Philly Cheesesteak Casserole

 


👩‍🍳 How to Make Philly Cheesesteak Casserole

1. Preheat the Oven

Preheat to 375°F (190°C). Lightly grease a 9x13-inch baking dish.

2. Cook the Beef

Heat olive oil in a skillet over medium-high heat. Add sliced beef and cook until browned. Season with salt and pepper. Remove and set aside.

3. Sauté the Veggies

In the same skillet, sauté onions, peppers, and mushrooms until soft and lightly caramelized (about 5–7 minutes).

4. Mix the Cheeses

In a bowl, mix cream cheese and mayonnaise. Stir in Parmesan, half the provolone, and half the mozzarella until smooth.

5. Combine Seasonings

In a small bowl, stir together garlic powder, onion powder, oregano, basil, red pepper flakes, salt, and pepper.

6. Assemble

  • Layer half of the beef in the dish.

  • Sprinkle with half the seasoning.

  • Add the veggie mixture.

  • Spread the creamy cheese blend evenly.

  • Top with remaining beef and seasoning.

  • Sprinkle the rest of the shredded cheeses on top.

7. Bake

Bake uncovered for 25–30 minutes, or until golden and bubbly.

8. Rest & Serve

Let sit 5–10 minutes before slicing. Serve hot and enjoy the melty magic!

🥗 What to Serve with It

  • A crisp green salad with balsamic vinaigrette

  • Roasted broccoli or Brussels sprouts

  • Cauliflower rice, mashed potatoes, or even spooned into hoagie rolls for sliders!

🧠 Tips for Success

  • Use pre-sliced deli roast beef if you're in a rush.

  • Let it rest before cutting so the layers hold together.

  • Want it extra creamy? Add a bit of sour cream to the cheese mixture!

  • Fridge: Store leftovers in an airtight container for up to 4 days.
