BBQ Prawns or Shrimp with Watermelon

As much as I love a good burger, these massive BBQ prawns or shrimp for readers around the world are the undisputed heavyweight champions of BBQ season. They need very little to help them on the way, just a little chili, lemon garlic and fire!

BBQ Prawns or Shrimp.

Both my wife and I were in great need of cheering up last weekend and as far as I am concerned that means great food. So we went and splurged on one of my favourite, if expensive, treats!

Now with ingredients this good there is not a lot you need to do.

In fact, the less you do the better the meal is! Just like my grilled trout recipe, these BBQ prawns rely on a few great ingredients.

Garlic, chili and lemon are all we add apart from salt and for me, that is all they need.

What Size Prawns are Good to Cook on the BBQ?

The simple answer is anything from around 25mm long and upwards.

This meal was a treat for us so I sprung for some 8-10 sized prawns much like these Harissa Garlic Prawns. But here I cooked them in their shells.

The aroma of cooking seafood in this way is one of my favourite smells.

Incidentally, the sizing of shrimp or prawn refers to the number per pound. As a result, the smaller the number the bigger the prawn.

But if you have something smaller then stick them on a skewer (see what I did there). This grilled shrimp recipe is a great example of this.

Watermelon on the BBQ?

‘But watermelon’ I hear you say, and I respond with a resounding YES!

The sweet tartness of the watermelon works amazingly with the texture and flavour of the shrimp.

You can go sweet with brown sugar or honey and serve it with ice cream, or go savoury and serve with seafood or pork.

I have a slightly different take on grilled watermelon in this glazed pork tenderloin recipe.

On that note I will leave you alone, you have shopping and cooking to do!

BBQ Prawns or Shrimp with Watermelon

Yield: 2 Servings
Prep Time: 10 minutes
Cook Time: 10 minutes
Total Time: 20 minutes

With ingredients this good it is best to keep things simple so a little Lemon, Chili and Garlic mixed with a bit of fire is all that is needed to make these BBQ Prawns or Shrimp Sing!


  • 400 g Prawns
  • 1 Thai Birds Eye Chili Pepper
  • 1 Garlic Clove
  • 1 Lemon
  • 2 Tbsp oil to coat
  • Salt and Pepper to taste
  • Rocket to serve
  • Oil for dressing

For the Watermelon

  • 1 Watermelon
  • 1 Tbsp Sweet Chili Sauce
  • 1 Tbsp Oil
  • Salt and Pepper to taste


  1. Finely chop the chili and garlic.
  2. Take a slice across the circumference of the water melon approximately 1.5 cm thick then slice that into 6 wedges.
  3. When your grill is ready to rock and roll, mix together the sweet chili sauce, oil for the water melon salt and pepper and use this to coat the water melon slices.
  4. Now onto the prawns, mix together the garlic, chili, salt & pepper and oil and coat the shrimp.
  5. Now we are ready to cook, you will need to work on your own judgement on a little, the watermelon takes 10 minutes to be just about perfect.
  6. These prawns take about 7 based on experience but the cooking time will entirely depend on their size, mine were 50g each, so around 8-10 count).
  7. Add the watermelon to the grill, followed by the shrimp, half way through cooking flip over.
  8. Just before serving and whilst still on the grill squeeze the juice of one lemon over the shrimp and serve with the melon.
  9. Finally dress the rocket with some nice oil and place on the side.


If using frozen shrimp defrost as quickly as you can, stick in a colander and allow cold water to run over them, they should defrost in 10-15 minutes, this helps maintain the texture of the meat.

  1. It’s been really hot here in the Netherlands the last few weeks and when ever that happens we fire up the bbq. I made your grilled shrimp with watermelon and rocket yesterday and it was fabulous. This one is a keeper. Thank you for the recipe!

  2. This is such a pretty dish for the summer. Pairing the watermelon with the shrimp is brilliant. I am so intrigued how you added the sweet chili sauce to the watermelon for grilling. I can’t wait to see what that will taste like.

  3. Oh, we love grilling here! All summer long, we grill! Easy clean up and great flavor! You can’t go wrong! These shrimp look amazing! In the states we have a hard time finding the shrimp with the head on. Ours now are what they call easy peel, they are deheaded, split and veins removed! I love the presentation with the heads! This recipe sounds great with the grilled watermelon! I must give it a try!

    • Most of our shrimp are like that too, which is sad… But on occasions we get big boys like this and the only thing to do is fire up the BBQ and go to town 😀

  4. Grilled watermelon sounds unbelievable! I have never even thought of grilling watermelon before but you have inspired me 🙂 I will be adding some watermelon to our next BBQ menu for sure!

  5. I used to only eat fried popcorn shrimp and wouldn’t eat it any other way but I’m falling in love with it cooked all different ways. I haven’t tried it on the grill yet, though so I’m adding this one to the list!

  6. Ooooh I need to try grilled watermelon! Perfect for summer. Good to see you posing some seafood, you know I love my shrimp. This looks awesome!

    • I love grilling watermelon, yup finally got my hands on some great seafood… Soooo expensive but we are worth it, right?

  7. I am so, so jealous of your gorgeous grill set up! Tell me again how I quit my job and move to the Hungarian countryside…?

    • Cheer Hillary, it’s been a while but it goes something like this, go to a music festival, get drunk, buy a house and figure ‘f’ it, in for a penny in for a pound 😉

  8. I love Grilled Shrimp Brian – it’s one of my very favorite ways to enjoy it! And pairing it with watermelon sounds delish!

  9. Wonderful, nothing more 🙂 Never tried the combination of shrimp with watermelon on the grill. Actually, I think that meals cooked in the fresh air will taste better 🙂

    • Totally with you on the alfresco cooking thing, I spent years not cooking outside after being forced to spend 9 months cooking outside… Feels great to be back at it again.

  10. I may be salivating right now:-) Love shrimps (or prawns as we call them in the UK, to us shrimps are those tiny wee things), just wishing we had the weather for a BBQ right now as summer seems to have bypassed us so far!

    • I’m British too so know them as prawns, but I must make concessions to the great Google gods… Most of my readers are US based and no one knows them as prawns 😉 I believe the British summer is coming three weeks on Tuesday, it will finish on Wednesday, you hear it here first 😀

  11. As a child and teenager, l used to stick to dishes l knew, was never adventurous enough to try new things, and shrimps were not on my list. l absolutely love them now, and l can’t believe l was so silly not to eat shrimps. This dish is my kind of perfect food when looking for a great treat, quick, delicious and posh. I know what you mean about paying more for quality food, the taste is so worth that extra money. I’ve never tried grilled water melon, but l can’t get enough of melons when they are in season, so l’ll have to give the grilled one a go.

    • I guess we were all like that when we were younger, I know I certainly was… The water melon works really well on a grill and with a bit of chili is a perfect partner for the Shrimp 🙂
