Ingredients

• Seasoning: Simple flavors like onion, garlic, Italian herbs, and salt create a mouthwatering blend that brings these potatoes to life. The flavours here would go perfectly with my Cast Iron Chicken for a full meal!

How to make Crispy Diced Potatoes in Air Fryer

Preheat the air fryer to 400°F (205°C)

1. Start by washing the potatoes and drying them in a cloth (Image 1).
2. Then dice the potatoes into 2cm cubes (Image 2).

3. Then soak the cubed potatoes and ensure cleaned (Image 3).

4. Strain the potato cubes in a colander and dry with a tea towel (Image 4).

5. Toss cubed potatoes with olive oil, garlic powder, onion powder, dried Italian herbs and salt (Image 5).

6. Spread the seasoned potatoes in a single layer (or as evenly distributed as possible) in the air fryer basket. I have a dual airfryer so I spread the potatoes across two baskets to maximize crispiness (Image 6).

7. Cook for 20-25 minutes (Image 7).

8. Shake the basket halfway through, until crispy and golden brown. Serve with additional flakey salt and an optional crack of black pepper (Image 8).

Tips for Crispy Air Fryer Potatoes Every Time

Choosing the Right Potato

When it comes to achieving that perfect crispy exterior, the type of potato you use makes a difference. In fact, the best potatoes to use are waxy potatoes because they get the best crisp on the outside. My favorites are fingerlings, red potatoes, and Yukon Gold potatoes. 

However, you can still use a starchy potato if you like, like Russet, King Edwards, or Maris Piper, though you may want to soak the potatoes before air frying them to help remove some of the starch.

Air Frying from Frozen

You can definitely air fry cubed potatoes from frozen! Frozen potatoes make life a little easier since you don’t have to dice them yourself. Just air fry the frozen potatoes about 10 minutes longer than fresh ones. To ensure they are extra crispy and tender, always preheat your air fryer, cook on a high heat, and make sure the potatoes are thoroughly dry before adding oil.

Avoiding Sogginess

If you find your potato cubes in air fryer are not getting crispy enough, you can try soaking them for 30 minutes or more in a bowl of cold water after being diced to remove that excess starch. This helps prevent sogginess and promotes even browning. This focus on getting a crispy exterior is also vital in my recipe for Parmentier Potatoes.

Another important element is oil and avoiding stickiness. For example, to make sure they get nice and crispy, it is a good idea to add a small amount of oil to your potato cubes. If your potatoes are sticking to the air fryer basket or grate, you can also spray the basket with a tiny bit of oil or cooking spray before adding the cubes. This trick is key when you air fry potatoes cubes.

Knowing When They’re Done

You will know when your diced potatoes in air fryer are finished when they are crispy on the outside and fork tender in the center. The golden color means they are crisp, which is the easy part. To check the inside, you will need to poke one of the diced potatoes with a fork. The fork should go into the potato easily and also remove easily. 

Finally, as for exactly how long to air fry diced potatoes, I have found that 20-25 minutes is the sweet spot. Just check your potatoes for doneness at around the 20-minute mark, since all air fryers are slightly different. Mastering the timing and knowing how long to air fry potato cubes is key, just like precise timing is essential for these Amazing Air Fryer Steak Bites with Garlic Butter.

Leftover Storage and Reheat Instructions

Refrigerator: Store leftover air fried diced potatoes in the refrigerator in an airtight container for up to 4 days.

Freezer: Store leftovers in the freezer in an airtight container for up to 3 months in a regular freezer and up to 1 year in a deep freezer.

Reheat: Leftover potatoes that have been cooked in the air fryer, like these air fried potato cubes, tend to get a bit soggy when stored in the refrigerator or freezer unless you know how to reheat them properly. The best method for reheating them is to put them back in the air fryer. Just set it to “reheat” and pop your leftover diced potatoes in the air fryer.
