Prepping the Sweet Potatoes
The potatoes can be prepped up to 2 days ahead. Just store the rounds in an airtight container filled with water to prevent them from browning. Before baking, drain the water and dry the sweet potato rounds with a clean kitchen towel.
Here’s how to prepare them ahead:
- Gently rinse each potato with warm water to remove any dirt and debris.
- Use a vegetable peeler to remove the skins.
- Place the sweet potato onto a cutting board and trim the ends off.
- Starting from one end, slice the potatoes into ¼-inch thick rounds.
If you have a mandolin, this is a golden opportunity to put it to use.
Browned Butter & Sage
Two very important components of this recipe are butter and sage. The butter is browned in a saucepan and gives each stack a bronzy glow. Sage has an earthy, peppery flavor that pairs beautifully with aged Parmesan.
Both cooked together add an exquisite flavor and make the sweet potato stacks taste like Thanksgiving.
How to Make Sweet Potato Stacks
Below I show you how to prepare the brown butter with sage leaves and assemble these sweet potatoes. Trust me, it’s easy, and once you take a bite, you’ll thank yourself for trying something new.
Preheat the oven to 375F.
Brown the butter
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 each stack with salt, black pepper, and top with 1 tablespoon Parmesan cheese. Add 2 more potato rounds and top the entire 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, top 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.
Set to broil
Remove the pan from the oven and discard the foil. Preheat the oven to broil.
More butter and cheese
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.
The Best Cheese for Sweet Potato Stacks?
Parmesan is one of many options to pair with these sweet potato stacks. Varieties such as Gruyere, sharp Cheddar, and Gouda are also excellent with sage and sweet potato.
