Barbecued shell-on prawns in garlic butter with parsley and lemon wedges on a white plate

Shell-on prawns cook fast and hard on the barbecue, and the shell does a lot of the work for you: it protects the flesh from the direct heat so the prawn stays juicy while the outside gets a bit of char. Peeling your own prawn at the table, fingers slick with garlic butter, is part of the point.

The main thing that goes wrong with barbecue prawns is overcooking. They need two or three minutes a side over high heat, no more. Pull them off as soon as the shells turn pink-orange and the flesh is opaque. They'll keep cooking a little from residual heat once they're off the grill.

Melt the garlic butter separately rather than brushing the prawns with it before they go on. Butter on the grill plate burns and turns bitter at the heat you need for prawns. Instead, toss the cooked prawns through the warm butter in a bowl or pan off the heat, which coats them without scorching anything.

Serve them straight from the bowl with lots of napkins, crusty bread for the butter left in the bottom, and lemon wedges on the side. A cold beer or a glass of something crisp is the only other thing this needs.

Method

  1. Step 1: To devein prawns yourself, run a skewer along the back through the shell and pull out the dark vein. Pat the prawns dry and toss with the olive oil and salt.

  2. Step 2: Heat the barbecue flat plate or a grill pan to high. Cook the prawns for 2-3 minutes on the first side, until the shell turns pink-orange, then flip and cook another 1-2 minutes until the flesh is opaque all the way through.

    Tip: Cook in batches if your plate isn't big enough to fit them all flat. Crowding the prawns means they steam instead of char.

  3. Step 3: While the prawns cook, melt the butter in a small saucepan over low heat. Add the garlic and chilli and cook gently for 1 minute, just until fragrant, then take off the heat and stir in the lemon juice.

  4. Step 4: Tip the hot prawns into a large bowl, pour over the garlic butter and toss to coat. Scatter with parsley and serve immediately with bread and lemon wedges.

Tips

  • Buy prawns a size up from what you'd normally use for a stir-fry. Smaller prawns overcook in the time it takes the shell to colour.
  • A squeeze of lemon into the butter right at the end stops it tasting flat, add it off the heat so it doesn't split the butter.
  • If your barbecue runs hot and uneven, move the prawns to a cooler spot on the plate once they've coloured, rather than leaving them on the hottest part the whole time.

Variations

  • No barbecue: cook in a hot grill pan or frying pan on the stove using the same method and times.
  • Skewer them: thread the prawns onto metal or soaked wooden skewers before cooking if you want to turn a whole batch at once.
  • Herb swap: use coriander instead of parsley and add a splash of fish sauce to the butter for an Asian-leaning version.

Storage and make-ahead

Best eaten hot, straight off the barbecue. Leftover prawns keep in the fridge for a day and are good cold in a sandwich or salad, but the garlic butter won't taste the same reheated.
