To freeze raw oats, simply place them in an airtight container or freezer bag and store them in the freezer. When ready to use, thaw the oats in the refrigerator overnight or reheat them in the microwave or on the stovetop.

How to tell if oats are bad?

There are several signs that indicate oats have gone bad. If you notice any visible mold growth, off-odors, or a rancid smell, the oats should be discarded. Additionally, if the oats have a significant change in texture, such as becoming slimy or wet, they may no longer be safe to consume. Consuming spoiled oats can lead to foodborne illness, so it’s important to always check for signs of spoilage before eating.

How long are oats good for?

The shelf life of oats depends on the type and how they are stored. Unopened packages of rolled oats can last for 12 to 18 months when stored in a cool, dry place. Once opened, rolled oats should be used within 6 to 9 months. Steel-cut oats have a slightly longer shelf life and can last for up to 2 years when stored properly. Instant oats, on the other hand, have a shorter shelf life and should be used within 6 months to 1 year of purchase.

How to keep oats fresh?

To keep oats fresh for as long as possible, it’s important to store them properly. Store oats in an airtight container in a cool, dry place, away from direct sunlight and heat sources. Avoid storing oats in the refrigerator, as the moisture can lead to spoilage. If you live in a particularly humid environment, consider storing oats in the freezer to prevent moisture buildup. Additionally, always use clean, dry utensils when scooping oats from the container to avoid introducing moisture and contaminants.
