Ingredients Breakdown

Here’s everything you’ll need to make this cheesy, savory Philly cheesesteak casserole. Serves 6.

Main Ingredients:

• 2 lbs ground beef (80/20 fat ratio preferred)
• 1 large onion, diced
• 2 large bell peppers (green, red, or mixed), diced
• 2 cloves garlic, minced

Cheesy Layers:

• 8 oz cream cheese, softened to room temperature
• 2 tbsp Worcestershire sauce
• 8 oz provolone cheese, sliced
• 1.5 cups mozzarella cheese, shredded

Seasonings & Fat:

• 1 tbsp olive oil
• Salt and pepper, to taste

Tools & Equipment Needed

• 9×13-inch baking dish
• Large skillet
• Oven
• Spatula or wooden spoon
• Knife and cutting board
• Measuring cups and spoons
• Cheese grater (if not using pre-shredded mozzarella)

Step-by-Step Instructions

1. Preheat Oven and Prepare Baking Dish

Set your oven to 350°F (175°C). Spray a 9×13 baking dish with non-stick cooking spray. This will prevent sticking and make clean-up a breeze.

2. Sauté Vegetables

Heat 1 tbsp olive oil in a large skillet over medium heat. Add diced onions and bell peppers, cooking for 5–6 minutes until softened and fragrant. Stir occasionally to prevent burning. Add minced garlic and cook for an additional 30 seconds, stirring constantly.

3. Cook Ground Beef

Add the ground beef to the skillet, breaking it apart with a spatula. Season generously with salt and pepper. Cook for 7–8 minutes until the beef is fully browned with no pink remaining. Drain excess fat if needed to avoid a greasy casserole.

4. Add Flavor and Creaminess

Stir in 2 tbsp Worcestershire sauce, ensuring it coats the beef and vegetables evenly. Reduce the heat to low and add 8 oz softened cream cheese. Stir until fully melted and incorporated, creating a creamy, flavorful base for your casserole.

5. Assemble the Casserole

Transfer the beef and vegetable mixture to your prepared baking dish, spreading it evenly. Layer torn pieces of provolone cheese over the top, followed by 1.5 cups of shredded mozzarella for that perfect, gooey cheese pull.

6. Bake to Perfection

Place the casserole in the preheated oven and bake for 22–25 minutes, or until the cheese is melted, bubbly, and lightly golden on top.

7. Rest and Serve

Allow the casserole to rest for 5 minutes before serving. This helps the flavors meld and makes it easier to slice. Serve hot, straight from the dish.

Tips & Variations

• Cheese Options: Swap provolone for cheddar or Monterey Jack if desired.
• Spice Level: Add a pinch of crushed red pepper flakes or cayenne to the beef mixture for a subtle kick.
• Vegetarian Option: Substitute beef with a plant-based ground meat alternative and use dairy-free cheeses.
• Make it Low-Fat: Use 90/10 ground beef and reduced-fat cheeses to lighten the dish without sacrificing flavor.
• Extra Veggies: Mushrooms, zucchini, or spinach can be added for additional nutrients and volume.

Flavor Profile & Pairings

This casserole delivers a rich, cheesy, and savory flavor with the classic umami of a Philly cheesesteak.

The texture is hearty with a mix of tender beef, soft vegetables, and melty, slightly golden cheese on top.

Side Dish Suggestions
