I’ve been having so much fun making overnight oat recipes and this version reminds me of a blueberry muffin! I wanted to create one without chia seeds, in case you don’t have any in your pantry, so this recipe uses yogurt to thicken the oats instead of chia seeds. The yogurt is also a great way to add more protein to this oatmeal. You can even add half a scoop of protein powder to this recipe if you want to make it even more protein-packed! I don’t recommend more than half a scoop. Otherwise, the protein powder flavor tends to dominate.

Another great thing about this recipe is that you can use fresh or frozen blueberries! So no matter what season it is, you can enjoy these tasty overnight oats.

Blueberry Overnight Oat ingredients

Ingredients & Substitutions

  • Rolled Oats– Rolled oats or old-fashioned oats work best in this recipe. Quick-cooking oats tend to break down too much when sitting overnight.
  • Milk– I used almond milk, but you can use dairy, coconut, or any milk you prefer.
  • Vanilla– A little vanilla extract helps add sweetness.
  • Yogurt- I used vanilla Greek yogurt for extra thickness and sweetness. You could also use plain yogurt and adjust the sweetener to taste.
  • Salt– A pinch of salt enhances the overall flavor.
  • Berries– I used fresh blueberries but frozen works well, too.
  • Walnuts– I liked the texture the walnuts added to this recipe and it helped make the recipe more filling.
  • Granola– The additional crunch and sweetness of granola sprinkled on top reminded me of a crunch streusel topping on a muffin!

Topping Ideas

I used walnuts and granola, but you could substitute them with any nut you like! You could also add shredded coconut or even a drizzle of peanut butter or almond butter. I liked the flavor of granola and walnuts because it really reminded me of the crumbly topping on a blueberry muffin. If you need a granola recipe, try my oil-free granola, oatmeal cookie granola, or my grain-free granola. Have fun with the toppings!


Frequently Asked Questions

  • Do overnight oats have to sit overnight? No, the oats will be ready after just a few hours. But they can be soaked overnight, so you can make the oats in advance if you like. They’re a great meal prep recipe!
  • Can I use steel cut oats? No, steel cut oats don’t soften like rolled oats. But if you have steel cut oats to use, try my baked steel cut oats!
  • Can I double the recipe? You sure can! You can make a larger batch and scoop out each serving as needed or you can prepare it in separate jars.
  • Do I have to use a mason jar? No. Any small container with a tight-fitting lid, such as a Pyrex container, will work fine. You can also repurpose containers like glass yogurt or spaghetti sauce jars! While the recipe makes about 1 cup of oats, I recommend using a larger container so you can easily mix the ingredients.
  • Can I heat up my overnight oats? Yes! If you like warm oats, microwave them for a minute or two before eating them.
