BBQ Grilled Watermelon Recipe: Smoky Summer Twist

I’ve always been fascinated by the way smoke can transform ordinary ingredients into something extraordinary. Grilling watermelon adds a smoky depth that elevates this summer staple to new heights. The heat caramelizes the natural sugars, creating a complex flavor profile that’s both refreshing and savory.

This BBQ grilled watermelon recipe is perfect for summer gatherings. Simply brush watermelon wedges with olive oil, season with salt and pepper, and grill over medium-high heat for 2-3 minutes per side. The result is a beautifully charred exterior with a cool, refreshing interior. Serve as a unique side dish or add your favorite toppings for a show-stopping summer treat.

The watermelon matters here. Look for a ripe, firm melon with a creamy yellow spot on one end. Most grocery stores have decent ones, but farmers markets often have better options. The rind should be firm, not soft or mushy.

No balsamic glaze? Make your own by reducing balsamic vinegar on low heat until thick and syrupy. Feta adds a nice tang, but goat cheese works too. For a vegan version, skip the cheese and add some chopped fresh herbs like basil or mint.

Grilled watermelon keeps in the fridge for up to 3 days. Store leftovers in an airtight container. The flavors meld together nicely when chilled. You can also prep the toppings ahead—crumble the feta and chop the mint a day before.

Step-by-Step Instructions for BBQ Grilled Watermelon

Here’s the method to achieve perfectly grilled watermelon with a smoky twist.

Step 1: Prepare the Watermelon for Grilling

Start by cutting the 1 whole Seedless Watermelon into 1-inch thick slices. I like to cut them into triangular wedges or slabs, depending on the watermelon’s shape. Pat the slices dry with paper towels to remove excess moisture—this helps create a better sear on the grill.

Brush both sides of the watermelon slices with 2 tbsp Extra-Virgin Olive Oil. This prevents sticking and adds a subtle richness to the watermelon. Make sure to coat the edges as well since they’ll be exposed to the direct heat.

Step 2: Season and Grill the Watermelon

Preheat your grill to medium-high heat. I use a gas grill set to about 400°F, but charcoal works beautifully too if you prefer that smoky flavor. Season both sides of the watermelon slices with 0.5 tsp Kosher Salt and 0.25 tsp Black Pepper. Don’t be shy with the seasoning—the heat will mellow it out while enhancing the watermelon’s natural sweetness.

Place the watermelon slices on the preheated grill and cook for 2-3 minutes per side, or until you get nice char marks and a slight caramelization. You’ll see the edges start to develop a bit of crunch while the interior remains cool and refreshing.

Step 3: Garnish and Serve

Once grilled to your liking, transfer the watermelon slices to a serving platter. Sprinkle 0.25 cup Fresh Mint Leaves over the top—the heat from the watermelon will release the mint’s fragrance beautifully. If you’re using 0.5 cup Feta Cheese, crumble it over the watermelon now. The salty tang of the feta contrasts wonderfully with the sweet watermelon.

Finally, drizzle 2 tbsp Balsamic Glaze over the top if you’re using it. The glaze adds a rich, complex sweetness that ties all the flavors together. Serve immediately while the watermelon is still cool in the center and slightly warm on the edges.

Make-Ahead Tips for This Recipe

Pre-Grilling Preparation

To make grilling day easier, prepare your watermelon slices up to 24 hours in advance. Cut and store them in an airtight container in the refrigerator. You can also brush them with olive oil and season with salt and pepper ahead of time.

Make-Ahead Toppings

Prepare your toppings in advance to save time during serving. Crumble feta cheese and chop fresh mint up to a day before. Store them separately in airtight containers in the refrigerator. Having these ready makes assembly quick and easy.

Storage Tips

If you have leftover grilled watermelon, store it in an airtight container in the refrigerator for up to 3 days. While it’s best consumed fresh, the flavors actually meld together nicely when chilled. Note that texture may change slightly after refrigeration.

Balsamic Glaze Preparation

If you’re using balsamic glaze, you can make it ahead of time too. Reduce balsamic vinegar on low heat until thick and syrupy, then store it in a squeeze bottle in the refrigerator. It keeps for several weeks and is great to have on hand for other dishes.

Assembly and Serving

Assemble your grilled watermelon just before serving for the best presentation. Drizzle with balsamic glaze and sprinkle with fresh mint and feta cheese right before serving. This ensures everything looks fresh and appetizing. Serve immediately for the best flavor and texture.

Tips for Large Gatherings

For bigger gatherings, consider grilling watermelon in batches and keeping it warm on a cooler part of the grill or in a low-temperature oven (200°F). This allows you to serve a crowd without keeping everyone waiting. Have your toppings ready to go for quick assembly.
