Instructions

  1. 1

    Prep the watermelon. Cut the watermelon into bite-sized cubes and spread them on a paper towel-lined sheet pan for about five minutes. This pulls off excess juice so the salad doesn't turn into soup at the bottom of the bowl.

  2. 2

    Slice the cucumber and onion. Cut the cucumber into thin half-moons and the red onion into paper-thin slices. If the raw onion tastes too sharp, soak the slices in ice water for five minutes, then drain and pat dry.

  3. 3

    Toss the salad together. Add the watermelon, cucumber, and red onion to a wide, shallow bowl or platter. Scatter the crumbled feta and torn mint over the top. A flat platter works better than a deep bowl here — you want to see every layer instead of burying the feta underneath.

  4. 4

    Dress it. Drizzle the olive oil and lime juice directly over the salad. Finish with a pinch of flaky salt and a few cracks of black pepper. Gently toss once or twice — just enough to combine without breaking up the watermelon cubes.

  5. 5

    Serve right away. This salad is best within about 30 minutes of assembly. The watermelon will start releasing liquid as it sits, so dress it just before serving for the cleanest presentation.

Watermelon feta salad combines cold watermelon cubes, salty feta, torn mint, cucumber and thin red onion with a simple olive oil and lime dressing. It serves 6 and takes about 20 minutes with no cooking. The one trick that matters is draining the watermelon and dressing the salad at the last minute so it does not turn watery.

Ingredients

Salad

  • 6 cups seedless watermelon, cut into roughly 1-inch cubes (about a quarter of a large melon)
  • 4 oz feta cheese, crumbled into chunky pieces — block feta from the deli section holds up better than pre-crumbled
  • 1/3 cup fresh mint leaves, torn or thinly sliced
  • 1 small English cucumber, halved lengthwise and sliced into half-moons
  • 1/4 cup thinly sliced red onion (about half a small onion)

Dressing

  • 3 tablespoons good olive oil
  • 1 tablespoon fresh lime juice (lemon works too)
  • Flaky salt and black pepper to taste

Draining, Layering and Dressing the Salad

  1. Prep the watermelon. Cut the watermelon into bite-sized cubes and spread them on a paper towel-lined sheet pan for about five minutes. This pulls off excess juice so the salad doesn’t turn into soup at the bottom of the bowl.

  2. Slice the cucumber and onion. Cut the cucumber into thin half-moons and the red onion into paper-thin slices. If the raw onion tastes too sharp, soak the slices in ice water for five minutes, then drain and pat dry.

  3. Toss the salad together. Add the watermelon, cucumber, and red onion to a wide, shallow bowl or platter. Scatter the crumbled feta and torn mint over the top. A flat platter works better than a deep bowl here — you want to see every layer instead of burying the feta underneath.

  4. Dress it. Drizzle the olive oil and lime juice directly over the salad. Finish with a pinch of flaky salt and a few cracks of black pepper. Gently toss once or twice — just enough to combine without breaking up the watermelon cubes.

  5. Serve right away. This salad is best within about 30 minutes of assembly. The watermelon will start releasing liquid as it sits, so dress it just before serving for the cleanest presentation.

Why Watermelon Salad Gets Watery

The most common cause is dressing it too early. Salt draws moisture out of cut watermelon quickly, so add salt at the very last moment. Blotting the cubes with a paper towel, as in the first step, helps too, and a ripe but firm melon holds up better than an overripe one.

Feta, Mint and Add-In Swaps

  • Instead of feta: Fresh goat cheese, ricotta salata or cotija all give the salty, creamy contrast the sweet melon needs.
  • Instead of mint: Basil is the closest swap and brings a different herbal note. Cilantro works if you like it.
  • Extras: Arugula or baby spinach underneath adds a peppery base; olives, toasted pistachios or a drizzle of balsamic glaze also pair well. Keep to one or two so the watermelon and feta stay in front.

What to Serve With Watermelon Feta Salad

This salad belongs next to anything coming off the grill, such as marinated grilled steak, garlic butter shrimp skewers or smash burgers. For an all-salad summer table, add the grilled peach salad with burrata. It also works as a light lunch with crusty bread and hummus.

Making It Ahead

You can cube the watermelon, slice the vegetables and crumble the feta a few hours ahead. Store them in separate containers in the fridge and combine and dress the salad right before serving. Cut watermelon should not sit at room temperature for long; in hot weather (above 90°F) keep it chilled and do not leave it out for more than 1 hour.

FAQ

Can I make this salad ahead?

Prepare the components ahead, but assemble and dress just before serving; the watermelon releases liquid once cut and dressed.
