Step 1: Preheat your oven to 400°F (200°C). Lightly grease a large baking sheet or a 9x13 inch baking dish.
Step 2: In a large oven-safe skillet (or a regular skillet if transferring later) over medium-high heat, add the olive oil. Once hot, add the ground turkey. Break it up with a spoon and cook until browned, about 5-7 minutes. Drain any excess fat.
Step 3: Add the diced onion to the skillet with the cooked turkey and sauté for 3-4 minutes until softened. Stir in the minced garlic and cook for another minute until fragrant.
Step 4: Add the cubed sweet potatoes, diced bell pepper, paprika, cumin, garlic powder, onion powder, salt, and black pepper to the skillet. Stir well to combine, ensuring the sweet potatoes and turkey are evenly coated with the spices.
Step 5: If not using an oven-safe skillet, transfer the entire mixture from the skillet to your prepared baking sheet or dish, spreading it out into an even layer.
Step 6: Bake for 25-30 minutes, or until the sweet potatoes are tender and lightly caramelized. Stir halfway through baking to ensure even cooking and browning. If desired, broil for the last 2-3 minutes for extra crispness, watching carefully to prevent burning.
Step 7: Remove from the oven. Garnish with fresh chopped parsley or cilantro, if desired, and serve immediately.
