01 - Heat a large pot or Dutch oven over medium heat. Add the sliced sausage and cook for 5–6 minutes, stirring occasionally, until browned. Remove from the pot and set aside.
02 - In the same pot, add the diced onion and red bell pepper. Sauté for 4–5 minutes until softened.
03 - Incorporate the minced garlic and finely chopped jalapeño (if using) into the pot. Cook for 1 minute until fragrant.
04 - Stir in the tomato paste, chili powder, ground cumin, smoked paprika, dried oregano, cayenne pepper (if using), salt, and black pepper. Cook for 1 minute, stirring constantly, to toast and release their aromas.
05 - Add the crushed tomatoes, broth, drained and rinsed kidney beans, drained and rinsed black beans, and the browned sausage to the pot. Stir thoroughly to combine all components.
06 - Bring the mixture to a gentle boil, then reduce the heat to low. Allow the chili to simmer uncovered for 25–30 minutes, stirring periodically, until it has thickened and the flavors have melded.
07 - Taste the chili and adjust the salt and pepper as needed to achieve your desired flavor profile.
08 - Ladle the hot chili into bowls. Serve immediately, optionally garnished with chopped fresh cilantro, shredded cheddar cheese, sour cream, and sliced green onions.
