Easy One-Pan Philly Cheesesteak Casserole Tips, FAQ & printable recipe

Tips for success

To achieve a more authentic flavor, consider adding a dash of Worcestershire sauce or a pinch of garlic powder to the beef while it browns.

These small additions can elevate the savory notes of the meat and complement the sweetness of the peppers and mushrooms beautifully.

If a crispier top is desired, place the casserole under the broiler for one to two minutes after the cheese has melted. Keep a very close eye on it during this time, as the cheese can go from perfectly melted to burnt in seconds under direct high heat.

Variations

• Spicy Cheesesteak: Add diced jalapeños or a dash of hot sauce to the beef mixture while cooking. This provides a pleasant kick that pairs well with the richness of the melted cheese.
• Onion Lover's Version: Incorporate one cup of thinly sliced yellow onions during the sautéing phase. The natural sweetness of the onions complements the peppers and enhances the overall flavor profile of the dish.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

Freeze for up to 2 months in a freezer-safe container.

Reheat

Reheat in the oven at 350 degrees Fahrenheit until warmed through.

Allow any leftovers to cool to room temperature for no more than two hours. Once cooled, transfer the remaining casserole into an airtight container.

Keep it stored in the refrigerator, where it will maintain its quality for up to three days. Ensure the container is sealed tightly to prevent the absorption of other odors.

The beef and vegetable mixture can be prepared up to one day in advance and stored in the refrigerator.

When ready to serve, transfer the mixture to the casserole dish, top with the cheese, and bake according to the instructions. Add a few extra minutes to the baking time to account for starting with cold ingredients.

Serving ideas

Serve the casserole directly from the glass dish to keep it warm. It pairs wonderfully with a side of steamed green beans or a crisp garden salad to balance the richness of the cheese and beef. The casserole is hearty enough to serve as a complete meal on its own.

For individual portions, use a large spoon to scoop the casserole onto plates, ensuring each serving includes a generous portion of the cheesy topping.

The leftovers are just as delicious the next day, making this an excellent option for meal planning throughout the busy work week.

Easy One-Pan Philly Cheesesteak Casserole

Prep 15 minCook 30 minRest 5 minTotal 50 minServes 6

Ingredients

• 2 lb ground beef
• 2 cups bell peppers, sliced
• 1 cup mushrooms, sliced
• 2 cups shredded cheese

Instructions

1. Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a spatula, until browned and no longer pink. Drain excess fat if necessary. Add the sliced bell peppers and mushrooms to the skillet and sauté until they are tender and the moisture has evaporated.
2. Transfer the cooked ground beef and vegetable mixture into a 9x13 inch glass casserole dish. Spread the mixture into an even layer using your metal spatula to ensure uniform cooking and cheese distribution. This creates the perfect base for the cheese topping.
3. Top the casserole evenly with the shredded cheese. Place the dish into a preheated oven at 375 degrees Fahrenheit. Bake until the cheese is completely melted and bubbling across the entire surface. Remove from the oven and allow the dish to rest for five minutes before serving to let the cheese set.
