Looking for a comforting dinner that combines the beloved flavors of a classic Philly cheesesteak in a convenient casserole format? This Philly Cheesesteak Casserole transforms the iconic sandwich into a hearty, family-friendly dish that’s perfect for busy weeknights or weekend gatherings. I’ve found that this recipe brings together all the essential elements – tender beef, melted cheese, and savory vegetables – in a format that’s both easier to serve and incredibly satisfying.
Ingredients
- 2 lbs thinly sliced beef (ribeye or sirloin)
- 2 medium green bell peppers, sliced
- 2 medium onions, thinly sliced
- 8 oz mushrooms, sliced
- 2 cups provolone cheese, shredded
- 1 cup mozzarella cheese, shredded
- 3 tablespoons butter
- 2 tablespoons olive oil
- 2 cloves garlic, minced
- 1 teaspoon Worcestershire sauce
- 1 teaspoon salt
- 1/2 teaspoon black pepper
Instructions
- Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish.
- Heat olive oil in a large skillet over medium-high heat. Add sliced beef and cook until just browned, about 5-7 minutes. Remove and set aside.
- In the same skillet, melt butter and add sliced onions, peppers, and mushrooms. Cook until vegetables are softened and onions are translucent, about 8-10 minutes.
- Add minced garlic and cook for another minute until fragrant.
- Return the beef to the skillet, add Worcestershire sauce, salt, and pepper. Stir to combine.
- Transfer the mixture to your prepared baking dish and top with both cheeses.
- Bake for 20-25 minutes, or until the cheese is melted and bubbly with golden spots.

Recipe Notes
For the best results, keep these helpful tips in mind:
- Slice your beef while it’s still slightly frozen – this makes it easier to get those signature thin slices.
- Don’t overcook the beef in the first step; it will continue cooking in the oven.
- Feel free to use different cheese combinations. While provolone is traditional, a mix of cheeses adds great depth of flavor.
- Let the casserole rest for 5-10 minutes after baking to help it set properly.
- Store leftovers in an airtight container in the refrigerator for up to 3 days.
- To reheat, cover with foil and warm in a 350°F oven until heated through, about 15-20 minutes.
This casserole reheats beautifully, making it perfect for meal prep or when you need to feed a crowd. You can also prepare the components ahead of time and assemble just before baking for a quick weeknight dinner solution.
