Heat olive oil in a large pot over medium heat. Add the diced onion and sauté until translucent and fragrant, about 3-4 minutes.
Add the minced garlic and cook for another minute until it becomes aromatic.
Increase the heat and add the ground turkey, breaking it apart with a spoon, cooking until browned and cooked through, about 5-6 minutes.
Stir in chili powder, smoked paprika, cumin, cayenne pepper, and the secret smoky ingredient, mixing well to coat the meat and vegetables evenly.
Add the diced tomatoes with their juice, stirring to combine everything and scraping up any browned bits from the bottom of the pot.
Bring the mixture to a gentle simmer, then add the drained black beans and corn kernels. Stir to incorporate all ingredients evenly.
Reduce the heat to low and let the chili simmer uncovered for 10-15 minutes, allowing the flavors to meld and the chili to thicken slightly.
Taste and season with salt and pepper as needed to balance the smoky and spicy flavors.
Once thickened and flavorful, ladle the hot chili into bowls and serve immediately, topped with your favorite garnishes if desired.
