Air Fryer Potato Chips

Air fryer potato chips are my go-to snack when I want something crunchy without heating up the whole kitchen. I started making these on lazy Sunday afternoons and honestly, I haven’t bought a bag from the store since.

Just one russet potato, a quick spritz of olive oil, salt, and pepper. That’s all it takes to get chips that are thin, crispy, and way more satisfying than anything from a bag. The air fryer does most of the work, and you get that satisfying crunch in about 15 minutes flat. These are great on their own, alongside a dip, or just as something to munch on while you scroll through your phone.

Ingredients

• 1 russet potato (about 350g), washed and scrubbed
• Olive oil cooking spray
• ½ teaspoon salt
• Ground black pepper, to taste

How To Make Air Fryer Potato Chips

1. Slice the potato thin. Using a mandoline or a very sharp knife, slice the russet potato into rounds about 1–2mm thick. The thinner and more uniform, the crispier they’ll get.
2. Soak the slices. Place the potato slices in a bowl of cold water and soak for 20–30 minutes. This removes excess starch and helps them crisp up instead of turning soggy.
3. Dry thoroughly. Drain the slices and spread them out on a clean kitchen towel or paper towels. Pat dry as well as you can. Any moisture left will steam instead of crisp.
4. Season the slices. Lay the dried slices in a single layer and spray both sides lightly with olive oil cooking spray. Sprinkle evenly with ½ teaspoon salt and a few cracks of ground black pepper.
5. Load the air fryer. Arrange the potato slices in a single layer in the air fryer basket. Don’t overlap them. Work in batches if needed.
6. Air fry at 350°F (175°C) for 12–15 minutes. Flip the chips halfway through. Start checking at the 10-minute mark since thickness and air fryer models vary. You’re looking for golden edges and a dry, matte surface.
7. Watch the final 2 minutes closely. Chips go from golden to burnt fast. Pull them out the moment they look crispy, they’ll firm up even more as they cool.
8. Cool on a wire rack. Transfer chips to a wire rack and let them cool for 3–5 minutes before eating. They’ll crisp up fully as they sit.

Why Soaking the Potato Actually Matters

A lot of people skip the soaking step and then wonder why their air fryer potato chips turned out chewy in the middle. The starch on the surface of freshly sliced potatoes is the culprit. When heat hits it, that starch turns gummy before the chip has time to properly dry out.

Twenty to thirty minutes in cold water makes a real difference. You’ll actually see the water turn cloudy from the starch releasing. After soaking, drying the slices completely is just as important. I usually go through at least two paper towels per batch.

Getting the Slice Thickness Right

This is probably the single thing that makes or breaks homemade air fryer potato chips. If your slices are too thick, they stay leathery. Too thin and they burn before they fully dry out. The sweet spot is right around 1–2mm, which is the thinnest setting on most mandolines.

If you don’t own a mandoline, a sharp chef’s knife works, but you’ll need to go slowly and keep your slices consistent. Uneven slices mean some chips are perfect while others are either underdone or scorched. It’s worth the extra minute of careful slicing.

Seasoning Ideas Beyond Salt and Pepper

Plain salt and pepper is a solid starting point, but these chips take on other flavors really well. Once the chips come out of the air fryer, sprinkle while they’re still warm so the seasoning sticks. A few ideas worth trying: smoked paprika, garlic powder, onion powder, a pinch of cayenne for heat, or nutritional yeast for a cheesy flavor without the cheese.

You can also go sweeter with cinnamon and a tiny bit of sugar, which sounds odd but works surprisingly well with russet potato. Just keep the add-ons light since the chips are already delicate once cooked. Heavy wet seasoning like sauces should be served on the side for dipping rather than tossed on the chips directly.

Batch Cooking and Keeping Them Crispy

The hardest part about air fryer potato chips is that one potato doesn’t make a huge amount, and the temptation to cram too many into the basket is real. Resist it. A single layer is non-negotiable if you want even, crispy results. Overlapping slices just steam each other.

For a bigger batch, cook in rounds and let each batch cool completely on a wire rack before stacking or storing. If chips sit in a pile while still warm, condensation builds up and they go soft. They keep well in an airtight container at room temperature for 2–3 days, though honestly in my house they rarely last past day one.

Quick Tips

• A mandoline slicer gives the most even results; use the cut-resistant glove that came with it.
• Don’t skip soaking. Even 15 minutes helps if you’re short on time.
• Every air fryer runs a little differently. Start checking your chips at 10 minutes.
• Salt right after cooking while the chips are still warm for better seasoning adhesion.
• One large russet potato makes about 2 small servings. Double up if you’re feeding more than one person.
• Chips with any moisture left will go soft quickly, so make sure they’re bone dry before they go in the basket.
• You can prep and soak the slices up to an hour ahead, just keep them submerged in cold water in the fridge until you’re ready to cook.

Recipe FAQs

Why are my air fryer potato chips coming out soft instead of crispy? The most common reason is moisture. Either the slices weren’t dried thoroughly after soaking, or the basket was too crowded and the chips steamed instead of crisped. Try patting the slices dry more aggressively and cooking in smaller batches in a single layer.

Can I make these without olive oil spray? You can, but the chips won’t brown as evenly and may come out a bit pale in spots. A very light coat of any neutral cooking spray works fine. Olive oil spray adds a subtle richness that plays well with the salt, so it’s worth keeping it in.

What’s the best potato variety for air fryer chips? Russet potatoes work best because of their low moisture content and high starch, which crisps up well in dry heat. Waxy potatoes like red or Yukon Gold hold more water and are harder to get fully crispy without burning the edges first.

Can I use an oven instead of an air fryer? Yes, bake at 375°F (190°C) on a parchment-lined baking sheet for about 20–25 minutes, flipping halfway. The result is slightly less even than the air fryer but still very good. Check out this Tater Tot Casserole if you’re in the mood for more potato-based comfort food from the oven.

How do I store leftover chips? Let them cool completely, then transfer to an airtight container or zip bag at room temperature. They stay crispy for 2–3 days. Avoid the fridge as the moisture will make them go soft.
