01 - Heat the vegetable oil in a large pot or Dutch oven over medium heat. Add the ground beef and cook, breaking it up with a spoon, until browned and no longer pink, about 6-8 minutes. Drain excess fat if necessary.
02 - Add the diced onion, red and green bell peppers, and jalapeño to the pot. Sauté until vegetables are softened, about 5 minutes.
03 - Stir in the minced garlic and cook for 1 minute until fragrant.
04 - Add the chili powder, cumin, smoked paprika, cayenne, oregano, salt, and black pepper. Stir well to coat the meat and vegetables with the spices.
05 - Mix in the tomato paste and cook for 2 minutes, stirring frequently.
06 - Add the crushed tomatoes, kidney beans, and beef broth. Stir until well combined.
07 - Bring the chili to a simmer. Reduce the heat to low, cover, and simmer for 45 minutes, stirring occasionally.
08 - Taste and adjust seasonings as needed. For a thicker chili, simmer uncovered for an additional 10-15 minutes.
09 - Serve hot, garnished with your choice of toppings such as chopped cilantro, sour cream, or shredded cheese.
