– The air fryer has a basket within which the fries would be placed. Ensure that you keep the basket greased with any cooking spray of your choice. The cooking spray should however be a kind that wouldn’t stick to your fries. Examples of such include sprays made from oily avocado bases.

Get about two sweet potatoes with slender bodies

The potatoes should not be too long though. That way, you wouldn’t have to bother about reducing the length of the strips after cutting. However, you must take note of the fact that the strips would still shrink after they have been cooked. So, the lengths you work with must be slightly more than the usual length for potato fries.

Peel the skin off the potatoes

Most people would prefer to leave the skins though, for purposes tied to nutritional value. If you are going to do that, ensure that you wash the skins thoroughly under a flow of warm water in order to get rid of germs and other specks of dirt.

Place the potatoes on a chopping board and then, cut them longitudinally (along their lengths).

The first slice should divide the potatoes into halves. The second slice should lead to the formation of potato strips. Ensure that the strips are cut thinly enough. The thinner they are, the crispier they’ll turn out to be. The fatter the strips are, the more of potato wedges they’d taste like.

Preheat your air-fryer to any temperature of your choice

Usually, a temperature of 140-degree Fahrenheit does the trick.

Now, it’s time to work on the seasoning for your fries! This step is what fetches you the sweetness! There are so many spices that you can work into your fries. Here, we will look at a number of them;


  • Oils like Olive oil, Canola oil, Avocado oil, etc.
  • Garlic powder
  • Pepper—Black pepper, Cayenne pepper
  • Salt
  • A glass of beaten egg whites
  • Dried thyme
  • Dried basil

– Ensure that all of the fries are evenly smothered with the spices before placing them inside the basket of the air fryer.

– Ensure that the fries are not placed too closely to each other within the basket. This will help ensure that the heated air is able to circulate freely and quickly.

– To achieve the best results, ensure that you use the first batch of strips as samples. Some air fryers may have their best working temperatures below 140-degree Fahrenheit. The moment you notice this, ensure that you reduce the temperature for the consequent batches.

You can serve your potato fries with any of these;

  • Baked beans
  • Tomato sauce—Ketchup
  • Gravy—Rosemary gravy
  • Cheese
