01 - Heat a large Dutch oven or heavy pot over medium-high heat. Add ground beef and cook, breaking it apart, until browned and no longer pink, about 6 to 8 minutes. Drain excess fat if necessary.
02 - Add diced onion, red bell pepper, and jalapeño to the pot. Cook, stirring frequently, for 4 to 5 minutes until softened. Stir in minced garlic and cook for 1 minute until fragrant.
03 - Mix in chili powder, smoked paprika, cumin, oregano, cayenne, salt, and black pepper. Cook for 30 seconds to release aromas.
04 - Pour in diced tomatoes, tomato sauce, and beef broth. Scrape the bottom of the pot to deglaze and incorporate browned bits into the mixture.
05 - Bring to a simmer, reduce heat to low, and cover. Let cook for 30 minutes, stirring occasionally.
06 - Stir in drained kidney beans and simmer uncovered for 15 to 20 minutes until chili thickens to desired consistency.
07 - Taste and modify seasoning as needed. Serve hot with optional toppings such as sour cream, chopped cilantro, shredded cheddar, or sliced green onions.
