A Summer Meal Prep Staple

I’m always looking for ways to make my mornings more peaceful and making easy breakfasts that are both nourishing and filling is always at the top of the list. Discovering overnight oats felt like uncovering one of life’s greatest morning hacks. There’s no cooking, no need for multiple bowls, and infinite possibilities for flavor. 

They’re truly the best summer meal prep staple and this blueberry overnight oats recipe is no exception. What could you possibly need more than a refreshing, fruit-packed start to the day?

Ingredients for Blueberry Overnight Oats

This recipe is made using accessible and budget-friendly ingredients that will last a long time in your kitchen which means you can enjoy these oats all summer long. Here are the basics:

  • Oats: I always use either old-fashioned rolled oats or quick oats. Steel cut oats are too unprocessed for overnight oats and are better suited for hot oatmeal recipes like this Instant Pot Steel Cut Oatmeal.
  • Blueberries: Frozen, sweet blueberries are key here for achieving the vibrant purple-blue color. And as an added bonus, they’re so much cheaper than fresh! 
  • Lemon: Adds a bit of acidity that balances everything out and helps make the blueberry flavor pop.
  • Milk: ​Any non-dairy milk will work, but the creamier the better. Try coconut milk (from a carton), cashew milk, or homemade almond milk. 
  • Pure maple syrup: A bit of sweetness to finish it and enhance the sweetness in the blueberry milk. If you’re out of maple syrup, try agave nectar. 
  • Chia seeds: This omega powerhouse is not only a great source of fiber, but helps thicken the cold oats into a creamy consistency. 

How to Make Blueberry Overnight Oats

side-by-side images of the preparation process of overnight oats
  1. Make the blueberry milk by blending the blueberries, plant milk, maple syrup, vanilla, lemon juice, and salt until the berries are finely blended.
  2. Mix the oats and chia seeds together in a large bowl. Pour in the strawberry milk and stir until well combined. Let sit for 5 minutes, then stir once more to incorporate the extra liquid sitting on top.
  3. Transfer the blueberry oats to jars or another sealable container and refrigerate for at least 4 hours, or preferably overnight.
  4. Serve as desired and enjoy!

Caitlin’s Cooking Tips

  • Don’t be afraid to customize your overnight oatmeal. The best part about making your own overnight oatmeal is that you can customize the flavor each time you make it. Adjust the sweetener to taste, add protein, or swap in some creamy yogurt in place of part of the dairy-free milk. Plus, you can top these oats with just about anything. I recommend a little almond butter or peanut butter plus more juicy blueberries. 
  • Try a different kind of berry. If you’re out of frozen blueberries, try my Strawberry Overnight Oats or in the summer months you might like this Peaches & Cream Overnight Oatmeal recipe.

Serving Suggestions

Enjoying these blueberry overnight oats for breakfast is the obvious choice, but they also make a delicious afternoon snack, quick on-the-go lunch, or even dessert with a dollop of coconut whipped cream. I like to top mine with a big slather of nut butter on top with a handful of pumpkin seeds, hemp hearts, and fresh blueberries for extra blueberry flavor.

How to Store Blueberry Overnight Oats

These blueberry overnight oats will keep in the fridge for up to 5 days. I’ve never frozen overnight oats – theoretically it should work, but overnight oats are so easy to make fresh, I’d only test freezing them if they are going to go bad before you can enjoy them.

If you’d like to heat these overnight oats, microwave them in 30 second bursts until warmed through or try my stovetop instructions (listed in the recipe card!).

Substitutions and Variations

  • Nut-free option: Many plant milks are nut-based, but not all. If you are allergic to nuts or making these oats for school lunches, use soy milk, rice milk, or oat milk. These plant milks are the creamiest, nut-free varieties. 
  • Gluten-free option: If you use certified gluten-free oats, this recipe is naturally gluten-free. 
  • Thicker oatmeal option: If you like creamy oats, use 1 3/4 cups plant-based milk and 1/4 cup dairy-free yogurt. 
  • Add protein powder: If you love a high-protein delicious breakfast , add up to 1 scoop of your favorite neutral tasting protein powder to the mix. Adding protein powder will make your oats mixture thicker, so I’d recommend adding an additional 2 tablespoons of plant milk to balance out the added dry ingredients. Additionally, if the protein powder contains sweetener, omit or reduce the maple syrup to taste. 
  • Add spices: Sometimes I like to spice things up and mix in a little cinnamon or cardamom. 
  • Chia seeds substitution: Replace chia seeds with an equal amount of ground flaxseeds.

Recipe FAQs

Should I add toppings to my overnight oats before or after soaking?

In most cases it will be better to add your toppings afterwards, but if you are making these oats for busy mornings and won’t have time to add them the next day you can add them on top after mixing and transferring to individual jars.

How long do overnight oats need to soak?

For best results, you will want your blueberry oats to soak for at least 4 hours. They will be edible sooner, but they won’t have that delicious pudding-like texture and the oats will be chewy. 

Can I add nuts or seeds to my overnight oats?

Of course! If you’d like to add nuts to the mix, I’d recommend chopped pecans, slivered almonds, or pumpkin seeds (pepitas). You may also want to try these PB&J Overnight Oats.

Can I use frozen fruit in overnight oats?

Yes – in fact, in this recipe, I recommend it because it makes these overnight oats a vibrant purple color (fresh blueberries will turn it a blue-grey color). There’s no need to thaw them either, making this recipe one of my favorite, fast meal prep recipes.

Start your day with these blueberry overnight oats! They're vibrant, refreshing, and infused with sweet blueberries. Gluten-free, Vegan.


  • 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.


  • 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 and chia seeds 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.

  1. 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!

    1. 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.

      2. Yay! Thank you for introducing, Tracy. Glad to know you both enjoy it.

      1. 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!

  3. 5 stars
    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.

    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!

    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!

    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.

      1. Thanks for your question! You can find the nutritional information for the recipe at the bottom under ‘Nutrition’. It provides a breakdown of the calories and other nutritional details per serving.

    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!
