Instructions

Preheat Oven: Preheat your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to prepare it for the casserole mixture.
Sauté Vegetables: Heat 1 tablespoon of olive oil in a large skillet over medium heat. Add the sliced onion and both green and red bell peppers, cooking for 5 to 6 minutes until they are softened but still vibrant.
Add Garlic: Stir in the minced garlic and cook for about 30 seconds until it becomes fragrant. Remove the cooked vegetables from the skillet and set them aside.
Cook Beef: In the same skillet, add the thinly sliced beef sirloin along with 1/2 teaspoon salt and 1/2 teaspoon black pepper. Cook the beef for 4 to 5 minutes until it is browned and cooked through.
Combine Ingredients: Return the sautéed vegetables to the skillet with the beef. Stir in 4 ounces of softened cream cheese and 1/2 cup beef broth, blending everything until the mixture is creamy and well combined.
Prepare for Baking: Transfer the beef and vegetable mixture evenly into the prepared baking dish, spreading it out into a flat layer.
Add Cheese Layers: Layer 6 slices of provolone cheese evenly over the top of the mixture, then sprinkle 1 cup of shredded mozzarella cheese on top to create a cheesy crust.
Bake: Place the baking dish in the preheated oven and bake for 15 to 18 minutes, or until the cheeses are melted, bubbly, and slightly golden on the edges.
Rest and Serve: Remove the casserole from the oven and let it rest for 5 minutes to set before serving. This helps the flavors meld and makes serving easier.

Notes

For extra heat, consider adding sliced jalapeños or a pinch of red pepper flakes while sautéing the vegetables.
You can substitute beef sirloin with thinly sliced ribeye or flank steak for a different texture and flavor.
Use full-fat cream cheese for the creamiest texture, but reduced-fat versions can be used to lower calories.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days and reheated before serving.
Serve alongside a fresh green salad or crusty bread for a complete meal.
