Potatoes: Small diced potatoes make the casserole satisfying while keeping the cheeseburger flavor front and center.

Cheddar cheese: Sharp cheddar provides the classic cheesy burger flavor.

Dill pickles: Add the signature tangy crunch.

Mayonnaise, ketchup, and mustard: Create a simple homemade burger sauce.

How to Make Big Mac Casserole

1. Prepare the potatoes

Preheat your oven to 375°F (190°C).

Dice the potatoes into small, even pieces. Boil them in lightly salted water for approximately 8–10 minutes, until just fork-tender.

Drain thoroughly and set aside.

2. Brown the ground beef

Heat olive oil in a large skillet over medium heat.

Add the diced onion and cook for 3–4 minutes. Add the ground beef and cook until browned, breaking it into small pieces.

Stir in the minced garlic, paprika, salt, and black pepper. Cook for another minute.

Drain excess grease if necessary.

3. Prepare the homemade burger sauce

In a medium bowl, whisk together mayonnaise, ketchup, yellow mustard, milk, and finely chopped dill pickles.

The sauce should be creamy and easy to stir into the beef mixture.

4. Combine the casserole filling

Add the cooked potatoes to the skillet with the seasoned beef.

Pour in the burger sauce and gently mix until everything is evenly coated.

Stir in half of the shredded cheddar.

5. Assemble and bake

Lightly grease a 9×13-inch baking dish.

Transfer the beef and potato mixture into the dish and spread evenly.

Sprinkle the remaining cheddar over the surface.

Cover loosely with foil and bake for 15 minutes. Remove the foil and bake for another 10–15 minutes, until the cheese is melted and the center is thoroughly heated.

6. Add the cheeseburger toppings

Let the casserole rest for approximately 5 minutes.

Finish with shredded lettuce, extra diced pickles, sesame seeds, and a light drizzle of additional burger sauce, if desired.

Serve immediately.

Tips for the Best Results

Pre-cook the potatoes. Raw potatoes may not become tender during the relatively short baking time.

Drain excess beef fat. This prevents the casserole from becoming greasy.

Use freshly shredded cheddar. It melts smoothly and creates a delicious topping.

Add lettuce after baking. Baking lettuce would make it wilt and lose its fresh texture.

Adjust the pickles to taste. Start with the suggested quantity and add more when serving.

Easy Variations

Big Mac Casserole Without Potatoes

Omit the potatoes and replace them with lightly cooked, well-drained cauliflower florets. The result will have a different texture but retain the burger-inspired flavors.

Extra Cheesy Version

Add another ½ cup of cheddar to the topping.

Spicy Cheeseburger Casserole

Mix a small amount of hot sauce into the homemade burger sauce or add diced jalapeños before baking.

Big Mac Casserole with Rice

Replace the potatoes with approximately 3 cups of fully cooked rice. Avoid adding uncooked rice because the recipe does not contain enough liquid to cook it properly.

What to Serve With Big Mac Casserole

This casserole is already filling, so fresh and simple sides work particularly well.

Try sliced cucumbers, a green salad, steamed green beans, or roasted vegetables.
