Ingredients

• 4 medium-sized Sweet potatoes
• 4 tablespoons Unsalted butter
• 0.25 cups Dark brown sugar
• 1.5 cups Heavy cream
• 0.5 teaspoons Ground cinnamon
• 0.25 teaspoons Ground nutmeg
• 0.5 teaspoons Salt
• 1 tablespoon Fresh thyme leaves
• 0.25 cups Grated Parmesan cheese
• 0.5 cups Panko breadcrumbs

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with butter or cooking spray.

Step 2

Peel the sweet potatoes and slice them into thin rounds, about 1/8-inch thick. Use a mandoline slicer for evenly sliced pieces, if available.

Step 3

In a small saucepan over medium heat, melt the butter. Stir in the dark brown sugar, heavy cream, cinnamon, nutmeg, and salt. Cook for 2-3 minutes until fully combined and the sugar has dissolved. Remove from heat and set aside.

Step 4

Layer half of the sweet potato slices evenly in the prepared baking dish. Pour half of the sugar glaze mixture over the potatoes, spreading it evenly with a spatula. Sprinkle with half of the fresh thyme leaves.

Step 5

Repeat the layering process with the remaining sweet potato slices and sugar glaze mixture. Sprinkle the remaining thyme leaves on top.

Step 6

Cover the baking dish with aluminum foil and bake in the preheated oven for 30 minutes.

Step 7

While the sweet potatoes are baking, mix the breadcrumbs and Parmesan cheese in a small bowl.

Step 8

After 30 minutes, remove the foil from the baking dish and sprinkle the breadcrumb and Parmesan mixture evenly over the top.

Step 9

Continue baking uncovered for an additional 15 minutes, or until the topping is golden brown and the sweet potatoes are fork-tender.

Step 10

Remove the gratin from the oven and let it rest for 5-10 minutes before serving. Garnish with additional thyme leaves, if desired.
