How to Make Sweet Potato Stacks

Here’s how to prepare the brown butter with sage leaves and assemble these sweet potato stacks:

Prep the sweet potatoes
Before cooking the sweet potatoes, peel them and slice them into ¼-inch thick rounds. If you have a mandolin, this is a golden opportunity to put it to use.
Brown the butter
In a saucepan, melt the butter, add the sage and garlic, and cook until the butter is foamy and starting to brown. Carefully remove the sage leaves and place them on a paper towel-lined plate.
Assemble
Place 2 sweet potato rounds in the bottom of a baking dish and sprinkle them with salt, pepper, and cheese. Add 2 more potato rounds and top each stack with ½ teaspoon of the browned butter. If you used a mandolin, 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.
Bake
Cover your dish with foil and bake in a preheated oven at 375F for 25 minutes or until the sweet potato stacks are fork-tender.
Broil
Reheat the oven to broil. Make these potatoes tastier by drizzling the remaining butter and sprinkling with additional cheese. Broil uncovered for 3 minutes or until the cheese melts. Top with the reserved, butter-poached sage leaves.

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.

More Unforgettable Thanksgiving Sides

Creating a Thanksgiving menu can be a daunting task if it’s your first time. You need a solid recipe for stuffing as well as a few sides and desserts to follow, like this frozen pumpkin pie dessert. Of course, you can’t forget about cranberry sauce. It’s essential. In my table, you’ll also find Southern mashed potatoes and roasted fall vegetables. So good!
