Ingredients for Ultimate Philly Cheesesteak Grilled Cheese Bake

Philly Filling

• 1 cup yellow onion, diced
• 1/2 cup water
• 0.87 oz brown gravy mix packet
• 1 cup green bell pepper, diced
• 9 oz thinly sliced roast beef

Casserole Assembly

• 4 cups shredded mozzarella cheese
• 12 slices white or whole wheat bread
• 1/2 cup margarine or butter, softened

How to Make Ultimate Philly Cheesesteak Grilled Cheese Bake

Step 1: Prep and Start the Filling

Preheat oven to 400°F and grease a 9×13 inch baking dish. Cut roast beef slices into bite-sized pieces for easier eating and even flavor distribution in the casserole.

Step 2: Cook the Philly Mixture

In a large skillet over medium-high heat, melt butter or margarine. Add chopped roast beef, diced onions, and green peppers. Cook, stirring frequently, until onions are translucent and peppers begin to soften, about 5-7 minutes.

Step 3: Add the Gravy

Evenly sprinkle brown gravy mix over beef and vegetables, then pour in water. Stir until ingredients are coated with gravy. Remove from heat and set aside.

Step 4: Create the Bottom Layer

Spread 1/4 cup of margarine on 6 slices of bread. Cut each slice in half and arrange them margarine-side down in a greased baking dish. Sprinkle 2 cups of mozzarella cheese over the bread.

Step 5: Add the Filling and More Cheese

Evenly spread the roast beef mixture over the cheese layer, covering the bread completely. Top with the remaining 2 cups of mozzarella cheese for gooey, stretchy layers.

Step 6: Top and Bake

Spread margarine on the 6 slices of bread and cut them in half. Arrange margarine-side up on top of the casserole in a single layer. Bake for 26-30 minutes until the top bread is golden brown and the cheese is bubbly.

Step 7: Slice and Serve

Allow the casserole to rest for around 5 minutes before cutting into squares and serving while the cheese is still melted and gooey.

Storage Tips

Once the Philly Cheesesteak Grilled Cheese Casserole is prepared and baked, it is best served immediately while the cheese is still molten and the bread is crispy. Cut it into squares for easy serving, similar to lasagna. If you have leftovers, store them in an airtight container in the refrigerator for up to four days. When reheating, cover the casserole with foil and warm it in the oven at 350 degrees until heated through. Reheating in the oven helps maintain the crispiness of the bread, unlike when using a microwave.

For advanced preparation, you can assemble the entire casserole ahead of time, refrigerate it, and bake it when ready. If baking from a cold state, add a few extra minutes to the baking time. The flavors of the casserole actually improve when the components have time to meld together, making it a convenient make-ahead dish for gatherings or busy weeknights. Feel free to customize the casserole by adding ingredients like mushrooms to the vegetable mixture or experimenting with different cheese combinations to suit your preferences.

Ingredient Substitutions

If you need to make substitutions for this Philly cheesesteak grilled cheese casserole, there are a few options you can consider. If you prefer a different type of meat, you can swap the roast beef for thinly sliced cooked steak, chicken, or even plant-based alternatives such as seitan or tempeh for a different flavor profile. Just ensure the meat is thinly sliced and flavorful to maintain the essence of a classic Philly cheesesteak.

For those who may not have brown gravy mix on hand, you can substitute it with beef or vegetable broth mixed with a bit of cornstarch or flour to thicken it slightly. This will help provide the moisture and binding that the gravy mix adds to the casserole. Additionally, if you are looking to add more vegetables or change up the flavor profile, consider adding ingredients like mushrooms, cherry tomatoes, or different types of bell peppers for a twist on the classic recipe. These substitutions can help tailor the casserole to your preferences while maintaining the essence of a comforting Philly cheesesteak flavor.

Serving Suggestions

To serve this Philly Cheesesteak Grilled Cheese Casserole in a fun and interactive way, consider setting up a make-your-own casserole bar for a casual gathering. Prepare all the components – the roast beef, sautéed peppers and onions, brown gravy mix, shredded mozzarella cheese, and buttered bread slices – and let your guests assemble their own individual portions before baking. This not only adds an element of excitement but also allows everyone to customize their casserole to their liking, whether they prefer extra cheese, more veggies, or a spicier kick with some jalapeños.

For a more elegant presentation, serve the Philly Cheesesteak Grilled Cheese Casserole in individual ramekins or mini cast iron skillets. Layer the ingredients neatly in each vessel, starting with the buttered bread at the bottom, followed by the roast beef, sautéed peppers and onions, brown gravy mix, and a generous topping of shredded mozzarella cheese. Bake until bubbly and golden brown, then garnish with a sprinkle of fresh parsley or chopped chives for a pop of color. These individual portions not only look impressive but also make serving a breeze, allowing each guest to enjoy their own perfectly portioned Philly cheesesteak experience.

FAQs for Ultimate Philly Cheesesteak Grilled Cheese Bake

Yes, you can assemble this entire casserole hours ahead and refrigerate it until you’re ready to bake. Just remember to add a few extra minutes to the baking time if you’re starting with a cold casserole. The flavors actually improve when the components have time to meld together.

How do I ensure the vegetables don’t turn mushy when baking the casserole?

Can I customize this casserole with different ingredients?

Absolutely! While this version captures classic Philly flavors, you can customize it in various ways. Some popular additions include mushrooms in the vegetable mixture or using a combination of cheeses like provolone and mozzarella for more complex flavor.

How should I reheat leftovers of the Philly Cheesesteak Grilled Cheese Casserole?

To reheat leftovers, cover the casserole with foil and warm it in the oven at 350 degrees until heated through. This method will help maintain the crispy texture of the bread, unlike reheating in the microwave. Leftovers can be stored in the refrigerator for up to four days.
