Why you'll love these
Handful of ingredients - Literally 5 simple ingredients: oats, blueberries, chia, maple syrup and milk.
5 minutes - All you do is stir ingredients together then leave them overnight in the fridge in a covered container. Simple.
Healthy - These overnight oats with blueberries are a great source of fiber, as well as various vitamins and minerals.
Great make-ahead breakfast recipe - You can double or triple the quantity to have easy, delicious breakfasts all week long! A great way to meal prep.
Oats - I like using old fashioned oats here because they have a chewier texture, but instant or quick oats work fine. You could even use steel cut oats.
Blueberries - Fresh juicy blueberries are best! Frozen can be used, although your overnight oats will likely end up a bluish colour.
Milk - Gives you nice creamy oats. I like non-dairy milk like almond or oat milk, but any kind of milk works. You could even use coconut milk for extra creaminess.
Chia seeds - These contain healthy fats and help the oats set with a firm, pudding-like texture.
Maple syrup - My favourite sweetener! It really adds to the flavor. You can also use any other liquid sweetener like agave nectar or date syrup.
Berries - You're welcome to switch out the blueberries for any other kind of berry. Raspberries, strawberries or blackberries all work really well.
Low sugar option - You can use a low sugar sweetener (like stevia), use less maple syrup or skip the sweetener altogether to make this blueberry overnight oats recipe low sugar.
Gluten free option - Be sure to use certified gluten free oats.
How to make blueberry overnight oats
In a large bowl or resealable container, thoroughly mix together oats, blueberries, chia, maple syrup and milk until combined.
[OR, alternatively to make your oats a purple/blue colour: first blend ½ cup blueberries and milk in high speed blender until completely smooth. Then mix blended milk into oats, chia, maple and remaining blueberries in large bowl.]
Cover bowl/container and refrigerate for at least 4 hours (ideally overnight), until mixture has noticeably thickened.
Next morning, divide oats between two mason jars, and optionally top each mason jar with any of the following: granola, seeds, cacao nibs, toasted coconut or extra blueberries.

Protein - Adding protein will keep you fuller for longer. To make these into high protein overnight oats, simply add a scoop of your favourite protein powder. Alternatively add hemp hearts, flax seeds or nuts (but you tend to get a higher amount of protein by using powder).
Vanilla extract or cinnamon - These make great additions to blueberry overnight oats. Add a pinch of cinnamon or ½ teaspoon vanilla extract when mixing all ingredients together.
Nut butter - I like adding 1 tablespoon of almond butter or peanut butter to the mix for extra creaminess and flavor.
How long can you keep overnight oats?
Store overnight oats in an airtight container in the fridge for up to 5 days.
Can you freeze overnight oats?
Yes, you can freeze overnight oats (although for best results eat them fresh). Thaw fully on a countertop before using. Once thawed, place in the fridge until ready to eat.
Overnight oats are good for you, containing various vitamins and minerals including magnesium, copper and iron. They also contain extra fiber and protein, and make a nutritious breakfast. Learn more about the health benefits of oats.
Any kind of oats can be used for overnight oats, including quick or instant oats. I opt for old fashioned, slow cook overnight oats as they are a little chewier
You can use steel cut oats for overnight oats, just be aware that you might end up with a slightly different texture because steel cut oats are smaller and more dense than regular ones.
Yes! Although typically eaten cold, you can warm them up in the microwave if desired. In my opinion, cold oats taste better.
