Salads
This adzuki bean salad recipe transforms humble beans into a vibrant, textured dish that bridges Japanese tsukudani traditions with modern bold flavors. The secret lies in balancing sweet soy-mirin dressing with crisp toppings—think sesame seeds and thinly sliced cucumber—that add crunch with every bite.
I developed this version after realizing how versatile adzuki beans could be beyond desserts, and the result is a salad that shines as a side or even as a sushi roll filling.
The preparation is straightforward but precise: properly rinsing and draining the beans removes excess starch, while thinly slicing vegetables ensures even texture. A quick marinade of soy sauce, sesame oil, and rice vinegar infuses the beans with umami depth, while a sprinkle of toasted sesame seeds adds nutty warmth.
What makes this recipe stand out is how it maintains that perfect sweet-savory balance—no bitterness, no cloying sweetness—just a harmonious bite that lingers.
What you'll end up with is a colorful, protein-packed salad that's as satisfying as it is visually appealing. The beans stay tender yet hold their shape, the dressing clings without making them soggy, and the toppings add layers of texture.
This isn't just another bean salad—it's a complete dish that works as a standalone meal or pairs beautifully with grilled fish, rice bowls, or even as a sushi roll filling.
For extra flair, consider adding a drizzle of spicy mayo or a squeeze of citrus to brighten the flavors. The possibilities are endless, but the foundation remains the same: simple techniques that deliver restaurant-quality results. Let's get started on creating this versatile, crowd-pleasing salad.

| Sesame Oil 🫒 | 1 tsp | For extra toasted flavor |

Adzuki beans are the heart of this dish, so choose canned varieties without added salt—rinsing removes excess starch for better texture. Trader Joe's and Asian grocery stores carry high-quality, pre-cooked beans that stay tender. For extra flavor, look for beans labeled 'sweet' or 'for desserts'—they're often firmer and hold shape better. Toasting the sesame seeds in a dry pan for 2-3 minutes until fragrant (watch closely—they burn fast!) adds depth that store-bought pre-toasted seeds can't match.
No sesame oil? Avocado oil or neutral vegetable oil works in a pinch, though the toasted nutty flavor is key. Substitute mirin with a mix of white wine and sugar (1 tsp per tbsp wine). The cucumber should be crisp—English cucumbers stay crunchy longer than seedless varieties. For extra crunch, add thinly sliced jicama or shredded carrots. The dressing ratio is precise: too much vinegar makes it sharp, too little soy sauce leaves it bland. Taste as you go, adjusting with 1 tsp soy sauce or 1/2 tsp sugar at a time.
Store undressed beans in the fridge for 3 days—dress them just before serving to keep crunch. Toasted sesame seeds lose flavor after 1 week, so store them in an airtight container away from light. For meal prep, portion the dressing separately and toss just before eating. This salad reheats beautifully—30 seconds in the microwave revives its texture. Double the batch: it's perfect for lunchboxes or potlucks.

Step-by-step instructions for adzuki bean salad
Assemble this harmonious salad with precise technique for perfect texture and flavor balance.
Prepare the Bean Base
Drain and rinse the 1.5 cups adzuki beans thoroughly under cold water to remove excess starch. This prevents the salad from becoming gummy. Transfer the beans to a mixing bowl and set aside.
In a small bowl, whisk together the 3 tablespoons rice vinegar, 2 tablespoons soy sauce, 1 tablespoon mirin, 1 tablespoon sesame oil, 1 tablespoon lemon juice, 0.5 teaspoon salt, and 0.25 teaspoon black pepper. Pour this dressing over the beans and toss gently but thoroughly to coat each bean evenly. Let the mixture marinate at room temperature for 15 minutes—this allows the flavors to meld and the beans to absorb the dressing completely.
Prep and Combine Vegetables
Peel and thinly slice the whole English cucumber lengthwise, then cut into ¼-inch thick half-moons. Remove any remaining seeds to prevent a watery salad. Finely dice the 0.5 cup red bell pepper and thinly slice the 0.25 cup red onion. Transfer these vegetables to the bowl with the marinated beans.
Gently fold the vegetables into the bean mixture using a spatula, being careful not to crush the beans. The goal is to distribute the vegetables evenly while maintaining the integrity of each component. Taste the mixture and adjust seasoning if needed—you may want to add a splash more rice vinegar for brightness or a pinch of salt for balance.
Toast the Sesame Seeds
In a dry skillet over medium-low heat, toast the 2 tablespoons sesame seeds for 2-3 minutes, stirring constantly until they turn a rich golden brown and release their nutty aroma. This step is crucial—raw sesame seeds won't provide that satisfying crunch and toasted flavor. Transfer the toasted seeds to a small bowl and let them cool slightly before using.
Assemble and Garnish
Divide the bean and vegetable mixture evenly among 4 serving bowls. Drizzle each portion with 1 teaspoon toasted sesame oil (the extra amount from your ingredients list) and sprinkle with the toasted sesame seeds. For an optional garnish, dollop 2 tablespoons spicy mayo in the center of each serving or drizzle it artistically over the top.
Serve immediately while the vegetables retain their crisp texture. The salad's sweet-savory balance comes from the adzuki beans' natural sweetness, the tangy rice vinegar, and the umami depth of soy sauce and mirin. The toasted sesame seeds add the perfect crunchy contrast to every bite.
Pro Tips For Making Adzuki Bean Salad
- SOAK BEANS OVERNIGHT: I learned this the hard way—rushing adzuki beans with a 30-minute soak leaves them tough and uneven. Double the cooking time if you skip this, and even then, they’ll still feel like rubber. Just toss them in water at night, cover, and wake up to beans that soften perfectly.
- PEEL CUCUMBER LIKE A PRO: That thick, bitter skin on English cucumbers is the worst. Instead of peeling in strips (which wastes good flesh), use a vegetable peeler to shave off just the outer layer—like you’re giving it a haircut, not a full strip job. You’ll save time and keep the crunch.
- SWEAT ONIONS FIRST: Raw red onion in this salad? It’ll just make your eyes water and dominate the flavor. Sauté thin slices in a dry pan for 2-3 minutes until translucent—just enough to mellow the bite. Then toss them in ice water to stop cooking. Trust me, your salad will thank you.
- TOSS SESAME LAST: Toasting sesame seeds separately is overrated for this dish. Sprinkle them raw over the salad right before serving—it keeps them crisp and prevents them from turning into a sad, oily paste. Plus, you avoid the risk of burning them (yes, I’ve done that too).
Storing and reheating this adzuki bean salad
Fridge Storage Tips
Store your adzuki bean salad in an airtight container with a lid for up to 3 days in the refrigerator. The dressing helps preserve the beans' texture, but I always recommend storing the dressing separately if you're prepping ahead.
This way, you can toss the beans with fresh dressing just before serving to maintain that perfect crunch. 🥬
Freezer Prep
This salad freezes surprisingly well for up to 2 months if you focus on the beans and dressing separately. Spread the marinated beans on a tray, freeze until solid, then transfer to a freezer bag with parchment paper between layers.
When ready to eat, thaw overnight in the fridge and toss with fresh vegetables and dressing. The texture won't be as crisp, but the flavor stays intact!
Reheating Methods
For a quick lunch, microwave individual portions covered with a damp paper towel for 30-45 seconds on medium power. Stir halfway through to redistribute the moisture. If reheating in a pot, use low heat with 1 tablespoon water or broth to prevent sticking.
The beans absorb liquid quickly, so keep an eye on them to avoid a mushy texture. 🔥
Crunch Revival
If your salad loses its crunch after refrigeration, revive it by tossing with 1 teaspoon toasted sesame oil and a pinch of salt. The oil helps restore that satisfying bite. For extra crunch, add fresh toppings like thinly sliced cucumber or a sprinkle of toasted sesame seeds right before serving.
I also love a squeeze of fresh lemon juice to brighten things up!
Meal Prep Strategy
Double the recipe and store components separately for easy assembly. Keep the beans and dressing in one container, and store vegetables and toppings in another. This way, you can customize each serving—add spicy mayo for heat, or keep it classic with sesame seeds.
Portion into mason jars for grab-and-go lunches, with dressing at the bottom and toppings on top. Just shake and enjoy! ⏰

Frequently asked questions
Why do I need to rinse the adzuki beans before using them?
Rinsing removes excess starch from canned beans that can make your salad gummy. The 1.5 cups of beans will maintain their shape and texture better when properly drained. This step is especially important if you're using low-sodium beans, as they often contain added starch to improve texture.
Can I use dried adzuki beans instead of canned?
Yes, but you'll need to soak them first! Soak 1 cup dried beans overnight, then cook until tender (about 1-1.5 hours). Dried beans have a nuttier flavor and firmer texture, but they require more prep time. For this recipe, canned beans are more convenient and yield consistent results.
How do I prevent the cucumber from making the salad watery?
Remove all cucumber seeds and slice it thinly against the grain. Pat the slices dry with a paper towel before adding them to the salad. English cucumbers stay crunchier longer than seedless varieties. If your salad still seems watery, drain excess liquid after mixing and let it sit for 5 minutes before serving.
What can I substitute if I don't have mirin?
Mix 1 tablespoon white wine or rice vinegar with 1 teaspoon sugar to mimic mirin's sweetness and acidity. For a non-alcoholic option, use 1 tablespoon honey or agave with 1 tablespoon rice vinegar. The dressing will still taste balanced, though mirin's unique umami depth is hard to replicate perfectly.
Is this salad gluten-free?
Only if you use gluten-free soy sauce and rice vinegar. Check labels—many regular soy sauces contain wheat. For a fully gluten-free version, substitute with tamari or a dedicated gluten-free soy sauce. The rest of the ingredients are naturally gluten-free, making this a great option for those avoiding gluten.
