How to track expiring food in your pantry
The NestBoard team · 2026-08-28
The real problem isn't tracking, it's seeing
Most families throw out expired food not because they forgot to write down the date, but because the can of coconut milk got pushed to the back in November and nobody saw it again until spring cleaning. The best tracking system in the world doesn't help if you can't see what you have.
That's why rotation matters more than any app. When you unpack groceries, move older items to the front and put new purchases behind them. It sounds obvious, but it only works if everyone in the house does it every single time. The minute someone shoves a new jar wherever it fits, the system breaks.
Painter's tape and a Sharpie
If you open a package of something that doesn't have a clear use-by date once opened, write the date on painter's tape and stick it on the container. Chicken broth, almond milk, that tub of sour cream. Painter's tape peels off cleanly and doesn't leave residue like permanent marker on the lid does.
Some families write the purchase date. Others write the expiration date. It doesn't matter which as long as you pick one and stick with it.
Spreadsheet trackers (for people who like spreadsheets)
A shared Google Sheet with three columns works: item name, expiry date, location. Sort by date and you see what needs eating first. The trouble is that someone has to update it every time groceries arrive, every time you use something up, and every time you move a jar from the pantry to the fridge.
In practice, the sheet gets updated twice and then abandoned. It works beautifully for the kind of household where one person already enjoys inventory management. For everyone else, it adds a step that competes with putting the groceries away before the ice cream melts.
Apps with expiry alerts
A pantry app can watch the dates so you don't have to. NestBoard's pantry does exactly this. You scan a barcode or type in what you bought, give it an expiry date, and anything falling due within three days gets flagged as expiring soon. Open the Pantry when something is close and an "Expiring soon" list comes up, nearest dates first, and you can use the item or send it to the shopping list straight from there. It surfaces once a day, so it prompts rather than nags. The same count rides along on the dashboard as a pantry alerts card, so you see it without going to look for it.
The advantage over a spreadsheet is that the app does the sorting and nudging for you. You still have to add things when they arrive, but you don't have to remember to check the list. The app checks for you.
It also lives in the same place as your meal plan, so when you sit down to plan the week you can check what needs eating first instead of planning from scratch and finding the bell peppers on Sunday.
What actually works
Rotation first. Always. No system survives a pantry where new stuff gets piled on top of old stuff.
After that, pick the lowest-effort tracking method you'll actually maintain. For some families that's painter's tape on everything. For others it's an app they're already opening every day to check the calendar or add to the grocery list.
The goal isn't perfect visibility into every item. It's catching the big offenders before they go bad. The half-gallon of milk, the berries, the leftovers in the back of the fridge. Those are where the waste happens, and those are the easiest things to track.
