Step-by-Step Guide to Making Philly Cheese Steak Casserole

1. Preheat the Oven

Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

2. Cook the Beef and Vegetables

Heat a large skillet over medium heat and add the ground beef. Cook until browned, breaking it up with a spatula.
Add the diced bell peppers, onions, and garlic, stirring occasionally. Cook for about 5 minutes until softened.
Sprinkle in the seasoned salt and Worcestershire sauce. Stir well and remove from heat.

3. Prepare the Egg Mixture

In a medium bowl, whisk together the eggs, heavy cream, and hot sauce (if using).
This mixture will help hold the casserole together while keeping it moist and creamy.

4. Assemble the Casserole

Spread the beef and vegetable mixture evenly into the prepared baking dish.
Pour the egg mixture over the top, ensuring it distributes evenly.
Lay the provolone cheese slices over the top, covering as much as possible.

5. Bake to Perfection

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the eggs are set and the cheese is bubbly and golden brown.

6. Serve and Enjoy

Let the casserole cool for a few minutes before slicing.
Serve hot and enjoy the melty, cheesy, beefy goodness!

Make it cheesier by adding shredded mozzarella or extra provolone.
Let it rest for 5 minutes before slicing to help it hold its shape.
