Ingredients for Air Fryer Potato Chips
You only need two ingredients to make these homemade potato chips.
- 1 potato: Use a mandoline to cut the potato into thin, even slices so they cook as evenly as possible.
- Sea salt: Sprinkle over the finished chips for a simple, salty flavor.
You’ll also need cold water for soaking the potato slices.
How to Make Oil-Free Air Fryer Potato Chips
1. Thinly Slice the Potato
Wash the potato and slice it into thin, even rounds using a mandoline. Consistent thickness helps the slices cook more evenly.
2. Soak the Potato Slices
Place the potato slices in a bowl of cold water and soak for about 5 minutes. Drain the water and pat the slices dry with a clean towel.
3. Arrange the Slices on Air Fryer Racks
Arrange the potato slices in a single layer on the air fryer racks. Avoid overlapping the slices so they have room to cook and crisp.
4. Air Fry Until Golden and Crispy
Set the air fryer to 325°F and cook for approximately 20 minutes, flipping the potato slices halfway through cooking.
The exact cooking time can vary depending on the thickness of the slices and your air fryer. Check the chips as they cook and remove them when they are golden and crispy.
5. Add Sea Salt and Serve
Transfer the finished potato chips to a bowl and sprinkle with sea salt. Let them cool briefly, then enjoy your crunchy homemade snack!
Tips for Crispy Air Fryer Potato Chips
- Slice evenly. A mandoline makes it easier to cut thin, consistent potato slices.
- Don’t skip the water soak. Soaking the slices for about 5 minutes helps remove some surface starch.
- Dry the potatoes well. Excess moisture can prevent the slices from crisping properly.
- Arrange in a single layer. Overlapping slices can cook unevenly.
- Flip halfway through. Turning the slices helps them cook more evenly.
- Watch the final minutes. Thin potato slices can go from golden to overdone quickly, so check them toward the end of cooking.
