How to Make Philly Cheesesteak Casserole

The process of creating this casserole is straightforward and allows for some flexibility with the ingredients. At its core, the recipe comprises ground beef, a rainbow of vegetables, and, of course, decadent cheeses, all baked to perfection. Let’s dive into what you’ll need to bring this comfort food to life.

Ingredients

Here’s what you’ll need to gather to create this delectable dish:

1 ½ lbs ground beef (or shaved steak)
1 medium onion (diced)
1 green bell pepper (diced)
1 red bell pepper (diced)
8 oz mushrooms (sliced)
2 cloves garlic (minced)
1 teaspoon salt
½ teaspoon black pepper
½ teaspoon smoked paprika (optional)
1 tablespoon Worcestershire sauce
8 oz cream cheese (softened)
½ cup mayonnaise
2 large eggs
1 cup shredded provolone cheese
1 cup shredded mozzarella cheese

Feel free to substitute the vegetables based on what you have on hand. For example, jalapeños can add a spicy kick, while zucchini or spinach can incorporate more greens into the meal.

Directions

Step 1: Preheat and Prepare

Preheat your oven to 375°F (190°C). Lightly grease a 9×13 baking dish to prevent sticking.

Step 2: Cook the Beef

In a large skillet over medium-high heat, brown the ground beef until it’s no longer pink. Be sure to drain any excess grease to keep the casserole from becoming greasy.

Step 3: Add Vegetables

Stir the diced onion, green and red bell peppers, sliced mushrooms, and minced garlic into the skillet. Sauté the mixture until the vegetables are softened, roughly about 5–6 minutes. Season with salt, black pepper, smoked paprika, and Worcestershire sauce. Once cooked, remove from heat and evenly spread the mixture into the prepared baking dish.

Step 4: Make the Creamy Mixture

In a separate bowl, whisk together the softened cream cheese, mayonnaise, and eggs until the mixture is smooth and well-combined.

Step 5: Assemble the Casserole

Spread the creamy mixture over the layer of beef and vegetables. Generously sprinkle the provolone and mozzarella cheeses on top.

Step 6: Bake

Place the dish in the oven and bake for 25–30 minutes, until the top is bubbly and golden.

Step 7: Serve

Allow the casserole to rest for 5 minutes before serving. This dish pairs wonderfully with a side salad, crusty bread, or even toasted hoagie rolls for a true cheesesteak experience.

How to Store

Leftovers? No problem! Store any uneaten casserole in an airtight container in the refrigerator for up to 3 days. If you’d like to keep it for longer, freezing is a great option. Just make sure to wrap the casserole tightly with foil or place it in a freezer-safe container. It can be frozen for up to three months. When ready to enjoy again, thaw overnight in the refrigerator before reheating in the oven at 350°F (175°C) until warmed through.

Tips to Make

For an extra layer of flavor, consider incorporating sautéed onions and peppers before layering them in the casserole. Adding a teaspoon of Italian seasoning can also elevate the flavor profiles. If you’re in a rush, pre-cooked chicken or rotisserie chicken can be a quick substitute for beef.

Variations

There are endless ways to make this recipe your own! Try adding jalapeños for heat or swap out the provolone for cheddar cheese for a sharper taste. If you’re looking for a vegetarian option, consider replacing the beef with lentils or black beans, maintaining the same seasonings for that classic flavor.
