• 1 medium onion, diced
• 1 green bell pepper, diced
• 1 red bell pepper, diced
• 2 cloves garlic, minced
• 1 tsp Worcestershire sauce
• Salt and black pepper, to taste

For the creamy base:

• 8 oz cream cheese, softened
• 1/2 cup mayonnaise or sour cream

• 1 tsp onion powder
• 1 tsp garlic powder

For the topping:

• 1 1/2 cups shredded provolone or mozzarella cheese
• 1 cup shredded cheddar cheese

Instructions

1. Preheat the oven: Set your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.
2. Cook the beef: In a large skillet over medium heat, brown the ground beef until no pink remains. Drain excess grease.
3. Add vegetables: Add diced onions, bell peppers, and minced garlic. Sauté until the vegetables are soft and fragrant, about 5–7 minutes. Stir in Worcestershire sauce, salt, and pepper.
4. Prepare the creamy mixture: In a medium bowl, combine cream cheese, mayonnaise (or sour cream), milk, onion powder, and garlic powder. Mix until smooth and creamy.
5. Combine and layer: Add the beef mixture into the prepared baking dish. Spread the creamy mixture evenly over the top, then sprinkle with both cheeses.
6. Bake: Place the casserole in the preheated oven and bake for 20–25 minutes, or until the cheese is melted, bubbly, and lightly golden around the edges.
