Whenever I’m craving something warm, crispy, and just a little bit sweet, I find myself reaching for a sweet potato. There’s something deeply comforting about the caramelized edges and creamy center of a perfectly cooked sweet potato slice. And since I discovered how easy they are to make in the air fryer, I honestly haven’t looked back. It’s fast, it’s healthier than deep frying, and it brings out all that natural sweetness in the most delicious way.
These air fryer sweet potato slices have become one of my favorite go-to side dishes and snacks. They’re naturally gluten-free, full of fiber and flavor, and ridiculously easy to customize with whatever spices I’m in the mood for. Whether I’m pairing them with grilled chicken, tossing them into a bowl with avocado and black beans, or munching on them with a creamy dip, they always hit the spot.
What You Need To Make This Recipe
Sweet Potatoes:
Choose medium-sized sweet potatoes with smooth skin and no bruises. I prefer the orange-fleshed varieties like Garnet or Jewel for their creamy texture and naturally sweet flavor. These roast up beautifully in the air fryer, giving you those crispy edges and soft insides we all love.
Olive Oil:
A light coating of olive oil helps the slices crisp up in the air fryer and enhances that rich, roasted flavor. You only need a small amount—too much will make them soggy.
Salt:
Salt is essential to bring out the flavor of the sweet potatoes. I recommend using sea salt or kosher salt for a cleaner, more pronounced taste.
Garlic Powder:
Garlic powder adds a savory punch without overpowering the natural sweetness of the potato. It’s subtle but makes a big difference.
Smoked Paprika:
This is my secret weapon for a slightly smoky depth. It adds beautiful color and just enough complexity to keep things interesting. You can use regular paprika too, but smoked takes it to the next level.
Ingredients List
- 2 medium sweet potatoes
- 1 ½ tablespoons olive oil
- ½ teaspoon salt
- ½ teaspoon garlic powder
- ½ teaspoon smoked paprika
How to Make Air Fryer Sweet Potato Slices
Step 1: Wash and Slice the Sweet Potatoes
Start by scrubbing your sweet potatoes under cool water. You can peel them if you want a smoother texture, but I like to leave the skin on for added fiber and crispiness. Slice them into even rounds, about ¼ inch thick. Try to keep them uniform so they cook evenly.
Step 2: Season the Slices
In a large bowl, toss the sweet potato slices with olive oil, salt, garlic powder, and smoked paprika. Make sure each slice is evenly coated—this is what gives you those irresistible golden edges.
Step 3: Preheat the Air Fryer
Preheat your air fryer to 375°F (190°C) for about 3 minutes. This step ensures the sweet potatoes start cooking right away and helps them get nice and crispy.
Step 4: Arrange in a Single Layer
Lay the slices in a single layer in the air fryer basket. Depending on the size of your air fryer, you may need to do this in batches. Avoid overcrowding or stacking them—they need space for air circulation to crisp up properly.
Step 5: Air Fry to Perfection
Cook the slices at 375°F for 10–12 minutes, flipping them halfway through. Keep an eye on them after the 10-minute mark; you want them browned and slightly crisp on the edges, but still soft in the center.
Tips for Making This Recipe
- Uniform slicing matters. Thinner slices will crisp more like chips, thicker ones will stay soft inside—choose your texture!
- Don’t overcrowd the basket. Airflow is key to getting that golden finish.
- Try other spices. Cinnamon and cayenne for sweet-heat, or Italian herbs for something more savory.
- Leftovers? Reheat them in the air fryer for 2–3 minutes to bring back that crisp texture.
- Want extra crisp? Soak the slices in cold water for 30 minutes before cooking to remove excess starch, then pat dry thoroughly.
FAQs
Can I make these ahead of time?
Yes! You can slice and season them ahead, then refrigerate until ready to air fry. They taste best fresh but reheat beautifully.
Do I need to peel the sweet potatoes?
Not at all. The skin adds texture and nutrients. Just make sure to wash them well.
Can I bake them instead of air frying?
Absolutely. Bake at 400°F on a parchment-lined sheet for 20–25 minutes, flipping halfway.
How thin should I slice the sweet potatoes?
Around ¼ inch is ideal for a soft inside and crisp edge. Thinner slices will cook faster and be more chip-like.
Can I use another oil?
Yes, avocado oil or grapeseed oil works great too—they’re both good for high heat.
