The watermelon salad is super-easy to make, with just a few key ingredients. Take the additional step of making your own pickled red onions the night before and you will be a watermelon salad superstar at the next BBQ, I promise!
I shared two ways you could serve it in the photos below, either of which will wow your guests. Me, I’d prefer a giant bowl, a spoon, and a napkin for the balsamic reduction that I’ll probably drip on my shirt. (Balsamic reduction is like balsamic vinegar, which you can use as well, but thicker like a drizzle. If you only have vinegar, you can certainly use that too. But once you buy balsamic reduction you can be all, “Oh, I use this ALL the time, because I’m fancy like that.”)
Watermelon Salad
Since you can make this salad in single serving dishes or as a large bowl, there are no suggested measurements, just an outline of what you’ll need!
Ingredients
- Cubed watermelon
- Crumbled feta cheese
- Baby or tender arugula
- Pickled Red Onions (see recipe below)
- Balsamic reduction
Instructions
- Arrange the arugula in your bowl or serving platter.
- Top with cubed watermelon, then feta, then pickled red onions
- Drizzle with balsamic reduction and serve

Pickled Red Onions
Today’s recipe calls for Pickled Red Onions, but if you make a batch now, save them for topping other salads, sandwiches, burgers, tacos, nachos and more.
Ingredients
- 1 medium red onion, thinly sliced (you can either slice them as a big round circle or in strips)
- ½ cup apple cider vinegar OR white wine vinegar (NOT white vinegar)
- 1 cup warm water
- 1 teaspoon sugar
- 1 teaspoon pickling or Kosher salt (I use sea salt if that’s all I have on hand)
Instructions
- Place onion in a mason jar or glass bowl.
- Combine the vinegar, water, sugar and salt in a mixing bowl or large measuring cup and mix together until the sugar and salt is dissolved.
- Pour liquid over onions, cover and refrigerate. You’re done!
- Refrigerate 24 hours for best flavor though you can keep the onions for weeks in your fridge and the flavor keeps getting better!

Enjoy!
