How to Make Big Mac Casserole Recipe

Step 1: Prepare the Base

Start by preheating your oven to 400 degrees Fahrenheit so it’s ready for baking. Then, heat olive oil in a large skillet over medium heat and add your lean ground beef. Break it up carefully with a spatula or a wooden spoon, cooking until it browns nicely for about 3 to 4 minutes. This step builds a savory foundation that you’ll love.

Step 2: Add the Veggies and Spices

Once your beef starts cooking, toss in the diced bell peppers, sweet onions, garlic, and those diced gold potatoes. Sprinkle in the garlic powder, onion powder, paprika, salt, black pepper, and the first bit of Dijon mustard. Stir everything together, then cover the skillet and let it cook for about 10 minutes. This ensures the potatoes soften and all the flavors marry beautifully.

Step 3: Brown and Finish the Filling

Remove the cover and give the mixture a good stir, letting it cook uncovered for another 10 minutes. This helps the potatoes take on a slight golden-brown color and adds a touch of crispness. Once the potatoes are tender and starting to brown, turn off the heat and stir in one cup of shredded cheddar. This gooey, cheesy mixture is the heart of your Big Mac Casserole Recipe.

Step 4: Bake to Perfection

Transfer your savory meat and veggie mixture into a 9×9-inch baking dish lightly sprayed with oil—or if your skillet is oven safe, you can use that directly. Top the casserole with the remaining half cup of cheddar cheese. Pop it into the oven and bake for 10 minutes until that cheese melts into a bubbly, golden blanket. Allow it to cool just slightly before moving on.

Step 5: Make the Signature Burger Sauce

While the casserole is baking, whisk together your creamy sauce. Combine Greek yogurt, mayonnaise, ketchup, Dijon mustard, garlic powder, paprika, honey, apple cider vinegar, and a pinch of salt and black pepper. This sauce is where that unmistakable Big Mac flavor comes to life, adding a luscious tang and richness to your casserole.

Step 6: Add Toppings and Serve

Let the casserole cool for about 10 minutes after it’s out of the oven. Then, pile on those classic Big Mac toppings — shredded lettuce, diced sweet onions, dill pickles or chips, diced tomatoes, and extra cheddar if you like a cheesier bite. Finally, drizzle generously with your homemade burger sauce. For the ultimate taste experience, add toppings right before serving to keep everything fresh and crisp.

Garnishes

Freshness is everything, so the crisp shredded lettuce, tangy pickles, and juicy diced tomatoes are more than just garnishes — they balance the richness of the casserole perfectly. A sprinkle of extra shredded cheddar cheese on top can bring even more gooey, cheesy goodness.

Side Dishes

This casserole is a meal on its own, but if you want to round it out, consider a light green salad or some crunchy carrot sticks on the side. Simple sides keep the focus on the rich, layered flavors of the Big Mac Casserole Recipe without overwhelming your palate.

Creative Ways to Present

Try serving individual portions with a crispy baked potato skin or inside hollowed-out bell peppers for a fun twist. You can also turn leftovers into loaded baked potato toppings or even stuff them inside warm pita pockets for an on-the-go Big Mac feast that’s anything but ordinary.

Make Ahead and Storage

Storing Leftovers

Once cooled completely, store your Big Mac Casserole in an airtight container in the refrigerator for up to 3 days. Reheating gently helps maintain the textures and that delicious burger sauce flavor.

Freezing

You can freeze the casserole, too! Wrap it tightly with foil and plastic wrap or place it in a freezer-safe container, where it will stay good for up to 2 months. Thaw overnight in the fridge before reheating for the best results.

Reheating

Reheat individual portions in the microwave or warm the entire casserole in a 350 degrees Fahrenheit oven until heated through and bubbly again. Add fresh toppings and sauce after reheating to keep that delightful crunch and tang.

FAQs

Can I use ground turkey or chicken instead of ground beef?

Absolutely! Ground turkey or chicken works great in this Big Mac Casserole Recipe. They offer a lighter alternative while still soaking up all the wonderful flavors from the seasonings and sauces.

Is this casserole spicy?

Not at all. The spices used, such as paprika and garlic powder, add warmth and depth without heat, making the dish friendly for all taste preferences.

Can I make the burger sauce ahead of time?

Yes! The sauce actually tastes better after the flavors meld for a few hours in the fridge. Just store it in a sealed container and give it a quick stir before using.

Can this recipe be doubled for a larger crowd?

Definitely. Simply double the ingredients and use a larger baking dish or two dishes. Just adjust the baking time slightly, checking for melted cheese and bubbly edges.

What’s the best type of potato to use?

Gold potatoes are perfect because they hold their shape well but become tender and slightly crispy, which adds fantastic texture to the casserole.
