1. Cook the beef mixture. In a skillet, cook the onions until softened. Add the garlic, then ground beef seasoned with salt, pepper, garlic powder, and onion powder. Cook until browned.
2. Transfer to a baking dish. Move the beef mixture to a 9×13-inch baking dish. Mix in the Thousand Island dressing, diced pickles, and shredded cheese.

6. Serve hot. Enjoy your Big Mac casserole!
Tips For the Best Big Mac Casserole
Follow these tricks for the very best dish.
- Go lean. Lean ground beef (96/4) prevents the casserole from becoming overly greasy.
- Pick your potatoes. You can use various types of potatoes such as French fries, cubes, or even fresh potatoes.
- Pickle prep perfection. Chop the pickles into small pieces instead of slicing them so you get some in every bite.
- Get a step ahead. You can brown the beef mixture up to 2 days ahead of time. Then assemble with the tots and bake when ready.
- Make it extra crispy. After baking, broil the casserole for a few minutes to get the tots extra crispy and golden brown.
- Drain carefully. Drain excess grease after browning the beef, but leave a couple of tablespoons for flavor.
- Have fun! Customize your casserole with add-ins like bacon, diced red onions, or your favorite burger toppings. Or, make it low-carb by using it as a salad topper instead of adding potatoes.
