Ingredients You’ll Need

Here’s what you’ll need to build this crave-worthy casserole. Everything is easy to find and likely already in your kitchen.

• Ground beef: Quick-cooking and full of flavor; it’s the hearty base of the casserole. You can also use shaved steak for a more traditional texture.
• Bell peppers: Go with green, red, or a mix for sweet and savory notes. They bring freshness and color.
• Onion: Sautéed until golden, onions add a touch of sweetness and depth to balance the savory beef.
• Garlic: Adds that unmistakable aromatic punch. Don’t skip it!
• Cream cheese: Helps create a rich, creamy texture that binds the filling together.
• Worcestershire sauce: Just a splash elevates the beef with a subtle umami kick.
• Salt and pepper: Essential for seasoning every layer perfectly.
• Provolone cheese: Melts beautifully with a mild, smoky flavor. You can also use mozzarella or Swiss for variety.
• Eggs: Beaten into the mixture to help it set like a true casserole.

Variations

• Use Thinly Sliced Ribeye: Want to get closer to the authentic Philly cheesesteak? Go for ribeye or shaved beef instead of ground beef.
• Add Mushrooms: A handful of sautéed mushrooms adds earthiness and makes the dish even heartier.
• Cheese Swap: Try white American, mozzarella, or cheddar if provolone isn’t your favorite.
• Spice It Up: Add chopped jalapeños or a pinch of crushed red pepper for a little heat.
• Make it a Breakfast Casserole: Toss in some hash browns or roasted potatoes and serve with eggs for a weekend brunch version.

How to Make Easy Philly Cheese Steak Casserole

Step 1: Preheat and Prep

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish or any casserole dish you have on hand.

Step 2: Sauté the Vegetables

In a large skillet over medium heat, sauté sliced onions and bell peppers in a bit of oil until softened and slightly caramelized. Remove and set aside.

Step 3: Brown the Beef

In the same skillet, cook the ground beef until browned, breaking it up with a spoon. Drain any excess fat. Stir in minced garlic, Worcestershire sauce, salt, and pepper. Mix well.

Step 4: Mix in the Cream Cheese

With the heat still on low, add cream cheese to the beef and stir until fully melted and creamy. Then mix in the sautéed vegetables.

Step 5: Assemble the Casserole

Spread the beef and veggie mixture evenly into the prepared baking dish. Top with slices or shredded provolone cheese.

Step 6: Add the Egg Mixture

Whisk the eggs in a small bowl and pour them evenly over the casserole. This helps the casserole firm up and stay sliceable.

Step 7: Bake

Bake uncovered for 20–25 minutes, or until the cheese is bubbly and lightly golden and the center is set.

Step 8: Cool and Serve

Let it cool for 5 minutes to set, then slice and serve hot.

Pro Tips for Making the Recipe

• Don’t Overcook the Peppers: You want them soft but not mushy—just enough to bring out their sweetness while keeping a bit of bite.
• Use Room Temperature Cream Cheese: It blends more easily with the hot beef, creating a smoother filling.
• Eggs Are the Binder: Don’t skip them. They help the casserole stay firm enough to cut into neat portions.
• Let It Rest: Allow it to sit for a few minutes after baking to let everything settle and firm up.

How to Serve

This casserole is hearty enough to be a meal on its own, but here are a few ideas to round it out:

On Its Own

Serve it straight from the oven with a side of pickles or a green salad for a complete, no-fuss meal.

Sandwich Style

Scoop some into a soft hoagie roll and toast it under the broiler for an open-faced Philly melt. Absolute heaven.

Side Pairings

Pair with roasted broccoli, coleslaw, or crispy sweet potato fries for balance and texture.

Make Ahead and Storage

Storing Leftovers

Store cooled leftovers in an airtight container in the fridge for up to 4 days.

Freezing

Yes, you can freeze it! Let it cool completely, then freeze in portions. Wrap tightly in foil and place in a freezer-safe bag or container. Good for up to 3 months.

Reheating

Reheat in the microwave or in the oven at 350°F until hot and bubbly. If frozen, thaw overnight in the fridge first.
