Heat olive oil in a large pot over medium-high heat. Add the onion, garlic, and red bell pepper. Sauté for 5–7 minutes, stirring often, until the vegetables are softened.
Add the ground turkey and break it apart with a spoon. Cook until fully browned and no longer pink.
Stir in chili powder, cumin, oregano, cayenne pepper, and salt. Cook for 20 seconds to bloom the spices.
Add the tomatoes, chicken broth, kidney beans, and corn. Stir well and bring the mixture to a boil.
Reduce heat to low and let the chili simmer uncovered for 30–45 minutes, stirring occasionally, until thickened and flavorful.
Taste and adjust seasonings as needed.
Serve hot with your choice of optional toppings.
Notes
Use less chili powder (2–3 tablespoons) if your brand is spicier than McCormick’s.
For a slow cooker version: use ½ cup broth, brown the turkey and onion first, then cook everything in a slow cooker on high for 3–4 hours or low for 6–7 hours.
