Air Fryer Sweet Potato Chips: Quick, Easy, Crispy!

how to cook sweet potato chips in air fryer

Sweet potato chips are a delicious and healthy snack that can be made in an air fryer. They are a great alternative to deep-fried sweet potatoes as they are cooked with less oil, resulting in a lighter and healthier snack with a slight crisp. To make sweet potato chips in an air fryer, you will need to slice the sweet potatoes thinly and evenly, soak them in water to remove the starch, dry them, and then toss them in oil and seasonings. The air fryer should be preheated and the chips should be cooked in batches to ensure even cooking and crispiness. The chips will continue to crisp up as they cool, and they can be stored in an airtight container for later enjoyment.

Choosing the right sweet potatoes

First, look for medium-sized sweet potatoes. This ensures that you can get the ideal fry length. Avoid potatoes that are too long, as you want to be able to use the full length of the potato for your fries. Remember that sweet potatoes shrink after cooking, so aim for a shape that is slightly longer than your desired fry length.

Next, consider the thickness of your fries. For crispier chips, it is recommended to cut the sweet potatoes into thin slices. Aim for a thickness of around 1/4 inch to 1/2 inch. The thinner the slices, the crispier they will be. However, if you prefer thicker chips, feel free to adjust the thickness to your liking, keeping in mind they may not get as crispy.

When selecting sweet potatoes, look for ones that are fresh and firm. Avoid any that have soft spots, bruises, or sprouting ends. The skin should be smooth and tight, and the colour should be vibrant and even. Depending on your preference, you can choose to peel the sweet potatoes or leave the skin on for extra fibre.

It is also important to choose sweet potatoes that are similar in shape and size. This ensures that they cook evenly in the air fryer. Look for potatoes that have a relatively uniform shape to make cutting them into fries easier.

Lastly, opt for sweet potatoes that feel heavy for their size. This indicates that they are moist and have a higher starch content, which can lead to crispier chips.

By following these tips, you'll be sure to choose the right sweet potatoes for making delicious and crispy air-fried sweet potato chips.

Preparing the sweet potatoes

Next, you will want to cut the sweet potatoes into fries. The fries should be cut into even 1/4-inch thick planks, and then into 1/4-inch thick fries. The thinner you cut them, the crispier they will be. However, if you prefer thicker fries, you can cut them up to 1/2-inch thick. Just be aware that thicker fries may require a little longer cooking time. It is also important to ensure that all the fries are cut to the same size so that they cook evenly.

Once you have cut your sweet potatoes, you will need to soak them. Fill a large bowl with hot tap water and submerge the sweet potatoes for 10 minutes. This process helps to remove the additional starch from the potatoes. After 10 minutes, drain the potatoes and pat them dry with a paper towel. Now your sweet potatoes are ready to be tossed in oil and seasoning and placed into the air fryer.

Seasoning the sweet potatoes

Firstly, you'll want to decide whether to peel your sweet potatoes or leave the skin on. Leaving the skin on adds texture and fibre to your chips, but peeling them will give a more uniform look and feel.

Next, you'll want to decide on your seasonings. Sea salt and pepper are a classic combination and will give your chips a salty, savoury kick. If you're feeling adventurous, you could try smoked paprika for a smokey flavour, or cayenne pepper for a spicy kick. Garlic powder, cinnamon, and pumpkin spice are also great options to experiment with. You can also try a combination of spices, such as half chilli powder and half paprika. If you like your chips on the sweeter side, a sprinkle of brown sugar can add a delicious touch.

Once you've selected your seasonings, it's time to toss your sliced sweet potatoes in a bowl with a small amount of oil. You can use olive oil, avocado oil, or any neutral-tasting oil such as canola or vegetable oil. Make sure all the slices are coated in oil, then sprinkle on your chosen seasonings and toss again to ensure an even coating.

Now your sweet potatoes are seasoned, they're ready to be placed in the air fryer!

Cooking the sweet potatoes

To cook sweet potato chips in an air fryer, start by selecting medium-sized sweet potatoes. Peel the sweet potatoes and cut off the skinny ends. You can save these ends for a different recipe. Then, cut the sweet potatoes in half lengthwise. This will make it easier to lay them flat on a cutting board and start cutting them into long slices. The slices should be about 1/4-inch to 1/2-inch thick. The thinner you cut them, the crispier they will be.

Next, you will need to soak the sweet potato slices. Fill a large bowl with hot tap water and submerge the slices, letting them soak for about 10 minutes. This step helps to remove the additional starch from the potatoes. After soaking, drain the potatoes and use paper towels to pat them dry.

Now it's time to season the sweet potato slices. Place the slices in a clean, dry bowl and toss them with a small amount of oil. You can use olive oil or a neutral-tasting oil such as canola oil or avocado oil. Add your desired spices to the bowl and toss everything together to coat the slices evenly. Recommended spices include kosher salt or sea salt, garlic powder, black pepper, and paprika. If you want a smokier flavour, use smoked paprika. For a spicy kick, add some cayenne pepper, or you can even try cinnamon or pumpkin spice for a sweet variation.

Once your sweet potato slices are seasoned, it's time to cook them in the air fryer. Preheat your air fryer if necessary (check your specific air fryer's instructions). Lightly coat the air fryer basket with cooking spray or oil. Place the sweet potato slices in a single layer in the basket, making sure they are not overcrowded so that they can get crispy. Set the air fryer to 350 degrees Fahrenheit and cook for about 8-12 minutes, shaking the basket halfway through the cooking time. The chips are done when they are golden brown and crisp.

Remove the cooked chips from the air fryer using tongs and place them on a plate or a cooling rack. Repeat the above steps with the remaining sweet potato slices. Let the chips cool for about 5 minutes before serving. Enjoy your delicious, crispy, and healthy sweet potato chips!

Storing the sweet potatoes

Storing sweet potatoes is a great way to make the most of your haul. Sweet potatoes are a sturdy root vegetable and are, therefore, relatively easy to store.

The U.S. Sweet Potato Council recommends storing sweet potatoes in a cool, dry area with good ventilation. If you plan to eat them within a month, it is best to avoid storing them in the fridge, as refrigeration can affect their taste and texture. However, if you want them to last longer than a month, you can refrigerate them, but be aware that they may develop an unpleasant taste and a hard center.

Once cooked, sweet potato chips should be stored in a plastic ziplock bag or airtight container. They can be kept in a pantry or on a counter for up to 2 weeks. If you have cooked more sweet potatoes than you can consume within 2 hours, it is best to refrigerate them to prevent bacteria growth and the risk of foodborne illness. In the refrigerator, they will stay good for about 5 days.

If you want to store sweet potatoes for an even longer period, you can freeze them. There are several ways to do this:

  • Boil or bake the sweet potatoes until tender, then mash them without adding any dairy products. Add a bit of lemon juice to prevent the mash from turning brown. Allow the mash to cool completely, then transfer it to dated freezer bags.
  • Alternatively, you can freeze cooked sweet potatoes whole or sliced. To do this, scrub the sweet potatoes, pierce them in a few places, and bake them at 425 degrees Fahrenheit for about an hour. Once they have cooled to room temperature, wrap them individually in foil and place them in dated freezer bags. Frozen sweet potatoes, whether whole, sliced, or mashed, will last in the freezer for about a year.
