Hot take: spraying frozen fries with a little oil before they go in fixed my sogginess problem
Tried it 3 nights ago out of pure laziness and they came out crispy instead of that sad steamed texture. Anyone else doing this, or do you just crank the temp higher?
Spraying oil on frozen fries just adds a layer that traps steam underneath unless you spread them out in a single layer with room to breathe. Cranking the temp higher does the same job without extra steps, and it works on any brand right out of the bag. Save the oil spray for fresh cut potatoes where it actually does something.
