A decadent baked burger fusion combining thin-sliced ribeye steak, sautéed peppers, onions, homemade creamy cheese sauce, and gooey mozzarella inside golden sesame buns.
This inventive recipe brings together the classic flavors of a Philadelphia cheesesteak and a cozy casserole burger bake. Tender ribeye is seared with aromatic onions and green peppers, enriched with butter and spices, and layered inside soft burger buns before being crowned with a double layer of melted cheese and baked to golden perfection.
Ingredients
- 4 burger buns
- 400 g ribeye steak
- 3 slices cheese
- 2 tbsp milk
- 1 onion
- 1 green pepper
- 1 piece butter
- 1 cup mozzarella cheese
- 2 tbsp yellow mustard sauce
- 1 tbsp cooking oil
- 1 pinch chili powder
- 1 pinch sea salt
- 1 pinch black pepper
- optional coriander
Instructions
- 1Arrange burger buns

Slice the burger buns in half and arrange the bottom halves in a grey baking dish to prepare them for filling and baking.
Tip: Make sure the baking dish is clean and dry before placing the buns inside. - 2Prepare cheese sauce

Take three slices of cheese, add a little milk, and microwave them until melted to create a smooth cheese sauce. Stir the mixture thoroughly in a ceramic jug until well combined.
Tip: Heat the cheese and milk in short intervals in the microwave to prevent burning or separating. - 3Spread Cheese Sauce on Buns

Pour and spread the prepared creamy cheese sauce evenly over the sliced burger buns placed inside the baking dish.
Tip: Ensure the sauce covers the surface of the buns well to keep them moist and flavorful during baking. - 4Slice the Ribeye Steak

Place the ribeye steak on a cutting board and use a sharp knife to slice it into thin, even strips.
Tip: Slicing the beef thinly ensures quick and even cooking when stir-frying later. - 5Chop Onions and Green Peppers

Place the onions and green peppers on a cutting board and chop them into thin slices or strips to use as side vegetables.
Tip: Uniform slicing allows the vegetables to soften quickly and blend well with the beef. - 6Stir-fry Onions and Peppers

Heat cooking oil in a pan over medium heat, then add the chopped onions and green peppers, stirring until they become soft.
Tip: Cook until translucent to bring out their natural sweetness before adding the meat. - 7Sauté beef with vegetables and butter

Melt a piece of butter in a pan alongside the previously stir-fried onions and green peppers, then add the sliced ribeye beef and stir-fry briefly.
Tip: Ensure the pan is adequately hot before adding the butter and beef to achieve a nice sear. - 8Season the meat and vegetables

Sprinkle chili powder, sea salt, and black pepper directly into the pan over the mixture of beef, onions, and green peppers, tossing to distribute the spices evenly.
Tip: Season to taste, keeping in mind that the cheese sauce and slices will also add saltiness. - 9Melt cheese over the mixture

Cover the stir-fried meat and vegetable mixture in the pan with cheese slices, and simmer on low heat until the cheese completely melts into the ingredients.
Tip: Cover the pan with a lid if necessary to trap the heat and speed up the melting process. - 10Assemble the burger filling

Spoon and spread the cooked meat, vegetable, and melted cheese mixture evenly over the burger buns prepared earlier in the baking dish.
Tip: Distribute the filling evenly across all bun halves to ensure every bite is well-balanced. - 11Sprinkle mozzarella cheese

Evenly sprinkle a generous layer of shredded mozzarella cheese over the top of the beef and vegetable filling in the baking dish to create a rich and gooey texture when baked.
Tip: Distribute the cheese evenly across the entire surface so every portion gets a nice cheese pull. - 12Add yellow mustard sauce

Squeeze yellow mustard sauce in a zig-zag pattern directly over the layer of shredded mozzarella cheese to add a tangy kick that cuts through the richness of the meat and cheese.
Tip: A zig-zag drizzle ensures the mustard flavor is balanced across the dish rather than clumped in one spot. - 13Place top burger buns

Carefully place the top halves of the sesame seed burger buns over the assembled filling inside the baking dish, pressing down gently to fit them snugly.
Tip: Ensure the buns cover the filling evenly to trap the moisture and melt the cheeses together underneath during baking. - 14Brush oil on burger buns

Lightly brush cooking oil across the surface of the burger buns to help them achieve a golden-brown, shiny finish and a crisp exterior while baking.
Tip: A light coating is enough; avoid soaking the buns so they dont become soggy. - 15Garnish with coriander

Sprinkle freshly chopped coriander evenly over the oiled burger buns to introduce a fresh herbal note and a pop of color to the bake.
Tip: Add the coriander before baking so the herbs release their aroma into the warm buns. - 16Cover with aluminum foil

Cover the baking dish tightly with a sheet of aluminum foil to lock in moisture and prevent the buns and toppings from over-browning too quickly in the oven.
Tip: Crimp the edges of the foil securely around the rim of the baking dish to create a good seal.
