Watermelon Feta and Black Olive Salad shines with juicy watermelon sweetness mixed with salty olives and the tang of feta.

Ingredients

• 1 small red onion, chopped
• 2 limes, juiced (more if you prefer a stronger taste)
• 9 ounces crumbled feta cheese
• 3 pounds ripe watermelon, cut away from the rind and seeded, cut into bite-sized chunks roughly 1/4″ thick
• 1 bunch chopped fresh flat-leaf parsley (stems discarded)
• 1 small bunch chopped fresh mint
• 2 tablespoons extra-virgin olive oil
• 1/2 cup pitted, chopped Kalamata olives
• Freshly ground pepper

Instructions

1. Slice or chop the red onion and place it in a small bowl.
2. Juice the limes and pour the lime juice over the sliced red onion; let sit for a few minutes to marinate.
3. Stir the olive oil into the onion and lime mixture until combined.

4. Cut the watermelon away from the rind, seed as needed, and chop into ~1/4″ bite-sized chunks; place in a large bowl.

   

5. Chop the flat-leaf parsley and mint and sprinkle them over the watermelon.
6. Add the marinated red onion (with its lime and oil), and the chopped Kalamata olives to the watermelon.

9. Taste and adjust seasoning—add more lime juice and a pinch of sea salt if desired.

   

Notes

Kalamata olives can get pricey in regular grocery stores, so I stock up on the big jars at Costco—it’s a great deal and lasts forever.

When picking a watermelon, go for one that feels heavy for its size. Look for a creamy yellow spot on the bottom where it rested on the ground, that’s a good sign it’s ripe. Avoid watermelons with white or pale green spots.

If you happen to have an organic watermelon, don’t toss the rind! You can juice it too—I save mine to add to my smoothies or juice blends.

If you like a little extra flavor punch, sprinkle a pinch of sea salt on top—or try another savory-sweet option like this Strawberry Spinach Salad. I’m a big fan of smoked sea salt, which adds a subtle smoky depth depending on the type of wood the salt was smoked over.

How to Make the Salad

1. 1) Put the sliced red onion in a small bowl and pour the lime juice over it. Let it sit for a bit so the onion soaks up that bright lime flavor.

   2) After the onion has had time to marinate, stir in the olive oil until everything is combined nicely.

   3) In a big bowl, add the chopped watermelon, then sprinkle the fresh chopped mint and parsley over it. Pour in the red onion and lime juice mix along with the Kalamata olives.

   4) Gently toss the salad with your hands, so the juicy flavors get mixed in, but be careful not to mush the watermelon chunks.

   5) Finally, add the crumbled feta cheese and freshly ground pepper. Taste it and add more lime juice if you want a bit more zing.

1) Start by placing the sliced red onion in a small bowl and pouring the lime juice over it. Let it sit for a few minutes so the onion gets nice and tangy.

2) Once the onion soaks up the lime juice, add the olive oil and stir until it’s well combined.

3) Add the chopped watermelon to a large bowl, then sprinkle in the chopped mint and parsley. Toss in the limey red onions and Kalamata olives alongside the olive oil mixture.

4) Gently toss everything together using your hands. Be careful not to squash the watermelon chunks. You just want the flavors to blend without breaking up the fruit.

5) Finally, sprinkle the feta cheese on top, grind some fresh pepper over everything, and give it a final toss. Taste and add more lime juice if you want more zing.

1. 1) Place the sliced red onion in a small bowl and add the lime juice. Allow time for the red onion to absorb the lime juice.

   2) Once the red onion has absorbed the lime juice, add the olive oil and mix together.

   3) Place the cut watermelon in a large bowl. Sprinkle with chopped mint and parsley. Add the red onion, Kalamata olives, lime juice, and olive oil mixture to the watermelon.

   4) Hand toss the salad gently with your hands so the juice is mixed well with the watermelon, but you don’t damage the watermelon pieces.

   5) Add feta cheese to the watermelon salad and with freshly ground pepper. Add more lime juice to taste.

Smart Prep & Serving Tips

Kalamata olives can get pricey in regular grocery stores, so I stock up on the big jars at Costco—it’s a great deal and lasts forever.

When picking a watermelon, go for one that feels heavy for its size. Look for a creamy yellow spot on the bottom where it rested on the ground, that’s a good sign it’s ripe. Avoid watermelons with white or pale green spots.

If you happen to have an organic watermelon, don’t toss the rind! You can juice it too—I save mine to add to my smoothies or juice blends.

If you like a little extra flavor punch, sprinkle a pinch of sea salt on top. I’m a big fan of smoked sea salt, which adds a subtle smoky depth depending on the type of wood the salt was smoked over.

• Kalamata olives can be pricey at regular grocery stores. I save by buying huge jars at Costco—they last forever and are great quality.
• To pick a ripe watermelon, look for one that feels heavy for its size. The spot where it rested on the ground should be creamy yellow, which means it’s perfectly ripe. Skip any with white spots.
• If you manage to get an organic watermelon, don’t throw away the rind! I keep it to juice later or add to smoothies for extra flavor.
• A sprinkle of sea salt adds a nice touch of zing. I’m a big fan of smoked sea salt — it brings smoky depth depending on the wood used to smoke it.

Kalamata olives can be expensive at regular grocery stores. I buy a giant jar at Costco for a very reasonable price. 

To pick out a good watermelon, it should feel heavy for its size. The spot where the watermelon was on the ground should be a creamy yellow for optimal ripeness. (Avoid watermelon with white spots.) 

If you buy an organic watermelon, you can juice the rind. I save the rind until I make my juice and then add it to my mix.  

A sprinkling of sea salt can also give this recipe a little zing. My secret? I love smoked salt. Depending on the type of wood used, there are several different types of smoked sea salt.

Mix-Ins and Substitutions

• Make this salad vegan by swapping feta for a store-bought dairy-free feta or leaving out the cheese and adding toasted pistachios for a nice crunch.
• Add a handful of baby arugula or peppery watercress to bring some greenery and extra texture.
• If goat cheese is more your style, swap it for feta—it gives a creamier, tangier flavor that’s just as tasty.
• No Kalamata olives? No problem—try Castelvetrano or ripe black olives for a milder salty bite.
• Want extra savory? Add thinly sliced prosciutto, chunks of grilled halloumi cheese, or top with sliced grilled chicken for a heartier salad.
• For a fresh crunch boost, toss in diced cucumber or thin slices of red or yellow bell pepper for color and snap.
• Change up the dressing by drizzling balsamic reduction or switch the lime juice to lemon for a different citrus twist.
• For easy party bites, thread watermelon, feta cubes, olives, and mint onto skewers—perfect finger food. Or pair with pineapple BBQ pork skewers for a sweet-savory party spread.

Storage and Make-Ahead

Keep this salad in an airtight container in the fridge. It tastes best eaten within a day or two so it stays fresh and crisp. Avoid freezing it since watermelon turns mushy and watery when thawed. Planning a menu that needs to hold longer? Round it out with a make-ahead-friendly side like Honey Glazed Carrots & Green Beans.

Common Questions Answered

• Can I make this ahead?

  Absolutely! You can prep the red onion in lime juice and chop everything up a day before. For the freshest texture, mix the watermelon and dressing just before serving and add feta last. Stored well, it keeps nicely for a day or two.

• How do I keep the salad from getting watery?

  Choose firm, ripe watermelon cut into about 1/4” pieces as suggested. Drain any extra juice or chill the watermelon chunks on a tray so some liquid drips off before mixing everything. Toss gently to keep the pieces intact and add feta just before serving.

• Can I use seedless watermelon?

  Definitely. Seedless watermelon is super convenient and works perfectly in this recipe.

• What can I use instead of feta?

  Try crumbled goat cheese for a similar creamy tang or a dairy-free feta for a vegan version. If skipping cheese, toasted nuts like pistachios bring a nice crunch and richness.

• Are Kalamata olives essential?

  While Kalamatas add a lovely salty, fruity depth, you can swap them with other pitted olives like black or green olives you have on hand.

• Is the lime juice the only dressing?

  Yes, this salad keeps it simple with lime juice and extra-virgin olive oil acting as a fresh vinaigrette—similar to the zesty dressing on this Italian salad. Add a pinch of sea or smoked salt if you like to boost the savory flavor.

• How do I pick a ripe watermelon?

  Pick a watermelon that feels heavy for its size and has a creamy yellow spot on its underside—that’s a good sign it’s ripe and sweet. Avoid any with white or greenish spots.
