Air fryer French Fries
If you want to know exactly how long and at what temperature to cook french fries in the air fryer so they turn out crispy on the outside and tender on the inside, here’s the exact answer — plus the soaking trick, which is what really makes the difference between fries that stick together and ones that turn out perfect.

Time and Temperature for Air Fryer French Fries (Quick Table)
| Cut Type | Temperature | Approximate Time | Notes |
|---|---|---|---|
| Thin sticks | 200°C (390°F) | 15-20 min | Toss halfway through cooking |
| Potato wedges | 195°C (380°F) | 20-25 min | No need to toss if not stacked |
| Frozen fries | 200°C (390°F) | 15-18 min | No pre-soaking needed |
The time varies depending on the thickness of the cut: the thinner the fries, the less time they need, but there’s also more risk of burning if you don’t keep an eye on them toward the end.
How Long Do Fresh French Fries Take in the Air Fryer?
With fresh potatoes cut into sticks, the usual time is 15 to 20 minutes at 200°C (390°F), tossing them halfway through cooking so they brown evenly on all sides.
Ingredients
- 4 medium potatoes (starchy variety: Russet, Yukon Gold, or similar)
- 1 tablespoon extra virgin olive oil
- 1 teaspoon salt
- Black pepper, to taste (optional)
- Sweet paprika, rosemary, or garlic powder (optional, to switch up the flavor)
How to Prepare the Potatoes Before Air Frying
- Peel the potatoes and cut them into sticks or wedges of whichever thickness you prefer, making sure all the pieces are a similar size so they cook at the same rate.
- Soak them in a bowl of cold water for at least 30 minutes — this step removes excess starch and is the key to keeping them from sticking together and getting them crispier.
- Drain them well and dry them thoroughly with a clean cloth or paper towels; any leftover moisture will make them turn out soft instead of crispy.
- Toss the dried potatoes with the oil and salt, mixing well so they’re lightly coated.
Why Soaking in Cold Water Is the Step That Most Affects the Result
The starch that potatoes release when cut is what makes them stick together and cook unevenly. Soaking them in cold water removes much of that starch, which allows the air fryer’s hot air to reach the entire surface and achieve a much more even golden color.
Step-by-Step: Air Fryer French Fries
- Peel and cut the potatoes into sticks or wedges of similar size.
- Soak them in cold water for 30 minutes.
- Drain them and dry them thoroughly with paper towels.
- Toss the potatoes with the oil and salt in a bowl.
- Place the potatoes in the basket without overcrowding, so air can circulate well.
- Cook for 15-20 minutes at 200°C (390°F).
- Toss or shake the basket halfway through cooking so they brown evenly.
- If you want extra crispiness, add 5 more minutes at the end, keeping an eye on them so they don’t burn.
- Serve immediately, fresh out of the air fryer.
Do You Need to Toss the Fries During Cooking?
It’s not strictly mandatory if you’ve placed them without overcrowding, but tossing or shaking the basket halfway through cooking helps all the pieces brown evenly, especially if your air fryer has hotter spots in certain areas.
How to Tell When the Fries Are Fully Cooked
The fries should turn out golden on the outside and tender when pierced inside with a fork. If, when you try one, the center still feels hard, add 3-5 more minutes of cooking.
Common Mistakes When Making Air Fryer French Fries (and How to Avoid Them)
- They stick together → almost always from skipping the cold water soak, which removes the excess starch responsible for sticking.
- They turn out soft instead of crispy → usually from not drying them well after soaking, or using too much oil, which in excess also reduces crispiness.
- They cook unevenly → happens when the basket is too full; it’s better to cook in two batches than to overcrowd the fries into one.
- They burn on the outside before turning tender inside → tends to happen with very thin cuts at high heat; lower the temperature slightly or keep a close eye on the last few minutes.
Frequently Asked Questions About Air Fryer French Fries
Why do you need to soak the potatoes in cold water before cooking them? Soaking removes much of the starch that potatoes release when cut, which is exactly what makes them stick together and cook unevenly. With 30 minutes of soaking, you’ll notice a clear difference in the final result.
Can you make air fryer french fries with no oil at all? Yes, although a very light drizzle helps them brown better and helps the salt and spices stick. Without any oil at all, the result is slightly less golden, but still fairly crispy thanks to the air circulating at high speed.
What type of potato works best for air fryer french fries? Varieties with higher starch content, like Russet or Yukon Gold, give better results than new potatoes or firmer-fleshed varieties, since that starch (once controlled through soaking) helps achieve a crispy outside and tender inside.
How long do frozen french fries take in the air fryer? Between 15 and 18 minutes at 200°C (390°F), with no need for pre-soaking, since store-bought frozen fries usually come pre-cooked with the starch already treated during the industrial process. You’ll find all the details, cut types, and specific tricks in our frozen french fries in the air fryer guide.
Do you need to preheat the air fryer to make french fries? It’s not essential, although preheating for a few minutes helps them start browning right away. If your air fryer doesn’t have that function, simply add 2-3 extra minutes to the total time.
Why do my fries turn out soft inside instead of crispy? The most common reason is not drying them well after soaking, or using too much oil. Any leftover moisture on the surface prevents that crispy crust you’re after from forming.
Can you make potato wedges with this same method? Yes, although the time changes slightly: wedges usually need between 20 and 25 minutes at 195°C (380°F), a bit more than thin sticks, since they’re thicker and take longer to cook through.
What spices go best with air fryer french fries? Besides salt and pepper, sweet paprika, dried rosemary, and garlic powder are the most common choices. They’re added along with the oil before cooking so the flavor sticks well during cooking.
How many potatoes fit in the basket without stacking? It depends on the size of your air fryer, but as a general rule, 3-4 medium potatoes cut into sticks tend to be the limit before they get crowded. If you have more, it’s better to cook in two batches.
Is it healthier to make french fries in the air fryer than in a traditional deep fryer? Yes, since it uses only a fraction of the oil needed for traditional deep-frying, which considerably reduces the final calories without sacrificing a very similar crispy texture.
