⚙ Oven roasting: How to Do It and How Long It Takes

Oven roasting takes 28 min most of the time (usually between 16 min and 40 min).

Give it room in the pan: crowded vegetables steam instead of browning.

A fillet is done when the flesh is opaque even in the thickest part and flakes when pressed with a fork; a few more minutes in the oven and it dries out.
The fish is done when the flesh near the backbone is white and flakes easily with a fork; a white, opaque eye is another sign.
