Why This Cheesy Au Gratin Potatoes Recipe is the Best

First of all, it’s easy to make and so much better than boxed au gratin potatoes. These potatoes are totally delicious and creamy with a hint of garlic and a tangy cheese topping.

Thinly cut potatoes are cooked with garlic in a skillet, covered with creamy sauce and cheese, then baked to perfection. The result is a creamy, cheesy scalloped potatoes au gratin dish.

While the potatoes are baking in the oven, you are free to get the rest of your meal prepared.

Or, if you put this in the oven along with a chicken, both will be ready at about the same time. I love to put a couple of items in the oven at once – it’s carefree cooking.

This dish looks so cheesy and wonderful, you’ll get hungry just thinking about it!

This dish will always come back empty. Hands down, these are the potatoes for the holidays, Mother’s day brunch, or Easter dinner.

This truly is the best recipe for homemade au gratin potatoes with cheese for the beginner or expert cook.

What are the best potatoes for au gratin?

For this au gratin potatoes recipe, I recommend using Yukon gold potatoes, which you can find in every grocery store. If you want to try another kind of potato, my second choice would be Russet potatoes.

I do not recommend making this dish with red potatoes because they aren’t starchy enough for this dish. Although, we can do all sorts of delicious things with red potatoes.

Ingredient Substitutions

You could use another type of starchy potato instead of Yukon Gold.

You could also swap the type of cheese. Swiss is perfect for making Swiss cheese au gratin potatoes.

Other Cooking Methods

Air Fryer Potato Gratin

Since this dish is first prepared in a skillet, there’s an additional step to convert it from oven-baked to air-fried.

You’ll need to transfer the cooked potatoes and cheese sauce from the skillet to a dish that fits in your air fryer basket.

Top with cheese and place the dish in your air fryer oven. Bake at 350 degrees for about 20 minutes.

Cooking Tips for This Easy Potato Gratin Recipe

Use Yukon gold or Russet potatoes for this au gratin potatoes recipe with heavy cream. Yukon Gold potatoes are my personal choice for this recipe for au gratin potatoes because they have lots of starch, which helps the casserole hold together well.

Cut the potatoes into slices about 1/8 to 1/4-inch thick. You don’t want them any thicker, and slicing them any thinner will cause the potatoes to cook too quickly and then break apart in your dish.

Heavy cream gives these potatoes a lovely richness. Heavy cream has multiple names – heavy cream, whipping cream, double cream.

Do not substitute whole milk. Using half-and-half is not best for this potatoes gratin recipe either. One big plus when cooking with heavy cream is the dish will reheat better. I often consider how the food will turn out the second time around. 

Use Jarlsburg cheese. If you don’t have Jarlsburg or it’s not available at your grocery store, you can use Swiss or even Cheddar.

Grate the cheese yourself. Cheese that comes already grated contains an anti-caking agent to keep it separated in the package. Pre-grated cheese doesn’t melt as well and can cause the sauce to have a grainy texture.

Recipe Variations

This is a basic potato dish, but you can change it up very easily and make it your own. Here are some suggestions for what to add to au gratin potatoes:

  • Add some ham or cooked bacon.
  • Use a different cheese such as Cheddar, Colby, or Parmesan.
  • Sprinkle on sliced green onions, chives, or fresh herbs just before serving. Parsley or tarragon works wonderfully.
  • Add some greens. Fresh kale or baby spinach would be delicious. 
  • Stir in 1/4 cup of basil pesto for an extra tasty twist. 
  • Use half sweet potatoes for a winning sweet/savory combo.

What is the difference between au gratin and scalloped potatoes?

The main difference between these two popular potato dishes is cheese!

Scalloped potatoes consist of thinly sliced potatoes layered in a casserole dish and baked with a creamy milk sauce.

Potatoes au gratin, on the other hand, has grated cheese between the layers, making this dish way cheesier throughout.

Can you make au gratin potatoes ahead of time?

This potato casserole is best served straight out of the oven, but you can make this easy recipe for au gratin potatoes up to two days ahead of time.

Pop it in the fridge. When you are ready to serve it, bake it at 350 degrees until heated through.

Use a stainless steel skillet and not a cast-iron skillet. Cast iron is great for cooking but not to be used for storing food. You want to keep cast iron dry to preserve the skillet’s seasoning and prevent rust.

How to Store Au Gratin Potatoes

Place any leftover au gratin potatoes in an airtight container in the refrigerator. This potato side dish will keep in the fridge for up to five days.

Can you freeze au gratin potatoes?

Yes, you can. Store them in a freezer-safe airtight container and place it in your freezer. They will keep in your freezer for up to three months.

Note: When you freeze these au gratin potatoes, you may get some changes to texture and flavor. Also, beyond two weeks, the quality of your potato dish might deteriorate.

How to Reheat Au Gratin Potatoes

Before reheating frozen au gratin potatoes, allow the dish to thaw thoroughly. Once defrosted, there are three ways to reheat this dish:

Oven: Place your defrosted potatoes au gratin in an oven-safe dish that has a lid (or cover with foil). Bake it in the center of a preheated 350-degree oven for 25 to 30 minutes. Remove the lid or foil and bake for another 5 minutes to brown and crisp the top.

Stove Top: Transfer your thawed potatoes to a cooking pot with a lid. Cook over low to medium heat with the lid on for about 20 minutes.

Microwave: Place your defrosted au gratin potatoes in a microwave-safe container and cover with wax paper or microwave-suitable plastic wrap, leaving a small portion open for air to pass through. Heat on high for 3 minutes and let it rest for 30 seconds. Then heat for another 3 minutes. Repeat if necessary.

Reheating Note: Whichever reheating method you use, use a food thermometer to ensure that your potato dish has reached an internal temperature of 165 degrees Fahrenheit. This is the recommended temperature to ensure that your food can be eaten safely.
