How Many Grams in a Cup of Breadcrumbs?

Dry breadcrumbs bind meatballs, coat cutlets, and top casseroles. One US cup of plain dry breadcrumbs weighs approximately 108 grams when lightly spooned and leveled. Panko Japanese breadcrumbs are flakier and lighter—about 60 to 70 grams per cup—so this conversion targets standard American fine dry breadcrumbs unless specified otherwise.

Spoon breadcrumbs into a measuring cup without compacting for accurate volume, or weigh 108 grams for dry fine crumbs. Fresh soft breadcrumbs from blended bread weigh roughly 120 grams per cup and behave differently in recipes—always note fresh versus dry in recipe conversion.

Errors include using Panko weight for standard breadcrumb recipes, producing insufficient coating. Substituting cracker crumbs or cornflake crumbs without adjusting weight changes salt and fat content. Packing breadcrumbs like brown sugar doubles density and makes meatballs dense and dry.

Store dry breadcrumbs sealed at room temperature for six months or freeze for a year. Make homemade crumbs by drying bread in a low oven and pulsing in a food processor. Substitute Panko with lighter volume by weight, or crushed crackers at roughly 100 grams per cup depending on cracker density.

Dry breadcrumbs at 108 grams per cup coat cutlets and bind meatballs where too many crumbs absorb moisture and produce dense texture. Panko conversions differ intentionally—do not assume 108 grams when a Japanese recipe specifies panko cups. Fresh breadcrumbs from pulsed sandwich bread weigh more and behave differently in panades. When toasting crumbs for topping casseroles, toast after measuring dry weight so evaporation does not skew the amount mixed with butter or oil for crunchy gratin layers.

Combine weighed breadcrumbs with melted butter for gratin toppings—108 grams dry crumbs plus butter by weight toasts evenly without soggy patches from butter measured by eye over unweighed crumbs sitting loose in the measuring cup before baking the hot gratin dish.
