Why This Cucumber Smoothie Works
Light, cold and hydrating
Cucumber is about 96 percent water, so a glass of this is mostly water with flavour, around 95 calories and more refreshing than most juices. The drink for a hot afternoon, after a workout, or before breakfast.
Creamy without dairy
A frozen banana gives the thick, foamy texture on the pin with no yogurt or milk. Vegan with maple instead of honey.
Five minutes, six ingredients
Chop, blend, pour. Nothing to soak or cook, and every ingredient is in an ordinary kitchen in summer.
Six ways from one base
Classic mint, tropical mango, green with spinach and ginger, spicy lime, berry and a yogurt-cream version, each a tab below.
Ingredients for a Cucumber Smoothie
English cucumber
One large, unpeeled and chopped, about 2 cups for two glasses. Long, thin-skinned, nearly seedless and never waxed. A garden or regular cucumber works peeled, with the seeds scraped out, or the smoothie turns bitter and watery.
Frozen banana
One ripe banana, peeled, chopped and frozen at least 4 hours. It thickens and sweetens; without it the smoothie is cucumber juice. Keep a bag of spotty bananas in the freezer.
Lime juice and zest
Two tablespoons of juice and a teaspoon of zest for two glasses. The acid is what makes cucumber taste bright instead of grassy. Lemon works the same way.
Fresh mint
Six to eight leaves, pinched to bruise them before they go in. Spearmint or peppermint, stems saved for tea. Without mint it is still good, just less cool-tasting.
Honey or maple
One to two teaspoons, less with a very ripe banana. Maple or agave for vegan. Taste before adding the second teaspoon.
Water or coconut water
Half a cup to loosen the blend. Coconut water adds a little natural sweetness and electrolytes and is the better choice after a workout; plain water keeps it neutral.
Salt
A pinch. It sharpens the cucumber and the lime the way it does in a salad.
Ice
Optional, a small handful for a slushier glass. The frozen banana and a chilled cucumber do most of the cooling.

English cucumber, unpeeled: thin skin, few seeds, no wax. A regular cucumber works peeled and seeded. Frozen banana is the creaminess; a fresh one makes a thin drink. Fresh lime only; bottled tastes flat. A pinch of salt is what makes cucumber taste like cucumber. Vegan with maple; halal as written.
Instructions
Chop the cucumber cold
Rinse the cucumber and chop it unpeeled into 1-inch chunks; the skin carries most of the colour and flavour. Chill it 30 minutes if there is time: cold cucumber makes a colder smoothie than ice does.
Load the blender
Water or coconut water first, then the frozen banana, then the cucumber. Add the lime juice and zest, the mint (pinched between your fingers to bruise it), the honey and the salt. Ice last if using.
Blend
Low for 10 seconds, then high for 45 to 60 seconds until completely smooth and pale green with a little foam on top. Stop and scrape once if cucumber bridges above the blades.
Taste and balance
Too tart, half a teaspoon more honey; too sweet, more lime; too thick, 2 tablespoons water; too thin, two ice cubes and a 10-second blend. The salt is already doing its work; do not skip it.
Pour and serve at once
Into chilled glasses with a cucumber coin on the rim, a mint sprig and a lime wedge. Drink within 10 minutes; the foam settles and the green dulls as it sits.
Four Rules for a Thick, Bright Cucumber Smoothie
In the jug: water, frozen banana chunks and cucumber going in, lime halves, mint and honey on the counter.
Frozen banana, cold cucumber
The banana makes it thick and the chilled cucumber makes it cold; ice alone makes it thin. Chop the cucumber the night before and keep it in the fridge.
Liquid at the bottom, low then high
Water first so the blades catch, 10 seconds on low, then high for a minute. Cucumber blends to foam; the foam is the sign it is done.
Bruise the mint, do not blend stems
Pinch the leaves to release the oil. Whole sprigs with stems turn the smoothie fibrous and faintly woody.
Salt and lime, then taste
A pinch of salt and fresh lime make the difference between a green drink and a cucumber smoothie. Taste before pouring and adjust by half a teaspoon at a time.

Six Ways to Make Smoothies with Cucumber
Up close: the foam on top, the pale green underneath, condensation on the glass.
Same base, a different glass. Tap a version:
Classic Cucumber Mint Smoothie
The recipe above: cucumber, frozen banana, lime, mint, honey, water. The two glasses on the pin.
Tropical Cucumber Mango Smoothie
Add 1 cup frozen mango and ½ cup pineapple to the classic, use coconut water in place of water, and a teaspoon of grated ginger. Keep or skip the mint. Sweeter, thicker and gold-green; the one for a pool day.
Green Cucumber Smoothie with Spinach and Ginger
Add 1 cup fresh spinach, 1 teaspoon grated ginger and 1 tablespoon chia seeds, and swap the lime for half a lemon. The spinach disappears into the green; the ginger is the warmth. A teaspoon of matcha if you want gentle caffeine.
Spicy Cucumber Lime Smoothie
Skip the mint, double the lime, add 1 or 2 thin slices of jalapeño with the seeds removed, and rim the glass with chili-lime salt. Cilantro instead of mint if you like it. Bold, sour and cold, and entirely alcohol-free as written.
Cucumber Berry Cooler
Add ½ cup frozen strawberries or raspberries to the classic and skip the honey; the berries sweeten it. Pale pink-green, a little tart. Blueberries turn it grey; stick to red berries.
Creamy Cucumber Yogurt Smoothie
Add ½ cup plain Greek yogurt and reduce the water to ¼ cup. Thicker, tangier, about 6 grams more protein a glass, and closer to a breakfast. A pinch of cumin instead of mint turns it toward a drinkable raita.

One of two glasses, with 1 teaspoon of honey. Sugar is from the banana and honey; about 3 g fibre. Vegan with maple; dairy-free except the yogurt version; halal and alcohol-free in every version.
Cucumber Smoothie: FAQs
How do you make a cucumber smoothie?
Blend one chopped unpeeled English cucumber with a frozen banana, the juice and zest of a lime, six to eight mint leaves, a teaspoon or two of honey, half a cup of cold water and a pinch of salt, low then high for about a minute. Two glasses in five minutes; the card above scales from one to six.
Do I peel the cucumber?
Not an English cucumber: the skin is thin, unwaxed and gives the smoothie its colour. Peel a regular cucumber and scrape out the seeds, or the smoothie turns bitter and watery.
Why is my cucumber smoothie bitter?
Three causes: a regular waxed cucumber with the skin on, the seeds, or the stem end, which carries the most bitter compounds. Use English cucumber, trim both ends, and add a squeeze more lime and a pinch of salt; both cut bitterness.
Is a cucumber smoothie healthy?
It is mostly water, with the fibre of a cucumber and a banana, a little natural sugar and about 95 calories a glass. It is a light, hydrating drink rather than a meal; the yogurt-cream version or a scoop of protein makes it breakfast.
Is it good for weight loss?
As a swap for a sweeter drink, yes: 95 calories, filling for its size and no added sugar beyond a teaspoon of honey. It is not a weight-loss drink on its own, and nothing here replaces a balanced meal.
Can I make it without banana?
Yes. Half an avocado or ½ cup frozen cauliflower rice gives the creaminess with less sweetness; ½ cup Greek yogurt gives it with tang. Add a teaspoon more honey since the banana was most of the sweetness.
Can I make it ahead?
Best within 10 minutes, but it keeps 24 hours in a jar filled to the top (shake it; it separates). Smoothie packs, cucumber chunks, banana and mint bagged in the freezer, blend in 30 seconds on a weekday morning.
What does it taste like?
Cool, lightly sweet and fresh, like a cucumber-lime drink with body. The banana is in the background; the mint and lime are what you taste first. Children usually like it because it is mild.
Can I add protein?
Yes. Half a cup of Greek yogurt adds about 6 grams; a scoop of unflavoured or vanilla protein adds 20 and needs a splash more water. Chocolate protein does not suit the cucumber.
What can I use instead of mint?
Basil for a sweeter herb note, cilantro for the spicy lime version, or nothing at all; the smoothie is still good. A pinch of cumin with yogurt turns it toward a drinkable raita.
Can I use coconut water?
Yes, in place of the plain water. It adds a little natural sweetness and electrolytes and is the better choice after a workout or on a hot day. The linked coconut water smoothies post builds eleven drinks on it.
Is it vegan and gluten-free?
Vegan with maple syrup or agave in place of honey; the yogurt version is the only one with dairy. Everything is naturally gluten-free. Halal as written, with nothing fermented or distilled in any version.
Can children drink it?
Yes; it is mild and pale green. Skip the mint if they object, halve the glass, and freeze leftovers in ice-pop moulds. The spicy lime version is for adults.
How many calories are in a cucumber smoothie?
About 95 per 12-ounce glass of the classic, from the banana and honey. The tropical mango version is closer to 180, the yogurt version about 140, and the berry cooler about 110.
