Once you know the soak, dried beans are cheaper, better, and honestly easier than the tin.
The tin is fine. Dried is better.
Nobody is here to take your tinned chickpeas away. On a Tuesday night, a tin is exactly right — rinse, drain, done. But if you've ever wondered why a bowl of beans at a good restaurant tastes so much more complete, so much silkier and more flavourful than what comes out of your weekly can, the answer is almost certainly dried beans cooked from scratch. And once you've done it a few times, you'll find it barely qualifies as cooking.
The case starts with cost. Dried beans are routinely three to five times cheaper per portion than their tinned equivalents. A 500g bag of dried borlotti or cannellini will yield roughly the equivalent of four to five tins — at a fraction of the price. For anyone cooking on a real budget, that gap matters. But cost is only the beginning.
The flavour difference is significant and largely comes down to the cooking liquid. When you cook dried beans from scratch, you end up with something extraordinary: a silky, starchy, cloudy broth that is deeply savoury and entirely your own. Tinned beans come in a thin, metallic liquid almost everyone rinses away. Homemade bean broth — known in Italian cooking as acqua di cottura, the cooking water — is itself worth keeping. Stir it into soups, loosen a stew, use it to thicken a sauce. It's something a tin simply cannot give you.
The texture wins too. Dried beans cooked well are creamy at the centre, with just enough skin to give you something to bite. They hold their shape while still yielding. Tinned beans, which are cooked under high pressure and often in large batches, tend toward mushiness at the edges.
| Dried, from scratch | Tinned | |
|---|---|---|
| Cost per portion | 3–5× cheaper | the baseline |
| The liquid | a silky, savoury broth worth keeping | thin and metallic; everyone rinses it |
| Texture | creamy centre, skin with some bite | soft, mushy at the edges |
| Effort | 30 seconds, then waiting | rinse and drain |
The soak — and why it's not a burden
Here's where people get anxious. The soak. It sounds like planning, and planning sounds like effort. But the soak itself takes about thirty seconds of your time — it's just waiting after that.
The standard method: tip your dried beans into a large bowl, cover generously with cold water (they'll swell considerably), and leave them for eight to twelve hours. Overnight is the classic move, and it genuinely is the path of least resistance — you do nothing before bed, and in the morning the hard work is done. Drain them, rinse them, and they're ready to cook.
Why soak at all? Dried beans contain oligosaccharides — complex sugars that our digestive systems can't fully break down, which is what causes the bloating many people associate with beans. Soaking draws these out into the water, which you discard. A long soak also reduces cooking time substantially, and helps the beans cook more evenly throughout.

If you forget to soak overnight, the quick soak works: cover beans with cold water in a pot, bring to a boil, cook for two minutes, then remove from the heat and leave to sit for an hour. Drain, rinse, and continue. It's not quite as thorough, but it does the job.
One note on salt: there is a long-standing myth that salting beans during cooking toughens them. Food science has largely debunked this. Salt your cooking water as you would pasta water — modestly but meaningfully — and the beans will be seasoned all the way through, not just on the surface.
Cooking them well, and what to do next
Once soaked and rinsed, cover your beans with fresh cold water by a good few centimetres, bring gently to a boil, skim off any foam that rises (it's harmless but a little bitter), then reduce to a steady simmer. The time varies by bean: lentils need no soaking and cook in twenty to thirty minutes; small white beans and puy lentils are fairly quick; chickpeas and large butter beans can take an hour and a half or more. The only test that matters is taste — fish one out and eat it.
A simple approach that elevates everything: cook your beans with a halved onion, a few garlic cloves, a bay leaf, and a glug of olive oil in the water. You don't need to eat any of these aromatics, but they quietly improve both the beans and the broth over the cooking time.
When they're done, let them cool in their liquid if you have time — they absorb more flavour as they rest, and they're less likely to split. Store beans in their broth in the fridge for up to five days, or freeze them flat in freezer bags with enough liquid to cover.
Where to go from here is almost the fun part. Cooked cannellini stirred into a brothy pot of greens and good olive oil is one of the genuinely perfect simple suppers. White beans mashed roughly on toast, with lemon and herbs, turns an overlooked cupboard staple into something you'd order at a café. Chickpeas roasted until crisp, black beans in tacos, borlotti in a market minestrone — the range is extraordinary.
