Why You’ll Love Sweet Potato Stacks
Thin, mandoline-sliced sweet potatoes 🍠 meet a slow roasted garlic confit 🧄 in this sweet+savory side that’s completely irresistible. The sweet potatoes bake into tender layers that are crispy on the outside and buttery on the inside. Meanwhile, garlic confit and freshly grated Parmigiano 🧀 infuse the stacks with rich, savory flavor, perfectly balancing the natural sweetness of the potato. You can highlight fall flavors 🍂 with fresh sage and thyme 🌿, or give them a traditional twist with butter, cinnamon, and a few toasted marshmallows. Serve them at your holiday gathering for an elevated take on the classic, or make a few stacks for steak night 🥩. Either way, you’ll definitely want these in rotation year-round 👩🍳.
Ingredients
🍠 Sweet Potatoes: Peeled sweet potatoes are thinly sliced with a mandoline so the edges crisp up and the centers stay tender.
🫒 Olive Oil: Helps every layer brown beautifully and gives it that signature crispy edge.
🧄 Garlic: A roasted garlic confit infuses into the potatoes and gives each bite savory depth.
🧀 Parmigiano: Adds a salty, nutty crust and melts into the layers as the stacks bake. Freshly grated works best.
🧂 Salt + Pepper: Simple seasoning is all you need to make every layer shine.
Nonna’s Tip 🍠
Instead of coating the sweet potatoes with garlic confit in a bowl, spread them on a parchment lined baking sheet then massage in the garlic, oil, and parm for maximum coverage.

Common Questions
A mandoline works best, plus it’s a fun kitchen tool to have in your arsenal! However, if you have some skills a sharp knife will do—just keep the slices as even as possible so they cook uniformly.
Absolutely! You can prep the garlic ahead, assemble them in the muffin tin, cover and refrigerate up to 24 hours in advance. Then, bake them in the oven just before you’re ready to serve.
Warm them in a 350F (175C) oven for 5-8 minutes or air fry them for 3–4 minutes until the edges crisp back up.
Sure! Bake and let cool completely before freezing. Then, reheat in the oven or air fryer until warmed through.
The muffin tin is super helpful in keeping the shape of the stacks. However, you could bake then free-form on a parchment lined baking sheet in a pinch.
Sweet Potato Stacks
Ingredients
- 2 medium sweet potatoes, peeled and sliced thin with a mandoline
- 3 tablespoons olive oil
- 1 bulb roasted garlic
- salt + pepper, to taste
- ½ cup Parmigiano cheese
Instructions
- Preheat oven to 400F (200C). Cut off the top of a bulb of garlic making sure to expose every clove. Add a pinch of salt + olive oil and roast until soft. This should take 30-40 minutes and can be done days ahead, too.
- While the garlic is roasting, work on making the stacks. Peel the sweet potato, and slice it thin on a mandoline. Always use the guard it comes with as you get closer to the bottom.
- When the garlic has roasted (and cooled) squeeze it in a bowl into the olive oil and mix well so it’s incorporated.
- Add the garlic + oil mix on top of the sweet potatoes with salt, pepper, and Parmigiano. Note: I like to place the sweet potatoes slices flat onto a parchment lined baking sheet so they can soften a bit. It's also easier to incorporate the seasonings more evenly vs. using a bowl. Massage the garlic, oil, and Parmigiano well into each slice.
- Stack the slices in a muffin tin. Bake covered for 20 minutes and uncovered for an additional 20-25 minutes, or until golden.
Nonna’s Notes
- Dairy-free: Swap Parmesan for a dairy-free hard cheese, or eliminate it altogether.
- Trad bake: Make a traditional holiday version with cinnamon, butter, and brown sugar. Then, top with a marshmallow toward the end of your baking time for a sweet treat.
- Buttery goodness: Instead of oil, you could also bake these with butter for deep, rich flavor.
- Spices: Warm up this recipe with spices such as smoked paprika, chili powder, or cinnamon.
- Fresh herbs: Use fresh herbs like sage, thyme, or rosemary for Fall flavor. Additionally, you could use parsley for a bright, fresh take.
