Small, reddish-brown, and naturally mild with a slightly sweet, nutty flavor, adzuki beans are a versatile legume with a long history in East Asian cooking. They can be found in everything from savory soups and rice dishes to traditional sweet red bean pastes and desserts.
Also commonly spelled aduki beans, these small beans are easy to keep on hand and can be used in a surprising variety of recipes.
In this guide, you'll learn what adzuki beans are, how to cook them, their nutritional profile, how they're traditionally used, and how to store them for future meals.
What Are Adzuki Beans?
Adzuki beans are small legumes most commonly recognized by their deep reddish-brown color and distinctive white line along one side.
They have been cultivated in East Asia for centuries and are particularly common in Japanese, Chinese, and Korean cuisines.
Unlike larger beans with a strongly earthy flavor, adzuki beans have a relatively mild, subtly sweet and nutty taste. This makes them suitable for both savory meals and sweet recipes.

Organic Adzuki Bean Nutrition
Adzuki beans naturally provide a variety of nutrients commonly associated with legumes.
They naturally contain:
- Plant-based protein
- Dietary fiber
- Iron
- Potassium
- Magnesium
- Folate
- Phosphorus
Like many dried beans, adzuki beans can be an easy way to incorporate more legumes into soups, grain bowls, salads, and other everyday meals.
What Do Adzuki Beans Taste Like?
Cooked adzuki beans have a mild, nutty and subtly sweet flavor.
Their natural sweetness is one of the characteristics that distinguishes them from many other beans and helps explain their traditional use in desserts.
When cooked until tender, adzuki beans develop a soft, creamy interior while still working well in dishes where you want the beans to retain some of their shape.
Their flavor pairs well with both savory seasonings and sweeter ingredients.
How to Cook Organic Adzuki Beans
Cooking dried adzuki beans is straightforward.
Step 1: Sort and Rinse
Sort through the dried beans and remove any debris or damaged beans.
Rinse thoroughly under cool running water.
Step 2: Soak
Adzuki beans can be soaked before cooking to help shorten the cooking time and encourage more even cooking.
Cover the beans with plenty of water and soak for several hours or overnight.
Step 3: Drain
Drain the soaking water and rinse the beans again.
Step 4: Cook
Transfer the beans to a pot and cover them generously with fresh water.
Bring the water to a boil, then reduce the heat and simmer gently until the beans are tender.
Cooking time can vary depending on the age of the beans, whether they were soaked, and your preferred texture, so check them periodically as they cook.
Â
Do Adzuki Beans Need to Be Soaked?
Not necessarily.
Because adzuki beans are relatively small, they can be cooked without soaking. However, soaking them beforehand can reduce cooking time and may help the beans cook more evenly.
If you don't have time to soak them overnight, simply rinse the beans thoroughly and allow additional time for cooking.

What Can You Make With Adzuki Beans?
One of the most interesting things about adzuki beans is their ability to work in both savory and sweet recipes.
Popular uses include:
- Soups
- Stews
- Curries
- Rice dishes
- Grain bowls
- Bean salads
- Vegetable dishes
- Bean patties
- Sweet red bean paste
- Traditional Asian desserts
Their mild flavor also makes them easy to experiment with in recipes that would normally call for other small beans.
Adzuki Beans in Sweet Recipes
Adzuki beans have an especially interesting role in East Asian desserts.
In Japan, cooked adzuki beans are commonly sweetened with sugar to make anko, or sweet red bean paste. The paste can have a smooth or more textured consistency depending on how it is prepared.
Sweetened adzuki beans and red bean paste are traditionally used in foods such as:
- Mochi
- Dorayaki
- Buns and pastries
- Rice cakes
- Traditional desserts
For someone accustomed to using beans only in savory recipes, adzuki beans are a great example of just how versatile legumes can be.
Adzuki Beans in Savory Recipes
You don't have to make dessert to enjoy adzuki beans.
Cooked adzuki beans can be added to soups, stews, curries, salads, and grain bowls much like other dried beans.
Try pairing them with:
- Brown rice
- Quinoa
- Leafy greens
- Sweet potatoes
- Carrots
- Mushrooms
- Ginger
- Garlic
- Sesame
Their relatively mild flavor allows herbs, spices, sauces, and other ingredients to take center stage.
Adzuki Beans vs. Kidney Beans
Adzuki beans and kidney beans may both have reddish coloring, but they're distinctly different beans.
| Adzuki Beans | Kidney Beans |
| Small and oval | Larger and kidney-shaped |
| Mild and subtly sweet | Earthier, more robust flavor |
| Common in East Asian cooking | Common in chili and many Western dishes |
| Used in savory and sweet recipes | Primarily used in savory recipes |
While they can sometimes serve similar purposes in savory meals, their different sizes, textures, and flavors mean they aren't always direct substitutes for one another.
