Ingredients for black soybean chili

Fermented black soybeans and crispy black bean topping—this chili delivers restaurant-quality depth with minimal effort.

The fermented black soybeans are the star here—Asian markets or specialty grocers carry them dried, but you can find them pre-soaked at Whole Foods if you're short on time. Look for beans with a deep, almost meaty aroma (not musty or sour). Soaking overnight isn't optional—it unlocks that earthy, nutty depth that store-bought versions miss. For the crispy topping, canned black beans work perfectly, but if you want extra crunch, use dried beans soaked overnight too. The shiitake mushrooms add umami without overpowering—fresh is ideal, but dried rehydrated works in a pinch. Sweet potatoes should be firm with no soft spots, and orange-fleshed varieties hold up best during long cooking.

No fermented black soybeans? Miso paste or soy sauce can add umami depth, but you'll lose that funky complexity. Running out of shiitake? Cremini or oyster mushrooms work in a bind. The chili paste can be swapped for gochujang or sambal oelek for different heat levels. For the crispy topping, if you skip the coconut oil, avocado oil or neutral oil works just as well. The maple syrup balances the earthiness—agave or brown sugar are fine substitutes. And if you're missing smoked paprika, liquid smoke at half the amount gives a similar smoky kick. Always taste as you go—this chili builds flavor over time, so don't be afraid to adjust salt or acidity along the way.

This chili tastes even better the next day as flavors meld—portion into containers for easy reheating. Store in the fridge for 5-6 days or freeze for 3 months. The crispy black bean topping stays crunchy for 2 days if stored separately in an airtight container. For meal prep, double the batch and freeze half—just thaw overnight in the fridge before reheating. The broth reduces slightly when reheated, so add a splash of water if it gets too thick. And if you're serving a crowd, make the crispy topping in batches—it burns fast in large quantities.

Step-by-step instructions for black soybean chili

Here's how to build a chili with deep umami layers and that signature crispy black bean topping.

Heat the 1 tbsp coconut oil in a large Dutch oven over medium-high heat until shimmering. Add the 1 large diced onion and cook for 4-5 minutes until softened and translucent. Stir in the 6 minced garlic cloves and 1 tbsp grated fresh ginger, cooking for 30 seconds until fragrant—this prevents the garlic from burning.

Add the 1.5 cups drained fermented black soybeans and 2 tbsp red chili paste, stirring constantly for 2 minutes until the soybeans begin to soften. Pour in 4 cups vegetable broth and scrape up any browned bits from the bottom—this captures all the flavor. Bring to a gentle simmer and let cook uncovered for 10 minutes to develop the base.

While the base simmers, peel and cube the 2 medium sweet potatoes into 1.5-inch pieces. Add them to the pot along with the 8 sliced shiitake mushrooms. Stir gently to combine, then reduce heat to medium-low and let cook for 15-18 minutes until the sweet potatoes are tender when pierced with a fork but still hold their shape.

Here's the thing—you want the sweet potatoes to stay slightly firm so they don't turn to mush in the final chili. If they're cooking too fast, reduce heat slightly. The mushrooms should release their moisture and become tender but still hold their form.

Increase heat to medium and stir in the 2 tbsp tomato paste, 1 tbsp maple syrup, 1 tsp smoked paprika, 1 tsp cumin, and 1.5 tsp sea salt. Let the mixture cook for 3-4 minutes until slightly thickened. Add the 1 can drained black beans and 1 tbsp black soy sauce, stirring well to distribute.

Taste and adjust seasoning—this is where the chili comes together. You want a balance of sweetness from the maple syrup, heat from the chili paste, and umami from the fermented soybeans. If it needs more depth, add another splash of black soy sauce. Let the chili simmer uncovered for 10 minutes to meld all the flavors.

While the chili simmers, prepare the crispy topping. Heat 1 tsp sesame oil in a small skillet over medium-high heat. Add about ½ cup of the drained black beans (reserve the rest for the chili) and cook for 4-5 minutes, stirring occasionally, until they develop a deep golden-brown crust and smell nutty.

Transfer the crispy beans to a paper towel-lined plate to drain excess oil. If they're not crispy enough, return them to the skillet for another 30 seconds. This topping is what makes this chili special—it adds crunch and concentrated bean flavor.

Return the chili to a gentle simmer and cook for another 5 minutes to let the flavors fully develop. Taste one last time and adjust seasoning if needed. Ladle the chili into bowls, then top generously with the crispy black beans. Drizzle with any remaining sesame oil from the skillet for extra richness.

Serve immediately with a dollop of yogurt or a sprinkle of fresh cilantro if you like. The contrast between the tender chili and crispy topping is what makes this dish unforgettable. Each bite should deliver layers of umami, sweetness, and that satisfying crunch.

Pro cooking tips for this dish

Fermented Bean Magic

The key to unlocking the deep umami flavor in this chili starts with the fermented black soybeans. I can't stress enough how important that overnight soak is—it transforms the beans from bland to funky and complex.

If you're short on time, try soaking them for at least 6 hours instead, but trust me, the longer they soak, the better the flavor.

For the crispy topping, I like to use canned black beans because they're already tender and cook up faster, but dried beans work too if you give them extra time to crisp. 🌱

Pot Control Matters

Using a Dutch oven is my secret weapon for this recipe—it distributes heat evenly and prevents burning. When simmering the chili, keep the heat at medium-low to avoid a skin forming on top.

If you notice the sweet potatoes cooking too quickly, reduce the heat slightly or add a splash of water to maintain a gentle simmer. The goal is to develop those flavors without breaking down the texture of your ingredients. ⏰

Layering Flavors

This chili builds flavor in stages, so don't rush it. After adding the tomato paste and spices, let everything cook for 3-4 minutes to let those flavors meld together. Taste as you go—I usually add a little more black soy sauce or maple syrup if the chili needs more depth.

The smoked paprika and cumin add warmth, but if you want extra smokiness, a pinch of liquid smoke (about ½ teaspoon) works in a pinch. 🔥

Crispy Topping Secrets

The crispy black bean topping is what makes this chili special, so don't skimp on the oil. Use sesame oil for that nutty aroma, but if you're out, avocado oil works just as well. Cook the beans in batches if needed—they burn fast!

For extra crunch, I like to press them gently with a spatula while cooking. Once they're golden and smell toasty, transfer them to a paper towel-lined plate immediately to drain excess oil. This keeps them crispy for longer. 💫

Simmering to Perfection

Let the chili simmer uncovered for the final 10 minutes—this allows the broth to reduce slightly and the flavors to deepen. If it gets too thick, add a splash of water or broth.

The sweet potatoes should be tender but still hold their shape, and the mushrooms should be soft with a slight chew. Taste one last time before serving—this is your chance to balance the flavors perfectly. 💡

Serving with Style

Serve the chili immediately with the crispy black beans on top—this contrast in textures is what makes it unforgettable. For extra richness, drizzle with any leftover sesame oil from the skillet.

If you're serving a crowd, make the crispy topping in batches and keep it warm in a 200°F oven until ready to serve. The chili tastes even better the next day, so double the batch and store leftovers in the fridge for up to 5 days. 🌟
