Salt & pepper: Essential seasoning to enhance and balance all the flavors.

How to Make Philly Cheese Steak Casserole Recipe

Step 1: Preheat and Prepare

Start by heating your oven to 375 °F so it’s ready once your casserole mixture is combined. This ensures everything bakes evenly and the cheese melts to perfection.

Step 2: Cook the Beef and Veggies

In a large skillet, cook your ground beef or sliced steak over medium heat, stirring gently to break up the beef if using ground meat. Once the beef starts to brown, add the sliced green pepper, onion, and mushrooms. Sauté everything together until the vegetables soften and develop a slight caramelization. This step builds the foundational flavors that make the casserole sing.

Step 3: Add Cream Cheese and Worcestershire

Lower the heat and stir in the cream cheese along with the Worcestershire sauce. Continue stirring until the cream cheese melts completely and coats the beef and vegetables in a luscious, creamy mixture. This is where the casserole really begins to come together with a velvety texture.

Step 4: Assemble and Bake

Transfer your savory mixture into a baking dish and spread it out evenly. Sprinkle the generous layer of provolone or mozzarella cheese over the top to create a beautiful, melty crust as it bakes. Place the dish in the preheated oven and bake for 15 to 20 minutes until the cheese is golden, bubbly, and utterly inviting.

Garnishes

Fresh garnishes like chopped parsley or green onions can add a pop of color and a hint of freshness that contrasts nicely with the richness of the casserole. If you like a little heat, a few slices of jalapeño pepper also work wonders.

Side Dishes

This casserole pairs beautifully with a crisp green salad or roasted vegetables to complete the meal with some lightness. For those following a low-carb journey, cauliflower rice makes a perfect bed for scooping up every cheesy bite without the extra carbs.

Creative Ways to Present
