This creamy crockpot scalloped potatoes recipe is my husband’s favorite.

He loves ordering these cheesy scalloped potatoes when we dine out.

So I decided to create an easy crockpot version of this dish that you can make at home.

Make this classic potato side dish for special occasions or holiday dinners.

What are scalloped potatoes?

You may know these types of recipes as “au gratin potatoes.”

Some people use the terms interchangeably. But there is a difference!

According to DifferenceBetween.net, scalloped potatoes got their name from the Old English word “collop” which means to thinly slice.

And au gratin potatoes got their name from the French words “grater” and “gratine” which means to scrape, crust, or skin.

Both dishes are baked, but you can cook au gratin potatoes on a grill or boiler.

You cook scalloped potatoes in cream while au gratin potatoes are baked with cheese.

Both feature a creamy cheese sauce. Serve this with chicken, turkey or pork dishes such as:

What variety of potato should you use?

Using Russet potatoes? Make sure to wash and peel them.

If you want to save time by skipping peeling, use Yukon gold or red potatoes.

Do I have to use half-and-half?

To get maximum creaminess, use half-and-half. (If you want to go nuts, use heavy cream.)

If that’s too much, you can use whole milk, but the sauce won’t be as creamy.

Don’t use 2% 1%, or skim milk, or your recipe won’t turn out as rich and creamy.

How to make gluten free scalloped potatoes

Flour: If you’re gluten free, use gluten free all-purpose flour instead of regular all-purpose flour.

My favorite gluten free flour is Bob’s Red Mill Gluten-Free 1-to-1 Baking Flour, which cooks up just like regular flour.

Check out my Best Gluten Free Products List to find more of my favorite gluten free baking products!

Chicken broth: Make sure the broth you’re using is certified as gluten free on the label.

What kind of cheese?

This scalloped potato recipe calls for Gruyère, Mozzarella, and Parmesan, giving this dish a Swiss-Italian flare.

Other scalloped potato dishes use sharp cheddar cheese. If you wish, you can use shredded cheddar instead of Gruyère.

Is shredded cheese gluten free?

According to Very Well Fit both Kraft and Sargento say their shredded cheeses are gluten-free.

But if you have concerns, you should shred your own cheese.

What is seasoned salt?

You can use a store-bought seasoned salt like Lawry’s. (My mom used it on everything.)

Or you can make your own homemade seasoned salt blend from spices in your pantry.
