Blueberry Oatmeal Smoothie Recipe- A Healthy Snack!

This Blueberry Oatmeal Smoothie tastes just like a blueberry pie! Make this as a cool treat during a hot Summer day!

During the Summer months, I LOVE making smoothies! They’re a great way to cool off and add extra nutrients to my diet when it’s too hot to eat.

I also like adding a tiny bit of vegetables into my daughter’s smoothies when she isn’t looking… because hopefully she’ll grow out of the picky phase, right?

What makes this smoothie healthy

Smoothies are one of the best meals to make healthy because of all the ingredients you can add to it! Here are the benefits of each of the ingredients:


Blueberries are one of my favorite fruits in the Summer! They’re cheap and can be easily frozen for later.

You get a good source of fiber, Vitamin C, Vitamin K, and potassium from these little berries. Blueberries are also high in antioxidants, which help protect the body!

Almond milk

Unsweetened almond milk has fewer calories than dairy milk and is a great non-dairy alternative for smoothies.

It’s a good source of calcium, and some types have been fortified with extra vitamins. And almond milk has a little bit of fat, which helps keep you full longer.


Oats are a powerhouse of nutrition and have so many health benefits! They’re a great source of fiber and plant-based protein, both of which increase satiety. They also help lower cholesterol and the risk of heart disease, and easy to eat every day for breakfast or even adding in smoothies.

Flax seed

I was recently introduced to flax seed and use it in almost everything now! Ground flaxseed is a great source of protein, fiber, and Omega 3 fats. Omega 3 fats are something we don’t get a lot of, but it’s super important for heart health.

I add a tablespoon of flax to my oatmeal, in my smoothies, in baked goods, pancakes… it really has no taste and doesn’t effect the texture, so there’s no reason not to add it for an extra nutrition boost!

Maple syrup

Maple syrup is a natural form of sugar. It has a tiny bit of extra nutrients than regular sugar, and I think it’s sweeter. Using a small amount in a smoothie increases the sweetness!

Other additions/substitutions

There are plenty of ways you can customize this blueberry oat smoothie!

  • Milk: Any liquid will work- oat milk, cashew milk, coconut milk, cow’s milk, water, etc.
  • Greek yogurt- for some extra protein!
  • Blueberries: Fresh blueberries are fine, but using frozen blueberries will help you use less ice!
  • Other fresh fruits
  • Vegetables: I like to add a handful of spinach!
  • Frozen banana: This adds lots of creamy texture to the smoothie and you won’t need ice! Freeze extra ripe bananas for extra sweetness.
  • Oats: You can use rolled oats or quick oats in this.
  • Chia seeds: Similar to flax, chia seeds are high in protein, fiber, and Omega 3 fats!
  • Scoop of protein powder: Chocolate or vanilla protein powder would be delicious in this!
  • Peanut butter or seed butter

Can you freeze smoothies?

I’ve frozen smoothies using two methods: The ingredients, and the full smoothies. Here’s how I do it:

Freezing smoothie ingredients

You can freeze most smoothie ingredients in a freezer-safe bag! A sandwich-size bag would work, but quart-sized might be better if you like large smoothies.

I recommend not adding the liquid until you make the smoothie in the blender. One benefit of freezing the ingredients is that you may not need as many ice cubes, thus keeping the smoothie from watering down!

Freezing whole smoothies

On mornings that I work out and don’t want to wake the house with a loud blender, I’ll make up a couple smoothies ahead of time for a quick breakfast.

Usually I’ll make a double serving and pour them into two glass Mason jars, and place them in the freezer with no lids. If you add a lid, make sure there’s room for the smoothie to expand in the Mason jar! Otherwise it may crack or explode in the freezer and you’ll have a huge mess.

The advantage of doing this is you’ll have the smoothie ready to go!

The disadvantage is it takes a long time for the smoothie to defrost. You can place it in the fridge overnight, or put the frozen smoothie on the kitchen counter while you work out and hope it’s defrosted enough to drink.

I love how this smoothie tastes a lot like a blueberry pie! It’s a fantastic way to use up leftover blueberries. Print the recipe for this creamy blueberry oatmeal smoothie:
