Optional Browning Step: Heat olive oil in a pan over medium heat. Brown the minced beef until no longer pink, then transfer to the slow cooker.
Combine Ingredients: Add chopped onion, garlic, canned tomatoes, tomato paste, Worcestershire sauce, smoked paprika, oregano, salt, and pepper to the slow cooker. Stir well.
Slow Cook: Pour in the beef stock, cover, and cook on low for 6-8 hours or on high for 3-4 hours. Stir occasionally if possible.
Final Touches: Taste and adjust seasoning if needed. Serve with pasta, rice, or tortillas depending on the dish variation.
Enjoy! Garnish with fresh herbs, cheese, or a squeeze of lime for extra flavor
