If you need a quick, healthy breakfast that tastes like a treat, these blueberry overnight oats are the perfect choice! They’re made with rolled oats, almond milk, chia seeds, maple syrup, vanilla, blueberries, and just a pinch of salt for balance and flavor.
Most mornings in our house are a bit of a scramble, so having a few jars of these oats ready to go in the fridge is a game-changer. I started making them for my son, and now they’ve become a weekday staple for both of us.

Recipe Notes
- Texture: These overnight oats are thick and creamy thanks to the oats and chia seeds soaking up the milk.
- Satisfying: This recipe will keep you nourished and full. You can add protein powder or Greek yogurt to make it even more substantial!
- Easy: All you have to do is mix it in a bowl and stick it in the fridge! It’s a great way to get kids to prep their own breakfast.
- No Refined Sugar: All the sweetness comes from the oats, maple syrup, and the blueberries.
Key Ingredients
You can find the full list of ingredients in the recipe card below. Although they're all simple items you probably already have in your kitchen, here are a few things to note:
Oats: We use old fashioned rolled oats in this recipe. If you're gluten-free, make sure you are using certified gluten-free oats. I love using these gluten-free protein oats for added protein!
Almond milk: I prefer using homemade unsweetened almond or cashew milk in this blueberry overnight oats recipe, but feel free to use what you have on hand! You can also use dairy milk as well.
Maple syrup: Feel free to swap it out for another liquid sweetener of your choice!
Blueberries: You can use fresh or frozen blueberries.
Recipe Tips
Stir well. Make sure to stir everything well before refrigerating so the chia seeds don't clump.
Chill overnight. Let the oats sit for at least 4 hours, but overnight is best for the ideal texture.
Adjust the liquid. Adjust the amount of milk to get the consistency you like—use more for looser oats, less for thicker.
Add mix-ins. You can make this recipe more substantial by adding some protein powder or a few spoonfuls of yogurt.
Add toppings. When you're ready to eat, you can top it with more blueberries, or add granola, nuts, or nut butter.

Storage Instructions
Store your blueberry overnight oats in an airtight container in the refrigerator. Mason jars or small glass containers work especially well and make for easy grab-and-go breakfasts.
They’ll stay fresh for 4 to 5 days, so you can prep a batch on Sunday and have breakfast ready all week. Just give them a stir before eating, and add a splash of milk if they’ve thickened up too much.
FAQs
Old fashioned oats (aka rolled oats) are the best option because they soften just the right amount overnight, whereas instant oats can become mushy. Steel-cut oats aren't ideal, because they don't soften enough without cooking, and stay too hard.
Yes, frozen blueberries work beautifully, as they thaw overnight. The blueberry color will bleed into the oats, but I find that quite pretty!
They’re usually eaten cold, but if you prefer them warm, you can microwave them for 30 to 60 seconds before eating.
All toppings should be added after the oats have soaked, especially if they're something crunchy like chopped nuts or granola. If you add toppings before the oats soak, they'll lose their crunch.
