How to Make Sweet Potato Chips in an Air Fryer

Sweet potato chips are a delicious and healthier alternative to traditional crisps. Air frying them significantly reduces the amount of oil needed while still achieving that desirable crunch. If you’re looking for a tasty snack that’s easy to prepare, look no further! This guide will walk you through the steps to make perfectly crispy sweet potato chips in your air fryer.

Ingredients

To get started, you’ll need the following ingredients:

  • 2 medium-sized sweet potatoes
  • 1-2 tablespoons of olive oil (or your preferred cooking oil)
  • Salt, to taste
  • Optional seasonings: paprika, garlic powder, cayenne pepper, or any herbs you favour

Equipment

  • An air fryer
  • A sharp knife or mandoline slicer
  • A large bowl
  • A clean kitchen towel or paper towel
  • A baking tray (if necessary)

Preparation Steps

1. Selecting Your Sweet Potatoes

Choose firm, unblemished sweet potatoes for the best results. The size is not crucial, but uniformity will help them cook evenly.

2. Slicing the Sweet Potatoes

Wash the sweet potatoes thoroughly to remove any dirt. You can peel them if you prefer, but keeping the skin adds extra nutrients and flavour. Using a sharp knife or a mandoline slicer, cut the sweet potatoes into thin, even slices — ideally around 2-3 mm thick. Thinner slices will yield crisper chips, while thicker slices will be chewier.

3. Soaking the Slices (Optional)

To achieve even crispier chips, soak the sweet potato slices in cold water for about 30 minutes. This step helps to remove excess starch, which can prevent them from crisping up properly. After soaking, drain the slices and pat them dry with a kitchen towel to remove excess moisture.

4. Seasoning

In a large bowl, toss the sweet potato slices with olive oil and your choice of seasonings. Ensure each slice is well-coated, as this will contribute to their crispiness and flavour. Start with a pinch of salt, and feel free to explore other spices according to your taste preferences.

5. Preheating the Air Fryer

Preheat your air fryer to 180°C (350°F) for about 5 minutes. Preheating helps in obtaining the desired crispiness once you start frying the chips.

6. Cooking the Chips

Once preheated, arrange the sweet potato slices in a single layer inside the air fryer basket. Avoid overcrowding, as this can lead to uneven cooking. You may need to cook in batches depending on the size of your air fryer.

Cook the chips for 10-15 minutes, shaking the basket halfway through to ensure even cooking. Keep an eye on them, as cooking times may vary based on the air fryer model and the thickness of your slices. The chips are ready when they are golden brown and crispy.

7. Cooling and Serving

Once cooked, remove the sweet potato chips from the air fryer and let them cool on a plate or a baking tray. This cooling period helps them firm up a bit more. Season with additional salt if needed and serve them warm for the best taste!

Storing Leftovers

If you happen to have any leftover chips (which is unlikely!), you can store them in an airtight container at room temperature for up to three days. For the best texture, it’s recommended to consume them straight away.

Final Thoughts

Making sweet potato chips in an air fryer is a straightforward and enjoyable process. Not only do they serve as a healthy snack, but they can also complement a variety of dishes as a delightful side. With a little experimentation with spices and seasonings, you can create your own unique flavour combinations.

Enjoy your homemade sweet potato chips — guilt-free munching at its finest!
