• 1 cup sliced mushrooms: Enhances earthiness and soaks up flavorful juices beautifully.
• 1 tsp garlic powder: A subtle boost of aromatic flavor that ties everything together.
• 1 tsp salt: Brings out the natural savory flavors of the meat and vegetables.
• 1/2 tsp black pepper: Offers a gentle heat to balance the richness.

How to Make Cheesesteak Casserole

Step 1: Searing the Beef and Vegetables

Start by heating olive oil in a skillet over medium heat, then add the thinly sliced beef along with the green bell pepper, onion, and mushrooms. As the mixture cooks, the beef will brown beautifully while the vegetables soften, creating a rich base filled with flavor and color.

Step 2: Seasoning the Mixture

Once your beef and veggies have cooked through and developed a wonderful aroma, sprinkle garlic powder, salt, and black pepper over the skillet contents. This seasoning layer is subtle but essential, enhancing every element without overpowering.

Step 3: Assembling the Casserole

Transfer the warm beef and vegetable blend into a baking dish, spreading everything evenly. This step ensures each bite combines meat, veggies, and cheese harmoniously.

Step 4: Topping with Cheeses

Next, sprinkle the shredded provolone over the top, followed by the grated Parmesan. The provolone melts smoothly, while the Parmesan adds an irresistible golden crust once baked.

Step 5: Baking to Perfection

Pop the dish into a preheated oven at 375°F and bake for about 15 minutes. You’ll know it’s ready when the cheeses have melted fully and formed a bubbly, tantalizing crust that invites you to dive in.

Garnishes

Fresh garnishes can brighten this rich casserole beautifully. Consider sprinkling chopped fresh parsley or green onions over the top for a pop of color and a touch of fresh flavor that complements the hearty layers inside.

Side Dishes

This Cheesesteak Casserole pairs wonderfully with crisp green salads, roasted vegetables, or even a simple side of garlic bread. The freshness and crunch of these sides balance the creamy, savory nature of the casserole perfectly.

Creative Ways to Present

While this dish is a crowd-pleaser straight from the baking dish, try scooping portions into individual ramekins for a charming presentation. You can also serve it alongside soft hoagie rolls or atop toasted bread slices to give a nod to the classic cheesesteak sandwich experience.

Make Ahead and Storage

Storing Leftovers

Leftover Cheesesteak Casserole keeps well in the refrigerator for up to 3 days. Store it in an airtight container to maintain freshness and prevent the beef from drying out. When you’re ready to eat, the flavors become even more concentrated and delicious.

Freezing

This casserole freezes beautifully, making it an excellent meal prep option. Let it cool completely, then wrap tightly with plastic wrap and aluminum foil or place it in a freezer-safe container. It will stay good for up to 2 months without losing its texture or flavor.

Reheating

For the best results, reheat your frozen or refrigerated Cheesesteak Casserole in the oven at 350°F until warmed through and the cheese is bubbly again. If you’re in a hurry, the microwave works fine too, but the oven will help maintain that freshly baked taste and texture.

FAQs

Can I use other types of cheese besides provolone and Parmesan?

Absolutely! While provolone and Parmesan create a classic flavor profile, feel free to experiment with mozzarella for extra meltiness or cheddar for a sharper taste. Just be sure to choose cheeses that melt well to keep the casserole gooey and delicious.

Is it possible to make this dish vegetarian?

Yes! Simply omit the beef and substitute with hearty veggies like extra mushrooms, zucchini, or eggplant. To keep the savory flavor, consider adding plant-based meat alternatives or a splash of soy sauce for umami depth.

How thin should the beef slices be?

Thinly sliced beef is key here to ensure quick, even cooking and tender bites. If you can’t find pre-sliced steak, you can partially freeze a beef strip and slice it thinly with a sharp knife at home.

Can I prepare the Cheesesteak Casserole ahead of time and bake it later?

Definitely! Assemble the casserole, cover it tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking straight from chilled.

What can I serve with this casserole for an easy weeknight dinner?

A simple tossed green salad and crusty bread work perfectly to round out your meal without adding too much prep time. The fresh salad helps balance the richness of the casserole.
