Spray them with a little oil first and don't crowd the basket. I do 375 for about 8 minutes, then flip them and go another 4 to 5 minutes. The flip is the big one, mine came out soggy on the bottom until I started doing that. Also let them sit for a minute after, the inside keeps cooking a bit and the centers stop being cold. Frozen ones straight from the bag work fine this way, no thawing needed.
