1 tbsp olive oil

Instructions

Preheat the Oven: Preheat your oven to 375°F (190°C) to prepare for baking the casserole.
Sauté Vegetables: Heat the olive oil in a large skillet over medium heat. Add the diced onion and bell peppers and cook until softened, then remove them from the skillet and set aside.
Cook Ground Beef: In the same skillet, add the ground beef and cook until it’s nicely browned. Drain any excess fat to avoid greasiness.

Assemble the Casserole: Transfer the beef and vegetable mixture into a baking dish. Arrange the provolone cheese slices evenly over the top, followed by sprinkling the shredded mozzarella cheese across the surface.
Bake: Place the baking dish in the preheated oven and bake for 15–20 minutes, or until the cheese is melted and bubbly with slightly golden spots.
Rest and Serve: Allow the casserole to rest for 5 minutes after removing from the oven to set and cool slightly before serving.

Notes

Use ground beef with at least 20% fat content (80/20) for the best flavor and moisture.
Feel free to swap provolone with another melting cheese like cheddar or fontina for a different twist.
For added spice, consider adding crushed red pepper flakes to the beef mixture.
This casserole can be reheated the next day and tastes great as leftovers.
Make sure to fully soften the cream cheese before adding to ensure smooth incorporation.
