Tips from the EatingWell Test Kitchen

These are the key tips we learned while developing and testing this recipe in our Test Kitchen to make sure it works, tastes great and is good for you too!

  • When making chips in the air fryer, pat the potatoes dry as much as possible, so they end up frying instead of steaming.
  • Use a mandoline slicer or a sharp knife to create thin, even chips; otherwise, you'll get some half-burned, half-undercooked chips. Aim for a thickness of between 1/16 and 1/8 inches.
  • Seasoning the chips with salt and pepper not only enhances their flavor but also contributes to a crispier texture.
  • Cook the chips in batches, leaving about an inch of space around each slice. This way, the hot air circulates well. It will also make flipping them easier.

Nutrition Notes

  • Sweet potatoes are high in an antioxidant called beta-carotene. This nutrient is converted to vitamin A in the body, which is essential for immunity, reproductive health and healthy skin. They also have fiber, essential for your digestive system and regularity. Sweet potatoes contain a good amount of potassium, which is helpful for maintaining healthy blood pressure—great for heart health.

Ingredients

Original recipe (1X) yields 8 servings

  • 1 medium sweet potato, (about 8 ounces), sliced into ⅛-inch-thick rounds

  • 1 tablespoon neutral oil, such as canola or avocado

  • ¼ teaspoon sea salt

  • ¼ teaspoon ground pepper

Directions

  1. Place sweet potato slices in a large bowl of cold water; soak for 20 minutes. Drain and pat dry with paper towels.

  2. Return the sweet potatoes to the dried bowl. Add 1 tablespoon oil, ¼ teaspoon salt and ¼ teaspoon pepper; toss gently to coat.

  3. Lightly coat air-fryer basket with cooking spray. Place just enough of the sweet potatoes in the basket to form a single layer. Cook at 350°F until cooked through and crispy, about 15 minutes, flipping and rearranging into a single layer every 5 minutes. Using tongs, carefully remove the chips from the air fryer to a plate. Repeat with the remaining sweet potatoes.

  4. Let the chips cool for 5 minutes; serve immediately or cool completely and store in an airtight plastic container for up to 3 days.

Frequently Asked Questions

  • What should I look for when choosing a sweet potato?

    The potato should be firm and unblemished, and straight instead of curvy. We would opt for medium-sized potatoes so they can be flush with the blade of a mandoline slicer. Plus, we can add more potatoes to the air fryer.

  • How do I know the chips are done cooking?

    Once the chips have browned slightly around the edges, use tongs to transfer them to a plate. They will crisp up a bit more as they cool. If they are firm and crisp, they are done. If not, simply return them to the air fryer. Keep an eye on them, though; they can burn quickly.

  • Can I use this recipe with regular potatoes?

    Absolutely, this method will work with most types of potatoes. However, it's important to note that different potatoes have varying levels of starch and sugar, which can affect their crispness. You may want to avoid air-frying red potatoes, as they contain too much moisture and won't become as crispy as sweet potato chips or white potato chips.

  • What's the best way to store the chips?

    Once the chips have cooled, store them in an airtight container at room temperature for about 3 days.

  • What should I serve with the chips?

    We would serve these chips with just about any sandwich we can think of. We love them with our Best Tuna Salad, Best Egg Salad and Cucumber-Avocado-Tomato Sandwich, and burgers, like our Classic Hamburger and Turkey Burgers with Spinach, Feta & Tzatziki. They're also perfect for snacking on with a dip like our Copycat Trader Joe's Caramelized Onion Dip, Roasted Beet Hummus and Kale Artichoke Dip.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
