Ingredients for Cheesy Low Carb Philly Cheesesteak Casserole

1 ½ pounds ground beef (or shaved steak, if preferred)
1 tablespoon olive oil (if using shaved steak)
1 green bell pepper, thinly sliced
1 red bell pepper, thinly sliced
1 medium onion, thinly sliced
2 cloves garlic, minced
1 teaspoon salt
½ teaspoon black pepper
1 teaspoon Worcestershire sauce
4 ounces cream cheese, softened
1 ½ cups shredded provolone cheese (or mozzarella as an alternative)
Optional: chopped parsley for garnish

Step-by-Step Guide: How to Make Philly Cheesesteak Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish and set aside.

Step 2: Cook the Beef

In a large skillet over medium heat, cook the ground beef until browned and cooked through, breaking it up as it cooks. Drain any excess fat.

If using shaved steak, heat olive oil in the skillet first, then cook the steak slices quickly until browned. Remove from skillet and set aside.

Step 3: Sauté Vegetables

In the same skillet, add sliced peppers and onions. Sauté for about 5–7 minutes, until they’re softened but still a bit crisp. Add garlic, salt, pepper, and Worcestershire sauce, and cook for another minute.

Step 4: Combine and Assemble

Turn off the heat and add the cooked beef back to the skillet with the vegetables. Stir in the cream cheese until melted and combined. Transfer the mixture to the prepared baking dish and spread evenly.

Sprinkle the shredded provolone cheese over the top.

Step 5: Bake

Bake for about 20 minutes, or until the cheese is melted and bubbly. Let it cool slightly before serving.

Step 6: Garnish and Serve

Sprinkle with fresh parsley if desired, and serve hot.
