- 1 medium onion, diced
- 3 cloves garlic, minced
- 4 oz cream cheese
- 1/2 cup heavy cream
- 1 teaspoon Worcestershire sauce
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon Italian seasoning
- 1 1/2 cups shredded provolone or mozzarella cheese
- 1/2 cup shredded cheddar cheese
Kitchen Equipment Needed

- 9×13 inch baking dish
- Oven
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a baking dish with cooking spray or butter to prevent sticking.
Step 2: Cook the Beef
Heat olive oil in a large skillet over medium heat. Add the ground beef and cook until browned. Break it apart with a spoon while cooking so the meat becomes evenly crumbled.
Once fully cooked, drain excess grease if necessary.
Step 3: Sauté the Vegetables
Add chopped onions and bell peppers to the skillet. Cook for about 5 minutes until they become soft and slightly caramelized. Stir in the minced garlic and cook for another minute.
Step 4: Add the Creamy Base
Lower the heat and add cream cheese, heavy cream, Worcestershire sauce, salt, pepper, and Italian seasoning. Stir until the cream cheese melts and everything becomes creamy and well combined.
Step 5: Transfer to Baking Dish
Pour the mixture into your prepared casserole dish and spread it evenly.
Step 6: Add Cheese Topping
Sprinkle provolone (or mozzarella) and cheddar cheese over the top.
Step 7: Bake the Casserole
Place the casserole in the oven and bake for 15–20 minutes, until the cheese melts and becomes golden and bubbly.
Step 8: Rest and Serve
Let the casserole rest for about 5 minutes before serving. This allows the flavors to settle and makes it easier to slice.

- Let the peppers slightly caramelize to bring out their natural sweetness.
