Recipe Information
Ingredients
- 2 lbs Sweet potatoes
- 2 cups Heavy cream
- 2 pieces Garlic cloves
- 1 tbsp Fresh thyme
- 1 tsp Salt
- 0.5 tsp Black pepper
- 1 cup Gruyère cheese
- 0.5 cup Parmesan cheese
- 1 tbsp Unsalted butter
Instructions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with the unsalted butter.
Peel the sweet potatoes and slice them thinly into rounds, approximately 1/8-inch thick. Use a mandoline slicer for consistent slices, if available.
In a medium saucepan, combine the heavy cream, minced garlic, thyme, salt, and black pepper. Heat over medium-low heat and bring just to a simmer. Turn off the heat and set aside for the flavors to infuse.
Layer one-third of the sweet potato slices in the prepared baking dish, slightly overlapping the slices. Sprinkle one-third of the Gruyère cheese and one-third of the Parmesan cheese evenly over the layer.
Repeat the layering process two more times, finishing with a cheese layer on top.
Pour the infused cream mixture evenly over the sweet potatoes, ensuring it seeps through all the layers.
Cover the baking dish tightly with foil and bake in the preheated oven for 30 minutes.
Remove the foil and continue to bake for an additional 15 minutes, or until the sweet potatoes are tender and the top is golden brown and bubbly.
Let the gratin rest for 5-10 minutes before serving. Garnish with additional thyme if desired.
