Why air fryer diced potatoes?

The air fryer offers a healthier alternative to deep-frying, as it requires only a small amount of oil to achieve a perfect crisp. Additionally, air frying reduces the excess starch on the potato surface, making your crispy air fryer potatoes much more of a guilt-free delight.

Making crispy air fryer potatoes is not only easy but also opens up a world of possibilities for delicious side dishes. With simple ingredients, minimal prep, and a variety of seasonings to choose from, you can create the best crispy potatoes that will accompany any meal.

What type of potatoes to use

When it comes to making crispy potatoes in the air fryer, the best results are achieved with potatoes that have a blend of waxy and floury characteristics. Here in the UK, I like to use King Edwards and Maris Pipers. This combination ensures that the outside of the diced potato is crunchy, whilst maintaining its shape.

These also work well for roast potatoes, too. Other types of potatoes that work include russet potatoes, Yukon gold potatoes, and red potatoes. Experimenting with different types of potatoes and adjusting seasoning to your taste preferences will help you discover your favourite combination for crispy air fryer potatoes.

How to achieve extra crispiness

For crispy air fryer diced potatoes every single time, I recommend soaking the potatoes before cooking, so that you remove as much of the starch as possible. Too much starch can mean potatoes don’t cook evenly and also create a sticky texture on the outside, which inhibits them from getting that all-important golden brown crispy texture.

Soaking diced potatoes - Cook Simply
Once your potatoes are cubed, put them in a large bowl and cover with cold water for around half an hour or even longer, then rinse them and make sure to pat dry with a clean tea towel or paper towel. If you’re short on time, I find that even soaking them in cold water for around 10 minutes and then rinsing them again in running cold water makes all the difference.

Here’s a list of ingredients

  • fresh potatoes of your choice
  • olive oil or vegetable oil
  • paprika
  • garlic powder
  • onion powder
  • black pepper
  • salt
  • oregano
  • fresh herbs including parsley (optional)

How to cook diced potatoes in an air fryer

Start by peeling your potatoes and then dicing them into even-sized cubes. They don’t have to be perfectly uniform – around 2cm/1-inch cubes are fine. Then it’s at this point you can soak and rinse your dice potatoes in cold water to remove excess starch. Make sure to pat them as dry as possible with paper towels or a clean tea towel.

Now it’s time to season to perfection. Add the diced potatoes to a large bowl and then add the olive oil, garlic powder, paprika, onion powder, salt, pepper, and oregano. The beauty of this recipe lies in the ability to experiment with different seasonings to suit your taste buds – for instance, if you’d prefer these to be fiery and spicy, you could add cayenne pepper or chilli powder. Don’t be shy – give the potatoes a good shake in the bowl to ensure an even coating.

How long to cook diced potatoes in the air fryer?

Preheat your air fryer, to around 200°c/400°F, or as per your air fryer’s instructions. Put the seasoned potato cubes into the air fryer basket, spreading them out in a single layer. If needed, cook in batches to avoid overcrowding, as the hot air needs room to be able to make the diced potatoes as crispy as possible.

Dependent on your air fryer model you’ll want to air fry your diced potatoes for about 20-25 minutes at 195°c/380°F, making sure to keep an eye on them – giving your air fryer basket a shake several times during cooking.

When the diced potatoes are golden brown and have a crispy skin, they’re ready to come out of the air fryer. I like to sprinkle some fresh parsley over the top before serving, but this is entirely optional.

What can I serve them with?

Air fryer diced potatoes are the perfect side dish to so many meals including meats such as chicken, beef, or lamb. It’s also a great breakfast potato served alongside your bacon or eggs or even added to burritos or kebab wraps. If you’re anything like my kids, who love crispy potatoes, then you can devour them on their own with some tomato ketchup or mayonnaise.

Different seasoning variations

Have fun and experiment with different flavour combinations. I also like to make air fryer Greek potatoes, or spicy cajun potatoes. Why not give these a go below:

  • Lemon juice and oregano, then sprinkle some feta cheese over the top before serving
  • Add cajun spice seasoning alongside the paprika
  • How about adding mixed herbs, and garlic powder, then sprinkling parmesan cheese over the top before serving?

What about leftovers?

If you happen to have leftovers (which is a rare occurrence!), store them in an airtight container and you can keep in the fridge for up to three days. Reheat them in the air fryer for a few minutes to maintain their crispiness. These crispy air fryer potatoes can also be frozen for up to three months, making them an excellent option for those hectic days when you need a quick and delicious side dish. Just cook them from frozen in the air fryer for around 20-25 minutes at around 180°c/320°F.

Tips to help you get crispy diced potato in the air fryer

  1. Ensure that you cut the potatoes into uniform cubed pieces. This helps in even cooking, ensuring that all pieces achieve the desired level of crispiness.

  2. Preheat your air fryer before adding the potatoes. This jump-starts the cooking process and contributes to a crispy exterior.

  3. Avoid overcrowding the air fryer basket. Arrange the potato pieces in a single layer to allow proper air circulation, promoting even cooking and crispiness.

  4. While the air fryer uses less oil than deep frying, using a bit of oil is still essential for achieving crispy results. Toss the potatoes in a small amount of olive oil or vegetable oil before air frying.

  5. Shake or toss the potatoes halfway through the cooking time to ensure that all sides are exposed to the hot air, promoting even browning.
