How to plan meals for one person without waste

Cook in batches and eat the same base across several meals, buy loose and from the counter rather than in family packs, and freeze half of anything you cook the day you cook it — because the underlying problem for one person is that package sizes assume a household of four.

Why one person wastes more per head

Household waste per person falls as household size rises, and single-person households come out worst on that measure. The cause is not that people living alone are more careless. It is arithmetic.

Shops package for families. A bag of salad, a bunch of coriander, a loaf of bread, a 500g pack of mince and a 300g tub of cream are all sized for a household that will get through them in days. For one person the same package has to survive four times as long, and most of these items do not last four times as long.

At ReFED's estimate of about $762 per person per year, one person living alone is losing roughly that on their own, without the household-size effect working in their favour at all.

Cook once, vary the top

The instinct when cooking for one is to cook one portion. It is more work per meal, it leaves every package half-used, and it is the main reason people living alone default to convenience food.

Cook a base in quantity instead — a pot of dal, a ragù, a tray of roasted vegetables, a batch of rice — and vary what goes on top across the week. The same roasted vegetables become a grain bowl, then a soup, then a frittata filling. The base gets cooked once and the meals do not repeat.

Cooked leftovers hold 3 to 4 days in the fridge under USDA cold storage guidance, so a batch cooked Sunday genuinely covers to about Wednesday. Beyond that it needs to be in the freezer.

Freeze half on the day you cook it

Portion and freeze half of any batch at the moment it is cooked, not when you get bored of it on day three. Freezing at peak preserves what is there; freezing at the end preserves something already tired.

This is what turns batch cooking from a chore into a system. Four weeks in, the freezer holds a genuine choice of meals in single portions, which is the thing a person living alone actually wants on a Tuesday and the thing the shop cannot sell them affordably.

Buy in the format, not the multipack

The counters are the underused part of the shop for a single-person household. Butchers, fishmongers and deli counters will sell you one chicken thigh or a hundred grams of cheese, which no pre-packed shelf will. Loose produce beats bagged for the same reason: three peppers used beats a five-pack where two rot.

The per-kilo price is usually higher and the cost per thing eaten is usually lower, which is the number that matters.

Plan five meals, not seven

A week planned to the last slot leaves no room for the evening you eat out, work late, or simply do not want what Wednesday-you chose. Those evenings are where a plan for one falls apart and the ingredients bought for them go off.

Plan five, and let the leftovers and the freezer cover the rest. Under-planning is the single adjustment that makes meal planning for one survivable past the second week.

Counter and loose formats are only cheaper per thing eaten if you check, and our shelf prices for everyday groceries in Greece.

Common questions

Do people living alone waste more food?
Per person, yes. Household food waste per head falls as household size rises, largely because shops package and price for families while a single person has to make the same pack last four times as long.
How many meals should I plan when cooking for one?
Around five for a seven-day week. Leaving two evenings unplanned absorbs the nights you eat out or change your mind, which is where a fully booked plan for one usually breaks.
Is batch cooking worth it for one person?
It is the single most effective habit, provided half goes into the freezer on the day it is cooked. Cooked leftovers only hold 3 to 4 days in the fridge, so batch cooking without freezing just moves the waste to Thursday.
