Blueberry Overnight Oats make a healthy breakfast packed with whole grains. These oats are perfect to enjoy at home in the morning to take on the go in a jar!


Units Scale
  • 1 cup oats (quick oats or rolled oats, gluten-free if needed)
  • 1 tbsp chia seeds
  • 2 tsp lemon zest
  • 1/4 tsp salt
  • 1/3 cup yogurt of choice
  • 1 tsp vanilla extract
  • 1 tbsp maple syrup
  • 1 cup oat milk
  • 1/2 cup blueberries (fresh or frozen)


  1. Add all the ingredients to a mixing bowl or to a large jar and mix together to combine.
  2. Cover the bowl and place in the fridge to set overnight. If adding to jars, spoon the mixture from the bowl directly into jars or and seal with a lid and place in the fridge.
  3. Remove the overnight oats in the morning and enjoy as is or with your favourite toppings!


If using frozen blueberries you can add them directly in without defrosting. They will defrost in the oats after sitting overnight.

Use quick oats for a softer texture and rolled oats for a chewier texture. This will depend on your personal preference. You can also use a mix of half and half of each!

Do not substitute with steel-cut oats. Steel-cut oats will not absorb the same as other oats do and can’t be substituted in this recipe. I have a recipe for Steel Cut Overnight Oats you can check out if you’d like to use these oats instead.

Taste and adjust as needed. If you prefer your overnight oats to be sweeter, add some more honey. If you prefer your oats to be thinner, add some more oat milk. This recipe can be customized as needed!

Here are some great jars you can use to store your overnight oats. A large mason jar, and these weck canning jars are great options.
