How to best store your Philly Cheese Steak Casserole

Store any leftover casserole in an airtight container. This will prevent it from drying out and keep the flavors locked in.

Store the casserole in the refrigerator for 4 to 5 days.

Reheating the casserole in the oven is the best option for this dish. Preheat your oven to around 350°F (175°C). Cover the casserole dish with aluminum foil to stop the top from browning or drying out too quickly. Reheat for about 15-20 minutes.

You can use the microwave to reheat the casserole if you're short on time. Keep in mind that the texture might not be as crisp as when reheated in the oven.

Reheating on the stovetop is a good option to prevent the casserole from becoming soggy. Add a little water or broth to the bottom of the pan to create steam and prevent sticking.

Avoid overheating the casserole, as it can lead to it drying out and losing flavor.

It's worth noting that this Philly Cheesesteak Casserole doesn't freeze well. Freezing can alter the texture of the cheese and vegetables upon thawing and reheating.

Variations to this Cheese Steak Casserole

Here are some tasty ways to switch this base recipe:

• Instead of sirloin, use other cuts of tender beef like ribeye steak or flank steak. Ribeye is extra rich and even more marbled. Flank steak is a little leaner.
• Swap out sliced steak for lean ground beef. Brown the ground beef before layering it into the casserole.
• Add sautéed mushrooms to the vegetable mix.
• Bring some heat by mixing in sliced jalapeños or red chili flakes.
• Mix and match cheeses like cheddar, mozzarella, Swiss, or blue cheese.
• Embrace the true Philly experience by adding chopped pickled hot peppers, or cherry peppers to your casserole.
• Serve your casserole with a side of salsa and slices of creamy avocado. The fresh flavors complement the rich casserole beautifully.
