Ingredients

2 lbs ground beef (80/20 fat ratio preferred)

1 large onion, diced (yellow recommended)

2 large bell peppers, diced (green, red, or mixed)

2 cloves garlic, minced (fresh)

8 oz cream cheese, softened to room temperature (full-fat preferred)

2 tbsp Worcestershire sauce

Salt and pepper to taste

8 oz provolone cheese, sliced (torn into smaller pieces)

1½ cups mozzarella cheese, shredded

1 tbsp olive oil for cooking

Instructions

Step 1: Preheat your oven to 350°F (175°C) and spray a 9×13 baking dish with non-stick spray. Heat olive oil in a large skillet over medium heat.

Step 2: Add diced onions and bell peppers to the hot oil, cooking for 5-6 minutes until softened and fragrant. Stir in minced garlic and cook for another 30 seconds, stirring constantly.

Step 3: Add ground beef to the skillet, breaking it up with a spatula. Season generously with salt and pepper. Cook for 7-8 minutes until browned with no pink remaining. Drain excess fat if needed.

Step 4: Stir in Worcestershire sauce, then reduce heat to low. Add softened cream cheese and mix until melted and creamy.

Step 5: Transfer the beef mixture to the prepared baking dish and spread evenly. Layer torn provolone pieces over the top, then sprinkle with shredded mozzarella cheese.

Step 6: Bake for 22-25 minutes until the cheese is melted, bubbly, and lightly golden. Let rest for 5 minutes before serving.

Tips & Variations

Use 80/20 ground beef for the best balance of flavor and moisture without being too greasy.

Try adding sliced mushrooms or jalapeños for extra flavor and texture.

Swap provolone for cheddar or pepper jack for a different cheese profile.

Serve with low-carb sides like cauliflower rice or roasted vegetables to keep the meal balanced.

Storage

Store leftover casserole in an airtight container in the refrigerator for up to 4 days. For longer storage, wrap individual portions tightly and freeze for up to 3 months. Reheat in the oven at 325°F until warmed through or microwave covered with a damp paper towel to prevent drying out. Adding a sprinkle of fresh cheese when reheating can refresh the dish.
