Jump to RecipeWatermelon Mint Cooler is a simple American-style summer drink made by blending ripe watermelon with fresh mint and lime, then finishing it with sparkling water. Its flavor is naturally sweet, cooling, and bright without needing much added sugar.
Straining the blended watermelon gives the drink a smoother, more polished texture, while adding the sparkling water at the end preserves its fizz. Use well-chilled watermelon and sparkling water so the cooler is ready to serve immediately; if your melon is not very sweet, add a little honey or agave to taste.
Ingredients
- 4 cups (600 g) seedless watermelon, cubed and chilled
- 1/4 cup (10 g) fresh mint leaves, plus more for garnish
- 2 tbsp (30 ml) fresh lime juice
- 2 tbsp (30 ml) honey or agave syrup, optional
- 1 cup (240 ml) chilled sparkling water
- 2 cups (280 g) ice cubes
Instructions
- 1
Add the chilled watermelon, mint, lime juice, and honey or agave, if using, to a blender. Blend on high until completely smooth, about 30-45 seconds.
- 2
Set a fine-mesh sieve over a pitcher and pour in the watermelon mixture. Press gently with a spoon to extract the liquid, then discard the remaining pulp.
- 3
Taste the strained cooler. Stir in more lime juice for brightness or a little more sweetener if the watermelon is bland.
- 4
Pour in the chilled sparkling water and stir gently once or twice so it stays fizzy.
- 5
Divide the ice among four glasses and pour the cooler over it.
- 6
Garnish with mint leaves and serve immediately.
Tips for the Best Watermelon Mint Cooler
- Choose a ripe, seedless watermelon that feels heavy for its size and smells sweet at the stem end; an underripe melon will make a flat-tasting cooler.
- Chill the watermelon and sparkling water before blending so the drink does not need extra chilling and the carbonation lasts longer.
- Do not overblend after adding sparkling water, or the drink will lose its fizz.
- For a pulpier drink, skip straining. For a smoother drink, strain twice through a clean fine-mesh sieve.
- Make the watermelon-mint base up to 1 day ahead and refrigerate it in a covered pitcher. Add sparkling water and ice just before serving.
- Agave keeps the drink vegan; honey adds a fuller floral flavor but is not vegan.
Storage and Reheating
Refrigerate the strained watermelon base in a covered container for up to 24 hours. Store it without sparkling water or ice, then stir in fresh sparkling water when serving. The finished cooler is best served immediately and should not be frozen after carbonation is added.
Frequently Asked Questions
Can I make watermelon mint cooler without sparkling water?
Yes. Replace the sparkling water with the same amount of cold still water, or use coconut water for a slightly sweeter drink. It will be refreshing but not fizzy.
Can I make watermelon cooler ahead of time?
Prepare and refrigerate the strained watermelon base for up to 24 hours. Add the sparkling water, ice, and garnishes immediately before serving.
How do I make watermelon mint cooler sweeter?
Add honey or agave syrup a little at a time while blending. The amount needed depends on the ripeness of the watermelon.
Can I use frozen watermelon?
Yes, but let it soften slightly before blending. You can reduce the ice because frozen watermelon will chill and thicken the drink.
