• Onion- Adds sweetness and savory depth that helps the casserole taste more like a classic burger.
• Garlic- Adds bold flavor and rounds out the savory richness of the beef.
• Cream Cheese- Helps create a creamy texture in the casserole and blends beautifully with the beef and cheese.
• Cheddar Cheese- Brings that classic cheeseburger flavor and melts beautifully over the casserole.
• Mozzarella Cheese- Adds extra melty richness and helps create that irresistible cheesy top layer.
• Pickles- A must for that Big Mac-inspired tangy bite. Chopped dill pickles mixed into or on top of the casserole add a classic burger flavor.
• Mustard- Adds that familiar burger tang and helps flavor both the filling and the sauce.
• Mayonnaise- A key part of the creamy special sauce flavor.
• Sugar-Free Ketchup or Ketchup- Adds a little sweetness and burger-style tomato flavor to the sauce.
• Paprika- Adds mild warmth and a little depth to the special sauce.
• Salt- Enhances all the savory flavors in the casserole.
• Black Pepper- Adds warmth and balance.
• Shredded Lettuce- Optional for serving, but it gives the finished casserole that classic Big Mac-inspired topping.
• Sesame Seeds- Optional, but a sprinkle on top can give the casserole even more burger character.

Cook the Beef Mixture. In a large skillet, cook the ground beef and onion until the beef is browned and the onions are softened. Add the garlic and cook briefly until fragrant.

Make It Creamy. Stir in the cream cheese and part of the shredded cheese until the mixture is creamy and well combined. Season with salt and black pepper.

Prepare the Special Sauce. In a small bowl, mix together the mayonnaise, ketchup, mustard, paprika, and a little chopped pickle if desired. This gives the casserole that unmistakable burger-style sauce flavor.

Layer the Casserole. Transfer the beef mixture to a baking dish. Spoon or drizzle some of the special sauce over the top, then add the remaining shredded cheese. Bake until the cheese is melted, bubbly, and lightly golden.

Top and Serve. Once baked, top with chopped pickles, shredded lettuce, extra special sauce, and sesame seeds if desired for the full Big Mac-inspired effect.

Making Big Mac casserole is simple, and these tips can help make it even better:

• Drain Excess Grease. If your beef releases a lot of grease, draining some off helps keep the casserole rich without becoming oily.
• Use Sharp Cheddar for More Flavor. Sharp cheddar gives the casserole an even more pronounced cheeseburger taste.
• Chop the Pickles Small. Small pickle pieces distribute more evenly and make each bite more balanced.
• Add the Lettuce After Baking. Fresh shredded lettuce is best added right before serving so it stays crisp.
• Do Not Skip the Sauce. The special sauce is what really makes the casserole taste Big Mac-inspired rather than just cheeseburger-flavored.
