These chips come together fast, and they’re easy to customize with your favorite spices. If you’ve got a couple of sweet potatoes and 20 minutes, you’re set.

What Makes This Recipe So Good
- Fast and efficient: The air fryer cooks thin slices in minutes, giving you crisp chips without heating up the whole kitchen.
- Light on oil: A small amount of oil is all you need. The result is lighter chips that still deliver on crunch.
- Big flavor, simple method: Salt, pepper, and a pinch of spices do the heavy lifting.
Sweet potatoes already bring natural sweetness and depth.
- Flexible: Make them savory, spicy, or sweet. They play well with almost any seasoning.
- Great for snacking or sides: Serve as a snack, with dips, or as a crisp side to sandwiches, wraps, and burgers.
Shopping List
- 2 medium sweet potatoes (orange-flesh varieties like Garnet or Jewel work well)
- 1–2 tablespoons olive oil or avocado oil
- 1 teaspoon kosher salt (plus more to taste)
- 1/2 teaspoon black pepper
- 1/2 teaspoon smoked paprika (optional, for depth)
- 1/4 teaspoon garlic powder (optional)
- Pinch of cayenne or chili powder (optional, for heat)
- Optional finishing touches: flaky sea salt, everything bagel seasoning, cinnamon sugar, or ranch seasoning
Step-by-Step Instructions
- Prep the sweet potatoes: Wash and scrub well. You can peel them or leave the skins on for extra texture and nutrients.
Trim the ends.
- Slice thin and even: Use a mandoline on the 1.5–2 mm setting if you have one. If using a knife, aim for very thin, even slices. Uniform thickness is key for chips that cook at the same rate.
- Soak briefly (optional but helpful): Place slices in a bowl of cold water for 10–15 minutes to remove excess starch. This helps them crisp.
Drain and pat very dry with a clean towel. Dry slices = better crunch.
- Season: In a large bowl, toss slices with oil until lightly coated—don’t drench them. Sprinkle in salt, pepper, and any optional spices. Toss again to distribute evenly.
- Preheat the air fryer: Set to 325°F (163°C) for 3 minutes.
A slightly lower temp helps the slices dehydrate and crisp without burning.
- Arrange in a single layer: Place slices in the basket or on the tray in one layer, with minimal overlap. You’ll need to work in batches for best results.
- Air fry, then flip: Cook at 325°F for 8–10 minutes, flipping or shaking the basket halfway. Start checking around minute 7.
They’re done when edges are curled and centers feel firm and dry.
- Finish at a higher temp (if needed): If they’re not quite crisp, bump to 350°F (177°C) for 1–2 more minutes. Watch closely—the line between crisp and burnt is thin.
- Cool on a rack: Transfer chips to a wire rack or paper-towel-lined sheet. They crisp further as they cool. Sprinkle with a pinch of flaky salt while warm.
- Repeat: Continue with remaining batches. If earlier chips soften, pop them back in the air fryer at 300°F (149°C) for 1–2 minutes to refresh.
Keeping It Fresh
Let chips cool completely before storing.
Any trapped steam will soften them fast. Keep in an airtight container at room temperature for up to 3 days. If they lose their crunch, air fry at 300°F for 2–3 minutes to revive.
Avoid the fridge; it adds moisture and makes chips limp.
Why This is Good for You
- Nutrient-dense: Sweet potatoes bring vitamin A (beta-carotene), vitamin C, potassium, and fiber.
- Lower in oil: Air frying uses a fraction of the oil compared to deep-frying, cutting down total fat and calories.
- Stable energy: The natural fiber helps keep you fuller longer, making this a smarter snack than many bagged chips.
- Simple ingredients: No preservatives or hidden sugars—just whole food with a few spices.
Pitfalls to Watch Out For
- Uneven slices: Thick pieces stay chewy while thin ones burn. Use a mandoline if possible.
- Too much oil: Extra oil weighs chips down and prevents crisping. Lightly coat—don’t soak.
- Overcrowding: Stacked slices steam instead of crisp.
Keep to a single layer and batch-cook.
- High heat from the start: Going straight to 400°F can char edges before centers dry out. Start lower, finish higher if needed.
- Skipping the dry step: If you soak the slices, dry them thoroughly. Moisture is the enemy of crunch.
Recipe Variations
- Smoky BBQ: Mix smoked paprika, brown sugar, chili powder, garlic powder, onion powder, salt, and pepper.
Toss lightly before air frying.
- Salt and Vinegar: Soak slices in diluted apple cider vinegar (1 cup water + 1/3 cup vinegar) for 10 minutes, pat dry, then oil and salt. Add a splash of vinegar powder after cooking for extra punch.
- Sweet and Spiced: Toss with a whisper of oil, then cinnamon, a pinch of nutmeg, and a sprinkle of sugar. Finish with a tiny bit of flaky salt to balance.
- Herby Ranch: After cooking, dust with ranch seasoning or a mix of dried dill, parsley, garlic powder, onion powder, and salt.
- Chili-Lime:</-strong> Season with chili powder, cumin, and salt.
Squeeze lime over the chips right before serving.
- Everything Bagel: Sprinkle everything bagel seasoning right when they come out warm so it sticks.
FAQ
Do I need to peel the sweet potatoes?
No. The skin is edible and adds texture and nutrients. Peel if you prefer a more delicate chip, but it’s not required.
How do I get my chips really crispy?
Slice thin and even, don’t overcrowd, and start at 325°F.
Let them cool on a rack to finish crisping. If they’re still soft, a quick reheat at 300°F for a couple of minutes brings back the crunch.
Why are some chips browning too fast?
They’re likely thinner than the rest or your heat is too high. Lower the temperature slightly and check a minute earlier on your next batch.
Rotating the basket halfway also helps.
Can I make these oil-free?
Yes, but they’ll be a touch drier and may not brown as evenly. Skip the oil and season lightly, then watch closely to avoid scorching. Consider a quick spritz of water to help spices stick.
What dips go well with sweet potato chips?
Great options include garlic yogurt dip, chipotle mayo, avocado crema, honey mustard, or a simple sour cream and chive dip.
The natural sweetness pairs well with tangy or smoky flavors.
Can I use white or purple sweet potatoes?
Absolutely. White and purple varieties work well and bring different textures and flavors. Adjust time slightly if they’re denser—check for crispness rather than relying only on the clock.
How thin should I slice them?
Aim for 1.5–2 mm.
Thicker slices can still be tasty but will be more like crisps with a tender center. Consistency is more important than exact thickness.
Can I double the recipe?
Yes, but cook in batches. Keep finished chips on a rack and refresh them for 1–2 minutes at 300°F before serving to ensure everything is crisp and warm.
