1. Do not thaw the fries. They turn out much crisper when air fried from frozen.
2. Your air frying time will be the same unless you use very thick cut fries. If you are cooking a larger batch, do it in two batches.
3. Avoid much overlapping of the fries in the air fryer basket, or they will cook unevenly.
4. There is no need to brush or spray them with oil as they already have a lot of oil in them.
5. Do not let the fries overlap in the air fryer basket or they will not cook evenly.
