Recipe Notes

Meal Prep and Storage

    • To prep and store: It is so simple to prepare this dish entirely the evening before. Once it's mixed, it will stay in the fridge in an airtight, resealable container for up to 3 to 4 days. However, after the first 24 hours, the oatmeal will get mushy. You can prep extra by waiting to mix the milk in until the night before you serve it.

    • To freeze: Freezing is not recommended.  The texture of the oats will not be the same and instead will be too watery.
