In a large skillet over medium heat, add the ground beef and chorizo sausage. Cook until browned, breaking it apart with a spatula, about 5-7 minutes. Drain excess fat.

Sauté Vegetables

In the same skillet, add the chopped onion, bell pepper, garlic, and jalapeño (if using). Sauté until the vegetables are softened, about 5 minutes.

Cooking

Combine Ingredients in Crockpot

Transfer the browned meat and sautéed vegetables to a large crockpot. Add diced tomatoes, tomato paste, kidney beans, black beans, chili powder, cumin, smoked paprika, salt, black pepper, red pepper flakes, beef broth, and Worcestershire sauce.

Mix Well

Stir all ingredients together until well combined. Make sure the spices and liquids are evenly distributed.

Cook on Low

Cover the crockpot and cook on low for 6-8 hours, or high for 3-4 hours, until the chili is thick and the flavors meld together.

Serving

Serve the Chili

Once cooked, stir the chili and serve hot. Top with your favorite toppings such as shredded cheese, sour cream, or chopped green onions, if desired.
