Cooked soybeans top the list at about 31 g protein per cup; black, kidney, pinto, navy, and adzuki follow with roughly 14–17 g per cup.
Looking for the beans with the most protein? You’re in the right place. This guide ranks popular cooked beans by protein per cup, explains what “high-protein” means in real meals, and shows how to build balanced plates that hit your daily targets without fuss.
Beans With The Highest Protein Content — Ranked By Cup
Here’s a practical ranking of cooked beans by protein per 1 cup serving you’re likely to scoop from a pot or drain from a can. Values below reflect plain, cooked beans (no oil or sauce).
| Bean (Cooked) | Protein Per Cup (g) | What This Means In Meals |
|---|---|---|
| Soybeans (edamame/soy) | ~31.3 | One cup can cover about half a typical day’s protein target for many adults. |
| Adzuki | ~17.3 | Solid base for grain bowls where you still want room for veggies and sauces. |
| Kidney (red) | ~15.3 | Chili staple; two cups land near ~30 g without adding meat. |
| Pinto | ~15.4 | Great in refrieds or stews; pairs well with rice or corn tortillas. |
| Black | ~15.2 | Taco night hero; combine with corn salsa for a quick lift. |
| Navy (haricot) | ~15.0 | Perfect for soups; thickens broth while adding steady protein. |
| Chickpeas | ~14.5 | Roast for crunch or blitz into hummus; easy snack protein. |
| Great Northern | ~14.7 | Mild flavor fits creamy blends and white chili. |
| Lima (butter beans) | ~14.7 | Velvety texture; lovely in stews with greens and lemon. |
| Fava (broad beans) | ~12.9 | Earthy bite; mash with olive oil and herbs for a spread. |
How Much Protein Do You Actually Need?
Most adults do well starting around 0.8 g protein per kg body weight per day. That’s about 54–70 g for many people, adjusted to your size and activity. If you lift or train hard, you may aim higher within evidence-based ranges from sports nutrition groups. The goal: hit your daily total across meals you enjoy.
Quick math: if lunch brings 1 cup of black beans (~15 g) and dinner adds 1 cup of chickpeas (~14–15 g), you’ve banked ~30 g from beans alone, before counting grains, veggies, dairy, eggs, fish, or meat you might also eat.
Protein Density By Weight (Cooked, 100 g Portions)
Cup sizes vary by bean and brand. When you want a strict weight-based view, use protein per 100 g. It helps for meal prep and macros.
| Bean (Cooked) | Protein Per 100 g (g) | Handy Serving Tip |
|---|---|---|
| Soybeans | ~18.6 | Warm with ginger and scallions; sprinkle sesame seeds. |
| Pinto | ~9.1 | Mash with a splash of broth and lime for quick “refrieds.” |
| Black | ~9.0 | Rinse canned beans, toss with corn, onions, and cilantro. |
| Navy | ~8.3 | Simmer with garlic, carrots, and bay leaf for a cozy soup. |
| Adzuki | ~7.6 | Great in rice bowls with pickled veg and a soy-lime drizzle. |
| Lima | ~7.8 | Blend with olive oil and lemon into a silky bean purée. |
| Fava | ~7.6–7.8 | Sauté with garlic and mint; finish with a squeeze of lemon. |
Why Soybeans Often Sit At The Top
Soybeans pack standout protein per cup and per 100 g. They’re also easy to slot into day-to-day meals: steamed edamame with sea salt, miso-ginger soups, tempeh stir-fries, or tofu scrambles. If you’re dialing protein up while watching calories, soy helps you climb fast without leaning on meat every time.
Bean Protein Quality In Plain Terms
Most beans are rich in lysine but lighter on methionine. No stress: you don’t need to pair foods in the same bite. Eat a varied menu across the day and your amino acid puzzle comes together. Grains, seeds, dairy, eggs, fish, or meat you already eat round things out.
Serving Sizes That Hit Real Targets
Quick Wins At 15–30 Grams
- 15 g: 1 cup black beans tucked into tacos with salsa and onions.
- ~30 g: 1 cup adzuki in a grain bowl or 2 cups of kidney bean chili.
- ~31 g: 1 cup soybeans as a warm side, plus a citrusy salad.
Mix And Match For Balance
Beans bring protein, fiber, iron, potassium, and folate in one scoop. Add grains for energy, vegetables for volume and vitamin C (helps non-heme iron), and a tasty fat like olive oil or tahini for mouthfeel. That’s a satisfying plate that works on busy nights.
How Canned Vs. Dried Beans Compare
Both are nutritious. Canned beans win on speed; drain and rinse to cut sodium. Dried beans let you fine-tune texture and salt from the start. Pressure cookers turn long soaks into weeknight-friendly timing.
Cooking Tweaks That Protect Protein
- No need to baby protein: Standard simmering doesn’t “destroy” it. Protein is sturdy in normal home cooking.
- Season smart: Salt the cooking water late to keep skins tender if you prefer a softer bite; the protein stays put.
- Cool and store well: Refrigerate within two hours; cooked beans keep 3–4 days or freeze for a month.
Beans With The Highest Protein Content In Everyday Dishes
Build meals around your top picks without making the plate feel heavy. A few ideas:
