Besides, it pairs well with just about anything you throw on the barbecue this grilling season!

My Mexican Watermelon Salad recipe comes from our new cookbook, Ready or Not!, and it’s one of my favorite hot weather side dishes. You won’t heat up the kitchen by making this tasty crowd pleaser—a win-win in my book.

Not a fan of Mexican flavor?

Just leave out the ancho chili powder and use more cayenne (to make it spicier) or smoked paprika (to make it smokier). The combination of watermelon, zingy lime juice, fresh herbs, and crunchy and smoky pepitas is truly magical.

Make-Ahead Tips

Pro tip: If you’re making this salad ahead of time, don’t add the olive oil, herbs, and pepitas until you’re ready to eat—otherwise, the olive oil can solidify in the fridge and the pepitas can get soft. Also, this recipe calls for toasting more pepitas than necessary for this dish, but you’ll thank me later when you have leftover crunchy smoky salad toppers on hand for the rest of the week!

    Packed full of flavor! I just made this salad, and it was so refreshing, with a nice heat from the spiced pepitas! Should have made sure I bought a SEEDLESS watermelon–oops. But the flavors were terrific!

  2. Found this recipe several summers ago and make it all summer. As soon as the bowl is empty I make more! Don’t forget the.mint, it just makes it so good!

    So stinking good! I added a few things we had in ours in Cabo. 1/4 cup of corn and about 8 cherry tomatoes cut. So yummy!
