Heat a heavy-bottomed pot over medium heat until warm, then add a splash of oil. Add chopped onions and minced garlic, cooking until the onions turn translucent and fragrant, about 5-7 minutes, with a gentle sizzle filling the air.
Increase the heat to medium-high and crumble in the ground turkey. Use your spoon to break it apart, cooking until it browns evenly and develops a slight crust, about 8 minutes, filling the kitchen with a savory aroma.
Add chopped bell peppers and a teaspoon of smoked paprika, stirring to combine. Cook for about 5 minutes, until the peppers soften slightly and the mixture turns vibrant.
Pour in the canned diced tomatoes along with their juice, then add a splash of chicken broth. Stir everything together, bringing the mixture to a gentle simmer with bubbling sounds.
Sprinkle in ground cinnamon, chili powder, and cayenne pepper, stirring well to evenly distribute the spices. The mixture will emit a warm, spicy fragrance as the flavors meld.
Reduce the heat to low and let the chili simmer uncovered for 25-30 minutes, stirring occasionally. The chili will thicken slightly, and the aroma will deepen, creating a cozy, inviting scent.
Taste the chili and adjust seasoning with salt, pepper, or additional spices if needed. The flavors should be rich, smoky, and well-balanced, with a hint of sweetness from the cinnamon.
Serve hot in bowls, garnished with fresh cilantro or a squeeze of lime for bright contrast. Enjoy the hearty, spicy hug of this cozy turkey chili.
