Alton Brown, in a recent Good Eats episode, went through the several ways to toast bread for croutons:
oven broiler / toaster oven
grill
heat gun
blowtorch (of the kind used to solder copper pipes, available cheaply at hardware stores)
I’ve seen him recommend heat guns on other occasions so I bet it would work just fine.
