It sounds weird at first, but once you try grilled watermelon, you’ll wonder why you didn’t fire up the grill sooner.
 
The process is simple, the ingredients are minimal, and the payoff is huge.
 
In this post, we’ll walk through exactly how to grill a watermelon, the best ways to season it, and a few tasty ideas for serving it.
 
Let’s get grilling.
 

How to Grill a Watermelon Perfectly Every Time

Learning how to grill a watermelon comes down to a few key steps: picking the right fruit, cutting it correctly, and managing your grill heat.
 
Here’s how to grill a watermelon the right way.
 

1. Choose a Firm, Ripe Watermelon

The best watermelon for grilling is ripe but still firm.
 
A watermelon that’s too soft will fall apart on the grates.
 
Look for one that feels heavy for its size and has a deep, hollow sound when you tap it.
 
You want a watermelon that holds its shape once it hits the heat.
 

2. Cut Thick, Even Slices

Slice your watermelon into rounds about one inch thick.
 
You can cut them into half-moons or quarters if the rounds are too big for your grill.
 
Just keep the slices thick and uniform so they cook evenly.
 
If you’re wondering how to grill a watermelon without it falling through the grates, thick slices are your answer.
 

3. Pat the Slices Dry

Watermelon is mostly water, so blot the cut sides with paper towels before grilling.
 
Less surface moisture means better char marks and less steaming.
 
This one small step makes a big difference in how your grilled watermelon turns out.
 

4. Preheat Your Grill to Medium-High

You want your grill hot but not screaming hot.
 
Medium-high heat, around 400°F to 450°F, is ideal for grilling a watermelon.
 
Clean the grates and brush them with a little oil so the slices don’t stick.
 

5. Grill for 2 to 3 Minutes Per Side

Place the slices directly on the grates and leave them alone.
 
After two to three minutes, flip them once and grill the other side.
 
You’re looking for visible grill marks and a slightly softened texture.
 
That’s really all there is to how to grill a watermelon.
 

Best Ways to Season Grilled Watermelon

Plain grilled watermelon is delicious, but a little seasoning takes it to another level.
 
Here are some of the best ways to flavor it.
 

1. Sea Salt and Lime

A pinch of flaky sea salt and a squeeze of fresh lime brightens up the smoky sweetness.
 
This combo is simple and lets the natural flavor of the grilled watermelon shine.
 

2. Honey and Chili Powder

Brush the slices with honey before grilling and sprinkle chili powder after.
 
The sweet-heat contrast is absolutely addictive.
 

3. Balsamic Glaze and Mint

Drizzle balsamic glaze over the warm slices and top with fresh mint.
 
It looks fancy but takes seconds to put together.
 

4. Tajín or Chili-Lime Seasoning

If you love Mexican street corn, you’ll love grilled watermelon with Tajín.
 
The tangy, spicy seasoning pairs beautifully with the caramelized fruit.
 

Tasty Ways to Serve Grilled Watermelon
