Grilled watermelon turns an everyday summer fruit into something truly special—smoky, juicy, and caramelly at the edges. This simple recipe is my favorite for backyard parties because it never fails to surprise guests and spark conversation.
Every time I grill watermelon, I remember the first cookout my niece raced around barefoot, breathless with laughter, coming back just for more of these slices. Now she asks for this instead of dessert.
Ingredients
- Small seedless watermelon: It is best to choose one that feels heavy for its size and sounds hollow when tapped for the juiciest texture
- Olive oil extra virgin: Look for a fresh grassy scent high quality makes the glaze shine
- Balsamic vinegar: Aged if possible for sweet tangy complexity
- Honey or maple syrup: Adds balanced sweetness maple keeps it vegan
- Lime juice freshly squeezed: Brightens the flavors and helps the glaze stick
- Sea salt fine: Use good flaky salt to highlight the fruit
- Black pepper freshly ground: Fresh pepper adds a subtle kick and aroma
- Optional toppers: Feta cheese for savory contrast mint and basil for freshness chili flakes for heat drizzle of balsamic glaze for an elegant finish
Instructions
- Prepare the Watermelon:
- Slice off both ends then stand the watermelon upright and carefully cut off the rind in long downward strips try to remove all the pale green and white parts so only the bright red flesh remains Slice into one inch thick rounds called steaks Pat each slice thoroughly dry with paper towels as this helps them sear well on the grill
- Make the Balsamic Glaze:
- Whisk the olive oil balsamic vinegar honey or maple syrup lime juice sea salt and black pepper together in a small bowl Keep whisking until the dressing thickens and forms an emulsion Taste and tweak the balance for your liking
- Grill the Watermelon:
- Set your grill to medium high around three hundred seventy five to four hundred fifty degrees Use tongs and a paper towel dipped in oil to lightly grease the grates to prevent sticking Brush both sides of each watermelon steak generously with the glaze Place the slices directly on the hot grill Let them cook undisturbed for two to three minutes per side so they develop charred grill marks and become tender but not mushy If you get flare ups move the slices aside to a cooler area
- Remove and Serve:
- Lift the grilled watermelon off the grill and lay them on a clean platter While still warm top with your chosen extras such as crumbly feta torn mint or basil a sprinkle of chili flakes or a zigzag of balsamic glaze Serve and enjoy right away

The watermelon is always the star in this recipe I sometimes add a double squeeze of lime because my grandma believed citrus makes any fruit sing She always wanted a platter of these at our Fourth of July bash
