Why You’ll Love This Recipe

I love this recipe because it’s fast, family-friendly, and perfect for feeding a crowd. It transforms a sandwich favorite into a satisfying, low-carb casserole without losing the flavors that make Philly cheesesteak such a hit. It’s also an excellent option for game days, weeknight dinners, or meal prep.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

1½ lb ground beef

2 bell peppers, chopped

½ onion, chopped

2 tsp minced garlic

1 tsp seasoned salt

8 slices provolone cheese

4 large eggs

¼ cup heavy whipping cream

2 tsp Worcestershire sauce

Directions

I preheat the oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.

In a large skillet over medium-high heat, I brown the ground beef until it’s no longer pink, breaking it up as it cooks.

Then I add the chopped bell peppers, onions, minced garlic, and seasoned salt to the skillet. I sauté everything for 4–5 minutes until the vegetables are soft.

I transfer the beef and vegetable mixture into the prepared baking dish and spread it evenly.

In a medium bowl, I whisk together the eggs, heavy cream, and Worcestershire sauce until the mixture is smooth.

I pour the egg mixture over the beef and vegetables in the dish.

Then I top it all with provolone cheese slices, arranging them to cover the surface.

I bake the casserole for 25–30 minutes, or until the eggs are set and the cheese is melted and slightly browned.

Variations

Use sliced steak instead of ground beef if I want a more authentic Philly cheesesteak texture.

Add mushrooms for extra umami and bulk.

Use mozzarella or cheddar if I don’t have provolone on hand.

Make it spicy with jalapeños or a pinch of crushed red pepper.

Try it with keto bread cubes mixed in for a more traditional casserole feel while staying low carb.

Storage/Reheating

I store leftovers in an airtight container in the fridge for up to 4 days. To reheat, I use the oven at 350°F for about 10–15 minutes or microwave individual portions for 1–2 minutes until heated through. This casserole also freezes well—just wrap tightly and thaw overnight in the fridge before reheating.

FAQs

What kind of beef works best for this casserole?

I prefer using ground beef for simplicity, but thinly sliced ribeye or sirloin steak also works if I want a more classic cheesesteak flavor.

Can I make this ahead of time?

Yes, I assemble everything up to the baking step, cover it, and refrigerate for up to 24 hours. Then I bake it fresh when ready to serve.

Is this casserole low carb?

Yes, it’s naturally low in carbs since there’s no bread or pasta involved. It’s great for keto or low-carb meal plans.

Can I use different cheese?

Absolutely. While provolone gives that signature Philly cheesesteak taste, I’ve also made it with mozzarella, cheddar, and even pepper jack for a kick.

How do I know when the casserole is done baking?

I check that the eggs are fully set (not jiggly in the center) and that the cheese is melted and slightly golden on top—usually around 25–30 minutes.

Conclusion

This Philly Cheesesteak Casserole is one of my go-to recipes when I want a comforting, easy-to-make dish that still packs big flavor. It’s simple, satisfying, and endlessly adaptable based on what I have on hand. Whether I’m cooking for the family or prepping meals for the week, it never disappoints.
