Ingredients You’ll Need

• Bell peppers: Green, red, or a mix. These add sweetness, crunch, and that unmistakable cheesesteak flavor.
• Onion: Sautéed until soft and golden, onion adds depth and sweetness.
• Garlic: Minced garlic brings a punch of aromatic flavor that makes everything pop.
• Cream cheese: For creaminess and a touch of tang—this gives the casserole its luscious texture.
• Worcestershire sauce: Just a splash adds a rich umami boost that ties all the flavors together.
• Salt and pepper: Basic seasonings to balance and enhance the flavors.
• Mozzarella cheese: Melts beautifully and helps bind everything together with gooey goodness.
• Provolone cheese: Classic cheesesteak cheese—melts creamy and gives that authentic flavor.
• Eggs: Helps hold the casserole together while baking, especially if skipping a bread or pasta base.

Variations

Want to put your own spin on this casserole? Here are a few tasty twists:

• Low-Carb Version: Skip any bread or noodles entirely—this dish holds up great on its own as a keto-friendly bake.
• Add Pasta or Rice: Mix in cooked penne or rice if you’re craving some carbs for a heartier dish.
• Switch the Protein: Try thin-sliced steak instead of ground beef, or even use ground turkey for a lighter take.
• Spicy Style: Toss in a few jalapeños or red pepper flakes if you like it hot.
• Mushroom Lover’s Dream: Sautéed mushrooms blend beautifully with the beef and cheese for an earthy, rich flavor.

How to Make Easy Philly Cheese Steak Casserole

Step 1: Sauté the Veggies

Start by heating a bit of oil in a skillet and cooking the onions and bell peppers until they’re softened and just beginning to caramelize. Add in the garlic and cook for another minute until fragrant.

Step 2: Brown the Beef

Add your ground beef to the skillet and break it up with a spatula as it browns. Once it’s fully cooked, drain off any excess grease.

Step 3: Add Flavor

Stir in the Worcestershire sauce, salt, pepper, and cream cheese. Let it melt into the mixture, stirring until everything is creamy and well combined.

Step 4: Assemble the Casserole

Spread the beef and veggie mixture evenly into a greased baking dish. In a small bowl, whisk the eggs and pour them evenly over the beef layer—this helps set the casserole while it bakes.

Step 5: Add Cheese

Top the entire casserole with shredded mozzarella and slices of provolone. Be generous—this is what gives you that gooey, bubbly, irresistible top layer.

Step 6: Bake

Bake at 375°F for about 20–25 minutes, or until the cheese is melted, golden, and bubbly.

Pro Tips for Making the Recipe

• Use freshly shredded cheese: It melts better and doesn’t have the anti-caking agents that pre-shredded cheeses do.
• Drain the beef well: You want the casserole to be creamy, not greasy—don’t skip draining the fat.
• Let it rest before serving: Give the casserole 5–10 minutes to set after baking. This helps it slice neatly and keeps the layers intact.
• Add a crunchy topping: Sprinkle a few breadcrumbs or crushed crackers on top before baking if you want a little crunch.

How to Serve

This casserole is a meal all on its own, but if you want to round it out, here are a few delicious ideas:

On the Side:

• Serve with a crisp green salad tossed in a tangy vinaigrette to balance the richness.
• Roasted or steamed veggies like broccoli, green beans, or asparagus make a perfect light side.

Sandwich Style:

• Spoon the casserole into hoagie rolls or sub buns for a Philly cheesesteak sandwich twist.

With a Dip:

• A drizzle of chipotle mayo, spicy mustard, or even a creamy ranch dip on top adds a zippy touch.

Make Ahead and Storage

Storing Leftovers

Once cooled, store any leftover casserole in an airtight container in the fridge for up to 4 days.

Freezing

This casserole freezes well! Wrap tightly in foil and store in a freezer-safe container for up to 3 months. Thaw in the fridge overnight before reheating.

Reheating

Reheat in the microwave for a quick meal or in the oven at 350°F until warmed through and bubbly again. Add a little extra cheese on top before reheating for bonus melty magic.

FAQs

Can I use steak instead of ground beef?
Absolutely. Thinly sliced ribeye or sirloin gives you a more authentic Philly cheesesteak flavor. Just sear the slices quickly before adding to the dish.

Is this recipe low-carb or keto?
Yes! This casserole is naturally low in carbs if you skip pasta or bread, making it great for keto diets. Just check your Worcestershire sauce and cream cheese for hidden sugars.

Can I prepare this ahead of time?
Yes, assemble the casserole up to a day ahead, cover tightly, and refrigerate. Just add 5–10 minutes to the baking time if cooking straight from the fridge.

What’s the best cheese for a Philly cheesesteak casserole?
Provolone is the go-to for that classic flavor, but mozzarella adds great meltiness. A little cheddar or pepper jack can be added for variety.
