01 - Wash, peel, and cut the sweet potatoes into 1/2-inch cubes. Finely chop the onion and mince the garlic.
02 - In a large heavy-bottomed pot over medium heat, sauté the chopped onion for 4-5 minutes until softened. Add the minced garlic and cook for 1 minute until fragrant.
03 - Incorporate sweet potato cubes, black beans, diced tomatoes with juices, chili powder, cumin, smoked paprika, salt, black pepper, and vegetable broth. Mix well to combine.
04 - Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 25-30 minutes, stirring occasionally, until the sweet potatoes are fork-tender and flavors meld.
05 - Taste and adjust salt or spices as desired. Ladle chili into bowls and top with optional garnishes such as avocado, cilantro, and lime wedges.
