Make Ahead Tip: Cover and refrigerate cream sauce (Steps 1 & 2) for up to 1 week or freeze for up to 3 months. Defrost overnight in the refrigerator or using the defrost setting on your microwave.
Tip: To make your own fresh breadcrumbs, trim crusts from whole-wheat bread. Tear bread into pieces and process in a food processor until coarse crumbs form. To make fine breadcrumbs, process until very fine. To make dry breadcrumbs, spread coarse or fine breadcrumbs on a baking sheet and bake at 250°F until dry, about 10 to 15 minutes. One slice of bread makes about 1/2 cup fresh breadcrumbs or about 1/3 cup dry breadcrumbs. For store-bought coarse dry breadcrumbs we like Ian's brand, labeled “Panko breadcrumbs.” Find them at well-stocked supermarkets.
Variation: To make the sauce vegetarian, we like to use chicken-flavored vegetarian broth over regular vegetable broth for its hearty, rich flavor and pale yellow color. Look for “no-chicken” broth in the natural-foods section of well-stocked supermarkets.
