As a dietitian, I’m all about a balanced breakfast to start the day fueled and energized. As a busy mom, let’s be real – I love convenience. And this is why overnight oats will always be one of my (and my family’s!) favorite breakfasts! They’re delicious, quick to prep, ready to grab-and-go in the mornings, and incredibly nourishing and satiating!

Reasons You’ll Love This Breakfast:

• Meal Prep-Friendly – overnight oats are elite for meal prep! A few minutes of prep, then boom, done!
• High Protein – while exact nutrition info varies based on specific ingredients you use, mine clock in at 37 grams of protein per serving!
• High in Fiber – I always add both chia seeds and flax seeds to my overnight oats, for an extra boost of fiber and heart healthy fats. Add their fiber to that in the oats and blueberries, and you’ve got a whopping 14 grams of fiber in one convenient breakfast!
• Delicious – if you love blueberries, you’ll love these!
• Family-Friendly – my kids love overnight oats! Note that I usually omit or decrease the protein powder for theirs (simply because they have smaller bodies and lower needs in general).

Ingredient Notes & Substitutions:

For a full ingredient list with quantities, please check out the recipe card at the bottom of this post.

• Blueberries – I love to use frozen blueberries that have been thawed, as it makes the berries juicier and slightly intensifies the flavor. You can certainly use fresh, too!
• Oats – I recommend old-fashioned oats to give the best texture with the liquid ratio in these overnight oats.
• Greek Yogurt – I use a no added sugar, vanilla, fat-free Greek yogurt to keep sugar lower and add more protein and flavor.
• Milk – you can use whichever milk you prefer; I enjoy using Fairlife or another ultra-filtered fat-free milk that’s higher in protein and lower in natural sugars.
• Chia Seeds – high in fiber and heart healthy fats, these little seeds absorb liquid, which help create the almost pudding-like overnight oats texture.
• Flax Seeds – I like to add both flax seeds and chia seeds, as it adds more fiber, more healthy fats, and helps contribute to the overall stellar macros of this breakfast.

How to Make Blueberry Overnight Oats

For complete instructions, please check out the recipe card at the bottom of this post.

In my blueberry overnight oats, I blend blueberries with Greek yogurt and milk for a blueberry flavor that’s fully infused through every bite.

Pour the blueberry liquid over the dry ingredients, then whisk, set aside, whisk again, and store overnight.

Tips and Variations

• Whisk, Set, Whisk Again – if you find your oats and seeds settling at the bottom of your overnight oats, you can’t skip this step! Whisk all the ingredients together, let them set for 5 minutes, and then give one more whisk before storing in the refrigerator.
• Gluten-Free – blueberry overnights are easily gluten-free, just make sure to use certified gluten-free oats if you need them!
• Dairy-Free – use your favorite plant-based milk and Greek-style yogurt alternative. Make sure your protein powder is dairy-free, too!
• Add Different Fruits – take a play from my strawberry blueberry overnight oats and use a combo of fruits to vary up the flavor.
• Try Chocolate Protein Powder – I’m personally a huge fan of blueberries and chocolate together and love these overnight oats made with chocolate protein powder, too!

Blueberry Overnight Oats Toppings

Overnight oats are the perfect vessel for adding toppings that can add more fun, flavor, texture, and even nutrition! Some awesome toppings for blueberry overnight oats include:

Overnight Oats Storage Tips

Overnight oats are fantastic to meal prep, but you’ll want to make sure you store them correctly. Store in a covered, airtight container in the refrigerator for up to 3-4 days.

Alternatively, you can also freeze overnight oats, too! Be sure to give them a good stir once thawed. You may need to add an extra splash of milk, too, if they’ve thickened too much for your liking.
