Instructions
- 1
Slice the sweet potatoes: Use a mandoline or sharp knife to cut sweet potatoes into very thin, uniform rounds, about 1/8-inch thick. Thin slices are key for crispiness.
- 2
Soak and dry: Place slices in a bowl of cold water for 15–20 minutes to remove excess starch. Drain and pat completely dry with a clean towel.
- 3
Season the chips: Toss the dry slices with olive oil, salt, and any optional seasonings until each slice is lightly coated.
- 4
Preheat the air fryer: Set to 350°F (175°C). Lightly spray or brush the basket with oil to prevent sticking.
- 5
Air fry in batches: Arrange slices in a single layer without overlapping. Cook for 10–15 minutes, shaking the basket halfway through. Watch closely in the last few minutes to avoid burning; the edges should turn golden brown and crisp.
- 6
Cool and crisp: Transfer chips to a wire rack to cool for 5 minutes. They will firm up as they cool.

Tips
- Uniform thickness matters: Uneven slices cook inconsistently; thin rounds yield the crispiest chips.
- Don’t overcrowd: Air needs to circulate around each slice to achieve crispness. Cook in batches if necessary.
- Adjust seasoning after cooking: A light sprinkle of salt after frying can enhance flavor without drawing moisture back into the chips.
- Oil choice: Olive oil works well, but avocado or grapeseed oil can give a higher smoke point for extra crispy edges.
Variations / Substitutions
- Sweet potato alternatives: Use purple or Japanese sweet potatoes for a unique color and flavor twist.
- Seasoning swaps: Try cinnamon sugar for a sweet version, or curry powder for a savory twist.
- Dipping sauces: Pair with a garlic aioli, sriracha mayo, or even a classic ketchup.
FAQ
Can I make these ahead of time?
Yes, you can slice and soak sweet potatoes a few hours in advance. Keep them in cold water in the fridge to prevent browning. Fry them just before serving for maximum crispiness.
How do I store leftovers?
Store cooled chips in an airtight container at room temperature for up to 2 days. Reheat in the air fryer at 300°F for 2–3 minutes to refresh crispness.
Can I freeze them?
Air-fried chips don’t freeze well once cooked because they lose crispiness. You can, however, slice and freeze raw sweet potatoes, then air fry from frozen, adding a few extra minutes to the cooking time.
What if my chips are soggy?
Soggy chips usually mean slices were too thick, crowded, or not dried well. Next time, slice thinner, dry thoroughly, and air fry in single layers.
Can I use other oils or sprays?
Yes, avocado, sunflower, or grapeseed oils all work. Lightly spray the basket to prevent sticking and brush the slices lightly to avoid excess oil.
