Grilled Watermelon with BBQ Lime Glaze is a unique summer BBQ side or dessert that caramelizes juicy watermelon over the grill and finishes it with a tangy, smoky lime-infused barbecue glaze. This easy grilled watermelon recipe is refreshing, unexpected, and perfect for cookouts, BBQ spreads, and plant-forward grilling.
Heat grill to medium-high heat (400–425°F / 205–220°C).
Clean and lightly oil grates to prevent sticking.
In a small bowl, whisk BBQ sauce, lime zest, lime juice, honey, smoked paprika, chili flakes, and salt.
Set aside.
Pat watermelon wedges dry.
Lightly brush with oil if desired (helps grill marks but optional).
Place wedges directly on grill grates.
Grill 2–3 minutes per side, until grill marks form and surface caramelizes.
Flip carefully—watermelon softens as it heats.
Brush watermelon lightly with BBQ lime glaze during the final minute on each side.
Remove from grill and rest 1–2 minutes.
Drizzle with extra glaze.
Garnish with herbs or cheese if using.
Serve warm or slightly cooled.

Use ripe but firm watermelon—overripe slices will collapse.
Don’t over-glaze; watermelon should stay fresh and juicy.
Chili flakes add balance, not heat—use lightly.
Thick slices hold up best on the grill.
Leftovers are excellent chilled and cubed into salads.
