Then use a spatula (ideally a fish spatula) to flip the filets over. Spread the topping over the filets, pressing it gently with a utensil into the fish. With oven-mitted hands, move the skillet to the oven and broil the fish for 2 to 3 more minutes, until crisp and golden on top. If you’re going to err, err on the side of less doneness; taste it and stick it back in if needed; if you overcook the fish just by a minute, it could be a little dry.
