Sunday afternoon you made a vast pot of chilli. Four tubs, lined up on the counter, and the warm feeling of a week already handled.

By Thursday nobody wanted chilli.

By Saturday the fourth tub was at the back of the fridge, six days old, and you were standing over the bin doing maths about whether it was still fine. A batch cooking plan for the week is meant to stop that happening, and most of the ones you will find online cause it, because they plan seven days of food against a fridge that only keeps it for four.

Why a batch cooking plan for the week runs out on Thursday

Here is the number every batch cooking page skips. The USDA’s Food Safety and Inspection Service says to use most cooked leftovers within three to four days. Checked on fsis.usda.gov on 10 October 2026.

Cook on Sunday and day four is Thursday. Friday and Saturday are outside the window, however good the tub still looks.

A Sunday batch is four days of food. Planning it as seven is how the last tub ends up in the bin.

So the shape of the week is decided by the fridge, not by your ambition. Monday, Tuesday and Wednesday come out of the fridge. Thursday is a short fresh meal, the one night you actually cook. Friday comes out of the freezer, because a portion went in on Sunday, still warm from the pot, while it had a full clock. Saturday nobody cooks.

That is six dinners from one Sunday and one twenty-minute Thursday. The diagram above is the whole plan, and the rest of this guide is how to fill it.

Cook two things, so it does not feel like one

Nobody wanted chilli by Thursday because four nights of the same bowl stops feeling like dinner and starts feeling like a sentence.

Cook two things instead, and make them different kinds of thing:

• One big wet dish, tripled. Chilli, curry, bolognese, a stew. These reheat well and freeze well, which is the whole job.
• One tray of plain roast protein. Chicken thighs, a joint of pork, a big tray of roast vegetables and chickpeas. Plain on purpose, because plain turns into something else on Wednesday: wraps, a salad, fried rice.

Two dishes in the oven and on the hob at the same time is barely longer than one. And it gives the week a rhythm the family will not notice as leftovers: chicken, chilli, chicken wraps, pasta, chilli.

Here is that week in Chirpy. In the Kitchen you put the batch chilli on Sunday’s dinner and the chicken tray on Monday’s, then set Tuesday, Wednesday and Friday to Leftovers and Saturday to Eating out. Your partner gets a ping that you planned dinner, and the week is on their phone without you sending a photo of the fridge door. Tap to build the list from the plan and the ingredients for the two Sunday dishes land on the shared shopping list, sorted by aisle. The Leftovers nights add nothing, which is exactly right, because they are already in the pot.

Chirpy Basic is free for the whole household, up to six people, no card.

Save the recipe at the size you actually cook

One small thing catches people out the first time, in any planner. A recipe written for four is a recipe for four. Put it on the plan three times and you still get one batch of ingredients, because the list adds each ingredient once.

So save the batch as its own recipe. “Chilli, batch, feeds twelve”, with the mince, the tins and the beans at three times the amount. In Chirpy that is a recipe you add once, by hand, with the servings set to twelve and each ingredient filed under its aisle. Every week after, putting it on Sunday puts the right amounts on the list.

What to batch cook, and what to leave for the night

Not everything survives three days and a microwave. Sort your household’s meals before you build the plan.

The right-hand column is where batch weeks go flat. The sauce is three days old and fine. The rice you cooked with it on Sunday is three days old and miserable. Ten minutes for a fresh pan of rice is what makes a Tuesday chilli feel cooked rather than reheated.

If you are short of candidates for the left column, our guide on how to meal plan for the week has the case for writing down the twenty or so meals your house actually eats. Most of the batchable ones will be on it already.

The Sunday session, in order

About two hours, most of it the oven doing the work. The order matters more than the speed.

1. Oven on first. The roast tray goes in while you are still chopping onions, because it is the longest unattended job.
2. Start the big pot. Onions, mince or lentils, tins, spices. Then leave it on a low heat.
3. Get the shallow containers out. The USDA says to divide large amounts into shallow containers so food cools quickly, and to have it in the fridge within two hours of cooking. A full stock pot in the fridge cools far too slowly.
4. Portion by dinner, not by tub. One container per meal for the house, labelled with what it is and which night it is for.
5. Freeze Friday now. Friday’s portion goes in the freezer today, before it has used up any of its clock. Write the date on it.

That last step is the one everyone skips, and the one the whole plan depends on. The portion you freeze on Sunday has its full quality clock. The one you freeze on day five is the one you were going to throw away anyway.

Put it on the shared list called Freezer while you are standing there. In Chirpy that list is on everyone’s phone, so whoever takes it out Thursday night to thaw is the person who ticks it off. Our guide to a freezer inventory list goes into why that list stays true only if it updates on the way out.

Put the plan where the person reheating it can see it

A batch week has a failure that a normal week does not. The food exists. It is in the fridge, labelled, ready. And on Tuesday somebody else gets home first, opens the fridge, sees a lot of tubs, and makes toast.

The plan only works if it is in the hands of whoever is doing dinner that night, which on most weeks is not the person who cooked on Sunday. A meal plan on one phone is one person’s intentions.

If you want someone to pick the recipes for you and hand you a timed Sunday prep schedule, a paid batch-cooking menu service does that job and we do not. What Chirpy does is put your own twenty meals, the ones your children will actually eat, on a plan the whole household opens, with Wednesday saying “Leftovers” so nobody has to ask what is in the blue tub. That matters more on a Tuesday than a cleverer recipe does.

The plan sits next to the week, too. If Thursday turns out to be swim club and a late meeting, it is the calendar that tells you, and the twenty-minute pasta moves to Saturday without anybody rewriting a whiteboard.

Shop once, for Sunday only

Batch cooking cuts the shopping list more than people expect, because four of the week’s nights need nothing new. The shop is the two Sunday dishes, Thursday’s pasta, and the fresh things for the night: rice, salad, a lemon.

Build it from the plan rather than from memory, and do it on the shared shopping list app the house already uses, so the person who passes the shop on Friday can do it. In Chirpy that is the button on the meal plan, and it skips anything already on the list, so running it twice does not double the tins.

What it does to the grocery bill

Fewer shops means fewer impulse lines, and a triple batch of mince and tins costs less per dinner than three separate recipes with their own jars and their own herbs. We would not put a percentage on it, because nobody honestly can. If you want to see where your total sits, our guide to the grocery budget for family of 4 has the USDA’s own monthly figures to measure against.
