01 - Preheat the oven to 400°F. Lightly grease a 9x13-inch baking dish and set aside.
02 - Heat olive oil in a large skillet over medium heat. Add the ground turkey and cook for 5 to 7 minutes, breaking it apart with a wooden spoon, until evenly browned and no longer pink.
03 - Add the diced onion, red bell pepper, and minced garlic to the skillet. Sauté for 3 to 4 minutes until the vegetables have softened and become fragrant.
04 - Stir in the diced sweet potatoes and cook for an additional 3 minutes, allowing them to begin softening and picking up flavor from the spices.
05 - Pour in the drained black beans, diced tomatoes with their juice, ground cumin, smoked paprika, chili powder, salt, and black pepper. Stir thoroughly to combine all ingredients evenly.
06 - Reduce the heat to medium-low, cover the skillet, and let the mixture simmer for 10 minutes. This allows the spices to meld and the sweet potatoes to begin tenderizing.
07 - Spread the turkey and sweet potato mixture evenly into the prepared 9x13-inch baking dish, pressing it down gently into an even layer.
08 - Cover the dish tightly with aluminum foil and bake for 20 minutes until the sweet potatoes are nearly fork-tender.
09 - Remove the foil and sprinkle the shredded cheese evenly across the top. Return to the oven uncovered and bake for another 10 minutes, or until the cheese is melted and bubbly and the sweet potatoes are fully tender.
10 - Remove from the oven and let rest for 5 minutes. Garnish with freshly chopped cilantro or parsley if desired, then serve hot.
