Ingredients You’ll Need

Every ingredient in this Big Mac Casserole Recipe plays a role in capturing the spirit of that famous burger. From the russet potatoes standing in for the bun texture to the special sauce mix, these components work together beautifully.

• Lean ground beef: I recommend 96/4 lean for savory flavor with less grease, which keeps the casserole balanced.
• Russet potatoes: Leaving the skin on adds rustic texture and nutrients, plus they crisp up nicely.
• White onion: Adds sweetness and aromatics, key for that Big Mac vibe.
• Olive oil: Just enough to soften the potatoes and prevent sticking.
• Yellow mustard: It’s an unsung hero here, cutting through the richness with tang.
• Cheddar cheese: Sharp cheddar melts perfectly to top everything with gooey goodness.
• Mayonnaise and ketchup: Base of the Big Mac sauce, delivering creaminess and sweetness.
• Dill pickles and juice: For that signature pickle punch in the sauce and as a topping.
• Vine tomato, shredded iceberg lettuce, and pickle chips: Fresh toppings to finish the dish just like your favorite burger.

Variations

One of the best things about this Big Mac Casserole Recipe is how you can tweak it to suit whatever you have on hand or your personal preferences. I love making it with a few variations depending on the season or mood.

• Swap the beef: Sometimes I use ground turkey or chicken for a lighter version that still satisfies.
• Dairy-free sauce: Use vegan mayo and skip the cheese to make it dairy-free without losing big taste.
• Extra veggies: Add sautéed mushrooms or bell peppers to boost nutrition and flavor layers.
• Spicy kick: Stir in a little hot sauce or chili powder if you want that extra zing.

How to Make Big Mac Casserole Recipe

Step 1: Preheat Oven and Prep Potatoes

Start by preheating your oven to 375°F — it needs to be ready when your casserole comes together. Wash your russet potatoes and chop them into small, bite-sized pieces, skin on. The smaller the pieces, the faster and more evenly they’ll cook, which I always appreciate when time’s tight.

Step 2: Cook Potatoes on the Stovetop

Heat a pan on medium and add the olive oil. Toss in your chopped potatoes along with 1/4 cup of water—this helps steam them a bit, softening them quickly. Season generously with salt and pepper. Stir often to keep them from sticking or burning, cooking until just tender but not mushy, about 5 to 10 minutes depending on chunk size. Once they’re starting to soften, transfer them to your baking dish.

Step 3: Brown the Beef and Onion

Using the same pan (waste not, want not), add your ground beef and chopped onion. Let these cook together until the beef is mostly browned and the onion is softened, stirring often. Season with salt, pepper, garlic powder, onion powder, and the mustard—these last ingredients bring that Big Mac zest to the meat. Mix it well, then combine the beef mixture with your potatoes in the baking dish, ensuring everything is evenly distributed.

Step 4: Add Cheese and Bake

Sprinkle the shredded cheddar cheese over the top of your potato and beef mix. Cover the dish tightly with foil to keep moisture in and pop it into the preheated oven. Bake for 15 minutes, just enough for that cheese to melt perfectly and everything to meld together.

Step 5: Whip Up the Big Mac Sauce

While the casserole is in the oven, mix together your Big Mac sauce ingredients: mayonnaise, ketchup, chopped dill pickles, and pickle juice. Give it a good stir, then set it in the fridge to chill until you’re ready to plate. I love how this sauce amps up the whole dish with its creamy tang and pickle punch.

Step 6: Finish with Toppings and Serve

When the casserole is ready, take off the foil and evenly drizzle the Big Mac sauce over the top. Then pile on shredded iceberg lettuce, chopped white onions, diced vine tomato, and dill pickle chips for that iconic finishing touch. Serve it straight away—trust me, it tastes best fresh and warm!

How to Serve Big Mac Casserole Recipe

Garnishes

I love finishing this casserole with fresh, crunchy iceberg lettuce and crisp white onions – they bring brightness and texture that really volley off the rich beef and melty cheese. Adding those dill pickle chips on top is non-negotiable in my book because they deliver that tangy snap that screams “Big Mac.” Chopped vine tomatoes give a juicy burst, rounding out the flavors beautifully.

Side Dishes

Simple sides work best here: a crisp green salad or steamed veggies keep the meal balanced. Sometimes I serve it with oven-baked fries or sweet potato fries for a more indulgent feel. If you want to keep it light, steamed green beans or a cabbage slaw complement the casserole’s richness.

Creative Ways to Present

For special occasions, I’ve served this Big Mac Casserole Recipe in individual ramekins topped with tiny layers of shredded lettuce and a pickle slice for a fun “deconstructed” effect. You can also layer it in a clear casserole dish so guests can admire those layers before digging in. It makes the meal feel a little fancy, while still being totally comforting.

Make Ahead and Storage

Storing Leftovers

Leftover Big Mac Casserole stores well in an airtight container in the fridge for up to 3 days. I like to remove any fresh toppings first (lettuce and tomatoes can get soggy) and add those fresh when reheating. Potatoes and beef taste great cold too if you’re into that, but warmed up is always best.

Freezing

I’ve frozen this casserole successfully, but for best texture, I recommend freezing before adding fresh toppings. Wrap it tightly and freeze for up to 2 months. When thawed overnight in the fridge, the flavors meld even more!

Reheating

To reheat, I cover the casserole with foil and warm it in a 350°F oven until heated through (about 20 minutes). This helps keep the potatoes moist and cheese melty without drying out. Fresh toppings go on afterwards so they stay crisp.
