These no cook blueberry overnight oats satisfy all of my oatmeal cravings without having to cook over a hot stove.

In Fresno, it gets REALLY hot during the summer months. With summer inching closer and closer I do not want to have to give up oatmeal for breakfast!

Why I love overnight oats:

  • They are convenient – take with you on the go.
  • Easy to prep before bed, and easy clean up!
  • Provide fiber and can be heart healthy
  • SUPER delicious!
  • Can be eaten cold, or warmed up.
  • Flavor and varieties are endless!

What you’ll need:

  • Oats: You can make them with either the old-fashioned rolled oats or the quick oats. I have made them both ways for this recipe and love both. It comes down to preference (most recipes use old-fashioned rolled oats NOT the quick 1 minute).
  • Milk: Any milk! Cows milk, soy milk, almond milk, etc. Use non-dairy for vegan option.
  • Greek yogurt: helps to make these oats nice and creamy. Also adds a boost of protein. Feel free to use a flavored yogurt if you prefer. We usually opt for plain!
  • Blueberries, of course. You can use frozen, too!
  • Honey or maple syrup: It adds a yummy touch of sweetness but you can leave out if you prefer. Use maple syrup for vegan option.
  • Chia seeds: I love how the chia seeds thicken the texture of the oats. You can also use flaxseed if you don’t have chia, or add in both!
  • Vanilla extract: I always add a teaspoon in my overnight oats because I love the hint of vanilla flavor.
  • Cinnamon and salt: a dash of cinnamon and salt for a little extra flavor.

My overnight oats formula:

  • 3/4 cup milk
  • 1/2 heaping cup old fashioned oats
  • 1/3 cup Greek yogurt
  • 2 tsp chia seeds
  • 1 tsp. honey and vanilla
  • pinch cinnamon and salt
  • (+ any mix ins you want!) In this case, blueberries!

Step by Step directions:

It’s really simple:

  1. Pour all of the ingredients into a mason jar or small bowl.
  2. Stir to combine and pop a lid on.
  3. Place in the fridge for at least 3 hours or overnight!


What type of oats are the best oats to use for overnight oats?

The best oats to use, in my opinion and many other overnight oat aficionados, are old-fashioned rolled oats.

Steel cut oats can be used but be prepared for a chewier texture and you may want to add a few tablespoons more milk. The steel cut oats won’t break down as much as the rolled oats which is why you don’t see them used in many recipes.

Instant oats however will break down very fast and after sitting overnight in the fridge they tend to disintegrate completely into the milk. They work, but result in a less creamy overnight oatmeal texture.

Do I really have to wait overnight until I can eat the oats?

Not necessarily! I have personally found at least 3 hours of fridge time is plenty.

Do I have to use plain Greek yogurt?

Nope! This recipe would be great with a blueberry yogurt or vanilla yogurt. This recipe is flexible, choose your favorite brand and flavor.

Do I have to use a jar?

Any bowl or container works well. I find a wide mouth jar works really well for preparing and eating the oats.

Topping ideas:

You can top with nuts, nut butter, more chia seeds, ground flaxseed, more honey, more blueberries or even other fruit like strawberries or bananas.

I love the versatility of the product and how it is an easy swap for dairy – I have enjoyed putting it in my coffee, smoothies and in overnight oats!

Pro tip: In the morning when you are ready to enjoy your oats – add in more milk if you feel like the oats soaked up all of the liquid! Add your additional toppings and you’re set!
