FAQs
Use a sharp knife to slice off both ends of the watermelon. Stand it upright, carefully slice off the green rind, and cut the flesh into slices. To finish, cut the flesh into bite-sized cubes. For another easy method, check out this helpful video.
From chilled tomato gazpacho to fluffy tomato bread to stuffed tomatoes, there’s so much you can do with an abundance of fresh summer tomatoes.
No, I don’t recommend making the salad ahead of time because it will become watery and less flavorful as it sits. If you do want to get a jump on the recipe, assemble the dressing in a sealed jar a few days before pouring it over the salad.
Pro Recipe Tips
- Always salt the tomatoes: This helps their natural juices drain and makes the salad less watery. While you’re at it, salt the cucumbers, too! Afterward, just give them a rinse under running water and pat them dry.
- Marinate the cucumbers: Toss the sliced cucumbers in the dressing for 1 to 2 minutes while the tomatoes are being salted. The marinade will slightly soften their crunch and fill them with flavor.
- Don’t skip the chill: Once it’s assembled, pop the watermelon salad in the fridge for at least 30 minutes so all of those bold and vibrant flavors can get to know each other.
Serving Recommendations
- Enjoy it as a light and healthy lunch or appetizer.
- Serve it on the side of your favorite summer main dishes, like slow cooker jackfruit carnitas, couscous salad with fresh vegetables, roasted veggie tacos, or spicy red bean burgers.
- With even more refreshing summer salads, like this easy edamame salad, French potato salad, or Southwest quinoa salad.
- Enjoy it on the side of a fresh summer pasta, like sun dried tomato pasta salad, this amazing avocado pesto pasta, or Mediterranean vegan pasta salad.
Storage Instructions
The assembled watermelon and tomato salad is best eaten the day it’s made. If it sits for too long, the watermelon and tomatoes will start to release their natural juices, making the salad soggy. However, if you end up with leftovers, they can be stored in an airtight container in the fridge for up to 3 days.
