Freezer inventory: how to know what's in your freezer without digging
How to know what's in your freezer without emptying it every time: what to write down, five methods compared and where each one fails, a printable freezer inventory list, and how to set it up in an afternoon.
What gets thrown out without being used
A freezer doesn't spoil food; it pauses it. The UK Food Standards Agency (FSA) puts it that way, and the US FDA adds that food kept at 0 °F (-18 °C) is safe indefinitely and that the times in its chart are for quality only. So the problem isn't that food goes bad. It's that you don't know what's in there, and what you don't know you have, you don't cook.
Spain's Ministry of Agriculture, Fisheries and Food (MAPA) measures what households throw away every year. In 2025 it was 1,101.8 million kilos or liters of food and drink. Per person, per year, 18.23 kg or liters were unused products, meaning thrown out as bought, before any cooking. Another 5.28 were dishes already prepared. That year, 68.8% of households threw out something unused. If your household were four people and threw out the average, that would be about 161 lb (73 kg) a year of untouched food (our calculation: 18.23 × 4).
Two cautions so you don't read more into it than it says. The panel doesn't separate the freezer from the rest of the home and doesn't say why each item was thrown away, so it isn't a figure about forgotten food. It's the size of the problem an inventory tries to shrink: food bought to be used and not used. A freezer where everything is a white block is where that problem is easiest to see.

What a useful inventory has to say
Paper or app, if your freezer inventory list doesn't carry these five things, it can't answer the question that matters: what am I cooking this week?
- What it is. The dish, not the container: "lentil stew with chorizo", not "container 3".
- How much. Portions or units. Freezing in small portions also helps food cool quickly, according to the FSA, and you thaw only what you'll eat.
- When it went in. The day you froze it.
- Use by. The date you want to have eaten it by while it's still good. It's a quality target, not a safety date.
- Where it is. Drawer, shelf or basket.
The date it went in isn't enough by itself, because not everything lasts the same. With the same freeze date, the FDA chart gives steaks 6 to 12 months for quality, ground meat 3 to 4 months, and soups and stews 2 to 3. If you only write the day, you have to remember every timeline. If you also write "use by", the list decides for you. The time for each food, with sources, is in our guide to how long food lasts in the freezer.

Five ways to keep it, and where each one breaks
None of them is bad. Each one breaks in a different place, and the table shows where.
| Method | Cost | Who sees it | When it goes out of date | Does it warn you before something is past it? | Works for several people or homes? |
|---|---|---|---|---|---|
| Paper list on the door | Paper and a pen | Whoever walks past, in that home | When someone takes something out or puts something in without crossing it off or writing it down, and nobody notices | No | Several people, yes, if all of them write things down. Several homes: one sheet in each, and neither sees the other |
| Whiteboard with a dry-erase marker | A whiteboard and a marker | Whoever walks past, in that home | When it gets wiped with a sleeve. It holds little: good for what's in there today, not for dates three months away | No | Same as the paper list |
| Shared spreadsheet | Free if you already use an account with spreadsheets | Anyone with the link, from anywhere | When opening your phone in front of the freezer is more work than pulling out the package and looking | Only if you set up a color rule or an alert yourself | Yes: it does this best |
| Label on every container (marker, paper or NFC) | From tape and a marker to NFC labels | Whoever opens the freezer and reads the lid. No overview without taking things out | Almost never: the information travels with the container. But there's no list, and to know what you have you have to look | No, except NFC with an app that does it | Anyone who opens the freezer. Each container carries its own |
| App | Depends on the app | You, on your phone, without opening the freezer | Same as the others: when it isn't written down going in. An app can't see inside | Yes, if the app works out the date and sends reminders. Not all do | Several homes, if the app keeps them apart. Between people, it depends on the app |

How to choose, without overthinking it:
- You live alone or with a partner and have a small freezer: the list on the door, and that's it.
- You batch-cook and freeze a lot: labels on the containers plus a list or an app for the overview. The label tells you what each block is; the list tells you how many there are.
- Two homes, or several people who shop: a shared spreadsheet or an app.
Set it up in one afternoon
This is the only time you empty it. After that, the inventory saves you from doing it again. Allow a couple of hours.
- Empty the freezer by drawer. Work one drawer at a time and keep the rest shut. Put what you take out in a cooler bag or a fridge drawer, and write it down as it comes out. The less time it's out, the better.
- Throw out what you can't identify. At 0 °F (-18 °C) food doesn't spoil, so this isn't a safety question: it's quality, and knowing what it is. An unlabeled block with thick frost that you remember nothing about isn't worth keeping. For the rest, check the quality timelines in the guide to how long food lasts in the freezer.
- Write each item down with the five details. What it is, how much, when it went in, use by, and where. Cooked food has its own fridge and freezer rules, which are in the guide to how long leftovers last in the fridge. If you keep meat in its original package for more than two months, the FDA recommends overwrapping it with heavy-duty foil, plastic wrap or freezer paper, or putting the package inside a plastic bag.
- Group by zone. One zone per kind of food: meat, fish, vegetables, cooked meals, bread. A basket or a box per zone works as a drawer. Write the zone on the list, because that's what answers "where is it?"
- Put the oldest in front. It's first in, first out (FIFO): what's been in longest goes up front and within reach; new items go behind. What you've cooked yourself goes right at the front, because it has no factory date.
- Keep the list where you'll use it. On the door if it's paper; on your phone if it's a spreadsheet or an app. A list you have to go looking for doesn't get updated.

The one rule that keeps it alive
Write it down going in, cross it off coming out. Nothing goes in without a line and nothing comes out without a stroke. Everything else is secondary: a perfect freezer inventory you stop updating after two weeks is worse than a simple one you keep up.
- A five-minute check each week. It can be the day you shop. See what has a "use by" this week or next and decide what you're cooking. Check that what you see in the drawer matches what the list says.
- When you take something out to thaw, cross it off and write "thawing" beside it. Per the FSA, use it within 24 hours of it being fully defrosted. Thaw in the fridge, not on the counter.
- If someone at home doesn't write things down, don't chase them: make writing easier than not writing. The pen tied to the list, the sheet on the door and not in a drawer, one line per item. Accept that it won't be perfect and fix it at the weekly check.

Printable template
It's a table you print from this page, with nothing to download and no email to leave. One landscape sheet covers the freezer of one home.
Freezer at: Last checked:
| What it is | Portions | In (date) | Use by | Drawer or shelf | Out (date) |
|---|---|---|---|---|---|
| Lentil stew with chorizo | 4 | Sep 12, 2026 | Dec 12, 2026 | Drawer 2 | |
The example uses 3 months for “use by”, the top of the FDA range for soups and stews (2-3 months). It’s a quality time, not a safety time. Times for each food are in the guide to how long food lasts in the freezer. Freezer at 0 °F (-18 °C). Thawed: use within 24 hours (FSA).
Printing shows only the template, on one landscape US Letter sheet. Need more lines? Print another.

With two homes
One inventory per home. That's the rule. The house in the village or at the beach has a freezer you hardly see, so the list is all you know about it from a distance. Put the home's name on the template's header line ("Freezer at: the beach house") and check the list before you leave and when you arrive.
In FreshTrack, each home has its own products, containers and shopping list, and you switch homes by tapping one. Each keeps its own inventory, with nothing mixed with the other's.
By hand, or with FreshTrack
All of the above can be done by hand, with a sheet of paper.
We built FreshTrack because we didn't want to work out each container's date by hand. Here's what it does in the published version:
- Three locations: pantry, fridge and freezer. In the product list, one tap on "Freezer" shows only what's in there. The list of containers has no such filter, but each container's row says whether it's in the fridge or the freezer, and there's a search box.
- Each container carries a calculated date. When you fill one, you pick the food type (there are 12, like cooked rice, legumes / stew or raw meat) and whether it goes in the fridge or the freezer; the date comes from that. You can change the days for each type in Settings.
- Quantity. For a product, you note how many units you have, and the number drops as you use one.
- A daily reminder before it expires. By default, two days ahead and at 9:00. Both can be changed in Settings.
- Siri. Say "What do I have in the freezer in FreshTrack" and it tells you how many things there are and names the first few, with a short list on screen. It covers products and containers together.
What it doesn't do: it can't see inside your freezer. As with any method, someone has to log what goes in. It has no field for drawer or shelf either; if you want that, it goes in the name or the note of the container.
The dates FreshTrack calculates are approximate estimates based on general food storage guidelines (such as the USDA FoodKeeper guide and food safety recommendations). They don't replace the use-by or best-before date printed on the package, nor your own judgement about the food's look, smell or taste. When in doubt, throw it out.
It's free, and it's ours.
