This salad is 20 minutes start to finish: halloumi gets a quick sear, watermelon gets cubed, everything goes on a platter. The honest reason to make it is that grilled halloumi holds its shape and stays warm long enough to eat without rushing, which makes it genuinely useful on a busy evening rather than just a weekend project.
Before you start
The one thing that will make or break this recipe is a dry, hot pan. Pat the halloumi slices completely dry with paper towels before they go anywhere near the grill or pan — any surface moisture creates steam and you lose the golden crust. The pan needs to be properly preheated before the cheese touches it; if it sizzles immediately on contact, you’re ready. A lukewarm pan means the halloumi sticks and tears instead of releasing cleanly after two minutes. Everything else in this recipe is forgiving, but that first contact between cold wet cheese and a cool surface is where most people go wrong.
Troubleshooting
- Halloumi is rubbery, not golden: The pan wasn’t hot enough, or the slices were too thick. Aim for a true half-inch — thicker than that and the outside overcooks before the inside warms through. If your halloumi is already cut thicker, add 30 seconds per side.
- Salad is watery by the time it hits the table: Watermelon releases liquid fast once it’s cut and dressed. Don’t dress the salad until you’re ready to serve, and if you’re slicing the watermelon more than 10 minutes ahead, keep it in a colander over a bowl so excess juice drains away.
- Pistachios taste flat: Pre-chopped or pre-packaged pistachios often lose their flavor. Buy them whole, toast them in a dry pan for 2–3 minutes over medium heat until fragrant, then chop. Skip the garnish of extra whole pistachios on top — not worth the extra dish.
- Dressing tastes sharp or one-note: Lime juice strength varies a lot by fruit. Taste the dressing before it goes on — if it’s too sharp, add a small drip more honey or a tiny pinch of extra salt to round it out. If it’s flat, add a few more drops of lime.
- Halloumi cooled down and turned chewy before serving: Halloumi firms up quickly as it cools. Grill it last, after everything else is already on the platter, and add it straight from the pan.
Make-ahead notes
The dressing can be whisked together up to 3 days ahead and kept in a sealed jar in the fridge — give it a shake before using. The watermelon can be cubed and refrigerated in an airtight container for up to 24 hours, though it softens slightly after that. Arugula and mint can be washed and dried up to a day ahead, stored wrapped in a paper towel in the fridge. Halloumi does not reheat well — it turns dense and squeaky — so grill it fresh right before serving. There is no useful freezer application for any component of this salad.
Grilled Halloumi and Watermelon Salad
Equipment
- Grill pan or outdoor grill
- Sharp Knife
- Mixing bowl
- Tongs
- Serving platter
Ingredients
For the Salad:
- 8 oz halloumi cheese sliced into ½-inch thick slabs
- 4 cups watermelon seedless, cut into bite-sized cubes
- 1 cup arugula leaves fresh and washed
- ¼ cup pistachios lightly toasted and chopped
- ¼ cup fresh mint leaves torn into small pieces
For the Dressing:
- 3 tbsp extra virgin olive oil high quality for best flavor
- 1 tbsp fresh lime juice preferably from a ripe lime
- 1 tsp honey optional, for a touch of sweetness
- ½ tsp sea salt adjust to taste
- ¼ tsp freshly ground black pepper
Instructions
- Preheat a grill pan or outdoor grill to medium-high heat (about 375°F / 190°C).
- Lightly brush the halloumi slices with a small amount of olive oil to prevent sticking.
- Place the halloumi slices on the preheated grill and cook for about 2 minutes per side, or until golden brown grill marks appear. Remove from heat and set aside to cool slightly.
- In a small bowl, whisk together the olive oil, fresh lime juice, honey (if using), sea salt, and black pepper to create the dressing.
- In a large mixing bowl, gently toss the watermelon cubes, arugula leaves, and mint.
- Arrange the salad mixture on a serving platter and top with the grilled halloumi slices.
- Drizzle the dressing over the salad and sprinkle with toasted pistachios.
- Serve immediately and enjoy this refreshing Mediterranean salad!
Notes
- For an extra layer of flavor, try adding a drizzle of balsamic glaze over the finished salad.
- If halloumi is unavailable, feta cheese can be a great substitute.
- This salad pairs wonderfully with grilled seafood or a chilled glass of Sauvignon Blanc.

Frequently asked questions
Can I use a regular skillet instead of a grill pan?
Yes, a cast iron or stainless steel skillet works well. You won’t get grill marks, but the crust and flavor are essentially the same — what matters is the high heat, not the ridges.
Where do I find halloumi cheese?
Most large grocery stores carry it in the specialty cheese section, often near feta or imported cheeses. Trader Joe’s, Whole Foods, and Middle Eastern grocery stores are reliable sources if your regular store doesn’t stock it.
Can I substitute feta if I can’t find halloumi?
Feta works as a substitute but you won’t be grilling it — just crumble it over the finished salad cold. The flavor is similar but the texture is softer and crumbly rather than warm and chewy, so the eating experience is different.
How do I know if my watermelon is ripe enough?
A ripe watermelon has a deep, hollow sound when you knock on it and a creamy yellow field spot on the underside. Avoid any that sound dull or have a white or pale green field spot — they’ll be watery and bland, which throws off the whole salad.
Is the honey in the dressing necessary?
No, it’s optional. If your watermelon is already very sweet and ripe, leave the honey out entirely — the dressing is well-balanced without it. Add it only if your watermelon tastes mild or your lime is particularly tart.
Can I make this salad for a larger group?
Yes, the recipe scales up straightforwardly — double or triple all quantities. The only practical limit is your grill pan size; cook the halloumi in batches and keep finished slices on a warm plate in a low oven (around 200°F) for up to 5 minutes while you finish the rest.
