Every baked potato recipe says the same thing: cook at 400°F for 35 to 45 minutes, depending on size. Then it never tells you what size means.
That ten minute spread is the difference between a potato that shatters when you fork it open and one with a hard, waxy core in the middle. So I did what nobody apparently wants to do. I bought a bag of russets, weighed each one on a kitchen scale, and cooked them one at a time until I had numbers that repeat. The result is the chart below, and everything else on this page exists because I got each of those steps wrong at least once first.
Quick answer: Scrub, dry, and pierce russet potatoes, rub with oil and salt, and air fry at 400°F. An 8 ounce potato takes about 35 minutes, a 12 ounce potato about 45, flipped once halfway. They are done when a thermometer in the center reads 205°F to 210°F and a knife slides in with no resistance. No foil, no preheating, no microwave head start needed.
The chart: time by weight
All times at 400°F, flipping once at the halfway mark. Weigh the potato raw.
| Weight | Rough size | Time | Check at |
|---|---|---|---|
| 6 oz | Small, palm sized | 28 to 32 min | 28 min |
| 8 oz | Standard medium | 33 to 37 min | 33 min |
| 10 oz | Large | 38 to 42 min | 38 min |
| 12 oz | Very large | 43 to 47 min | 43 min |
| 14 oz and up | Steakhouse | 48 to 55 min | 48 min |
Two notes that make the chart work:
- Buy potatoes that match. If you cook a 7 ounce and a 13 ounce potato together, one of them will be wrong no matter what you do. When I shop for these I pick potatoes within an ounce or two of each other. It matters more than any other single choice.
- Your machine is its own animal. Wattage and basket size shift these numbers by a few minutes either way. Run your first batch by the chart, note what your machine did, and adjust once. If you are converting from an oven recipe instead, the air fryer calculator does the temperature and time math for you, and the air fryer baking chart is the quick lookup for everything else you cook.
Why russets, and only russets
A baked potato is a starch delivery system, and russets have the most of it. High starch, low moisture. At around 205°F internal, those starch granules have fully burst and absorbed their own moisture, which is what fluffy means. Fork one open and it steams.
Yukon golds are lower in starch and higher in water. They bake up dense and creamy, which is lovely in other contexts and wrong here. Red potatoes are waxier still. Sweet potatoes work in the air fryer but they are a different job with different times, and they never crisp the same way because of their sugar content.
So: russets, also sold as Idaho potatoes. If small waxy potatoes are what you have, they are not a substitute here but they are excellent on their own terms, which is air fryer baby potatoes. Firm, no green patches, no sprouts. Green means solanine, and you should cut those parts away regardless of how you cook it.
The four decisions that make or break the skin
Dry it like you mean it
Surface water has to boil away before any crisping starts. A wet potato spends its first five minutes steaming its own skin soft. Towel it off completely after scrubbing.
Pierce it 8 to 10 times
A potato is a sealed pressure vessel. At 400°F the water inside becomes steam, and steam without an exit finds one. A burst potato in a basket is an impressive mess. Fork holes take ten seconds.
Use an oil that takes 400°F
Extra virgin olive oil starts smoking right around 375°F to 405°F, which is why so many kitchens fill with acrid smoke during this exact recipe. Use avocado oil or light olive oil, about half a teaspoon per potato.
Salt after the oil, then cook
Coarse salt pressed onto the oiled skin gives you the steakhouse crust. Salting early pulls moisture back out of the skin, so it goes on immediately before the basket, never twenty minutes ahead.
And never wrap it in foil. Foil traps steam, and a foil wrapped potato comes out with soft, sad skin no matter how long you cook it. Foil has legitimate uses in an air fryer, covered in when foil and parchment are safe, but this is not one of them. The storage section below has a second, more serious reason to keep foil away from baked potatoes.
How to make them
- Scrub 2 to 4 russets under running water with a brush. You are going to eat this skin. Dry them completely.
- Pierce each one 8 to 10 times with a fork, all the way around.
- Rub with oil. About half a teaspoon of avocado or light olive oil per potato, coating every bit of skin.
- Salt generously. Coarse kosher or sea salt, pressed on so it sticks.
- Into the basket, cold start. Single layer, at least half an inch between potatoes. No preheating needed, because a potato is so dense that a three minute head start does nothing measurable. When preheating actually matters covers the bakes where it does.
- Air fry at 400°F for the time in the weight chart, flipping once halfway with tongs.
- Test properly. A thermometer in the center should read 205°F to 210°F. No thermometer? A thin knife should slide to the center with zero resistance, and the potato should give when you squeeze it with an oven mitt. If you feel a firm core, give it 5 more minutes. The skin lies. The knife does not.
- Cut immediately. Slice a cross in the top, push the ends toward each other so it blossoms open, and let the steam out. A baked potato left sealed keeps steaming inside and the fluffy interior goes gluey. Butter first, then everything else.
Cooking more than two
This is where air fryer baked potatoes stop being simple, and where most recipes go quiet. Every potato you add blocks airflow and soaks up heat.
| Batch | What changes |
|---|---|
| 1 to 2 potatoes | Chart times as written |
| 3 to 4 potatoes | Add 3 to 5 minutes, flip and rotate positions halfway |
| 5 or more in a basket | Do not. Skins go leathery before centers finish |
| Dual basket | Split them, same chart times, swap baskets at the flip |
| Oven style on racks | Chart plus 5 minutes, swap racks halfway |
The positions inside the basket are not equal either. The back corners run hottest in most machines. When I flip at halfway, I also move the back potatoes to the front. If one potato is stubbornly behind the others at the end, it was probably sitting in the cool spot by the door. Oven style machines handle crowds far better, and the differences are in basket versus oven-style air fryers. If you have never measured your basket, the pan size calculator tells you how many will genuinely fit in a single layer.
For a crowd, cook in waves and hold the finished ones in a cooler or a warm oven. A baked potato holds its heat for a solid 30 minutes if you do not cut it open.
Storage, and the foil mistake that actually matters
Leftover baked potatoes keep 4 days in the fridge. Cool them within two hours, and here is the part worth knowing: do not store a cooked potato wrapped in foil at room temperature. Foil seals out oxygen, and a warm, airless, low acid environment is exactly what botulism bacteria want. This is a documented food safety issue, not internet caution. Unwrap, cool, refrigerate in an open or loosely covered container.
To reheat: 400°F in the air fryer for 5 to 8 minutes, straight from the fridge. This is the good news portion of the page, because the air fryer resurrects a day old baked potato better than any other method. The skin re-crisps to almost original condition, which a microwave will never do. Same principle as reheating fried chicken in the air fryer: dry circulating heat gives crispness back instead of steaming it away.
The scooped-out skins are worth keeping too. Crisped on their own they become air fryer potato peels, which is the cheapest snack on this site.
Or go one better and make twice baked potatoes. Halve the leftovers, scoop most of the flesh into a bowl, mash it with butter, cheese, and a spoon of sour cream, refill the skins, and air fry at 370°F for 8 to 10 minutes until the tops brown. Honestly worth baking extra potatoes just to end up here.
Toppings that hold up
The classic build is butter, sour cream, chives, shredded cheddar, and something crisp and salty on top. Do the butter while the potato is steaming hot so it soaks in, add cheese next so it melts, then the cold things.
- Broccoli cheddar, with the broccoli given 6 minutes in the air fryer first so it chars a little.
- Chili and cheese, the reason to make a 14 ounce potato dinner.
- Greek yogurt, everything bagel seasoning, and scallions when I am pretending to be virtuous.
- Crumbled bacon, cooked in the same machine before the potatoes go in. The air fryer bacon method takes 10 minutes and the potatoes do not mind waiting their turn.
If you like potatoes in crispier formats, the same russets make accordion potatoes for something dramatic, potato chips for snacking, or hash browns the next morning. Tater tots and sweet potato fries round out the family.
Troubleshooting
If the same faults follow you across different bakes rather than just potatoes, the troubleshooting guide works symptom-first through all of them.
| What you got | Why | Fix |
|---|---|---|
| Hard center, done skin | The potato was bigger than the time you gave it, or mismatched sizes shared a basket. | Weigh next time. Rescue this one with 5 to 8 more minutes, the skin can take it. |
| Leathery skin | Too many potatoes, wet skin going in, or foil. | One layer, bone dry, naked potato. |
| Wrinkled and collapsing | Overcooked, usually a small potato given big potato time. | Still edible. The chart exists for this. |
| The machine smoked | Extra virgin olive oil at 400°F is at its smoke point. | Switch to avocado or light olive oil, and wipe old grease out of the drawer. Persistent smoke: how to prevent burning in an air fryer. |
| Bland skin | Salt went on before the oil, or too early, and fell off or dissolved. | Oil first, salt pressed on second, cook immediately. |
| Gluey middle, not fluffy | The potato sat sealed after cooking and kept steaming itself. | Cut it open the moment it comes out. If everything you cook seems damp rather than crisp lately, how to make bakes crispy in the air fryer applies here too. |
Forty minutes of basket time against an hour of full oven for two potatoes is the case this machine makes best, and the running cost calculator will price it against your own rate.

Frequently asked questions
QHow long does a baked potato take in the air fryer?
At 400°F, an 8 ounce russet takes 33 to 37 minutes and a 12 ounce russet takes 43 to 47 minutes, flipped once halfway. Time depends on weight, not the clock, so weigh the potato and cook to 205°F internal. A small 6 ounce potato can be done in 28 minutes, and a 14 ounce steakhouse potato can want nearly an hour.
QWhat temperature is best for air fryer baked potatoes?
400°F. Lower temperatures cook the inside fine but never crisp the skin. If your machine tops out at 390°F or so, add 5 minutes to the chart times and expect a slightly softer skin.
QDo you have to poke holes in potatoes before air frying?
Yes. Eight to ten fork holes let steam escape. Without them, pressure builds inside the sealed skin and the potato can split or burst in the basket. It takes ten seconds and skipping it is not a risk worth the mess.
QShould you wrap potatoes in foil in the air fryer?
No. Foil traps steam and gives you soft skin, which defeats the point of the method. It also matters for storage: never leave a cooked potato wrapped in foil at room temperature, because the sealed, airless environment is a documented botulism risk. Unwrap, cool, and refrigerate loosely covered.
QHow do you know when an air fryer baked potato is done?
A thermometer in the center reads 205°F to 210°F, or a thin knife slides through with no resistance and the potato gives when squeezed with an oven mitt. Skin color is not a reliable signal, because the skin finishes looking done well before the center catches up.
QDo you need to preheat the air fryer?
No. A potato is dense enough that a preheat changes nothing you can measure. Cold start, full time, done. Save the preheat for thin batters and short bakes where it genuinely matters.
QShould I microwave the potato first to speed it up?
You can knock 15 minutes off by microwaving 5 minutes first, but the skin pays for it. Microwaved potatoes steam from the inside out, and the skin never fully recovers its crisp. If the goal is the fastest decent potato, do it. If the goal is the best one, do not.
QCan I bake other things at the same time?
Not in the same basket if they need a different temperature, and most things do. In a dual basket machine, potatoes in one drawer and a main in the other is one of the best uses of the second basket. What shares heat happily is covered in what you can and cannot bake in an air fryer.
QAre air fryer baked potatoes faster than the oven?
About 25 percent faster, 40 minutes against roughly 60 at the same temperature, and the air fryer does not heat the kitchen. The skin also comes out crisper because the fan strips moisture off the surface the entire time. For what the difference costs in electricity, the running cost calculator will give you the figure for your own rate.
