How Long Does Butter Last in the Fridge Once Opened?

The average household often wonders how long opened butter can last in the refrigerator. Generally, butter can last up to two weeks in the fridge after being opened. This is a good starting point, but with proper storage, it can stay fresh for up to one month.

Avoiding Spoilage with Proper Storage

Proper storage is key to extending the shelf life of butter in the fridge. Once opened, store the butter in an airtight container or a plastic wrap that seals tightly around the surface of the butter. Avoid exposure to air and direct sunlight, as these can cause the butter to oxidize and spoil more quickly.

How Long Does Butter Stay Fresh in the Fridge?

Around two weeks is often considered the optimal freshness period for butter when stored properly in the fridge. This period can increase to a month if the storage conditions are right.

Freshness and Quality

During this time, the butter will maintain its creamy texture and mild flavor. However, it is important to regularly check for any signs of spoilage, such as off odors or changes in color. If you notice any of these, it's best to discard the butter to avoid any health risks.

Freezing for Long-term Use

For those who need to store butter for a longer period, freezing is an excellent option. I have had great success with freezing butter for up to a year. Once frozen, butter can be kept in its original packaging or transferred to a freezer-safe container for optimal preservation.

How to Freeze Butter

To freeze butter, simply remove it from the fridge and shape it into cubes, a sphere, or strips. These shapes will help the butter defrost quickly and reduce air exposure. Store the frozen butter in an airtight container or wrap it tightly in plastic wrap and place it in a freezer bag to prevent freezer burn.

Storage Guidelines for Refrigerated and Frozen Butter

According to the USDA, both opened and unopened butter can be stored in the refrigerator for one to three months. For freezing, the recommended storage time is up to one year. These guidelines ensure that the butter remains safe and palatable for extended periods.

Conclusion

In summary, the proper storage of butter can significantly extend its fresh period. Refrigerating it in an airtight container can keep it fresh for up to one month, while freezing it can extend its usability to a year. Regular checks for spoilage are essential for ensuring the quality of your butter.
