Ingredients

Instructions

  1. Step 1: In a large skillet over medium-high heat, cook 1.5 lb ground beef with 1 medium finely chopped yellow onion, 1 medium diced green bell pepper, and 3 minced garlic cloves until the beef is browned and the vegetables are soft, about 7-8 minutes. Drain excess fat.
  2. Step 2: Stir in 15 oz tomato sauce, 1/2 cup ketchup, 1 tbsp Worcestershire sauce, 2 tbsp brown sugar, 1 tbsp yellow mustard, 1 tsp salt, and 1/2 tsp black pepper. Bring to a simmer and cook for 5 minutes to blend flavors.
  3. Step 3: Transfer the beef mixture to a slow cooker set to low. Spread evenly, then sprinkle 2 cups shredded sharp cheddar cheese over the top.
  4. Step 4: In a small bowl, combine 1 cup Italian seasoned bread crumbs with 2 tbsp melted butter. Sprinkle the breadcrumb mixture evenly over the cheese layer.
  5. Step 5: Cover and cook on low for 2-3 hours until the cheese is melted and the topping is golden and crisp. Serve warm with bread or over toasted buns.
