How to Make Big Mac Casserole

Ingredients

2 lbs ground beef (I use 80/20 for that authentic fast food flavor)
1 medium onion, finely diced (about 1 cup)
3 cloves garlic, minced (or more, I won’t judge)
2 tablespoons Worcestershire sauce
1 tablespoon yellow mustard
1 teaspoon salt
1/2 teaspoon black pepper
1 teaspoon garlic powder
1 teaspoon onion powder
6 hamburger buns, torn into bite-sized pieces (stale ones actually work better!)
2 tablespoons butter, melted
1 teaspoon sesame seeds
1/2 teaspoon garlic powder
1 cup mayonnaise (full fat is best here)
1/4 cup ketchup
2 tablespoons sweet pickle relish (the secret ingredient!)
1 tablespoon yellow mustard
1 tablespoon white vinegar
1 teaspoon sugar
1 teaspoon paprika
1/2 teaspoon garlic powder
1/2 teaspoon onion powder
2 cups shredded cheddar cheese (the orange kind for that classic look)
1 cup shredded lettuce
1/2 cup dill pickles, chopped
1/4 cup diced onion
8 slices American cheese (yes, the plastic-wrapped kind)

Directions

Preheat your oven to 350°F (175°C).
In a large skillet over medium heat, brown the ground beef with the onion and garlic until the meat is fully cooked. Drain the fat.
Stir in Worcestershire sauce, yellow mustard, salt, black pepper, garlic powder, and onion powder. Mix well.
In a large bowl, combine the torn hamburger buns with melted butter and sesame seeds. Toss to coat.
In a separate bowl, mix together mayonnaise, ketchup, sweet pickle relish, yellow mustard, white vinegar, sugar, paprika, garlic powder, and onion powder.
Start layering in a large casserole dish: first, spread half of the beef mixture, then half of the bun mixture, and half of the sauce. Add 1 cup of shredded cheddar cheese.
Repeat with the remaining beef mixture, bun mixture, and sauce. Top with the remaining cheddar cheese and the American cheese slices.
Cover the casserole with foil and bake for about 30 minutes. Remove foil and bake for an additional 15 minutes or until the cheese is bubbly.
Once baked, let it cool slightly before topping with shredded lettuce, dill pickles, and diced onion.

How to Serve Big Mac Casserole

Serve this delicious casserole warm, just like you would a pizza. Cut it into squares and top each square with extra lettuce, pickles, and diced onions for that authentic Big Mac feeling. Pair it with French fries or your favorite side for a complete meal.

How to Store Big Mac Casserole

If you have leftovers, store them in an airtight container in the fridge. It can last for about 3-4 days. You can also freeze it! Just wrap the cooled casserole tightly in foil or plastic wrap and it will last for about three months in the freezer.

Tips to Make Big Mac Casserole

For extra flavor, try adding chopped bacon or mushrooms to the beef mixture.
If you like a little heat, add some diced jalapeños to the topping.
Make sure to let the casserole cool for a few minutes before cutting; this makes it easier to serve.

Variation

You can switch up the types of cheese based on your preference. Try Swiss cheese or pepper jack for a different flavor. You can also change the toppings; add tomatoes or avocado for a fresh twist!
