Thinly sliced sweet potatoes tossed in a cheesy, garlic cream sauce and baked until tender. Similar to classic au gratin potatoes, a great side dish for family dinner or a holiday meal!
Preheat oven to 400 degrees F, lightly grease a baking dish and set aside. Add sliced sweet potatoes to a large mixing bowl.
2-3 medium Sweet potatoes
In a small saucepan heat the butter over medium-high heat. Once warm add in the garlic and shallot, sauté for 2-3 minutes until fragrant. Add in the fresh thyme, salt, and pepper. Remove from heat and stir in the heavy cream and parmesan cheese, stir until parmesan is melted.
4 tbsp Unsalted butter, 2-3 Cloves of garlic, 1 medium Shallot , 1 tsp Kosher salt, Fresh cracked black pepper, 2-3 sprigs Fresh thyme, 1 1/2 cups Heavy cream , 1 cup Shredded parmesan cheese
Pour the cream mixture over the sweet potatoes, toss well to combine. Arrange potato slices upright in the prepared baking dish, top with any remaining cream sauce.
Bake for 50-60 minutes or until the sweet potatoes are fork tender. Serve immediately garnished with extra fresh thyme.
Notes
*Peel your potatoes for an extra smooth and creamy consistency, skin can be left on if desired.*Use a mandolin for evenly sliced sweet potatoes that bake at the same time. Slicing sweet potatoes by hand makes it hard to get the same thickness and can create slices that are thicker than preferred.*Bake until fork tender for best results, check doneness of potatoes before serving.*Make-Ahead, assemble the gratin up to 1-2 days in advance, cover, and refrigerate. Bake just before serving for the freshest texture.
