Philly Cheese Steak Casserole Recipe

This recipe uses simple ingredients and delivers maximum flavor.

Prep Time: 20 minutes
Cook Time: 35 minutes
Total Time: 55 minutes
Serves: 6-8

Ingredients

For the Casserole Base:

· 1 ½ lbs ribeye steak, thinly sliced (or shaved sirloin)*
· 1 large onion, thinly sliced
· 1 large green bell pepper, thinly sliced
· 1 large red bell pepper, thinly sliced
· 8 oz mushrooms, sliced (optional)
· 2 cloves garlic, minced
· 2 tablespoons olive oil
· 1 tablespoon Worcestershire sauce
· 1 teaspoon Italian seasoning
· Salt and black pepper to taste

For the Egg & Bread Layer:

· 6 large eggs
· ½ cup milk
· 1 (16 oz) tube refrigerated biscuit dough (like Pillsbury Grands), cut into quarters OR 4 cups cubed French or Italian bread

For the Cheese Topping:

· 2 cups shredded provolone cheese
· 1 cup shredded mozzarella cheese

Instructions

  1. Preheat Oven: Preheat your oven to 375°F (190°C). Grease a 9×13 inch baking dish.
  2. Cook the Steak & Veggies: In a large skillet, heat the olive oil over medium-high heat. Add the sliced steak and cook until just browned. Remove the steak with a slotted spoon and set aside.
  3. Sauté Vegetables: In the same skillet, add the onions, bell peppers, and mushrooms (if using). Sauté for 6-8 minutes until they are softened and starting to caramelize. Add the minced garlic and cook for one more minute.
  4. Combine Filling: Return the steak to the skillet. Add the Worcestershire sauce, Italian seasoning, salt, and pepper. Stir everything together and cook for another minute. Remove from heat.
  5. Prepare the Egg Mixture: In a medium bowl, whisk together the eggs and milk until well combined. Season with a pinch of salt and pepper.
  6. Assemble the Casserole:
    · Layer 1: Spread the steak and vegetable mixture evenly in the bottom of the prepared baking dish.
    · Layer 2: If using cubed bread, scatter it evenly over the steak mixture. If using biscuit dough, scatter the quartered biscuit pieces over the top.
    · Layer 3: Pour the egg and milk mixture evenly over everything, making sure it soaks into the bread or biscuit layer.
    · Layer 4: Sprinkle the shredded provolone and mozzarella cheeses evenly over the top.
  7. Bake: Bake for 25-35 minutes, or until the top is golden brown, the cheese is bubbly, and the center is set (the eggs should be fully cooked).
  8. Rest and Serve: Let the casserole stand for 5-10 minutes before slicing and serving. This allows the layers to set.

Tips for Success & Variations

· Getting Thinly Sliced Steak: The easiest method is to buy pre-shaved steak from the grocery store (often labeled “shaved steak” or “cheesesteak meat”). If slicing your own, partially freeze the steak for 30-60 minutes; it will be much easier to slice paper-thin.
· Bread vs. Biscuits: Cubed bread gives a more savory, strata-like texture. Biscuit dough creates a fluffy, dumpling-like top layer. Both are excellent!
· Cheese Choices: Provolone is classic, but you can use all mozzarella, a Swiss/Gruyère blend, or even a sprinkle of Cheez Whiz on top after baking for ultimate authenticity.
· Add Flavor: A splash of soy sauce or a tablespoon of steak seasoning in the steak and veggie mix can deepen the flavor.
· Make it a Pasta Bake: For a different twist, substitute 2 cups of uncooked penne or rotini pasta for the bread/biscuits. Cook the pasta until just al dente before assembling. You may need to increase the egg/milk mixture to 1 cup of milk to help it cook through.
· Make Ahead: You can assemble the casserole completely, cover it, and refrigerate it overnight. Bake it straight from the fridge, adding 5-10 minutes to the baking time.

Why This Casserole is a Winner

· All the Flavor, None of the Fuss: You get the iconic Philly Cheesesteak taste without standing over the griddle to assemble individual sandwiches.
· Comfort Food at its Best: It’s hearty, cheesy, and incredibly satisfying.
· Great for Leftovers: It reheats beautifully for easy lunches throughout the week.

Enjoy this delicious and easy take on a classic sandwich
