The heat concentrates the melon's natural sugars, creating a stunning contrast of caramelized edges and cool, refreshing centers.

Make the balsamic glaze.
Pour balsamic vinegar and honey into a small saucepan. Bring to a boil, then reduce heat to a gentle simmer. Cook until it coats the back of a spoon and reduces by half, about 10 to 12 minutes. Remove from heat and let cool; it will thicken as it cools.
TIPDon't walk away — balsamic can burn in seconds. Swirl the pan occasionally instead of stirring too much. - prep · ~5 min
Preheat the grill or grill pan.
Heat a grill pan or outdoor grill to medium-high. The grates should be hot enough that water droplets sizzle and evaporate instantly.

TIPKeep the rind on. It acts as a handle and helps the wedge hold its shape on the grill. - grill · ~6 min

What to keep in mind.
5 tips from the recipe — small details that make a real difference to the final dish.
- 1Pat the watermelon wedges bone-dry before grilling to ensure deep char marks instead of steaming.
- 2Grill the wedges at a slight angle to the grates for those classic crosshatch grill marks.
- 3Keep the rind on the watermelon wedges — it acts as a natural handle and helps the slice hold its shape.
- 4Let the balsamic glaze cool completely before drizzling; it will thicken and cling better to the melon.
- 5Serve the dish immediately while the watermelon is still warm for the best hot-cold, sweet-savory contrast.
Adapt it for your goals.
Vegan
Omit the feta cheese and use a vegan crumble made from soaked cashews blended with lemon juice and salt, or simply skip the cheese and add toasted pine nuts for crunch.
spicySpicy
Add a pinch of red pepper flakes or a thin slice of fresh jalapeño to the balsamic glaze while it simmers for a heat that contrasts with the cool melon.
herb swapHerb-swap
Replace fresh mint with torn basil or cilantro for a different aromatic profile — basil pairs beautifully with balsamic, while cilantro leans into a bright, savory finish.
cheese swapCheese-swap
Substitute crumbled feta with fresh goat cheese, ricotta salata, or even blue cheese for a tangier, creamier, or bolder flavor.
Why this is on our healthy list.
Hydrating & Low-Cal
Watermelon is over 90% water, making this a refreshing, low-calorie dish that helps keep you hydrated on hot days.
Rich in Lycopene
Watermelon is a top source of lycopene, a powerful antioxidant linked to heart health and reduced inflammation. Grilling may even make the lycopene more bioavailable.
Good Source of Calcium
Feta cheese contributes a modest amount of calcium for bone health, and its saltiness provides electrolytes.
Digestive Aid from Mint
Fresh mint adds a cooling finish and is traditionally used to soothe the stomach and aid digestion.
Frequently asked questions
You can, but the flavor will change. Balsamic's natural sweetness and syrupy body are key. For a substitute, use a good balsamic glaze from the store, or reduce a mix of red wine vinegar and a little brown sugar.
