Instructions

Preheat Oven: Preheat your oven to 350°F (175°C) and position the oven rack in the middle to ensure even baking.
Prepare Sweet Potatoes: Peel the sweet potatoes and use a mandoline slicer to cut them into thin 1/8-inch slices for uniform cooking and layering.
Grate Cheeses: Finely grate the Gruyère and Parmesan cheeses, then combine them in a bowl to mix thoroughly.
Make Cream Mixture: In a small pan, combine the heavy cream, minced garlic, salt, pepper, ground cinnamon, ground nutmeg, and Italian seasoning. Heat on high, stirring occasionally, and remove from heat just before it reaches a boil to preserve the flavors and prevent curdling.
Grease Baking Dish: Lightly grease a heavy, oven-safe skillet or large baking dish with olive oil to prevent sticking and aid browning.
Assemble Layers: Start with a layer of sweet potato slices in the pan, overlapping slightly. Spoon some of the warm cream mixture over the potatoes, then sprinkle a portion of the combined cheese on top. Repeat this layering process three more times for a total of four layers, reserving about an inch of space at the top of the pan to prevent bubbling over.
Bake: Place the assembled dish in the oven and bake for 60 to 75 minutes. The longer baking time results in a dark golden cheese crust and thickened cream. The sweet potatoes should be tender when tested with a toothpick.
Rest and Serve: Let the scalloped sweet potatoes rest for about 10 minutes after removing from the oven to allow the dish to set before serving. Enjoy warm as a delicious side dish.

Notes

The baking time may vary depending on your oven and the type of dish used; keep an eye on the cheese browning.
Using a mandoline slicer ensures evenly thin slices, which cook uniformly and create a better texture.
Be careful not to boil the cream mixture to avoid separation or scorching.
Gruyère and Parmesan provide a balanced nutty and sharp flavor; substituting with other cheeses will alter the taste and texture.
You can prepare this dish a few hours ahead of time, keep it refrigerated, and bake just before serving, adjusting the baking time slightly.
