01 - Heat a large pot or Dutch oven over medium heat. Add ground turkey and cook, breaking it up with a spoon, until browned and cooked through, about 5-6 minutes. Drain excess fat if needed.
02 - Add the onion, bell pepper, jalapeño, and garlic to the pot. Cook, stirring occasionally, until vegetables are softened, about 4-5 minutes.
03 - Stir in chili powder, cumin, smoked paprika, oregano, salt, black pepper, and cayenne. Cook for 1 minute to toast the spices and release their flavors.
04 - Add diced tomatoes, kidney beans, black beans, and chicken broth. Stir well to combine all ingredients.
05 - Bring the mixture to a boil, then reduce heat to low and simmer uncovered for 25-30 minutes, stirring occasionally, until thickened and flavors meld together.
06 - Taste the chili and adjust salt, pepper, or spices as needed to achieve desired flavor balance.
07 - Ladle chili into bowls. Top with cheddar cheese, cilantro, and sour cream if desired. Serve hot with crackers on the side for dipping.
