Hearty Bubble Up Philly Cheese Steak Casserole Tips, FAQ & printable recipe

Tips for success

For a more robust flavor, add a teaspoon of garlic powder or onion powder to the ground beef as it browns. If you enjoy a bit of heat, sprinkle a pinch of crushed red pepper flakes over the beef mixture before topping it with the biscuits. Adjusting the seasoning during the initial cooking phase allows the flavors to permeate the entire casserole, resulting in a more complex and satisfying final dish.

To achieve an extra-crispy topping, you can lightly brush the tops of the biscuits with a small amount of melted butter or olive oil before placing them in the oven.

This helps the dough brown more evenly and adds a beautiful sheen to the finished casserole. If you prefer a softer texture, simply ensure the cheese layer is thick enough to protect the biscuits from direct, intense heat during the baking process.

Variations

• Spicy Philly Casserole: Add chopped jalapeños to the beef mixture and use a pepper jack cheese instead of mozzarella for a spicy kick that complements the savory beef.
• Mushroom and Onion Casserole: Sauté sliced cremini mushrooms and yellow onions with the beef to create a deeper, more earthy flavor profile that mimics the classic steak sandwich.

Storage and make-ahead

Fridge

Store in an airtight container for up to 3 days.

Freezer

Freeze in a freezer-safe container for up to 1 month.

Reheat

Reheat in a 350°F oven until hot, or microwave individual portions until steaming.

If you have leftovers, allow the casserole to cool completely at room temperature for no more than 2 hours. Once cooled, transfer the portions into an airtight container. Keep the container in the refrigerator to maintain freshness.

The casserole can be stored this way for up to 3 days. When ready to eat, ensure it is heated thoroughly until the center is steaming hot before serving it to your guests or family members.

You can prepare the beef and pepper mixture up to 24 hours in advance and store it in the refrigerator. When you are ready to bake, simply spread the cold mixture into the baking dish, top with the fresh biscuit pieces and cheese, and proceed with the baking instructions. Note that you may need to add an extra 5 minutes to the total baking time if the meat base is cold when it goes into the oven.

Serving ideas

This casserole is best served hot, directly from the baking dish. Use a large metal spoon to scoop generous portions onto plates, ensuring each serving includes a good balance of the beef, peppers, biscuits, and melted cheese.

It pairs beautifully with a fresh garden salad or steamed green beans to add a crisp, light contrast to the rich and savory nature of the main dish. Serve immediately to enjoy the best texture and the signature cheese pull.

Because this dish is quite hearty, it serves well as a standalone main course. If you are hosting a larger group, you can easily double the recipe and bake two separate dishes to ensure everyone has plenty to eat.

Consider placing a small bowl of hot sauce or a side of sour cream on the table, as these condiments can complement the flavors of the Philly cheese steak ingredients and provide a nice touch for those who enjoy additional variety.
