Baked potatoes in an air fryer develop crispy skins and fluffy interiors, and the total time depends on the potato’s size and your specific model. So, how long to put a baked potato in an air fryer? Most medium potatoes need 35 to 45 minutes at 400°F (200°C).
That range covers the average russet potato. Smaller ones cook faster. Larger ones take longer. Your air fryer brand also matters a bit.
This guide breaks down exact times by size, gives you a simple step-by-step method, and covers the mistakes that lead to hard centers or burnt skins.
How Long To Put A Baked Potato In An Air Fryer
The short answer is 35 to 45 minutes for a medium potato at 400°F. But “medium” means different things to different people. So here is a clearer breakdown.
Time Chart By Potato Size
- Small potato (5 to 7 oz): 30 to 35 minutes
- Medium potato (8 to 10 oz): 35 to 45 minutes
- Large potato (11 to 14 oz): 45 to 55 minutes
- Extra large potato (15 oz and up): 55 to 65 minutes
These times assume a preheated air fryer at 400°F. If you skip preheating, add about 5 minutes.
Russet potatoes work best. They have a high starch content, which gives you that fluffy inside. Yukon Gold potatoes also work, but they come out a bit creamier and less fluffy.
Why Air Fryer Models Change The Time
Not all air fryers run at the same true temperature. Some run hot. Some run cool. A model that runs 25 degrees hot can finish a potato 5 to 8 minutes faster.
Basket size matters too. A small basket holds one or two potatoes. A large one holds four or more. More potatoes means less air flow, which means more time.
If your air fryer tends to run hot, drop the temp to 390°F. If it runs cool, keep it at 400°F and check the potato at the 40 minute mark.
Step-By-Step: How To Bake A Potato In An Air Fryer
Follow these steps and you will get a crispy skin with a soft center every time.
- Wash and dry the potato. Scrub off any dirt under running water. Dry it well with a paper towel. Wet skin steams instead of crisping.
- Poke holes in the potato. Use a fork to pierce it 6 to 8 times on all sides. This lets steam escape and keeps the potato from bursting.
- Rub with oil. Coat the skin with a thin layer of olive oil or avocado oil. This helps the skin crisp up and holds the salt in place.
- Season the skin. Sprinkle on kosher salt. You can add black pepper, garlic powder, or rosemary if you like.
- Preheat the air fryer. Set it to 400°F for 3 to 5 minutes. Preheating gives you a head start on the skin.
- Place the potato in the basket. Leave space around it. Do not stack potatoes on top of each other.
- Cook for 35 to 45 minutes. Flip the potato halfway through with tongs. This helps both sides crisp evenly.
- Check for doneness. Pierce the center with a knife or skewer. It should slide in with no resistance.
- Rest for 5 minutes. This lets the inside finish steaming and firm up. Then slice it open and serve.
How To Tell When The Potato Is Done
The best test is a skewer or thin knife. Push it into the thickest part of the potato. If it goes in easily, the potato is done. If there is any pushback, give it 5 more minutes.
You can also squeeze the potato with a clean towel. A done potato gives slightly under pressure. A raw one feels rock hard.
Do not rely on the skin color alone. A dark, crispy skin does not always mean the inside is cooked. Always test the center.
Tips For The Best Air Fryer Baked Potato
Choose The Right Potato
Russets are the top pick. They bake up light and fluffy. Avoid waxy potatoes like red potatoes. They stay firm and dense, which is not what you want in a baked potato.
Pick potatoes that are firm and free of soft spots. Uniform size helps them cook at the same rate if you are making more than one.
Do Not Skip The Oil
Oil does two things. It helps the skin turn crisp and golden. It also helps the salt stick. A dry potato comes out dull and tough.
Use just enough oil to coat the skin. Too much oil drips into the basket and can smoke.
Space Matters
Overcrowding is the number one reason air fryer potatoes come out uneven. Hot air needs to move around each potato. If you fill the basket, the potatoes steam instead of roast.
Cook in batches if needed. A single layer with a little gap between each potato is ideal.
Flip Halfway Through
Flipping is a small step with a big payoff. It exposes the bottom of the potato to direct heat. This gives you a crispy skin all the way around, not just on top.
Use tongs so you do not burn your fingers. The potato will be hot at the halfway point.
Common Mistakes To Avoid
- Not poking holes: The potato can burst and make a mess inside the air fryer.
- Skipping the preheat: Your potato will need extra time and the skin may not crisp as well.
- Using a wet potato: Moisture on the skin turns to steam and stops the crisping process.
- Cooking at too high a temp: Above 400°F, the skin can burn before the center cooks.
- Cutting it open too soon: Let it rest 5 minutes so the inside sets up.
What About Wrapping In Foil?
Do not wrap the potato in foil in an air fryer. Foil blocks the hot air from reaching the skin. You will end up with a soft, pale skin instead of a crispy one. Save the foil for oven baking if you prefer that style.
Can You Cook More Than One At A Time?
Yes, as long as they fit in a single layer. Add 5 to 10 minutes to the total time when cooking two or more. Check them at the early end of the range and test with a skewer.
Final Thoughts
A baked potato in the air fryer is simple once you know the timing. Medium potatoes take 35 to 45 minutes at 400°F. Small ones take about 30 minutes. Large ones can take up to an hour.
Poke, oil, salt, and flip halfway. Test with a skewer before you pull it out. Follow those steps and you will get a crispy skin with a fluffy center every single time.
