A Store Cupboard Habit That Pays for Itself

A 500g bag of dried beans is one of the quiet heroes of a well-run kitchen. Cook it through and you end up with roughly 1.2 to 1.4kg of tender, seasoned beans — the equivalent of four or five tins — for a fraction of the price, and with far better flavour and texture than anything that has sat in brine for a year. Cannellini, haricot, black turtle, butter beans, chickpeas, flageolet: they all work the same way.

The real advantage is not the money, though that helps. It is that a freezer full of cooked beans turns a vague weeknight into dinner. A handful goes into a soup, a stew, a salad, a curry, a traybake. Nothing to drain, nothing to rinse, no tin to open. You just reach in and cook.

Soak Overnight, and Brine If You Have Time

Cover the beans with at least three times their volume of cold water and leave them for eight to twelve hours — overnight is easiest. As they hydrate they will roughly double in size, so use a big bowl. If you have the forethought, make it a brine: about one tablespoon of fine salt per two litres of water. Brining seasons the beans from the inside and helps the skins stay intact, so you get fewer split, exploded beans in the pot. In warm weather, soak in the fridge.

• Short on time? Quick-soak instead: boil for two minutes, clamp on a lid, take off the heat and leave for one hour.
• Skip soaking altogether for red lentils, split peas and mung beans — they cook fast from dry.
• Hard water? Add half a teaspoon of bicarbonate of soda to the soaking water and again to the cooking pot. It softens the skins and cuts cooking time.
• Kidney beans need a hard boil for at least ten minutes before simmering, and should never go raw into a slow cooker — the temperature is too low to make them safe.

Simmer a Big Pot Properly

Drain and rinse the soaked beans, then cover with fresh water by about 5cm. Bring to a rolling boil and skim off the grey foam that rises. Now drop the heat to a bare simmer, lid slightly ajar, so the surface only trembles. A furious boil bashes the beans about and bursts their skins. Add a little salt now if you did not brine.

Timings vary, so treat these as guides and start checking early. Cannellini, haricot and black beans: 60 to 75 minutes. Butter beans: 75 to 90 minutes. Chickpeas: 90 to 120 minutes. Older beans take longer than fresh ones, and there is nothing you can do about that except taste as you go.

• Test by squeezing a bean between your fingers or blowing on it — it should collapse smoothly, with no chalky centre.
• Stir gently and only occasionally, and top up with hot water if the level drops below the beans.
• Keep acid out of the pot until the end. Tomatoes, wine and vinegar toughen the skins and stall softening.

Build Flavour While They Cook

This is where batch cooking earns its keep. Drop in a halved onion, a few bashed garlic cloves, a bay leaf, a sprig of thyme, a strip of kombu or a parmesan rind. These give the beans a savoury backbone without pushing them towards any one cuisine, so the same batch can become a Tuscan soup on Tuesday and a spiced stew on Friday. Hold back on strong spices, which are better added when you actually cook the dish.

Do not pour away the cooking liquid. It is mildly thick, faintly sweet and full of body — a brilliant base for soups and casseroles, or for cooking grains. Chickpea liquor, meanwhile, whips into aquafaba and makes a decent vegan meringue or a light binder for fritters.

Cool, Portion and Freeze Flat

Cool the beans quickly, ideally within 90 minutes: spread them on a tray or stand the pan in a sink of cold water. Portion into freezer bags at roughly one tin's worth, about 240g of drained beans, which is a sensible unit for most recipes. Flatten each bag to a centimetre or two thick, squeeze out the air, and label with the bean type and the date.

• In broth for soups, stews and casseroles; well drained for salads and grain bowls.
• Ice cube trays are perfect for small handfuls you can drop into a pan straight from frozen.
• Freeze flat first on a tray, then file the bags upright like records — they take up a fraction of the space.
• Best within three months, perfectly good up to six. Defrost overnight in the fridge, or drop them frozen into hot liquid.

Seasonal Ways to Use Your Stash

The freezer stash follows the year beautifully. In spring, fold white beans through a salad of young spinach, lemon and good olive oil, or mash them with herbs and spread on toast. Summer wants them cold: tomatoes, basil, red onion, a sharp vinaigrette. Autumn is for squash and sage with butter beans, cooked slowly until everything slumps together. Winter asks for casseroles, chillies and ribollita, where a bag of beans becomes a meal with whatever vegetables are lurking.

Beyond that, blitz them into hummus and dips, bind them into fritters with grated carrot and herbs, scatter them over traybakes, or stir them through curries in the last ten minutes. Once you have cooked one big pot on a quiet Sunday, the rest of the week cooks itself.
