  • ½ tsp black pepper
  • ½ tsp cayenne pepper optional
  • 1 tbsp Worcestershire sauce
  • 1 tbsp olive oil

Method
 

  1. Heat olive oil in a skillet over medium heat.
  2. Brown the ground beef until fully cooked, then drain excess grease if needed.
  3. Add diced onion and garlic, cooking until fragrant.
  4. Transfer the beef mixture to the slow cooker.
  5. Add tomatoes, tomato paste, beef broth, Worcestershire sauce, and all seasonings.
  6. Stir everything together until well combined.

Notes

For deeper flavor, let the chili rest for 15–20 minutes after cooking before serving. The flavors become richer as the chili sits, making it even better for next-day meal prep.
