With beautiful layered potatoes that compliment nearly any meal, this is guaranteed to be a show stopper. If layers are your thing, try layering apples and sweet potatoes.

Thinly sliced sweet potatoes and Yukon Gold potatoes are baked in a creamy sauce then topped with cheese. When the sweet potatoes absorb the cream, it leaves them with the perfect balance of savory flavors and hint of natural sweetness.

This casserole is easy enough to serve for a family dinner and gorgeous enough for the holiday table. The layers of sweet potatoes and regular potatoes come together and form a delicious, yet impressive casserole.

Not to mention, this sweet potato gratin is the perfect side dish to just about any main course. I love serving it with steak marsala, pork tenderloin or stuffed chicken breast. Of course, It will also go great with ham or turkey for your next holiday dinner!

While I love the flavors of a mashed sweet potato casserole, the potatoes in this casserole will soften but still maintain their shape so that you can serve it as a beautiful block of potatoes.

An added benefit if you are serving this with other sides, is that it needs to rest for at least 15 minutes before cutting which gives you enough time to cook some dinner rolls.

Ingredients you’ll need for easy scalloped potatoes

• Potatoes – A combination of sweet potatoes and Yukon gold potatoes not only tastes good, but it creates beautiful layers in the casserole.
• Fresh herbs – Using fresh parsley and fresh thyme is an easy way to elevate these scalloped potatoes
• Cream – Pairing heavy cream with half-and-half ensures you get all the creamy flavor without the casserole becoming too dense.
• Cheese – I prefer gruyère cheese but feel free to experiment with parmesan cheese, Monterey jack, sharp cheddar cheese, or other types of cheeses.

Pro tip: If you don’t have half-and-half, for each cup of half-and-half, substitute ¾ cups whole milk and ¼ heavy cream.

Can I prep sweet potatoes ahead of time?

Cutting the potatoes in advance is a great way to save some time. However, raw potatoes will turn brown so it’s best to store cut potatoes in cold water in the fridge.

Simple steps for creating scalloped potatoes

Step 1: Get everything ready

Preheat the oven, spray a large casserole dish, and thinly slice the potatoes with a mandolin or food processor. You an also use a knife, just try to get them as thin as possible.

Step 2: Layer

Arrange some of the Yukon potatoes into the bottom of the baking dish. Top with herbs and butter.

Step 3: Repeat

Alternating between Yukon and sweet potatoes, finish layering the casserole.

Step 4: Final touches

Pour the cream mixture over the layers of potatoes, top with cheese, and bake, covered for 40 minutes, then uncover and top with cheese and bake until it is golden brown.

Pro tip: Let these gruyere scalloped potatoes sit at least 15 minutes before cutting with a sharp knife. This way, the layers can set and you won’t be left with a mess.

Potato pointers

• Sprinkle some brown sugar or drizzle some maple syrup on top of the potatoes before baking for a little sweetness.
• You can heat these scalloped potatoes up as leftovers the next day.
• If you’re having trouble slicing the potatoes, try a mandolin slicer.
