The air fryer produces the best baked potato you can make at home — a genuinely crispy, salted skin with a completely fluffy, steam-soft interior. The oven gets close but takes twice as long and never quite achieves the same crackly exterior. The microwave is fast but the skin stays soft and rubbery. The air fryer does both in 35–45 minutes with almost zero effort.
| Potato Size / Type | Temperature (°F) | Cooking Time | Notes |
|---|---|---|---|
| Small potato (150–180g) | 400°F | 30–35 min | Flip halfway |
| Medium potato (200–250g) | 400°F | 35–42 min | Flip halfway |
| Large potato (300–350g) | 400°F | 42–50 min | Flip halfway; pierce to test |
| Extra large potato (400g+) | 400°F | 50–60 min | Flip halfway; thermometer recommended |
| Sweet potato (baked whole) | 375°F | 30–40 min | Flip halfway; size varies widely |
| 2 potatoes at once | 400°F | Add 5–8 min | Reduce airflow; check both |
| Twice-baked potato (finish) | 375°F | 8–12 min | Already cooked; heat through only |
A baked potato is done when a skewer or sharp knife slides through the center with zero resistance — it should feel like going through soft butter. The skin should feel dry, taut, and slightly rigid when squeezed with a towel, not soft and yielding. Internal temperature should reach 210°F (99°C) at the center for a fully fluffy interior.
Ingredients (2 servings): 2 large russet potatoes (300g each), 1 tbsp olive oil, 1 tsp coarse sea salt. Toppings: 4 tbsp sour cream, 50g grated cheddar, 4 rashers crispy bacon (cooked and crumbled), 2 spring onions (sliced), salt and pepper, optional: hot sauce.

A medium potato (200–250g) takes 35–42 minutes at 400°F. Small potatoes are done in 30–35 minutes, large potatoes (300–350g) need 42–50 minutes, and extra large can take up to 60 minutes. Always test with a skewer — the potato must offer zero resistance at the center before it's ready, regardless of time.
Never — not if you want crispy skin. Foil traps steam inside, which keeps the skin soft and pale. The entire advantage of the air fryer for baked potatoes is the dry circulating heat that crisps the skin while steaming the interior from within. Go foil-free, coat in oil and salt, and let the air fryer do its job.
Three steps: dry the potato completely after washing, rub all over with olive oil, then coat in coarse salt. The oil conducts heat into the skin and promotes browning; the coarse salt draws out residual surface moisture and creates a crunchy, seasoned crust. Cook at 400°F without foil and the skin will be genuinely crispy.
Yes — most 5-quart or larger air fryers can fit 2 medium potatoes comfortably. Cooking 2 at once reduces airflow around each potato and adds 5–8 minutes to the cooking time. Check both with a skewer before serving — they may finish at slightly different times if they're not perfectly the same size.
Russet potatoes (also called Idaho or floury potatoes) are the clear choice. Their high starch content produces the fluffiest interior and their thick, rough skin crisps beautifully at 400°F. Avoid waxy varieties like new potatoes or red-skinned potatoes for baking — they produce a denser, waxier interior and the skin doesn't crisp the same way.
Cooking times vary by air fryer model and potato size. Always test with a skewer before serving — zero resistance at the center is the only reliable doneness indicator. Never use foil.
