Whipping up this scrumptious three-ingredient blueberry and pineapple smoothie with oat milk is an absolute breeze. It's especially delightful after breaking a sweat at the gym.

Feel free to use fresh or frozen fruit, depending on your preference or the season. I like to switch it up myself!

Most pineapple smoothie recipes I've come across call for orange juice. That's tasty but can make the drink a tad too acidic for my liking. Plus, if you're trying to cut down on sugar, orange juice-based smoothies might not be your best bet.

That's why I opted for oat milk in this pineapple blueberry smoothie. I've experimented with almond milk for a pineapple smoothie before, but I found that the oat milk smoothie has a creamier texture.

Ingredients and substitutions

Pineapple — Fresh pineapple offers a juicy and tropical taste, while frozen pineapple provides a thicker, frostier consistency to your smoothie.

If you only have canned pineapple on hand, just be sure to drain the syrup or juice before using it to avoid excess sugar.

Blueberries — Similar to pineapple, fresh blueberries will give you a vibrant burst of flavor, while frozen ones will create a thicker and more slushy-like texture.

Don't be afraid to mix it up – try raspberries, strawberries, or blackberries as an alternative or in addition to blueberries for a delightful berry medley.

Oat milk — Oat milk adds a creamy, slightly sweet taste and a velvety texture to your smoothie. If you're not a fan of oat milk, you can swap it out for another plant-based milk like almond, cashew, or soy milk.

For a nut-free option, try coconut or rice milk. To amp up the creaminess factor, you can even use Greek yogurt or a dairy-free alternative.

How to make blueberry pineapple oatmeal smoothie

Prepare your ingredients: If you're using fresh pineapple, cut it into chunks and remove the core. If using frozen pineapple and blueberries, remove them from the freezer and allow them to sit at room temperature for a few minutes to soften slightly. This will make blending easier.
Add the ingredients to the blender: Place the pineapple chunks, blueberries, and oat milk into your blender. Ensure that the ingredients are evenly distributed to facilitate smooth blending.
Blend the smoothie: Blend the mixture on high speed until smooth and creamy. You may need to pause the blender and scrape down the sides with a spatula. Add more oat milk and blend again if you prefer a thinner consistency.
Taste and adjust: Give your smoothie a quick taste to check for sweetness and consistency. If needed, adjust by adding more fruit, oat milk, or your preferred natural sweetener (such as honey, agave nectar, or dates). Blend again until everything is well combined.
Pour and serve: Pour your blueberry pineapple smoothie into a glass or a reusable container if you're on the go. Enjoy immediately for the best taste and texture.

Recipe notes and tips

For an extra protein boost, add a scoop of your favorite protein powder or a spoonful of Greek yogurt.
A handful of spinach or kale can easily be incorporated into the smoothie for an additional dose of vitamins and minerals without affecting its taste.
If you'd like your smoothie a bit sweeter, you can sweeten it naturally with honey, agave nectar, or a couple of pitted dates.
For added crunch and texture, top your smoothie with granola, chia seeds, or coconut flakes.
