In this brief guide, we are going to answer the question “how long can overnight oats stay in the fridge” with an in-depth analysis of the shelf life of overnight oats. Moreover, we are going to discuss tips to properly store overnight oats.
So without much ado, let’s dive in and figure out more about it.
How long can overnight oats stay in the fridge?
Generally, overnight oats last for about 3-5 days if stored properly in the fridge all the time at or below 40 degrees Fahrenheit in an air-tight container.
Overnight oats with some fruits added to them last for about 2 days when stored properly in the fridge at or below 40 degrees Fahrenheit. On the other hand, overnight oats made with yogurt last for about 7 days when stored in an air-tight container in the fridge.
Overnight oats made with milk last for about 3-5 days (depending mainly upon when the milk is going to expire).
So, you should always store your overnight oats at 40 degrees Fahrenheit or below provided that you are going to eat them within a few days, or else it is better to freeze them. Bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore it is always advised to store your overnight oats at a lower temperature to preserve their freshness for a long time.
Thus, the cold temperature of the fridge will decrease the rate of bacterial growth and will subsequently prolong the shelf life of your overnight oats.
How long can overnight oats last at room temperature?
Overnight oats last for about 2 hours when left out of the fridge at room temperature.
You should discard the overnight oats that have been left in open for more than 2 hours as bacterial growth takes place at a faster pace between the temperature of 40 and 140 degrees Fahrenheit, therefore there are greater chances of the overnight oats being already contaminated with bacteria when left out for more than 2 hours.
Moreover, if the temperature of the surroundings is about 90 degrees Fahrenheit, then the process of spoilage takes place at a faster pace and it is recommended to discard overnight oats that are left out in the open for more than an hour at 90 degrees Fahrenheit.
How long do overnight oats last in the freezer?
Properly stored overnight oats last for about 6 months in the freezer.
Thus, the shelf life of overnight oats increases owing to the cold temperature of the freezer that halts the microbial growth on it.
How to thaw frozen overnight oats?
When it comes to thawing overnight oats, there are a couple of ways to do so and you can choose any of them depending upon your choice.
