I first tried this casserole on a busy weeknight, and it instantly became a favorite because it’s quick to throw together and hits all those crave-worthy notes from a Big Mac.

What makes this Big Mac Casserole Recipe truly special is how it layers the components — the savory beef, tender potatoes, tangy sauce, and fresh toppings all come together in perfect harmony.

Plus, it’s easy to customize, so you can tweak it to suit your taste or what you have on hand.

Ingredients You’ll Need

Each ingredient in this Big Mac Casserole Recipe plays a crucial role, from the lean ground beef providing that classic burger base to the russet potatoes adding comforting texture. I like to keep the potato skins on because they add flavor and nutrients, plus they hold together nicely when baked.

• Lean ground beef: Choose 96/4 for less fat but plenty of flavor so the dish isn’t greasy.
• Russet potatoes: Their starchiness creates a hearty base that soaks up all the meaty goodness.
• White onion: Adds sharp, sweet notes that balance the richness of the beef.
• Olive oil: Helps cook the potatoes to a tender, golden finish without sticking.
• Yellow mustard: A little tang that’s subtle but essential to mimicking Big Mac’s signature flavor.
• Garlic powder and onion powder: These seasonings deepen the savory notes effortlessly.
• Cheddar cheese: Sharp and melty — the crowning touch of classic comfort.
• Mayonnaise and ketchup: The base for the homemade Big Mac sauce, rich and creamy with a bit of sweetness.
• Dill pickles and pickle juice: These bring the all-important tang and crunch that make a Big Mac so memorable.
• Vine tomato, shredded iceberg lettuce, additional white onion, and dill pickle chips: Fresh, crisp toppings to finish off with that classic burger bite.

Variations

One of the things I love about the Big Mac Casserole Recipe is how easy it is to make your own tweaks. You can swap out ground beef for turkey or chicken for a lighter option, or even try it vegetarian by using textured vegetable protein or mushrooms. It’s all about making it work for your tastes and what you have on hand.

• Turkey or Chicken: I’ve made this with ground turkey a few times, and it gives a lighter flavor that still soaks up all the seasoning beautifully.
• Vegetarian: Using sautéed mushrooms or a plant-based ground substitute works great if you want to skip meat.
• Extra Cheese: My family loves it with an extra layer of cheese on top; it gets golden and bubbly when baked.
• Spicy Kick: Add a pinch of cayenne or some chopped jalapeños to the beef mixture to give it some heat.

How to Make Big Mac Casserole Recipe

Step 1: Preheat Your Oven and Prep the Potatoes

Start by preheating your oven to 375°F (190°C). Wash and chop your russet potatoes into small, bite-sized chunks—leaving the skins on is a personal favorite because it keeps them sturdy. The smaller the pieces, the faster they cook, so aim for about 1-inch cubes. This helps the potatoes soften evenly in the pan before baking.

Step 2: Cook the Potatoes to Tenderness

Heat a pan over medium heat and add the olive oil. Toss in your chopped potatoes along with 1/4 cup of water — this bit of water creates steam and helps soften the potatoes without drying them out. Season well with salt and pepper. Stir often to avoid sticking or burning. This takes about 5 to 10 minutes until the potatoes are just starting to get tender but not fully cooked. Transfer them into your baking dish once ready.

Step 3: Cook the Beef and Onions Together

In the same pan, add the ground beef and chopped white onion to save on cleanup and build flavor. Cook until the beef is nearly done and the onions are soft—breaking the beef into crumbles as it cooks. Season the mixture with garlic powder, onion powder, salt, pepper, and yellow mustard. Stir everything so the flavors meld perfectly, then fold the beef and onion mix right into the potatoes in your baking dish.

Step 4: Add Cheese and Bake

Sprinkle the shredded cheddar cheese evenly over the top of your beef and potato mixture. Cover the dish with foil to help the cheese melt without drying out the casserole. Pop it into your preheated oven for about 15 minutes until the cheese is bubbling and nicely melted.

Step 5: Prep Your Big Mac Sauce

While your casserole bakes, combine mayonnaise, ketchup, chopped dill pickles, and pickle juice in a small bowl. Mix well until smooth and tangy. I always refrigerate this sauce until I’m ready to add it to keep it fresh and thick for drizzling.

Step 6: Top and Serve

When your casserole comes out of the oven, remove the foil and drizzle the Big Mac sauce evenly over the top. Then add your fresh toppings: shredded iceberg lettuce, chopped white onions, chopped vine tomatoes, and dill pickle chips. Serve it immediately and watch how quickly it disappears!

How to Serve Big Mac Casserole Recipe

Garnishes

I really enjoy topping my Big Mac Casserole with crisp iceberg lettuce and extra dill pickle chips — they bring that crunchy freshness similar to the burger experience. I also like to sprinkle a few extra chopped white onions over the top for a mild bite and a pop of color. For a little extra flair, adding thin slices of tomato helps keep it bright and fresh tasting.

Side Dishes

This casserole pairs wonderfully with crispy oven-baked fries or a simple green salad dressed with something light and tangy like a lemon vinaigrette. I love serving it alongside coleslaw to add some crunch and balance the richness of the casserole.

Creative Ways to Present

For a fun party twist, you can portion out the Big Mac Casserole into small ramekins or mini cast iron skillets — they make such cute individual servings! I’ve also layered this casserole into a clear glass dish to show off the layers of potatoes, beef, cheese, and toppings for a pretty presentation when serving guests.

Make Ahead and Storage

Storing Leftovers

I store leftovers in an airtight container in the fridge and find that the casserole holds up nicely for up to 3 days. Just make sure to keep the fresh toppings and sauce separate if possible, adding them freshly when reheating.

Freezing

Freezing is totally doable! I freeze the casserole without the fresh toppings or sauce to keep texture intact. Wrap it tightly with foil and plastic wrap, and it should keep well for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers in the oven at 350°F (175°C) for about 15 minutes to bring back the cheesy melted goodness. Avoid microwaving if you want to keep the texture crispier, but it works fine for a quick reheat. Add fresh toppings and sauce after reheating to keep them fresh.
