Philly Cheesesteak Casserole Ingredients

Philly Cheesesteak Casserole raw ingredients that are labeled

Our Philly cheesesteak casserole recipe calls for a selection of fresh, flavorful ingredients that come together to create a dish that’s both satisfying and delicious.

In this recipe, seasoned ground beef mingles with caramelized onions, green and red bell peppers, and a touch of Worcestershire sauce.

The cream cheese adds a creamy and tangy element, enhancing the overall richness. The provolone and mozzarella cheese form a luscious and melty layer on top, providing a golden and cheesy finish.

Here’s what you’ll need:

2 pounds of ground beef
1 green bell pepper, thinly sliced
1 red bell pepper, thinly sliced
1 large onion, thinly sliced
2 tablespoons of Worcestershire sauce
1 teaspoon of salt
1 teaspoon of black pepper
4 ounces of cream cheese, softened
¼ cup of beef broth
1 cup of shredded mozzarella cheese
8 provolone cheese slices
Fresh parsley (chopped)

PRO TIP:

Choose lean ground beef for this recipe to avoid excessive greasiness. Ground beef with a 90% lean to 10% fat ratio is a good option.

Substitutions and Additions

GROUND BEEF: If you prefer leaner meat, ground turkey or chicken can be used. For a vegetarian version, consider using a meat substitute like ground soy or lentils.

BELL PEPPERS: Feel free to use any color of bell peppers you prefer or have on hand. You can also add other vegetables like mushrooms or zucchini for added flavor.

CHEESE: While the recipe suggests provolone and mozzarella cheese, you can experiment with other types, such as cheddar, Swiss, or a cheese blend that melts well.

WORCESTERSHIRE SAUCE: If you don’t have Worcestershire sauce, you can substitute it with soy sauce or a mixture of soy sauce and vinegar for a similar tangy, umami flavor.

How To Make This Philly Cheesesteak Casserole Recipe

The Philly cheesesteak casserole is a simple and delicious dinner option that can be ready in less than an hour.

STEP ONE: Preheat the oven to 375°F (190°C). Grease a 9×13-inch casserole dish with nonstick cooking spray.

STEP TWO: In a large skillet over medium heat, cook the ground beef until browned and fully cooked. Once cooked, transfer the beef to a bowl and set it aside.

STEP THREE: Add the green peppers, red peppers, and onion in the same skillet. Sauté them until they become tender and slightly caramelized, about 5-7 minutes.

STEP FOUR: Add the cooked ground beef back into the skillet with the sautéed peppers and onions. Stir in the Worcestershire sauce, salt, and pepper. Cook for an additional 2-3 minutes to allow the flavors to meld together.

PRO TIP:

Adjust the amount of salt, pepper, and Worcestershire sauce to your taste. Start with the suggested measurements, and add more if desired.

STEP EIGHT: Cover the baking dish with foil and bake in the preheated oven for 20 minutes. Then remove the foil and continue baking for another 10 minutes or until the cheese is melted and bubbly and the casserole is heated through.

PRO TIP:

Oven temperatures vary and may need to be recalibrated periodically to ensure they are accurate. Make sure to keep a close eye on your casserole as the suggested baking time approaches.

STEP NINE: Once the casserole is done, remove it from the oven and let it cool for a few minutes.

PRO TIP:

Allow the casserole to cool for a few minutes after removing it from the oven. This will help the flavors settle and make it easier to serve.

STEP TEN: Garnish with fresh parsley and serve.

Storage

MAKE AHEAD: You can assemble the casserole ahead of time and refrigerate it until ready to bake. Cover it tightly with foil or plastic wrap and store it in the refrigerator for up to 24 hours.

This casserole is also a great option for meal prep. You can make it ahead of time and reheat portions throughout the week for quick and easy meals.

Store the casserole in an airtight container or cover the baking dish tightly with foil or plastic wrap. It will keep in the fridge for up to 4 days.

IN THE FREEZER: This casserole freezes well. Once cooled, cut the leftover casserole into individual portions and store them in airtight containers or freezer-safe bags.
