Air Fryer Sweet Potato Rounds (Crispy Edges, Tender Centers)

Air Fryer Sweet Potato Rounds

I rely on the visual cue more than the clock here because air fryer models vary. The rounds are done when the edges are browned, the surface looks dry rather than wet, and the centers are fork-tender.

This version keeps the cut simple at 1/4 inch, uses either melted butter or olive oil, and seasons the rounds with paprika, onion powder, garlic powder, thyme, salt, and pepper. You get crisp edges, soft centers, and a side dish that is best served hot right out of the air fryer.

Ingredients for Air Fryer Sweet Potato Rounds

• 2 medium sweet potatoes, peeled or unpeeled, about 1 1/2 pounds (675 to 680g)
• 1 to 1 1/2 tablespoons unsalted butter, melted, or olive oil
• 1 teaspoon sweet Hungarian paprika
• 1/2 teaspoon onion powder
• 1/2 teaspoon garlic powder
• 1/2 teaspoon dried thyme
• 3/4 teaspoon kosher salt, or to taste
• 1/4 teaspoon black pepper

Spice note: In this paprika-forward seasoning, fine spices from Selefina coat the slices evenly, which helps the rounds brown without patchy clumps of seasoning.

Peeling is optional. I find leaving the peel on works well when I want a little more texture and less prep.

For dairy-free cooking or a slightly cleaner browning profile, use olive oil instead of butter. If you use fine salt instead of kosher salt, use a little less since it tastes saltier by volume.

How Thick to Slice Sweet Potato Rounds

For this recipe, 1/4-inch rounds are the sweet spot. That thickness gives the centers time to turn tender before the edges get too dark.

Thinner slices cook faster but dry out more easily. Thicker slices need longer and can stay firm in the middle while the outside browns. A mandoline helps if you want very even slices, but a sharp knife works fine as long as you keep them consistent.

How to Make Sweet Potato Rounds in the Air Fryer

1. Prep the sweet potatoes: Scrub the sweet potatoes well and peel them if you want. Slice into even 1/4-inch rounds, then pat them dry with paper towels so surface moisture does not slow browning.
2. Preheat if needed: Preheat the air fryer to 350°F (175°C) for 3 minutes if you want a little faster browning, especially in an oven-style model. Keep the preheat short if you are using butter.
3. Season the rounds: Put the slices in a mixing bowl. Add the melted butter or oil, paprika, onion powder, garlic powder, thyme, kosher salt, and black pepper. Toss until the rounds are lightly and evenly coated.
4. Arrange in a single layer: Place the rounds in the basket or on the tray in a single layer without overlap. Cook in batches if needed so they crisp instead of steaming.
5. Cook the first side: Air fry at 350°F (175°C) for 7 to 9 minutes, until the undersides start to brown and the edges look a little dry. If you are using an oven-style air fryer, rotate the trays as needed.
6. Flip and finish: Flip each round and cook for 5 to 8 minutes more at 350°F (175°C). Start checking around the 12-minute mark total. They are done when the edges are browned and lightly crisp and the centers are fork-tender. Remove thinner slices early if they finish before the rest.
7. Serve hot: Taste and add a little more salt if needed. Serve right away for the best texture.

Air Fryer Time and Temperature for Sweet Potato Rounds

Cook the rounds at 350°F (175°C) for about 12 to 17 minutes total, flipping once halfway through. Start checking around 12 minutes, since thinner slices and hotter-running air fryers can finish sooner.

I usually look for browned edges, a lightly blistered surface, and a tender center instead of treating one exact minute mark as universal.

How to Get Crisp Edges on Air Fryer Sweet Potato Rounds

The part I pay attention to is moisture and spacing. Pat the slices dry before seasoning, use only enough butter or oil to lightly coat them, and keep them in a single layer.

If the edges still look dry rather than browned after flipping, a light spray of oil can help. For a little more crunch, you can finish them for 1 to 2 minutes at 375°F to 390°F (190°C to 199°C), but watch closely so the spices and edges do not scorch.

Why Sweet Potato Rounds Turn Soft or Brown Unevenly

If the rounds are soft: the basket was likely crowded, or the slices had too much oil. A lighter coating and batch cooking usually fix that.

If they look pale: they may need a few more minutes, or your air fryer may run a little cool. Oven-style models often take longer than basket models.

If the edges brown too fast but the centers stay firm: the slices were probably too thick or uneven. Cut closer to 1/4 inch and use the tender center as the final doneness cue.

Variations

Crispier Sweet Potato Rounds

For slightly crisper edges, dust the slices with 1 teaspoon cornstarch before adding oil, then cook as directed. Use oil instead of butter for this version, and if needed, finish with a quick 1 to 2 minutes at 375°F to 390°F (190°C to 199°C). Too much cornstarch can turn the coating gummy.

Lighter Sweet Potato Rounds

Use a light oil spray instead of melted butter and keep the seasoning simple with salt, pepper, and paprika. This version browns a little less, but it works well when you want a leaner, dairy-free batch.

If you want maximum crunch instead of tender centers, try our air fryer sweet potato chips.

What to Serve with Air Fryer Sweet Potato Rounds

These pair well with chicken thighs, leg of lamb, short ribs, or turkey. They also work in grain bowls or added to salads while still warm.

For dipping, garlic aioli, chipotle mayo, ranch, or a yogurt-herb sauce all fit well here. If you want chunkier pieces for bowls, see our air fryer sweet potato cubes.

How to Store and Reheat Air Fryer Sweet Potato Rounds

Let the rounds cool completely before storing. Refrigerate in an airtight container for up to 3 to 4 days. If you stack them, place parchment between layers so they do not stick.

To reheat, air fry at 320°F (160°C) for 3 to 5 minutes, flipping once, until warmed through. If you want a little more color, add about 1 minute at 370°F (188°C) at the end.

A skillet over medium heat with a small amount of oil also revives the edges better than the microwave. Leftovers will be softer than fresh, so I think these are best the same day.
