Step‑by‑Step Instructions for Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). As the oven warms up, prepare your 9×13 baking dish by spraying it generously with non-stick spray to prevent sticking. This small yet essential step will ensure your Philly Cheesesteak Casserole comes out beautifully intact and ready to serve.
Step 2: Sauté the Vegetables
In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the diced onion and bell peppers, sautéing for 5-6 minutes until they soften and become fragrant, stirring occasionally. Then, add 2 minced garlic cloves to the mix, stirring for an additional 30 seconds until the garlic is aromatic, which will elevate the flavors of your casserole.
Step 3: Brown the Ground Beef
Introduce 2 pounds of ground beef into the skillet, breaking it up with a spatula as it cooks. Continue cooking for about 7-8 minutes until the beef is fully browned and no longer pink. If necessary, drain any excess fat to ensure your Philly Cheesesteak Casserole has a nice balance and doesn’t become greasy.
Step 4: Add Flavor Enhancements
Once the meat is browned, stir in 2 tablespoons of Worcestershire sauce, which will add depth and richness to the mixture. Lower the heat, and fold in 8 ounces of softened cream cheese until the mixture is smooth and creamy; this step will help bind all the delicious components of your casserole together.
Step 5: Assemble the Casserole
Pour the meat and cream cheese mixture into your prepared baking dish, spreading it evenly across the bottom. Layer 8 ounces of torn provolone cheese directly over the beef mixture, followed by 1.5 cups of shredded mozzarella cheese sprinkled generously on top. This cheesy topping will create that classic comfort food experience!
Step 6: Bake Until Bubbly
Place the baking dish in your preheated oven and bake for 22-25 minutes. Keep an eye on it; the cheese should be melted, bubbly, and lightly golden on top, signaling that your Philly Cheesesteak Casserole is ready to delight your taste buds.
Step 7: Rest and Serve
After baking, take the casserole out of the oven and let it rest for about 5 minutes. This resting time allows the flavors to meld and helps prevent burns from the cheesey goodness. Once rested, serve this hearty Philly Cheesesteak Casserole to your family and enjoy their delighted reactions!

Expert Tips for Philly Cheesesteak Casserole
-
Choose Quality Beef: Use high-fat ground beef (80/20) for the best flavor and tenderness. Leaner meat can lead to a dry casserole.
-
Don’t Rush the Sauté: Sauté the onions and peppers until completely softened; this enhances their sweetness and depth. A quick cook won’t do them justice.
-
Properly Incorporate Cheese: Ensure your cream cheese is fully softened before mixing to create a smooth, creamy base that binds the casserole without lumps.
-
Layer for Flavor: When layering cheese on top, try mixing provolone with mozzarella for a flavorful combination that melts beautifully and offers that signature cheesesteak experience.
-
Rest Before Serving: Allow the casserole to sit for about 5 minutes after baking. This resting period helps set the layers and prevents gooey spills when you serve.

Philly Cheesesteak Casserole Recipe FAQs
How do I choose the right ground beef for this casserole?
Absolutely! For the best flavor and tenderness, go for ground beef with an 80/20 fat ratio. This higher fat content ensures a juicy and rich taste, making your Philly Cheesesteak Casserole truly satisfying. Leaner cuts can lead to a dryer casserole, so don’t skimp on the fat.
What’s the best way to store leftovers?
Very important! To keep your Philly Cheesesteak Casserole fresh, store leftovers in an airtight container in the refrigerator. It will stay delicious for up to 4 days, allowing you to enjoy this comforting meal multiple times. Just remember to allow it to cool completely before sealing to prevent moisture buildup.
Can I freeze the casserole? What’s the best method?
Absolutely! You can freeze individual portions of your casserole for up to 3 months. Here’s how: Allow the casserole to cool completely, then cut it into servings and wrap each portion tightly in plastic wrap. Place them in airtight containers or heavy-duty freezer bags, ensuring to remove as much air as possible. When you’re ready to enjoy, thaw it in the refrigerator overnight, and reheat in the oven for the best texture.
What if my casserole turns out too watery or greasy?
Common issue! If your casserole seems watery, it could be due to excess moisture from the vegetables or beef. To prevent this, ensure you properly sauté your onions and bell peppers until they are fully softened and moisture has evaporated. If you notice grease pooling on top after baking, try using higher fat ground beef but remember to drain excess fat before baking for optimal results.
Is this recipe suitable for families with dietary restrictions?
Definitely! While the Philly Cheesesteak Casserole is naturally low-carb and packed with protein, it does contain dairy.
