  • pinch of salt
  • ½ teaspoon maple syrup
  • ¼ cup blueberries, plus more for topping

  • Place in the fridge overnight. If you're in a rush you can shorten the soak time to 2-4 hours.
  • The next morning (or when ready to eat), remove lid and give oats a big stir. If they seem too thick you can add a little more milk to loosen the mixture. Top with your favorite toppings and enjoy. You can eat the oats straight from the jar or pour into a bowl for serving.
  • Overnight oats should last up to 5 days in the fridge in a sealed airtight container.



  • Protein powder: I used Nuzest vanilla protein powder. Feel free to skip this if you don't have protein powder on hand.
