With just 15 minutes of hands-on prep time, you’ll have a berrilicious breakfast ready to grab-and-go all week long.
Ingredients for Blueberry Overnight Oats
This blueberry oatmeal recipe calls for 8 budget-friendly ingredients that might already be in your pantry. No grocery run needed! These are the key items you’ll need:
- Frozen Blueberries: if you want your blueberry oats to actually be blue, then frozen blueberries are the way to go – and they’re more affordable! Fresh blueberries will work as a substitute, but the blueberry “milk” won’t be as vibrant.
- Rolled Oats: old-fashioned rolled oats yield a chewy texture, while quick oats will be very soft. Sometimes, I like using a 50-50 blend of both for just the right balance of both!
- Milk: the thicker and creamier the plant milk, the more puddling-like your oats will be. Cashew milk and full-fat oat milk are both great options.
- Maple Syrup: a small drizzle of Grade A pure maple syrup adds just the right amount of sweetness.
- Lemon Juice: because blueberries and lemons are perfect together! It adds a pop of acidity to the oats, just as it does in these Lemon Blueberry Muffins.
- Chia Seeds: these teeny tiny seeds thicken the oatmeal and give it a boost of fiber, protein, and omega-3 fatty acids.
How to Make Blueberry Overnight Oats
- Blend the blueberries, milk, maple syrup, vanilla, lemon juice, and salt together until smooth.
- Add the oats and chia seeds to a large bowl and mix to combine. Pour in the blueberry milk and stir to combine. Set aside to thicken.
- After 5 minutes, stir the oat mixture again.
- Transfer the oatmeal to jars and refrigerate overnight. Serve the next day with toppings and enjoy!
Caitlin’s Cooking Tips
- Stir the oatmeal twice: once to mix the oat-chia blend and blueberry milk together, and again after the oatmeal has sat for 5 minutes. This prevents the chia seeds from clumping and fully incorporates the blueberry milk with the oats.
- I recommend soaking the oats for at least 4 hours. They’ll technically be ready sooner, but won’t have that delicious, pudding-like consistency. I leave mine overnight to give the oats and seeds plenty of time to hydrate.
- Is the oatmeal too thick after soaking? Stirring in a splash of milk will do the trick! Or, if you’d prefer a thicker consistency, add another tablespoon of chia seeds.
Serving Suggestions
Like my other overnight oats recipes, I almost always eat these blueberry oats for a nutritious breakfast that doesn’t necessarily feel or taste healthy. Rarely do I skip the toppings—some extra blueberries, a sprinkle of hemp hearts, and a drizzle of almond butter make each jar feel so much more substantial.
A jar of blueberry oats comes in handy for snacking, too. Those sleepy afternoons get a little more exciting after a few bites of oats topped with my Easy Vegan Granola or a big dollop of vegan whipped cream.

How to Store Overnight Oats
These blueberry overnight oats will keep in the fridge for up to 5 days. I always store mine in individual sealed mason jars for an easy grab-and-go breakfast.
I haven’t tried freezing overnight oats, but it should work. Just make sure to leave a little room at the top of the jar for expansion. Thaw them in the fridge overnight, then stir them well before serving.
Substitutions and Variations
- Gluten-Free Option: Make sure you use certified gluten-free oats to keep this recipe gluten-free.
- Chia Seed Substitute: This chia can be substituted for an equal amount of ground flaxseeds, but the texture will be slightly less gel-like.
- Blueberry Substitute: You can make this oatmeal with almost any berry you like, such as frozen blackberries, strawberries, or raspberries. You could even use a frozen berry medley!
- Add Protein Powder: For protein oatmeal, blend 1 scoop of your favorite plain vegan protein powder with the blueberry milk. I recommend adding an extra 2 tablespoons of milk and reducing the maple syrup if the protein powder is already sweetened.
- Extra Creamy Option: For the creamiest overnight oats ever, stir 1/4 cup of your favorite dairy-free yogurt in with the blueberry oat mixture (step 2) or right before serving.
Recipe FAQs
Overnight oats are a classic cold, grab-and-go meal, or you can warm them up in the microwave for a hot breakfast.
Make the blueberry “milk” with an extra 2 cups of water, then pour it into a small saucepan with the oats and chia seeds. Simmer the oatmeal over medium heat until the oats are soft and the chia seeds are plump. Remove from the heat and stir in a dollop of vegan yogurt before serving.
It’s always best to add your toppings right before serving the oats.

Blueberry Overnight Oatmeal with Chia Seeds
Ingredients
- 3/4 cup frozen blueberries (no need to thaw)
- 2 cups 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 kosher salt
- 2 cups 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.
Instructions
- 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.
- Mix: Add the oats, chia seeds, and cinnamon and cardamom (if using) to a large bowl and mix well. Pour the blueberry 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.
- 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; leftovers will keep in the fridge for up to 5 days.

Recipe Notes
- 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 blueberry “milk”. Cook the milk, oats, blueberries, and chia seeds on the stovetop over medium heat for 5-10 minutes, stirring occasionally. Serve warm.
This recipe is similar to how I do it however I never thought of blending the blueberries with the milk first! FYI, there’s a typo in the instructions and it says add the strawberry milk (another good idea).
This was so good that I couldn’t stop eating it. The color was also pretty.
Happy you enjoyed, Oli!
Easy, great taste.
Hi! I was looking at the stovetop instructions and they seem to be for a different recipe? Yogurt and peaches?
Also if I want to add in a scoop of protein, w would you recommend modifying? Thx!
Thanks for catching that!
Stovetop Instructions:
Blend blueberries, milk, maple syrup, vanilla, lemon juice, and salt.
Heat blueberry milk in a saucepan until simmering.
Stir in oats and chia seeds, cook for 5-7 mins until thickened.
Let cool slightly before serving. Store leftovers in the fridge.
To add protein:
Stir desired amount of protein powder into the blended blueberry milk mixture before heating on the stovetop. Adjust sweetness if necessary.
Easy and very very very delicious!!!! My husband said he’s been sleeping on overnight oats. He’s now a fan.
Yay! Thank you for introducing, Tracy. Glad to know you both enjoy it.
Can I use something other than the “milks” mentioned, like almond milk?
Yes, you can definitely use almond milk or any other non-dairy milk as a substitute in the recipe. Do note that since almond milk tends to be thinner than coconut milk, you might end up with a slightly less creamy texture compared to using coconut milk.
Here’s how to make the substitution:
Replace the 2 cups of creamy non-dairy milk with the same amount of almond milk or your preferred non-dairy milk alternative.
Follow the rest of the recipe as directed, incorporating the almond milk into the blueberry mixture and mixing it with the oats and chia seeds.
Using almond milk or another non-dairy milk will provide a delicious and nutritious base for your blueberry overnight oats. Enjoy experimenting with different milk alternatives to find your favorite flavor combination!
Very tasty! My fourteen-year-old said he never thought I’d find a way to make him like eating oatmeal, but this recipe did the trick. He absolutely loved it and asked me to make more!
We love that, Brittany! Thank you so much ♥
I followed the instructions and used exact measurements and mine did not end up looking like your photo. They are very thick and the texture is unappealing. Not sure what went wrong. I adore overnight oats but this recipe is unfortunately not for me. I do love the color though!
Ive been making this a lot lately. I triple the recipe to make a big batch and fill jars. I store some in the freezer too. Nice balance of sweetness, cinnamon, and vanilla and its pretty as well. I grind the chia, though, (to make more bio-available) which thickens it up nicely. You can use any fruit you have lying around, its very versatile.
Appreciate the review. Thank you so much, Sonja!
What an “out of the box” idea for oats! Love the fresh thinking. These are delicious, and super easy. Love blueberries, and love the convenience of making overnight oats – in a batch that will last a few days. Well done!
Thank you so much, Stephen!
This recipe turned me into an overnight oats girly. I never liked them before but decided to give these a try and now I’m obsessed!! I can’t wait to try the other overnight oats on the blog.
We love that!
This recipe, like all of your others, is absolutely delicious! I watch your videos and use many of your recipes. On a whim, I decided to toss in some puffed quinoa with the fresh blueberries right before eating. It added a lovely sweet crunch. Thank you for a another great recipe!
We’re happy you found it delicious, Kathy!

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.
