A 15 oz can of chickpeas holds about 1 1/2 cups drained. That is the figure that matters in cooking, because almost every recipe that uses canned chickpeas tells you to drain and rinse them first. The can weighs 425 g in total, but a good part of that weight is the packing liquid, and once it is drained away you are left with about 1 1/2 cups of chickpeas. Undrained, the whole contents measure more — but nobody cooks with the liquid still in, except when they are deliberately saving it as aquafaba, the chickpea liquid that whips like egg white.
Chickpeas are one of the most useful canned foods to have in the cupboard, and the 1 1/2 cup figure is the key to using them well. Hummus recipes usually call for two cans, which is 3 cups drained. A salad for four uses one can. A curry for six uses two. If you know the drained yield, you can scale any chickpea recipe without opening a can to check, and you can shop accurately: a recipe calling for 3 cups of chickpeas needs two cans, not one, and finding that out halfway through cooking is the kind of delay that ruins a weeknight dinner.
Can of chickpeas conversion table
The table below shows the drained yield for fractions of a can and for multiple cans. All volumes are measured after draining and rinsing, which is how recipes expect you to use them.
| Amount | Cups (approx.) | Tablespoons | Fluid ounces |
|---|---|---|---|
| 1/4 can | 0.38 cups (about 3/8 cup) | 6.0 tbsp | 3.0 fl oz |
| 1/2 can | 0.75 cups (about 3/4 cup) | 12.0 tbsp | 6.0 fl oz |
| 3/4 can | 1.12 cups (about 1 1/8 cups) | 18.0 tbsp | 9.0 fl oz |
| Full can | 1.50 cups (about 1 1/2 cups) | 24.0 tbsp | 12.0 fl oz |
| 2 cans | 3.00 cups | 48.0 tbsp | 24.0 fl oz |
The can weighs 425 g in total (15 oz), but that includes the packing liquid. The drained chickpeas weigh less — the exact drained weight varies by brand and is not published as a standard figure, so measure by volume after draining rather than by weight.
Worked examples
Hummus for a party
A hummus recipe for a party calls for 3 cups of drained chickpeas, blended with tahini, lemon juice, garlic and olive oil. Two 15 oz cans give you exactly 3 cups drained, so open both, drain and rinse them, and set aside a few whole chickpeas for garnish. Blend the rest with 1/3 cup of tahini, the juice of one lemon, one garlic clove and 1/4 cup of olive oil, adding ice water a tablespoon at a time until the texture is silky. The hummus keeps for five days in the fridge, and the recipe scales cleanly: one can makes a small batch for two people.
A chickpea salad for four
A Mediterranean chickpea salad for four people uses one can — 1 1/2 cups drained — tossed with chopped cucumber, red onion, cherry tomatoes, feta and a lemon and olive oil dressing. Drain and rinse the chickpeas well, because the packing liquid is starchy and salty and would make the salad cloudy and over-seasoned. Let the salad sit for fifteen minutes before serving so the chickpeas absorb the dressing. One can is the right amount for four as a side dish; as a main course for four, use two cans and double the vegetables.
A chickpea curry for six
A chickpea curry for six people calls for 3 cups of drained chickpeas, simmered in a spiced tomato and coconut sauce. Two cans give you exactly 3 cups. Add the chickpeas after the sauce has simmered for ten minutes, then cook for another fifteen so they absorb the flavours. If you are cooking for three instead, use one can and halve the sauce — the chickpeas are the backbone of the dish, so getting their quantity right matters more than anything else in the pot.
How the figure is worked out
There is no weighing involved in the headline answer — it is arithmetic on two published numbers. The package weight is a standard 15 oz can of chickpeas, drained and rinsed. The cup weight comes from the ingredient table, and dividing one by the other gives the cups in the package. That is also why the answer is approximate: scoop a cup differently and the grams per cup change, so the cups per bag move with it. For anything where the amount truly matters, weigh the ingredient instead of counting cups.
Practical guidance
Drain and rinse unless the recipe says otherwise. The packing liquid is cloudy, starchy and salty, and it will change the flavour and texture of most dishes. Rinsing under cold water for thirty seconds is enough. The exception is aquafaba: the liquid in a can of chickpeas whips into stiff peaks like egg white and is used in vegan meringues and mousses. If you want to save it, drain the can over a bowl instead of into the sink — one can gives you the liquid from that can, and it keeps for a few days in the fridge. Do not try to measure aquafaba by the cup for a recipe that expects it by the can; just use the liquid from the number of cans the recipe specifies.
Chickpeas are not in the ingredient density table, so there is no grams-per-cup figure for them here — measure by volume after draining. Check the label for added salt: most canned chickpeas are packed in salted water, and rinsing removes much of it, but low-sodium cans are available if you are watching salt. Store leftovers in a sealed container in the fridge for three to four days, or freeze them in a bag for up to three months. Frozen chickpeas thaw quickly in a pan of sauce or under cold running water.
Frequently asked questions
How many chickpeas are in a can?
About 1 1/2 cups drained, from a standard 15 oz can. The count varies because chickpeas are different sizes, but the volume is consistent enough that recipes are written around it. If you are counting individual chickpeas for a garnish, expect roughly 200 to 250 per can — but nobody cooks that way.
Should I rinse canned chickpeas?
Yes, for almost everything. Rinsing removes the starchy, salty packing liquid and gives you a cleaner flavour and a better texture. The only time to skip rinsing is when the recipe specifically uses the packing liquid — for aquafaba, or for a stew where the starch helps thicken the sauce.
What is aquafaba and how much is in a can?
Aquafaba is the liquid in a can of chickpeas, and it whips like egg white. One 15 oz can yields the liquid from that can — drain it into a bowl instead of the sink to save it. It keeps for a few days in the fridge and can be frozen in ice-cube trays. It is used in vegan meringues, mousses and mayonnaise.
Can I use dried chickpeas instead of canned?
Yes, but they need soaking and long cooking, and the conversion is not a simple cup-for-cup swap — dried chickpeas roughly double in volume when cooked, and the exact yield depends on the variety and soaking time. For a recipe that calls for one can, cook a batch of dried chickpeas and measure out 1 1/2 cups after cooking. Canned chickpeas are far more convenient for weeknight cooking.
How long do opened canned chickpeas keep?
Three to four days in the fridge in a sealed container, or up to three months in the freezer. Transfer them out of the can as soon as you open it, and rinse before storing if you have not already. Frozen chickpeas can go straight into a hot sauce or curry without thawing.
