Grill Your Watermelon Wedges For The Ultimate Salty-Sweet Summer Treat

Don't sweat it — it can take the heat. (And it makes a beautiful balsamic salad, too.)

Arriving at home with a whole watermelon is a treat — and a commitment. I hate wasting food, and who’s kidding who, there are only so many days that slices of watermelon stay crisp and appealing. So now when I purchase a whole watermelon, I do it with a plan. After tossing it into salads and blending it into cold soups and gelatos, I apply some heat. It’s time to grill.

How to grill watermelon

The method for grilling watermelon is simple: use oil and seasoning, adding whatever flavours you choose to accompany it. I make grilled watermelon with fresh basil, balsamic and cracked black pepper – and it’s awesome! Because watermelon has such a high water content, it works best to let the slices sit on a few layers of paper towel to absorb the surface water, which will let the oil adhere better. Also, leave the rind on while you grill to make it easier to flip.
