Brown the Beef: Heat the olive oil over medium-high heat in a large pot or Dutch oven. Add the chuck beef and brown on all sides. Do not crowd the pan; you may need to do this in batches. Once browned, remove the beef and set it aside.
500 g Chuck beef, 2 tbsp Olive oil
Sauté Vegetables: In the same pot, add the chopped onions and cook until they are translucent. Add the garlic, bell peppers, jalapeño (if using), and sauté until they soften.
1 Onion, chopped, 2 Bell peppers, 1 Jalapeño, chopped, 3 cloves Garlic, minced
Combine Ingredients: Return the browned beef to the pot. Add the diced tomatoes, kidney beans, black beans, chili powder, cumin, smoked paprika, and beef broth. Stir to combine.
2 cans Diced tomatoes
Add Worcestershire Sauce: Stir in the Worcestershire sauce, salt, and pepper to taste.
1 tbsp Worcestershire sauce, Salt & Pepper
Simmer: Bring the mixture to a boil, then reduce the heat to low. Cover and let it simmer for at least 2 hours, stirring occasionally. The longer it simmers, the more the flavors will meld together.
Adjust Seasoning: Before serving, taste your chili and adjust the seasoning if necessary. For an extra punch of flavor, you might want to add another splash of Worcestershire sauce.
1 tbsp Worcestershire sauce
Serve: Serve your chili hot, garnished with your favorite toppings such as shredded cheese, sour cream, chopped green onions, or fresh cilantro.
