Oatmeal is one of the market’s most nutritious and versatile whole grains.
Loaded with fiber, essential vitamins and minerals, oatmeal is a mainstay in household pantries worldwide.
Whether you fancy using it as a hot breakfast cereal, base for savory and comforting porridge, or want to add texture and fiber to baked goods, thereâs no denying that keeping oatmeal on hand is a good idea.
However, if you havenât used your oatmeal for anything more than a cupboard accessory, you may wonder when itâs time to throw it out.
This article reviews the shelf life of oatmeal and how to know when your stash is ready for a refresh.
Shelf life of oatmeal
Oatmeal has a reasonably long lifespan compared with many other foods.
Yet, its precise shelf life can vary dramatically depending on how it was processed, whether it has been cooked, whether any perishable ingredients have been added, and the storing method.
Similarly to dried rice or pasta, commercially processed and uncooked rolled, quick, or steel-cut oats will typically last at least 12 months â and up to 2 years if the package remains unopened or the oats are stored in an air-tight container.
Commercially processed oats usually undergo a steaming process, contributing to their long shelf life.
Unstabilized oats are oats that have not been steamed during processing and, therefore, have a reduced shelf life of about 3â4 months.
Oatmeal containing other ingredients like dry milk or fruit can last anywhere from 4 months to 1 year, depending on the type of added ingredients and how itâs stored.
If unsure, check the package label for a âbest byâ or âuse byâ date.
Similarly to soups and stews, previously cooked or prepared oatmeal shouldnât be kept longer than 3â4 days before you toss it. However, if you freeze it, it can be kept safely for up to 3 months.
Summary: The shelf life of oatmeal can range from just a few days to up to 2 years, depending on how itâs processed, stored, and prepared.
How to tell whether your oatmeal has gone bad
When stored properly, uncooked oatmeal isnât considered a potentially hazardous food. This means itâs unlikely to spoil in such a way thatâll make you sick if you eat it once itâs past its prime.
That said, the quality of the oats will decline over time, and they may become stale, change color, or develop flavors that arenât particularly palatable.
If dry oats are exposed to moisture while stored, theyâll be more susceptible to mold growth. If you see any type of mold growing on your oats â whether cooked or dry â do not eat them.
If youâre unsure whether your oats are still good, start by inspecting the color, texture, and scent. If you notice any dark spots, strange odors, or clumping, itâs probably best to throw them out or add them to the compost bin.
Summary: Check your oatmeal for mold or changes in scent, color, or texture to evaluate whether itâs safe to consume.
Storage tips to maximize the shelf life of oatmeal
The trick to maximizing the shelf life of your oatmeal is the storage method.
Youâll want to ensure that uncooked oats stay as dry as possible. Minimizing exposure to light and oxygen can help, too.
Store them in a cool, dry place like a pantry or cupboard. After their original packaging has been opened, transfer them to a water- and air-tight container, such as glass, stainless steel, or ceramic jar, to help keep them fresh.
When storing cooked oatmeal, opt for a container with a tight seal, and keep it refrigerated until youâre ready to eat. If youâre freezing it, store it in an air-tight container to prevent freezer burn.
Summary: To maximize oatmealâs shelf life, keep it in a cool, dry place with minimal moisture, air, and light exposure.
Summary
Oatmeal is a nutritious pantry staple in households all over the world.
