Philly Cheesesteak Casserole Recipe | Cheesy & Savory Comfort

I have to admit, the first time I made this Philly Cheesesteak Casserole Recipe, I was craving all the flavors of a classic Philly cheesesteak but didn’t want the hassle of a sandwich. As I layered tender beef, sautéed peppers, onions, and gooey cheese into a casserole dish, the kitchen quickly filled with an irresistible aroma.

By the time it came out of the oven, golden and bubbling, I couldn’t wait to dig in. Each bite delivered all the flavors of a traditional sandwich in a fork-friendly, comforting meal. Now, this has become my go-to dish for busy weeknights or casual get-togethers. For a delicious side, you can also enjoy Garlic Butter Herb Steak Bites With Potatoes Recipe alongside it.

Ingredients

1 lb ground beef – I use 85/15 for a nice balance of flavor and juiciness. Thinly sliced ribeye works if you want a more authentic Philly taste.
1 medium yellow or sweet onion, sliced – Adds a mild, caramelized sweetness.
1 green bell pepper, sliced – Green peppers give that classic Philly crunch; red or yellow can add extra sweetness.
2 cloves garlic, minced – Fresh garlic enhances the savory flavor.
4 oz cream cheese – Adds a creamy texture and helps bind the beef mixture.
1/4 cup beef broth – Keeps the casserole moist and flavorful.
Salt and pepper – Essential for seasoning the beef and vegetables
1/2 tsp paprika or steak seasoning – Adds depth and a subtle smoky flavor.
6 oz provolone cheese, sliced – Melts perfectly for the cheesy topping. Mozzarella or a mix of cheeses works too.

Note: Serves 4–6 generously. You can pair this with a hearty side like Farmhouse Beans And Sausage Recipe for a complete meal.

How to Make Philly Cheesesteak Casserole Recipe?

Preheat the Oven

Start by setting your oven to 375°F (190°C). Lightly grease your 9×13-inch baking dish to prevent sticking and ensure easy cleanup.

Cook the Beef

In a large skillet over medium heat, brown the ground beef until no pink remains. Drain any excess grease to avoid a greasy casserole.

Sauté Vegetables

Add onions and bell peppers to the skillet. Cook for about 5–7 minutes until softened and lightly caramelized. Stir in minced garlic for the last minute of cooking.

Add Creaminess

Reduce heat to low and stir in the cream cheese until melted. Pour in beef broth for moisture and season with salt, pepper, and paprika or steak seasoning.

Layer in Baking Dish

Spread the beef and vegetable mixture evenly in the prepared dish. Lay provolone cheese slices on top, overlapping slightly for complete coverage.

Bake

Place in the oven and bake for 15–18 minutes until the cheese is melted and bubbly. For a golden top, broil an additional 1–2 minutes.

Serve

Allow the casserole to rest for 5 minutes before serving. It’s delicious on its own, or over toasted hoagie rolls, pasta, or rice.

Additional Tips for Making this Recipe Better

I like to flash-cook ribeye or sirloin if I’m using steak for a more authentic flavor.
Letting the casserole rest a few minutes before serving makes slicing and serving easier.
Adding a splash of beef broth while reheating keeps it moist.
For extra flavor, I sometimes sprinkle a bit of shredded provolone on top before broiling.

How to Serve Philly Cheesesteak Casserole Recipe?

I love serving this casserole straight from the oven with a garnish of fresh parsley for color. You can plate it over toasted rolls to mimic a classic sandwich or serve alongside a crisp green salad. A few extra caramelized onions on top make it look restaurant-worthy.
