Southern Style Philly Cheesesteak Casserole

Step 4: Make the Cheese Mixture

1. In a medium bowl, combine the cream cheese, mayonnaise, Dijon mustard, garlic powder, and onion powder.
2. Stir until smooth and creamy.
3. Add 1 cup of provolone cheese and the cheddar cheese to the mixture.

Step 5: Assemble the Casserole

1. Preheat the oven to 375°F (190°C).
2. In a greased 9×13-inch baking dish, layer the base of your choice (rice, pasta, or bread cubes).
3. Spread half of the sautéed vegetables over the base.
4. Layer the cooked steak evenly over the vegetables.
5. Spread the remaining vegetables on top of the steak.
6. Pour the cheese mixture evenly over the entire dish.

Step 6: Bake to Perfection

1. Cover the casserole loosely with foil.
2. Bake in the preheated oven for 20 minutes.
3. Remove the foil and bake for an additional 10–15 minutes, or until the cheese is bubbly and slightly golden.

Step 7: Garnish and Serve

1. Remove from oven and let the casserole rest for 5–10 minutes. This helps the layers set and makes serving easier.
2. Optionally, sprinkle with chopped green onions or fresh parsley for a pop of color.
3. Serve warm with a side of pickles, coleslaw, or a light salad for a full Southern-style meal.
