These delicious Blueberry Overnight Oats are the perfect breakfast for those mornings when you have no time to cook or want to take your breakfast with you! These take only 5 minutes to prep!
What are overnight oats?
Overnight Oats are an easier version of oatmeal, usually served cold. It doesn't involve any cooking. All you need to do is add some oats, milk, and flavors into a jar, mix it all up, and leave it in the fridge overnight. When you wake up in the morning, your breakfast is already ready for you! So easy!
Rolled oats are naturally gluten-free but if you have an allergy, make sure to check they're certified gluten-free.
Pro tip: Use oat milk to make this recipe nut-free!
What kind of Blueberries Should I use?
You can use both fresh or frozen, depending on what you have on hand. I recommend using organic berries whenever possible.
- fresh blueberries
- frozen blueberries
- wild blueberries
My favorite are wild blueberries! They tend to have a higher amount of vitamins and antioxidants, and they give the oats amazing vibrant purple color! I buy them frozen at a local grocery store.
There are countless ways to add even more flavor to these Blueberry Overnight Oats! Here are a few of my favorites to get you inspired.
- blueberries + peaches + vanilla + cinnamon
- blueberries + apples + cinnamon + vanilla
- blueberries + raspberries + Greek Yogurt

Oatmeal is made with oats and milk or water on the stove. Overnight oats are oats and milk mixed in a jar and soaked overnight. The cooking process makes oatmeal creamier than overnight oats.
For just oats and milk, the best ratio is 1:2, one part oats, two parts milk. If you add chia seeds, you will need to add a little more liquid.
Both work great. Frozen fruit will defrost in the oats overnight so you don't have to worry about eating frozen fruit in your oats.
Yes! You can eat these both cold and warm. Avoid warming them up if you added chia seeds, they usually don't taste good warm.
Delicious make-ahead breakfast for busy mornings.
- ½ cup rolled oats (certified gluten-free if necessary)
- ¼ tsp cinnamon (optional)

- ½ tsp vanilla extract
- ½ tsp fresh orange zest
- ¼ cup freshly squeezed orange juice
- ½ cup regular or wild blueberries (fresh or frozen)
- Optional add-ins: 1 tablespoon chia seeds(add +/4 cup if adding), yogurt, peaches, mango, or strawberries, or mashed banana
- For serving: fresh berries, hemp seeds, nut butter, yogurt, slices of orange
- Add the rolled oats, cinnamon, milk, maple syrup, vanilla extract, orange zest, orange juice, and stir well.
- Add the blueberries and stir again.
- Cover with a lid and let soak in the fridge overnight.
- Serve cold topped with more berries, hemp seeds, and nut butter, or yogurt if desired. See notes for serving the oats warm.
If you’re using frozen blueberries, only use a scant 1 cup of milk because the frozen berries will release some liquid as they defrost.
If you’re going to warm up the overnight oats in the morning, I recommend skipping the chia seeds. They turn the oats into more of a pudding and they don't taste as good when warmed up.
