To make grilled watermelon, you slice a ripe watermelon into thick slabs, brush them with a little oil, and cook them on a hot grill until you get those beautiful char marks.
Yes, you read that right — grilled watermelon might sound strange at first, but once you try it, you’ll wonder why you didn’t fire up the grill sooner.
The heat transforms the fruit in a way that’s honestly kind of magical.
It brings out the natural sweetness, adds a subtle smoky flavor, and gives the texture a slightly firmer bite that works beautifully in both sweet and savory dishes.
In this post, we’ll cover exactly how to make grilled watermelon, the best ways to season it, and a few tasty topping ideas to take it to the next level.
Let’s get grilling.
How to Make Grilled Watermelon
Making grilled watermelon is easier than you might think, and you only need a handful of things to get started.
Here’s what you’ll need and how to do it step by step.
1. Pick the Right Watermelon
The first step in how to make grilled watermelon is choosing a ripe, firm watermelon.
You want one that’s heavy for its size and sounds slightly hollow when you tap it.
A good ripe watermelon will have a deep, even color and a creamy yellow spot on one side where it rested on the ground.
Avoid watermelons that feel soft or mushy because they won’t hold up well on the grill.
2. Slice It Into Thick Slabs
Cut your watermelon into slices that are about one inch thick.
You can go with wedges, rounds, or even large rectangular planks — whatever shape you like.
Just keep them thick enough so they don’t fall apart when you flip them.
If there are seeds, you can leave them in or remove them, but removing them makes eating a bit easier.
3. Brush With Oil
Lightly brush both sides of each watermelon slice with a neutral oil like avocado, canola, or grapeseed oil.
This helps prevent sticking and encourages those lovely grill marks.
You can also use a little melted coconut oil if you want a hint of sweetness.
4. Preheat Your Grill
Get your grill nice and hot — around medium-high heat works great.
Make sure the grates are clean and lightly oiled so your watermelon doesn’t stick.
If you’re using a grill pan indoors, heat it over medium-high heat until it’s smoking slightly.
5. Grill Each Side for 2–3 Minutes
Place the watermelon slices on the grill and let them cook for about two to three minutes per side.
You’re looking for clear grill marks and a slight softening of the flesh.
Don’t walk away — watermelon can go from perfectly charred to burnt quickly.
Once both sides are done, transfer the slices to a plate.
Best Ways to Season Grilled Watermelon
Now that you know how to make grilled watermelon, let’s talk about flavor.
The great thing about grilled watermelon is that it pairs well with so many different seasonings, from sweet to savory.
1. Sea Salt and Lime
A sprinkle of flaky sea salt and a squeeze of fresh lime juice is one of the simplest and most delicious ways to enjoy grilled watermelon.
The salt enhances the sweetness while the lime adds a bright, tangy kick.
2. Chili Powder and Honey
For a sweet-and-spicy combo, drizzle a little honey over your grilled watermelon and dust it with chili powder.
The heat from the chili pairs beautifully with the smoky char and natural sweetness of the fruit.
3. Fresh Herbs Like Mint or Basil
Chopped fresh mint or basil adds a refreshing twist that balances the smoky flavor.
Toss the herbs over the grilled slices right before serving for a pop of color and freshness.
4. Balsamic Glaze
A drizzle of balsamic glaze takes grilled watermelon to a whole new level.
The tangy, syrupy glaze complements the sweetness and adds a gourmet touch with almost no effort.
Delicious Topping and Serving Ideas
Once you’ve mastered how to make grilled watermelon, you can get creative with how you serve it.
Here are a few ideas to try.
1. Grilled Watermelon Salad
Toss grilled watermelon chunks with arugula, feta cheese, red onion, and a balsamic vinaigrette.
It’s a summer salad that’s sweet, salty, and smoky all at once.
2. Watermelon Skewers
Thread grilled watermelon cubes onto skewers with fresh mozzarella balls and basil leaves.
Drizzle with olive oil and balsamic for a fun, bite-sized appetizer.
3. Dessert Watermelon
Top grilled watermelon with vanilla ice cream, a drizzle of honey, and crushed pistachios.
It’s a dessert that feels fancy but comes together in minutes.
4. Watermelon and Feta Bites
Layer grilled watermelon slices with whipped feta and a sprinkle of mint.
These little bites are perfect for parties and always disappear fast.
5. Grilled Watermelon Tacos
Use grilled watermelon as a filling for tacos with black beans, avocado, and a squeeze of lime.
It’s a vegetarian twist that even meat lovers will enjoy.
