What is Red Bean Paste?
Red bean paste is a sweet paste made from adzuki beans (also called azuki or red mung beans) that is widely used in East Asian cuisine. The beans are boiled until soft, mashed, and then sweetened with sugar. The resulting paste can be smooth (koshian) or chunky (tsubuan), depending on the preparation method and desired use. It serves as a sweet, earthy filling for a huge variety of desserts and snacks.

Ingredients You’ll Need
Making this recipe requires just a few simple ingredients. The quality of your adzuki beans is key, so try to find a good brand at your local Asian market or online.
- Dried Adzuki Beans: The star of the show! These small, reddish-brown beans have a sweet, nutty flavor perfect for desserts.
- Granulated Sugar: This provides the sweetness. You can adjust the amount up or down based on your personal taste.
- Water: For soaking and cooking the beans until they are perfectly tender.
- A Pinch of Salt: Just a small amount enhances the sweetness and adds a layer of complexity to the flavor profile.

How to Make Homemade Red Bean Paste
Follow these simple steps to create a rich and delicious paste. The process is mostly hands-off, with the stove doing most of the work. Patience is the key to perfectly soft beans.
Step 1: Wash and Soak the Adzuki Beans
First, rinse the dried adzuki beans under cold running water to remove any dust or debris. Place the rinsed beans in a large bowl and cover them with at least three times their volume of cold water. Let the beans soak for at least 8 hours, or overnight. They will absorb a significant amount of water and double in size.
Step 2: Cook the Beans
Drain the soaked beans and transfer them to a large pot or Dutch oven. Cover the beans with fresh water, ensuring there is about 2 inches of water above the beans. Bring the pot to a boil, then reduce the heat to a gentle simmer. Cook for 60 to 90 minutes, or until the beans are very tender and can be easily mashed with a fork. Skim off any foam that rises to the surface during cooking.
Step 3: Sweeten and Thicken the Paste
Once the beans are tender, drain any excess water. You can do this by pouring the contents through a fine-mesh sieve, but be careful not to lose any of the softened beans. Return the beans to the pot. Add the granulated sugar and the pinch of salt. Over medium-low heat, use a potato masher or the back of a wooden spoon to mash the beans into a paste. Continue to stir the paste constantly to prevent it from burning. The mixture will thicken as the sugar dissolves and the moisture evaporates. Cook for about 10-15 minutes, until it reaches your desired consistency.
Step 4: Cool and Store
Remove the pot from the heat and let the red bean paste cool completely. It will thicken further as it cools. Once cooled, your homemade anko is ready to be used in your favorite recipes. It reminds me of the rich, sweet fillings found in some of my favorite treats, almost like a homemade chocolate sauce but with a unique, earthy flavor.
Tips for the Perfect Texture
One of the best parts of making your own red bean paste is customizing the texture. Here’s how to get it just right:
- For a Chunky Paste (Tsubuan): Follow the recipe as written. Mashing the beans in the pot will naturally leave some texture from the skins and bean pieces.
- For a Smooth Paste (Koshian): For a silky-smooth texture, you’ll need an extra step. After boiling the beans until tender, press them through a fine-mesh sieve or a food mill to separate the skins from the soft pulp. Discard the skins. Return the smooth pulp to the pot, add the sugar and salt, and cook until thickened.
- For a Thicker Paste: If you need a firmer paste for fillings like in baked buns, simply cook it a little longer in Step 3 to evaporate more moisture.
How to Use Red Bean Paste
The possibilities are nearly endless! Red bean paste is a staple filling and topping in many Asian cuisines. Here are a few ideas to get you started:
- Mochi: Use it as a classic filling for Daifuku Mochi.
- Steamed Buns (Baozi): Fill soft, fluffy steamed buns for a delicious snack.
- Pastries: Use it in flaky pastries or as a swirl in bread.
- Dessert Topping: It’s a wonderful topping for ice cream, shaved ice, or yogurt. It could even be a unique layer in a no-bake cheesecake.
- Soups: It is the base for a sweet dessert soup called Tang Yuan.
Storage Instructions
Proper storage is essential to keep your homemade red bean paste fresh. Allow the paste to cool completely before storing.

- Freezer: For longer storage, you can freeze it. Portion the paste into desired amounts, wrap tightly in plastic wrap, and place in a freezer-safe bag or container. It will keep well in the freezer for up to 3 months. Thaw it in the refrigerator overnight before using.
