Let’s Make Blueberry Overnight Oats!


I’ve been going little crazy with overnight oats over here! My latest chocolate overnight oats recipe has been a hit and again it’s clear people love this easy and delicious breakfast idea. Today I’m adding this simple recipe for blueberry overnight oats to the list!

This fruity version of overnight oats is filled with blueberry goodness and is packed with complex carbohydrates, protein, and a ton of fibre. It makes for a super healthy breakfast that only takes minutes to put together the night before.

A Refresher: What Are Overnight Oats?


I’ve answered this question a lot on my previous posts, but it’s always good to have a refresher, or provide this information again if you are new here.

“Overnight Oats” takes the cooking out and instead you prepare them the night before by adding dry oats to liquid. The oats soak overnight (or for at least 4-5 hours) in the liquid and by morning you have a soft, cooked oat consistency that is ready to eat…without the cooking!

You can enjoy overnight oats cold right from the fridge or warm them up quickly in the morning, it’s totally up to you and your preference.

If you make overnight oats in a jar or Tupperware container, this simple breakfast can be taken to-go which is great for those who are rushed in the mornings or those who aren’t into cooking a big breakfast. I know from my nutritional consulting experience that a lot of people fall into this category!

Can you put fresh fruits in overnight oats?


Yes! You sure can. 

When it comes to adding fruit to your favorite overnight oats recipes, the sky’s the limit. Fresh berries, or fruits like apple or peach cut into chunks adds great texture to the oats, and the fruits typically soften and meld with the oats adding in even more delicious flavour throughout. 

I like to go with berries most often like blueberries, raspberries, or diced strawberries, but you can definitely try adding apple, peach, pear, or sliced banana to your overnight oats. Note: banana will typically brown after a period of time, so when adding banana I usually recommend stirring it in right before eating. 

The one type of fruit I haven’t tried, and probably wouldn’t recommend in overnight oats would be melons (watermelon, cantaloupe, honeydew, etc.) as I don’t think they would pair well with the oats.

Optional Blueberry Sauce & Yogurt Topping


While I love the simple blueberry overnight oats on their own, this recipe is even more delicious with the addition of my simple blueberry sauce and a dollop of yogurt. The blueberry sauce adds even more blueberry flavour, and the yogurt brings in a perfect touch of creaminess to the oats. 

Here’s what you’ll need for the Blueberry Sauce

  • Frozen blueberries
  • Pure maple syrup
  • Water
  • Cornstarch 

For the yogurt, you can use either plain or vanilla flavoured yogurt of your choice. Choose coconut or almond yogurt for dairy free, or Greek yogurt if you can tolerate dairy.

Easy Blueberry Overnight Oats

Yield: Serves 1
Prep Time: 5 minutes
Soak Time: 5 hours
Total Time: 5 hours 5 minutes

Delicious and healthy blueberry overnight oats that are gluten free, dairy free, vegan, and great for busy mornings!


  • 1/2 cup gluten free rolled oats
  • 1 tablespoon chia seeds
  • 2 tablespoons vegan/plant-based vanilla protein powder*
  • 1 tablespoon pure maple syrup
  • 3/4 cup unsweetened vanilla almond milk
  • 1/4 cup fresh blueberries

Optional Toppings:

  • 2 tablespoons Easy Blueberry Sauce
  • 2 tablespoons plain or vanilla yogurt (dairy free or regular, I love coconut yogurt!)
  • 1 tablespoon crushed walnuts
  • 1 tablespoon toasted coconut flakes
  • fresh blueberries


    1. In a bowl combine the oats, chia seeds, maple syrup, protein powder, almond milk, and blueberries
    2. Mix very well to combine.
    3. Place in the fridge and leave overnight, or 5 hours at a minimum.
    4. In the morning, before eating, warm in the microwave for 30 seconds (see notes) then top all or any of the optional toppings.


*If you choose not to use protein powder: Omit the protein powder and add 2 heaping tablespoons of extra oats.

**Alternatively, you can enjoy the overnight oats cold right from the fridge. I personally prefer it heated because I like warm oats, but it's totally up to you!

***If you want added protein but not flavoured, try unflavoured collagen peptides, linked below. Collagen is not vegan but is tasteless and adds healthy protein to the recipe. Use the same amount as regular protein powder.

A delicious, lightly sweetened, thick blueberry sauce that works as a great topping for overnight oats, or whatever your heart desires!


  • 1/2 cup frozen blueberries
  • 1 tablespoon pure maple syrup
  • 2 tablespoons water
  • 1/2 teaspoon cornstarch


  1. In a small bowl combine the water and cornstarch and whisk to make a "slurry".
  2. Heat a small pot or saucepan over medium heat and add in the frozen blueberries and maple syrup, then mash the berries gently using a fork or potato masher.
  3. Stir in the cornstarch slurry and continue mashing the blueberries as the sauce begins to thicken and bubble, about 2 minutes
  4. Continue to mash and stir until the blueberry sauce is heated through and has a thicker jam-like consistency, another 2 minutes or so.
  5. Transfer to a jar or small container and keep in the fridge to use as a topping for overnight oats, ice cream, toast, etc.


Store in the fridge for up to 5 days.
