Batch cooking that works

Batch cooking is widely recommended and frequently abandoned, generally because the wrong things were cooked or too much was attempted at once.

What actually works in batches

The dishes that improve or hold well.

Braises and stews, which improve after a day and freeze well.

Ragù and meat sauces, which are useful in several forms.

Soups, particularly those thickened with pulses or vegetables rather than dairy.

Curries and chilli.

Pulses, cooked from dried in quantity and frozen in portions, which is substantially cheaper than tinned and better.

Stock, reduced and frozen.

Roasted vegetables, which keep several days refrigerated and go into several different meals.

Grains, cooked and cooled quickly, which keep a few days and freeze.

What does not

Worth avoiding.

Anything fried, which loses texture.

Pasta cooked into a dish, which continues absorbing and becomes soft.

Potato in liquid dishes, which becomes grainy after freezing.

Dairy-thickened sauces, which separate.

Salads and anything intended to be crisp.

Fish, which is generally better cooked fresh and quickly.

The component approach

Which works better than cooking complete meals.

Rather than making five identical portions of one dish, cook components that combine differently.

A base of onions, garlic and tomatoes becomes a pasta sauce, a curry base, a soup or a braise depending on what is added.

Roasted vegetables go into a grain bowl, a frittata, a soup or a salad.

Cooked pulses go into several things.

Which avoids the principal complaint about batch cooking, which is eating the same thing four times.

The practical session

How to organise it.

Two to three hours produces most of a week's cooking for a household.

Start whatever takes longest — the oven, anything braising — and work on shorter tasks while it proceeds.

Use the oven fully, since roasting several trays costs no more energy than one.

Chop everything for all dishes at once rather than dish by dish.

And clear as you go, since the end of a batch session with an unusable kitchen is what stops people repeating it.

Cooling and storage

Where food safety matters.

Cool cooked food quickly rather than leaving it out — dividing into shallow containers, standing in cold water, or spreading on a tray all speed it.

Refrigerate or freeze within a couple of hours.

Rice specifically requires prompt cooling and thorough reheating, since improperly stored cooked rice is a recognised source of food poisoning.

Label everything with contents and date.

And reheat thoroughly, to steaming throughout, rather than warming.

The economics

Where the saving actually is.

Buying larger quantities of the base ingredients, which are generally cheaper per unit.

Using cheaper cuts, which suit long cooking and which are substantially less expensive than quick-cooking ones.

Cooking pulses and grains from dry rather than buying prepared.

Reducing waste, since ingredients bought for a batch are used rather than deteriorating.

And reducing the takeaway and convenience food that a tired evening with nothing prepared otherwise produces, which for most households is the largest saving.

Starting realistically

Where people fail.

Attempting a full week of meals on the first attempt generally produces an exhausting afternoon and no repeat.

Cooking double whenever you cook something suitable, and freezing half, requires no additional session at all and builds a stock within a few weeks.

Which is the version that people actually sustain, and it achieves most of the benefit.

Cooling and storing safely

The part that batch cooking makes more important, since larger volumes cool more slowly.

Food should be cooled quickly and refrigerated or frozen within a couple of hours, and a large pot left on the hob overnight sits for hours in the temperature range where bacteria multiply fastest.

The practical measures: divide into shallow containers rather than cooling one deep pot; stand the pan in cold water; and leave containers uncovered until cool, then cover.

Label everything with contents and date, since unlabelled frozen containers become a category of their own.

Reheat thoroughly rather than merely warming, and only once.

And take particular care with rice, which should be cooled fast, refrigerated promptly and reheated once only.
