Per 100 g cooked black beans provide about 132 calories and 8.9 g protein, or roughly 114 calories and 7.6 g protein per half-cup serving.
Black beans sit in a sweet spot: plenty of plant protein, lots of fiber, and a calorie load that still leaves room on your plate for other foods. If you eat them often, it helps to know exactly what those spoonfuls bring in terms of energy and protein so you can plan bowls, burritos, and soups with real numbers, not guesses.
This guide breaks down black beans calories and protein by weight, by common serving sizes, and in comparison with other beans. You’ll see where they fit in your daily protein target and how to use them in meals without blowing past your calorie budget.
Black Beans Calories And Protein Basics
Most nutrition databases use cooked, boiled, unsalted beans as the reference. Per 100 grams cooked, black beans provide about 132 kilocalories and 8.9 grams of protein, along with around 23–24 grams of carbohydrate and less than 1 gram of fat, based on data derived from the USDA’s legume tables. One full cup of cooked black beans, about 172 grams, gives roughly 227 kilocalories and 15 grams of protein, which lines up with figures reported by Healthline and similar nutrition resources.
Because nobody cooks or eats beans in perfect 100-gram blocks, it helps to translate those numbers into real-life portions such as tablespoons and cups. The table below uses cooked, plain beans as a baseline and rounds to one decimal place where needed so the numbers stay practical for everyday meal planning.
| Serving | Calories (kcal) | Protein (g) |
|---|---|---|
| 100 g cooked black beans | 132 | 8.9 |
| 1/2 cup cooked (about 86 g) | 114 | 7.6 |
| 1 cup cooked (about 172 g) | 227 | 15.2 |
| 2 tbsp cooked (about 30 g) | 40 | 2.6 |
| 1/4 cup canned, drained, low-sodium | 55 | 3.5 |
| 1/2 cup canned, drained, low-sodium | 109 | 7.0 |
| 1 oz dry black beans (about 28 g, uncooked) | 95 | 6.0 |
Per 100 Grams Versus Per Cup
Per 100 grams, black beans look like a solid protein source, but one cup gives a clearer picture of what lands in a hearty serving. At about 227 kilocalories and 15 grams of protein per cup, cooked black beans can match a small piece of meat on protein while bringing along roughly 15 grams of fiber and a broad mix of minerals, including magnesium, iron, and potassium. That one-cup figure comes directly from nutrient tables used by sources such as USDA FoodData Central and summarized by platforms that draw on the same dataset.
A half cup, which many labels treat as one serving, works well when beans are just one part of a meal. You still get around 7–8 grams of protein and more than 7 grams of fiber, but with roughly half the calories of a full cup. That range helps you plug black beans into anything from a light salad to a dense burrito without guessing.
Cooked Versus Canned Black Beans
Canned black beans are convenient and usually very close in calories and protein to home-cooked beans. A half cup of canned beans, drained and rinsed, lands near 100–110 kilocalories with roughly 6–7 grams of protein. The main difference often comes from added salt. That’s why many dietitians suggest choosing no-salt-added cans when possible and rinsing them under running water before cooking.
If you cook from dry, the numbers still trace back to the same beans. Dry beans are more energy dense by weight before cooking because they contain less water, which is why one ounce of dry beans already carries close to 95 kilocalories and around 6 grams of protein. After soaking and boiling, that same ounce swells and spreads those calories and protein across a larger cooked portion.
Black Bean Calories And Protein By Portion Size
Portion size makes a big difference when you use black beans as a main protein source. A taco night where each tortilla holds only two tablespoons of beans will not deliver the same protein as a grain bowl piled with a full cup. Because of that, it helps to think in building blocks: two tablespoons, a quarter cup, a half cup, and a full cup.
Two tablespoons of cooked black beans bring only about 40 kilocalories and a little under 3 grams of protein. That amount adds flavor and texture but does very little for daily protein goals. A quarter cup doubles that protein, while a half cup starts to feel meaningful: around 7–8 grams. Once you reach a full cup in a bowl or burrito filling, black beans take on the role of a true protein anchor alongside their fiber.
Mixing Beans With Grains And Vegetables
On their own, black beans have an amino acid profile that pairs well with grains. A cup of cooked rice adds about 4–5 grams of protein and roughly 200 kilocalories. Put one cup of cooked black beans together with one cup of cooked brown rice and you arrive near 430 kilocalories and about 20 grams of protein, plus plenty of fiber from both ingredients.
Add chopped vegetables and a small sprinkle of cheese and you can build a bowl that lands near 500–550 kilocalories with 22–25 grams of protein. That kind of meal works well when you want to center plants without giving up a satisfying protein hit. It also shows how small tweaks in portion size, such as using half a cup of rice instead of a full cup, can shave off calories while leaving black beans as the main protein contributor.
Examples From Everyday Meals
In a simple black bean soup, a serving might include three quarters of a cup of beans along with broth and vegetables. That gives about 170–180 kilocalories from beans alone and roughly 11–12 grams of protein before you count anything else in the bowl. A burrito stuffed with one cup of black beans, rice, and toppings can push past 600 kilocalories, but the beans still account for around 227 kilocalories and 15 grams of protein.
Salads often use half a cup of beans. That one scoop adds around 114 kilocalories and 7–8 grams of protein, turning a bowl of greens from a side dish into something that holds you between meals. These examples show how black beans calories and protein slide up and down as you adjust volume, while the basic ratio stays consistent.
How Black Beans Fit Into Daily Protein Targets
Many national guidelines suggest that healthy adults start around 0.8 grams of protein per kilogram of body weight per day, then adjust based on age, activity level, and specific health needs. For a 70-kilogram person, that baseline sits near 56 grams of protein a day. With roughly 15 grams of protein in a cup, cooked black beans can cover around a quarter of that target on their own.
Someone eating three meals a day might aim for 15–25 grams of protein at each meal. One cup of beans brings you into that range even before adding grains, dairy, eggs, or other plant proteins. Half a cup works well as a side that nudges a meal toward a stronger protein spread. That’s why dietitians quoted by outlets such as Harvard’s Nutrition Source and the American Heart Association keep pointing to beans, including black beans, as an easy plant protein to slot into regular meals.
Balancing Calories With Protein
Protein never arrives alone. With black beans, most calories come from complex carbohydrates and fiber, not from fat. Per 100 grams, you get around 24 grams of carbohydrate, roughly 9 grams of protein, and less than a gram of fat. That mix keeps the calorie density moderate while still bringing a noticeable protein dose.
If you are trying to keep calories steady while raising protein, black beans help by letting you swap part of a refined grain or fatty meat portion with a bean portion. Replace half a cup of white rice with half a cup of black beans and you trade a similar calorie load for much more protein and fiber. Over the course of a week, those swaps can shift your overall pattern toward more plant protein without a complicated plan.
How Black Beans Compare To Other Beans For Calories And Protein
Black beans sit in the same ballpark as other cooked beans when you compare calories and protein per 100 grams. Chickpeas, lentils, and pinto beans all fall within a similar energy range, with small shifts in protein content. Data drawn from USDA-linked tables shows that cooked chickpeas carry about 164 kilocalories and 8.9 grams of protein per 100 grams, while boiled lentils sit near 116 kilocalories and 9 grams of protein over the same weight.
The table below sets black beans side by side with a few common options. All values refer to cooked, boiled, unsalted beans where possible and use rounded numbers for clarity.
| Bean (Cooked, 100 g) | Calories (kcal) | Protein (g) |
|---|---|---|
| Black beans | 132 | 8.9 |
| Pinto beans | 143 | 9.0 |
| Kidney beans | 127 | 8.7 |
| Chickpeas (garbanzo) | 164 | 8.9 |
| Lentils | 116 | 9.0 |
What This Comparison Means In Practice
From a calorie and protein standpoint, black beans hold their own. They are not the highest protein pick in the legume shelf, but they match lentils and chickpeas closely and land near the middle of the calorie range. That means you can swap black beans for other beans in many recipes without huge changes in energy intake or protein totals.
The choice then comes down to flavor, texture, and what else you are eating. Black beans bring a soft, creamy bite and a deep color that works well in Latin American and Caribbean dishes, rice bowls, and burgers. If you already like the taste, the numbers show that you are getting a solid return on both calories and protein in each serving.
Practical Ways To Use Black Beans For Protein
Knowing that black beans calories and protein stay consistent across servings makes it easier to treat them like any other staple. A few habits go a long way. Keep cooked beans in the fridge so you can spoon half a cup onto salads, grain bowls, and eggs. Use a full cup when you want a plant-based main in a burrito or stew, then build vegetables and toppings around that anchor.
If you cook from dry, make a large batch once or twice a week. Soak the beans, boil them until tender, and portion them into containers. Each container can hold one or two cups, so you always know how many kilocalories and grams of protein you are adding to a dish. That simple batch-cooking rhythm turns black beans into an easy plug-and-play protein source for lunch boxes and quick dinners.
Pairing Black Beans With Other Protein Sources
Black beans work well with eggs, tofu, grilled chicken, or fish when you want a mixed plate. Even a quarter cup of beans next to another protein gives a bump in fiber and brings a different texture. Because the calorie load stays modest, you can add beans to soups, chilis, and casseroles without pushing the meal into a very high energy range.
Over time, those small additions add up. A half cup of black beans a day brings around 800 extra kilocalories and roughly 50 grams of extra protein over a full week. For many people, that kind of shift can move the daily average closer to recommended protein intakes while keeping meals affordable and easy to prepare.
Key Takeaways On Black Beans Calories And Protein
Per 100 grams cooked, black beans give about 132 kilocalories and close to 9 grams of protein. A full cup doubles those numbers, reaching about 227 kilocalories and 15 grams of protein, which puts black beans on the map as a steady plant-based protein source rather than a simple side dish.
When you line up black beans calories and protein against other beans, they look right in line with chickpeas, lentils, pinto beans, and kidney beans. That means you can choose them for taste and texture without worrying that you are giving up protein or packing in extra calories. With a basic sense of portion sizes and the numbers behind them, it becomes easy to use black beans as a regular feature in meals that feel satisfying, balanced, and grounded in real nutrition data.
