Light, crunchy, and bursting with color, this Thai mango cucumber salad will become your go-to summer salad.

Why This Thai Mango Cucumber Salad Works

The magic of this salad is the dressing. Traditional Thai dressing balances four core flavors: palm sugar for sweetness, lime juice for sour, fish sauce for salty, and fresh chilies for spicy. This recipe uses honey as an accessible substitute for palm sugar. The dressing is not emulsified. It sits at the bottom of the bowl until tossed, which means every bite gets a fresh burst of bright, bold flavor. Using firm, unripe mangoes is essential. Ripe mangoes are too soft and sweet. Unripe mangoes hold their shape and provide a tart, crisp contrast to the cool cucumber. English cucumbers have fewer seeds and thinner skins than regular cucumbers, making them ideal for this salad.

Ingredients

For the Salad:

2 firm, unripe mangoes, julienned or thinly sliced
1 English cucumber, julienned or thinly sliced
1/4 cup fresh cilantro, roughly chopped
1/4 cup fresh mint leaves, roughly chopped
1/4 cup red onion, thinly sliced
1/4 cup roasted peanuts, crushed (optional)

For the Thai Dressing:

3 tablespoons fresh lime juice (about 2 limes)
2 tablespoons fish sauce
1 tablespoon honey or palm sugar
1 clove garlic, minced
1 small Thai bird’s eye chili or serrano pepper, thinly sliced (adjust to taste)

Step-by-Step Instructions

Step 1: Prepare the Produce

Peel the mangoes. Slice the flesh away from the pit. Cut into thin matchsticks or julienne strips. For the cucumber, slice off the ends. Cut in half lengthwise. Scoop out the seeds with a spoon if desired. Slice into thin half-moons or julienne strips. Thinly slice the red onion. Roughly chop the cilantro and mint.

Step 2: Make the Dressing

In a small bowl or jar, whisk together the lime juice, fish sauce, honey, minced garlic, and sliced chili. Whisk until the honey dissolves completely. Taste and adjust. Add more fish sauce for saltiness, more lime for sourness, or more honey for sweetness.

Step 3: Combine the Salad

In a large bowl, combine the julienned mango, cucumber, red onion, cilantro, and mint. Toss gently to mix.

Step 4: Dress and Toss

Pour the dressing over the salad just before serving. Toss well to coat every piece. Do not dress too far in advance, as the acid will soften the mango and cucumber.

Step 5: Garnish and Serve

Transfer the salad to a serving bowl or platter. Sprinkle with crushed roasted peanuts if using. Serve immediately. This salad is best eaten fresh.

Variations and Tips

Add shredded carrots or bell peppers for extra color and crunch. Substitute green apples for mango for a different sweet-tart flavor. Use coconut aminos instead of fish sauce for a vegan version. Add cooked shrimp or shredded chicken to make it a main dish salad. Add a teaspoon of sesame oil to the dressing for nuttiness. Substitute basil for mint. This salad does not store well, as the dressing softens the vegetables. Make the components ahead and dress just before serving. The dressing keeps in the refrigerator for up to one week. For a milder salad, remove the chili seeds or omit the chili entirely. For a spicier salad, add an extra chili or a dash of sriracha. Serve alongside Thai coconut curry, grilled satay, or lemongrass chicken. This Thai mango cucumber salad is also excellent as a filling for summer rolls or as a topping for tacos and rice bowls. The combination of sweet, sour, salty, spicy, and fresh herbal notes makes every bite exciting. It is light enough for a hot summer day but flavorful enough to stand up to rich, heavy dishes. Make a double batch for parties, as this salad disappears quickly. It is naturally gluten-free dairy-free and can easily be made vegan. The bright colors and bold flavors will make this Thai mango cucumber salad your most-requested recipe.
