Last week, I had a sudden craving for some cheesy-creamy potatoes. I quickly ran to the supermart and grabbed the gluten free scalloped potatoes box.

As you can guess, the gluten-free one cost me almost DOUBLE the money and the taste was not even worth the price! And just like most of the ready-to-eat dishes from the supermarket, this one also tasted kind of “artificial”

This leads me into a quest for the best gluten-free scalloped potatoes recipe. I have perfected this one over the months, and today I’m going to share it with you guys… 😉

This is a delicious side dish that anyone can enjoy, not just restricted to those on a gluten-free diet. It is perfectly suited for special occasions and holiday menus (always been a part of my Christmas Eve spread!)

Scalloped Potatoes VS Au Gratin Potatoes

Contrary to popular belief, Au Gratin potatoes are quite different from scalloped potatoes. Here are the reasons:

  • Scalloped potatoes are slightly thicker than the au gratin potato.
  • Au Gratin Potatoes are always layered with cheese and topped with bread crumbs.
  • Scalloped potatoes have a more creamy sauce and do not have the breadcrumb topping (and hence they are gluten free). They sometimes contain cheese, however not always.

That said, let’s quickly jump to the ingredients.

Ingredients for Gluten Free Scalloped Potatoes

  • 3 lbs. of yukon gold potatoes, peeled and thinly sliced  (1/8 inch thick)
  • One cup 2% milk (or dairy-free substitute)
  • One tbsp unsalted butter
  • One garlic clove (large, minced)
  • One tbsp fresh thyme
  • One cup shredded white cheddar cheese (aged)
  • 1/2 cup grated parmesan cheese
  • A dash of nutmeg
  • Salt & pepper to taste

How to Make Gluten Free Scalloped Potatoes

Step 1: Slicing the Potatoes

Wash & scrub the potatoes with a brush to get rid of any dirt.


Peel the potatoes and slice them into 1/8″ thick slices. I prefer to use a mandoline for this, but you may use a slicer or simply a knife.

Tip: To ensure the right thickness, stack 2 quarters on top of each other and line up next to the potato. If your potato slice is thicker than this, you need to keep cutting!)

Once the potatoes are sliced add them to a big bowl of cold water. This will allow some of the starch to get out of the potatoes, and also prevent them from browning. Pat dry the slices before adding them to a dish.

Step 2: Making the Sauce

In a small sauce pan add milk, garlic cloves, nutmeg and some fresh thyme. After it comes to a boil, add butter. Stir it smoothly till the butter melts, and keep it aside.

But I want a thicker sauce…

Don’t worry, I’ve got you covered! Just follow these steps to make a rich creamy sauce for your gluten free scalloped potatoes:

  • Take 2 tbsp milk from the existing mixture and place it in a bowl along with 1 tbsp of cornstarch (you may also use rice flour or sweet rice flour).
  • Using a fork, mix the mixture together until there are no lumps left.
  • Pour the cornstarch sauce back into the milk mixture and stir together.
  • Cook the sauce for 1 minute to achieve a thick consistency.

Step 3: Layering & Baking

Layer the potatoes, cheese, toppings, seasonings and add more potatoes on top.

After slicing, potatoes may turn brown if left out in the open air. Place them in a bowl of water to prevent this from happening. You can refrigerate the bowl for up to 24 hours.

Can you prep the scalloped potatoes in advance?

You can surely prep the gluten free scalloped potatoes ahead of time and reheat before serving. Feel free to make the casserole up to 1 day before planning to serve. Refrigerate the sauce in a container and store the potato slices in a bowl of water.
