Potatoes au gratin is a popular dish during the holidays but needs precious oven space and an hour and a half to bake. If you want to enjoy these rich, cheesy potatoes but don't have much time, this microwave recipe is the answer. You can even use the food processor to slice the potatoes to save more time for these quick scalloped potatoes.

This simplified recipe calls for just four ingredients—Yukon Gold potatoes, cream of mushroom soup, milk, and cheddar cheese—and just 20 minutes to cook. It's perfect for any holiday table but quick and easy enough for a weeknight meal.

What's the difference between potatoes au gratin and scalloped potatoes?

Although very similar, there is one ingredient that distinguishes these two creamy potato baked dishes from each other: cheese. While scalloped potatoes are made with cream, au gratin potatoes also include cheese, which can be layered in or just sprinkled on top.

Tips

  • Make sure to slice the potatoes thinly, or they won't cook quickly enough.
  • Microwaves cook differently from each other and tend to cook unevenly. Check the doneness of the potatoes at regular intervals and stir the mixture if necessary to redistribute.
  • Yukon Gold potatoes are called for in this recipe because of their creamy texture and buttery taste. If you would like to use a different potato variety, choose russet or red-skinned.

Recipe Variations

  • If you'd rather not use canned cream of soup, you can make a homemade version using butter, flour, chicken broth, and milk. (If you'd like to keep the recipe vegetarian, simply replace the chicken broth with vegetable broth or more milk.)
  • Feel free to change up the type of cheese, or use a combination of cheeses. Gruyère or Swiss are great choices, and Parmesan along with the cheddar is a nice blend of flavors.
  • A bit of fresh or dried herb will add a welcome earthiness to the recipe. Try thyme, sage, or rosemary.
  • For a more filling dish, add some cooked bacon or ham to the casserole.
