3medium sweet potatoes, peeled and sliced into ¼-inch thick rounds
1teaspoonsalt
1teaspoonblack pepper
¼cupParmesan cheese, grated
Instructions
Preheat the oven to 375F.
In a medium saucepan, melt the butter over medium-high heat. Add the sage and garlic. Reduce the heat and cook for 5 minutes until the butter is foamy and starting to brown.
Carefully remove the sage leaves and place them on a paper towel-lined plate.
Place 2 sweet potato rounds in the bottom of a baking dish. Sprinkle the stacks with salt, black pepper, and 2 tablespoons cheese. Add 2 more potato rounds and top each stack with ½ teaspoon of the browned butter. *If you are using mandolin sliced potatoes, the slices will be thinner, so you'll probably wind up stacking 4 rounds at a time, topping with cheese, and then top with another 4 slices.
Cover the dish with foil and bake for 25 minutes or until the potato stacks are fork-tender. Remove the pan from the oven and discard the foil. Preheat the oven to broil.
Drizzle the remaining butter over the potatoes and sprinkle with additional cheese. Broil the potatoes for 3 minutes or until the cheese melts.
Remove the potatoes from the oven and place the potato stacks onto a platter. Top with the reserved, butter-poached sage leaves and serve.
