Step 4: Bake
- Cover the casserole with foil and bake for 20 minutes.
- Remove the foil and bake for an additional 10–15 minutes, until the cheese is bubbly and slightly browned.
- Let the casserole rest for 5–10 minutes before serving—this helps it set and makes it easier to cut.
Step 5: Serve and Enjoy
Garnish with freshly chopped parsley and serve hot. This casserole pairs wonderfully with a simple side salad, garlic bread, or even roasted potatoes.
Tips for the Perfect Philly Cheesesteak Casserole
- Cheese matters: Use a combination of provolone and mozzarella for the classic Philly flavor and gooey texture.
- Vegetables first: Sautéing peppers and onions enhances their sweetness and brings out the best in the casserole.
- Customize your beef: You can use leftover steak, roast beef, or even thinly sliced chicken if you prefer.
- Make-ahead option: Assemble the casserole a day in advance and refrigerate. Bake just before serving for convenience.
