What is Philly Cheesesteak Casserole?

A Philly Cheesesteak Casserole is a delicious and convenient twist on the classic Philly Cheesesteak sandwich, which is a beloved icon of Philadelphia’s culinary scene. In casserole form, it typically consists of thinly sliced beef (often ribeye or sirloin), sautéed onions, and bell peppers, all layered together and baked in a dish. What sets it apart is the addition of generous amounts of melted cheese that binds the ingredients together.

The casserole version takes all the key elements of the traditional cheesesteak and transforms them into a hearty, comforting dish that’s easier to prepare and serve for a crowd. It captures the rich and savory flavors of the sandwich while allowing for variations to suit different tastes. Philly Cheesesteak Casserole recipes may incorporate additional ingredients like mushrooms or various seasonings, but the core components are beef, onions, peppers, and cheese. It’s a flavorful and satisfying way to enjoy the essence of a Philly cheesesteak in a more shareable, oven-baked form.

Ingredients needed for Philly Cheesesteak Casserole

  • Thinly Sliced Beef: High-quality, thinly sliced rib eye or sirloin steak is the star of the casserole, providing a tender and rich protein source.
  • Onions: Sautéed onions add a sweet and savory flavor, providing depth to the dish and mimicking the caramelized onions often found in a traditional Philly cheesesteak.
  • Bell Peppers: Vibrantly colored bell peppers, such as green, red, or yellow, contribute a burst of freshness and a slightly crisp texture to balance the richness of the dish.
  • Cheese: Gooey, melted cheese, often provolone or mozzarella, binds the casserole together, providing that signature cheesy goodness found in a Philly cheesesteak.
  • Butter: Butter or cooking oil is used for sautéing the onions and peppers, adding a rich, buttery flavor and helping to caramelize the onions.
  • Salt and Pepper: These seasonings enhance the flavors of the other ingredients, ensuring a well-balanced and seasoned casserole.
  • Mushrooms: Sliced and earthy, mushrooms bring a delightful umami flavor and meaty texture to the casserole.
  • Worcestershire Sauce: A savory sauce that adds a tangy and umami kick to the steak and veggies.
  • Garlic Cloves: Small but powerful, this adds a delicious flavor and smell to the casserole.
  • Cream Cheese: This tangy ingredient is what makes the sauce so creamy and delicious.
  • Heavy Cream: This makes the cream cheese a little thinner so that it can be mixed into a sauce.
  • Pepperjack Cheese: A spicy and zesty cheese that adds a kick of heat and boldness to the casserole.
  • Provolone Cheese: A mild and gooey cheese, perfect for creating a melty and cheesy topping to the dish.

How to Make Philly Cheesesteak Casserole

  • Prep: Set the oven’s temperature to 400 degrees. Next, season the sirloin steak with salt and pepper.
  • Sear the Steak: Put the oil in a big cast-iron skillet and turn the heat up to medium-high. After adding the steak, fry it for about two minutes on each side.
  • Add Sauce: Toss the meat with the Worcestershire sauce after adding it. Take out of the pan.
  • Add Veggies: After adding the Worcestershire sauce, toss the meat with it. Remove from the pan. Add the butter, garlic, bell peppers, onion, and then the mushrooms to the pan.
  • Cook: Cook for two minutes until the veggies are tender.
  • Make Sauce: Mix thoroughly after adding the heavy cream and cream cheese. After bringing everything to a simmer, cook for a further five minutes.
  • Add Meat to Veggies: Reintroduce the steak to the skillet. Add some shredded pepper jack cheese on top and mix everything together.
  • Bake: Spoon the cheesesteak mixture into a baking dish that has been lightly oiled. Arrange the slices of provolone cheese on top, and bake for 15 minutes, or until the cheese turns brown and melts.

Variations

  • Mushrooms: Sliced mushrooms sautéed with the onions and peppers can add an earthy and umami flavor to your casserole.
  • Jalapeños: For a spicy kick, add sliced jalapeños to the sautéed vegetables or sprinkle them over the top before baking.
  • Garlic: Add minced garlic to the sautéed onions and peppers for an extra layer of savory flavor.
  • Cheese Variations: While provolone and mozzarella are the classic choices, you can experiment with other cheeses like cheddar, Swiss, or even a cheese blend for different flavor profiles.
  • Low-Carb Version: If you’re following a keto or low-carb diet, skip the bread or rolls and serve the casserole on a bed of lettuce or with a side of cauliflower rice.
  • Philly Cheesesteak Stuffed Peppers: Instead of layering the ingredients in a casserole dish, you can stuff bell peppers with the cheesesteak mixture and top them with cheese. Bake until the peppers are tender.
  • Keto-Friendly Toppings: For a keto twist, consider garnishing your casserole with keto-friendly toppings like sliced avocado, diced tomatoes, or chopped scallions.
  • Hot Sauce or Sriracha: If you love a spicy kick, drizzle some hot sauce or sriracha over the casserole before serving.

Feel free to get creative with your Philly Cheesesteak Casserole by mixing and matching these variations to create a dish that suits your preferences and dietary requirements.
