Step‑by‑Step Instructions for Watermelon Salad with Red Onion
Step 1: Prepare the Ingredients
Begin by choosing a perfectly ripe watermelon, which should feel heavy for its size. Using a sharp knife, cut the watermelon in half, then slice each half into manageable sections. Cube the watermelon flesh into bite-sized pieces, ensuring a juicy, vibrant display. Next, take a red onion and thinly slice it to achieve that milder, sharper flavor that will enhance the overall freshness of your Watermelon Salad with Red Onion.
Step 2: Combine the Main Ingredients
In a large mixing bowl, gently combine the cubed watermelon and thinly sliced red onion. Add crumbled feta cheese to the bowl for that creamy, salty kick. Take a moment to admire the beautiful colors and textures—this is a salad that’s as pleasing to the eye as it is to the palate. Use a spatula to ensure all ingredients mingle without breaking the delicate watermelon pieces.
Step 3: Add the Dressing
Drizzle a couple of tablespoons of extra virgin olive oil and freshly squeezed lime juice over the salad mixture. The olive oil enhances richness, while the lime juice brightens the flavors. For a sweeter alternative, consider honey. This dressing will tie all the components together beautifully, creating a refreshing and zesty finish for your Watermelon Salad with Red Onion.
Step 4: Toss Gently
With careful, smooth motions, gently toss the salad ingredients together. Aim to combine without crushing the watermelon cubes or losing the feta’s crumbly texture. You want to retain the crunch of the red onion while allowing all flavors to meld naturally. This step is key—aim for a cohesive mix that showcases each component’s individual charm.
Step 5: Garnish and Serve
To finish, sprinkle fresh mint leaves over the salad for a burst of cooling freshness. If you prefer, basil makes a great alternative for sweetness. This Watermelon Salad with Red Onion is best served immediately, as the fresh mint will retain its vibrant color and taste. Present it in a beautiful serving bowl and prepare to delight your guests with this refreshing summer dish!

Expert Tips for Watermelon Salad
• Choose Ripe Watermelon: Look for a heavy watermelon with a uniform color and a creamy spot—this indicates ripeness for the best flavor.
• Mild Onion Flavor: Soak sliced red onion in cold water for about 10 minutes before adding it to the salad; this softens its bite and harmonizes the flavors.
• Fresh Ingredients: Always use fresh mint for the best vibrant taste; dried herbs won’t provide the same refreshing kick in your Watermelon Salad with Red Onion.
• Creamy Alternatives: If you prefer a different flavor profile, swap feta for creamy goat cheese or fresh mozzarella for a lighter touch.
• Add Crunch: Want more texture? Consider tossing in diced cucumbers or even a handful of toasted nuts—these add delightful crunch to your salad.

Watermelon Salad with Red Onion Recipe FAQs
How do I choose the perfect watermelon?
Absolutely! When selecting a watermelon, look for one that feels heavy for its size and has a uniform color. A creamy spot indicates ripeness, as it shows where it rested on the ground, forming sweetness. Avoid watermelons with dark spots all over, as those could indicate overripeness.
How do I store leftover watermelon salad?
To maintain the freshness of your Watermelon Salad with Red Onion, store any leftovers in an airtight container in the refrigerator for up to 2 days. If you plan ahead, consider keeping the watermelon, onion, and feta in separate containers to prevent excess moisture from affecting the texture.
Can I freeze watermelon salad?
No need to freeze this salad! Watermelon loses its structure once thawed, resulting in a mushy texture that doesn’t pair well with the salad’s fresh components. I recommend consuming it fresh for the best experience.
What can I do if my red onion is too strong?
Very handy tip! Soak the thinly sliced red onion in cold water for about 10 minutes before mixing it into your salad. This simple trick softens its bite, resulting in a milder flavor that melds beautifully with the sweet watermelon.
Is this watermelon salad suitable for my pets?
While watermelon is generally safe for pets, be cautious with the feta cheese, as some dogs may have lactose intolerance. Always consult your veterinarian when introducing new foods to your pet’s diet. This Watermelon Salad with Red Onion is a delightful treat for humans, so whip it up for yourself instead!
Can I adjust the recipe for dietary restrictions?
Of course! If you’re looking for alternatives, swap feta with goat cheese or fresh mozzarella. For vegan options, consider using marinated tofu or chickpeas for creaminess. The salad is already vegetarian-friendly, making it an adaptable and inclusive dish for various dietary preferences.
