Healthy Homemade Red Bean Paste (Anko)
A smooth, naturally sweet paste made from azuki beans with a deep, earthy flavor. This homemade version skips the heavy syrups and lets the beans shine with just a touch of sugar. Perfect for filling mochi, dorayaki, or spreading on toast.
For 8 servings
- prep
Soak the azuki beans overnight.
Place the rinsed azuki beans in a bowl, cover with plenty of water, and let them soak for at least 8 hours or overnight. The beans will double in size.
TIPSoaking reduces cooking time and helps the beans cook evenly. - boil · ~60 min
Boil the beans until tender.
1.Drain the soaked beans and add them to a saucepan with 750 ml fresh water.2.Bring to a rolling boil over high heat, then reduce to a low simmer.3.Skim off any foam that rises to the surface.4.Cook for 50-60 minutes until the beans are completely soft and crush easily between your fingers.TIPAdd a splash of cold water if the pot boils dry before the beans are tender—this shocks the beans and helps them soften. - saute · ~10 min
Mash and sweeten the bean paste.
1.Drain the cooked beans, reserving a few tablespoons of the cooking liquid. Return the beans to the saucepan.2.Add the sugar and a pinch of salt to the warm beans.3.Mash the mixture with a wooden spoon or potato masher over low heat, stirring continuously.4.Cook for 5-10 minutes, adding a splash of reserved cooking liquid if the paste becomes too dry. It should be thick enough to hold its shape but still spreadable.TIPFor a completely smooth paste (koshian), press the cooked beans through a fine mesh strainer before adding sugar. - rest
Cool the paste completely.
Transfer the paste to a bowl and let it cool to room temperature. It will thicken further as it cools.
TIPThe paste can be stored in an airtight container in the fridge for up to a week, or frozen for a month.
What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1For a smoother paste (koshian), pass the cooked beans through a fine-mesh strainer before adding sugar.
- 2Reserve the bean cooking liquid — a splash loosens the paste without diluting the bean flavor.
- 3Don't skip the pinch of salt; it balances sweetness and deepens the earthy azuki taste.
- 4Cook the paste over low heat while stirring constantly to prevent scorching and ensure even drying.
- 5Cool the paste completely before covering; condensation can make it watery and shorten fridge life.
Adapt it for your goals.
Less-sweet
Reduce sugar to 70 g for a more savory paste that pairs beautifully with mochi or as a filling for steamed buns.
smooth vs chunkySmooth vs chunky
For a chunky paste (tsubuan), stop mashing once half the beans are broken; for entirely smooth (koshian), press the cooked beans through a fine sieve before sweetening.
matcha infusedMatcha-infused
Whisk 1 teaspoon of matcha powder into the hot paste after mashing for a bright green tea twist that complements the azuki.
