Make Ahead Tip: Bake the casserole, let cool for 1 hour, cover and refrigerate for up to 1 day; let stand at room temperature for 30 minutes, then reheat at 400°F for 40 minutes.
Tips: Bottled clam juice can be very high in sodium. We like Bar Harbor brand, which has 120 mg sodium per 2-ounce serving. Look for it in the canned-fish section or the seafood department of your supermarket.
Overfishing and trawling have drastically reduced the number of cod in the U.S. and Canadian Atlantic Ocean and destroyed its sea floor. For sustainably fished cod, choose U.S. Pacific cod or Atlantic cod from Iceland and the northeast Arctic. For more information, visit Monterey Bay Aquarium Seafood Watch at seafoodwatch.org.
We like Ian's brand of coarse dry whole-wheat breadcrumbs, labeled “Panko breadcrumbs.” Find them in the natural-foods section of large supermarkets. To make your own, trim crusts from firm sandwich bread. Tear the bread into pieces and process in a food processor until coarse crumbs form. (To make fine dry breadcrumbs, process until very fine.) Spread on a baking sheet and bake at 250°F until dry, about 10 to 15 minutes. One slice of bread makes about 1/3 cup dry breadcrumbs.
To peel shrimp, grasp the legs and hold onto the tail while you twist off the shell. To devein shrimp, use a paring knife to make a slit along the length of the shrimp. Under running water, remove the dark tract with the knife tip.
