These Gluten-Free Blueberry Overnight Oats are made with only six simple, nutritious ingredients. Quick and easy to make, they’re the perfect make-ahead breakfast or snack on busy days! Dairy-free, too.
The Best Overnight Oats
We’re a big fan of superfood recipes here at Cotter Crunch, especially when it comes to breakfast foods! For instance, we love our superfood Instant Pot oatmeal and superfood spirulina smoothies.
However, when life gets busy, these healthy overnight oats are our go-to recipe. Not only are they packed full of vitamins, nutrients, fiber, healthy fats, and complex carbs, but they’re also great to prepare in advance.
That means we can meal prep single-serving portions to grab and go throughout the week. Perfectly sweetened, these oats are a hit with even the pickiest of eaters and keep you full through lunch!
Ingredients You’ll Need
Below is an overview of the ingredients and instructions to make this recipe. Be sure to scroll down to the recipe card below for the complete details!
- Blueberries – Feel free to use fresh or frozen blueberries.
- Gluten-Free Old-Fashioned Rolled Oats – Make sure to look for certified gluten-free oats! Also, do not substitute other types of oats such as quick oats or steel-cut oats. Otherwise, the texture of your overnight oats won’t be the same.
- Chia Seeds and Flax Seeds – A great source of fiber and healthy omega fats, these also help thicken the oats.
- Ground Cinnamon – Just a pinch adds extra depth to the oats. Cinnamon can also help reduce inflammation!
- Dairy-Free Milk – We use almond milk or coconut milk, but any dairy-free milk you like best will work.
- Sweetener – Feel free to add maple syrup or honey for added sweetness!
Nutrition Tip – Adding small amounts of acid liquid such as vinegar or lemon juice is said to help activate phytase, an enzyme that breaks down phytic acid, making the oats easier to digest.
Blueberries: The Superfood Powerhouse
These little blue gems are called superfoods for a good reason. Blueberries are packed with nutrition! For example, blueberries are:
- Rich in antioxidants
- A good source of vitamin C and vitamin K
- An excellent source of manganese
- An excellent source of fiber
How to Make Blueberry Overnight Oats
- Combine the ingredients. In a medium-sized mixing bowl, add all the ingredients, and stir or combine.
- Chill. Store the oats in a jar with a lid, or divide it between two single-serving weck or mason jars. Chill for at least 5-6 hours.
- Serve. Top your oats with your toppings of choice, and enjoy!
Tip – If you can soak the oats for 12 to 24 hours, it will help break down the resistant starch, making them easier to digest and allowing your body to absorb more nutrients. But if you’re short on time, soaking them for at least 6 hours will still do the trick.

Tip: If adding sweet potato or pumpkin puree, mix ¼ to ½ cup in with the other ingredients. Then, add a dash of cinnamon or nutmeg, and extra milk as needed!

Notes

Serving Tip – To enjoy warm, simply transfer the oats to a microwave-safe bowl or leave them in the jar if it’s microwave-safe.

do you have to prep the chai seeds before putting them in
Can you clarify what you mean by prep?
Can you use Klondike protein oats? Thanks
Hi Karen! Do you mean Kodiak Protein oats? The one with whey protein? Either way, just make sure it’s gluten free if you are sensitive to gluten. Also, the texture might vary, probably thicker but so add more milk/liquid if needed. Still delicious though!
Hi there,
Are the macros per jar? Or per two jars?
Sorry about the confusion, Sarah! We are going to make that more clear. The nutrition is per jar assuming you are dividing the ingredients between 2 jars. 🙂
I’d like to add egg white protein powder. Should I increase the amount of almond milk?
Is your protein powder dissolvable? Or thick? Most egg white protein is pretty thin so I don’t think you’d need to add more milk. But keep me posted!
Thank you! I actually tried this to see without increasing and it was perfect! I truly enjoyed this recipe and will be adding into my breakfast rotation! Thank you!
Great! So glad it worked out Geo!
I will be making this for sure! Looks delicious! My question is “where” did you get your divided dishes with the lids? Sorry..I know this is an older post of yours, so hope you see my question! Thankyou!
Hi Colleen! I bought those containers a while ago on Amazon but I think they are still available! https://amzn.to/3Kl4GOO
I’ve made this recipe both ways (with oats and with sweet potato and even butternut squash) I replace the flax with hemp seeds as flax doesn’t agree with me. Delicious, great texture and easy!
Oh awesome! Thanks so much for feedback Karen! I love the butternut squash option!
The picture shows other variations (One Appears to be strawberry and nuts) do you have the ingredients would love to try them they look delicious.
I don’t see strawberry. Do you mean the grapefruit or the one mixed with sweet potato? Sorry for confusion.
Could you use steel cut oats instead of rolled?
I’m not sure. I haven’t tried soaking steel cut. It might be best to slightly cook them first then prep for overnight. Does that make sense?
Yes you can, they just don’t swell up like rolled oats do. I read that they should be soaked first, but I haven’t always done that for better digestion. Combine in a bowl 1 Cup oats, 2 Cups warm water, 2 Tblsp of apple cider vinegar or lemon juice. Cover & leave on the counter (not fridge) for at least 7 hrs, no more than 24 hrs though. I do overnight. Next day strain & quick rinse with fresh water, then you can either cook them or prepare for overnight oats. Hope this helps
Oh wow! That is super helpful. Thank you for being such a fabulous recipe tester!
Quick question: are these meant to be eaten cold then? Or do you heat it up when you take it out of the fridge? I am going to try this but cold oatmeal doesn’t sound too appealing.
Either way. I actually enjoy them cold. It taste kinda like a parfait!
Hi, could you tell me whether this will keep in the fridge for a number of days or does it need to be prepped every night?
Sure! It keeps all week in the fridge, easy!
The cakes are so fresh, the recipe you made is so great and you have really clever hands, I really like the way you decorate them.
I tried this last night and it didn’t turn out nearly as creamy as the image. Any ideas about what I did wrong?
Hmm, what kind of oats did you use? I added coconut milk on top before stirring and eating the next day. Maybe that was it? Happy to update that in notes too.
Thank you so much for making this website! This (and so many of the other recipes) look delicious! You have inspired me to start a new me at age 51!
So glad it can help Cathi! Let me know if you need any other information or guidance.
Love how simple this is and a week’s worth of on the go breakfast can be made in a very short amount of time!
Thanks! Simple, quick, and tasty…triple threat! 😉
