This Watermelon Feta Salad is a refreshing summer side dish made with ripe & juicy watermelon, feta cheese, & fresh mint for the perfect balance of sweet, salty, & herbaceous. It comes together in just 10 minutes with no cooking, making it ideal for BBQs, picnics, and warm-weather gatherings!
Refrigerate the watermelon for at least 2 hours to keep it firm, then cut it into ½-inch cubes (about 6 cups). Thinly slice the red onion and chop the mint. Remove the feta from the brine (reserve 1 teaspoon of brine), pat dry, and crumble into bite-sized chunks. In a small bowl, whisk together the juice of 1 lemon, 2 cloves of minced garlic, the reserved feta brine, flaky sea salt, and freshly cracked black pepper; the brine adds lactic acid and helps the dressing cling to the watermelon.
Add the watermelon, chopped red onion, chopped mint, and ½ cup of crumbled feta to a large bowl. Pour the dressing over top and gently toss, avoiding vigorous mixing to keep the watermelon intact. Scatter the other ½ cup of crumbled feta on top just before serving to preserve texture, and serve immediately, or refrigerate up to 30 minutes if needed.
Notes
Best Temperature For Serving: This watermelon mint salad is best served chilled (around 50-55°F) rather than ice-cold. This preserves the crunch and highlights the mint's floral notes; I always remove it from the fridge 10 minutes before serving.
Flaky Salt Is Best: Large-flake sea salt like Maldon or fleur de sel maintains the watermelon's structure longer than fine table salt, keeping the salad crisp for over an hour.
Sheep's Milk Feta Wins: Higher-fat feta (6-8% in sheep's milk vs. 4-5% in cow's milk) stays creamy and moist.
Cube Size Matters: Cut the watermelon into ½-inch cubes to reduce moisture release and ensure each bite has a perfect balance of fruit, feta, and mint.
