🥘 Ingredients
Potatoes – A floury white variety such as Maris Piper or King Edward is ideal. In the US, Yukon Gold or red potatoes work well. White potatoes are also suitable.
Olive oil – About one tablespoon, or use a light spray to reduce calories. Vegetable oil is an acceptable alternative.
Seasonings – Sea salt, black pepper, garlic powder and smoked paprika are simple and effective.
🔪 Instructions
Follow these straightforward steps to make roast potatoes in an air fryer.
The recipe card with quantities and the full method is below.
Top tips
- Cut potatoes into uniform 4–5 cm pieces. Smaller chunks increase surface area and shorten cooking time.
- Soak for 30 minutes to remove starch, which helps create a crunchy exterior.
- Dry thoroughly after soaking; any surface moisture prevents crisping.
- Preheat the air fryer so potatoes start cooking at the right temperature. Follow your model’s guidance if needed.
- Keep potatoes in a single layer and avoid overcrowding to ensure even browning.
- If you prefer extra-crisp roasties and have time, parboiling before air frying will improve texture.
- For a richer flavour, roast in goose or duck fat instead of oil.
- Finish with fresh herbs such as rosemary, thyme or chopped parsley for aroma and colour.
Reader tip
“5 minutes before they are cooked, mix some goose fat, a bit of marmite and hot water, then toss with the potatoes. My wife usually dislikes marmite but loves it on roast potatoes—worth a try!” Paul
🍴 Serving suggestions
These quick air fryer roast potatoes pair well with a traditional roast—think roast chicken, gammon, roast beef—or hearty mains like slow-cooked lamb or pork chops. They’re also great alongside a simple sausage casserole for an easy weeknight dinner.

📖 Variations
Try these simple variations to change the flavour:
- Add fresh herbs like rosemary or thyme before cooking, or garnish with parsley after cooking.
- For heat, add a pinch of chilli powder or cayenne pepper.
- Add minced garlic or garlic powder for a garlicky note.

Other seasoning ideas include Italian herbs, Cajun spice, fajita seasoning, oregano or onion powder. You can also make sweet potato fries in the air fryer; they don’t need soaking since they contain less starch. To make chips, cut potatoes into thicker strips and increase cooking time as needed.
🥡 Storage
These roast potatoes are best served immediately while they’re at their crispiest.
Store: Refrigerate leftovers in an airtight container for up to 3 days.
Reheat: Re-crisp in the air fryer for about 5 minutes to restore crunch.
Freeze: Freeze cooked potatoes for up to 3 months. Air fry from frozen at 190°C (375°F) for about 15 minutes or until heated through and crisp.
❓ FAQs
Soaking removes excess starch, which helps the potatoes crisp and prevents them from sticking together.
Many models benefit from preheating to reach the correct cooking temperature quickly—check your air fryer’s instructions.
