About Thai Watermelon Salad

Thai Watermelon Salad is a delightful balance of sweet, salty, tangy, and fresh herbs. Crisp cucumber and red onion contrast the juicy watermelon, while a simple lime- and ginger-forward dressing adds the Thai touch.

This salad is quick to prepare — under 10 minutes — and works well as a light meal or a colorful accompaniment to grilled dishes and soups.

It’s naturally gluten-free and can be made vegan by swapping fish sauce for soy sauce. Scale the recipe up for gatherings or serve it as a refreshing starter at summer parties.

Ingredients

Watermelon – Use ripe, seedless watermelon for the best flavor and texture.

Cucumber – English or Persian cucumbers work well because they are mild and often seedless. Peel if you prefer.

Onion – Thinly sliced red onion adds crunch and a touch of heat. If too strong, soak slices in cold water for 10 minutes and drain before using.

Peanuts – Toasted crushed peanuts give a crunchy finish. Substitute with cashews or almonds if desired.

Herbs – Fresh mint and Thai basil brighten the salad. If Thai basil is unavailable, regular basil is an acceptable alternative.

Dressing – A simple mix of lime juice, rice vinegar, fish sauce (or soy sauce for vegan), grated ginger, brown sugar, salt, and pepper ties everything together.

How To Make Thai Watermelon Salad

Step 1: Prepare the dressing. In a small bowl, whisk together:

  • 1 tablespoon lime juice
  • 1 tablespoon rice vinegar
  • ½ teaspoon fish sauce (or soy sauce for vegan)
  • ½ teaspoon grated ginger
  • 1 teaspoon brown sugar
  • ½ teaspoon salt
  • ¼ teaspoon freshly ground black pepper
Ready dressing.

Step 2: In a large bowl, combine:

  • 4 cups cubed seedless watermelon
  • ½ cup sliced cucumber
  • 2 tablespoons thinly sliced red onion
Watermelon, cucumber and onions mixed in a bowl.

Step 3: Pour the dressing over the fruit and vegetables and gently toss until everything is evenly coated.

Step 4: Top with 2 tablespoons crushed roasted peanuts, 2 tablespoons whole mint leaves, and 2 tablespoons whole Thai basil leaves. Serve immediately.

Storage Suggestions

This salad is best enjoyed right away. Watermelon and cucumber release water as they sit, which can make the salad watery over time. To save prep time, cut the watermelon, slice cucumbers, and slice onions in advance and store them separately in airtight containers in the refrigerator for up to 2 days. Toss with dressing and herbs just before serving.
