Differences Between Red Beans and Kidney Beans

While most people confuse red beans and kidney beans, there are various factors that you can use to distinguish the two groups.

The beans’ color, texture, and shape are the basic distinguishing features between the two groups.

Size

Kidney beans are larger than red beans. The small size of red beans is one of their key distinguishing features.

Shape

Kidney beans are shaped like a kidney, hence the name. Red beans are oval-shaped and small, commonly referred to as small red beans.

For most people, it is easier to identify and differentiate the two varieties based on shape.

Color

Red beans are pink-red and look bright. On the other hand, kidney beans are crimson red. It is important to note that some kidney beans come in different colors depending on the variety.

Most people confuse red beans with dark red kidney beans. When unsure, check the size and shape of the beans.

Flavor

Red beans have a beany flavor; depending on the variety, some have nutty undertones. Kidney beans have a meaty taste, and they are slightly sweet.

When cooking with other ingredients, red beans maintain their beany flavor. On the contrary, kidney beans easily absorb the flavor of spices and other ingredients while you cook.

Texture

Kidney beans have thick and firm skin, which appears as a rough texture. Even if you cook kidney beans fully, they will be dense and harder on the inside. On the other hand, red beans are smooth and creamier.

Despite these differences, red beans and kidneys are easily interchangeable in most recipes without a significant change in flavor.

Varieties

Many varieties of beans are red; hence, the name can be confusing. For instance, some kidney beans come in red but are not classified under red beans.

Differences in Preparation

The preparation of red beans and kidney beans depends on the condition of the beans.

Second, you can use the quick soak method [4] when in a hurry. After soaking the beans, you should rinse them and boil them for a few minutes. Leave them for about an hour soaking in hot water.

Thirdly, you can consume canned red beans directly from their containers. However, canned red beans have more sodium than dried beans.

Both red beans and kidney beans work well with onions and garlic.
