How Do You Make Overnight Oats?
For this recipe, it’s as easy as taking some rolled oats, non-dairy milk (you can use dairy milk if that’s your thing), chia seeds, blueberries, and nuts and mixing it all in a leak proof container (I prefer mason jars) and soaking it overnight.
Soaking the oats overnight allows them to absorb the liquid and soften them up so they are ready for eating.
What Makes These Blueberry Overnight Oats Healthy?
- Whole Grains - naturally, overnight oats are made with oats. Oats are a great source of whole grains. My favorite oats (and we go through a lot of them) are GF Harvest Gluten-Free Organic Rolled Oats.
- Chia Seeds - there is a good amount of these super seeds in this recipe. Chia seeds are a great source of omega-3s and are rich in antioxidants. They are also great for providing fiber and protein.
- Sweetened with Frozen Blueberries - this recipe doesn’t call for any added sugar (even the natural kind). The key to adding sweetness to these oats is in the frozen blueberries. As the blueberries thaw overnight they will produce a perfectly sweet blueberry syrup that helps to lightly sweeten the oats.
- Walnuts - lots of healthy fats in these power nuts and they also contain a good amount of protein and are high in vitamins, minerals, and antioxidants. Did I mention these are power nuts!?
Blueberries - you can use fresh blueberries in place of the frozen. Just know that the frozen blueberries create a nice sweet syrup once they thaw, which helps to sweeten the oats. But if you want to use fresh blueberries and would like the oats to be sweeter, just add some pure maple syrup.
Milk - the recipe is written with non-dairy milk (I prefer almond milk). But if you aren't dairy free, you can use regular cow's milk (preferably organic so you know it's hormone and antibiotic-free).
Chia seeds - I love adding in super seeds to just about anything. If you don't have chia seeds on hand, you can use hemp seeds or flaxseeds. But I highly recommend chia - they soak up the liquid well and pair very nicely with the oats!
How Long Do Overnight Oats Last?
You know I love anything that is great for food prepping, and overnight oats are one of those things! Overnight oats will stay good in the fridge for 3-5 days, so go ahead and make a few servings and you’ll have breakfast ready for a few days!

Blueberry Chia Overnight Oats
- 1 cup rolled oats (certified gluten-free if needed)
- 2 cups non-dairy milk (dairy-milk works too)
- 2 tbsp. chia seeds
- 1 cup frozen blueberries
- ¼ cup chopped walnuts (or any other nut)
- Use 2 mason jars, or any other leak proof container, to prep overnight oats. Start by placing ½ cup oats in each jar.
- Pour 1 cup milk and 1 tbsp. chia seeds in each jar. Stir oats, milk, and chia seeds until oats are fully submerged in the milk.
- Add ½ cup frozen blueberries and 2 tbsp. chopped walnuts to each jar. Tightly close up each jar.
- Refrigerate overnight. Oats will be ready in the morning, or will stay good for 3 days.
- You can either eat these straight out of the fridge or warm them up a little bit. It's totally a personal preference (I like mine cold, but my husband warms his up).
- If you'd like a little extra sweetness, feel free to drizzle some maple syrup on them before eating.
- I use pint-sized/16oz mason jars for each individual serving.
- You can combine all ingredients in one large jar or bowl and divide servings out in the morning if you don't need them in individual jars.
- Overnight oats will stay good in the fridge for 3-5 days.
These are so simple and so good. Thanks for sharing the recipe. We make these frequently!
So glad you like these. Love how simple they are as well!
Only question I had was you didn’t list a mason jar size. I used 2 half pints and had leftovers, so assuming you used a pint?
Hi Jeanne - yes, I use pint sized jars when I make these. Thanks for the question... I will update the notes to specify this. Hope you enjoyed the oats!
Can you use different frozen fruit ??
Absolutely! Any frozen fruit will work. I've used mixed berries before, but any variation will work.

Do you have to cook the oats first!
Nope... you just put them in the jar as is and overnight the oats will soak up the milk. And the oats will soften from soaking up the milk.
Yay, so glad you enjoyed this... it's one of my favorite overnight oats recipes! And thanks for taking the time to leave a review!
Thanks for this. I have some of these with yogurt but I think think this will be easier! Love these that you fix in jars.
Yes, the jars are great! Enjoy!
Great recipe. Turned out well.
Thanks so much for sharing and happy you enjoyed this recipe.
I tried the blueberry recipe and followed the instructions to the letter and the results were delicious.
Thank you for sharing all of your recipes.
So glad you enjoyed this recipe, Maria! Thanks for sharing 🙂
can I use fresh blueberries?
Hi Katie - Yes, fresh blueberries will work great! Frozen ones do release some juices which provide some natural sweetness, so they will be less sweet with fresh. If you'd like them a little sweeter, I recommend using some pure maple syrup. Enjoy!
