Step-by-Step Instructions

1. Prepare the Oven & Dish

Preheat oven to 350°F (175°C).

Spray a 9×13 baking dish with non-stick spray and set aside.

2. Sauté the Vegetables

Heat olive oil in a large skillet over medium heat.

Add diced onions and bell peppers. Cook for 5-6 minutes until softened and fragrant.

Add minced garlic and cook for another 30 seconds, stirring constantly to prevent burning.

The aroma at this stage is warm and inviting the foundation of the dish.

3. Brown the Beef

Add ground beef to the skillet.

Break it apart with a spatula and season generously with salt and pepper.

Cook for 7-8 minutes until fully browned with no pink remaining.

Drain excess fat if necessary.

4. Add Flavor & Creaminess

Stir in Worcestershire sauce, coating the meat mixture evenly.

Reduce heat to low and add softened cream cheese.

Stir continuously until the cream cheese melts completely into a creamy, cohesive mixture.

It should look rich and velvety not dry.

5. Assemble the Casserole

Transfer the beef mixture into the prepared baking dish.

Spread evenly.

Layer torn provolone slices across the top.

Sprinkle shredded mozzarella evenly over everything.

6. Bake to Perfection

Bake for 22-25 minutes, until cheese is melted, bubbly, and lightly golden.

Remove from oven and let rest for 5 minutes before serving. This allows the casserole to set and flavors to meld.
