Creamy Au Gratin Potatoes with a Secret Ingredient

My secret ingredient for homemade Au Gratin potatoes is a bit of Miracle Whip. It adds a bit of tang to the potatoes while keeping them creamy.

Jump to Recipe

Potatoes have always been a favorite of mine. In high school, when I got home from school, I would often make a package of instant mashed potatoes. Au Gratin potatoes are delicious, but we didn’t have them very often. Or, if we did, it was a boxed package. Now, don’t get me wrong, those are good, but not as good as homemade comfort food.

When I set out to make my own au gratin potatoes, I used my potato salad recipe as a starter. That’s one of the few things I use Miracle Whip in, and I like the tang it adds. I knew I wanted to do the same with these potatoes.

Oh, and they had to be cheesy (of course) with a creamy sauce. In other words, I wanted the perfect au gratin potato recipe. On the first try, I got really close to what I was looking for! After a bit of tweaking and remaking, I ended up with this amazing recipe.

Au Gratin potatoes are a perfect side dish to turkey at your next holiday table. It’s something different than regular mashed potatoes since this is a special meal.

Au Gratin Potatoes Ingredients

Miracle Whip

Miracle Whip adds a bit of a tang to recipes. I like the subtle added flavor it gives these potatoes over using mayonnaise. 

Salt and Pepper

Seasoning. Everything needs a little bit of seasoning. 

Cheddar Cheese

I prefer to use extra sharp cheddar cheese. Again, I like the strong flavor of it. But if you prefer, you can use mild cheddar cheese or any other kind of cheese you like with cheesy potatoes.

Russet Potatoes

While russet potatoes work well for this recipe, you can also make it with another kind of potatoes. I would also try with red potatoes, yukon golds, or other baking potatoes. The sliced potatoes are the main part of the dish, so make sure you choose good potatoes. Look for starchy potatoes as that helps to thicken the cheesy sauce while it bakes. 

Heavy Whipping Cream

The heavy cream is the base of the sauce in this recipe. You want a good, thick, delicious cream sauce for au gratin potatoes. If you don’t have heavy whipping cream, substitute with 1 1/2 cups of whole milk. You want to lower the amount a little bit so it doesn’t make the sauce too thin. 

Parmesan Cheese

The best cheese is the cheese you shred yourself. I highly suggest getting a block of parmesan cheese and shredding it fresh for this recipe. If you can’t get parmesan, you could substitute with gruyere cheese. 

Parsley

The parsley is just for a garnish at the end. You could also try it with fresh thyme if you prefer that flavor. 

Au Gratin Potatoes Recipe Add-Ins

As with any recipe you make yourself, there are always things you could add in to change the taste and customize it to your family’s preferences. Try any one of these great additions:

  • Add fresh garlic to the Miracle Whip mixture
  • Top with bread crumbs before baking for a crunchy topping on top of the potatoes
  • Mix diced yellow onion into the potatoes

Preparation

Preheat the oven to 350F. Coat a 9×13 baking dish with oil.

In a medium mixing bowl, whisk the miracle whip, salt, and pepper. Stir in the cheddar cheese.

Cut the potatoes into 1/8-inch thin slices. I found that my mandolin slicer was perfect for this. The slices were all the same size and it made the job quick and easy. Arrange half of the potato slices in the bottom of the baking dish in a single layer of potatoes.
