Step‑by‑Step Instructions for Philly Cheesesteak Casserole
Step 1: Preheat and Prep
Begin by preheating your oven to 375°F (190°C). While the oven warms up, grease a 9x13-inch casserole dish with cooking spray or butter to ensure your Philly Cheesesteak Casserole releases easily once baked. This preparation sets the stage for a delicious meal.
Step 2: Cook the Beef
Heat a large skillet over medium heat. Add the ground beef and cook for about 6-8 minutes, stirring occasionally, until it’s browned and caramelized. Drain any excess fat to avoid a greasy casserole. This flavorful beef will serve as the hearty base for your dish.
Step 3: Sauté the Veggies
In the same skillet, incorporate the chopped green and red bell peppers, along with diced onion and minced garlic. Sauté the mixture for about 5-6 minutes until the vegetables are softened and fragrant. The colors will brighten your dish, adding both sweetness and crunch.
Step 4: Create the Creamy Base
In a mixing bowl, combine softened cream cheese, sour cream, and Dijon mustard, if using. Blend until smooth, then mix in the beaten eggs, which will bind your ingredients together. This creamy mixture is key to achieving that comfort food quality in your Philly Cheesesteak Casserole.
Step 5: Combine the Mixtures
Gently fold the sautéed beef and vegetable mixture into the creamy base you just created. If you’re using pasta, fold in the cooked pasta at this stage, ensuring everything is well combined. This blend brings the core flavors of the casserole together beautifully.
Step 6: Assemble the Casserole
Spread the combined mixture evenly into your pre-greased casserole dish. Use a spatula to ensure it’s smooth and even across the surface, creating a uniform layer that will bake into a delicious dish. This step is crucial for even cooking and flavor distribution.
Step 7: Add the Topping
Generously sprinkle your choice of shredded provolone or mozzarella cheese over the top of the casserole. The cheese forms a golden, gooey layer as it melts during baking, providing that traditional cheesesteak indulgence everyone loves in this Philly Cheesesteak Casserole.
Step 8: Bake to Perfection
Place the casserole in the preheated oven and bake uncovered for 20-25 minutes, or until the cheese is bubbly and golden brown. Keep an eye on it during the last few minutes to achieve that perfect melt that will draw everyone to the table.
Step 9: Let It Rest
Once baked, remove the casserole from the oven and let it rest for about 5 minutes before serving. This allows the layers to set, making it easier to slice into portions. Enjoying your Philly Cheesesteak Casserole warm will enhance its comforting flavors!
