Ingredients
- 1 tablespoon olive oil
- 1 onion, diced
- 2 cloves garlic, minced
- 2 medium sweet potatoes, peeled and cubed
- 2 cans (15 oz each) black beans, drained and rinsed
- 1 can (14 oz) diced tomatoes
- 4 cups vegetable broth
- 1 teaspoon ground cumin
- 1 teaspoon chili powder
- 1/2 teaspoon smoked paprika
- Salt and pepper, to taste
- Fresh cilantro and lime wedges, for serving
Step-by-Step Instructions
1. Sauté the aromatics. Heat olive oil in a large pot over medium heat. Add the onion and cook for 3–4 minutes until softened, then stir in the garlic and cook for 30 seconds more.
2. Add the remaining ingredients. Stir in the sweet potatoes, black beans, diced tomatoes, and vegetable broth. Add the cumin, chili powder, smoked paprika, salt, and pepper.
3. Simmer. Bring the soup to a boil, then reduce heat to low. Cover and simmer for 20–25 minutes, until the sweet potatoes are fork-tender.
4. Adjust the texture (optional). For a thicker soup, use an immersion blender to partially blend the soup, leaving some chunks for texture.
5. Season and serve. Taste and adjust seasoning as needed. Serve hot, garnished with fresh cilantro and a squeeze of lime.
Tips for the Best Sweet Potato Black Bean Soup
- Cut sweet potatoes evenly — uniform pieces cook at the same rate and become tender together.
- Partially blend for creaminess — you don't need a full blend, just a few pulses to thicken the broth.
- Taste before adding extra salt — canned beans and broth both contain sodium, so season gradually.
- Add lime at the end — a squeeze of fresh lime juice brightens the whole dish right before serving.
Recipe Variations
- Spicy Version: Add a diced jalapeño with the onion, or a pinch of cayenne pepper.
- Add Corn: Stir in a cup of corn kernels for extra sweetness and texture.
- Creamy Version: Top with a dollop of sour cream or plain Greek yogurt before serving.
