Overnight oats are one of the best breakfasts to prep ahead of time. You can make overnight oats up to five days in advance.

Store prepared overnight oats in the fridge in an airtight container or jar. Give them a stir before serving.

Can you freeze overnight oats? Yes, you should be able to freeze overnight oats just fine. I recommend storing individual servings in airtight containers.

Keep in the freezer and enjoy within 3 months. Let the oats sit in the fridge overnight to defrost.
