Crispy Parmesan Thyme Sweet Potato Stacks. Made simply with sweet potatoes, butter, thyme, garlic, a bit of cheese, and of course, some flaky sea salt and black pepper. Each cute little sweet potato stack is perfect and so delicious. The secret…thinly slicing the potatoes and layering them together to create stacks. As each stack bakes away, the edges of the potatoes get extra crispy, while the middle turns buttery. With hints of thyme, parmesan, and garlic throughout, these stacks are sure to be a hit. Double the recipe – one batch is just never enough.

When it comes to Thanksgiving, I love a traditional meal with a handful of fun sides. But something I almost never switch up? The sweet potato casserole. I’ve been making this sweet potato casserole with sweet ‘n’ savory bacon pecans for years. It’s absolutely delicious and one of my favorite casseroles on the table.

This year though, I’m switching things up! We’re going the savory route with these crispy, cheesy, sweet potato stacks!

These are so different from a classic sweet potato casserole, but so so delicious!

Here’s what you’ll need to make these crispy sweet potatoes

– butter, salted is always my go-to!

– garlic, just a small amount this time.

– sweet potatoes, try to find medium size potatoes that are about the width of a cupcake mold.

– fresh thyme and oregano, but if you don’t have fresh, dried works too! I love savory thyme with sweet potatoes.

– a mix of Parmesan and manchego cheese, but using all parmesan works too.

– flaky sea salt, and plenty of it.

– freshly cracked black pepper.

And that’s it, these stack style sweet potatoes don’t need much to make them delish.

The details

Before you start, locate your mandoline or a very sharp knife. A mandoline is really best for this recipe, so if you have one, use it! If not, you’ll need to very thinly slice each sweet potato using a knife. It’s doable for sure, but the mandoline makes cutting the potatoes into thin even slices very easy!

Now, thinly slice each sweet potato into almost paper-thin slices. Honestly, the thinner you can go the better! Cutting the potatoes into thin slices allows the edges to become perfectly crisp, almost potato chip-like, which yes, is addictingly delicious.

Once I have the potatoes sliced, I like to melt together the butter and garlic in a small sauce pot on the stove. I found this to take away any intense garlic flavor and instead leave you with just the right amount.

Now, toss everything together in a bowl, and toss it well. Make sure all the sweet potato slices are evenly coated in the butter, herbs, and parmesan.

Layer the sweet potatoes into a stack in a standard cupcake pan. Fill each mold to the very top to get a nice tall stack. It might seem like a lot, but the stacks shrink down as they bake.

As the stacks bake away in the oven, the kitchen will smell incredible. Buttery, with hints of garlic and thyme in the air.

Even better than the smell…these stacks really are so good. It’s the crispy chip like edges and sweet, soft center – DELICIOUS! And the sea salt on top just makes them addicting.

While I’m excited to serve these up for Thanksgiving this year, the options for these sweet potatoes are endless. They can be paired with so many types of dinners, beef tenderloin would be especially delicious!

My only recommendation is doubling the recipe, one pan of potato stacks never seems to be enough. They’re always the first thing to disappear on the table.

Ingredients

  • 1 stick (1/2 cup) salted butter
  • 1-2 cloves garlic, grated
  • 6 medium sweet potatoes, cut into 1/8 inch thick slices
  • 2 tablespoons chopped fresh thyme
  • 2 teaspoons chopped fresh oregano
  • 1/2 cup grated parmesan cheese
  • 1/4 cup grated manchego cheese
  • kosher salt and black pepper

Instructions

  • 1. Preheat the oven 400° F. Lightly grease a 12 cup muffin tin.
    2. In a small pan, melt together the butter and garlic until fragrant, about 5 minutes.
    3. In a large bowl, combine the sweet potatoes, garlic butter, thyme, oregano, parmesan, manchego, and a large pinch each of salt and pepper. Toss well to coat. Layer the sweet potatoes evenly in the prepared muffin tin, stacking the layers all the way to the top. The sweet potatoes will shrink down as they cook.
    4. Cover with foil and place on a baking sheet. Transfer to the oven and roast for 40 minutes. Remove the foil and continue cooking another 20-25 minutes or until the potatoes are tender and golden. Run a butter knife around the edges of each stack to release them. Serve immediately, sprinkled with a little sea salt.

    1. Hey Ally,
      You could certainly assemble ahead of time, but you would want to bake these fresh before serving. Let me know if you give the recipe a try! xTieghan

  1. I love you! Thanks for being an inspiration. I made these yesterday and they are great but mine burnt a bit on the bottom – thinking I used too much or not the correct greaser?? Thank you!

    1. Hey Bethany,
      Sorry to hear this! Was there anything you adjusted? Next time try using a higher rack in your oven. I hope this helps! xTieghan

  2. Made these instead of latkes, for Hanukkah. Two large sweet potatoes (using a mandolin) was all I needed for 12 . My stacks weren’t that neat and they still came out so delicious!! Will make again, for sure!
