Big Mac Casserole

What is Big Mac Casserole?

It is just as it sounds .. a Big Mac in casserole form to make a deliciously flavorful big mac casserole. All the flavors you love in a Big Mac loaded up into a single dish and on the table in under 30 minutes. I even added some potatoes in there to give you a side of fries. 

Can you use other meats besides beef?

Definitely! Use ground turkey, chicken, or even shredded chicken for this big mac casserole. Do know that if you swap the meat you will lose some of that big mac taste in the sense that a big mac burger is a beef patty. 

What size casserole dish should you use?

I am using a 8-inch by 8-inch dish but you can use any size for this big mac casserole. 

Tips for making this casserole

• Cut the potatoes into small pieces. The larger the pieces the longer they will take to cook.
• Use white onion, not yellow onion.
• The lettuce will get soggy in the fridge so I’d suggest adding it to each serving or to the top if you plan to eat it all. 
• Add a good amount of lettuce and have yourself a delicious and filling big mac casserole salad! 
• Using a higher percent fat beef will add some extra fatty flavor to this dish. If you end up with too much liquid after cooking, drain some but not all of it. 
• I  suggest you do not use low-fat cheese for this as it does not melt as well as full fat.

How to lower the fat per serving

If you need to lower the fat in each serving use low-fat mayonnaise and reduced-fat cheese. Reduced-fat cheese will not melt as well but will save some calories and grams of fat per serving in this big mac casserole. Alternatively using ground turkey 99/1 will lower it as well. 

Ingredients and Substitutes:

These are the main ingredients and substitutions. See the recipe card below for the full ingredients list and instructions for Big Mac Casserole.

Ground Beef: this recipe uses lean 96/4 ground beef. You can use any beef you’d like. The higher the fat the more flavor you’ll get. Substitute with ground turkey, chicken or shredded chicken. 

Mustard: what I consider to be the secret ingredient in the beef. I would not recommend omitting this. 

Russet Potatoes: you can substitute out the potatoes with sweet potatoes, golden potatoes or even fingerling. To try to add that French fry flavor I went with russet. Be sure to cut the potatoes into small pieces. The larger the pieces the longer it’ll take to cook. 

White Onion: to get that true Big Mac flavor be sure to use white onion, not yellow. 

Mayonnaise: I am using olive oil mayonnaise, you can use your favorite brand or a lower fat version. 

Ketchup: use regular, sugar free or vegetable ketchup. Whatever works best for you! Nutrition facts are for regular ketchup. 

Dill Pickles: for the true Big Mac taste use dill pickle chips. You will use chopped chips in the sauce along with juice and add full chips on top after baking. 

Cheddar Cheese: this recipe uses full fat cheddar cheese. You can use pre shredded or shred directly off a block. I would not suggest using low fat as it does not melt as well as full fat but that is entirely up to your preference. 

How to make this casserole:

Step 1

Preheat the oven to 375 degrees Fahrenheit. Wash and chop your potatoes, leaving the skin on, into small pieces. The smaller the better. 

Step 2

Heat a pan over medium and add the olive oil. Add potatoes to the hot oil and 1/4 cup of water. Season the potatoes generously with salt and pepper and cook until they begin to soften, stirring often so you do not burn the bottoms. This could take anywhere from 5 to 10 minutes depending on the size of your potatoes. Once the potatoes have softened place them in the baking dish. 

Step 3

In the same pan you cooked the potatoes add the ground beef and onions. Cook until the ground beef is mostly cooked through and the onions have softened. Season with salt, pepper, garlic powder, onion powder and mustard. Stir to combine well. Add the cooked beef mixture to the potatoes in the baking dish and mix together. 

Step 4

Top the potato and beef mixture with shredded cheddar cheese and cover with foil. Place in the oven for 15 minutes until the cheese has melted. 

Step 5

While the casserole bakes make you big mac sauce. Combine mayonnaise, ketchup, chopped pickles and pickle juice and stir to combine. Place in the fridge until ready to add to your casserole. 

Step 6

When the casserole is done baking, remove from the oven and remove the foil. Top with the big mac sauce drizzled across the top (use it all!), shredded lettuce, chopped white onion, chopped tomatoes and full pickle chips. Serve and enjoy your big mac casserole! 

What to serve with this recipe?

This big mac casserole is great as a standalone meal. You could also serve with fresh french fries, a side salad or roasted vegetables.
