans deliver about 18–19 grams per 100 grams.
Scanning the pantry for a plant protein star? Beans make it easy. The question, which beans have the most protein? pops up for meal prep, weight goals, and budget cooking alike. Below you’ll see a quick ranking, then clear guidance on portions, cooking notes, and how to use each type so you get the most protein for the effort.
Which Beans Have The Most Protein — Per 100g Rankings
Numbers below reflect cooked beans, drained, plain. Protein per cup helpfully shows what lands in a typical bowl; the per-100g column lets you compare types fairly.
| Bean (Cooked) | Protein / 100g | Protein / 1 cup |
|---|---|---|
| Soybeans, mature | 18.2–18.6 g | ~31 g |
| Adzuki beans | ~7.5–8.1 g | ~17 g |
| Black beans | ~8.9 g | ~15.2 g |
| Kidney beans | ~8.7–9.0 g | ~15.3 g |
| Navy (haricot) beans | ~8.3–8.7 g | ~15.0–15.5 g |
| Pinto beans | ~9.1 g | ~15.4 g |
| Mung beans | ~7.0–7.5 g | ~14–15 g |
| Fava (broad) beans | ~7.6–7.7 g | ~13–14 g |
| Chickpeas | ~8.8–9.0 g | ~14–15 g |
| Edamame, shelled | ~11–12 g | ~18–19 g |
| Cannellini (large white) | ~9.9 g | ~17 g |
Takeaway: soybeans sit alone at the top on a per-weight basis. Next comes a tight pack of common pantry beans that land near 8–10 grams per 100 grams cooked. If you eat beans by the cup, the range clusters around 14–16 grams, with soy again pulling ahead.
Close Variant: Beans With The Most Protein, By Meal Use
Protein density matters, but so do texture and how you eat them. Here’s how the highest-protein beans fit common meals without fuss.
Soybeans And Edamame
Why they lead: Mature soybeans pack the most protein per bite and stand up in stews, curries, scrambles, and burger mixes. Edamame gives you a snack-ready option that still lands near 18–19 grams per cup.
Best uses: Toss cooked soybeans into grain bowls, blend into miso-like dips, or fold into chili for serious heft. Keep frozen edamame for quick bowls and stir-fries.
Black, Kidney, Pinto, And Navy
Why they’re easy wins: These pantry staples live near 8–9 grams per 100 grams. Flavor works across tacos, rice bowls, soups, and salads. Texture holds, so batch cooking pays off.
Best uses: Mash with spices for quick bean patties, stir through tomato-based sauces, or bake into casseroles. For salads, rinse canned beans and dress while still warm so they soak up seasoning.
Adzuki, Mung, And Fava
Why pick them: Adzuki brings a slightly sweet note and solid protein. Mung cooks fast and shines in dal, soups, and sprouts. Fava offers a meaty bite for stews and spreads.
Best uses: Try adzuki in grain bowls and veggie burgers. Use mung for quick pressure-cooker stews. Purée fava with lemon and garlic for a rustic spread or fold into shakshuka-style pans.
Method Matters: Dry Vs. Canned, Soaking, And Salt
Canned vs dry: Protein values shift a little with moisture and packing liquid. Rinsed canned beans land close to cooked-from-dry numbers. Sodium drops with a thorough rinse. Dry beans offer control over texture and seasoning but take planning.
Soaking: Overnight soaking cuts cook time and helps with digestion. A quick soak works too: boil five minutes, rest an hour, drain, then cook fresh.
Salt: Season the water once beans start to soften. Early salt gives better skins without turning them tough. Acid at the end brightens flavor.
Portions That Make Planning Simple
Here’s a plain guide to match servings with your protein target. The range reflects common products and water content.
| Serving | Protein | Notes |
|---|---|---|
| 1 cup cooked soybeans | ~31 g | Highest among beans; rich texture |
| 1 cup cooked edamame | ~18–19 g | Shelled, ready snack or bowl topper |
| 1 cup cooked black beans | ~15.2 g | Easy match for rice, tacos, salads |
| 1 cup cooked kidney beans | ~15.3 g | Great in chili and tomato sauces |
| 1 cup cooked pinto beans | ~15.4 g | Creamy; good for refried style |
| 1 cup cooked navy beans | ~15.0–15.5 g | Works in soups and baked dishes |
| 1 cup cooked chickpeas | ~14–15 g | Roast for crunchy snacks |
| 1 cup cooked fava beans | ~13–14 g | Thick bite; stews and spreads |
How To Choose Beans For Complete Meals
Amino acid angle: Most beans lack a little methionine. Pairing with grains, seeds, or eggs covers the gap. You don’t need to mix in the same bite; eating these foods across the day does the job.
- Beans + rice, quinoa, or corn tortillas
- Hummus + whole-grain pita
- Bean chili + cornbread
- Edamame + soba bowls
Cooking Tips That Protect Protein And Texture
Start With A Gentle Simmer
Keep the pot at a light simmer. A rolling boil can split skins and turn the pot chalky. Skim foam in the first few minutes; that keeps flavors clean.
Use Aroma, Not Just Salt
Bay leaves, garlic, onion, and whole spices build depth without extra steps. Tie herbs in a bundle for easy lifting after cooking.
Finish In The Liquid
Turn off the heat and let beans rest in the pot for ten to twenty minutes. Starch settles, skins relax, and seasoning evens out.
Where The Numbers Come From
Protein data in this guide reflect cooked, drained beans from reputable nutrient datasets. Soybeans, mature, cooked show protein near 18–19 grams per 100 grams and roughly 31 grams per cup, while black beans, cooked land near 8.9 grams per 100 grams and about 15.2 grams per cup. These numbers match everyday kitchen portions and help you compare types without guesswork.
What Changes The Protein Number
Water makes the spread: Protein values appear lower in soupier beans simply because water adds weight. When you compare protein per 100 grams, you standardize for that. When you compare per cup, packing and liquid level can nudge the figure a bit in either direction.
Bean age and variety: Older beans take longer and soak up water differently. Heirloom lines can show small swings in macronutrients. The practical point: use ranges, not single decimals, and plan meals by the cup or by the gram of cooked weight.
Seasoning choices: Oil, pork, or cheese change calories and macros. The protein in the bean stays steady; the plate total shifts with add-ins. If you want a leaner bowl, keep aromatics and herbs front and center and add richness with a spoon of yogurt or a splash of olive oil at the table.
Dry-To-Cooked Conversions That Help With Meal Prep
Most beans roughly triple in weight and volume when cooked. A cup of dry beans makes about three cups cooked. That means half a pound of dry beans sets you up for four to five generous side servings or two hearty mains.
For tight scheduling, cook once and portion into flat containers with some cooking liquid. The liquid keeps texture tender and seasons future dishes. Freeze in one-cup bags for easy protein math during busy weeks.
Protein Per Calorie
Soy leads for sheer grams. For a leaner ratio, black, kidney, navy, and pinto keep calories modest while protein stays steady.
Digestibility Tricks That Really Work
Rinse, Soak, And Cook Smart
Rinse well, soak, and start with fresh water. A pressure cooker saves time and keeps skins intact. Finish with lemon or vinegar for a bright bowl.
Simple Ways To Hit A Protein Target With Beans
Three easy patterns: a bean-and-grain bowl, a chickpea salad with lemon, and a navy bean soup with greens. Keep portions near one cup cooked for simple tracking.
Budget Notes And Pantry Strategy
Dry bags win on price per gram of protein; canned wins on speed. Choose low-sodium cans and rinse. Keep quick add-ins on hand to build a meal fast.
Safety And Quality Pointers
Red kidney beans must be boiled hard for at least ten minutes after soaking to neutralize natural lectins, then simmered until tender. Never slow-cook them from raw. Store cooked beans in the fridge up to four days. Reheat to a steamy simmer, especially if you stored them in the liquid.

Quick Picks By Goal
- Maximum grams: Choose soybeans or edamame, then build the plate with steamed greens and a grain.
- Lean ratio: Use black, kidney, navy, or pinto with a big salad and citrus.
- Fast weeknight: Open canned chickpeas or black beans, rinse, and toss with olive oil, lemon, and herbs.
- Meal prep: Cook a pound of dry beans, portion by the cup, and freeze flat for quick thawing.
Putting It Into Practice
Use soybeans when you need maximum plant protein in a tight calorie budget. Rotate black, kidney, pinto, and navy beans for steady 14–16 gram cups that carry soups, salads, and wraps. Reach for adzuki, mung, and fava when you want variety without losing much ground on protein.
Keep a simple weekly rhythm: batch-cook a pound of dry beans on the weekend, store in the cooking liquid, and scoop through the week. Or stock a few low-sodium canned options for fast meals. With that setup, answering “which beans have the most protein?” turns into picking the texture you want and the time you have. Keep a spoon, a lemon, and good salt within reach.
