Ingredients You’ll Need

The magic of the Ultimate Philly Cheesesteak Casserole Recipe lies in its simplicity. Each ingredient plays a key role in building layers of flavor and texture that bring this dish to life. From the rich ground beef that forms the hearty base to the creamy eggs that add lusciousness, every component is essential.

1½ lb ground beef: The foundation of the casserole, providing rich, savory depth and meaty texture.
2 bell peppers, chopped: These bring a bright crunch and subtle sweetness that balance the richness.
½ onion, chopped: Adds a natural sweetness and enhances the overall savoriness when sautéed.
2 tsp minced garlic: A punch of garlic elevates the flavor with just the right amount of aromatic bite.
1 tsp seasoned salt: Essential for seasoning, it infuses the mixture with a harmony of herbs and spices.
8 slices provolone cheese: Melts perfectly on top, lending a creamy, mild tang that ties everything together.
4 large eggs: The binding agent that sets the casserole firm while keeping it tender.
¼ cup heavy whipping cream: Adds moisture and a silky texture to the egg mixture.
2 tsp Worcestershire sauce: Boosts umami and complexity for that authentic Philly cheesesteak flavor.

How to Make Ultimate Philly Cheesesteak Casserole Recipe

Step 1: Prep Your Oven and Baking Dish

Start by preheating your oven to 350°F (175°C). While it’s warming up, lightly grease a 9×13-inch baking dish to ensure your casserole won’t stick. This simple prep step will make your cleanup a breeze later on and help that golden crust form beautifully during baking.

Step 2: Brown the Ground Beef

Grab a large skillet and heat it over medium-high. Add the ground beef, stirring and breaking it apart as it cooks. You want to brown it until there’s no pink left — this process locks in flavor and gives your casserole a meaty backbone that’s utterly satisfying.

Step 3: Sauté the Vegetables

Once the beef is ready, toss in the chopped bell peppers, onions, minced garlic, and sprinkle in the seasoned salt. Cook these together for 4 to 5 minutes until the vegetables soften and the garlic becomes fragrant. This combination creates the iconic Philly cheesesteak flavor profile with vibrant color and inviting aroma.

Step 4: Transfer to Baking Dish

Spread the beef and vegetable mixture evenly across the prepared baking dish. Distributing everything uniformly ensures each bite will have a perfect balance of meat and veggies.

Step 5: Whisk Together the Egg Mixture

In a medium bowl, whisk the eggs, heavy whipping cream, and Worcestershire sauce until smooth. This creamy custard will set during baking to hold the casserole together while adding richness and moisture.

Step 6: Pour and Top

Pour the egg mixture over the meat and vegetables in the baking dish. Then, layer the 8 slices of provolone cheese neatly on top. The cheese will melt into a luscious, golden layer that is both beautiful and delicious.

Step 7: Bake Until Perfect

Place the casserole in the oven and bake for 25 to 30 minutes. You’ll know it’s done when the eggs are set firmly and the cheese has melted into a bubbly, lightly browned masterpiece ready to be devoured.

How to Serve Ultimate Philly Cheesesteak Casserole Recipe

Garnishes

To elevate your Ultimate Philly Cheesesteak Casserole Recipe presentation, consider garnishing with freshly chopped parsley or a sprinkle of crushed red pepper flakes for a little kick. These add visual appeal and a fresh burst of flavor that brightens each mouthful.

Side Dishes

This casserole pairs wonderfully with a crisp green salad dressed in tangy vinaigrette or some roasted garlic mashed potatoes to soak up every bit of cheesy, beefy goodness. For a lighter option, steamed green beans or sautéed asparagus complement the rich flavors beautifully.

Creative Ways to Present

If you want to impress guests, serve this casserole in individual ramekins for a personal touch. Alternatively, scoop portions onto toasted hoagie rolls to recreate the traditional Philly cheesesteak vibe in casserole form. Adding pickled jalapeños on the side can add a fantastic zesty crunch that wakes up the senses.

Make Ahead and Storage

Storing Leftovers

After enjoying your Ultimate Philly Cheesesteak Casserole Recipe, store any leftovers in an airtight container in the refrigerator. It will keep well for up to 3 days, making for delicious next-day meals or easy reheats throughout the week.

Freezing

This casserole freezes beautifully. To freeze, let it cool completely, then wrap it tightly with plastic wrap and aluminum foil or place it in a freezer-safe container. It can be frozen for up to 2 months without losing its scrumptious flavors and texture.

Reheating

Reheat leftover casserole either in a microwave or oven. For the oven, preheat to 350°F and cover with foil to prevent over-browning, warming for about 15-20 minutes until heated through. Microwaving is quicker; just cover with a microwave-safe lid and heat in short bursts to avoid drying out.

FAQs

Can I use other types of cheese for the casserole?

Absolutely! While provolone is traditional, you can substitute with mozzarella, cheddar, or even pepper jack for a spicy twist. Each cheese lends a different character, so feel free to experiment based on your taste preferences.

Is it possible to make this recipe vegetarian?

Yes! Replace the ground beef with a plant-based meat alternative or diced mushrooms for a hearty texture. Use vegetable broth instead of Worcestershire sauce to keep it meat-free, and the rest of the ingredients remain the same.

Can I prepare this recipe ahead of time?

Definitely. Assemble the casserole up to the baking step, then cover and refrigerate for up to 24 hours before baking. This makes it great for busy days or entertaining when you want to do as much prep as possible ahead.

What sides go best with Ultimate Philly Cheesesteak Casserole Recipe?

Side dishes like simple salads, roasted veggies, or crispy fries complement the casserole’s flavors and texture. They help balance the richness and make the meal feel complete without overshadowing the main dish.

How can I make the casserole spicier?

To add a spicy kick, incorporate diced jalapeños or a pinch of cayenne pepper into the meat and vegetable mixture. You can also top with hot sauce or sprinkle crushed red pepper flakes just before serving for customizable heat.
