  • 1 red bell pepper, diced
  • 3 cloves garlic, minced
  • 1 teaspoon salt
  • ½ teaspoon black pepper

  • 1 cup shredded provolone cheese
  • 2 tablespoons chopped fresh parsley

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 and set it aside.

Step 2: Brown the Ground Beef

Heat a large skillet over medium-high heat.

Add the ground beef and cook, breaking it apart with a wooden spoon, until browned and cooked through.

Drain any excess grease if necessary.

Step 3: Cook the Vegetables

Add the diced onion and bell peppers to the skillet with the beef.

Cook for approximately 5–7 minutes, stirring occasionally, until the vegetables begin to soften.

Add the minced garlic and cook for another 30 seconds until fragrant.

Step 4: Season the Beef Mixture

Add the salt, black pepper, Italian seasoning, and Worcestershire sauce.

Stir everything together until the beef and vegetables are evenly seasoned.

Step 5: Add the Cream Cheese

Reduce the heat to medium-low.

Add the softened cream cheese and stir until it melts into the beef mixture and creates a creamy consistency.

Continue stirring until everything is evenly combined.

Step 6: Transfer to the Baking Dish

Spoon the beef mixture into the prepared baking dish.

Spread it evenly across the dish.

Step 7: Add the Cheese

Sprinkle the shredded mozzarella and provolone evenly over the top.

Make sure the cheese covers the surface for a deliciously golden and bubbly finish.

Step 8: Bake

Place the casserole in the preheated oven and bake for approximately 15–20 minutes, or until the cheese is completely melted and bubbling.

For a more golden top, place the casserole under the broiler for 1–2 minutes at the end, watching carefully so the cheese doesn't burn.

Step 9: Garnish and Serve

Remove the casserole from the oven and let it rest for a few minutes.

Sprinkle with fresh chopped parsley and serve warm.

What Makes This a Philly Cheesesteak Casserole?

A classic Philly cheesesteak is known for its combination of beef, onions, peppers, and melted cheese. This casserole takes those familiar flavors and transforms them into a simple baked dish.

Instead of thinly sliced steak, this version uses ground beef for convenience and affordability. The combination of provolone and mozzarella gives the casserole a rich, gooey cheese topping.

Tips for the Best Cheesesteak Casserole

  • Don't overcrowd the skillet when browning the beef.
  • Cook the vegetables until tender but not mushy.
  • Use softened cream cheese so it blends easily.
  • Freshly shredded cheese melts especially well.
  • Allow the casserole to rest for a few minutes before serving.
  • Don't overbake once the cheese has melted.

What Kind of Cheese Is Best?

Provolone is one of the most traditional choices for cheesesteak-inspired recipes because it has a mild, slightly tangy flavor and melts beautifully.

Mozzarella adds extra stretch and creaminess. You can also experiment with white American cheese, cheddar, or Monterey Jack.

Can I Use Steak Instead of Ground Beef?

Absolutely. Thinly sliced steak can be used for a more traditional cheesesteak flavor.

Ribeye is a popular choice because of its tenderness and rich flavor. Slice the steak very thinly against the grain and cook it quickly before combining it with the vegetables.

Can You Make This Casserole Ahead?

Yes. Prepare the beef and vegetable mixture and transfer it to the baking dish.

How to Store Leftover Cheesesteak Casserole

Allow leftovers to cool before transferring them to an airtight container.

Refrigerate and enjoy within a few days.

Individual portions are convenient for quick lunches or dinners.

How to Reheat Philly Cheesesteak Casserole

Freeze in individual portions for convenient meals.

Thaw overnight in the refrigerator before reheating thoroughly.

Frequently Asked Questions

Can I use ground turkey?

Yes. Ground turkey can replace ground beef for a lighter variation. Because turkey is leaner, you may want to add a little extra olive oil or sauce for moisture.

Can I make this casserole without cream cheese?

Yes. Cream cheese adds richness and creaminess, but you can omit it for a simpler beef, vegetable, and cheese casserole.

Can I add mushrooms?

Absolutely. Mushrooms are a delicious addition and pair especially well with beef, onions, peppers, and provolone.

What cheese melts best for this recipe?

Provolone and mozzarella are excellent choices. White American cheese, Monterey Jack, and cheddar can also be used.

Can I make this recipe with sliced steak?

Yes. Thinly sliced ribeye or another tender steak can be used instead of ground beef for a more traditional cheesesteak experience.

How do I keep the casserole from becoming watery?

Cook the vegetables until excess moisture has evaporated before assembling the casserole. Also avoid adding too much liquid to the beef mixture.
