Assigning a specific dish to every night of the week is the version of meal planning that most people try first and abandon fastest. It fails not because you lack discipline but because it has no tolerance for a changed evening.
Plan shapes, not recipes
Decide the week as categories: two pasta or rice nights, two tray-bake nights, one soup, one leftovers night, one night out or takeaway. That is a plan you can hold in your head. Then shop for the shapes. The exact dish gets decided at six o’clock, when you know what the day was actually like.
Build in the leftovers night on purpose
Every week produces odds and ends. If there is no night designated to eat them, they sit until they are thrown away. Thursday or Friday works best: enough has accumulated to make a meal, and nobody wants to cook properly by then anyway.
Shop for five nights, not seven
Buying for every night guarantees waste, because a week always contains an unexpected meal out, a late night or a day someone is not hungry. Five dinners’ worth of fresh ingredients plus a stocked cupboard covers seven nights. The cupboard absorbs the surprises.
Cook once, eat twice, on purpose
Double the batch of anything that reheats — stew, sauce, roast vegetables, rice — and the second night costs ten minutes instead of forty. This is not the same as eating the same meal twice. Yesterday’s roast vegetables become today’s soup, omelette filling or grain bowl.
Plan the shape of the week, leave the dish until the evening, shop for five nights and cook double twice. That plan survives a Wednesday that goes wrong.
