This is a great recipe to accompany other grilled dishes like Cuban Mojo Grilled Chicken, Classic Burgers, or Grilled Cilantro Lime Shrimp. Tips on how to get distinct grill marks, as well as variations are listed below the recipe card.

Chef’s Note
To make sure the watermelon wedges come out with distinct, dark grill marks, I heat the grill to high before adding the fruit. This ensures that the melon will brown quickly. Additionally, you’ll also want to prep the grates with oil. This helps the fruit to cook, and makes sure the watermelon doesn’t get stuck to the grill.

Can this be made ahead of time?
I don’t recommend it. This is best served fresh, and since it grills up quickly, it’s a super stress free side to create.
How to Store
- Serve: After cooking, don’t leave sitting at room temperature for more than 2 hours.
- Store: To keep leftovers, place in an airtight container to store in the fridge for 2-3 days.
- Freeze: Watermelon won’t maintain its texture in the freezer. So, it’s better to enjoy this delicious dish fresh.
Variations
- Brown sugar: Enhance the natural sweetness by sprinkling with brown sugar instead of white sugar. The brown sugar caramelizes to make a rich, smoky, vanilla-like flavor. Another option is adding a drizzle of honey to the watermelon.
- Spicy: Add red pepper flakes or cayenne pepper to the watermelon marinade. Whisk it together with the sugar, lime zest, and kosher salt. Then sprinkle the spice mix before grilling. Be careful not to add too much spice. You can always add more spice to taste later.
- Seasonings: Sprinkle other seasonings over the grilled wedges, like mint leaves, fresh cilantro, or ginger.
- Mini watermelons: If you prefer, instead of slicing one giant melon, make this recipe using mini watermelons. You’ll still slice into wedge shapes before grilling.
- Kebabs: Chop the watermelons into cubes, then pierce them onto wooden kebabs to grill.
