Ingredients

For this refreshing Watermelon Cucumber Salad, you’ll need:

• 6 cups watermelon, cubed (about ½ medium watermelon or 2.5 lbs/1.1 kg)
• 2 medium cucumbers, sliced (about 2 cups or 300g) – English or Persian varieties work best for their crisp texture and minimal seeds
• ¼ cup fresh mint leaves, chopped
• ¼ cup fresh basil leaves, torn (optional but recommended)
• ½ small red onion, thinly sliced (about ⅓ cup)
• ¾ cup feta cheese, crumbled (about 4 oz/115g) – use a good quality brined variety
• ⅓ cup kalamata olives, pitted and halved (optional)

For the dressing:
• 3 tablespoons extra virgin olive oil
• 2 tablespoons fresh lime juice (from about 1 lime)
• 1 tablespoon honey (or maple syrup for vegan option)
• ½ teaspoon sea salt
• ¼ teaspoon freshly ground black pepper
• 1 clove garlic, minced (optional)

The key to exceptional flavor is using peak-season watermelon that’s sweet and ripe, and crisp cucumbers without bitter skin.

Pro Tips

Master your Watermelon Cucumber Salad with these three game-changing techniques:

First, properly prepare your watermelon by chilling it thoroughly before cutting. This not only makes the salad more refreshing but also helps the watermelon maintain its structure when mixed with other ingredients. For perfect cubes, use a sharp knife and aim for 1-inch pieces—large enough to provide that juicy bite but small enough to easily combine with other ingredients.

Second, address cucumber moisture strategically. After slicing your cucumbers, place them in a colander, sprinkle lightly with salt, and let them sit for 10 minutes. This draws out excess moisture that would otherwise make your salad watery. Pat them dry with paper towels before adding to your salad. For English cucumbers, there’s no need to peel or seed them; for regular cucumbers, consider peeling and removing the seed core.

Third, master the art of dressing timing. Unlike hearty salads that benefit from marinating, this fresh cucumber watermelon mixture should be dressed just before serving. If preparing in advance, keep all components separate and combine at the last moment. This preserves the crisp texture of the cucumber and prevents the watermelon from releasing too much juice, ensuring your salad remains vibrant rather than soggy.

Instructions

Step 1: Prepare the Watermelon

Start by selecting a ripe, sweet watermelon—look for one that feels heavy for its size and has a deep, hollow sound when tapped. Rinse the outside thoroughly, then cut it in half and place it cut-side down on your cutting board. Slice away the rind, then cut the flesh into 1-inch cubes. If you’re working ahead, place your watermelon cubes in a colander over a bowl to allow any excess juice to drain away.

Step 2: Prepare the Cucumbers

For the cucumbers, wash them thoroughly and decide whether to peel them based on the variety you’re using. For English or Persian cucumbers, you can leave the skin on for added color and nutrients. Slice the cucumbers in half lengthwise, then cut into ¼-inch thick half-moons. If using regular cucumbers with large seeds, scoop out the seeds before slicing to prevent excess moisture in your Watermelon Cucumber Salad.

Step 3: Prep the Remaining Ingredients

Wash and dry your fresh herbs, then roughly chop the mint and tear the basil leaves (if using) to release their aromatic oils without bruising them too much. For the red onion, slice it as thinly as possible—using a mandoline if you have one—then soak the slices in ice water for 5-10 minutes to remove some of the sharp bite before draining and patting dry.

Step 4: Make the Dressing

In a small bowl, combine the olive oil, fresh lime juice, and honey. Whisk vigorously until emulsified, then add the minced garlic (if using), salt, and pepper. Taste and adjust the seasoning—you’re looking for a balance of tangy, sweet, and savory notes that will complement the fresh watermelon cucumber combination.

Step 5: Assemble the Salad

In a large bowl, gently combine the watermelon cubes and cucumber slices. Add the sliced red onion and about half of your herbs. Drizzle about two-thirds of the dressing over the mixture and toss gently with clean hands or wooden spoons to coat everything evenly without crushing the delicate ingredients.

Step 6: Final Touches

Just before serving, sprinkle the crumbled feta cheese, remaining herbs, and kalamata olives (if using) over the top of your Watermelon Cucumber Salad. Drizzle the remaining dressing and finish with a few grinds of fresh black pepper. Serve immediately to enjoy the optimal texture and flavor combination.

Variations

The classic Watermelon Cucumber Salad is just the beginning—here are some delicious variations to keep this refreshing dish exciting all summer long:

For a spicy twist, try a Mexican-inspired variation by adding 1 diced jalapeño (seeds removed for less heat), substituting cilantro for mint, and adding a sprinkle of Tajin seasoning or chili powder. The heat beautifully balances the cool sweetness of the watermelon cucumber combination, creating an unexpected flavor profile that’s perfect for taco nights.

For a more substantial Mediterranean version, transform this into a complete meal by adding 1 cup of cooked quinoa or pearl couscous, a can of drained chickpeas, and extra feta cheese. Enhance the dressing with a teaspoon of dried oregano and use red wine vinegar instead of lime juice. This hearty variation makes for a perfect packed lunch that won’t wilt by midday.

For dietary restrictions, create a vegan watermelon cucumber dish by omitting the feta cheese and adding diced avocado for creaminess, plus a tablespoon of nutritional yeast in the dressing for a subtle cheesy flavor. Alternatively, for a keto-friendly option, increase the feta cheese, add diced avocado, and substitute the honey in the dressing with a keto-approved sweetener.

Storage and Serving

This Watermelon Cucumber Salad is best enjoyed fresh, ideally within 2 hours of preparation when the textures and flavors are at their peak. If you need to store leftovers, transfer them to an airtight container and refrigerate for up to 24 hours, knowing that the texture will soften somewhat as the watermelon continues to release its juices.

For make-ahead convenience, prepare all components separately—cube the watermelon, slice the cucumber, make the dressing—and store them individually in the refrigerator for up to 2 days before assembling just before serving.

Serve this vibrant salad in a large white bowl to showcase its beautiful colors, or for an impressive presentation, hollow out half a watermelon and use the rind as a natural serving bowl. This watermelon cucumber mixture pairs beautifully with grilled chicken or fish, makes a refreshing side for spicy barbecued meats, or stands alone as a light lunch alongside crusty bread.

For an elegant dinner party twist, serve individual portions in chilled martini glasses or on small beds of arugula, garnished with extra mint and a light drizzle of high-quality olive oil. For casual gatherings, offer it with wooden serving utensils in a large bowl, allowing guests to help themselves to this crowd-pleasing summer staple.

FAQs

How do I pick the best watermelon for my Watermelon Cucumber Salad?
Look for a watermelon that feels heavy for its size with a creamy yellow (not white) spot where it sat on the ground. It should have a hollow sound when tapped. For this salad, seedless varieties work best but aren’t essential.

Can I make this salad ahead of time?
You can prepare the components up to 24 hours ahead, but it’s best to assemble just before serving. If you must make it ahead, hold the dressing and feta until the last minute to maintain optimal texture.

My cucumber seems bitter. What should I do?
Cucumber bitterness is concentrated in the skin and ends. Peel the cucumber and cut off about ½ inch from each end. For regular cucumbers, also remove the seedy center which can be bitter.

Is there a substitute for feta cheese?
Yes! Try goat cheese for a creamier texture, cotija for a Mexican-inspired version, or omit cheese entirely and add diced avocado for creaminess without dairy.

How can I make my Watermelon Cucumber Salad less watery?
Salt and drain your cucumbers for 10 minutes before adding them to the salad. Also, drain your watermelon cubes in a colander for a few minutes, and add the dressing just before serving rather than letting it sit.
