Are tinned beans as good as dried beans?

This is a real trade-off rather than a snobbery question. Tinned beans are cooked in the tin under pressure, which is a perfectly good cooking method, and the main thing you lose is control.

Step by step

1. Compare on time and planning, not on effort.Dried beans need soaking the night before and one to three hours of cooking, but almost none of that is hands-on. Tinned need ninety seconds. If the difference matters, it is because you decided what to eat at six o'clock, not because dried beans are hard work.
2. Compare on cost properly.Weigh the dried beans, not the tins. Dried beans roughly double or triple in weight when cooked, so 500 g of dried gives you the equivalent of four or five tins. That is where the saving is, and it is substantial for anyone who eats pulses regularly.
3. Compare on texture.Home-cooked beans can be stopped exactly where you want them and hold their shape through a further braise. Tinned beans are cooked to a fixed point that suits mashing and blending but tends to collapse in a long simmer. If you want whole intact beans in a finished dish, dried wins clearly.
4. Compare on flavour.Cooking dried beans in seasoned water with an onion, a bay leaf, garlic and a strip of lemon peel gives you beans that taste of something. Tinned beans taste of bean and brine. Draining and rinsing them removes some of the tinny note; simmering them for ten minutes with aromatics helps more.
5. Check the salt and the tin.Salt content varies widely between brands — some are heavily salted and some are in plain water. Rinsing removes a large part of it. Tins with a plastic lining are standard in the UK; if you are concerned about bisphenols specifically, jars and cartons of cooked pulses are widely available.
6. Keep the cooking liquid from dried beans.It is savoury, gelatinous from the released starch, and it is the difference between a good bean dish and a great one. Use it as the liquid in the dish, in a soup, or to loosen a purée. Tinned bean liquid is thinner and saltier but aquafaba from chickpeas is genuinely useful.
7. Pick per dish.Blended or mashed — hummus, refried beans, bean soup, dips: tinned is fine, and for hummus specifically a tin with a pinch of bicarbonate simmered for ten minutes is excellent. Beans as the centrepiece — a bean stew, cassoulet, fresh borlotti, a bowl of beans with oil and salt: dried, cooked yourself, no contest.

Tips

• Do not drain a tin of beans down the sink out of habit if you are making a soup or stew — a little of the liquid adds body.
• Tinned kidney beans need no boiling; they are fully cooked. The hard-boil rule applies only to dried ones.
• Buying dried beans from a shop with high turnover matters more than the brand. Old beans are the single biggest cause of bad results.

Alternatives

• Dried beans, cooked in a batch and frozen: The best of both. Cook 500 g at a weekend, cool, and freeze in tin-sized portions in their liquid. You get dried-bean quality with tinned-bean convenience.
• Jarred beans: Spanish and Italian jarred beans — judión, cannellini, gigantes — are cooked far more gently than tinned and are outstanding. They cost more than tins and are worth it where the bean is the dish.
• Cartons and pouches: Cooked pulses in cartons or pouches, often with less salt and no tin. Texture sits between tinned and jarred.
• Pressure-cooked dried beans: Unsoaked dried beans in a pressure cooker take 25–40 minutes and remove the overnight planning entirely.
