Cubed potatoes are the fast one: no parboiling, no pan on the stove, just an even dice straight into the basket. They come out crisp at the corners and fluffy inside in about twenty minutes, which makes them a weekday side or a breakfast potato rather than a Sunday roast.
Ingredients
Quantities for 1 lb (450g) potatoes, cubed - the times on this page assume that much in the basket.
- 1 lb (450g) potatoes, peeled and cut into 1-inch cubes
- 1 tbsp olive oil
- 1 tsp dried rosemary
- 1/2 tsp garlic powder
- Flaky salt and black pepper
How to air fry cubed potatoes
- Peel the potatoes and cut them into even 1-inch cubes - uneven ones finish at different times - then pat them properly dry and toss with the oil, rosemary, garlic powder, flaky salt and pepper.
- Preheat the air fryer to 380°F (195°C).
- Add the fresh cubed potatoes to the basket. Shake every 5 minutes.
- Cook for about 20 minutes, shaking the basket every 5 minutes.
Pro tip
Dry the cubes thoroughly after cutting - a wet surface pins itself near 212°F and cannot brown until the water is gone.
How to tell when it's done
Look for deep golden, crisp edges and a piece that crushes easily against the side of a fork. A couple of shakes makes sure every side browns, not just the bottoms.
Converting from an oven recipe
If your recipe is written for a conventional oven, lower the temperature by about 25°F (15°C) and reduce the time by roughly 20% to land near 380°F for 20 minutes. Need a different starting point? Use the conversion calculator.
Air fryer cubed potatoes: FAQ
How long does it take to air fry cubed potatoes?
Air fry cubed potatoes at 380°F (195°C) for about 20 minutes, shaking the basket every 5 minutes. That's for 1 lb (450g) potatoes, cubed in a single layer; adjust slightly for a fuller basket or a different model.
What temperature do you air fry cubed potatoes at?
Set the air fryer to 380°F (195°C). If you're converting an oven recipe, that's roughly 25°F (15°C) below the oven temperature, with the time cut by about 20%.
Do I need to preheat the air fryer for cubed potatoes?
A 2-3 minute preheat gives the most accurate timing and the best browning, but it isn't essential - if you skip it, add a minute or two to the cook time.
