What Makes This Version of Philly Cheesesteak Casserole Stand Out?

“This casserole elevates the classic dish to new heights with its rich flavors and easy preparation.”

Flavor Punch

Unlike traditional Philly cheesesteaks, this casserole allows all the flavors to meld together beautifully, creating a rich and creamy experience. The addition of cream cheese provides a smooth texture, while Worcestershire sauce adds a depth of flavor that elevates the dish.

Texture Balance

The combination of sautéed onions and bell peppers not only adds a pop of color but also gives the casserole a satisfying crunch that contrasts perfectly with the gooey cheese. The blend of provolone and mozzarella offers a delightful stretch, making every bite a cheesy dream.

Simple Ingredients

If you’re looking for a leaner option, you can substitute with ground turkey or chicken to keep the dish lighter without sacrificing flavor. Each of these substitutions will alter the nutritional profile, but they will still taste delicious.

How Do You Make this Scrumptious Casserole Step-by-Step?

“Making this casserole is straightforward, and the results are impressive!”

Step 1

Preheat your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick spray for easy cleanup.

Step 2

Heat olive oil on medium heat in a large skillet. Add diced onions and bell peppers, cooking for about 5-6 minutes until softened and fragrant. The colors will brighten up, making it visually appealing.

Step 3

Add minced garlic, stirring for an additional 30 seconds to prevent burning and intensify its flavor.

Step 4

Introduce the ground beef to the skillet, breaking it apart as it cooks. Season with salt and pepper to taste. Cook for 7-8 minutes or until it’s nicely browned without any pink spots.

Step 5

If there’s excess fat, drain it off. Stir in Worcestershire sauce for that umami kick, then lower the heat and mix in the softened cream cheese until melted and creamy. The mixture will become a luscious filling.

Step 6

Transfer this mix into your prepared baking dish and spread it evenly. Tear provolone cheese and layer it over the beef mixture, finishing off with a generous sprinkle of shredded mozzarella cheese.

Step 7

Bake in the preheated oven for 22-25 minutes. You’ll know it’s done once the cheese is melted, bubbly, and lightly golden. Allow it to rest for 5 minutes before serving, letting the flavors meld beautifully.

FAQ

What ingredients are in a Philly cheesesteak?

A classic Philly cheesesteak is made with thinly sliced ribeye steak, sautéed onions, and melted cheese, often provolone, Cheez Whiz, or American cheese. Some versions also include bell peppers or mushrooms, though purists stick to the basics. All ingredients are layered inside a soft hoagie roll.

What is Philly cheesesteak casserole?

A Philly cheesesteak casserole is a baked dish inspired by the traditional sandwich but prepared in a one-pan format. It typically includes seasoned beef, onions, peppers, and melted cheese combined with pasta, potatoes, or a creamy base. The result is a hearty, low-effort meal that captures the flavor of the original sandwich.

How to make a steak casserole?

To make a steak casserole, start by browning sliced or cubed beef with onions, garlic, and your choice of vegetables. Combine it with a sauce or creamy mixture, add starch like pasta or potatoes, top with cheese or breadcrumbs, and bake until bubbly and golden. It’s an easy, flexible recipe that adapts to whatever ingredients you have on hand.

What is the secret ingredient in Philly cheesesteak?

Many say the “secret” ingredient is the ultra-thinly sliced ribeye, which cooks quickly and absorbs flavor. Others insist the magic comes from the cheese, especially Cheez Whiz, for its creamy, melty texture. The combination of tender beef, caramelized onions, and perfectly melted cheese is what truly defines the iconic taste.

What kind of sauce goes with Philly cheesesteak?

Philly cheesesteaks traditionally skip heavy sauces and rely on melted cheese for creaminess. However, popular additions include garlic aioli, horseradish mayo, chipotle sauce, or a simple cheese sauce made from provolone or Cheez Whiz. These sauces enhance the sandwich without overpowering the beef and onions.
