Heat a large skillet over medium heat and cook the ground turkey until it is no longer pink, breaking it up with a spoon as it browns. Drain any excess liquid.
Add the cooked turkey to the slow cooker along with the diced sweet potatoes, onion, garlic, and red bell pepper.
Stir in the black beans, diced tomatoes, chicken broth, chili powder, cumin, smoked paprika, salt, and black pepper until everything is evenly combined.
Cover and cook on low for 6 to 7 hours, or until the sweet potatoes are tender.
Taste and adjust salt and pepper if needed. Serve hot with fresh cilantro on top.
