  • Glass jar (Mason jar, Weck jar, empty nut butter jar)


With chia seeds

  • ½ cup old-fashioned rolled oats gluten-free certified if necessary
  • 1 teaspoon chia seeds optional but recommended
  • ½ cup milk plant-based alternative to make it vegan
  • 1-2 teaspoons maple syrup optional
  • 2-3 tablespoons yogurt plant-based alternative to make it vegan


  • Add the oats, the chia seeds (if using) and maple syrup (if using) to a jar or bowl. Add in the milk. Close the jar with a lid (or cover the bowl). Place in the fridge to set overnight or at least 4 hours.
  • In the morning, or when soaked, add in yogurt and give it a good mix.
  • Add the toppings of your choice such as granola, fresh fruit or jam.


  1. The best oats to use for overnight oats are old-fashioned rolled oats as they will soften without getting too mushy. You could eventually use quick-cooking oats (not instant oats) but they tend to fall apart too quickly.
  2. If you're using gluten-free certified oats, make sure they are as thick as regular rolled oats or adapt the oat to milk ratio. You might need to add a little less milk if they are relatively thin. You can test a few different ratios to find out what you like and what works best with the oats brand you have.
  3. You can make overnight oats with water, a mix of milk and water or even orange juice. If using water, it's recommended to add yogurt to make it creamier and to flavor it with vanilla extract or jam. 
  4. The best jar size for 1 single portion of overnight oats is 16 oz. This leaves enough space to add your toppings to the same jar.
  5. Overnight oats can last in the fridge for up to 5 days, which is great for meal-prepping. Only add yogurt and other toppings right before serving.
  6. You can eat overnight oats cold hot or cold. You can reheat them in the microwave for 1-1:30 minutes or on the stove before adding the yogurt and toppings.
