Heat your large pot over medium heat and add a splash of olive oil. Sauté the finely chopped onion until it becomes translucent and fragrant, about 3-4 minutes.
Add the minced garlic to the pot and cook for another minute until it releases a warm, aromatic smell.
Push the sautéed onions and garlic to the sides of the pot, then add the ground turkey. Break it apart with your spoon and cook until it browns evenly, about 5-7 minutes, until no pink remains.
Sprinkle in the cumin, smoked paprika, chili powder, and a pinch of salt and pepper. Stir well to coat the turkey and release the spices' fragrant aroma.
Pour in the diced tomatoes and add the tomato paste, stirring to combine everything into a thick, bubbling mixture.
Pour in the broth and stir again, loosening any bits stuck to the bottom of the pot for extra flavor.
Add the chopped bell peppers, diced carrots, and corn kernels, mixing them into the chili base.
Stir in the drained kidney beans, ensuring they are well distributed throughout the mixture.
Reduce the heat to low, cover the pot partially, and let the chili simmer gently for 30 to 45 minutes, stirring occasionally. The chili will thicken, and the flavors will meld beautifully.
Taste the chili and adjust seasoning if needed—add a squeeze of lime or fresh cilantro for brightness if desired.
Serve the hearty turkey chili hot in bowls, topped with shredded cheese, sour cream, or sliced jalapeños for extra flavor.
