Frozen sweet potato fries in the air fryer
Frozen sweet potato fries takes 14 to 18 minutes at 395°F (200°C) in an air fryer straight from frozen, shaken or turned at 8 minutes.
What to know about air frying frozen sweet potato fries
Cosori puts frozen sweet potato fries at 395°F for 14 to 18 minutes with a shake — identical numbers to thin-cut regular fries on the same chart. They do not behave identically, though. Sweet potato has far more sugar and much less starch, so it browns faster and crisps less; a sweet potato fry that looks the same colour as a regular one at the same moment is further along than it appears.
The mistake people make
Expecting them to go as rigid as regular fries and leaving them in until they do. They will not. Sweet potato lacks the starch structure that makes a potato fry snap, so waiting for that texture just gets you burnt sugar on the outside.
How to tell when it's done
Dark orange with browned, slightly blistered edges and a soft interior. A little flex is normal and correct for sweet potato — judge them by colour at the edges rather than by rigidity.
