The kidney bean, scientifically known as Phaseolus vulgaris, is a staple in many cuisines around the world, and the United States is no exception. However, navigating the American grocery store aisle can lead to confusion, as this common legume goes by a variety of names depending on the culinary context, regional dialect, and even slight differences in the bean itself. While the primary and most descriptive name is indeed 'kidney bean,' Americans frequently use other terms like 'red beans' or 'chili beans.' Unpacking these different labels helps to understand the subtle distinctions in American cooking and food culture.
The Primary Name: The Common Kidney Bean
For most of the country, the large, kidney-shaped, and distinctly red bean is simply known as the kidney bean. This moniker is used consistently on canned goods, in national cookbooks, and in general conversation. It is the default term for the large, plump, red bean prized for its firm texture and ability to absorb flavors, making it ideal for robust, slow-cooked dishes. The scientific classification of the kidney bean places it within the species Phaseolus vulgaris, which also includes pinto, black, and cannellini beans. While the term is unambiguous for the large red bean, its simple use doesn't account for the regional variations that add complexity to the American culinary lexicon.
Red Beans vs. Kidney Beans: A Regional Difference
Perhaps the most significant source of confusion is the distinction between kidney beans and 'red beans.' In the United States, especially in New Orleans and southern Louisiana, the term "red beans" refers to a smaller, rounder, and lighter red bean variety. This specific bean is the essential ingredient for the iconic Creole Monday dish of red beans and rice. The smaller red bean is softer and creamier when cooked, making it perfect for the long, slow simmer required for this comfort food. The larger, firmer kidney bean can be substituted in a pinch, but it will not achieve the same creamy texture. This regional specificity is a key detail that Americans in other parts of the country might not know, leading to ingredient mix-ups. To locals, the difference is not just semantic; it's a culinary necessity rooted in tradition.
The "Chili Bean" Moniker
Another common term used by Americans is "chili bean," which can be less of a descriptor for a specific bean type and more for a culinary application. A can labeled "chili beans" often contains kidney beans or pinto beans already soaked in a spicy sauce, ready to be added directly to chili con carne. However, the term can also colloquially refer to the kidney bean itself, as it is a widely used and classic ingredient in chili recipes. The flexibility of the kidney bean—its robust shape that holds up well in a long-simmering chili—makes it a top choice, thus earning it the alternate name. While this usage is common, it's important to remember that 'chili bean' isn't a botanical classification but a functional one, distinguishing it from other beans used for different purposes.
Other American Names and Varieties
Beyond the red varieties, some white beans also fall under the "kidney bean" umbrella in America. Cannellini beans, a large, creamy white bean popular in Italian cooking, are frequently called "white kidney beans". This name highlights their shared shape and botanical heritage with their red counterparts. The larger family of beans known as Phaseolus vulgaris also includes other varieties commonly found in American markets, such as pinto and navy beans, though they are not typically called kidney beans. These distinctions underscore how specific shape, color, and culinary tradition guide naming conventions in American food culture.
Popular American Dishes with Kidney Beans
- Chili con carne: The quintessential American dish where kidney beans are a key, and often mandatory, ingredient, providing hearty substance and texture.
- Classic Bean Salads: Kidney beans are a staple in cold three-bean or four-bean salads, where their firm texture holds up well with corn, green beans, and other vegetables.
- Hearty Soups and Stews: Kidney beans add protein and fiber to a variety of slow-cooked soups, absorbing the rich flavors of the broth.
- Tex-Mex Cuisine: While pinto beans are more traditional for refried beans, kidney beans are sometimes used in other Tex-Mex style dishes.
- Red Beans and Rice: In New Orleans, this is specifically made with smaller red beans, though kidney beans are a common and widely accepted substitute elsewhere.

Conclusion
Ultimately, the answer to what Americans call kidney beans is more complex than a single name. While "kidney bean" is the standard term for the large, red variety, the context of American cooking reveals a more diverse lexicon. Regional traditions, like those in Louisiana where a smaller "red bean" is preferred, and descriptive colloquialisms, such as "chili bean," all play a part in shaping the language around this versatile legume. For the average American consumer, the label on the can is often the final word, but understanding the nuance behind these different names enriches one's appreciation for the country's diverse culinary landscape.
