What is Philly Cheesesteak Casserole?

Philly Cheesesteak Casserole is a delicious deconstructed version of the iconic Philadelphia sandwich. Instead of being served in a hoagie roll, the steak, sautéed veggies, and melted cheese are baked together in a casserole dish. It’s a low-carb version of the traditional cheesesteak, but it’s packed with the same flavors—thinly sliced beef, onions, bell peppers, mushrooms, and provolone cheese. This casserole is great for family dinners or gatherings when you want the bold taste of a cheesesteak in a hearty, comforting format.

Substitutions and Variations

This casserole is highly adaptable, so feel free to adjust the ingredients based on your preferences or dietary needs:

1. Meat: Ribeye steak is classic, but you can use any tender steak like sirloin or flank steak. Ground beef can also be used for a quicker option.
2. Cheese: Provolone cheese is a must for a traditional cheesesteak flavor, but you can mix in or substitute with mozzarella, cheddar, or even American cheese for a creamier version.
3. Vegetables: While bell peppers, onions, and mushrooms are traditional, feel free to add extra veggies like zucchini, spinach, or jalapeños for added texture or spice.
4. Low-Carb Option: This recipe is naturally low-carb, but for an extra low-carb or keto-friendly version, you can skip the mushrooms or add more cream cheese for extra richness.
5. Sauce: You can swap the Worcestershire sauce for a splash of soy sauce or steak sauce for a slightly different flavor profile.

Step-by-Step Cooking Instructions

Here’s how to make this delicious and easy Philly Cheesesteak Casserole from start to finish:

Step 1: Preheat the Oven

1. Preheat your oven to 375°F (190°C).

Step 2: Sauté the Vegetables

1. Heat Olive Oil: In a large skillet, heat 1 tablespoon of olive oil over medium heat.
2. Sauté the Veggies: Add the sliced onions and green bell peppers to the skillet. Sauté for 5-7 minutes, or until softened.
3. Add the Mushrooms and Garlic: Stir in the sliced mushrooms and minced garlic. Cook for an additional 4-5 minutes until the mushrooms have released their moisture and the garlic is fragrant. Remove the veggies from the skillet and set them aside.

Step 3: Cook the Steak

1. Heat More Oil: In the same skillet, add the remaining 1 tablespoon of olive oil over medium-high heat.
2. Sear the Steak: Add the thinly sliced steak, season with salt, pepper, and Worcestershire sauce, and cook for 3-5 minutes until browned. The steak doesn’t need to be fully cooked as it will finish in the oven.
3. Remove from Heat: Set the cooked steak aside.

Step 4: Prepare the Cheese Mixture

1. Mix the Cheese Ingredients: In a medium bowl, combine the softened cream cheese, 1 ½ cups of shredded provolone, 1 cup of shredded mozzarella, and the lightly beaten eggs. Mix until smooth and creamy. Season with salt and pepper to taste.

Step 5: Assemble the Casserole

1. Grease a Baking Dish: Lightly grease a 9x13-inch baking dish with cooking spray or olive oil.
2. Layer the Ingredients: Spread half of the sautéed vegetables across the bottom of the dish. Add a layer of the cooked steak over the veggies. Spread the remaining sautéed vegetables on top of the steak.
3. Add the Cheese Mixture: Pour the cream cheese mixture evenly over the steak and vegetables, spreading it out with a spatula if necessary.
4. Top with Cheese: Sprinkle the remaining shredded provolone (½ cup) over the top of the casserole.

Step 6: Bake the Casserole

1. Bake: Bake the casserole in the preheated oven for 25-30 minutes, or until the top is golden brown and the cheese is melted and bubbly.

Step 7: Rest and Serve

1. Let It Rest: Allow the casserole to rest for 5-10 minutes before serving. This will help the cheese set and make it easier to slice.
2. Garnish: Garnish with chopped fresh parsley for a touch of color and freshness.

Common Mistakes to Avoid

1. Overcooking the Steak: Be careful not to overcook the steak when you sear it. It will continue to cook in the oven, so just give it a quick sear.
2. Skipping the Veggie Sauté: Make sure to sauté the onions, peppers, and mushrooms before adding them to the casserole. This helps develop their flavor and prevents them from releasing too much water during baking.
3. Not Letting It Rest: Allowing the casserole to rest after baking is important to let the layers set, making it easier to slice and serve.
4. Overloading with Cheese: While more cheese might sound great, adding too much can make the casserole overly greasy or soggy. Stick to the recommended amounts for a perfect texture.
