Sweet Potato Air Fryer

In our original air fryer cookbook, the complete air fryer cookbook we had great fun with baked potatoes and taught you how to make a baked potato bar.

So how could we help you with your baked potatoes in book 2 you may ask, in Air Fryer Easy Everyday?

Well, instead of white potatoes, we opted for sweet potatoes. But what amazes me about the sweet potato, is the zillion shapes and sizes they come in and how hard it is to figure out how long to cook sweet potatoes in air fryer.

We decided to have a raw picture in the cookbook showing off the size from tiny to super-size and to spend days, weighing sweet potatoes, air frying and treating it like a big science experiment.

By the end of it, we knew exactly how long every sweet potato takes in the air fryer!

Why Do My Sweet Potatoes Burn In The Air Fryer?

Sweet potatoes burn in the air fryer because they are very fast cooking. Then you focus on the sweet potato being crispy and because its not as naturally crispy as white potatoes, you end up burning it.

Also, the skin on the sweet potato is very delicate, so it goes golden much quicker than a white potato.

Why Soak Sweet Potatoes Before Air Frying?

Some people prefer to soak potatoes before air frying, thinking that it will remove the excess starch and help them taste better.

I am not one of those people. It results in overly soggy sweet potatoes and doesn’t make a difference to the taste.

Why Do You Put Oil On Sweet Potatoes Before Baking?

You put oil on your sweet potatoes before air frying them for a crispy texture and also to keep them moist. But don’t worry you don’t need a lot of oil on your air fryer baked sweet potato.

What we recommend is a plate. Any dinner plate will do the trick as you need it big enough to roll a whole sweet potato on.

How Long To Cook Sweet Potato In Air Fryer?

So, as you can see above, the sweet potato air fryer time, varies a lot based on the size of the sweet potato.

Also note that a sweet potato that is pointy rather than chunky will cook a little quicker.

We divide the sweet potato sizes into small, medium, large, xl, xxl, and gigantic. Then what we also do is weigh them and then you can use the time and temp chart as your go to depending on the size of your sweet potato and it works as the ideal guide for understanding your sweet potato air fryer time and temp.

• 150g/5½oz (small) – 20 minutes
• 300g/10½oz (medium) – 25 minutes
• 450g/1lb (large) – 45 minutes
• 550g/1¼lb (extra large) – 55 minutes
• 700g/1lb 9oz (extra extra large) – 60 minutes
• 900g/2lb (gigantic) – 75 minutes

For example, with your baked sweet potatoes in air fryer you might have a really big one and its 700g, then you know we are calling it a XXL and to cook it for 60 minutes.

Whilst those tiny little ones that are out of season, would be a small and weigh around 150g and you can fit loads in your air fryer. You then know you can do them in just 20 minutes.

Of course, these time and temps for baking sweet potatoes in air fryer, is also in our new cookbook Air Fryer Easy Everyday.

Looking at the time and temps above for an air fryer sweet potato, gives you a prime example of how potatoes doneness can vary so much based on size.

That rule applies to any potato in the air fryer. This is probably why we love doing cubed potatoes as they are often fork soft after 12 minutes vs a large sweet potato which is 60 minutes.
