Ingredients for adzuki bean soup
Simple ingredients transform into a velvety soup with layers of sweet-savory depth.
| Ingredient | Amount | Notes |
|---|---|---|
| Adzuki Beans 🌾 | 1 ½ cups | Dried, soaked overnight |
| Vegetable Broth 💧 | 4 cups | Low-sodium preferred |
| Carrots 🥕 | 1 medium | Peeled, sliced into rounds |
| Daikon Radish 🥕 | 1 medium | Peeled, sliced into rounds |
| Garlic Cloves 🧄 | 4 cloves | Minced for depth |
| Fresh Ginger 🌿 | 1 inch | Thinly sliced |
| Sesame Oil 🫒 | 1 tbsp | Toasted for aroma |
| White Miso Paste 🧂 | 2 tbsp | High-quality preferred |
| Maple Syrup 🍯 | 1 tbsp | For subtle sweetness |
| Soy Sauce 🍶 | 1 tbsp | For umami depth |
| Carrots 🥕 | 1 cup | Peeled, chopped into chunks |

Adzuki beans are the heart of this dish—look for dried beans at specialty stores like Whole Foods or Asian markets for the best texture. Soaking overnight ensures tender, creamy beans without compromise. The miso paste elevates umami, so high-quality white miso is a must. For the ginger and garlic, fresh is non-negotiable—powdered versions lack the aromatic complexity. If you can't find daikon radish, substitute extra carrots for similar texture, though the flavor will differ slightly.
No sesame oil? Toasted sesame seeds in neutral oil work as a substitute, though the aroma won't be identical. Short on maple syrup? Agave nectar or a touch of brown sugar provide comparable sweetness. The soy sauce can be swapped for tamari for gluten-free, but traditional soy sauce delivers the best balance. For the carrots, baby carrots work perfectly—no need to peel them. The green onions are divided: white parts for cooking, green for garnish—don't skip the final garnish, as it adds crucial brightness.
This soup tastes even better the next day as flavors meld. Store in an airtight container in the fridge for up to 5 days. For longer storage, freeze portions for 3 months. The beans soften further when reheated, so add a splash of water if the texture seems too thick. Double the batch—it reheats beautifully and makes an excellent meal prep option.

Step-by-step instructions for adzuki bean soup
This method balances sweetness, umami, and earthy depth for a harmonious soup every time.
Prepare the Base Ingredients
Begin by rinsing the 1.5 cups adzuki beans under cold water to remove any debris. In a large pot, combine the beans with 4 cups vegetable broth and bring to a boil over medium-high heat. Reduce heat to medium-low and simmer for 30 minutes, skimming off any foam that rises to the surface. This ensures a clean, flavorful broth foundation.
While the beans simmer, peel and slice the 1 medium carrot and 1 medium daikon radish into ¼-inch thick rounds. Thinly slice the 1 inch fresh ginger and mince the 4 cloves garlic. Chop the 1 cup carrots into ½-inch chunks and separate the 3 whole green onions into white and green parts. These preparations should be done simultaneously to maintain an efficient workflow.
Build Flavor Layers
After the initial 30 minutes of simmering, add the sliced carrot and daikon radish rounds to the pot. Stir gently to combine, then add the minced garlic and ginger. Cook for an additional 10 minutes until the vegetables begin to soften but remain slightly firm. This step develops the aromatic base without overcooking the vegetables.
Next, stir in the 2 tablespoons white miso paste, 1 tablespoon maple syrup, and 1 tablespoon soy sauce. The miso will dissolve into the broth, creating a rich umami depth, while the maple syrup adds subtle sweetness. Simmer for another 5 minutes to allow the flavors to meld together. Taste the broth at this point—it should be balanced with a touch of sweetness and savory notes.
Finish and Garnish
Add the chopped carrot chunks and the white parts of the 3 whole green onions to the pot. Simmer for 15-20 minutes until the beans are tender but not mushy. The adzuki beans should hold their shape while remaining soft to the bite. If the soup becomes too thick, add a splash of water to reach your desired consistency.
In a small pan, heat the 1 tablespoon sesame oil over low heat until it shimmers. Add the 1 tablespoon sesame seeds and toast them for 1-2 minutes until fragrant and lightly golden. Remove from heat and set aside. Ladle the soup into bowls, garnishing each serving with the toasted sesame seeds and the chopped green parts of the 3 whole green onions. Serve immediately while hot.
Optional Final Touches
For an extra layer of complexity, drizzle a few drops of the toasted sesame oil over each bowl before serving. This not only enhances the visual appeal but also adds a nutty aroma that complements the soup's earthy and sweet-savory profile. The soup should have a vibrant color with the bright green of the garnishes contrasting beautifully against the creamy bean broth.
This method ensures a well-balanced soup with tender beans, vibrant vegetables, and a harmonious blend of flavors. The key is patience in simmering and attention to the balance of sweet, savory, and umami notes. Adjust the seasoning to taste, but the initial measurements should provide a solid foundation for a delicious result.
Pro Tips For Making Adzuki Bean Soup
- SOAK BEANS OVERNIGHT: I used to skip this and wonder why my soup turned out grainy—adzuki beans need at least 8 hours soaking, ideally in cold water with a pinch of salt. Drain and rinse before cooking to cut down on prep time later, but don’t skip the soak unless you’re okay with a longer simmer (and potential texture issues).
- PEEL DAIKON THIN: Daikon’s skin can make the broth cloudy, but peeling it too aggressively wastes good real estate. Use a vegetable peeler to shave off just the outer layer—thin, even slices cook faster and keep the soup cleaner without losing flavor.
- SIMMER LOW AFTER BOIL: After the beans hit a rolling boil, drop the heat to a gentle simmer—too much heat splits the beans and turns the broth into a gluey mess. A slow simmer (just bubbles breaking the surface) keeps them intact and lets the broth develop depth.
- GARLIC: MINCE FINE: Whole cloves or rough chops? You’ll taste them long after the soup’s done. Mince the garlic into tiny pieces so it dissolves completely—no one wants a surprise bite of raw garlic in an otherwise smooth broth. (Yes, even if you’re impatient like me.)
Regional styles of this adzuki bean soup
Japanese Anko-Inspired
In Japan, adzuki beans are often sweetened and blended into anko, a smooth red paste used in desserts like mochi and dorayaki. For a dessert-inspired twist, simmer the beans with ½ cup sugar and 1 cup water until ultra-soft, then blend into a thick paste.
Stir this into your soup at the end for a naturally sweetened, velvety texture. Garnish with crushed mochi bits for an authentic touch. 🌸
Korean Tangsu Style
Korean tangsu features sweetened red beans, similar to anko but with a lighter texture. After simmering the beans, add 1 tbsp honey and ½ tsp cinnamon to the broth for warmth.
Serve the soup over steamed rice and top with a fried egg for a Korean-inspired fusion. The cinnamon adds subtle spice that balances the beans' natural sweetness. 🌶️
Chinese Sweet-Savory
Chinese versions often include star anise and goji berries for depth. After adding the miso and soy sauce, stir in 1 star anise pod and 1 tbsp goji berries (soaked in warm water first).
Simmer for 5 minutes to infuse the broth with aromatic notes. Remove the star anise before serving. The goji berries add chewy texture and a hint of tartness. 🌿
Thai Coconut Twist
For a Thai-inspired version, replace the vegetable broth with 4 cups coconut milk and add 1 tbsp red curry paste after the initial simmer. Finish with 1 tsp lime juice and fresh cilantro.
The coconut milk creates a creamy, tropical base that pairs beautifully with the earthy beans. Serve with jasmine rice for a complete meal. 🥥
Mexican-Inspired Spicy
Add a Mexican flair by incorporating 1 tbsp chipotle powder and ½ tsp cumin with the miso and soy sauce. Top with crumbled cotija cheese and avocado slices for a fusion of textures.
The smoky chipotle balances the beans' sweetness while cumin adds warmth. Perfect for those who enjoy a little heat! 🌶️
Modern Western Adaptation
For a Western-friendly version, swap the miso for 1 tbsp nutritional yeast and add ½ tsp smoked paprika for depth. Use chicken or vegetable broth and finish with a drizzle of olive oil and fresh parsley.
This version keeps the bean's natural sweetness while offering a familiar flavor profile. Ideal for those new to Asian-inspired dishes! 🌱

Frequently asked questions
Why do I need to soak adzuki beans overnight?
Soaking overnight (8-12 hours) dramatically reduces cooking time and ensures tender, creamy beans without losing their shape. The beans absorb water and soften, allowing them to cook evenly in just 1.5 hours instead of 3-4 hours if unsoaked. This step also removes excess starch that can make the soup too thick.
Can I use canned adzuki beans instead of dried?
Yes, but with adjustments! Use 1 (15 oz) can of drained beans and reduce the broth to 3 cups to maintain balance. Simmer for only 10-15 minutes after adding vegetables to avoid mushy texture. Canned beans are pre-cooked, so over-simmering destroys their structure.
How can I make this soup creamier without dairy?
Blend ½ cup cooked beans with ¼ cup broth until smooth, then stir back into the pot. For extra richness, add 1 tbsp coconut cream or 1 mashed potato (cooked in broth) for a velvety texture. The miso paste also naturally thickens the soup as it simmers.
What's the best way to store leftovers?
Let the soup cool completely, then transfer to an airtight container. It keeps for 5 days in the fridge or 3 months in the freezer. Reheat gently on low heat, adding a splash of water if it thickens too much. The flavors actually deepen overnight!
Can I make this in a pressure cooker?
After soaking, combine beans, broth, and aromatics in your pressure cooker. Cook on high pressure for 15 minutes, then release naturally. Add vegetables and seasonings in the final 10 minutes of cooking. This cuts total time to about 30 minutes while keeping all the depth of flavor.
