A Summer Favorite From Meryl Fury
This watermelon cucumber lime salad is the dish I make on repeat all summer long. When it's hot out and only something cold and crisp sounds good, this is what I reach for. Watermelon and cucumber hit their peak at the same time, a generous squeeze of lime wakes everything up, and a little salt or Tajín ties the sweet and tart flavors together.
It barely needs a recipe. Cube whatever watermelon looks best, chop some cucumber for crunch, then squeeze in lime and taste until it's right: a little salty, a little sour, a little sweet. It also travels well, which makes it my go-to for picnics and potlucks.
Watermelon, Cucumber & Lime Salad
You only need four ingredients. Here's what to look for:
Watermelon
Ripe, in-season and seeded. It's the star, so pick a heavy melon with a creamy yellow field spot.
Cucumber
Scrub the skin well and leave it on for color and crunch.
Limes
At least three. Fresh juice makes the fruit taste brighter.
Salt or Tajín
A pinch of either one, or both, to balance the sweetness.

How to Make Watermelon Cucumber Salad
Here's how to make it in 4 easy steps:
Cube the watermelon. Cut the seeded watermelon into bite-size cubes and add them to a large bowl.
Prep the cucumber. Quarter it lengthwise, then slice it into bite-size pieces so they match the watermelon.
Squeeze in the lime. Juice the limes right over the bowl. Start with three and add more as you taste.
Season and chill. Add a pinch of salt or Tajín, toss gently, and keep it cold until you serve.
Taste, adjust, and enjoy!
Recipe Variations
For a little heat, use Tajín in place of the salt, or use both. Start light and build up.
To drink it instead, put the same watermelon, cucumber and lime in a blender and blend until smooth for a rosy-pink summer drink. Season it to taste just like the salad.
For a crowd, scale everything up and keep roughly the same ratio of 2 parts watermelon to 1 part cucumber.
What to Serve with Watermelon Cucumber Salad
This salad is built for warm-weather gatherings. There are no leafy greens to wilt, so it holds its texture in a cooler and is a natural fit for picnics, potlucks and backyard cookouts. Serve it alongside your favorite plant-based mains and sides, and give it one more squeeze of lime or sprinkle of Tajín right before eating.
Storage Tips
Keep the salad chilled until you're ready to serve. It's best the day it's made, since the watermelon releases juice as it sits. Store leftovers covered in the refrigerator and drain off extra liquid before serving.
