Prep Time: 15 minutes
Chill Time: 1 hour (minimum)
Total Time: 1 hour 15 minutes

Intensity Levels

To help you plan your kitchen workflow, here’s a breakdown of the intensity for each step of the recipe.

Prep Intensity: Medium
- Peeling, seeding, and chopping the cucumber requires a bit of knife work, but it’s straightforward. Juicing the lemons can be a workout if you don’t have a press.
Blending Intensity: Low
- The food processor or blender does all the heavy lifting here.
Straining Intensity: Medium
- Straining the cucumber puree requires some patience and elbow grease to extract all the juice and discard the pulp.
Flavor Intensity: Balanced & Refreshing
- This recipe creates a flavor profile that is not too sweet, not too tart, with a distinct and cooling cucumber finish.
Difficulty Level: Easy
- The steps are simple and foolproof. The key is adjusting the sweetness to your personal taste.

3/4 to 1 cup granulated sugar, or simple syrup to taste
4 cups cold water

Ice cubes
Fresh mint sprigs
Thin cucumber slices or ribbons

Fine-mesh strainer or nut milk bag
Large pitcher (2-quart capacity)
Wooden spoon or spatula

Step-by-Step Instructions

1. Prepare the Cucumber Puree

Wash the cucumber thoroughly. Peel the skin off using a vegetable peeler. The skin can add a slightly bitter taste to the puree, so removing it ensures a clean, sweet flavor.
Cut the cucumber in half lengthwise. Use a spoon to scoop out the seeds. The seeds have a high water content but can also contribute a touch of bitterness. For a super smooth and pure flavor, remove them.
Roughly chop the peeled and seeded cucumber into 1-inch chunks.
Place the chopped cucumber and the 1/2 cup of water into your food processor or blender. Purée until completely smooth and liquid, which should take about 1-2 minutes.

2. Strain the Puree

This is a crucial step for a smooth lemonade. Set your fine-mesh strainer over a large bowl or directly over your pitcher. Line the strainer with a cheesecloth or nut milk bag if you have it, but a fine-mesh strainer alone works well.
Pour the cucumber puree into the strainer.
Use a spatula or the back of a spoon to press the puree against the strainer, extracting as much liquid as possible. You should get about 1 to 1.5 cups of vibrant green cucumber juice.
Discard the dry pulp left in the strainer.

3. Make the Simple Syrup (Optional but Recommended)

While you can stir sugar directly into cold lemonade, it dissolves much better in a simple syrup.
In a small saucepan, combine 1 cup of sugar and 1 cup of water (this is not the water from the ingredients list; it’s separate).
Heat over medium heat, stirring frequently, until the sugar is completely dissolved. Do not let it boil. Remove from heat and let it cool. This is your simple syrup.

4. Juice the Lemons

Roll the lemons on the countertop under your palm to break down some of the internal membranes, making them easier to juice.
Cut the lemons in half and juice them using a juicer or reamer. Make sure to remove any seeds.
Measure out 1 cup of fresh lemon juice. Freshly squeezed is non-negotiable for the best flavor; bottled juice will taste flat in comparison.

5. Combine and Sweeten

In a large pitcher, combine the cucumber juice, the fresh lemon juice, and your simple syrup (or granulated sugar).
Start with 3/4 cup of sugar or the equivalent amount of simple syrup. Stir well.
Add the 4 cups of cold water. Stir again to combine all the ingredients.

6. Taste and Adjust

This is the most important step. The sweetness of cucumbers and lemons can vary.
Take a sip and adjust to your liking. Add more lemon juice for extra tartness or more simple syrup for additional sweetness.
The flavor will mellow and meld as it chills, so it’s okay if it’s slightly more intense at this stage.

7. Chill and Serve

Place the pitcher in the refrigerator to chill for at least one hour. This allows the flavors to marry beautifully.
To serve, fill glasses with ice. Pour the chilled cucumber lemonade over the ice.
Garnish with a thin slice of cucumber, a lemon wheel, and a sprig of fresh mint for a beautiful and aromatic finish.

Chef’s Notes & Variations

For a “Cucumber Cooler” (Mocktail): Muddle a few fresh mint leaves with a teaspoon of sugar in the bottom of a glass before adding ice and the lemonade.
Cucumber-Lime Mint Lemonade: Substitute half of the lemon juice with fresh lime juice and add a handful of fresh mint leaves to the pitcher while chilling.
Spicy Kick: Add a slice of jalapeño to the pitcher for a subtle heat that pairs surprisingly well with the cool cucumber.
Make it a Cocktail: This lemonade is a perfect mixer! Add a shot of gin, vodka, or white rum for a sophisticated summer cocktail.
Storage: This lemonade is best enjoyed fresh on the day it’s made. However, it can be stored in a sealed pitcher in the refrigerator for up to 2 days. The cucumber flavor may fade slightly, but it will still be delicious. Just give it a good stir before serving, as some separation is natural.
