This mango cucumber salad mixes sweet, juicy mango with crisp cucumber and a tangy chili-lime dressing that wakes up everything on the plate. It comes together in minutes with zero cooking, so it’s the kind of thing you throw together when the weather is hot and you want something bold and refreshing.

It works as a side for grilled meat or fish, but honestly I eat it straight from the bowl.

Why This Salad Works

The dressing does all the heavy lifting here: bright lime, savory fish sauce, and a gentle heat that makes the fruit taste even sweeter. The mango turns creamy as you toss it, while the cucumber keeps a loud, watery crunch that stops the whole thing from feeling too soft.

I keep it in the rotation because it’s as good next to grilled chicken as it is tossed into a rice bowl for a quick lunch. No cooking, very little cleanup, and a flavor that feels much bigger than the effort.

Ingredients

1 large ripe mango: look for one that yields slightly when pressed but still feels firm enough to dice
1 English cucumber: no need to peel; its thin skin and crisp texture are ideal
1 small red chili: Thai bird’s eye for real heat, or a milder Fresno; remove seeds if you prefer less spice
handful fresh cilantro leaves: roughly torn
2 tbsp roasted peanuts: chopped, for crunch
2 tbsp fresh lime juice: about 1 lime
1 tbsp fish sauce: use a good-quality brand like Red Boat or Three Crabs
1 tsp brown sugar: light or dark; it balances the lime and salt

Variations / Substitutions

Add protein: toss in cold cooked shrimp or shredded chicken to turn it into a lunch salad
Veggie boost: thinly sliced red bell pepper or shredded carrot adds extra color and crunch
No fish sauce: use soy sauce or tamari for a vegan version; the flavor shifts but stays savory
Different herbs: Thai basil or mint work beautifully instead of cilantro
Milder heat: use a pinch of red pepper flakes or skip the chili and just crack fresh black pepper

If you like this combo, try Pineapple Cucumber Salad next—it swaps mango for juicy pineapple and uses the same lime-chili dressing.

How to Make Fresh Mango Cucumber Salad with Lime-Chili Dressing

Step 1: Slice the Mango and Cucumber

Peel the mango, slice the flesh off the pit, then cut it into ½-inch cubes. Halve the cucumber lengthwise, scoop out any large seeds if your cucumber has them, and slice into half-moons about ¼ inch thick. Aim for pieces that are roughly the same size so each bite gets a good mix of creamy and crisp.

Step 2: Whisk the Dressing

In a small bowl, combine the 2 tbsp lime juice, 1 tbsp fish sauce, and 1 tsp brown sugar. Whisk until the sugar dissolves completely. Taste and adjust: if your mango is very sweet you may not need more sugar; if the lime is sharp, add a tiny pinch more. Stir in the sliced chili right before you toss so it infuses the dressing without losing its brightness.

Step 3: Toss and Serve

Place the mango, cucumber, and torn cilantro in a large bowl. Pour the dressing over, scatter the chopped peanuts on top, and toss gently until everything is evenly coated. Spoon onto plates or a platter and serve right away. The peanuts soften quickly once dressed, so add them at the last minute for the best crunch.

Tips for the Best Mango Cucumber Salad

Use a mango that’s ripe but still firm—overly soft fruit will turn to mush when tossed.
If you want to make this ahead, keep the dressing, mango, cucumber, and peanuts in separate containers and toss right before eating. That way the cucumber stays snappy and the peanuts stay crisp.
A Y-shaped peeler makes fast work of mango skin if you peel a lot of fruit.
Don’t skip the peanuts. Their salty crunch cuts through the sweetness and gives the salad a satisfying finish.

Scale it for a crowd: adjust chili and sugar to taste.

Servings	Mango	Cucumber	Lime juice	Fish sauce
2	½ large	½ English	1 tbsp	½ tbsp
4	1 large	1 English	2 tbsp	1 tbsp
6	1½ large	1½ English	3 tbsp	1½ tbsp
8	2 large	2 English	4 tbsp	2 tbsp

Keeping Leftovers Fresh

Refrigerate: Leftover dressed salad can go into an airtight container and hold for up to 1 day, but the cucumber will release water and the peanuts will soften. Tossed fresh it’s at its best. If you kept the parts separate, they’ll stay good for 2 days in the fridge.

What Goes Well With This Salad

Spoon it next to grilled lemongrass chicken or seared salmon for a bright cool contrast against the heat of the protein. It also fits right into fish tacos or over a scoop of coconut rice—the tangy dressing cuts through rich dishes beautifully.

Frequently Asked Questions

Can I use frozen mango?

Yes, thaw it fully and drain off any liquid before dicing. Fresh mango gives a better texture, but frozen works in a pinch.

What if I don’t have fish sauce?

Soy sauce or tamari will work, though the flavor will be less deep. Start with half the amount and add more to taste.

How spicy is this salad?

With one small chili (seeds left in), the heat is mild but present. Remove the seeds for very little warmth, or switch to a pinch of red pepper flakes.

Can I make it vegan?

Absolutely. Swap the fish sauce for soy sauce or tamari and you have a fully plant-based version.
