Frozen fries in the air fryer are better than in the oven — crispier on the outside, fluffier on the inside, and done in half the time. No preheating a full oven, no soggy bottom, no flipping tray after tray. Just shake the basket once and you're done.
| Fry Style | Temperature (°F) | Cooking Time | Notes |
|---|---|---|---|
| Thin-cut fries (shoestring) | 400°F | 10–15 min | Shake at 7 min |
| Standard-cut fries | 400°F | 14–18 min | Shake halfway |
| Thick-cut / steak fries | 400°F | 15–20 min | Shake at 10 min |
| Crinkle-cut fries | 400°F | 14–18 min | Shake halfway |
| Waffle fries | 400°F | 12–16 min | Single layer for best crunch |
| Sweet potato fries (frozen) | 400°F | 12–16 min | Watch closely — burn faster |
| Curly fries | 400°F | 10–14 min | Shake at 7 min |
| Seasoned / battered fries | 400°F | 13–17 min | Don't overcrowd |
All frozen fries go straight from the freezer — no thawing, no oil needed. The air fryer handles the rest. Times are based on a standard 400g (14 oz) portion. Larger quantities need a few extra minutes and may produce softer fries if the basket is too full.
Ingredients (2 servings): 400g frozen standard-cut fries, 1 tsp garlic powder, 2 tbsp grated parmesan, ½ tsp dried parsley, pinch of chili flakes (optional), salt to taste.

Thin-cut frozen fries take 10–15 minutes at 400°F. Standard and crinkle-cut fries take 14–18 minutes. Thick-cut or steak fries can need up to 20 minutes. Check at the lower end of the range and add time in 2-minute increments until you reach your preferred crispiness.
No — frozen fries are already pre-coated in oil during manufacturing. Adding more oil doesn't make them crispier; it makes them greasier. Cook them straight from the bag. The exception is homemade or very plain frozen fries with no coating — a light spray of oil helps those crisp up.
The most common cause is overcrowding the basket. When fries are piled on top of each other, steam gets trapped and they end up soft rather than crispy. Fill the basket no more than halfway, increase the temperature to 400°F, and make sure to shake halfway through cooking.
Preheating for 3–5 minutes gives noticeably crispier results, especially for thin-cut fries. It's not strictly necessary — fries will still cook without preheating — but the first few minutes in a cold air fryer produce steam rather than crunch, which affects the final texture.
Only if your air fryer has a large enough basket to hold them in a roughly single layer. Most standard 5–6 quart air fryers can handle 400–500g (roughly one standard bag) comfortably. For larger quantities, cook in batches and keep the first batch warm in a 200°F oven while the second batch finishes.
Cooking times vary by air fryer model, fry thickness, and basket size. Always check crispiness before serving and adjust time in small increments to suit your preference.
