Common Mistakes to Avoid
When making your Philly cheesesteak casserole, it’s easy to overlook some key details that can affect the final dish.
- Bold seasoning: Failing to season your steak properly can lead to a bland casserole. Always add salt and pepper while cooking the meat for better flavor.
- Bold overcooking vegetables: Cooking the peppers and onions too long can make them mushy. Sauté them just until they soften for a nice texture.
- Bold using cold ingredients: Adding cold cream cheese or half-and-half directly from the fridge can cause clumping. Allow these ingredients to come to room temperature before mixing.
- Bold skimping on cheese: Cheese is essential for that gooey, melty texture. Use enough cheddar and mozzarella for optimal cheesiness!
- Bold neglecting baking time: Underbaking your casserole can result in a watery dish while overbaking can dry it out. Keep an eye on it until the cheese is bubbling and golden.
