Grilled Halloumi Salad with Watermelon and Fresh Mint

Jump to Recipe

Grilled Halloumi and Watermelon Salad works because the cheese comes off the grill salty and squeaky while the watermelon stays cold and sweet. That temperature contrast is the whole point, and it’s why I never let the halloumi sit around before plating.

Halloumi has a high melting point, so it holds its shape on a hot grill pan instead of turning into a puddle. Two to three minutes a side is enough for deep golden stripes without the center going rubbery.

I build this on a platter rather than tossing everything in a bowl. Watermelon releases juice fast, and a bowl turns the arugula soggy within minutes.

Serve it right after the halloumi comes off the heat. Once it cools past lukewarm, the squeak disappears and the texture gets chewy instead of tender.

• Naturally gluten free and easy to keep vegetarian
• Works as a light lunch or a dinner starter

Ingredient Notes

• Halloumi: A firm, salty Cypriot cheese that holds its shape on the grill. Paneer works as a substitute but needs a light coating of oil since it has less fat.
• Watermelon: Pick a firm, ripe melon so the cubes hold together under the dressing. Seedless is easiest but any watermelon works if you cube around the seeds.
• Arugula: Adds a peppery base that stands up to the sweet watermelon. Baby spinach or watercress are good substitutes.
• Fresh mint: Torn mint keeps the salad bright and cuts the richness of the cheese. Basil is a reasonable swap if that’s what you have.
• Red onion: Soak the slices in cold water for 5 minutes to soften the sharp bite before adding to the salad.
• Lime juice: The acid balances halloumi’s salt. Lemon juice works the same way.
• Pistachios: Toasted and chopped, they add crunch and a little fat. Pine nuts or slivered almonds work too.
• Balsamic glaze: Optional but adds a sweet-tangy finish. Skip it or swap in a mix of honey and a splash of vinegar.

Ingredients

  

For the Salad

• 600 g Watermelon, seedless cut into 1-inch cubes
• 250 g Halloumi cheese sliced 1 cm thick
• 60 g Arugula
• 1/4 Red onion small; thinly sliced
• 15 g Fresh mint torn, about a small handful
• 30 g Pistachios toasted and roughly chopped

For the Dressing

• 3 tbsp Extra-virgin olive oil 1 tbsp for grilling, 2 tbsp for drizzling
• 1 tbsp Lime juice fresh
• 1 tbsp Balsamic glaze optional
• Flaky sea salt to taste
• Black pepper to taste
• Chili flakes a pinch; optional

Method

 

Prep the Watermelon and Base

1. Cut watermelon into 1-inch (2.5 cm) cubes and chill in the fridge while you prep everything else.
2. Slice red onion thin and soak in cold water for 5 minutes to soften the bite, then drain.
3. Arrange arugula in an even layer on a large serving platter.

Grill the Halloumi

1. Slice halloumi into 1 cm-thick pieces and pat dry with a paper towel.
2. Heat a grill pan or outdoor grill over medium-high heat, about 200 C / 390 F, until hot.
3. Brush halloumi lightly with olive oil and grill 2 to 3 minutes per side, until deep golden grill marks form, the edges crisp, and the center stays soft.
4. Remove halloumi from the heat right away, it firms up fast once off the pan.

Assemble and Serve

1. Scatter chilled watermelon cubes and drained red onion over the arugula.
2. Top with the warm grilled halloumi slices.
3. Drizzle with olive oil, lime juice, and balsamic glaze.
4. Scatter torn mint and toasted pistachios over the top, then finish with black pepper and chili flakes if using.
5. Serve right away while the halloumi is still warm.

Notes

• Grill halloumi last so it hits the plate still warm.
• Cube watermelon large enough that it doesn't turn mushy under dressing.
• Soak red onion in cold water to cut the sharp bite.
• Toast pistachios dry for 2 minutes before scattering, no oil needed.

Tips for Success

• Pat halloumi slices dry before grilling so they sear instead of steam.
• Cut watermelon into large cubes so they hold their shape under the dressing.
• Grill halloumi directly before serving since it turns rubbery within 15 minutes of cooling.
• Chill the watermelon separately so the halloumi stays the only warm element on the plate.
• Toast pistachios in a dry skillet for 2 minutes to deepen their flavor before scattering.

Variations

• Swap watermelon for ripe peaches in late summer for a similarly juicy, less sweet base.
• Add thin cucumber ribbons for extra crunch and a cooling contrast to the salty cheese.
• Finish with a chili-lime drizzle instead of balsamic glaze for a spicier, brighter edge.

Storage and Reheating

Grilled Halloumi and Watermelon Salad doesn’t hold well once assembled, since the watermelon weeps juice and the halloumi softens within an hour. If you have leftovers, expect a softer texture and more liquid on the plate.

Store any leftover components separately in airtight containers in the fridge for up to 2 days. Keep the watermelon, dressing, and cooked halloumi apart so nothing turns soggy.

To reheat, warm the halloumi in a dry skillet over medium heat for about 1 minute per side, just until it firms up again. Add it back to cold watermelon and greens right before eating.

Serving Suggestions

Grilled Halloumi and Watermelon Salad works as a starter before grilled chicken skewers or lamb kofta wraps, or as a light lunch with warm pita and hummus on the side.

For a more filling meal, add it alongside a bulgur or orzo pilaf so the plate has something starchy to balance the salad’s brightness.

A dry rosé or sparkling water with lime matches the sweet-salty profile well and doesn’t compete with the mint.

FAQ

Why is my grilled halloumi rubbery instead of soft in the center?

Rubbery halloumi usually means it sat too long after grilling or cooked past 3 minutes per side. Halloumi firms up fast once it cools, so serve it within a few minutes of coming off the pan. Keep the heat medium-high and pull the slices as soon as you see deep golden grill marks, before the edges curl.

Can I use feta instead of halloumi in this watermelon salad?

You can, but feta won’t grill the same way since it crumbles and melts instead of holding its shape. Skip the grill step and crumble raw feta over the salad instead, or look for a firm sheep’s milk feta that can handle brief grilling on foil. The salty-sweet balance with watermelon still works either way.

Can I make grilled halloumi and watermelon salad ahead of time?

You can prep the components ahead but should assemble right before eating. Cube the watermelon and slice the onion up to a day ahead and keep them chilled separately, but grill the halloumi fresh since it turns chewy and loses its squeak within 15 minutes of cooling.

What goes well with grilled halloumi and watermelon salad?

Grilled chicken skewers, lamb kofta, or warm pita with hummus round this out into a full meal. The salad also works alongside orzo or a bulgur pilaf if you want something more filling. A dry rosé or sparkling water with lime matches the sweet-salty profile well.

Is grilled halloumi and watermelon salad gluten free?

Yes, this salad is naturally gluten free since halloumi, watermelon, arugula, and the lime-olive oil dressing contain no wheat or gluten ingredients. Just double check your balsamic glaze label, since some bottled versions include thickeners that aren’t gluten free.

What’s the difference between halloumi and paneer for grilling?

Halloumi holds its shape better on a hot grill because the curds are heated during production, giving it a higher melting point and a dense, squeaky bite. Paneer is milder and softer, and needs a light coating of oil to keep it from sticking, while halloumi’s own fat handles that job.
