Why You’ll Love it:

Blueberries are one of my favorite additions to smoothies, and this blueberry oatmeal smoothie is perfection! It’s hearty and filling from the oats, yet sweet from the juicy bluebs.

It makes a great breakfast smoothie because it has all the things – protein, fiber, healthy fats, and essential vitamins.

And don’t underestimate the nutritional power of blueberries! They’re packed with fiber, vitamins, and powerful antioxidants. Antioxidants protect your healthy cells from free radical damage. Win, win!

Oats in Smoothies:

Rolled oats are a nutritious and filling addition to smoothies! They add a slight texture and subtle oatmeal flavor.

They’re a good source of:

  • Soluble fiber
  • Plant-based protein
  • Whole grains.

And they’re versatile too! I put them in all kinds of smoothies – berry, chocolate, green, and tropical.

If you don’t like texture in your smoothies, I would either skip the oats OR use less to start with. Try a couple tablespoons and see how you like the taste/texture, then add more as desired.

Key Ingredients:

This blueberry oat smoothie is just 5 ingredients!

banana, frozen blueberries, oats, yogurt, apple juice.
  • Banana – For a creamy consistency! Both blueberries and oats add texture, so the banana keeps it nice and creamy. Use a ripe banana for natural sweetness.
  • Greek yogurt – For a boost of protein and creaminess. I prefer to use plain Greek yogurt to avoid extra sugar. You can use sweetened if you prefer.
  • Oats – Be sure to use rolled oats. Quick oats also work, but they absorb more liquid and thicken the smoothie. You can compensate by adding more liquid.
  • Frozen blueberries – I buy a big bag of organic frozen blueberries at Costco! It’s important to use frozen fruit to achieve a thick, frosty consistency. Fresh blueberries turn into pulpy juice.
  • Apple juice – I use a splash of apple juice for sweetness! Apple juice and blueberries pair so well together. And you don’t need much to sweeten it up.

How to Make a Blueberry Oatmeal Smoothie:

This blueberry smoothie is super simple (as always!).

  • Combine ingredients: In a high-speed blender, combine all the ingredients. I always start with the soft ingredients (i.e. banana and yogurt) to give the blades something to catch.
  • Blend: Turn the blender on low, then increase the speed to high. Blend until smooth-ish. The oats DO add some texture.
  • Adjust: Check for taste and consistency. If the smoothie’s too thick to pour, add a splash more liquid and blend to incorporate.
  • Serve: Pour into glasses and enjoy right away!

Variations & Substitutions:

  • Fruit – You can swap the frozen blueberries with frozen mixed berries, strawberries, or mango!
  • Protein powder – For a boost of protein, add 3 tablespoons of vanilla protein powder.
  • Juice – You can swap the apple juice with white grape or passion fruit juice. Look for brands that are 100% juice without added sugar.
  • Oats – If you don’t like texture in your smoothies, you can omit the oats or decrease the amount to 2 tablespoons.
  • Greens – For a boost of iron and micronutrients, add a handful of baby spinach!
  • Dairy-free – Omit the Greek yogurt or swap it with a dairy-free/vegan alternative.

Expert Tips:

  • Use a high-speed blender. Both oats and blueberries add texture to smoothies. A high-speed blender will give you the smoothest results! The better your blender, the less texture you’ll get.
  • Start with the soft ingredients. Add the banana first. It gives the blades something to catch and reduces stalling.
  • For less texture, use less oats. If this is your first oatmeal smoothie, decrease the amount to 2 or 3 tablespoons. If you like the texture, add more as desired.
  • Adjust the consistency as needed. If the smoothie is too thick, add more liquid. It should be thick yet pourable!

Oatmeal smoothies are best enjoyed immediately! I don’t recommend storing this one in the fridge overnight.


Is it okay to put raw oats in a smoothie?

Yes! Rolled oats taste great in smoothies! They add a little bit of texture, oatmeal flavor, and plant-based protein and fiber. Technically, raw oats have been cooked during processing, just not boiled. They’re heated and rolled to make them thin and flaky.
