How to Make Philly Cheesesteak Casserole

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch casserole dish and set aside.

Step 2: Sauté the Meat and Vegetables

  • In a large skillet over medium heat, cook the ground beef or shaved steak until browned. Drain excess fat.
  • Add diced onion, bell peppers, mushrooms, and garlic. Cook for about 5–7 minutes, until the veggies are soft and fragrant.
  • Stir in salt, black pepper, smoked paprika, and Worcestershire sauce. Cook another minute, then remove from heat.

Step 3: Prepare the Creamy Egg Mixture

In a medium bowl, whisk together:

  • Softened cream cheese
  • Mayonnaise
  • Eggs

This creamy blend acts as a rich and fluffy binder, giving the casserole its luscious texture.

Step 4: Assemble the Casserole

  • In the prepared baking dish, spread the beef and veggie mixture evenly across the bottom.
  • Pour the cream cheese-egg mixture over the meat, spreading it gently with a spatula to cover evenly.
  • Sprinkle the top with shredded provolone and mozzarella cheese.

Step 5: Bake to Golden, Cheesy Goodness

Bake in the preheated oven for 30–35 minutes, or until the top is golden and bubbly, and the casserole is set in the center.

Let cool for about 5 minutes before serving. This helps the layers firm up and enhances the flavor.

Serving Suggestions

This Philly Cheesesteak Casserole is a meal on its own, but here are a few sides to round out your dinner:

  • Caesar salad or simple garden salad
  • Garlic roasted broccoli or green beans
  • Cauliflower mash for a low-carb option
  • Crusty bread or garlic toast (if not avoiding carbs)

Make-Ahead and Storage Tips

To Make Ahead:

Assemble the casserole up to a day in advance and refrigerate. When ready to cook, bake as directed—add an extra 5 minutes if baking from chilled.

To Store Leftovers:

  • Store in an airtight container in the fridge for up to 4 days.
  • Reheat in the microwave or oven until warmed through.

To Freeze:

Freeze the fully baked casserole (cooled) in portions or whole. Thaw overnight in the fridge and reheat in the oven at 325°F until heated through.

Recipe Variations

Want to tweak it to fit your preferences? Try these tasty variations:

  • Use chicken or turkey instead of beef for a leaner version.
  • Add jalapeños or hot sauce for a spicy kick.
  • Top with crispy fried onions after baking for extra crunch.
  • Add cream of mushroom soup to the filling for a deeper, richer flavor.
  • Use sliced steak or roast beef leftovers for an authentic texture.

Why This Casserole Stands Out

  • It captures the classic Philly Cheesesteak flavor in an easy-to-eat format.
  • It’s low in carbs, but high in satisfaction.
  • The combination of cream cheese, provolone, and mozzarella creates a deeply comforting bite.
  • It’s family-approved and crowd-pleasing.

Frequently Asked Questions

Can I use a different cheese?

Yes! Try white American, cheddar, gouda, or a provolone/mozzarella mix depending on your taste.

Is this casserole keto-friendly?

Yes, it’s low-carb and keto-approved when served without bread.

Can I skip the eggs?

Eggs help bind the casserole and provide structure, but if needed, you can use a small amount of almond flour or omit—the texture will be creamier, less firm.
