Philly Cheesesteak Grilled Cheese (Printer-Friendly Version)

Layers of buttery bread, beef, peppers, and cheese create the ultimate comfort food with classic Philly flavors.

# Required Ingredients:

→ Main Components

01 - 450 g thinly sliced deli-style roast beef
02 - 1 large yellow onion, diced
03 - 1 large green bell pepper, diced
04 - 2 packets (approx. 56 g) brown gravy mix
05 - 480 ml water

→ Cheese and Bread

06 - 4 cups (400 g) shredded mozzarella cheese
07 - 12 slices sturdy white or wheat sandwich bread
08 - 120 g margarine or unsalted butter, softened

# Step-by-Step Instructions:

01 - Chop the roast beef slices into small, bite-sized pieces to ensure even distribution throughout the casserole.
02 - Heat a large skillet over medium-high heat and melt a portion of the margarine. Add chopped roast beef and sauté for 1 minute to warm through. Add diced onion and green bell pepper, cooking for 5 to 7 minutes while stirring, until onions are translucent and peppers are just beginning to soften.
03 - Sprinkle brown gravy mix over the beef and vegetables, then add water. Stir continuously until all components are well coated and the mixture appears glossy and cohesive. Remove from heat and allow to cool slightly.
04 - Spread about 60 g of margarine on six bread slices. Cut each slice in half and arrange margarine-side down to fully cover the bottom of a greased 23 x 33 cm baking dish.
05 - Distribute half of the shredded mozzarella cheese evenly on top of the bread layer. Spoon the beef and vegetable mixture over the cheese, spreading evenly to cover the surface.
06 - Sprinkle the remaining mozzarella cheese over the beef mixture for a substantial cheesy layer.
07 - Spread the remaining 60 g of margarine on the last six slices of bread. Cut each in half and arrange margarine-side up, overlapping if needed to completely cover the surface.
08 - Bake in a preheated oven at 205°C for 26 to 30 minutes, or until the top bread layer is golden brown and the cheese is bubbling at the edges.
09 - Remove from oven and let rest briefly before cutting into squares. Serve hot for optimal texture and flavor.

# Handy Cooking Tips:

01 - Undercook the vegetables slightly in the pan, as they will continue cooking during baking and retain a pleasing texture.
02 - Allow the filling to cool slightly before assembly; hot filling can cause the bottom bread layer to become soggy.
03 - Ensure bread slices are arranged without gaps for uniform browning and optimal structure.
04 - This dish can be assembled up to several hours in advance and refrigerated before baking; add additional baking time when starting from cold.
05 - Leftovers retain their quality best when reheated in the oven instead of a microwave to preserve crispness.
