Philly Cheesesteak Casserole

Ingredients (Serves 6)

• 1½ pounds ground beef or thinly sliced steak (ribeye or sirloin)

• 1 tablespoon olive oil (if using sliced steak)

• 1 large onion, diced

• 1 green bell pepper, diced

• 1 red bell pepper, diced

• 2 cloves garlic, minced

• Salt and black pepper to taste

• 1 teaspoon Worcestershire sauce

• 4 ounces cream cheese, softened

• ½ cup sour cream

• 1 cup shredded provolone cheese (or mozzarella)

• 1 cup shredded cheddar cheese

• 4 large eggs (optional, if making it low carb and egg-based)

• Optional: cooked pasta, rice, or toasted bread to serve with

Instructions

Step 1: Preheat the oven

1. Preheat your oven to 180°C (350°F).

2. Lightly grease a 9×13 inch baking dish and set aside.

Step 2: Cook the beef

If using ground beef:

1. In a large skillet over medium heat, cook the ground beef until browned and fully cooked.

2. Drain excess fat and set aside.

If using sliced steak:

1. Heat olive oil in the skillet over medium-high heat.

2. Sear the steak slices until just cooked through, then set aside.

Step 3: Sauté vegetables

1. In the same skillet, add the diced onion and bell peppers.

2. Cook for 5 to 7 minutes, until softened.

3. Add the minced garlic and cook for 1 more minute.

4. Season with salt, pepper, and Worcestershire sauce.

Step 4: Combine filling

1. Add the cooked beef or steak back to the skillet with the vegetables.

2. Stir in cream cheese and sour cream until melted and well combined.

3. Mix in half of the shredded provolone or mozzarella cheese.

4. Adjust seasoning if needed.

Step 5: Assemble the casserole

1. Spoon the beef and cheese mixture into the prepared baking dish.

2. Sprinkle the top evenly with the remaining shredded provolone and cheddar cheese.

Optional egg-based version:

1. In a bowl, whisk 4 eggs.

2. Pour evenly over the casserole mixture for a firmer, more structured casserole.

3. Bake as directed below.

Step 6: Bake

1. Place the dish in the preheated oven.

2. Bake for 20 to 25 minutes, or until the cheese is melted and bubbly.

3. Broil for 2 to 3 minutes at the end if you want a golden top.

Step 7: Serve

1. Let the casserole cool for 5 minutes before serving.

2. Serve as-is or with toasted rolls, pasta, rice, or salad.

Tips

• For a lower-carb option, skip the bread and pasta and enjoy it as a standalone dish.

• You can substitute provolone with mozzarella or Swiss cheese depending on your taste.

• Add mushrooms for extra flavor.
