Ingredients
Scale
Bell Peppers
- 1 large green bell pepper, sliced and seeded
- 1 large yellow bell pepper, sliced and seeded
- 1 large red bell pepper, sliced and seeded
Vegetable Mix
- 2 tablespoons salted butter
- 1 small onion, thinly sliced
- 3 cloves garlic, minced
- 8 ounces cremini mushrooms, thinly sliced
Meat and Cheese
- 1 1/2 pounds deli-style roast beef, thinly sliced
- 6 slices provolone cheese
- 1 cup shredded mozzarella cheese
Instructions
- Prepare Peppers: Slice the green, yellow, and red bell peppers, removing all seeds and ribs to ensure a tender texture in the casserole.
- Sauté Vegetables: In a large skillet, melt the salted butter over medium heat. Add the thinly sliced onion and minced garlic, sautéing until fragrant and translucent. Stir in the thinly sliced cremini mushrooms and prepared bell peppers, cooking until all vegetables are tender and slightly caramelized.
- Add Beef: Mix the thinly sliced deli-style roast beef with the sautéed vegetables. Season lightly with salt and pepper if desired, stirring to combine evenly.
- Assemble Casserole: Transfer the beef and vegetable mixture to a baking dish. Layer the provolone slices over the top, then sprinkle the shredded mozzarella cheese evenly.
- Bake: Preheat your oven to 350°F (175°C). Bake the casserole uncovered for 15 minutes to heat through and melt the cheese.
- Broil: Switch the oven to broil and cook for 3-5 minutes more until the cheese is browned and bubbly. Keep a close eye to prevent burning.
- Serve: Remove from the oven and allow to cool slightly before serving to enjoy a warm, cheesy Philly Cheesesteak casserole.
Notes
- You can substitute the roast beef with thinly sliced ribeye steak for a more authentic Philly cheesesteak flavor.
- Use a mix of provolone and mozzarella for a deliciously creamy and melty cheese topping.
- For extra spice, add a pinch of red pepper flakes when sautéing the vegetables.
- This casserole pairs well with a simple side salad or crispy fries.
- Leftovers can be stored covered in the fridge for up to 3 days and reheated in the oven.
