1. Can I prepare this casserole ahead of time?
Yes, you can assemble the casserole up to 24 hours in advance. Cover it tightly and refrigerate until you’re ready to bake. When baking from cold, you may need to add a few extra minutes to the cooking time to ensure it’s heated through.

2. What type of cheese works best for this casserole?
While provolone is traditional for Philly cheesesteaks, you can experiment with other melting cheeses like mozzarella, cheddar, Swiss, gouda, or Monterey Jack to suit your taste preferences.

3. Can I substitute the ground beef with another protein?
Absolutely! Thinly sliced ribeye steak is a classic choice, but you can also use ground chicken, turkey, or even plant-based meat substitutes for a different twist.

4. How should I store leftovers, and what’s the best way to reheat them?
Store any leftover casserole in an airtight container in the refrigerator for up to 5 days. To reheat, use the microwave or warm it in the oven until heated through.

5. Can I add other vegetables to the casserole?
Certainly! Adding vegetables like mushrooms or spinach can enhance the flavor and nutritional profile of the dish. Sauté them along with the onions and peppers before mixing them into the casserole.
