Why Make This Lemonade? This is the most refreshing drink you will make all summer. Crisp, cool cucumber blends perfectly with tart, tangy lemonade to create a beverage that is light, hydrating, and utterly delicious. It is like sipping a spa treatment—clean, green, and just sweet enough. The cucumber adds a subtle vegetal freshness that balances the lemon’s brightness, while a hint of mint or basil takes it to the next level. Perfect for backyard barbecues, bridal showers, or simply cooling off on a hot afternoon.
Ingredients
For the cucumber lemonade: two medium English cucumbers (or four Persian cucumbers), one cup fresh lemon juice (about five to six large lemons), three quarters cup granulated sugar (or honey, simple syrup, or agave), four cups cold water (still or sparkling), and one cup ice cubes (plus more for serving). For garnish and extra flavor: fresh mint leaves, basil leaves, lemon slices, cucumber slices, edible flowers.
For the simple syrup (alternative to stirring sugar directly): one cup water, one cup granulated sugar (heat together until sugar dissolves, then cool).
Equipment Needed
A blender, a fine-mesh strainer or nut milk bag, a large pitcher, a citrus juicer (hand or electric), a sharp knife and cutting board, a wooden spoon or long spatula, a small saucepan if making simple syrup.
Method
Make the simple syrup (optional but recommended). In a small saucepan, combine one cup of water and one cup of granulated sugar. Heat over medium heat, stirring occasionally, until the sugar completely dissolves. Do not let it boil. Remove from heat and let it cool completely. Simple syrup mixes into cold drinks without leaving gritty sugar particles at the bottom of the pitcher. If you prefer to skip this step, you can stir granulated sugar directly into the lemonade, but it may take longer to dissolve.
Wash the cucumbers thoroughly. If using English cucumbers (the long, plastic-wrapped ones), you can leave the skin on—it is thin and tender. If using regular garden cucumbers, peel them if the skin is waxed or bitter. Cut the cucumbers into chunks.
In a blender, combine the cucumber chunks with one cup of cold water. Blend on high until completely smooth and frothy, about thirty to sixty seconds.
Pour the blended cucumber through a fine-mesh strainer or a nut milk bag into a large pitcher. Use a spatula to press the pulp against the strainer to extract as much juice as possible. You should get about one cup of clear cucumber juice. Discard the pulp.
Juice the lemons. Roll each lemon firmly on the counter under your palm to soften them before juicing. Cut them in half and juice using a citrus juicer. Remove any seeds. You will need one cup of fresh lemon juice, which takes about five to six large lemons.
In the pitcher with the cucumber juice, add the fresh lemon juice and the simple syrup (or three quarters cup of granulated sugar). Stir well to combine.
Add the remaining three cups of cold water and one cup of ice cubes. Stir again. Taste and adjust—add more simple syrup if you prefer a sweeter lemonade, more lemon juice for extra tartness, or more water if it is too strong.
Garnish with fresh cucumber slices, lemon wheels, and a sprig of mint or basil. Serve immediately over ice.
Storage
Refrigerate the lemonade in a sealed pitcher for up to three days. The cucumber flavor will fade slightly over time, and the lemonade may separate—just stir well before serving. Do not freeze, as the texture becomes icy and watery when thawed.
Variations
For sparkling cucumber lemonade, substitute the three cups of cold water with chilled sparkling water or club soda. Add the sparkling water just before serving to preserve the bubbles. For mint cucumber lemonade, add a handful of fresh mint leaves to the blender along with the cucumber. For basil cucumber lemonade, use fresh basil instead of mint. For ginger cucumber lemonade, add a one-inch piece of fresh peeled ginger to the blender with the cucumber. For strawberry cucumber lemonade, blend three or four fresh strawberries with the cucumber. For honey-sweetened version, replace the sugar or simple syrup with half a cup of honey (warmed slightly so it pours easily). For a low-sugar version, use one quarter cup of honey or agave, or a sugar-free sweetener like stevia or monk fruit to taste. For an adult version, add two to four ounces of vodka, gin, or white rum to the pitcher and stir.
Serving Suggestions
Serve at summer parties, bridal showers, or afternoon teas. Pair with grilled fish, chicken skewers, or light salads. Serve alongside cucumber sandwiches and scones for a garden party. Add a splash of gin or vodka for a sophisticated cocktail. Garnish with edible flowers like nasturtiums or violets. Freeze into popsicles for a healthy frozen treat. Serve in mason jars with striped paper straws for a rustic look.
Tips for Best Results
Use English cucumbers for the smoothest, least bitter juice. English cucumbers (also called hothouse or seedless cucumbers) have thin, tender skins and very small seeds. They do not need to be peeled. Regular garden cucumbers often have tough, waxy skins and large, bitter seeds. If using garden cucumbers, peel them and scrape out the seeds before blending.
Strain the cucumber juice well. Even high-powered blenders leave tiny bits of cucumber pulp that can make the lemonade cloudy and unpleasantly fibrous. A fine-mesh strainer or nut milk bag removes this pulp, leaving a clear, smooth juice. Pressing the pulp with a spatula extracts every drop.
Use fresh lemon juice, not bottled. Bottled lemon juice has a flat, bitter taste and lacks the bright, floral notes of fresh lemons. Freshly squeezed lemon juice is the soul of this drink. Roll the lemons on the counter before juicing to maximize juice yield.
Make simple syrup instead of stirring in granulated sugar. Simple syrup dissolves instantly and mixes evenly throughout the cold lemonade. Granulated sugar can sink to the bottom and leave a gritty texture. Simple syrup also allows you to sweeten the lemonade to taste gradually. It keeps in the refrigerator for up to two weeks.
Adjust sweetness and tartness to your preference. Start with three quarters cup of simple syrup and taste. If the lemonade is too tart, add more syrup. If it is too sweet, add more lemon juice. Everyone’s taste is different—this recipe is a starting point.
Add the ice to the pitcher, not just the glasses. Ice in the pitcher chills the lemonade evenly and slightly dilutes it to the perfect strength. If you prefer your lemonade less diluted, use chilled water and refrigerate the pitcher without ice, then serve over ice in individual glasses.
Garnish beautifully. A thin slice of cucumber floating in each glass, a sprig of mint, and a wheel of lemon make this lemonade look as good as it tastes. For extra flair, freeze cucumber slices or edible flowers into ice cubes.
Do not skip the resting time after blending. Letting the cucumber juice sit for a few minutes allows any remaining solids to settle, making straining easier. You can also strain the juice twice for an ultra-smooth result.
Make a double batch for parties. This lemonade is a crowd-pleaser. Double all ingredients and use a large beverage dispenser. Garnish with a whole cucumber cut into ribbons floating in the dispenser. Keep extra simple syrup and lemon juice on the side for guests to adjust to their taste.
Serve immediately for the brightest flavor. Cucumber lemonade is best enjoyed within a few hours of making it. The cucumber flavor is most vibrant right after blending. If you need to make it ahead, prepare the simple syrup, juice the lemons, and blend the cucumber separately. Combine everything just before serving.
