1 Cup Panko in Grams

1 cup of panko weighs 50 g (spooned and levelled, King Arthur Baking). Light, airy Japanese breadcrumbs; very low density per cup. 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.

Why weighing panko beats measuring it in cups

Panko is the lightest cup measure on this site at just 50 g per cup, and the lightness is the whole point of it. Panko is made from crustless white bread baked with an electric current, which produces large, airy flakes that stay crisp instead of absorbing oil. Those flakes are mostly air, so a cup of panko weighs less than half as much as a cup of fine breadcrumbs at 112 g, and the difference is not a rounding error: it is the difference between a light, shattering crust and a heavy, dense one.

The weight matters because cooks routinely substitute panko for breadcrumbs cup for cup, and the swap fails. A recipe that calls for a cup of breadcrumbs and gets a cup of panko will have less than half the crumb weight, and the coating will be thin, patchy and barely there. The fix is to use about twice the volume of panko, or to weigh the same weight and accept that the volume will be much larger. Either way, the cup measure is misleading for panko, and the scale is the only reliable tool. Panko also absorbs less oil than fine breadcrumbs, so the finished coating is crisper and less greasy, which is why it is the first choice for tonkatsu, fried chicken and baked fish.

2 cups 100 g 32
3 cups 150 g 48
4 cups 200 g 64

One tablespoon of panko weighs about 3.1 g, since a cup is 16 tablespoons. That is useful when a recipe calls for a spoonful or two rather than a whole cup, though 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.

Worked examples

Tonkatsu for four

Tonkatsu for four people uses about 1 cup of panko, which is 50 g, to coat four pork cutlets. Set up a breading station with flour, beaten egg and the panko, and weigh 50 g so the coating is even. Press the panko onto the pork firmly, let the cutlets rest for ten minutes, then fry until golden and crisp. The panko will puff slightly and stay crisp, which is the point of using it.

Baked fish fingers for a family dinner

Fish fingers for a family dinner use about 1 1/2 cups of panko, which is 75 g, to coat strips of white fish. Weigh 75 g and press the panko onto the fish firmly, then bake on a hot tray with a little oil until golden. Panko gives a lighter, crispier coating than fine breadcrumbs, and it stays crisp in the oven where fine crumbs can go soggy.

Panko-crusted chicken for six

Chicken for six people uses about 2 cups of panko, which is 100 g, seasoned with salt, pepper and paprika. Weigh 100 g and mix in the seasoning, then coat the chicken pieces and bake or fry until crisp. Because panko is so light, two cups looks like a lot of crumbs, and cooks who measure by eye tend to use too little: weigh it and the coating will be even.

How the weight was measured

The figure on this page comes from King Arthur Baking, measured spooned and levelled unless the method line says otherwise. Spooning means filling the cup with a spoon rather than plunging the cup into the bag, and levelling means sweeping a knife across the rim. Scooping packs the ingredient down and can add a fifth or more to the weight, which is why two bakers following the same cup-based recipe can get visibly different results.

Confidence in this value is high. That reflects how consistent the ingredient is from brand to brand: a uniform, factory-packed ingredient is more predictable than a fresh, variable one. Even a high-confidence figure is still an approximation, because moisture, grind size and settling all shift the weight a little. Treat the grams on this page as a reliable starting point and check with a scale when the recipe is fussy, expensive, or being made for the first time.

Practical guidance

Store panko in an airtight container in a cool, dry place for up to 6 months, because it goes stale and picks up kitchen smells quickly. Do not press panko down in the cup when measuring, because the flakes crush and the weight changes: spoon it in loosely and level the top. Season the panko before using it, because plain panko is bland, and mix in herbs, spices or grated cheese for extra flavour. For the crispiest coating, let the breaded food rest for ten minutes before cooking so the coating sets, and do not overcrowd the pan, because the temperature drops and the panko absorbs oil instead of crisping. If you do not have a scale, remember the 50 g figure is approximate and that panko is mostly air, so a cup measure is at its least reliable here.

Common mistakes with grains and crumbs

The most common mistake is measuring grains and crumbs by scooping the cup through the bag. Scooping compresses the contents and a cup can easily hold a fifth more than a spooned cup, which changes the liquid balance of a porridge, a stuffing or a coating. Spoon and level, or weigh. The second mistake is confusing cooked and uncooked weights: a cup of dry barley and a cup of cooked barley are entirely different ingredients, and recipes that mix them up fail badly. This page covers the dry ingredient only. The third is storing crumbs and grains in the open bag: they go stale and pick up kitchen smells within weeks, so decant into an airtight jar. Finally, do not substitute panko for fine breadcrumbs cup for cup: panko is far lighter, so the same volume weighs less than half as much and the coating comes out thin and patchy.

Frequently asked questions

How many grams is 1 cup of panko?

1 cup of panko weighs 50 g when spooned and levelled, according to King Arthur Baking. The figure is approximate, because the large airy flakes settle differently, so verify with a kitchen scale when it matters.

Why is panko so much lighter than breadcrumbs?

Because panko is made from crustless white bread into large, airy flakes that are mostly air, while fine breadcrumbs are dense crumbs that pack tightly. A cup of panko is 50 g and a cup of fine breadcrumbs is 112 g, so the two are not interchangeable by volume.

How much panko replaces 1 cup of breadcrumbs?

About two cups of panko, or 100 g, replaces one cup of fine breadcrumbs at 112 g. Weigh the panko rather than measuring by volume, because the flakes are mostly air and a cup measure is unreliable.

Does panko absorb less oil than breadcrumbs?

Yes. Panko flakes stay crisp and absorb less oil than fine breadcrumbs, which is why the coating is lighter and crunchier. That makes panko the better choice for fried foods where a greasy coating is the risk.

Can I make panko at home?

You can approximate it by blitzing crustless white bread into coarse flakes and drying them in a low oven, but true panko is made with a special baking method that produces larger, airier flakes. Shop-bought panko is inexpensive and more consistent.
