Cucumber Blueberry Smoothie: 5-Minute Recipe

DetoxWater Editorial Team•Published November 5, 2026

A cucumber blueberry smoothie is a blended drink made with cucumber, blueberries and water that takes 5 minutes to prepare and yields 2 servings.

It has a mild cucumber flavor and a tart, fruity finish. For a cucumber-forward alternative, see the cucumber detox smoothie.

What ingredients do you need?

  • 150 g cucumber (about 1¼ cups chopped): Use raw cucumber with the peel on.
  • 150 g blueberries (about 1 cup): Use fresh blueberries or unsweetened frozen blueberries.
  • 240 ml water (1 cup): Use cold water for a chilled smoothie.

The cucumber adds a light, fresh flavor, while the blueberries provide sweetness and color. Keeping the cucumber peel and blending the whole fruit means the finished drink retains their fiber.

Choose a cucumber with firm skin and rinse it under running water. Rinse fresh blueberries just before using them; frozen berries can go straight into the blender. The nutrition estimate below is based on raw cucumber and fresh blueberries.

How do you make a cucumber blueberry smoothie?

  1. Rinse the cucumber and fresh blueberries under running water. Trim the ends of the cucumber and chop it into pieces that your blender can handle.
  2. Add the cucumber, blueberries and water to the blender. Put the water in first if your blender needs help moving the ingredients.
  3. Blend until smooth, stopping to scrape down the sides if needed. Add a little more water and blend again if you prefer a thinner drink.
  4. Divide between 2 glasses and serve immediately.

There is no steeping time: this is a blended smoothie, not infused water. If you make it ahead, refrigerate it promptly in a covered container and drink it within 24 hours for best flavor. Stir or shake before serving if it separates.

Does a cucumber blueberry smoothie support detox?

The cucumber blueberry smoothie can contribute fluid to your day, but it does not remove toxins or replace the body's own processes. The liver and kidneys do most of the work of processing and removing waste; the lungs and gut also help eliminate waste.

Cucumber and blueberries contain water, and the added water provides more fluid. Blending rather than straining also keeps the ingredients' fiber in the glass. Fiber supports regular digestion, although this smoothie is not a treatment for digestive problems.

Blueberries provide vitamin C and naturally occurring plant compounds. Those nutrients are part of a varied diet, not evidence that this particular smoothie has a special detox effect. For another way to use the fruit, see the blueberry detox smoothie.

What swaps and variations can you try?

Use frozen blueberries

Unsweetened frozen blueberries make the smoothie colder and thicker without adding ice. They may also make the blender work harder, so start with the water and stop to scrape down the sides if necessary. Use the same weight as in the base recipe.

Change the texture

For a thinner drink, blend in a little extra water. For a thicker texture, use less water at first and add more only as needed. A longer blend can help break down the cucumber peel, though the texture depends on your blender.

Make it creamier

Replace some of the water with plain yogurt if you enjoy a creamier smoothie. Yogurt adds protein as well as changing the flavor and texture. The nutrition estimates below no longer apply if you make this swap.

What is the nutrition per serving?

These estimates are for one of 2 equal servings, made with the listed amounts of raw cucumber with peel, raw blueberries and water. They are calculated from USDA ingredient data, not from a laboratory analysis of the finished drink.

The sugars occur naturally in the cucumber and blueberries; the base recipe has no added sugar. Actual values will vary with the produce, how much you use and any substitutions. Because the ingredients are blended rather than steeped and discarded, the calculation includes the whole cucumber and blueberries.

Frequently asked questions

Does a cucumber blueberry smoothie need ice?

No. Cold water or frozen blueberries can chill it without ice.

Why did my cucumber blueberry smoothie separate?

The blended solids can settle as the smoothie sits. Stir or shake it before drinking.

Can I use a food processor instead of a blender?

Yes. Process the ingredients until as smooth as possible, though the texture may be less uniform than with a blender.
