Ingredients for air fried sweet potato chips
Three core ingredients plus optional seasonings create ultra-crispy sweet potato chips in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Sweet Potatoes 🍠 | 2 large | Organic preferred, peeled |
| Avocado Oil 🫒 | ¼ cup | High smoke point for crispiness |
| Sea Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Smoked Paprika 🌶️ | 1 tsp | Optional for smoky flavor |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly ground for best flavor |
| Garlic Powder 🧄 | ½ tsp | For subtle savory depth |
The sweet potatoes are non-negotiable—Beauregard variety is ideal for its natural sweetness and starchy texture. Trader Joe's and Whole Foods carry organic options year-round, but any firm sweet potato works. Look for ones with smooth, unblemished skin—they slice more evenly. Peeled and dried thoroughly before air frying is critical for crispiness. I always test for doneness with the toothpick method, though these chips crisp up faster than oven-baked varieties.
Avocado oil's high smoke point makes it perfect for air frying—Mazola or Primal Kitchen are my go-tos, but any neutral oil with a smoke point over 400°F works. No oil? Olive oil spray in a pinch, though flavor may vary slightly. The seasonings are completely optional but recommended. Smoked paprika adds depth, while garlic powder and black pepper create a subtle savory profile. For spicy chips, swap in cayenne or chili powder at half the amount—just remember these are vegan-friendly and ready in minutes.
Store the cooled chips in an airtight container with a paper towel layer to prevent sogginess. They'll stay crisp for 5 days at room temperature or 1 month frozen in a sealed bag. Re-crisp frozen chips at 350°F for 3-5 minutes. For meal prep, divide into single-serving bags—perfect for lunchboxes or quick snacks. The key to reheating is low and slow to restore crispiness without burning.

Step-by-step instructions for air fried sweet potato chips
Here's how to achieve perfectly crispy sweet potato chips every time—no oil splatter, no soggy results.
Prepare the Sweet Potatoes for Even Cooking
Start by peeling the 2 large sweet potatoes completely—even a small amount of skin can prevent even cooking. Using a sharp mandoline slicer, cut them into ⅛-inch thick slices (about 1/8th of an inch). The thinner the slices, the crispier the chips will become, but don't go thinner than ⅛ inch or they'll burn before cooking through.
Arrange the slices on a clean kitchen towel and pat them dry thoroughly with another towel. Any moisture left on the slices will prevent the oil from adhering properly, leading to uneven crispiness. I like to work in batches—lay out the slices in a single layer so they don't stick together. This drying step is non-negotiable for achieving that perfect crunch.
Season the Sweet Potato Slices
In a small bowl, combine 1.5 teaspoons sea salt, 1 teaspoon smoked paprika, 0.5 teaspoon ground black pepper, and 0.5 teaspoon garlic powder. I use fine-grain sea salt for even distribution, and I always shake the spices together before adding them to the bowl to ensure a consistent blend.
Toss the dried sweet potato slices in the spice mixture until they're evenly coated. You'll want to handle them gently—too much agitation can bruise the edges and make them cook unevenly. For best results, I like to do this in two batches if I have a large air fryer. The spices should cling to the slices without forming clumps. This seasoning creates the perfect balance of smoky, savory, and slightly sweet flavors that complement the natural sweetness of the potatoes.
Preheat the Air Fryer for Optimal Crispiness
Preheat your air fryer to 375°F for 5 minutes. This step is crucial—air fryers work best when preheated, as it ensures the oil is hot enough to create that signature crispy texture right from the start. Most air fryers have a preheat function, but if yours doesn't, simply run it empty for 5 minutes before adding the chips.
While the air fryer preheats, lightly toss the seasoned sweet potato slices in 0.25 cup avocado oil. I use avocado oil because of its high smoke point—it won't break down under the heat and will give you that beautiful golden-brown finish. Toss the slices gently so they're lightly coated but not drenched in oil. The oil should look like it's just barely clinging to the surfaces. This light coating is all you need for crispy chips without excess grease.
Air Fry in Batches for Even Cooking
Working in batches (don't overcrowd the basket), place the oiled sweet potato slices in a single layer in the air fryer basket. Leave at least ½ inch of space between each slice—this allows hot air to circulate freely and ensures even cooking. If you're using a large air fryer, you can fit about 20-25 slices per batch, depending on the model.
Air fry at 375°F for 12-15 minutes, shaking the basket every 4-5 minutes to prevent sticking and promote even browning. You'll know they're done when the edges are deep golden brown and the slices are crispy to the touch. The center should still have a slight give—if it's completely hard, they're overdone. This is where patience pays off; slightly undercooked chips in the center will crisp up as they cool.
Cool and Serve Immediately
Remove the crispy sweet potato chips from the air fryer and transfer them immediately to a wire rack set over a baking sheet. This step is key—letting them cool on a rack prevents them from steaming and becoming soggy. Allow them to cool for 5-7 minutes before serving. The chips will continue to crisp up as they cool, and this resting period also helps the flavors meld together.
Serve the chips warm for the best texture—crispy on the outside with a tender, slightly sweet interior. If you're serving them as an appetizer, arrange them on a platter and sprinkle with an extra pinch of sea salt for a finishing touch. These chips pair perfectly with dips like spicy mayo, sour cream, or even a simple honey mustard for a sweet and tangy contrast. Enjoy them while they're still crispy—once they cool completely, they'll soften slightly.
Pro Tips For Making Air Fried Sweet Potato Chips
- CUT THIN, CUT EQUAL: Use a sharp mandoline or knife to slice sweet potatoes 1/16-inch thick—no thicker, no thinner. I learned this the hard way when my first batch came out chewy in the middle because I eyeballed it. A ruler or stack of business cards as a guide works if you don’t own a mandoline.
- DRY THE SLICES: Pat each slice with a paper towel before air frying. Wet chips steam instead of crisp, and you’ll end up with sad, limp results. This takes 30 seconds but guarantees that perfect crunch you’re after—trust me, it’s worth it.
- SHAKING IS NON-NEGOTIABLE: Every 3-4 minutes, shake the basket or flip the chips with tongs. The air fryer’s hot spots mean one side will burn if left alone. I used to forget, and half my batch would turn into charcoal while the rest stayed doughy.
- SALT AFTER CRISPING: Spritz with avocado oil, then air fry until golden (about 12-15 minutes at 375°F). Then season with salt, smoked paprika, and black pepper—this locks in flavor and prevents sogginess. Seasoning too early just makes them taste bland by the end.
Common mistakes when making this recipe
Skipping the Drying Step
One of the biggest mistakes is rushing through the drying process after slicing. Sweet potatoes contain a lot of natural moisture, and even a damp surface will prevent the oil from adhering properly. I’ve seen people skip this step entirely, leading to soggy, uneven chips.
Always pat your slices thoroughly with paper towels and let them air-dry on a rack for at least 5 minutes before seasoning. This ensures the oil clings to the surface for that perfect crisp. 🌡️
Overcrowding the Basket
Packing too many slices into the air fryer basket at once is a recipe for disaster. Overcrowding traps steam and prevents hot air from circulating properly, resulting in uneven cooking and limp chips. I recommend working in batches, leaving at least ½ inch of space between each slice.
If your air fryer is full, reduce the batch size or cook in two rounds. This might add a few extra minutes, but it guarantees consistent crispiness throughout. 🍠
Using the Wrong Oil
Not all oils are created equal when it comes to air frying. Using low-smoke-point oils like olive oil can cause the chips to taste bitter or even smoke excessively. I always use avocado oil or vegetable oil with a smoke point over 400°F.
These oils maintain their integrity under high heat and create that golden, crispy finish. If you’re in a pinch, a light spray of olive oil can work, but expect slightly less crispiness. 🫒
Ignoring the Preheat
Skipping the preheat step is a common oversight that can lead to uneven cooking and longer cook times. Air fryers need to reach the optimal temperature before adding food, just like ovens. Always preheat your air fryer to 375°F for 5 minutes before adding the chips.
This ensures the oil is hot enough to create that signature crisp right from the start. Trust me, this small step makes a huge difference in texture. ⏱️
Overcooking for Extra Crispiness
I’ve seen people leave sweet potato chips in the air fryer for too long, thinking it will make them extra crispy. However, overcooking turns the edges burnt while the center remains undercooked or rubbery. The goal is deep golden brown edges with a slight give in the center.
Remove the chips when they’re crispy to the touch and let them cool—they’ll continue to crisp up as they rest. Overcooking is a fast track to disappointment. 🔥
Not Shaking the Basket
Forgetting to shake the basket during cooking can lead to uneven browning and stuck slices. Sweet potato chips need to be moved around every 4-5 minutes to ensure all sides get exposed to the hot air.
I like to use a silicone spatula to gently lift and flip the slices, making sure none stick to the basket. This simple step ensures every chip comes out perfectly crispy and golden. 💫

Frequently asked questions
Can I use regular potatoes instead of sweet potatoes?
While you can technically use regular potatoes, they won't give the same delicious results. Sweet potatoes have a naturally sweet, starchy texture that creates that perfect balance of flavor and crispiness. Regular potatoes tend to be less sweet and more floury, which can lead to a denser, less crispy chip. Stick with sweet potatoes for the best texture and taste!
How do I make these chips spicier?
For extra heat, add ½ teaspoon cayenne pepper or 1 teaspoon chili powder to your seasoning mix. You can also sprinkle a pinch of cayenne over the chips right after air frying for a quick kick. For a smoky-spicy combo, try ½ teaspoon smoked paprika + ¼ teaspoon cayenne. Just remember—start with less if you're sensitive to spice!
Why are my chips not crispy?
Uneven crispiness usually comes from one of three issues: not drying the slices properly, overcrowding the air fryer, or using the wrong oil. Always pat slices completely dry before seasoning, leave space between chips in the basket, and use a high-smoke-point oil like avocado oil. Thin slices (⅛ inch) also crisp better than thicker ones.
Can I make these chips ahead of time?
Let the chips cool completely, then store them in an airtight container with a paper towel layer to absorb moisture. They'll stay crisp for 5 days at room temperature or 1 month in the freezer. To restore crispiness, air fry frozen chips at 350°F for 3-5 minutes. For best texture, enjoy them fresh, but prepping ahead makes them perfect for meal prep.
What's the best way to serve these chips?
These chips are fantastic as a standalone snack, but they also make great toppings! Try them on salads for crunch, sprinkled over soups, or as a topping for tacos. For dipping, pair them with spicy mayo, sour cream, or honey mustard. Warm chips pair best with creamy dips, while cooled chips work well with tangy options. Don't forget the classic—just a sprinkle of extra salt!
