Frozen French Fries — Air Fryer Time & Temp

Crispy on the outside, fluffy inside. No deep frying, no thawing, no oil splatter. Just spread, shake, and crisp up in 15–20 minutes at 400°F.

Step-by-Step Instructions
  1. 1Preheat air fryer to 400°F (200°C) for 3 minutes. This ensures the hot air starts crisping immediately when the fries go in.
  2. 2Spread frozen fries in a single layer in the basket. Do not crowd — overlapping creates steam and you get soggy fries, not crispy ones. If needed, cook in batches.
  3. 3Air fry at 400°F for 15–20 minutes. Shake the basket every 5 minutes to redistribute fries for even crisping. Don't have a shaker basket? Carefully lift the basket and give it a gentle shake over the sink.
  4. 4Check at 15 minutes. Thin-cut fries are done around 15 minutes. Thick-cut or steak fries need the full 18–20 minutes. Fries should be golden brown and crispy.
  5. 5Season immediately with salt (and any other seasoning) the moment they come out. They'll stick better to the hot surface.
💡
The #1 crispy fry secret: Don't crowd the basket. A single layer with space between each fry is the difference between crispy and soggy. It looks like too little food — trust the process.

Frequently Asked Questions
Do I need to thaw frozen fries before air frying?
No — frozen fries go straight from the bag to the air fryer basket. Thawing introduces moisture and leads to soggy, not crispy, results.
Do I need to add oil to frozen fries in the air fryer?
Most frozen fries are pre-fried and coated with oil during manufacturing, so you don't need to add more. A light spritz of oil can help for extra crispiness but isn't required.
Why are my air fryer fries soggy?
The two biggest causes: (1) crowding the basket — fries overlap and steam instead of crisping, (2) not shaking frequently enough. Shake every 5 minutes minimum.
Can I cook fresh (not frozen) fries in the air fryer?
Yes — soak raw fries in cold water for 30 minutes, pat completely dry, toss with a little oil, and cook at 400°F for 16–20 minutes, shaking every 5 minutes.
