Grilled Watermelon with Lime
Juicy watermelon slices charred on the grill until smoky and caramelized, then finished with a squeeze of fresh lime and a sprinkle of flaky salt. The heat intensifies the watermelon's sweetness while adding a subtle savory depth, making this an unexpected summer side dish or light dessert that takes all of 10 minutes.
For 4 servings
- prep
Preheat the grill and prep the watermelon.
Preheat a grill or grill pan to high heat, about 450°F to 500°F. Brush both cut sides of each watermelon wedge lightly with olive oil.
TIPMake sure the grill grates are clean and very hot — this ensures clean grill marks and prevents sticking. - grill · ~6 min
Grill the watermelon wedges.
Place the oiled watermelon wedges directly on the hot grill grates. Cook for 2 to 3 minutes per side without moving them, until distinct char marks appear and the fruit is warmed through.
TIPResist the urge to move the wedges before the 2-minute mark — letting them sit undisturbed is what gives you those deep, smoky grill marks. - garnish
Finish with lime, salt, pepper, and mint.
Transfer the grilled watermelon to a serving platter. Squeeze the lime halves generously over the warm wedges, then sprinkle with flaky salt and cracked black pepper. Scatter the torn mint leaves on top and serve immediately.
TIPFlaky salt like Maldon adds a delicate crunch that kosher salt can't match — the contrast between sweet watermelon, smoky char, and crunchy salt is the whole point.
What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Cut wedges a full inch thick so they hold their shape on the hot grill without turning mushy.
- 2Pat the cut sides of the watermelon dry with paper towels before oiling for better charring.
- 3Use a grill brush to oil the grates just before placing the wedges to prevent sticking.
- 4If using a charcoal grill, bank the coals to one side for indirect heat in case wedges start to burn.
- 5Serve the watermelon within 5 minutes of grilling while the inside is still cool and the outside is warm.
- 6Leftover grilled watermelon can be chopped into salsa — just add jalapeño, red onion, and cilantro.
