This blueberry citrus smoothie blends frozen blueberries with a whole orange, banana, fresh pineapple, carrots and spinach into a thick, deep purple drink that tastes like pure fruit.

The liquid base is pure orange juice or a bottle of Naked Blue Machine, so you can make it with whatever is in your fridge. Everything goes into the blender at once and it’s ready in under a minute.

The Best Blue Machine Smoothie Recipe (Blueberry Citrus with Hidden Veggies)

A good smoothie should taste like a treat and still pack in real produce, and this one does both. Two cups of frozen blueberries give it a rich color and a sweet, slightly tart berry flavor. The orange juice and a whole peeled orange add bright citrus, while banana and fresh pineapple bring natural sweetness and a creamy, tropical body.

Then there are the veggies. A cup of baby carrots and a cup of spinach go right into the blender, and once everything is smooth you won’t spot them. The blueberries are so deeply colored that they cover up the green of the spinach, and the carrots blend into the citrus without changing the flavor much at all.

The frozen blueberries do double duty. They keep the smoothie icy cold and thick without diluting it the way a lot of ice would. If you like your smoothie even thicker, add more frozen blueberries, a frozen banana or a little ice.

Use pure orange juice for a sunny, tangy smoothie, or pour in Naked Blue Machine as the base for an extra boost of blueberry flavor. Either way it’s an easy breakfast, a quick afternoon snack or a fun way to get a little extra produce into kids who are picky about vegetables.

Ingredients You’ll Need

Here are the blue machine smoothie ingredients and why each one is there. Exact amounts are in the recipe card below.

Pure orange juice or Naked Blue Machine: The liquid that gets everything moving in the blender. Pure orange juice adds bright citrus flavor. Naked Blue Machine is a bottled blueberry juice smoothie, and it deepens the berry flavor and color. Choose 100% juice with no added sugar if you go the orange juice route.
Orange: A whole peeled orange adds fresh citrus flavor plus the fiber you lose with juice alone. Pull off as much of the white pith as you can, since it can taste bitter.
Banana: Makes the smoothie creamy and naturally sweet. A ripe banana with brown speckles is sweetest. Use a frozen banana if you want the smoothie extra thick and cold.
Fresh pineapple chunks: Add tropical sweetness and a little tang that pairs well with orange. Fresh pineapple is juicier and brighter than canned. Frozen pineapple chunks are a handy swap and make the smoothie thicker.
Baby carrots or a carrot: Add a mild sweetness and a boost of vegetables. Baby carrots are already peeled and easy to measure. If you use a regular carrot, peel it and cut it into chunks so it blends smoothly.
Spinach: Mild in flavor, so it disappears into the fruit. Baby spinach is the most tender and blends the smoothest. Frozen spinach works too and makes the smoothie even colder, so you may need a splash more juice.
Frozen blueberries: The star of the smoothie. They provide the deep purple color, the berry flavor and the thick, frosty texture. Frozen berries are picked ripe and are available all year, and they make ice almost unnecessary.

How to Make a Blueberry Citrus Smoothie

Prep the produce. Peel the orange and banana, cut the pineapple into chunks and peel the carrot if you’re using a regular one. Rinse the spinach and shake off the extra water. Having everything ready before you start means the frozen blueberries won’t thaw on the counter while you work.
Add the liquid first. Pour the orange juice or Naked Blue Machine into the blender. Liquid on the bottom helps the blades spin freely and pull everything else down.
Layer in the rest. Add the orange, banana, pineapple, carrots, spinach and frozen blueberries, in that order. Soft fruit and greens go in before the frozen berries, so the heavy frozen fruit sits on top and pushes everything into the blades.
Blend. Blend for 30 to 45 seconds, until completely smooth. You shouldn’t see any flecks of spinach or bits of carrot, and the color should be an even, deep purple. If the blender stalls, stop and stir, or use the tamper if your blender has one.
Adjust the thickness. For a thicker smoothie, add more frozen blueberries, a frozen banana or a handful of ice and blend again. For a thinner smoothie, add a splash more juice.
Serve. Pour into glasses and enjoy right away, while it’s cold and frosty. Smoothies start to separate as they sit, so this one is best the moment it comes out of the blender.

Kami’s tip: Add the ingredients to your blender in the order they are listed, then blend for 30 to 45 seconds. Want it thicker? Toss in more frozen blueberries, a frozen banana or ice.

Ways to Customize This Smoothie

Switch the base. Use pure orange juice or Naked Blue Machine, depending on which flavor you prefer.
Make it thicker. Use a frozen banana or extra frozen blueberries.
Swap the greens. Use baby kale instead of spinach for a slightly earthier flavor.
Add protein. Blend in a scoop of Greek yogurt or your favorite protein powder.

Blueberry Citrus Smoothie FAQs

What is Naked Blue Machine? It’s a bottled blueberry juice smoothie from Naked Juice. In this recipe it can replace the orange juice as the liquid base. Check the bottle label for its exact ingredients.
Can I taste the spinach and carrots? Not really. The blueberries, orange and pineapple are much stronger in flavor, and the deep purple color hides the greens.
Do I need a high powered blender? A Vitamix or other high powered blender gives the smoothest result, especially with carrots. With a regular blender, chop the carrots small and blend a little longer.
Can I use fresh blueberries? Yes, but add a handful of ice or a frozen banana so the smoothie stays thick and cold.
Why is my smoothie too thick to blend? Frozen fruit can jam the blades. Add a splash more orange juice or Naked Blue Machine, stir and blend again. A tamper also helps push the frozen berries down.
Can I make it ahead? It’s best fresh. You can keep it covered in the fridge for up to a day. Shake or stir before drinking, since it will separate.
Can I leave out the banana? Yes. The smoothie will be a little less creamy and sweet, so add a few extra frozen blueberries or pineapple chunks to keep it thick.
