1/2 Cup Breadcrumbs in Grams
1/2 cup of breadcrumbs weighs 56 g (spooned and levelled, King Arthur Baking). Fine, dry crumbs from baked bread. All the figures on this page are approximate conversions based on the King Arthur Baking value, so when a recipe really matters, verify with a kitchen scale. Breadcrumbs are the ingredient that turns a soft mixture into something crisp, which is why a half cup of them is the amount that coats a tray of chicken, binds a meatloaf or tops a gratin, and why the weight matters: fresh, dried and panko crumbs are three different ingredients by the cup.
Why half a cup of breadcrumbs is a useful amount
Half a cup of breadcrumbs is the amount that serves one or two people, fills a loaf of bread, or thickens a batch of soup, and it is an amount where the cup is surprisingly unreliable. Grains and flakes vary in size, settle in the bag, and pack differently when they are whole, rolled, cut or ground, so a level half cup can weigh several grams more or less depending on the form. Breading, meatballs, stuffing and gratins. The table below is built from the published King Arthur Baking weight for breadcrumbs measured spooned and levelled, so you can weigh a batch once and repeat it exactly.

The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of breadcrumbs weighs about 7 g, and one teaspoon about 2.3 g. A cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded to one decimal place. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.
How the weight was measured
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight.
The source for the 112 g figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
Worked examples
A tray of breaded chicken
A tray of breaded chicken for a family uses 1/2 cup of breadcrumbs, which is 56 g, seasoned with salt, pepper and herbs. The crumbs have to be weighed before seasoning, because the seasoning adds weight and the coating has to be even. Weighing 56 g keeps the coating crisp without being patchy, and the chicken should be patted dry first, or the crumbs slide off in the pan.
A meatloaf for a family dinner
A meatloaf for a family dinner calls for 1/2 cup of breadcrumbs, which is 56 g, mixed into the meat with egg and onion. The crumbs absorb the juices as the loaf cooks, so their weight decides whether the meatloaf is tender or dense. Weighing 56 g keeps the loaf right, and the mixture must be mixed only until combined, or the loaf turns tough.
A gratin topping for a dinner party
A gratin for a dinner party is topped with 1/2 cup of breadcrumbs, which is 56 g, tossed with butter and parmesan. The crumbs crisp in the oven and protect the sauce below, so their weight decides whether the topping is golden or patchy. Weighing 56 g keeps the topping even, and the crumbs should go on just before baking, or they absorb the sauce and turn soggy.
When this conversion matters most
This conversion matters most when a grain is the backbone of the dish. In a pilaf, the weight of breadcrumbs against the water decides whether the grains stay separate or turn to mush; in bread, it decides how much water the dough needs; in a coating, it decides whether the crust is crisp or patchy. A cup measure hides all of that behind how settled the bag is, so two cooks following the same recipe with cups can end up with different results. Weighing removes the guesswork and tells you exactly how much of a staple a recipe really needs, which also makes shopping and costing far easier.
Common mistakes with breadcrumbs
- Mixing grain forms. Whole, rolled, cut and ground forms of the same grain weigh differently per cup, so a half cup of one is not a half cup of another. Use the weight for the exact form the recipe calls for.
- Scooping from a settled bag. Grains settle in storage, so a scooped half cup from the bottom of the bag weighs more than a spooned one from the top. Stir the bag first, then spoon and level.
- Measuring cooked instead of dry. Cooked grains absorb water and weigh two to three times as much as dry ones. Always weigh grains dry unless the recipe explicitly says cooked.
- Guessing the water ratio. A cup of grain and a cup of water are not a ratio you can scale by eye: the ratio is by weight. Weigh the grain, then measure the water to match.
Storage and handling
Airtight container, cool and dry, up to 6 months. Keeping breadcrumbs stored properly also keeps its weight per cup stable: an ingredient that has absorbed moisture from the air weighs more per cup than a dry one, so a sealed container is not just about freshness, it is about measurement accuracy too. If a bag has been open for months in a humid kitchen, the first thing to do before a precise bake is to weigh the ingredient rather than trusting the cup.
Frequently asked questions
How many grams is 1/2 cup of breadcrumbs?
1/2 cup of breadcrumbs weighs 56 g, measured spooned and levelled according to King Arthur Baking. That is the figure to use when converting a recipe from cups to grams, and it is the value the conversion table on this page is built on.
How do I measure breadcrumbs without a scale?
Spooned and levelled means spooning the ingredient into the measuring cup until it is heaped, then sweeping a straight knife across the top to level it off. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. That gives the closest result to 56 g per half cup, but it is still an estimate: the honest answer is that a scale is the only way to know the exact weight, and a basic digital kitchen scale costs less than a bag of good flour.
Does breadcrumbs always weigh the same per cup?
No. Brand, grind, moisture and how settled the container is all shift the weight by a few grams, and for some ingredients the swing can be much larger. The 112 g figure is the standard King Arthur Baking value for breadcrumbs measured spooned and levelled, and it is the right default, but when a recipe is precise, weigh the ingredient and trust the scale over the cup.
Can I use the same conversion for a different brand of breadcrumbs?
Yes, as a starting point. The 112 g figure is a standard average for breadcrumbs, and most brands sit within a few grams of it. If you cook with one brand all the time, weigh one cup of it once and note the number on the bag, and you will have a conversion tuned to your own kitchen.
Are fresh breadcrumbs the same weight as dried breadcrumbs?
No. Fresh breadcrumbs are soft and moist, so a half cup of them weighs more than a half cup of dried crumbs, which is 56 g. The two cannot be swapped cup for cup: fresh crumbs absorb more liquid and give a softer coating, while dried crumbs give a crisper one. If a recipe calls for dried breadcrumbs, weigh the dried kind, and if you only have fresh, dry them in a low oven first and weigh them after.
How should I store breadcrumbs?
Airtight container, cool and dry, up to 6 months. Good storage keeps the ingredient fresh and keeps its weight per cup consistent, because moisture absorbed from the air adds grams that the recipe did not ask for.
