How to save money on groceries, when the leak is not at the shelf

Rose · 16 September 2026

The biggest saving is not cheaper items, it is fewer wasted ones. Food thrown away is money already spent, and most of it was bought for meals that never got cooked. Decide dinners before you shop, choose recipes that share ingredients, buy only what those dinners need, and put the list in the order you walk the shop.

You bought coriander, spinach and half a block of feta for a dish you saw on your phone two weeks ago. All three are still in the fridge. Two of them are no longer food. That is the part of the grocery bill nobody writes a listicle about, because it does not happen in the shop. It happens at 18:10 on a Wednesday, when you open the fridge, see you are missing one thing, and order instead.

This guide is about that gap. It still covers own-brands, reduced items and the rest, honestly scored, because some of them do work. But it starts with the larger number.

Where does the money actually leak: price per item or food you never cook?

Here is the size of the leak, measured.

Dutch households throw away 25.5 kg of solid food per person per year, worth about EUR 100 per person. That is the 2026 Voedingscentrum figure, and it is an improvement: the 2022 measurement put it at 33.4 kg and EUR 138 per person. So the trend is good and the absolute number is still large. For a two-person household, EUR 100 each is EUR 200 a year in food that was carried home, refrigerated, and binned.

Now the other lever. A-brands in the Netherlands are on average 40 percent more expensive than store brands, per Rabobank analysis, and the Consumentenbond once measured a full house-brand basket as 45 percent cheaper than the A-brand equivalent. Those are big percentages. They are also percentages you can only bank once, on the share of your basket that is still branded, and most Dutch shoppers have already made that switch on the obvious items.

Put them side by side and the shape of the problem changes. Downshifting is a one-time discount on things you buy. Waste is a recurring full-price loss on things you bought and did not use. Every ranking page on this keyword leads with the first and buries the second. None of them puts a kilogram or a euro on the waste, which means none of them tells you which lever is bigger.

There is also an honest limit here. I cannot tell you what share of a typical grocery bill is specifically ingredients bought for a recipe that never got cooked. I looked. The figures floating around for that are unsourced, so I am not going to invent one. What I can say is what gets binned, and it is not tins.

What does one forgotten bunch of herbs really cost over a year?

A Hungarian measurement study weighed the actual bins of 165 households over a week and split avoidable waste by category: fresh vegetables 10.00 percent, fresh fruits 7.54 percent, bakery products 17.62 percent, dairy products 7.95 percent. That is Hungary, not the Netherlands, and I have not found a Dutch split at the same level of detail, so treat it as directional rather than local.

Directionally, it is damning enough. Fresh produce, bread and dairy are precisely the aisles a recipe sends you to. Nobody bins rice. People bin the half bunch of coriander, the spinach that went slimy at the bottom of the drawer, the feta, the cream you bought for one sauce.

Run your own arithmetic on one item. A bunch of fresh herbs is a euro-ish purchase. Buy it for a specific dish, cook the dish, use a third of it, let the rest die: you have paid full price and captured maybe a third of the value. Do that twice a month across herbs, a bag of salad, the odd dairy item, and you are in the neighbourhood of the EUR 100 per person the Voedingscentrum measures. You do not need a spreadsheet. You need to look in the drawer.

The second version of the same leak is buying the thing you already have. You get home, and there is an open jar of gochujang behind the mustard. You now own two. Neither of them will be finished.

Why does the advice to plan your meals almost never stick?

Every guide says plan your meals. It is tip one on most of them. Nobody asks why so many people do it on Sunday and abandon it by Wednesday.

The failure is in where the plan comes from. A Sunday plan is usually built out of obligation: dishes you feel you should cook, balanced, sensible, drawn from a recipe site you opened specifically to make a plan. You have no particular appetite for any of them. You chose them in a planning mood, and you will cook them in a tired mood, and those are different people.

Meanwhile there is a folder on your phone full of dishes you genuinely wanted to make. You saved them because you watched someone cook them and thought yes, that. That is real appetite, already expressed, already filtered by your own taste. And it never makes it onto the plan, because the saved folder is a graveyard and opening it feels like admitting how many are in there.

The second failure is the missing ingredient. A plan collapses on the first dinner where you have four of five things. Missing one item is not a small problem at 18:10, it is the whole decision. That is not a discipline problem. That is a list problem, and it is fixable upstream.

The third failure is that plans are written for a whole week when nobody knows what Thursday will feel like. Four dinners across seven nights, with two of them shared with something else you bought, survives contact with real life better than seven immovable slots.

How much cheaper is cooking the thing you planned than ordering instead?

This is the number that outweighs every coupon.

A warm self-cooked meal in the Netherlands costs about EUR 2.18 per adult on Nibud’s costing, and Nibud’s own two-person calculation lands at EUR 4.58 for a couple. Two independent-ish routes into roughly the same territory, which is reassuring.

Meal delivery in the Netherlands has been reported at EUR 20 per order and, on a different basis, at EUR 11.40 per person per order. Both figures are old, from 2017, and prices have not moved downwards since. Take the more conservative per-person number and you are still comparing EUR 11.40 against a cooked meal at about EUR 2.18 per adult. The gap is not close. Take the per-order number for a couple and it is still comfortably worse per head than cooking.

Now combine it with the fridge. The expensive failure is not ordering food. It is ordering food on top of ingredients you already own, which then go off, so you pay twice: once for the takeaway, once for the spinach that becomes waste. One collapsed dinner plan costs more than a month of diligent coupon clipping. That is the arithmetic the price-hack pages never run, because their whole frame is the shop, and this happens after the shop.

How do you build a plan out of recipes you already chose?

The method is short. It has to be, or it becomes the second job you were trying to avoid.

1. Open the folder where you save cooking videos. TikTok saves, Instagram reels, whichever one you actually use.
2. Pick four dinners you want to eat this week. Not seven. Four leaves room for leftovers, one improvised night, and one night that goes wrong.
3. Look at what those four share. Herbs, an aromatic, a protein, a dairy item. If nothing overlaps, swap one dish for a neighbour that does.
4. Check what is already open in the fridge and the cupboard before you write anything down. This is the tip every guide gives and nobody does, because it requires standing in the kitchen with a list, which is exactly when you should be doing it.
5. Write one list, in the order you walk the shop.
6. Buy that list.

Step two is the one doing the work. You are not adopting a new discipline, you are cashing in a choice you already made. The appetite is not hypothetical, it is two weeks old and still there.

Step three is where the money is. Which brings us to overlap.

Which recipes should you pick together so nothing is bought twice?

Overlap is the cheapest saving available, and it is invisible if you plan dishes one at a time.

Here is a worked example. You have five saved videos. Three of them can be made to carry each other.

• Gochujang chicken thighs. Two chicken thighs, one tbsp gochujang, one tbsp soy, a teaspoon of honey, spring onion to finish, rice.
• Spring onion and egg fried rice. Cold rice from last night, two eggs, the rest of the spring onion, a splash of the same soy.
• Cucumber salad with the same chilli paste. Cucumber, a teaspoon of gochujang, rice vinegar, sesame.

Buy a pack of chicken thighs, one bunch of spring onion, one tub of gochujang, one bottle of soy. Cook rice once on Monday for two nights. Three dinners come out of a shop that looks like one dinner’s worth of new ingredients. The gochujang tub stays in the fridge and gets used twice in the same week rather than once in six months, which is the difference between a condiment and a waste item.

Contrast the alternative: gochujang chicken on Monday, a Tuscan white bean thing on Tuesday, a Thai curry on Wednesday. Three cuisines, three sets of aromatics, three half-used bunches of herbs, three jars that each get one spoonful. Same number of dinners, nearly double the shop, and a bin that fills up ten days later.

The rule of thumb: pick dishes that share a flavour base, a fresh herb, or a protein. Then let one cooked thing feed two nights. Rice, roast chicken, a batch of beans.

This is also the part that no price-comparison page can help you with, because overlap is not a property of the shop. It is a property of your plan.

Does a shopping list in aisle order change what you spend?

Partly. Let me be precise about how much, because this one gets oversold.

Academic work on supermarket behaviour puts unplanned purchases at about 20 percent of purchases, with roughly 18 percent of purchased categories unplanned, and more than 60 percent of shopping trips containing no unplanned buying at all. You will also see a much older industry claim that 60 percent of supermarket purchases are impulse buys. That 60 percent number is from a 1995 study and it defines impulse far more loosely. The careful research is the 20 percent.

So: impulse buying is real, it is not the dominant leak, and most trips are clean. What an aisle-sorted list does is reduce the time you spend wandering, which reduces the surface area for the 20 percent. Walk the shop once, top to bottom, and you are not doubling back past the biscuits for the third time.

The bigger benefit of aisle order is not psychological, it is completeness. A list sorted by aisle gets finished. A list scribbled in the order you thought of things gets abandoned near the end, and the item you skip is the one that kills the dinner on Wednesday. Structure is the thing that stops a plan from failing on a missing ingredient.

Do not expect aisle order alone to change your bill much. Expect it to change how many of your planned dinners actually happen, which is where the money is.

Do the classic tips still work, and which ones are worth the effort?

They are not a straw man. Here is honest scoring.

Own-brands: worth it, once. The gap is genuine, 40 percent on average between A-brands and store brands. Do the switch across staples in one trip and never think about it again. The reason it is not the headline is that it is a one-time move on a shrinking share of your basket, whereas waste recurs weekly. It also does nothing for produce, which is what you actually bin.

Reduced and yellow-sticker items: worth it only if it fits the plan. A discounted pack of chicken thighs you were going to buy anyway is free money. A discounted tray of aubergines you have no dish for is a future waste item at a discount. Reduced-price waste is still waste.

Loyalty pricing and coupons: low value, high friction. The effort-to-euro ratio is poor, and the cognitive load competes with the thing that actually matters, which is deciding what you are cooking.

Bulk buying: good on dry goods, bad on fresh. Rice, tinned tomatoes, pasta, oil: buy big. Fresh produce in bulk is a bin-filling exercise, and that measurement study puts fresh vegetables at 10.00 percent and fresh fruits at 7.54 percent of avoidable household waste.

Frozen and canned: genuinely underrated. Frozen spinach does not rot. Frozen peas do not rot. If you know you only need a handful, frozen removes the waste risk entirely.

Stock-take before shopping: correct, and everyone skips it. The fix is not willpower, it is doing it while your list is open in your hand, in the kitchen, before you leave.

Budgeting apps: not a grocery tool. Worth saying because several cost-of-living pages still cite Money Dashboard, a UK budgeting app whose consumer web and mobile apps closed on 31 October 2023. It aggregated bank spending, it did nothing with recipes. Knowing you spent too much on food last month does not tell you what to cook tonight.

Recipe apps with planners: useful, with a boundary. Good Food: Recipe Finder, from Immediate Media Company London Limited, runs on iOS and Android with recipe discovery, meal planning and shopping lists, priced at GBP 0.99 for six months for new subscribers, auto-renewing at GBP 24.99 per year. It plans from its own recipe library. I could not find a reliable source saying it imports recipes from TikTok, Instagram or YouTube videos, so I am not going to claim it does or does not. If your appetite lives in a saved folder rather than a recipe library, that distinction is the whole thing.

What does the buy-for-two-days approach get right and wrong?

The most upvoted advice on this topic, on forums and in comment sections, is: stop doing a big shop, buy for two days at a time, waste nothing.

The waste logic is correct and I will not argue with it. Buy two days of fresh food and almost none of it dies. If you live above a supermarket and enjoy the walk, this genuinely works.

What it gets wrong is the cost it moves rather than removes.

Three or four trips a week is three or four exposures to the shop instead of one. With around 20 percent of purchases unplanned, quadrupling your trips is not a neutral act. It is also three or four decision points about dinner, taken while hungry, on the way home, which is exactly the state in which people give up and order.

And it costs time. Twenty minutes each way, four times a week, is more than an hour of your life weekly, which is the second job the question was trying to avoid.

The synthesis: one planned shop for the dishes you have chosen, plus dry goods and frozen, and accept one short top-up mid-week for anything genuinely perishable. You keep the waste benefit on the fragile items and you keep the single decision about what you are eating.

Can an app read the recipe out of a video you saved?

Yes, and this is the part that closes the loop between the saved folder and the list.

Yumzi is a Dutch meal-planning app that reads the recipe out of TikTok and Instagram videos you saved, plans a balanced week of dinners, and builds one aisle-sorted grocery list you confirm at your own supermarket.

Reads the video means what it says. Not just the caption, which is often three emoji and a link. The app takes the spoken amounts and the on-screen text and pulls out the actual quantities: two chicken thighs, one tbsp gochujang, a bunch of spring onion. From four or five of those, it builds a weekly dinner plan and merges the ingredients into one list in the order you walk the shop, so the spring onion appears once rather than three times.

On the AI question, which you are right to ask: these are real recipes from real creators you chose. Yumzi never invents a dish. When the video does not contain enough to read a recipe from, we say so rather than filling the gaps with plausible-sounding amounts. A guessed quantity is worse than no quantity, because you only find out it was wrong with the pan already hot. That limit is the point of the product, not an apology for it.

For readers in the Netherlands there is a convenience on the end of it, once the plan exists. One tap sends your shopping list to your Albert Heijn basket. You review, confirm and pay at AH yourself. The plan can also be scored against the Schijf van Vijf, so a week built from things you fancied does not quietly become five nights of fried rice.

Food is 12.6 percent of total Dutch household expenditure. Cutting the waste inside that share, and cutting the takeaway that follows an abandoned plan, moves more money than shaving the unit price of the things you were going to buy anyway.

What does a cheaper week of dinners look like in practice?

Concretely, end to end.

Saturday, five minutes. Open your saved folder. Scroll past the ones you saved because they looked impressive. Pick four you would actually eat on a Wednesday. Say: the gochujang chicken, the spring onion fried rice, a lemon pasta, a chickpea stew.

Still Saturday, two minutes. Let the app read the four. It pulls the amounts out of each video. Spring onion appears in two, so it appears once on the list. The soy appears in two, so it appears once. You already have rice and soy, so you cross them off while standing at the cupboard.

One shop. The list is in aisle order, so you walk the shop once, top to bottom, and you are out. No backtracking to the herbs, no third pass down the snack aisle.

Monday. Cook the chicken. Cook extra rice on purpose.

Tuesday. Fried rice from Monday’s rice, the rest of the spring onion, two eggs. Ten minutes. This is the dinner that would otherwise have been a delivery order at EUR 11.40 per person or more, against a cooked meal at about EUR 2.18 per adult.

Thursday and Friday. The pasta and the stew. If Thursday goes sideways and you order, the stew survives to Friday, because it was chosen to be robust.

Sunday. Nothing has died in the drawer. That is EUR 100 per person a year you stop paying in instalments.

You do not need a new discipline. You need to cook the things you already chose, and to leave the house with a list that will not strand you at 18:10 missing one ingredient.

Open your saved folder, pick four dinners you already wanted to cook, and let Yumzi read them into one list before you leave the house.
