The adzuki beans are the star—soaking them overnight cuts cooking time dramatically. Trader Joe's has the best dried adzuki beans, but any organic brand works. Shiitake mushrooms add that meaty umami without meat, and fresh is best—dried ones need rehydrating. The tofu? Extra-firm holds up to the long simmer. I always grab mine from the bulk section at Whole Foods—it’s cheaper and fresher. For the broth, low-sodium is key so you control the saltiness.
No shiitake mushrooms? Cremini or oyster mushrooms work in a pinch, but they won’t have the same depth. Fresh ginger and garlic are non-negotiable—dried won’t give that bright punch. Short on time? Pre-minced garlic from the jar saves 5 minutes. The soy sauce can be swapped for coconut aminos if you’re avoiding gluten. And if you’re feeling fancy, miso paste adds another layer of complexity—just a teaspoon at the end. The maple syrup balances the savory notes perfectly, but agave or brown sugar work too.
This soup tastes even better the next day—flavors meld like magic. Store in the fridge for 4-5 days or freeze for 3 months. I always make a double batch because it’s that good. For meal prep, portion into containers with a little broth on top to keep the beans from drying out. Garnish with sesame seeds and green onions right before serving—freshness matters.
Why You'll Love This Recipe
- No-Chop Needed: I swear, the mushrooms just slice themselves—no knife skills required. Toss in pre-sliced shiitake and a block of tofu to cube, and you’re done. Even my "I-can’t-find-a-knife" days work here.
- Umami Bomb: That ginger? Thinly sliced, not chopped—it infuses the broth like a secret weapon. The adzuki beans soften into something almost buttery, while the tofu soaks up the savory depth like a sponge. Honestly, it’s the kind of flavor that makes you pause mid-sip.
- Lunchbox Hero: Between us, this soup reheats perfectly—no soggy tofu, no bland broth. Pack it in jars the night before, and you’ve got a protein-packed lunch that even my picky-eating coworker won’t complain about. (Yes, even on a Tuesday.)
- Pantry Magic: I’ve made this with dried beans and canned—both work, no judgment. Vegetable broth stretches forever, and shiitake mushrooms last ages in the freezer. It’s the kind of recipe that turns $5 worth of ingredients into three meals without breaking a sweat. Budget-friendly? More like budget genius.
Step-by-step instructions for adzuki beans soup
Here's how to create this velvety, sweet-savory soup that balances earthy mushrooms and tender tofu perfectly.
Prepare the Beans and Aromatics
Drain and rinse the soaked 1.5 cups Adzuki Beans thoroughly under cold water. In a large pot, combine the beans with the 6 cups Vegetable Broth and bring to a boil over medium-high heat. Reduce heat to medium-low and simmer for 15 minutes until the beans begin to soften.
While the beans simmer, prepare the aromatics. In a separate bowl, combine the 2 medium Carrots (peeled and sliced), 1 whole Onion (diced), 2 tbsp Fresh Ginger (grated), and 4 cloves Garlic Cloves (minced). Set aside until needed. This prep ensures everything is ready when you're ready to build flavor layers.
Build the Sweet-Savory Base
Add the prepared aromatics to the simmering beans and broth. Stir gently to combine, then add the 8 oz Shiitake Mushrooms (sliced if fresh or rehydrated). Increase heat to medium and bring the mixture to a gentle boil. Reduce heat to low and let it simmer uncovered for 20 minutes, stirring occasionally.
After 15 minutes of simmering, add the 2 tbsp Soy Sauce and 1 tbsp Maple Syrup. Stir well to distribute the flavors evenly. The soy sauce adds umami depth while the maple syrup creates that signature sweetness that balances the savory elements. Taste the broth at this point—it should be developing rich, complex flavors.
Add Tofu and Final Seasonings
Cut the 1 block Firm Tofu into ½-inch cubes and add them to the pot. Increase heat to medium and simmer for an additional 10 minutes, allowing the tofu to absorb the flavorful broth. The tofu should be heated through but still hold its shape.
Season the soup with 1 tsp Sea Salt and 0.5 tsp Black Pepper. Taste and adjust the seasoning if needed—you want a balance of sweet, savory, and umami. The salt enhances all the flavors while the pepper adds a subtle warmth. The soup should be rich but not overpowering at this stage.
Finish with Toasted Sesame Oil and Garnishes
Remove the pot from heat and stir in 1 tbsp Sesame Oil. This final touch adds a nutty aroma and depth of flavor that ties everything together. Let the soup sit for 5 minutes off the heat to allow the sesame oil to infuse fully.
Ladle the soup into bowls and garnish each serving with 0.25 cup Green Onions (sliced) and 1 tbsp Sesame Seeds (toasted). The green onions add a fresh contrast to the rich broth, while the sesame seeds provide texture and a final nutty note. Serve immediately while the tofu is still warm and the broth maintains its silky texture.
Pro Tips For Making Adzuki Bean Soup
- SOAK BEANS OVERNIGHT: If you’re short on time, at least give them a 4-hour soak in warm water—this cuts cooking time by half. I used to skip it and end up with split beans or a mushy texture, so don’t rush this step.
- SLICE SHIITAKES THIN: Thin slices (about 1/8-inch) cook faster and soak up the broth better than thick chunks. Use a sharp knife—dull blades crush them, and that turns your soup into mush.
- SIMMER TOFU LOW: Firm tofu holds up best when simmered gently—drop it in when the broth is just below a boil, or it’ll fall apart. I learned this after watching mine disintegrate into a sad, watery blob.
- SALT THE BROTH LAST: Add salt only after the beans are tender—otherwise, you’ll over-salt the broth while waiting for them to soften. A pinch of ginger and a splash of soy sauce at the end makes all the difference.
Regional styles of this adzuki bean soup
Japanese Anko-Inspired
The Japanese version of adzuki bean soup often features a thicker, slightly sweetened broth that's closer to a stew. In Japan, this style is called anko—a sweet red bean paste—where the beans are simmered until they burst, creating a naturally sweet, jam-like consistency.
For this regional take, reduce the broth by half after adding the beans, then stir in 1 tbsp honey or mirin to enhance the sweetness. Serve it with steamed rice and a drizzle of white miso soup on the side for an authentic Japanese meal. 🍜
Korean Kongnamul Guk
In Korea, adzuki beans are often used in a lighter, broth-based soup called kongnamul guk. This version skips the tofu and focuses on the beans' natural sweetness, paired with a clear, ginger-infused broth.
To adapt this style, reduce the soy sauce to 1 tbsp and add 1 tsp gochugaru (Korean red pepper flakes) for a subtle heat. Include 1 cup spinach or bok choy at the end for a fresh, vibrant touch.
Garnish with sesame seeds and a sprinkle of toasted sesame oil for that signature Korean flavor. 🌶️
Thai-Inspired Spicy Twist
Thai cuisine loves to balance sweet and spicy, so this version adds a kick with 1 tbsp Thai red curry paste and 1 stalk lemongrass (bruised) to the broth. Simmer the beans with these additions for 10 minutes before adding the mushrooms and tofu.
Finish with 1 tsp lime juice and fresh cilantro for brightness. The result is a fragrant, aromatic soup that’s both comforting and exciting. 🌿
Chinese Sweet Bean Soup
In Chinese cuisine, adzuki beans are often simmered in a light, slightly sweet broth with a touch of rock sugar or brown sugar. For this version, replace the maple syrup with 1 tbsp brown sugar and add 1 star anise pod and 1 cinnamon stick while simmering the beans.
The spices infuse the broth with warmth, making it perfect for colder months. Serve with a side of steamed dumplings or congee for a hearty meal. 🍯
Modern Fusion Adaptation
For a contemporary twist, blend ½ cup coconut milk into the finished soup for a creamy texture. Add ½ cup diced bell peppers and 1 tsp smoked paprika for depth, then garnish with crumbled tempeh and avocado slices.
This fusion version keeps the soul of the traditional soup while adding a fresh, modern flair. Perfect for those who love bold flavors with a vegan twist. 🌱

Frequently asked questions
Can I use canned adzuki beans instead of dried?
Yes, but adjust the cooking time! Canned beans are pre-cooked, so simply add them directly to the simmering broth after 10 minutes of cooking (instead of soaking overnight). Reduce the simmering time to 15-20 minutes total to avoid mushy texture. Drain and rinse well first to remove excess sodium.
Why does my adzuki bean soup taste bitter?
Bitterness usually comes from overcooking the beans or using too much soy sauce. Reduce the soy sauce to 1 tbsp and simmer the beans for no longer than 30 minutes total. For extra sweetness, add ½ tsp vanilla extract or 1 tbsp brown sugar at the end. Always taste as you go!
How do I make this soup gluten-free?
Swap the soy sauce for 2 tbsp tamari or coconut aminos and use gluten-free vegetable broth. For extra umami, add 1 tsp nutritional yeast or ½ cup mushrooms (like shiitake or oyster). All other ingredients are naturally gluten-free!
Can I make this soup in an Instant Pot?
Sauté the aromatics for 2 minutes, then add all ingredients (except sesame oil and garnishes) and cook on High Pressure for 8 minutes. Quick-release the pressure, stir in sesame oil, and let sit for 5 minutes before serving. The texture will be slightly different but still delicious!
What’s the best way to reheat leftovers?
Reheat gently on the stove over low heat for 5-7 minutes, stirring occasionally. Avoid microwaving—it can make the tofu rubbery. For extra creaminess, add 1 tbsp coconut milk while reheating. Store in the fridge for 4-5 days or freeze for 3 months.
