For me, the air fryer has ruined oven-roasted potatoes. I’m only half kidding: I haven’t put potatoes in the oven for months. I’m staying true to the air fryer because it crisps up the outside of a potato like you brushed it with magic, while the insides stay creamy and tender. Even better, the air fryer cooks potatoes faster than the oven — which only partially makes up for me being routinely behind schedule.
I have made every kind of potato you can think of in the air fryer, and each version has its own optimal temperatures and cook times. A whole baked Russet, a tray of red potato wedges, and a basket of sweet potato fries are three completely different cooking jobs. So here’s where I pull it all together — quick-reference cook times for various potato iterations, my best tips for getting them crispy, plus some links to full guides when you want the deep dive.

Tips for air fryer potatoes
Here are some habits that’ll help you get consistently delicious air-fryer potatoes.
- If you have time, soak diced potatoes. Soaking cut potatoes in cold water for 30 minutes pulls out the surface starch, which is the trick behind extra-crispy fries and home fries. Just dry them completely afterward. If you’re in a hurry, skip the soak. The air fryer is forgiving and you’ll still get great results.
- Dry the potatoes really well. Wet potatoes steam instead of crisping, so make sure you get them fully dry before cooking. You can pat them dry with a paper towel and set them out on a clean kitchen towel for 10 or 15 minutes, flipping once.
- Toss cut potatoes with cornstarch. After soaking and drying, toss 1 teaspoon of cornstarch into every 1 pound of potatoes. Toss the potatoes in oil after they’re dusted with cornstarch.
- Give them space. Hot air needs to circulate around the potatoes to crisp them. Keep the potatoes in one layer in your basket. For whole baked potatoes, I do four medium ones at most. If you’re feeding a crowd, cook in batches. Leftover air fryer potatoes reheat beautifully in about 3 minutes.
- Poke whole potatoes with a fork. A few jabs minimizes the risk of exploding potatoes inside your air fryer.
- Shake or flip halfway through. For diced or fried-style potatoes, give the basket a good shake at the halfway mark. For whole baked potatoes, flip them once.
- Oil and salt go on before cooking, not after. Toss potatoes with about a tablespoon of oil and a generous pinch of salt before they go in. Oil added at the end makes them greasy; oil added at the start makes them crispy.
A quick note on your air fryer
Cooking times vary between models. Basket-style air fryers can run hotter and faster than oven-style ones, while a 3-quart cooks faster than an 8-quart. The times above are starting points. If your potatoes need another 2 or 3 minutes, just pop them back in. It’s hard to overcook air-fryer potatoes unless you completely forget to check on them.
That’s the whole game. Pick your potato, follow the linked recipe, and you could be deep in crispy-potato territory in under an hour.
