Ingredients for Grilled Watermelon
You only need four main ingredients:
- 1 medium seedless watermelon, about 3 pounds
- 2 limes, juiced and zested, about 2 tablespoons juice and 2 teaspoons zest
- 1/4 cup honey
- 1/4 cup loosely packed fresh cilantro leaves, finely chopped
Choosing the Best Watermelon for Grilling
Start with a medium seedless watermelon. Seedless fruit makes the wedges easier to eat, especially when you serve them straight from the grill.
Also, choose a watermelon that feels heavy for its size. You want firm flesh because it handles high heat better and keeps its shape.
Honey, Lime, and Cilantro Flavoring
Honey and lime make a simple coating that tastes especially good once the grill heats it. The honey sweetens the surface, while lime juice and zest bring fresh acidity.
Meanwhile, cilantro adds a bright herbal note at the end. As a result, the finished fruit tastes smoky, sweet, citrusy, and fresh rather than simply sugary.
How to Cut Watermelon for Grilling
First, trim both ends from the watermelon. Next, stand it upright on one flat end and cut it in half.
Then, cut each half into quarters. This method gives you manageable sections and makes slicing much easier.
Cutting 1-Inch-Thick Watermelon Wedges
Cut each quarter into triangular wedges about 1 inch thick. Try to keep the thickness fairly even so every piece cooks at about the same speed.
You should get roughly 20 pieces. However, the exact number can change with the size and shape of your watermelon.
Why You Should Leave the Rind On
Keep the rind attached to every wedge. It acts like a natural handle, so you can move and eat the warm fruit more easily.
Also, the rind helps support the softened flesh. Therefore, your Grilled Watermelon stays easier to handle after those juicy centers meet the hot grill.
How to Make Grilled Watermelon
Make the Honey-Lime Mixture
First, whisk the lime juice, lime zest, and honey together in a small bowl. Keep whisking until the mixture looks smooth.
Meanwhile, heat an outdoor grill or indoor grill pan to high heat.
Brush the Watermelon Wedges
Next, coat both sides of every watermelon wedge with the honey and lime mixture. Cover the surface lightly rather than soaking the fruit.
Also, keep a little fresh lime nearby. You will use it to brighten the wedges right before serving.
Grill the Watermelon Over High Heat
Place the wedges on the hot grill. Then, grill them for 2 to 3 minutes per side.
Watch for strong grill marks and slight softening. However, remove the fruit before the center turns overly soft. Grilled Watermelon tastes best when it still has some juicy bite.
Add Cilantro and Fresh Lime
Finally, sprinkle the warm wedges with finely chopped cilantro. Then, squeeze fresh lime juice over the top.
Serve them right away. The contrast between warm charred edges and juicy fruit makes this simple recipe especially fun to eat.
Tips for Perfect Grilled Watermelon
Use High Heat for Better Grill Marks
Use high heat from the start. Because watermelon contains plenty of water, quick cooking helps you create dark grill marks without turning the flesh too soft.
Also, let the grill get fully hot before adding the wedges.
Oil the Grill Grates to Prevent Sticking
Lightly oil clean grill grates before cooking. This small step helps the honey-coated watermelon release more easily.
Then, give each piece time to develop grill marks before you turn it.
Avoid Overcooking the Watermelon
Grilled Watermelon needs only 2 to 3 minutes on each side. So, stay close to the grill.
If you cook it much longer, the fruit can lose its firm texture. Instead, aim for a slightly softened center with visible char marks outside.
Let Excess Watermelon Juice Drain
After grilling, you can set the wedges on a wire rack over a baking sheet. Then, excess juice can drip below instead of pooling around the fruit.
This trick especially helps when you need a few minutes to arrange the rest of lunch.
Grilled Watermelon Seasoning Variations
Spicy Grilled Watermelon with Tajín or Chili Powder
For extra heat, add about 2 teaspoons of Tajín, chili powder, or cayenne. The spice works well with the sweet watermelon and honey.
Also, lime ties those flavors together. As a result, you get a sweet, spicy, smoky combination that works nicely at a barbecue.
Caramelized Grilled Watermelon with Sugar
For a sweeter surface, replace the honey with granulated sugar. Coconut sugar works too.
Then, the sugar caramelizes against the hot grill and creates deeper sweetness around the edges.
What to Serve with Grilled Watermelon
Serve It as a Summer Lunch or Barbecue Side
Serve Grilled Watermelon beside burgers, grilled chicken, or vegetables for an easy summer meal. It also makes a refreshing appetizer before heavier barbecue dishes.
For another grill friendly pairing, try a grilled vegetables marinade or serve the fruit beside garlic Parmesan grilled corn on the cob.
Turn Grilled Watermelon into a Cotija Salad
You can also remove the rind and cube the cooked fruit. Then, toss it with cotija cheese, fresh cilantro, and lime juice.
The salty cheese contrasts nicely with the warm, sweet fruit. Meanwhile, lime keeps the salad fresh and lively.
How to Store Leftover Grilled Watermelon
Grilled Watermelon tastes best immediately after cooking. That way, you get the strongest contrast between the smoky exterior and juicy center.
However, you can still save leftovers. Place cooled pieces in an airtight container and keep them refrigerated.
How Long Grilled Watermelon Lasts in the Fridge
Store leftovers in the refrigerator for 4 to 5 days. However, expect the watermelon to soften and release more liquid as it sits.
For that reason, I prefer serving leftovers cold in a salad rather than trying to recreate that fresh grilled texture.
