How to make scalloped sweet potatoes
Step 1: Use a mandolin slicer to slice the sweet potatoes into ⅛th-inch thick rounds.
Step 2: Arrange the sliced sweet potatoes evenly in alternating layers in the baking dish.
Step 3: Melt the butter in a saucepan over medium–high heat. Add the garlic, fresh thyme, salt, pepper, and nutmeg. Saute for 30 seconds until fragrant. Remove the pan from the heat and whisk in the heavy cream.
Step 4: Whisk in a ¼ cup of the Gruyère cheese, and Parmesan until smooth and creamy.
Step 5: Pour the cream mixture over the layered sweet potatoes.
Step 6: Sprinkle the remaining Gruyere over the top. Bake in the oven for 50-60 minutes or until the sweet potatoes are tender. Broil on high for the last 1-2 minutes at the end, until golden brown.

Best tips
Thin slices for a perfect bite: Slice your sweet potatoes thinly, as thicker slices may not cook evenly. This ensures that every layer becomes tender and infused with flavor.
Mandoline slicer precision: Invest in a mandoline slicer if you can. It simplifies the process and guarantees consistently thin sweet potato slices. This step ensures the dish and its sweet potato slices will cook evenly. There is nothing worse than having raw “spots” in your baking dish.
FAQs
Scalloped sweet potatoes are done when you can slide a sharp knife easily into the potatoes.
Your sauce will only split if you use reduced fat milk and cheese. This recipe needs the fat in the heavy cream, parmesan and gruyere cheese to hold the sauce together.
This recipe is perfect for making ahead. Go ahead and fully assemble the dish, then cover and place in the fridge. When ready, remove covering and pop into the oven.
Storage instructions
To keep fresh and safe for later enjoyment, follow these storage and reheating tips:
Fridge: Transfer any leftovers into an airtight container. Store for up to 3-4 days.
Freezer: Place the leftovers in a freezer-safe container or wrap it tightly in freezer-friendly plastic wrap. Freeze for up to 60 days.
Reheating:
- Preheat your oven to 350°F (175°C).
- Transfer the scalloped sweet potatoes to an oven-safe dish.
- Cover the dish with aluminum foil to prevent excessive browning.
- Heat for 20-30 minutes or until the center is hot.
You can reheat smaller portions in a shallow pan on the stovetop over medium heat. Heat for 5-7 minutes until the center is hot. Do not cover the pan to prevent the crusted top from softening. For best results use an oven-safe skillet to pop under the broiler for the last minute or two of reheating.
Although using the oven is best to maintain the texture of this dish, short bursts of 20-30 seconds to reheat in the microwave can work if you are in a hurry. Always gently stir leftovers in between heating when using a microwave.
