01 - Preheat your oven to 400°F.
02 - In a large pot or Dutch oven, heat the olive oil over medium heat. Add the diced onion and bell pepper, then sauté until they soften, which takes approximately 5 minutes.
03 - Add the minced garlic to the pot and cook for 1 minute until it becomes fragrant.
04 - Introduce the ground turkey to the pot. Cook, breaking it apart with a spoon, until it is no longer pink, typically 5–7 minutes.
05 - Stir in the tomato paste, crushed tomatoes, diced tomatoes, kidney beans, black beans, frozen corn, chili powder, ground cumin, smoked paprika, dried oregano, and cayenne pepper (if using). Season with salt and black pepper to taste.
06 - Bring the chili mixture to a boil, then reduce the heat to a simmer. Cook uncovered for 30 minutes, stirring occasionally to prevent sticking.
07 - While the chili simmers, begin preparing the cornbread. In a large mixing bowl, whisk together the cornmeal, all-purpose flour, granulated sugar, baking powder, and salt.
08 - In a separate bowl, whisk together the milk, large eggs, and melted unsalted butter until well combined.
09 - Pour the wet ingredients into the dry ingredients. Stir just until combined; avoid overmixing.
10 - Pour the prepared cornbread batter into a greased 8-inch square baking dish. Bake for 20–25 minutes, or until the top is golden brown and a toothpick inserted into the center comes out clean.
11 - Serve the hot chili with the cornbread on the side. Garnish with fresh cilantro, sour cream, or shredded cheese as desired.
