In a large pot, heat the olive oil over medium heat. Add the chopped onion and sauté for about 3-4 minutes until translucent.
Stir in the minced garlic and diced red bell pepper, cooking for an additional 2-3 minutes until fragrant.
Add the diced sweet potatoes to the pot and stir to combine. Cook for 5 minutes, allowing them to slightly soften.
Sprinkle in the cumin, smoked paprika, chili powder, and cayenne pepper, stirring well to coat the veggies. Cook for another minute to toast the spices.
Pour in the vegetable broth and add the diced tomatoes and black beans to the pot. Stir to combine everything and bring to a boil.
Reduce the heat to low, cover the pot, and let it simmer for 25-30 minutes or until the sweet potatoes are fork-tender.
Taste and season with salt and pepper as needed. If you prefer a thicker chili, mash some of the sweet potatoes against the pot with the back of a spoon.
Serve hot, garnished with fresh cilantro.
Notes
Adjust the cayenne pepper to taste for desired spiciness.
