Why You’ll Love This Recipe
This watermelon cucumber salad solves the biggest summer cooking challenge – creating something fresh and satisfying without turning on the oven. Last month I served this at a backyard barbecue and watched guests go back for thirds, asking for the recipe before they even finished eating. The beauty lies in its versatility – you can dress it up with feta cheese for dinner parties or keep it simple for everyday meals. The combination works because watermelon’s sweetness perfectly balances cucumber’s mild freshness, while herbs add aromatic depth that elevates the entire dish. Plus it’s naturally gluten-free, vegan-friendly, and requires zero cooking skills.
Ingredients You’ll Need
Main Ingredients
- 4 cups cubed watermelon – Choose watermelon that sounds hollow when tapped and feels heavy for its size. The flesh should be deep red with black seeds (or seedless varieties work too). You can substitute cantaloupe if watermelon isn’t available.
- 2 large English cucumbers – English cucumbers have thinner skins and fewer seeds than regular cucumbers, making them perfect for this salad. Regular cucumbers work but peel them first and remove seeds if they’re large.
- 1/2 red onion, thinly sliced – Red onion adds sharpness that cuts through the sweetness. Soak slices in cold water for 10 minutes to mellow the bite if you prefer milder flavor.
Fresh Herbs & Flavor Boosters
- 1/4 cup fresh mint leaves – Mint brightens everything and adds cooling properties. Fresh basil makes an excellent substitute if mint isn’t your thing.
- 2 tablespoons fresh lime juice – Fresh lime juice is crucial – bottled just won’t give the same bright acidity. Lemon juice works as backup.
- 1 tablespoon olive oil – Use good quality extra virgin olive oil for best flavor. Avocado oil is another healthy option.
- Salt and pepper to taste – Sea salt or kosher salt work best. Freshly cracked black pepper adds more complexity than pre-ground.
How to Make Watermelon Cucumber Salad
Step 1: Cut watermelon into 1-inch cubes, removing seeds as you go. Place in large mixing bowl and pat dry with paper towels to remove excess moisture.
Step 2: Slice cucumbers into half-moons about 1/4 inch thick. Add to bowl with watermelon. The contrasting shapes create visual appeal and help ingredients mix evenly.
Step 3: Slice red onion paper-thin using sharp knife or mandoline. Soak in cold water for 5-10 minutes if you want milder onion flavor, then drain and pat dry.
Step 4: Tear mint leaves by hand rather than chopping with knife – this prevents bruising and keeps herbs fresh longer. Add torn mint and onion slices to watermelon mixture.
Step 5: Whisk lime juice, olive oil, salt and pepper in small bowl. Taste and adjust – you want bright acidity that enhances but doesn’t overpower the fruit.
Step 6: Pour dressing over salad and toss gently with large spoon. Let sit 10-15 minutes before serving to allow flavors to blend together.
