These easy blueberry overnight oats require just a few minutes of prep time. If you found this recipe, you’re probably already convinced so let’s get started!

Blueberry Overnight Oat Ingredients

You only need six simple ingredients to make this blueberry overnight oats recipe:

• Rolled oats or instant oats (quick oats)
• Fresh blueberries, frozen blueberries, or a combination if that’s what you have
• Kefir, a fermented dairy product with probiotics
• Unsweetened coconut flakes or shredded coconut
• Vanilla extract
• Cinnamon

(quantities provided in the recipe card below)

Street Smart Nutrition Tip: Kefir (pronounced “kee-fir” or “keh-fear”) adds more than just a rich, creamy texture. It’s full of probiotics that can help support better gut health. When paired with oats, a prebiotic food, it creates a symbiotic relationship that does more to benefit your gut than only having one or the other. 

If you have a bit of a sweet tooth, you can also add a little bit of maple syrup, honey, or another sweetener of your choice.

Swaps and Substitutions for Blueberry Overnight Oats

The beautiful thing about overnight oats is that they’re like a blank canvas – so easy to customize! This base recipe is meant to be simple and flexible so you can add your favorite ingredients and toppings. 

If you’re looking for some ideas, start here:

• Add some crunch with chopped nuts like almonds, pecans, or walnuts.
• Or, make your creamy oats even more decadent and filling by adding a scoop of peanut butter or almond butter on top.
• Dice a ripe banana and mix it in along with the blueberries. Or, add other types of fresh or frozen berries.
• Add some extra fiber and healthy fats in your blueberry overnight oats by including hemp hearts (hemp seeds), ground flax seeds, or chia seeds. 
• If you don’t have kefir, switch to whole milk or Greek yogurt. Overnight oats made with milk won’t be quite as thick or creamy, so reduce the amount by a tablespoon or two for better results. 

Need a dairy-free option? Look for a non-dairy kefir or dairy-free yogurt, or swap for oat milk, soy milk, almond milk, or your favorite dairy alternative.

How to Make Blueberry Overnight Oats

​When it comes to easy breakfasts, it truly doesn’t get much easier than this! Follow these simple steps to make these Blueberry Overnight Oats in less than five minutes:

1. Wash the blueberries if using fresh (no need to thaw if you’re using frozen blueberries). Grab your storage containers or a large bowl.
2. Add the blueberries along with the rest of the ingredients. Give it a good stir and lightly shake to settle.
3. Seal and store in the refrigerator for at least four hours, or overnight. 
4. When ready to serve, remove from the fridge and top with extra blueberries, coconut, or cinnamon and enjoy!

Storage and Meal Prep Tips

Overnight oats are the ultimate breakfast meal prep hack! Once everything is mixed, all you have to do is seal and store in the fridge until the next morning. 

Need some good containers? I love the Brilliance set from Rubbermaid because they come in a variety of sizes with a super tight locking seal. If you prefer a glass option, the Weck jars also come in different sizes.

Once prepared, they’ll last three to four days. Be sure to keep them chilled as a food safety precaution.

Blueberry Overnight Oats FAQs

Do overnight oats really have to chill overnight?

Conveniently, no. If you have just a few hours, these can still soften enough to be enjoyed without chewing forever. I recommend waiting at least four hours for best results.

What are the best oats to use for overnight oats?

Go with rolled oats or instant oats. Nutritionally, all oats are very similar. But these varieties will soften faster and have a more pleasant texture. Avoid steel cut oats when making any overnight oat recipe.
