- 1/2 teaspoon black pepper: Delivers a subtle, zesty background heat.
- 1 tablespoon yellow mustard: Provides the iconic burger tang, sharpening up the beefy base.
- 1/4 cup ketchup: Brings slight sweetness and balances the savory notes in the casserole.
- 1/2 cup dill pickles (chopped): Essential for that classic Big Mac zing—don’t skip these!
- 1/2 cup mayonnaise: The creamy backbone for your signature special sauce.

- 4 cups frozen shredded hash browns (thawed): These make up the sturdy, golden base—just like the bun but way more fun!

- 1/2 cup mozzarella cheese: Adds gooey stretch and creamy richness to every scoop.

How to Make Big Mac Casserole Recipe
Step 1: Prep Your Oven and Skillet
Start by preheating your oven to 375°F (190°C) so it’s hot and ready for your casserole. Grab a large, deep skillet and place it over medium heat—this will be your playground for all those classic burger flavors.
Step 2: Brown the Beef and Onion
Add your ground beef and diced onion to the skillet. Let them sizzle together for about 6 to 8 minutes, stirring occasionally, until the meat is nicely browned and the onions have softened. Drain away any excess fat to keep your casserole from getting greasy.
Step 3: Build Flavor with Condiments and Cheese
Stir in the minced garlic, salt, black pepper, yellow mustard, ketchup, and those tangy chopped dill pickles. Throw in half of the shredded cheddar cheese too. Mix well—everything should be mingling together, looking (and smelling!) irresistible.
Step 4: Whip Up the Special Sauce
In a small bowl, whisk together the mayonnaise, relish, onion powder, and garlic powder. This “special sauce” is truly the soul of this Big Mac Casserole Recipe and lifts every bite to a new level of deliciousness!
Step 5: Combine and Layer
In a large mixing bowl, combine your thawed hash browns, the beef mixture from the skillet, and half of the special sauce. Give everything a gentle toss—this will form the main structure of your casserole.
Step 6: Assemble and Top
Spread the mixture evenly into a greased 9×13-inch baking dish, smoothing out the top. Sprinkle with the remaining cheddar cheese and all of the mozzarella. This melty cheese layer becomes the irresistible crust everyone fights over.
Step 7: Bake and Finish
Pop your casserole in the oven—no cover needed. Bake for 25 to 30 minutes, until it’s bubbling and golden on top. Let it cool slightly, then top generously with shredded lettuce, a swirl of the leftover special sauce, and for the full experience, a sprinkle of sesame seeds.
How to Serve Big Mac Casserole Recipe

Garnishes
For that signature Big Mac look and crunch, always finish your casserole with a mound of cool, shredded lettuce and a final drizzle of extra special sauce. If you’re feeling playful, a handful of sesame seeds sprinkled right before serving makes the casserole look strikingly like a giant deconstructed burger—it’s both fun and delicious!
Side Dishes
Craving the true spirit of a burger night? Serve your Big Mac Casserole Recipe with crispy baked fries or sweet potato wedges. Prefer something lighter? A tangy coleslaw or a simple cucumber salad brings delicious brightness to the richness of the dish, balancing out each bite.
Creative Ways to Present
This casserole loves a little showmanship. Try spooning it into warm, toasted slider buns for a playful party appetizer or serving it in individual ramekins for a personalized meal. For a fun “burger bar,” let guests top their servings with extra pickles, onions, or jalapeños—the possibilities are as big as your imagination!
Make Ahead and Storage
Storing Leftovers
This casserole keeps wonderfully in the fridge. Simply cover the dish tightly or transfer leftovers to an airtight container. They’ll stay fresh for up to three days, making weekday lunches or quick dinners a breeze.
Freezing
If you want to make your Big Mac Casserole Recipe ahead, it freezes beautifully before or after baking. Wrap the assembled (but unbaked) casserole tightly in foil and plastic wrap for up to two months. Thaw overnight in the fridge before baking as usual. For leftovers, just freeze portions individually and thaw as needed.
Reheating
To reheat, simply pop a portion in the microwave for a couple of minutes, or cover the whole baking dish with foil and warm in a 350°F oven until hot throughout. Add the fresh lettuce and sauce just before serving to keep every bite as vibrant as the first time.
FAQs
Can I make this Big Mac Casserole Recipe low-carb?
Absolutely! Swap the hash browns for cooked cauliflower rice to cut down the carbs while still enjoying that irresistible Big Mac flavor. You’ll be pleasantly surprised at how well the swap works.
Is it possible to make this recipe ahead of time?
Yes! You can assemble the casserole a day in advance, cover it well, and stash it in the fridge. When you’re ready to eat, just bake as directed, then add the lettuce and sauce right before serving.
Can I use a different type Main Course
Go for it! While cheddar and mozzarella give the best mix of flavor and meltiness, feel free to try Monterey Jack, Colby, or even American cheese for an extra burger-like experience.
What kind of pickles should I use?
Dill pickles are classic for the authentic taste, but bread-and-butter pickles will lend a sweeter, more tangy kick if you’re in the mood for a twist. Chop them finely for that signature texture throughout.
Does this recipe work with ground turkey or chicken?
Definitely! If you’re looking for a lighter option, ground turkey or chicken can easily be swapped in. Just be sure to season well and perhaps add a splash of Worcestershire sauce for extra savory oomph.
