How to Make Philly Cheesesteak Casserole

This recipe is simple to assemble and delivers a comforting, cheesy, and satisfying meal.

Preheat Oven and Brown the Beef

First, preheat your oven to 350°F (177°C). While the oven heats, place the ground beef into a large sauté pan over medium-high heat. Use a spatula to break up the beef and season it with 2 teaspoons of sea salt and ½ teaspoon of black pepper. Cook the beef for about 8-10 minutes, stirring occasionally, until it is browned and cooked through.

Sauté the Vegetables

Once the beef is cooked, add the sliced bell peppers and onion directly into the pan. Season the vegetables with ½ tablespoon of Italian seasoning, 1 teaspoon of smoked paprika, and ½ teaspoon of garlic powder. Continue to sauté the mixture for 10-15 minutes, stirring occasionally, until the vegetables are tender and slightly softened.

Add Creamy Sauce and Bake

After the vegetables have softened, add the pieces of softened cream cheese and the ¼ cup of chicken broth to the pan. Stir everything together until the cream cheese is fully melted and the sauce is smooth and creamy. Transfer this entire beef and vegetable mixture to a large baking dish.

Arrange the slices of provolone cheese on top, overlapping them slightly to cover the entire surface of the casserole. Bake the Philly cheesesteak casserole for 10-15 minutes, until the cheese is completely melted and has turned a lovely golden brown.
