Creamy gluten-free scalloped potatoes make an elegant side dish that's perfect for special occasions and holiday menus. It's also an easy, layered, and hearty dish that will feed a crowd but won't break the bank. 

Sweet rice flour has a higher starch content than regular rice flour, which makes it an excellent thickening agent and ideal for a gluten-free casserole. Don't let the word sweet fool you, though. This flour isn't sweet, but instead works beautifully to help give this scalloped potato dish its creamy essence. It works well as a thickener for other sauces, too, such as gluten-free béchamel. 

This dish is sure to be a crowd-pleaser at your next gathering. It's a side dish that everyone can enjoy— not just for those who are following a gluten-free diet.

  • 1/4 cup unsalted butter, or dairy-free butter substitute, diced
  • 1/2 cup coarsely grated cheddar cheese, packed
  • 1/4 teaspoon smoked paprika, optional
  • 3 tablespoons sweet rice flour

How to Store and Freeze Gluten-Free Scalloped Potatoes

This recipe will keep refrigerated and covered for up to 5 days. Reheat in the oven at a low temperature, covered loosely with a little bit of foil.

You can also freeze this casserole, in part or in whole, in a well-sealed container in the refrigerator. If possible, protect the top layer with plastic wrap or foil before freezing, to eliminate any unwanted crystalization.
