This fresh watermelon salsa recipe is a festive mixture of juicy watermelon, savory red onion, and fiery hot peppers. A squeeze of lemon juice draws out the flavorful juices while a few fresh cilantro leaves add a welcome brightness.
I can be a little overly ambitious when it comes to watermelon. I’ll grab a whole, field ripe watermelon from the market thinking surely we’ll have no problem eating our way through it, only to end up with way more than we can even cope with!
No matter how sweet it is, there’s just only so much plain cubed watermelon one can eat. So I took to developing some alternatives for this summertime treat. In addition to watermelon jam, refreshing watermelon green tea, and even freezing watermelon for another time, I had the idea for this sweet and spicy watermelon salsa.
The combination of ingredients is simple yet totally transforms the sweet watermelon into a punchy condiment that can be used as a dip (try it with tortilla or pita chips!), as a taco topping, as a component of your favorite grain bowl, or in any way you would use a classic salsa!
Watermelon Salsa Ingredients
- Jalapeño peppers – In addition to providing heat–it is a salsa after all!–I love the crisp crunch that jalapeños bring to the table. This is of course able to be tailored to suit any spice level, so add a lot of peppers if you like it hot or just a little bit if you prefer your salsa on the mellow side. If you aren’t adding very much jalapeño, I recommend subbing in a bit of green bell pepper so you can still get that crunch and color contrast.
- Lemon zest – Rich in citrus oils, the zest of the lemon is a powerhouse of flavor, adding a ton of brightness to this salsa.
- Red onion – I love the splash of color that red onion provides, but white onion would work too. The sharp raw flavor of the onion is nicely tamed by the acidic dressing as it chills before serving.
- Diced watermelon – Choose ripe, seedless watermelon if possible, otherwise you will have to go through and pick out any black seeds before mixing your watermelon into salsa. You can take a shortcut by picking up the pre-cubed watermelon that some grocery stores have, but depending on the size you may want to chop it up a bit smaller.
- Lemon juice – Fresh lemon juice is a must here, and you’ll have it on hand since we need the zest as well! I like the lemon flavor best for this recipe, but in a pinch, fresh lime juice will work too.
- Fresh cilantro – For me, it’s not salsa without a sprinkle of fresh cilantro! If cilantro isn’t your jam, chopped fresh basil leaves, fresh mint leaves, or parsley would be a nice option.
- Salt + Black pepper – Brings out the natural sweetness of the watermelon, and also helps to extract some of the fruit juices, making your salsa a little bit saucier!
Step-by-Step Instructions
- Chop jalapeños. Use a sharp knife to remove the stems from the jalapeño peppers, then slice them lengthwise. Use a spoon to scrape out the seeds and white membranes (unless you like things super spicy, then you can leave them in!), then finely dice the seeded peppers.
- Combine ingredients. In a bowl, combine all ingredients: the diced jalapeño pepper, lemon zest, chopped red onion, diced watermelon, lemon juice, cilantro, and a pinch of salt and black pepper. Toss gently until well mixed.
- Chill and serve. Refrigerate the salsa for 30 minutes, then toss it again before serving with chips for dipping!
Tips From Ligia
Get more juice from your lemon:
Pop the entire lemon into the microwave for just a few seconds; the heat will work to loosen up the juices inside. Then, roll the lemon between your palm and the counter top, pressing down as you do so. After this treatment it should produce more juice! This is especially helpful when you are dealing with lemons that are on the firmer, drier side.
How To Store
Refrigerating. Store your watermelon salsa in an airtight container in the fridge for up to 3 days. Though the flavors get better and more melded the longer it sits, the texture of the watermelon does start to suffer after a bit as it breaks down in the acidity so I recommend finishing this one up sooner than later!
