A cup of panko is 50 g — the King Arthur Baking figure, measured spooned and levelled. Light, airy Japanese breadcrumbs; very low density per cup. It is used for crispy coatings for fried and baked foods. It is the lightest ingredient on this page by a wide margin at 50 g per cup, which means a recipe that needs 100 g of it asks for two full cups, and a cook who swaps it for ordinary breadcrumbs cup-for-cup ends up with less than half the weight and a coating that barely covers the food. This guide covers the weight of panko in every measure you will use — cups, tablespoons and teaspoons — how to measure it correctly, what to use instead when you run out, and how to store it. All weights on this page are approximate; verify with a kitchen scale when the recipe matters.
Panko: weight and measurement table
The table below gives the weight of Panko in every measure you will use, from a teaspoon up to 2 cups, all derived from the King Arthur Baking figure of 50 g per cup, spooned and levelled. Every figure is approximate — spooned and levelled is a technique, not a machine setting — so when the recipe matters, weigh the ingredient on a kitchen scale instead.
| Amount | Weight (approx.) |
|---|---|
| 1 teaspoon | 1 g |
| 1 tablespoon | 3.1 g |
| 1/4 cup (4 tbsp) | 12.5 g |
| 1/3 cup | 16.7 g |
| 1/2 cup (8 tbsp) | 25 g |
| 3/4 cup (12 tbsp) | 37.5 g |
| 1 cup (16 tbsp) | 50 g |
| 2 cups | 100 g |
| 100 g | 2 cups |
There are 3 teaspoons in a tablespoon and 16 tablespoons in a cup, so you can move between any of these measures by multiplying or dividing. If a recipe calls for 100 g and you only have measuring cups, that is about 2 cups. Keep the cups to grams converter open while you cook and you will never need to do the arithmetic in your head.
What is Panko?
Light, airy Japanese breadcrumbs; very low density per cup. Panko is used for crispy coatings for fried and baked foods. The ingredient is a familiar one in most kitchens, but it is worth knowing what it actually is before you measure it, because the form it comes in decides how it behaves in a recipe. Panko as sold is the form the weight on this page refers to: 50 g per cup, spooned and levelled, from King Arthur Baking. If you buy it in a different form — chopped, ground, toasted, sweetened or unsweetened — the weight per cup changes, sometimes by a lot, so weigh the ingredient in the form the recipe asks for, or weigh it before you change its form. That single habit, weighing before chopping, grinding or toasting, is what keeps the recipe consistent from one bake to the next.
How to measure Panko
Spoon the panko lightly into the measuring cup or spoon, then level the top with the back of a knife. Do not scoop the measure straight from the bag or the jar, because scooping packs the ingredient down and adds weight with every spoonful. Do not press it down or shake the measure to settle it, because that packs it too. The spooned and levelled method is a technique, not a machine setting, so two people measuring the same ingredient can still differ by a few grams, which is why the figures on this page are approximate. When the recipe matters, weigh the panko on a kitchen scale instead: put the bowl on the scale, press tare, and add the panko until the scale reads the weight you need.
How to store Panko
Airtight container, cool and dry, up to 6 months. That storage advice is worth following, because panko goes stale faster than most cooks expect, and stale panko will spoil a whole batch of baking. Keep it sealed, because air and moisture are what make it go stale, and keep it away from strong smells, because it absorbs odours from the cupboard. Check the ingredient before you use it: smell it, taste a little, and look at it. If it smells sharp, stale or off, or if it has changed colour or texture, replace it rather than risking a recipe on it. A small amount of fresh panko is always better than a large amount of stale panko, and the cost of replacing it is far less than the cost of a ruined bake.
What to use instead of Panko
If you run out of panko, the closest swaps are Breadcrumbs at 112 g per cup. Swap by weight, not by volume, because the cup weights differ, and a volume swap gives the wrong amount. Each substitute changes the flavour a little, so choose the one that suits the dish: a mild substitute for a delicate bake, and a stronger one where the flavour can carry it. Taste the finished dish before serving, because a substitute that works in a salad may not work in a cake, and the other way round.
Worked examples: Panko in real recipes
1. A crispy fried chicken for a family dinner
A fried chicken for four uses 16 tablespoons of panko, about 50 g, to coat the chicken after flour and beaten egg. The panko gives the chicken a light, shatteringly crisp crust that ordinary breadcrumbs cannot match, and the weight is what decides the coverage: too little panko and the coating is patchy, too much and it turns thick and heavy. Press the crumbs on firmly, chill the coated chicken for thirty minutes, and fry it in hot oil so the coating sets quickly and stays crisp.
2. A panko topping for macaroni cheese
A macaroni cheese for six uses 8 tablespoons of panko, about 25 g, scattered over the top with a little grated cheese before baking. The panko turns golden and crisp in the oven, and the weight is what decides the crunch: too thick a layer and the crumbs underneath stay soggy, too thin and the topping disappears. Scatter the panko loosely over the top, drizzle it with a little melted butter, and bake the dish until the topping is golden and the sauce is bubbling.
3. A tonkatsu for a Japanese dinner
A pork tonkatsu for two uses 12 tablespoons of panko, about 37.5 g, to coat the pounded pork after flour and beaten egg. The panko is what makes tonkatsu different from an ordinary schnitzel: the large flakes give a lighter, airier crust that stays crisp even under the sauce. Press the crumbs on firmly, fry the pork in hot oil until the crust is golden, and rest it for a few minutes before slicing, so the coating stays crisp and the meat stays juicy.
Why the weight of Panko matters
Panko matters by weight because it is so light that the cup measure is almost useless. The crumbs are large, flaky and full of air, so a cup holds only 50 g, against 112 g for ordinary breadcrumbs, and the same cup can hold very different amounts depending on how the flakes settle. In a coating, the panko content decides whether the food is evenly covered or patchy, and a 20 g error is the difference between a crisp crust and a bare spot. Panko gives a crunchier, lighter coating than ordinary breadcrumbs, because the large flakes stay crisp and absorb less oil, which is why it suits fried chicken and tonkatsu. Weighing the panko is the only reliable way to get the same coating twice, and it also matters because panko is more expensive than ordinary breadcrumbs, so a recipe that says a cup can hide a wide range of actual amounts.
The King Arthur Baking figure, and how it was measured
The King Arthur Baking figure for panko is not disputed: 50 g per cup, spooned and levelled, is the accepted value, and other sources agree within a few grams. Small differences between brands and batches are normal, because natural ingredients vary, but the variation is small enough that the figure on this page is a reliable guide for everyday cooking. The figure on this page, 50 g per cup, was measured spooned and levelled, which is the standard method for this kind of ingredient. If you measure it differently — scooping instead of spooning, packing instead of levelling, or measuring after chopping — the weight changes, and the recipe changes with it. The source matters too: King Arthur Baking is the reference used throughout this site, because its figures are consistent and widely used in baking, and the USDA figures are used where King Arthur does not publish one. When two sources disagree, this site says so, and the figure given is the one judged most reliable for everyday cooking.
Common mistakes with Panko
The most common mistake is swapping panko for ordinary breadcrumbs cup-for-cup without adjusting: panko is less than half the weight, so the same cup holds far less coating. Swap by weight instead. The second mistake is coating food in panko without pressing it on firmly, so the flakes fall off in the pan. Press the crumbs on, then chill the coated food for thirty minutes before cooking. The third mistake is frying panko-coated food in oil that is not hot enough, which makes the coating absorb oil and turn soggy instead of crisp. Finally, do not store panko in a damp place, because the flakes go soft and lose their crunch; a sealed jar in a cool cupboard keeps them crisp for months.
Frequently asked questions
How many grams is 1 cup of panko?
One cup of panko weighs about 50 g, spooned and levelled, using the King Arthur Baking figure. That is for panko as sold, loosely spooned into the cup, and the weight is less than half that of ordinary breadcrumbs at 112 g per cup, because the flakes are large and full of air. The figure is approximate, so verify with a kitchen scale when the recipe matters.
How many tablespoons is 100 grams of panko?
100 grams of panko is about 32 tablespoons, spooned and levelled, because one tablespoon weighs about 3.1 g. That is two full cups, which surprises people, but panko is mostly air between the flakes. Weigh it on a scale rather than counting out thirty-two spoonfuls.
What is the difference between panko and breadcrumbs?
Panko is made from crustless white bread baked with an electric current, which gives large, airy flakes that stay crisp and absorb less oil. Ordinary breadcrumbs are finer, denser and heavier, at 112 g per cup against 50 g for panko. Panko gives a lighter, crunchier coating, while breadcrumbs give a denser, more even coating and bind better in meatballs and stuffing.
Can I use breadcrumbs instead of panko?
Yes, but the result is different: breadcrumbs are heavier and finer, so the coating is denser and less crisp, and it absorbs more oil. By weight the swap is simple, but the texture changes, and for fried chicken and tonkatsu, panko gives a noticeably lighter, crunchier crust. For meatballs and stuffing, fine breadcrumbs bind better than panko.
How should I store panko?
Keep it in an airtight container in a cool, dry place for up to 6 months. Damp makes the flakes go soft and lose their crunch, and warmth shortens their shelf life. If the panko smells stale or feels soft, replace it, because soft panko will not give a crisp coating.
