Gather all your ingredients and tools. Preheat your oven to 180°C (350°F).
Chop the onion, bell peppers, and mince the garlic, aiming for rustic, uneven cuts that add charm to the dish.
Heat oil in a large skillet over medium-high heat. Add the diced onions and minced garlic, sautéing until they turn golden and fragrant, about 5 minutes. The kitchen will fill with a warm aroma.
Add the chopped bell peppers to the skillet and cook until they soften and start to char slightly, about 7 minutes, enhancing smoky flavor and adding color.
Transfer the sautéed vegetables to a large pot. In the same skillet, add the ground beef and cook over medium-high heat until browned and caramelized, about 10 minutes, stirring frequently. The meat should be golden and no longer pink.
Pour the browned meat into the pot with vegetables. Stir in chili powder, smoked paprika, and cook for 2 minutes until the spices are toasted and fragrant.
Add the diced tomatoes and kidney beans to the pot. Stir well, then bring to a gentle simmer over medium heat.
Let the chili simmer uncovered for at least 30 minutes, stirring occasionally. The mixture should thicken and the flavors meld, filling your kitchen with a smoky aroma.
Check the chili’s thickness: it should be rich and coating the back of a spoon. If too thick, add a splash of water; if too thin, simmer longer until it reaches your desired consistency.
Taste the chili and adjust salt or spice levels. Let it rest off the heat for 10 minutes to allow flavors to settle before serving.
Serve the Halloween chili hot, garnished with your favorite toppings. Enjoy the hearty, smoky flavors with a festive, comforting touch!
