Overnight Oats 101: Everything You Need to Know
Below are answers to common questions and helpful tips for prepping overnight oats.
What Kind of Oats Should I Use?
Old-fashioned rolled oats are recommended for overnight oats because they hold their texture after soaking. Quick oats can become mushy, while steel-cut oats remain too firm unless pre-cooked.
Variations
This peanut butter banana version is just one option. Try other combinations like:
- Hemp seeds and fresh berries
- Cacao nibs and cherries
- Peaches with vanilla extract and cinnamon
- Pears with maple syrup and chopped walnuts
- Flavored vegan protein powder for extra protein
Are Overnight Oats Eaten Cold?
Yes—overnight oats are delicious chilled straight from the fridge. If you prefer warm oats, heat them briefly on the stove or in the microwave.
What If I Don’t Have a Mason Jar?
Any airtight container or Tupperware works well. Mason jars are handy for grab-and-go breakfasts, but they aren’t required.
How Long Do Overnight Oats Last in the Fridge?
Overnight oats keep for up to 5 days in the refrigerator, depending on the fruit and toppings you add. This makes them excellent for weekly meal prep.
