Prep Time 10 minutes

Total Time 2 hours 10 minutes
Servings 1


  • 3/4 cup fresh blueberries, divided
  • 1/2 cup rolled oats
  • 1 Tbsp chia seeds
  • 1/2 cup plain greek yogurt
  • 1/4 cup unsweetened nut milk (I used almond milk)
  • 1/2 tsp vanilla extract
  • 1/2 a lemon, zest only
  • Optional toppings: nut butter, maple syrup


  • Start by mashing 1/2 a cup of the blueberries into a bowl or airtight container. This helps to release their juices. Reserve the remaining 1/4 cup blueberries for topping.
  • Next, add rolled oats, chia seeds, plain greek yogurt, almond milk, and vanilla extract to the mashed blueberries.
  • Stir everything together well, cover, and refrigerate for a minimum of 2 hours. Or, leave them in the fridge overnight so that breakfast is ready in the morning.
  • Remove the overnight oats from the fridge, give them a stir, and top with the rest of the blueberries and lemon zest. You can add nut butter or maple syrup, if desired!


*These overnight oats will keep in an airtight container in the fridge for 4-6 days. There is no need to heat them.
*If you'd like to prep a large batch for meal prep, feel free to increase the recipe as desired!
*For a vegan version, swap greek yogurt with thick, creamy vegan yogurt. Do note that this will significantly lower the protein content of this recipe.
*You can use any milk or plant-based milk alternative for this recipe. Just try to choose one that is unsweetened and unflavoured!
*For a gluten-free version, ensure you're using certified gluten-free rolled oats.
