This is what happens to the extra watermelon nobody finishes at a cookout. Instead of letting it go soft in the fridge, it gets blended with mint and lime into something that disappears faster than the fruit did on its own.

Ingredients You’ll Need
| Ingredient | Quantity | Notes & Substitutions |
|---|---|---|
| Watermelon, cubed and seeded | 4 cups | The riper the better, for natural sweetness |
| Fresh mint leaves | 10 to 12 | Plus more for garnish |
| Lime juice | 2 tbsp | Fresh only |
| Honey or simple syrup | 1 to 2 tbsp | Adjust depending on how sweet the watermelon is |
| Sparkling water | 1 cup | Adds fizz at the end |
| Ice | As needed |
Pro tip: taste the watermelon before deciding how much sweetener to add. A very ripe melon might not need any at all.
Kitchen Tools & Equipment
- A blender
- A fine mesh strainer, optional, for a smoother texture
Step by Step Instructions
Step 1: Prep the Ingredients
Cube and seed the watermelon if it isn’t already prepped, using the grid method to make quick work of it.
Step 2: Blend
Combine watermelon, mint, lime juice, and sweetener in a blender. Blend until smooth.
Step 3: Strain
Strain through a fine mesh strainer if you prefer a smoother texture, or leave it as is for a more rustic drink.

Pour over ice in glasses, filling about three quarters full.
Step 5: Serve and Enjoy!
Top each glass with sparkling water and a sprig of fresh mint.
Expert Tips & Common Mistakes to Avoid
Tips:
- Chill the watermelon before blending so the finished drink is cold without needing to water it down with extra ice.
- Add the sparkling water right before serving, not during blending, so it keeps its fizz.
Mistakes:
- Blending in the sparkling water, which flattens it immediately and leaves the drink less refreshing.
- Oversweetening before tasting the watermelon first, since ripeness varies a lot from melon to melon.
Recipe Variations & Customizations
- Add a splash of white rum or vodka for an adult version.
- Swap mint for basil for a slightly different herbal note.
- Make it a slushy by blending with ice instead of serving over it.
What to Serve With This Dish
This is a natural pairing with anything from the grill, and works especially well alongside grilled corn on the cob or smashburgers at a summer cookout.
How to Store & Reheat Leftovers
Storage: store the blended watermelon mixture, without the sparkling water, in the fridge for up to 2 days.
Reheating: not applicable, this is served cold.
Freezing: freeze the blended mixture into ice cubes for a fun way to keep drinks cold without watering them down.
FAQs About This Recipe
Can I make this ahead of time?
Yes, blend the watermelon mixture ahead and refrigerate, then add sparkling water and ice just before serving.
Can I make this without a blender?
A food processor works as a substitute, though you may need to strain more thoroughly since it can leave more pulp.
Final Thoughts
This drink has quietly become the reason I buy a second watermelon at the store, just so there’s extra for blending.
Save this one for the next time a watermelon is about to go to waste.
