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. You make them by mixing rolled oats with milk and other ingredients in a jar and leaving the mixture to soak in the fridge overnight. In the morning you can eat it straight from the jar or in a bowl topped with fresh fruit, nut butter, or other toppings.
Rolled oats are naturally gluten-free so this recipe can be both gluten-free and vegan! If you need to, make sure your oats are certified gluten-free to make sure they're not made in a facility that processes wheat.
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 + mango + honey + lime zest
- blueberries + ginger + orange
- blueberries + peaches + vanilla + cinnamon
- blueberries + apples + cinnamon + vanilla
- blueberries + raspberries + Greek Yogurt
Overnight Oats FAQ:
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.
Either work, use what you have on hand. I usually use frozen when it's berries and fresh when it's anything I need to chop up. I prefer to use frozen wild blueberries in this recipe.
1:2 is a great simple ratio to start with. Adjust this to your liking - thicker oats will need less milk and adding chia seeds will require more. I add 3 tbsp milk for every 1 tbsp chia seeds. For my overnight oats I mix 1/2 oats with 3/4 cup milk.
Yes, you can eat overnight oats both cold and warmed up. I prefer cold to save time. If I want warm oats, I choose oatmeal instead.
Pro Tip: Avoid warming up oats with chia seeds, they taste the best cold.
I recommend always prepping these the night before. The oats will keep well but the fruit doesn't usually stay fresh for very long. The recipe will taste the best made fresh but if needed, it will keep for 2-3 days in an airtight container in the fridge.

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.
