How to Make Philly Cheesesteak Casserole
Preheat Oven: Start by preheating your oven to 350 °F (175 °C) and grease an 8 8 casserole dish with a little cooking spray or butter to prevent sticking.
Saut Ingredients: In a large skillet over medium-high heat, saut the ground beef along with chopped bell peppers and onions until the beef is browned and the vegetables are tender, about 5-7 minutes. Be sure to break the beef apart as it cooks for even browning.
Season the Mixture: Drain any excess grease from the skillet and return the mixture to the heat. Season with salt, garlic powder, onion powder, and pepper to taste. Stir in Worcestershire sauce and the cream cheese, allowing it to melt beautifully into the mixture for added creaminess.
Assemble the Casserole: Spread the savory mixture evenly into the greased casserole dish, smoothing it out nicely. Layer provolone cheese slices on top, covering it generously for that melty goodness.
Bake to Perfection: Place the casserole in the preheated oven and bake for about 15 minutes, or until the cheese is bubbling and slightly golden. This will create that wonderful flavor and texture contrast that everyone loves!
Optional: Serve with a sprinkle of fresh parsley for a pop of color.
