What Are Sweet Potato Stacks

Sweet potato stacks are thinly sliced sweet potatoes layered with Parmesan cheese, drizzled with a sage-infused browned butter, then baked to tender perfection.

Ingredients

These sweet potato stacks are an elegant and impressive dish, that’s relatively simple to make with usual Thanksgiving ingredients like:

Butter: to combine with the sage and create a delicious topping.
Fresh sage leaves: add a Thanksgiving-like mouth-watering flavor.
Garlic cloves: a boost of extra flavor that is always welcome!
Sweet potatoes: peeled and sliced into rounds.
Salt and pepper: for seasoning.
Grated cheese: I use Parmesan. Other great options are Gruyere, sharp Cheddar, and Gouda.

Is your mouth watering yet? Mine too. And with all the delicious flavor no one will even notice or think about it being gluten-free!

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.

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. Now, let’s cook!

1. Prep the oven
First, preheat the oven to 375F.

2. Prep the sweet potatoes
Rinse each potato with warm water to remove any dirt and debris. With a vegetable peeler, 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.

3. Brown the butter
In a medium saucepan, you melt the butter, add sage and garlic, 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.

4. Assemble
Now, you place 2 sweet potato rounds in the bottom of a baking dish and sprinkle them with salt, black 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.

5. Bake
Cover your dish with foil and bake for 25 minutes or until the sweet potato stacks are fork-tender.

6. Set to broil
Remove the pan from the oven and discard the foil. Preheat the oven to broil.

7. More butter and cheese
Make these potatoes tastier by drizzling the remaining butter and sprinkling with additional cheese.

8. Glow up
Broil the potatoes for 3 minutes or until the cheese melts. Remove 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.
