These super creamy and easy blueberry overnight oats are bursting with flavor and packed with not only vegan protein, but nutrients as well for a filling and delicious healthy breakfast!

Healthy Blueberry Overnight Oats (Vegan, Gluten Free)

Vegan Overnight Oats Basic Ingredients

You can completely customize these blueberry overnight oats to be whatever you’d like (more on that below), but here are the basic ingredients and ratios that you’ll need to make the best creamy vegan overnight oats.

Keep in mind that the full recipe is found down below in the recipe card. However, we’ll go over an overview here!

For this super easy and meal prep-able healthy breakfast, you’ll need:

  • Rolled oats: I talk about this later, but rolled oats over quick or steel cut is really the move.
  • Creamy dairy free milk: I emphasize creamy here because sometimes refrigerated almond and even some coconut milks can be a bit watery. I recommend using a full fat oat milk, cashew milk, or a really high quality coconut milk (I prefer Califia’s here!).
  • Chia seeds: this not only helps the overnight oats to “grow” in size (you get a much greater volume the next day!), but chia seeds also offer wonderful fiber, omega-3’s, and antioxidants.
  • Sweetener: I use maple syrup, but you can use agave, or if you’re not vegan, honey.
  • Blueberries: fresh or frozen berries work here!
  • Pea protein: my favorites are Nuzest vanilla pea protein or Terrasoul unflavored. The type of protein brand you use is key because that can either add to or take away from the taste of the oats. Choose one you really like!
  • Vanilla extract: adding a bit of extract in here makes these vanilla overnight oats taste like actual dessert!

Now for the ratios. How much milk should you use in overnight oats? I recommend doing 1/2 cup oats and 3/4 cup milk (so about 1:1.5). This helps the oats to soften over time and also absorb the liquid.

Of course, I’m sure you know the basics of making overnight oats, but if you want to know my tricks for ensuring you’re making delicious overnight oats each time, read on!

The full recipe is down below in the recipe card; however, I’ll go over some tips here!

  • Whisk together the dry ingredients: the oats, chia seeds, and protein powder should be completely whisked together. You can use a fork here, and actually just whisk it in your jar or bowl. this helps make sure there aren’t any clumps of protein powder. Ick!
  • Add in the wet ingredients: and then just mix everything around! Make sure to scrape the crevices of the jar to make sure no protein powder is getting stuck there.
  • Cover the oats: you want the oats to stay fresh until the morning!
  • Stir in a few tablespoons of extra milk to help everything get moving!
  • Top and enjoy!

How to meal prep overnight oats

If you don’t just want to make one serving of these oats, but rather prep them for the entire week, you can easily add this recipe to your Sunday meal prep routine.

To make enough oats for 5 breakfasts throughout the week, you can easily scale this recipe up and make either a big batch in a large bowl or make 5 individual glasses that are easily transported.

And the best part is that you can switch up the toppings for your blueberry overnight oats each day too, so that it feels like you’re having a different breakfast each day!

Do I eat overnight oats cold?

Yes! The beauty of overnight oats is that there’s no cooking required. Just mix everything together, and let the fridge do its magic.

However, if it’s really chilly where you are when you’re making these blueberry overnight oats, you can absolutely heat it up in the morning for about a minute in the microwave.

How long do overnight oats last in the fridge?

If you’re making these blueberry overnight oats for a meal prep breakfast, you can store these oats made in their separate jars for up to 5 days in the fridge!

Please keep in mind that you should cover these oats tightly in order to keep their freshness over a few days in the fridge.

Customizing this oats recipe

The beauty about these vanilla blueberry overnight oats is that it’s a highly customizable recipe.

While this is already a vegan overnight oats recipe, so no need to adjust for anything there, we can customize for the flavor (and even texture!) combinations:

  • Use dairy free yogurt for a slight tang. I love adding a bit of coconut milk yogurt to my oats. It makes them super creamy and taste a bit like cheesecake! Again, even healthy overnight oats can taste like dessert!
  • Switch up the dairy free milk. And by that, I mean the flavor! If you have a favorite chocolate dairy free milk, add a splash of that in place of the regular vanilla creamy drink for a fun twist.
  • Add in cacao powder. I love chocolate and berries. My personal favorites are blueberries and chocolate and raspberries and chocolate (strawberries and chocolate are ehh, but it’s growing on me). Stir in 1 tsp cacao powder to the dry ingredients!
  • Toppings: my absolute favorite part! You can still have healthy overnight oats with your favorite toppings. I love to add chopped hazelnuts with the blueberries- it’s such a wonderful taste combination. You can also do seeds if you’re nut free, or even granola! Sprinkle on some chocolate chips to your vanilla blueberry overnight oats for a bit of chocolate in there as well!
  • Sweeteners: if you don’t want to sweeten your oats with a syrup, you can add in 1/2 mashed banana for a no-added-sugar trick to your oatmeal (yes, technically fruit is sugar, but most don’t consider it an added sugar if it’s coming from the whole plant). You can also use agave if you’d like or honey if you’re not vegan.

My favorite tips & tricks for making overnight oats

I know, I know, overnight oats is not a difficult recipe to make. But texture is everything when it comes to oatmeal in general, and I’ve been doing the whole overnight oats thing for about 12 years now. I’ve picked up a few tricks that ensure I’m getting the best flavored and textured overnight oats every time!

Use vanilla extract or paste. Trust me, this will make your vanilla overnight oats taste like a dessert rather than a boring healthy breakfast (for the record, I don’t think healthy tastes boring, but let’s be real: if we don’t put any effort into our oatmeal bowls, they do taste a bit bland!). This is a game changer. Trust me!

The creamier the dairy free milk, the better. I prefer to use either coconut milk or oat milk for these overnight oats. Store bought almond milk seems to not give it as creamy of a texture. You could also use cashew milk here, but if you’re nut-free, stick to oat or coconut for the creamiest vegan overnight oats!

The protein powder choice is crucial. A bad tasting protein powder will yield not-so-great overnight oats. I personally recommend using either Nuzest (the vanilla flavor is amazing!) or Terrasoul unflavored pea protein. Those seems to taste the best to me (or have no effect on the taste of these protein overnight oats!). I did recently discover a new pea protein brand called Tejari, but I’ve yet to try them! They look promising though!

Use rolled oats and not quick oats. The same goes for using steel cut oats. Your blueberry overnight oats will either be too soft or not soft enough when using either quick oats or steel cut oats. Out of the three kinds of oats, I highly recommend just using rolled oats!

Make it gluten-free if needed. While oats are technically naturally gluten free, there is always the potential it could be cross-contaminated when not specifically certified gluten free. You’re going to want to look for that gluten-free certification if you are high allergic to gluten!
