Wild Blueberry Oatmeal Smoothie Recipe

This Wild Blueberry Oatmeal Smoothie tastes like a blueberry muffin but is the most delicious blended drink ever. It’s thick, creamy, and loaded with bold, jammy wild blueberry flavor.

I love smoothies like this because they’re another way to enjoy breakfast staples you probably already have on hand. Instead of a bowl of oatmeal and a banana, you can blend them into a protein-filled smoothie that’s quick, nutritious, and still feels like a treat.

Blended up, it turns a gorgeous deep purple and smells like fresh-baked muffins.

It’s hard to believe it’s made with such simple ingredients: fruit, oats, yogurt, and milk. No protein powder required (though you can add some if you’d like).

What Are Wild Blueberries?

Wild blueberries grow naturally in parts of the eastern United States and Canada.

Unlike larger, cultivated blueberries, wild ones are tiny, tangy, and packed with antioxidants. They’re almost always sold frozen, which makes them perfect for smoothies.

I grew up in Connecticut where we had a single wild blueberry bush in our yard.

Some summers I’d eat the berries straight from the bush before anyone else had a chance. Other years I’d try to save the tiny harvest for a recipe.

If only blended smoothies were a thing back then. This wild blueberry oatmeal smoothie would’ve been high on my list.

The bag you see in my photo is from Trader Joe’s. Their frozen wild blueberries are my favorite: organic and usually cheaper per ounce than other brands. A 12-ounce bag runs about $3, and I keep them stocked in my freezer.

Why You’ll Love This Wild Blueberry Smoothie

Tastes like a blueberry muffin – Oats, vanilla, and cinnamon give it that cozy, baked-good flavor.

High in protein – Greek yogurt, oats, and milk add almost 23 grams of protein, no powder needed.

Naturally sweet – Ripe banana and blueberries mean no added sugar.

Thick and creamy – Frozen banana + frozen blueberries = no ice cubes required.

Filling and satisfying – Keeps you going all morning.

Ingredients Needed

• Frozen wild blueberries
• Frozen banana
• Rolled oats
• Greek yogurt
• Milk
• Vanilla extract
• Ground cinnamon
• Pinch of salt

Wild blueberries – Buy bags of frozen wild blueberries; they’re rarely sold fresh. If you live where they’re grown, you might spot them at a farmers market.

Banana – Use very ripe, frozen banana slices for creaminess and natural sweetness. I always keep a stash of pre-sliced chunks in the freezer and never waste an overripe banana.

Rolled oats – Stick with rolled oats; steel-cut won’t blend as smoothly.

Greek yogurt – A protein powerhouse that adds creaminess and tang.

Milk – I like filtered milk (such as Fairlife) because it’s lactose-free and has more protein per cup.

Vanilla, cinnamon, and salt – Don’t skip this trio! Together they make the smoothie taste like a blueberry muffin.

Protein Tip
This smoothie gets its protein naturally from Greek yogurt, milk, and oats—no powder required. Using filtered milk (like Fairlife) boosts it even more. Want more high-protein smoothie ideas? Check out my Peanut Butter Banana Protein Smoothie for another filling, protein-packed option.

How to Make a Wild Blueberry Oatmeal Smoothie

Detailed recipe and instructions are in recipe card at bottom of post.

1. Add rolled oats, cinnamon, and salt to the blender. Blend for about 10 seconds to break down the oats.
2. Add wild blueberries, banana, Greek yogurt, milk, and vanilla.
3. Blend until thick and creamy. I use the smoothie button on my Ninja personal cup blender (no pricey high-speed blender needed).
4. Taste and adjust. Add more milk if it’s too thick.
5. Pour into a glass and enjoy right away.

Why Two Frozen Fruits?
Frozen banana + frozen blueberries = thick, creamy texture with no ice cubes to water it down.

Nutrition Highlights

When made with non-fat Greek yogurt and non-fat filtered milk, this 16 oz smoothie has:

• 340 calories
• 22.8 g protein
• 8 g fiber
• 28 g natural sugars (none added)

It’s a great balance of protein, fiber, and antioxidants; exactly what I want in a breakfast smoothie.

Blueberry Smoothie Without Banana

Want fewer calories and sugars? Skip the banana and use 1 full cup of wild blueberries instead. The smoothie will be 275 calories with 21.5 g sugars.

How to Make a Blueberry Oat Smoothie Freezer Pack

Add oats, cinnamon, and salt to a small snack-size bag. Place that inside a larger sandwich-size freezer bag along with the frozen banana slices and wild blueberries.

To freeze your own fruit, lay banana slices or berries in a single layer on a tray for 30 minutes before transferring to the bag. This prevents clumping and makes blending easier.

I usually prep a few at once so I have grab-and-blend breakfasts ready for the week.

Freezer Pack Blending Directions
When you’re ready to make a smoothie, pour the oats, cinnamon, and salt from the dry bag into the blender and blend for 10 seconds. Then add the frozen fruit and the liquid ingredients. Blend until smooth.
