Blueberry Lemon Overnight Oats With Chia
These blueberry lemon overnight oats are made with just 7 ingredients, like chia seeds, greek yogurt, fresh blueberries, and lemon zest. It’s such an easy, no-cook, make-ahead breakfast recipe that happens to taste DELICIOUS!

Overnight oats have consistently been one of my favourite breakfasts to prepare over the years. When I was training to become a dietitian, I honestly think I made them for breakfast almost everyday!
They are SO quick and easy to make – no cooking involved and you just need a few minutes to mix everything together. Pop the oat mixture in the fridge before bed, and you’ve got nutritious, balanced breakfast ready to go in the morning!
What I also love about overnight oats are all the different flavour combinations you can come up with. I have to say – this Blueberry Lemon Overnight Oatmeal might just be one of my favourites!!

What’s The Difference Between Overnight Oats & Regular Oatmeal?
The primary difference between overnight oats and regular oatmeal is in the way it’s prepared.
Overnight oats are made in advance and they require ZERO cooking. You simply mix dry oats with a liquid (like milk, nut milk, or yogurt) and let it sit for a few hours or overnight. The oats soften by soaking in the liquid, rather than through cooking.
Regular oatmeal is typically cooked on the stovetop or in the microwave. It’s often enjoyed hot!
Do You Eat Overnight Oats Cold?
Yes! I typically eat my overnight oats cold, making them perfect for the warmer months and for quick grab-and-go breakfasts.
That said, I’ve also made overnight oats that I heat up in the microwave right before I want to eat them. It’s totally up to you!
Are Overnight Oats Healthy?
You bet! Overnight oats are an incredibly healthy breakfast option that is totally customizable.
Rolled oats are an excellent source of soluble fibre, which helps to slow digestion, lower cholesterol, improve blood sugar control, regulate bowel movements, and promote the growth of good gut bacteria.
Oats are also an excellent source of micronutrients, like manganese, phosphorus, magnesium, copper, iron, zinc, and B-vitamins. On the macronutrient side, oats are a source of complex carbohydrates and plant-based protein!
In addition to the health benefits of oatmeal, this recipe is packed with other nutrient-dense ingredients like:
- Chia seeds, which are packed with fibre, omega-3 fatty acids, protein, and minerals like magnesium, calcium + iron.
- Plain greek yogurt, which is a great source of protein, gut-friendly probiotic bacteria, and micronutrients like calcium, potassium, vitamin A + B12.
- Blueberries, which are an excellent source of fibre, antioxidants, and micronutrients like vitamin C, K, B6 + manganese.
- Lemon zest, which is a good source of fibre, antioxidants + vitamin C!
How To Make Blueberry Lemon Overnight Oats
To make these blueberry lemon overnight oats, start by mashing fresh blueberries into a bowl or airtight container. This helps to release their juices.
Next, add rolled oats, chia seeds, plain greek yogurt, almond milk, and vanilla extract to the mashed blueberries.
Stir everything together well, cover, and refrigerate for a minimum of 2 hours. Or, leave them in the fridge overnight so that breakfast is ready in the morning.
Remove the overnight oats from the fridge and top with fresh blueberries and lemon zest. That’s it!
How Long Do Overnight Oats Keep?
Overnight oats will keep for 4-6 days in an airtight container in the fridge. This makes them a perfect breakfast meal prep option – just make a large batch, and you have a healthy breakfast ready for the week!
Recipe Variations & Modifications
- This blueberry lemon overnight oats recipe tastes great with a scoop of almond or peanut butter. This is a great addition if you want to add a bit more healthy fat and protein to this meal!
- While I personally find this recipe sweet enough, you can always add a touch of maple syrup or honey for extra sweetness.
- For a vegan option, simply swap the greek yogurt with a plain vegan yogurt. Choose one that’s thick and creamy, and low on added sugars. Do note that this will lower the protein content of this recipe.
- I used unsweetened almond milk for this recipe, but feel free to use any milk or plant-based milk alternative that you enjoy!
- While oats are naturally gluten-free, if you’re on a strict gluten-free diet you will need to ensure that you use certified gluten-free oats for this recipe.

Hi Kim! I’m so so happy to hear you enjoy this one! Thank you so much for sharing. I hope you have a great week 🙂
Finally got around to making this. It is so delicious, easy and fast to make. I have made it twice this week. I also get a feeling of fullness without that drag down to my energy levels. Thank you so much, I love this recipe and will be making it again. I did decide to put a little more almond milk the second time, just for a more runny texture. Thank you Carrie; my next plan is to make the grilled nectarines with burrata salad, looks so yummy.
Hi Adriana! Thank you so much for the kind comment. I’m so happy to hear you enjoyed this one and that you found it a satisfying way to start your day :). Yes if you prefer more runny oats definitely add a splash more of the milk till it gets to your desired texture! I so hope you enjoy the grilled nectarine salad too – would love to know how it goes for you!
PS – if you liked these overnight oats, I have some more fall/winter versions for when the seasons change. I love this apple one and this blood orange one, too!!
Hi Carrie,
I am beginning my dietetic internship tomorrow and wanted to have quick and easy meals ready to grab and go in the mornings. I have meal prepped this recipe for the first few days of the week. Instead of using 1/4 cup of almond milk and 1/2 Greek yogurt, I used 3/4 cup of plain kefir. Thank you for your nutritious recipes!

Hi Sophie! Thanks so much for sharing your experience. I’m so happy to hear that you made this one for the start of your DI!! I hope it gave you all the energy you needed :). I remember making TONS of overnight oats during my DI days too (those early food service mornings are no joke haha). Wishing you best of luck with everything!!!
Carrie,
My bad, my internship started today, not yesterday. I had the oats this morning and they were so tart! They definitely woke me up! Next time I will follow your instructions to just use the zest of a lemon. I added 1/2 tablespoon of lemon juice to my oats in addition to the kefir in place of the milk and yogurt. The kefir + lemon juice combo was a bit overpowering. 😛
Hi Sophie! Oh no – hopefully it was still edible and woke you up for internship day haha!! But yes, try this just with the zest! I find the lemon flavour much more subtle and not overpowering that way. I’d love to know if you give it another try 🙂
Best of luck with the DI!!
This recipe was so easy to make. I made two days worth, and I really enjoyed the flavor combo a lit. That lemon zest really made it pop. Thank you for this delicious recipe
Hi Tyler! Thank you so much for sharing!! I’m so happy to hear you enjoyed this recipe idea!
PS – If you liked this flavour combo, you may enjoy this lemon blueberry smoothie and these lemon blueberry oatmeal cookies, too! Similar flavour combos, but in different forms 😉
Delicious! The lemon zest is such a nice touch. And I enjoy how this can easily be made in the evening, ready to eat in the morning. Thank you for another easy, delicious and healthy recipe.
Thank you so much for taking the time to leave a review, C! It’s so appreciated. I’m so happy to hear you enjoyed this one. I’m all for ready-to-eat breakfasts ;)!!
