Recipe Notes

  • To prep and store: The recipe is perfect to prepare entirely the day before. After mixing, it will keep in the refrigerator in an airtight, resealable container or covered tightly with plastic wrap for up to 3 to 4 days. However, the oatmeal will get mushy after the first 24 hours. To ensure the best texture every morning of the week, do not add the milk to the jar until the night before serving.
  • To freeze: Freezing is not recommended. The texture of the oats will not be the same and instead will be too watery.
