Instructions

Preheat Oven: Preheat the oven to 350°F to ensure it’s ready for baking the casserole.
Cook Beef and Onion: In a skillet over medium heat, cook the ground beef and diced onion until the meat is browned and fully cooked. Drain excess fat to keep the dish from being greasy.
Mix Beef with Sauces: In a bowl, combine the cooked beef and onions with mayonnaise, ketchup, mustard, salt, and pepper. Stir well to create the flavorful Big Mac sauce mixture.
Assemble Casserole Base: Spread the beef mixture evenly into a baking dish to form the base layer of the casserole.
Add Toppings: Layer the shredded cheddar cheese over the beef mixture, then add shredded lettuce, diced pickles, diced tomatoes, and diced onions evenly on top.
Sprinkle Sesame Seeds: Evenly sprinkle sesame seeds on top to mimic the classic burger bun look and add a subtle nutty flavor.
Bake: Place the assembled casserole in the preheated oven. Bake for 20-25 minutes or until heated through and the cheese is melted and bubbly.
Serve Hot: Remove from the oven and serve immediately for the best flavor and texture. Enjoy your Big Mac casserole!

Notes

To reduce fat, use lean ground beef or turkey.
For a spicier twist, add a dash of hot sauce to the beef mixture.
Fresh lettuce should be added just before serving to keep it crisp.
Sesame seeds are optional but provide an authentic touch reminiscent of a Big Mac bun.
This casserole can be prepared in advance and baked just before serving.
