This Blueberry Overnight Oatmeal is a vibrant, refreshing, and fruit-filled breakfast that looks just as good as it tastes! A perfect vegan and gluten-free recipe to start the day. 

Overnight oatmeal is one of life’s most rewarding kitchen hacks — there’s no cooking, no need for multiple bowls…just a cozy jar of creamy, soaked oats ready for you to enjoy the next morning!

This Blueberry Overnight Oatmeal recipe is no exception. Hearty oats, filling chia seeds, sweet vanilla, and a creamy blueberry-infused “milk” make this a refreshing, fruit-packed start to the day that takes almost no time to prepare. Overnight oats like these are far from basic…we’re talking top-notch oatmeal here. Promise.

This recipe is made using accessible and budget-friendly ingredients that will last a long time in your kitchen. Bonus hack: frozen berries are a lot cheaper than fresh! Even better, using frozen berries is actually a win-win here, as they turn the blueberry milk a vibrant purple color. Fresh blueberries will give a more blue-grey color (but will still be delicious if you have them on hand!) A bit of acidity from fresh lemon juice balances everything out and helps the blueberry flavor *pop*, and a drizzle of maple syrup adds the perfect finishing touch of rich, sweet flavor.

The best part about making your own overnight oatmeal is that if you do it right, it doesn’t ever have to get boring. You can customize yours a different way each time you make it! Have fun with it and top your oatmeal with all different types of things, but we’ll talk more about that later! Let’s talk about how to make this extra yummy fuss-free meal…

This Blueberry Overnight Oatmeal comes together in two main steps: making the blueberry milk, then mixing the “milk” with the oats and a handful of chia seeds. Here’s the step-by-step process…

  1. Toss the blueberries, milk, maple, vanilla, lemon, and salt into a blender and blend until creamy.
  2. Pour the blueberry milk over the oats and chia seeds and stir until combined.
  3. Store in the fridge overnight then top as desired and enjoy!

This Blueberry Overnight Oatmeal is delicious on its own, but like I said before, sometimes I like to spice things up and add some variation to mine. Mixing in a little cinnamon or cardamom (or both!) adds a warm depth of flavor and spice that is oh-so-yummy! If I’m feeling like a little extra crunch, I’ll top mine with a handful of pumpkin seeds or hemp hearts. But my #1 favorite? A BIG slather of nut butter on top. Mmm, SO good! And while we’re at it, it never hurts to add a handful of extra blueberries ???? 

Store any leftovers in the fridge for up to 4 days and enjoy hot or cold. If you’re interested in making a stovetop variation of this, check the recipe notes below.

  • Total Time: 15 minutes
  • Yield: Serves 2 to 3 1x
  • Category: Breakfast
  • Method: No Bake
  • Cuisine: American
  • Diet: Vegan


  • 3/4 cup (85 g) frozen blueberries (no need to thaw)
  • 2 cups (475 ml) creamy non-dairy milk* (store-bought or homemade)
  • 1 tablespoon grade A maple syrup, plus more to taste
  • 1 teaspoon vanilla extract
  • Juice of 1/2 small lemon
  • 1/4 teaspoon salt
  • 2 cups (200 g) rolled oats, gluten-free if necessary
  • 2 tablespoons chia seeds or ground flaxseed
  • Optional add-ins: 1/4 teaspoon cinnamon and/or cardamom
  • Topping suggestions: extra fresh or frozen blueberries, pumpkin seeds, hemp hearts, nut butter, etc.


  1. Make the Blueberry “Milk”: Add the blueberries to a high-speed blender along with the milk, maple syrup, vanilla, lemon juice, and salt. Blend on high for 45 to 60 seconds, until the blueberries are finely blended into the milk.
  2. Mix: Add the oats and chia seeds to a large bowl and mix well. Pour the bluebery milk into the bowl, then stir until everything is combined. Let sit for at least 5 minutes, to allow the oats and chia seeds to absorb some of the liquid. Then, mix again to incorporate the extra liquid sitting on top.
  3. Store & Serve: transfer the oatmeal to jars or other containers, then store in the fridge for at least 4 hours, preferably overnight. Top as desired and enjoy cold or warm; leftover will keep in the fridge for up to 5 days.


  • Non-dairy Milk: I recommend using a thick and creamy milk, like cashew milk or oat milk – it adds to the creaminess!
  • Blueberries: Fresh blueberries do not create a vibrant purple color when blended, so I recommend using frozen blueberries for the “milk.” However, feel free to fold in or top the oatmeal with extra fresh blueberries if you’d like!
  • Stovetop Instructions: If you’d like to make this on the stovetop, add an additional 2 cups of water to the peach “milk”. Cook the milk, oats, diced peach, and chia seeds on the stovetop over medium heat for 5-10 minutes, stirring occasionally. Stir in the yogurt, then serve warm.

  2. One of our favorite recipes to prep for breakfasts during the week! Gorgeous color and super tasty topped with fresh berries, bananas and pumpkin seeds! Thanks so much for this recipe!

  3. Caitlin makes the most delicious food. My husband and I watch her videos and I bought the cookbook. We are big fans. I LOVE blueberries (always have some in my house) and this is yummy. I make this one and the peach overnight oats and take them camping. It’s nice to have a special breakfast treat in the morning. In the winter, I’ll try the hot version.

  4. Love that you made a meal-prep/multiple serving version! I always do my jars individually for the week and this will help so much!
