Summer Watermelon and Arugula Salad with Feta Recipe

Watermelon and Arugula Salad combines sweet, juicy watermelon with peppery arugula and creamy feta. A bright lime and Champagne-vinegar vinaigrette, gently spiced with jalapeño and rounded with olive oil, ties everything together for a refreshing summer salad you’ll want to serve often.

I used to think watermelon was little more than sweet, diluted sugar water. Kids at summer barbecues would devour dripping wedges while I passed. Over time my taste changed: paired with bold, contrasting flavors, watermelon’s cool sweetness becomes the perfect foundation for a memorable salad. Combined with peppery greens, tangy cheese and a lively vinaigrette, watermelon finally found its place on my plate.

A nod to the growers who produce flavorful melons: when watermelon is ripe and well grown, it brings a clean sweetness that plays beautifully against savory and acidic elements. This salad is one of those simple summer recipes that feels special but comes together quickly.

Watermelon & Arugula Salad Ingredients

• Watermelon: Choose a small seedless watermelon that feels heavy for its size; half of a 5–6 pound melon is ideal for this recipe.
• Arugula: Baby arugula has a tender bite and mild pepperiness; mature arugula can be tougher and spicier.
• Feta: A firm block is easy to cut into small cubes; crumbled feta works too if you prefer a more distributed salty bite.
• Lime juice: Freshly squeezed is best—about the juice of one lime (approximately 2 tablespoons).
• Champagne or white wine vinegar: Adds bright acidity without overpowering the fruit.
• Shallot: Finely chopped shallot gives a delicate onion flavor; red onion will be stronger if substituted.
• Jalapeño: Use half a jalapeño for gentle heat, or the whole pepper if you want more spice. Remove seeds for milder flavor.
• Fresh thyme: The leaves add a subtle herbal note; dried thyme may be substituted at roughly half the amount.
• Olive oil: A good-quality extra-virgin olive oil yields the best mouthfeel in the vinaigrette.
• Kosher salt and black pepper: For seasoning the dressing and the finished salad.

How to Make Watermelon & Arugula Salad

Make the vinaigrette first: combine fresh lime juice, Champagne or white wine vinegar, finely chopped shallot, jalapeño and thyme in a blender or small food processor and blend until smooth. With the blender running, stream in the olive oil until the dressing is emulsified. Season with kosher salt and freshly ground black pepper to taste.

Arrange cubed watermelon, arugula and feta on a serving platter or divide among plates. Drizzle the vinaigrette just before serving so the arugula stays crisp. Taste and finish with a sprinkle of kosher salt and freshly ground black pepper.

Recipe Variations

• Thinly sliced red onion adds a sharper bite and a little extra heat.
• Swap feta for goat cheese or shaved Parmesan for a different creamy note.
• Toss in fresh mint leaves with the arugula for additional herbal brightness.
• Make it a main course by adding grilled shrimp or sliced grilled chicken for protein.

Make Ahead and Storage

The vinaigrette can be made and refrigerated up to three days in advance; shake or whisk it before using if it separates. Cube watermelon a day ahead and store in an airtight container in the refrigerator. Keep the arugula separate and dress the salad just before serving to prevent wilting.
