FAQs for Big Mac Casserole
For this Big Mac Casserole recipe, you should use a 9×13 inch casserole dish. This size will provide ample space for all the ingredients to layer evenly and cook properly.
Big Mac sauce, inspired by McDonald’s, is allegedly made from mayonnaise, sweet pickle relish, yellow mustard, vinegar, garlic powder, onion powder, and paprika, but the exact amounts of each ingredient are unknown. This recipe uses French dressing and a bit of ketchup to get the spot on flavor without the guess work.
Big Mac Sauce has a distinct, tangy flavor with a slightly sweet undertone similar to Thousand Island Dressing. It’s creamy and rich, thanks to the mayonnaise base, with the tanginess largely coming from the pickle relish and vinegar. The blend of spices gives it a savory depth and a hint of smokiness.
A traditional Big Mac from McDonald’s consists of two beef patties, American cheese, iceberg lettuce, pickles, minced onions, and the iconic Big Mac Sauce, all sandwiched between a three-part sesame seed bun. The middle bun, known as the “club” layer, is an additional layer of bread placed between the two beef patties.

Key Ingredients
- Ground Beef: An 85/15 blend of ground beef is good for baked dishes because it stays moist thanks to the bit of fat. It doesn’t have as much fat as 80/20 beef so you don’t need to drain the meat. If you do use a higher fat beef, drain the meat so your filling isn’t greasy.
- Big Mac Sauce: This signature sauce, inspired by McDonald’s, provides the distinctive “Big Mac” flavor. It’s similar to a Thousand Island dressing but a bit more vinegary and sweet. There is a spot-on copycat recipe for this delicious secret sauce in this post, past the Variations section.
- Seasonings: Cooking the onions in the beef give it a savory, slightly sweet, aromatic flavor. The seasoning blend of garlic powder, salt, and black pepper give the beefy mixture that hamburger taste without overpowering or competing with the special sauce.
- American Cheese: Chopped American cheese adds a creamy, slightly tangy, goodness to the beefy filling. American cheese melts really well so it gives a smooth texture to the meaty casserole filling.
- Cheddar Cheese: Shredded cheddar cheese provides a sharp, tangy flavor that contrasts nicely with the milder American cheese. It also melts beautifully, giving it a gooey, melty top layer.
- Tater Tots: These potato bites offer a crispy, golden exterior and soft interior, and make the perfect topping for easy casserole dishes. You don’t want to defrost them beforehand or they will overcook and they won’t have the right texture.
- Toppings: It wouldn’t be a Big Mac dish without some classic Big Mac toppings. You definitely want fresh crisp lettuce and juicy diced tomatoes to break up the savory, rich burger and fries flavors of this heavy casserole. And of course, some extra melty American cheese never hurt anyone!
Can you make Big Mac Casserole ahead of time?
Yes, Big Mac Casserole is a great dinner to make ahead of time! You can either double the recipe by using the slider tool in the recipe card and freeze one pan for later, or divide the original recipe into two smaller foil pans. An 8 × 8 pan of Big Mac Casserole will feed about 4-5 people. Prepare the filling and layer the casserole as usual. Wrap the pan tightly with plastic wrap, then foil, before freezing up to 3 months. It can be baked from frozen. Remove plastic wrap and foil before baking from frozen for about an hour.
Variations
- Bacon: Bacon makes everything better! Add 6-8 slices cooked, crumbled bacon to the cooked beef mixture or mix in 2-3 tablespoons bacon bits.
- Meat: Use any ground meat instead of ground beef like ground turkey, ground sausage, or ground chicken. If using a leaner ground meat, add a tablespoon oil to the skillet when browning.
- Big Mac Sauce: The copycat Big Mac Sauce is where it’s at but you can use Thousand Island in a pinch. Add a tablespoon of sweet pickle relish and an extra bit of ketchup to get the dressing closer to the special sauce flavor.
- Potatoes: You can swap the frozen tots for frozen french fries, sweet potato puffs, shredded hash browns, or diced potatoes. If you use thawed potatoes, just reduce the cooking time by 15-20 minutes.
