01 - Heat a large Dutch oven or heavy-bottomed pot over medium-high heat. Add ground beef and cook, breaking it up, 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 occasionally, until vegetables soften, about 4 to 5 minutes. Stir in minced garlic and cook for 1 minute.
03 - Incorporate chili powder, smoked paprika, cumin, oregano, cayenne pepper, salt, and black pepper. Cook while stirring for 30 seconds until fragrant.
04 - Pour in diced tomatoes, tomato sauce, and beef broth. Scrape the bottom of the pot to deglaze and combine all ingredients.
05 - Bring mixture to a simmer. Reduce heat to low, cover, and cook for 30 minutes, stirring occasionally.
06 - Stir in kidney beans and simmer uncovered for another 15 to 20 minutes until the chili thickens to desired consistency.
07 - Taste the chili and add more salt or spices if needed. Serve hot with optional toppings such as sour cream, chopped cilantro, shredded cheddar cheese, or sliced green onions.
