01 - Heat a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the ground beef and cook until browned, breaking it apart with a wooden spoon. Drain excess fat if necessary.
02 - Add the diced onion, red and green bell peppers, jalapeños, and garlic to the pot. Sauté for 5 to 6 minutes until the vegetables are softened and fragrant.
03 - Stir in the chili powder, cumin, smoked paprika, cayenne pepper, oregano, salt, black pepper, and sugar. Cook for 1 minute until the spices become fragrant.
04 - Add the tomato paste, diced tomatoes with their juices, and beef broth. Stir thoroughly to combine all ingredients and dissolve the tomato paste.
05 - Bring the mixture to a simmer, then reduce heat to low. Cover the pot and cook for 45 minutes, stirring occasionally to prevent sticking.
06 - Stir in the drained kidney beans. Simmer uncovered for 20 to 30 minutes longer, allowing the chili to thicken to your desired consistency.
07 - Taste the chili and adjust salt, pepper, or heat level as needed. Serve hot with your choice of garnishes such as cilantro, sour cream, cheddar cheese, or green onions.
