How to Make Philly Cheese Steak Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a casserole dish or use an oven-safe skillet.
Step 2: Cook the Beef
Heat olive oil in a large skillet over medium-high heat.
Add the beef and cook until browned and fully cooked, breaking it apart if using ground beef.
Season with salt, pepper, and smoked paprika. Remove excess grease if necessary.
Step 3: Sauté the Vegetables
In the same skillet, add sliced onions and bell peppers.
Cook for 5–7 minutes, stirring occasionally, until softened and lightly caramelized.
Add minced garlic and cook for another 30 seconds until fragrant.
Step 4: Make It Creamy
Lower heat to medium. Add cream cheese and stir until melted and smooth.
Pour in the heavy cream and Worcestershire sauce, mixing until a rich, creamy sauce forms.
Step 5: Add the Cheese
Stir in ½ cup provolone and ½ cup mozzarella until melted and well combined.
Step 6: Bake the Casserole
Transfer the mixture to a casserole dish (if not using an oven-safe skillet).
Top with remaining provolone and mozzarella.
Bake uncovered for 20–25 minutes, or until bubbly and golden on top.
Step 7: Serve
Remove from the oven and let rest for 5 minutes.
Garnish with fresh parsley if desired and serve hot.
