Ingredients You’ll Need

The ingredients for this Big Mac Casserole Recipe come together beautifully to mimic the burger’s layers, with hearty potatoes instead of buns, melted cheese to bind, and a tangy, creamy homemade sauce that seals the deal. Here are some notes to help you shop smart and prep effectively.

• Lean ground beef: I recommend 96/4 lean for a juicy but not greasy casserole.
• Russet potatoes: Keeping the skin on adds texture and nutrients; chop bite-sized for even cooking.
• White onion: Adds sweetness and depth; both chopped in the beef mixture and as a fresh topping.
• Olive oil: For sautéing potatoes and beef—helps with browning and flavor.
• Yellow mustard: This little punch really wakes up the beef and keeps things authentic.
• Garlic and onion powders: For extra seasoning without overpowering.
• Shredded cheddar cheese: Melts perfectly to bring the casserole together.
• Mayonnaise and ketchup: The base of your Big Mac sauce—totally homemade and fresher than store-bought.
• Chopped dill pickles and juice: Essential for that pickle zing you expect in a Big Mac.
• Fresh toppings: Vine tomato, shredded iceberg lettuce, more onion, and dill pickle chips add crunch and brightness.

Variations

I love experimenting with this Big Mac Casserole Recipe to suit different tastes and dietary needs. Feel free to play around with proteins or swap up the toppings to keep things fresh and exciting.

• Protein Swap: I’ve used ground turkey or chicken for a leaner version that’s just as tasty.
• Veggie Boost: Try adding diced bell peppers or mushrooms to the beef mixture for extra flavor and nutrients.
• Dairy-Free Option: Use dairy-free cheese or skip it altogether, and substitute mayo with avocado-based spread to keep it creamy.
• Spicier Kick: Add a little hot sauce to the Big Mac sauce or sprinkle chili flakes into the beef for your preferred heat level.

How to Make Big Mac Casserole Recipe

Step 1: Prepare and Soften the Potatoes

Start by preheating your oven to 375°F—this way, it’s all ready when you’re done prepping. Chop your russet potatoes into bite-sized pieces, leaving the skin on because that’s where loads of flavor and nutrients hide. Heat your olive oil on medium in a skillet, add the potatoes, and splash in 1/4 cup of water to help steam and soften them. Season generously with salt and pepper, then cook while stirring often to avoid burning. This step takes about 5 to 10 minutes, and you want your potatoes just tender but not falling apart. Once they soften, pop them into your baking dish and set aside.

Step 2: Cook the Beef and Onion Mixture

In the same skillet—no need for extra dishes—add your ground beef and chopped onions. Brown the beef until it’s almost cooked through and the onions soften. That’s when you add salt, pepper, garlic powder, onion powder, and yellow mustard, mixing everything well so the beef is rich and flavorful. Cooking the beef and onions together infuses those flavors beautifully. Once ready, stir this savory mixture into the potatoes already in your baking dish.

Step 3: Add Cheese and Bake

Sprinkle shredded cheddar cheese over your beef-and-potato mix, covering it evenly so every bite gets that cheesy goodness. Cover the dish tightly with foil to keep moisture in, then pop it in your preheated oven. Bake for about 15 minutes, enough time for the cheese to melt perfectly and the flavors to marry. I’ve found that keeping it covered ensures the casserole stays nice and moist without drying out.

Step 4: Whip Up the Big Mac Sauce

While your casserole bakes, mix mayo, ketchup, chopped dill pickles, and dill pickle juice in a small bowl to create that classic Big Mac sauce. Stir it well and pop it in the fridge until your casserole’s ready. This sauce is the magic touch that brings the whole dish alive, so don’t skip it!

Step 5: Garnish and Serve

When your casserole is out of the oven, take off the foil and drizzle the Big Mac sauce liberally all over the top—the more, the better! Finish it off with fresh shredded iceberg lettuce, chopped white onions, diced tomatoes, and dill pickle chips. These toppings add the fresh crunch and zing you expect when biting into a Big Mac. Serve immediately and watch everyone dig in happily.

Garnishes

I always top this casserole with extra shredded iceberg lettuce, chopped white onions, juicy diced tomatoes, and crunchy dill pickle chips because they replicate the classic burger toppings that make a Big Mac so irresistible. These fresh garnishes add texture, color, and that necessary bite that balances the rich, cheesy casserole below.

Side Dishes

To round out the meal, I like serving this with a crisp side salad or some steamed green beans to cut through the richness. Simple coleslaw or oven-baked fries also pair nicely, enhancing that diner-style experience without much fuss.

Creative Ways to Present

For special occasions, I like to serve this Big Mac Casserole Recipe in individual ramekins topped with little bowls of extra Big Mac sauce on the side for dipping. It looks festive and lets everyone customize their flavor intensity, which is always a hit at parties.

Make Ahead and Storage

Storing Leftovers

I usually let leftovers cool completely, then store them tightly covered in the fridge for up to 3 days. Keeping the toppings separate and adding them fresh when reheating helps maintain their crispness and flavor. It reheats beautifully without losing texture or moisture.

Freezing

If you want to freeze this casserole, I recommend skipping fresh toppings and sauce until you reheat it. Freeze the baked beef and potato mixture in an airtight container for up to 2 months. Thaw overnight in the fridge before reheating for best results.

Reheating

I gently reheat leftovers in a 350°F oven covered with foil to keep the moisture locked in, usually about 15-20 minutes until warmed through. Afterward, I add fresh toppings and drizzle the Big Mac sauce before serving to bring back that just-made magic.
