These impressive Scalloped White and Sweet Potatoes are a make-ahead dish perfect for any special occasion. It’s the kind of recipe that shows you went all-out but the time and effort is done before the event. That means you get to relax and accept the compliments at the party. Take this to your next potluck dinner and I guarantee people will ask for the recipe. Many people have told me they make this recipe in advance and freeze it!
Special occasions and going all out don’t need to mean long ingredient lists or unusual ingredients. To me it means making something you love that you wouldn’t make every day. That could be making the same special dish year after year or challenging yourself with something new. That’s up to you.
Flourless Scalloped Potatoes
Scalloped potato recipes are often made with flour but that can be replaced with rice flour, a blend or cornstarch. This recipe doesn’t use flour but combines whipping cream and Gruyere cheese to create a luscious, decadent side dish. Hold the low-fat, non-fat recipes for now, a special occasion calls for all the fat and all the flavour.
Sweet Potatoes vs Yams
Naturally the contrast of the orange and white flesh is what makes the presentation so be sure that’s what you buy. With the popularity of sweet potato fries you would think sweet potatoes have orange flesh. Wouldn’t you?
Being a foodie I thought yams were orange and sweet potatoes were white but I checked to be sure. After my research I learned it’s actually more complicated than that. Sweet potatoes come in varieties and the flesh varies from white to orange and even purple. Yams are a white tuber not commonly available, who knew! Then because of an old labelling law some sweet potatoes are labelled as yams. When they came to North America shippers and suppliers needed to distinguish them from potatoes so they called them yams. (I’m sure that is one of those ideas that sounded good at the time.)
My advice is to buy something orange and something white and you’ll be happy. If you’re interested in learning more Gerard over at ManyEats wrote this comprehensive post on the History of Sweet Potatoes. He also talks about the difference between sweet potatoes and yams. It’s a good read!
The good thing is you don’t need to know any history to make these Scalloped White and Sweet Potatoes. I’d love to hear in the comments how your dish turned out.

- Using a sharp knife cut the potatoes into serving size squares. Reheat using one of the following methods:
- *Place squares in 350°F oven for 10 minutes and serve warm. Or, place the squares on a baking dish, sprinkle with parmesan cheese (optional) and broil for 5 minutes until browned on top. Turn off the broiler but leave in the oven for another 10 minutes to ensure they are heated through. Serve immediately.
