On sweltering summer days, this refreshing Mexican Watermelon and Cucumber Salad is like a welcome splash of cool water. Crisp and sweet, with a punch of spicy pepper and tangy lime, this dish will have you clamoring for more. 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!
Ingredients
For the Smoky Lime Pepitas
- Raw pepitas (a.k.a. shelled pumpkin seeds)
- Extra virgin olive oil or avocado oil
- Diamond Crystal kosher salt
- Smoked paprika or ancho chili powder
- Cayenne pepper
- Juice from 1 medium lime
For the Mexican Watermelon and Cucumber Salad
- Thinly sliced red onions: White onions also work great!
- Seedless watermelon, cubed
- English or Japanese cucumber, cut into ½-inch slices
- Extra virgin olive oil
- Ancho chili powder
- Diamond Crystal kosher salt
- Cayenne pepper
- Fresh limes: You’ll be using both the zest and juice so step away from the bottled lime juice!
- Fresh mint leaves
How to make Mexican watermelon and cucumber salad
Let’s make the spiced pepitas first! Preheat the oven to 325°F with the rack placed in the middle position. In a medium bowl, combine the pepitas, olive oil, salt, paprika, cayenne, and lime juice. Mix well.
Spread the seasoned pepitas in a single layer on a parchment-lined rimmed baking sheet. Toast the seeds for 12 to 15 minutes in the oven, stirring at the halfway point, until fragrant and crunchy.
Cool to room temperature. Reserve ¼ cup for this recipe, and keep the rest in a sealed container for up to 1 week to munch on.
While the pepitas are in the oven, soak the onions in a bowl of ice water for about 10 minutes to take the bite off ’em.
In a large bowl, combine the watermelon, cucumber, drained onions…
…olive oil, chili powder, salt…
…cayenne pepper, lime zest, and lime juice. Toss to mix. Taste for seasoning, and adjust as necessary.
Garnish with fresh mint leaves and toasted pepitas.
Serve immediately!

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!
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!
This is so tasty and refreshing! I made it as a side for our Father’s Day bbq and it was a hit.
This is absolutely divine. All the foodies at the party demanded the recipe.
