Side Dishes
This sweet potato spirals recipe transforms humble sweet potatoes into a showstopping side dish with crispy lattice edges and tender, warm filling. The secret lies in thin, even slices that crisp to golden perfection while maintaining a soft interior—no soggy centers here.
I developed this technique after years of perfecting spiralized vegetables, and the difference between restaurant-quality and home-cooked results comes down to precise slicing and controlled heat.
What makes these spirals truly special is their versatility—you can roast them until crispy or air-fry for a lighter texture, all while keeping the warm, spiced filling intact. The lattice pattern isn’t just decorative; it creates structural integrity that holds up beautifully when serving.
Seasoning options are endless, but my go-to blend of olive oil, salt, pepper, and a touch of cinnamon delivers that perfect balance of savory and subtle sweetness.
The result is a dish that looks as impressive as it tastes—crispy, caramelized edges framing tender sweet potato strands that practically melt in your mouth. Whether you're serving them alongside roasted chicken or as a vegetarian centerpiece, these spirals bring visual appeal and satisfying texture to any meal.
The best part? They’re easier to make than you’d think, once you master the slicing technique.
For extra flair, drizzle with a light maple glaze before serving, or sprinkle with toasted nuts for added crunch. This recipe scales perfectly for gatherings, and leftovers reheat beautifully—just a few minutes in the oven to restore that crispy lattice. Let’s get started on creating your next favorite side dish.
Ingredients for sweet potato spirals
Sweet potatoes, olive oil, and a touch of cinnamon—simple ingredients for showstopping spirals.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Sweet Potatoes 🍠 | 2 whole | Medium-sized, peeled and sliced thin |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For tossing and crisping |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked for best flavor |
| Ground Cinnamon 🍃 | ½ tsp | Warm and aromatic |
| Unsalted Butter 🧈 | 2 tbsp | Melted for filling |
| Brown Sugar 🍯 | 2 tbsp | Light or dark preferred |
| Pure Maple Syrup 🍁 | 1 tbsp | Grade B for depth |
| Vanilla Extract 🌸 | ½ tsp | Pure vanilla preferred |
| All-Purpose Flour 🌾 | ¼ cup | For lattice pattern |
| Granulated Sugar 🍬 | 1 tbsp | For sprinkling on lattice |
| Toasted Pecans 🥜 | ¼ cup | Chopped, optional garnish |
The sweet potatoes are everything here. Choose medium-sized ones—they spiralize more evenly than large ones. Look for vibrant orange flesh (the deeper the color, the sweeter the potato). Trader Joe's and Whole Foods usually carry the best varieties, but any grocery store sweet potato works. Peeled and sliced thinly with a mandoline (or sharp knife), they crisp up perfectly. Pro tip: Soak your mandoline blade in hot water for 10 seconds between slices—keeps them from sticking. The cinnamon? Penzeys or McCormick for the best quality, but honestly, any brand will do.
No mandoline? Use a sharp chef's knife—just be patient and take your time. Running out of olive oil? Avocado oil works too, but olive has that perfect fruity note. The filling can be prepped ahead—mix the butter, brown sugar, maple syrup, and vanilla in a small saucepan and warm it gently. Want extra crunch? Swap pecans for walnuts or almonds. The lattice pattern is easier than it looks—just cut the dough into strips and weave them over the spirals. No flour for the lattice? Use crushed cornflakes instead—they add crunch without weighing it down.
Spirals reheat beautifully—just pop them in a 350°F oven for 5-7 minutes until the lattice is crispy again. Store in an airtight container for 3-4 days (the filling stays warm and gooey). Freeze for up to 3 months by wrapping tightly in foil. I always make double batches because these disappear fast—leftovers taste even better the next day as the flavors meld. For extra flair, drizzle with a little more maple syrup before serving.

Step-by-step instructions for sweet potato spirals
Here's how to create those irresistible crispy lattice spirals with a warm, spiced filling inside.
Prepare and Cook the Sweet Potato Spirals
Start by peeling the 2 whole large sweet potatoes and slicing them into ¼-inch thick rounds using a mandoline or sharp knife. Arrange the slices in a spiral pattern on a parchment-lined baking sheet, leaving a ½-inch gap between each slice to allow for expansion.
Preheat your oven to 425°F and brush each sweet potato slice lightly with some of the 0.25 cup extra-virgin olive oil. Sprinkle evenly with 1 tsp of the 1.5 tsp kosher salt and 0.25 tsp of the 0.5 tsp freshly ground black pepper. Bake for 15-18 minutes until the edges begin to crisp and the centers are tender when pierced with a fork.
Remove the spirals from the oven and let them cool slightly. Here's the thing—don't rush this step. The sweet potatoes need to firm up just enough to handle without falling apart when you build your lattice.
Make the Warm Spiced Filling
In a small saucepan, melt the 2 tbsp unsalted butter over low heat. Add the 2 tbsp brown sugar, 1 tbsp pure maple syrup, and 0.5 tsp vanilla extract, stirring until the sugar dissolves completely. Remove from heat and let it cool for 5 minutes—this prevents the filling from cooking the sweet potatoes too quickly.
In a separate small bowl, whisk together the 0.25 cup all-purpose flour and the remaining 0.5 tsp kosher salt and 0.25 tsp ground cinnamon. Gradually whisk in the cooled butter mixture until you have a smooth, thick paste. This filling should be spreadable but not runny—if it's too thick, add 1-2 teaspoons of water to adjust the consistency.
Assemble the Lattice Spirals
Carefully spread 1-2 teaspoons of the spiced filling onto the center of each cooled sweet potato spiral. Gently fold the edges of the spiral inward, creating a neat package. Here's where it gets fun—use a sharp knife to cut a ¼-inch wide strip from each side of the remaining sweet potato slices to create the lattice strips.
Arrange the strips in a crisscross pattern over the filled spiral, alternating directions to create the classic lattice design. Brush the lattice lightly with the remaining extra-virgin olive oil and sprinkle with the remaining 0.5 tsp kosher salt and 0.25 tsp ground cinnamon. Finally, sprinkle 1 tbsp granulated sugar evenly over the top for that perfect caramelized finish.
Bake Until Golden and Crispy
Return the assembled spirals to the preheated 425°F oven and bake for 12-15 minutes until the lattice is deep golden brown and crispy. You'll know they're done when the edges are perfectly crisp and the filling is bubbling through the lattice in some spots—this is what makes them irresistible.
Remove from the oven and let cool for 2-3 minutes before serving. For the final touch, sprinkle with the 0.25 cup toasted pecans just before serving. The contrast of the crunchy lattice with the warm, spiced filling inside is what makes this dish truly special.
Pro Tips For Making Sweet Potato Spirals
- USE A MANDOLINE (or knife): Sweet potato spirals look impressive when they’re even—skip the uneven knife cuts unless you’re okay with jagged edges. A mandoline’s thin setting (about ⅛-inch) gives you consistent, restaurant-quality slices, and it’s faster than you’d think once you get the hang of it. (Yes, even if you’re impatient like me.)
- SALT THE SPIRALS IMMEDIATELY: Freshly sliced sweet potatoes oxidize fast and turn bitter if you wait. Toss them with a generous pinch of kosher salt (about ½ teaspoon per pound) right after cutting, then let them sit for 10 minutes. This also draws out excess moisture so they crisp up better—no soggy middles here.
- DON’T OVERCROWD THE PAN: I learned this the hard way—piling spirals too close steals their heat, and you end up with steamed potatoes instead of crispy edges. Leave at least ½-inch between each spiral, and if your pan is small, work in batches. A 12-inch skillet holds about 8–10 spirals comfortably—any more and you’re asking for trouble.
- ROAST AT 425°F (not higher): Sweet potatoes caramelize beautifully at this temp, giving you a balance of crispy edges and tender centers. Going hotter (450°F+) burns the outsides before the insides cook, while lower temps (400°F) leave them gummy. Flip them once mid-roast—about halfway through the 20–25 minutes—to guarantee even browning. (Your future self will thank you.)
Essential equipment for sweet potato spirals
Spiralizer Essentials
You’ll need a high-quality spiralizer to achieve those perfect, even slices. I recommend the OXO Good Grips model—it’s affordable, easy to use, and handles sweet potatoes beautifully.
For thicker slices, adjust the blade to ¼-inch thickness. Soak the blade in hot water for 10 seconds between batches to prevent sticking. 🍠
No spiralizer? A sharp mandoline with a ¼-inch blade works just as well. If you’re slicing by hand, use a long, thin knife and make thin, even cuts—patience is key here. The goal is consistency so the lattice holds together during baking.
Baking Tools
A parchment-lined baking sheet is non-negotiable—it prevents sticking and makes cleanup a breeze. I use half-sheet pans for even heat distribution. Preheat your oven to 425°F and let it fully acclimate before baking. A lightweight metal cooling rack helps crisp the lattice after baking by allowing air to circulate underneath.
For extra crunch, I sometimes use a wire cooling rack placed over a baking sheet. After baking, I transfer the spirals to the rack to cool—this ensures the bottom stays crispy, not soggy.
A pastry brush is also handy for applying olive oil to the lattice strips before the final bake.
Mixing & Measuring
For the filling, a small saucepan with medium heat is ideal for melting butter and dissolving sugar. I use a whisk to combine the flour and spices, then gradually mix in the cooled butter mixture. A small offset spatula helps spread the filling evenly onto the spirals without tearing them.
Measure ingredients precisely—brown sugar and maple syrup should be weighed for accuracy. A digital kitchen scale makes this easy, but if you’re using measuring spoons, pack the brown sugar firmly into the spoon. For the lattice, a pizza cutter or sharp knife works best for clean cuts.
Optional Upgrades
Want restaurant-quality results? Invest in a food processor to quickly chop pecans for toasting. Toast them in a dry skillet over medium heat for 3-4 minutes until fragrant. A fine-mesh sieve helps dust the lattice evenly with cinnamon and sugar before the final bake.
For extra flair, a drizzling bottle (like a small squeeze bottle) makes it easy to add maple syrup glaze before serving. And if you’re making these ahead, airtight containers with parchment paper between layers keep them crispy for days. 💫

Frequently asked questions
Can I make sweet potato spirals without a spiralizer?
While a spiralizer makes it easier, you can achieve great results with a sharp mandoline or even a long, thin knife. For hand-slicing, cut the sweet potatoes into ¼-inch thick slices and arrange them in a spiral pattern on your baking sheet. Just be patient—even slices are key for that perfect lattice structure.
How do I prevent my spirals from falling apart when assembling?
Let the sweet potato slices cool slightly after the first bake—this helps them firm up. Gently fold the edges inward before adding the filling, and use a small offset spatula to spread the filling. Work quickly but carefully to keep everything intact. If they still feel too soft, bake them 2-3 minutes longer before assembling.
Can I make these ahead of time?
Yes! Assemble the spirals up to 24 hours ahead and refrigerate uncovered. When ready to bake, simply pop them in the oven at 425°F for 12-15 minutes to restore crispiness. For longer storage, freeze the assembled spirals (unbaked) for up to 3 months. Thaw overnight in the fridge before baking.
What if I don't have flour for the lattice? No problem! Use crushed cornflakes or crushed graham crackers instead—they add crunch without weighing down the lattice. For a gluten-free option, try crushed rice cereal. Just
How do I get the lattice extra crispy?
For maximum crispiness, bake the spirals on a wire cooling rack placed over a baking sheet. This allows air to circulate underneath. After the initial bake, transfer them back to the rack and broil for 1-2 minutes at the end—just watch closely to avoid burning. A light spray of olive oil before the final bake also helps!
