If you’re a fan of sweet potatoes but tired of baking them whole or boiling them into mush, this air fryer method is about to become your new favorite. Sweet potato slices made in the air fryer are crispy on the outside, tender on the inside, and require almost no oil—making them a guilt-free treat. Whether you’re meal prepping, feeding a family, or just craving something warm and satisfying, this recipe checks all the boxes.
The beauty of using an air fryer lies in its ability to mimic deep-frying without the grease.

No more waiting 45 minutes for a baked sweet potato to soften. With this method, you’ll have perfectly cooked slices in under 20 minutes. And cleanup? Just a quick wipe of the basket—no greasy pans or splattered oil.
What You’ll Need
This recipe keeps things simple with just a few basic ingredients you likely already have in your kitchen. No fancy gadgets or hard-to-find spices required.
Ingredients
- 2 medium sweet potatoes (about 1 lb total)
- 1 tablespoon olive oil (optional, for extra crispiness)
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ½ teaspoon smoked paprika (or regular paprika)
- Optional: ¼ teaspoon garlic powder, pinch of cayenne for heat
Equipment
- Air fryer (any model works—basket or tray style)
- Sharp knife or mandoline slicer
- Mixing bowl
- Tongs or fork for flipping
Step-by-Step Instructions
Follow these easy steps for perfectly cooked sweet potato slices every time.
1. Prep the Sweet Potatoes
Start by washing the sweet potatoes thoroughly under cool water. You can peel them if you prefer, but leaving the skin on adds extra fiber and nutrients—plus, it gets nice and crispy in the air fryer. Pat them completely dry with a clean towel.
Using a sharp knife or a mandoline slicer, cut the sweet potatoes into even ¼-inch thick rounds. Uniform thickness is key here—if some slices are thicker than others, they won’t cook evenly. Thinner slices will crisp up faster, while thicker ones stay softer in the center. For a balance of crisp and tender, ¼-inch is ideal.
2. Season the Slices
Place the sweet potato rounds in a mixing bowl. Drizzle with olive oil if using—this helps promote browning and crispiness. Toss gently to coat evenly. Then sprinkle with salt, pepper, paprika, and any optional seasonings. Toss again until all slices are lightly seasoned.
Don’t skip the oil entirely if you want maximum crispness, but even without it, the natural sugars in sweet potatoes will caramelize beautifully in the air fryer.
3. Air Fry to Perfection
Preheat your air fryer to 400°F (200°C) for 3–5 minutes if your model allows it. While not always necessary, preheating ensures consistent cooking from the start.
Arrange the sweet potato slices in a single layer in the air fryer basket. Avoid overlapping—crowding prevents proper airflow and leads to steaming instead of crisping. Depending on your air fryer size, you may need to cook in batches.
Air fry for 12–15 minutes, flipping the slices halfway through. Cooking time may vary slightly based on thickness and your specific air fryer model. Check at the 10-minute mark if you’re unsure. The slices are done when they’re golden brown around the edges and fork-tender in the center.
4. Serve and Enjoy
Once done, carefully remove the slices using tongs or a fork—they’ll be hot! Let them cool for a minute or two before serving. They’re delicious on their own, but feel free to get creative.
Serving Suggestions and Variations
These sweet potato slices are incredibly versatile. Here are a few ways to enjoy them:
As a Side Dish
Pair them with grilled chicken, roasted salmon, or a hearty salad. Their natural sweetness complements savory mains beautifully. Try them alongside our Coho Salmon Air Fryer Recipe for a balanced, flavorful meal.

Flavor Variations
Want to switch things up? Here are a few tasty twists:

- Sweet & Smoky: Use smoked paprika and a touch of cinnamon for a unique flavor profile.
- Vegan & Oil-Free: Skip the oil entirely and rely on the air fryer’s dry heat—still delicious!
Tips for Best Results
Want restaurant-quality sweet potato slices every time? Keep these pro tips in mind:
Slice Evenly
Use a mandoline slicer for consistent thickness. Uneven slices lead to some burning while others remain undercooked.
Don’t Overcrowd the Basket
Leave space between slices so hot air can circulate. If needed, cook in batches. Rushing this step leads to soggy results.
Flip Halfway Through
This ensures both sides crisp up evenly. Set a timer so you don’t forget!
Adjust Time Based on Thickness
Thinner slices (⅛-inch) may only need 10 minutes, while thicker ones (½-inch) could take up to 18 minutes. Always check for doneness.
Let Them Rest
After air frying, let the slices sit for 1–2 minutes. This helps them firm up slightly and makes them easier to handle.
Frequently Asked Questions
We’ve covered the basics, but you might still have a few questions. Here’s what others are asking:
Can I make these without oil?
Yes! While a light coating of oil enhances crispiness, you can skip it entirely. The sweet potatoes will still caramelize and develop a nice texture in the air fryer.
How do I store leftovers?
Store cooled slices in an airtight container in the fridge for up to 4 days. Reheat in the air fryer at 375°F for 3–5 minutes to restore crispness.
Can I freeze sweet potato slices?
Absolutely. After cooking, let them cool completely, then freeze in a single layer on a baking sheet. Once frozen, transfer to a freezer bag. Reheat directly in the air fryer—no thawing needed.
Why are my slices soggy?
This usually happens when the basket is overcrowded or the slices are too thick. Ensure proper spacing and flip them halfway through cooking.
Can I use white potatoes instead?
Yes, but the flavor and texture will differ. White potatoes won’t have the same natural sweetness, but they’ll still crisp up nicely. Try our Air Fryer Potato Wedges Recipes for a classic alternative.
How long do sweet potatoes last in the air fryer?
For best texture, eat them within 2 hours of cooking. Reheating in the air fryer (not the microwave) helps maintain crispness.

Frequently Asked Questions
Can I make sweet potato slices in advance?
Yes, you can prep and slice the sweet potatoes up to 24 hours ahead. Store them in cold water in the fridge to prevent browning, then pat dry and season before air frying.
What’s the best way to reheat air-fried sweet potato slices?
Reheat in the air fryer at 375°F for 3–5 minutes until warm and crispy. Avoid the microwave, as it can make them soggy.
Are air-fried sweet potato slices healthy?
Yes! They’re lower in fat than fried versions and retain most of their nutrients, including fiber, vitamin A, and potassium.
Can I use frozen sweet potato slices?
We recommend using fresh slices for best texture. Frozen ones may release too much moisture and become mushy during air frying.

Preheating isn’t always required, but it helps ensure even cooking and better crispiness, especially for dense vegetables like sweet potatoes.
Can I double this recipe?
Yes, but cook in batches to avoid overcrowding the air fryer basket. Doubling the ingredients won’t affect cooking time as long as slices aren’t stacked.
