How to keep a freezer inventory and organize your freezer

Why a freezer needs an inventory

A freezer hides its contents better than any other part of the kitchen. Packages frost over, drawers fill from the back, and a bag of chili made in January can sit under newer shopping until nobody remembers it is there. The National Center for Home Food Preservation (NCHFP) at the University of Georgia puts the case for a list simply: by keeping an inventory, you will know the exact amounts and kinds of food in the freezer at all times, and it helps keep food from being forgotten.

Uncertainty about frozen food is common. The USDA Food Safety and Inspection Service (FSIS) says that every year thousands of callers to the USDA Meat and Poultry Hotline are not sure about the safety of items stored in their own home freezers. A dated inventory answers most of those questions before they come up, because you know how long each item has been in there.

There is a money angle too. NCHFP notes that a full freezer is the most energy efficient, and that filling and emptying a freezer two, three or more times a year lowers the cost per pound of stored food compared with filling it once a year. Turnover depends on knowing what you have.

What to record for each item

NCHFP's method is a frozen foods inventory posted near the freezer. Each time something goes in, you list the food and the date of freezing; each time something comes out, you check it off. That is the whole system, and its strength is that the list changes at the same moment the freezer does.

The package itself should carry the same information. NCHFP recommends labeling each package with the name of the product, any added ingredients, the packaging date, the number of servings or the amount, and the form of the food, such as whole or sliced. Use freezer tape, marking pens or crayons, or labels made especially for freezer use. It also suggests packing food in quantities that will be used for a single meal, which makes the count on your list match what you actually pull out.

One more field is worth adding even though it is not on the NCHFP list: where the item is. A note such as top shelf or left drawer turns the list from a record of what you own into directions for finding it, which matters most in deep chest freezers.

Give every shelf and drawer a job

NCHFP advises organizing frozen food into food groups for ease in locating, and arranging packages so those that have been in the freezer longest are the first ones used. It sums this up as first in, first out. In practice that means fixed zones, such as raw meat in one drawer, vegetables in another and cooked meals on a shelf, with new packages going behind or under the older ones in each zone.

Where raw meat lives is worth a second thought. FSIS advises separating meat and poultry from other foods so that, if they begin to thaw during a power outage, their juices will not drip onto everything else. A bottom drawer or a lidded bin works well for this.

New food needs room at first. NCHFP recommends placing fresh packages against the refrigerated surfaces in the coldest part of the freezer and leaving a little space between them so air can circulate, then storing them close together once they are frozen. FSIS gives the same advice from the other direction: never stack packages that are still freezing; spread them out in one layer and stack them only after they are frozen solid.

Keep the temperature steady and check it

An inventory only works if the food is holding up, and that depends on temperature. NCHFP says to maintain the freezer at 0 °F or lower because foods lose quality much faster at higher temperatures, and to keep a freezer thermometer inside and check it frequently. FSIS adds that a thermometer matters most after a power cut or mechanical problem, and that a refrigerator freezer compartment that cannot hold zero or gets opened often is best used for short-term storage.

Large hauls slow freezing down. NCHFP recommends adding only as much unfrozen food as will freeze within 24 hours, which is usually 2 to 3 pounds per cubic foot of freezer space, and suggests setting the control to -10 °F or lower about 24 hours before a big batch goes in.

If you have a manual-defrost freezer, the inventory helps with that chore as well. NCHFP says these freezers need defrosting at least once a year, or when more than a quarter inch of frost covers a large area, and recommends scheduling it for when the inventory is low and the job can be finished within one to two hours.

Common freezer inventory mistakes

Only updating the list when food goes in. A list that never gets crossed off soon shows food you ate weeks ago, and people stop trusting it. Checking items off as they come out is half of the NCHFP method.

Overloading after a big shopping trip. Adding more than the 2 to 3 pounds per cubic foot that NCHFP suggests slows freezing, and food that freezes too slowly can lose quality.

Treating storage times as expiry dates. FSIS says food stored constantly at 0 °F will always be safe and that recommended freezer times are for quality only. An old item belongs at the front of the line, not automatically in the trash.

Paper list, spreadsheet or app

A paper list on the freezer door is the classic choice, and it has real advantages: it is right where you need it and costs nothing. Its weak point is that it cannot sort itself, so finding the oldest item means reading every line. A spreadsheet or phone note fixes the sorting but lives somewhere other than the freezer, which makes it easy to forget to update.

A phone app can sit in between. FreezeKeep, for example, turns a photo of your own freezer into a map you draw shelves and drawers on, records the date and spot for each item as it goes in, and keeps an Eat first list sorted with the longest-frozen items at the top. Whatever tool you pick, the habit is the same one NCHFP describes: write it down on the way in, cross it off on the way out.
