Cheesy Scalloped Sweet Potatoes Recipe [Video]

Scalloped Sweet Potatoes are a combination of two favorite potato dishes: scalloped potatoes and sweet potato casserole. Making scalloped sweet potatoes is easy and perfect for the holiday table with both sweet and savory flavors. This delicious recipe has the natural sweetness of the potatoes and the creamiest garlic buttery sauce to create a smooth inviting flavor to go with any meal.

Though nobody is quite certain who invented scalloped potatoes, some say that they originated in England while others say they are French. We do know that there is an old English word, collops, that means slices of meat. In fact, in the UK, there is a dish called collops that is made with thick, fried sliced potatoes. Then, there is the Irish potato collops that includes bacon. 

For this yummy sweet potato gratin recipe, all you need are a few ingredients including sweet potatoes, cheese, butter, flour, milk, cream, and some herbs and spices. It is so good, you are going to want to print this recipe card so you can make it again. Your whole family will love this even if they are not a big fan of sweet potatoes alone. 

Whether you are looking for a perfect holiday meal for Thanksgiving or Christmas dinner, or just a weekend dinner, this side dish is totally a winner. It is a favorite of mine because it is creamy, cheesy, and very delicious!

Cheese and spuds are already such a perfect combination! However, this casserole just takes it to the next level by baking it with a generous amount of milk and sautéed herbs. Also, it is loaded with three types of cheeses to make it extra creamy! Simply put, this dish is extraordinarily savory and mouthwatering.

I love baking it and sharing it with my neighbors and friends. That is why I am also sharing this recipe with you and I hope you have a good time making and eating it as much as I did.

Ingredients needed:

Each of the ingredients was chosen to make the perfect blend of flavors and textures in this scalloped sweet potato recipe. Once you have gathered up the ingredients listed here, find the handy recipe card at the bottom of the page for the instructions and measurements.

  • Thinly sliced sweet potatoes: Peeled and sliced as thin as you can with a sharp knife or mandolin slicer. Try for about 1/8 of an inch. 
  • Cheddar cheese: Make your own freshly shredded cheddar cheese for the best taste and texture. 
  • Mozzarella cheese: Same here, shredding your own cheese is best.
  • Parmesan cheese: Once again, freshly shredded cheese gives you the most incredible flavor.
  • Minced garlic cloves: You need garlic to balance out the sweetness in this dish. 
  • Unsalted butter: If you only have salted butter, just omit the salt from the ingredients.
  • All-purpose flour: Any kind of flour will do. It is just for thickening.
  • Whole milk: Mixed with the cream, this makes the perfect cheesy milk sauce.
  • Heavy cream: Along with the milk, adding heavy cream will make your potatoes extra creamy and thick.
  • Cinnamon: Freshly ground cinnamon would be awesome, but you can use store-bought.
  • Ground ginger: Ginger goes with cinnamon and nutmeg for a delicious blend of fall spices.
  • Nutmeg: Made from the seeds of the nutmeg tree, this spice has a sweet and nutty flavor.
  • Finely chopped fresh rosemary: For garnish, this addition is just an option but one that we think is necessary for a unique taste.
  • Sea salt
  • Ground black pepper

Frequently asked questions

What are scalloped potatoes?

The word scalloped is the method in which the spuds are thinly sliced and layered. They are then baked in a milk sauce in the oven until the top turns golden brown. In North America, this is one of the main side dishes on the Thanksgiving table or Easter dinner. 

How do I choose sweet potatoes?

The best sweet potatoes are firm but not hard with smooth skin and no blemishes. Do not get any with cracks or soft spots. They should also have a bright color and the skin should not be wrinkled or dry. You should also try to get sweet potatoes that are close to the same size, so they cook evenly. According to Harvard University, these vegetables have plenty of health benefits. Firstly, they are loaded with Vitamin A – in the form of beta-carotene, Vitamin B6, Vitamin C, and others.

What is the difference between scalloped potatoes and au gratin potatoes?

If you love scalloped potatoes, you probably already know the answer to this question. The difference comes down to cheese. While scalloped potato recipes are always made with a milk or cream sauce, they do not always include cheese and do not typically have a crunchy topping. Au gratin potatoes always have shredded cheese and a crunchy topping of breadcrumbs. 

Can I use regular potatoes?

Any kind of thinly sliced potatoes will work for this recipe. There are over 200 types of potatoes in the United States alone. Yukon gold potatoes would be perfect for this easy scalloped potato dish. You could also use red, blue, yellow, or white potatoes of any variety. The one that is not as good to use is russet or Idaho potatoes because they tend to get mushy.

Why are my scalloped potatoes watery?

You may have not drained the potato slices well after rinsing them. To ensure this does not happen, place them on paper towels or a clean kitchen towel and press them dry after draining. Of course, it is possible that you added too much liquid, but this is doubtful if you followed the recipe. Add some flour to your cream mixture and heat it until it is thick enough.

Scalloped Swee Potatoes vs Sweet Potato Casserole

This is another frequent question I get.

Classic Sweet Potato Casserole is pretty much always made with crunchy pecans and topped with marshmallows or brown sugar. In addition, it tends to be on the sweeter side, because it combines brown sugar or maple syrup. Also, this one is made with mashed sweet potatoes. While for scalloped sweet potatoes, you have to slice the spuds thinly.

How to store leftovers:

  • Store: You can store your leftover scalloped sweet potatoes in an airtight container in the refrigerator. They will last for three to four days.
  • Freeze: If you cannot finish it in a few days, you can freeze scalloped sweet potatoes for up to three months. Just pack it into a freezer bag or another freezer-safe container.
  • Thaw: Try to remember to thaw your frozen leftovers in the fridge overnight for the best consistency and taste.
  • Reheat: To reheat the whole thing, place it in the oven, covered, for 20 to 30 minutes at 350 degrees F. For a single serving, microwave for 45 to 90 seconds.
