How to Make Philly Cheesesteak Casserole
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish with cooking spray or a small amount of olive oil.
Preparing the dish in advance makes assembly easier and helps prevent the casserole from sticking.
Step 2: Brown the Ground Beef
Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook for 6–8 minutes, breaking it apart with a wooden spoon, until browned and cooked through.
Drain excess fat if necessary, leaving a little in the pan for flavor. Stir in the Worcestershire sauce, paprika, Italian seasoning, salt, and black pepper.
Transfer the beef to a bowl and set aside.
Step 3: Sauté the Vegetables
Using the same skillet, add the sliced onion, bell peppers, and optional mushrooms. Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables soften and the onions begin to turn golden.
Add the minced garlic and cook for another 30 seconds. Avoid browning the garlic too much, as it can become bitter.
Step 4: Make the Creamy Sauce
Reduce the heat to low. Add the softened cream cheese and beef broth to the skillet. Stir until the cream cheese melts into a smooth sauce.
Return the cooked beef to the skillet and mix well with the vegetables. If the mixture looks too thick, add a small splash of beef broth. Taste and adjust the seasoning as needed.
Step 5: Assemble the Casserole
Transfer the beef and vegetable mixture into the prepared baking dish. Spread it evenly, then sprinkle the shredded provolone and mozzarella over the top.
For a more traditional Philly cheesesteak flavor, arrange additional provolone slices over the shredded cheese.
Step 6: Bake Until Bubbly
Place the dish in the preheated oven and bake uncovered for 15–20 minutes, or until the cheese is melted, bubbling, and lightly golden in spots.
If you prefer a deeper golden cheese topping, broil for 1–2 minutes at the end, watching carefully to prevent burning.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for about 5 minutes before serving. This allows the sauce to settle slightly and makes serving easier.
Spoon generous portions onto plates and enjoy the combination of savory beef, tender vegetables, and melted cheese.
Tips for the Best Philly Cheesesteak Casserole
- Choose the right beef: Ground beef makes this recipe affordable and easy, while thinly sliced steak gives it a more traditional cheesesteak texture.
- Use freshly shredded cheese: Cheese shredded from a block often melts more smoothly than pre-shredded varieties.
- Cook off excess moisture: Let the vegetables release their moisture in the skillet before adding the cream cheese. This helps prevent a watery casserole.
- Season gradually: Worcestershire sauce and cheese already add savory flavor, so taste the mixture before adding extra salt.
- Don’t overbake: Once the cheese has melted and the casserole is bubbling, it is ready. Excessive baking can make the beef dry.
- Let it rest: A few minutes of resting makes the casserole easier to portion.
Delicious Variations
Philly Cheesesteak Casserole with Steak
Replace the ground beef with 1½ pounds of thinly sliced ribeye or sirloin. Sear the steak in batches over high heat until browned, then set aside while you cook the vegetables. Return the steak to the pan before assembling the casserole. Avoid overcrowding the skillet so the meat browns rather than steams.
Low-Carb Philly Cheesesteak Casserole
This recipe is naturally low in carbohydrates when served without bread, rice, or pasta. Check the labels on your broth and seasonings if you are following a specific low-carb or ketogenic meal plan.
Philly Cheesesteak Casserole with Pasta
For a more filling family dinner, stir in 8 ounces of cooked pasta before transferring the mixture to the baking dish. Penne, rotini, and egg noodles all work well. You may need a little extra broth to keep the casserole creamy.
Add More Vegetables
Sliced mushrooms, zucchini, or extra bell peppers are easy additions. Cook vegetables until most of their excess moisture has evaporated before combining them with the sauce.
Make It Spicy
Add crushed red pepper flakes, diced jalapeños, or a little hot sauce to the beef mixture for a spicy twist.
What to Serve with Philly Cheesesteak Casserole
This cheesy beef casserole pairs well with a variety of simple side dishes:
- A crisp green salad with vinaigrette
- Roasted broccoli or green beans
- Garlic bread or toasted hoagie rolls
- Steamed rice or mashed potatoes
- Roasted potatoes
- Coleslaw or a cucumber salad
For a cheesesteak-inspired meal, serve the casserole with toasted rolls so everyone can scoop the beef, vegetables, and melted cheese into their own sandwich.
Make-Ahead, Storage, and Reheating
Make ahead: Prepare the beef and vegetable mixture up to one day in advance, refrigerate it in a covered container, and assemble the casserole with the cheese shortly before baking. If assembling the entire casserole ahead, keep it refrigerated and allow extra baking time if it is still cold.
Refrigeration: Store leftovers in an airtight container in the refrigerator for 3–4 days.
Reheating: Warm individual portions in the microwave, or cover the baking dish with foil and heat in a 350°F (175°C) oven until hot throughout. The center should reach 165°F (74°C) when reheating leftovers.
Freezing: Freeze cooled portions in freezer-safe containers for up to 2–3 months for best quality. Thaw overnight in the refrigerator before reheating. The cream cheese sauce may change texture slightly after freezing, but stirring the reheated mixture can help bring it together.
Frequently Asked Questions
What cheese is best for Philly Cheesesteak Casserole?
Provolone is a classic choice because it melts well and has a mild, savory flavor. Mozzarella adds extra stretchiness, while American cheese can create a softer, creamier topping.
Can I use steak instead of ground beef?
Yes. Thinly sliced ribeye or sirloin gives the casserole a more traditional Philly cheesesteak flavor. Slice the meat thinly against the grain and sear it quickly to keep it tender.
How do I prevent the casserole from becoming watery?
Cook the vegetables until their excess moisture evaporates, drain excess fat from the beef, and avoid adding too much broth. Letting the casserole rest after baking also helps it set.
Can I make this casserole without cream cheese?
Yes. Replace the cream cheese and broth mixture with approximately ½ cup of heavy cream, or omit the creamy sauce for a simpler beef-and-cheese casserole. The texture will be different, but the dish will still be flavorful.
Is Philly Cheesesteak Casserole good for meal prep?
Absolutely. Divide the cooked casserole into individual portions and refrigerate them for easy lunches or dinners. Reheat each portion until hot throughout.
