Ingredients

  • large red prawns, fresh and whole (about 4 per person)16 ud
  • garlic cloves, thinly sliced4 dientes
  • dried chilli (cayenne), split in two1 ud
  • extra-virgin olive oil from the Valencia region4 cda
  • flaky sea salt, Maldon-style (to finish)1 pizca
  • fresh parsley, chopped2 cda
  • lemon in wedges (to serve)1 ud

Method

  1. 01

    Light and open wide

    Light a generous bed of charcoal with no deflector. Open the bottom damper 80% and the top vent fully to bring the kamado to 280°C direct. Set the cast-iron plancha on the grate for the last 8-10 minutes so it reaches searing heat: a drop of water should vanish on contact.

  2. 02

    Prep the prawns (don't peel)

    Don't peel the prawns: the whole shell protects the flesh from the fierce heat and keeps the juices in. Pat them dry —surface water cools the plancha and steams them— and brush with a very thin film of olive oil. If the long antennae bother you, trim them with scissors, but leave the head and shell on.

  3. 03

    Onto the plancha, first side

    Lay the prawns on the glowing plancha without crowding them. You'll hear the sizzle immediately. Leave them 2 minutes untouched: the shell turns deep orange and a crust forms. Don't move them early —fidgeting breaks the sear and they leak water.

  4. 04

    Flip once only

    With curved tongs flip each prawn a single time and give it another 2 minutes on the second side. The flesh is done when it turns from translucent to opaque white and the tail curls slightly. Total time should not exceed 6 minutes: red prawns cook very fast and one extra minute dries them out.

  5. 05

    Garlic and chilli in the juices

    In the last minute, drop the sliced garlic and chilli to one side of the plancha, over the orange juice the heads have released. Pour in the rest of the olive oil. The garlic should turn golden, not burn —dark brown means bitter. Roll the prawns through that aromatic oil just before pulling them.

  6. 06

    Plate and finish

    Move the prawns to a warm dish and tip over the garlic, chilli and all the oil with the head juices. Flaky salt, fresh chopped parsley and a lemon wedge alongside. Serve at once, no resting: prawns are eaten straight away, the moment you can pick them up by hand.

About this recipe

Red prawns are short-fire shellfish: no indirect heat, no probes, no patience required. You want the kamado at 280°C direct, a cast-iron plancha properly hot and a mental six-minute timer. What makes this dish special is not the technique —it could not be simpler— but respect for timing: an overcooked prawn turns rubbery and loses all its charm. You nail it the moment you accept that the prawn is done sooner than you think.

Why fierce direct heat and nothing else

The red prawn (Aristaeomorpha foliacea or Aristeus antennatus, whichever is fresh at the market) is a small piece, fatty in the head and delicate in the tail. Over gentle heat it steams in its own juices and ends up bland; over fierce, fast heat the shell protects the flesh while it caramelises outside. That is why a flat-out kamado, bottom damper open 80% and top vent wide, is the perfect ally: the ceramic's thermal mass holds 280°C even when you lift the lid to flip. No deflector. No indirect zone. The prawn wants live fire and direct contact.

Cast-iron plancha versus the grate: the plancha wins

I have a firm opinion here after many summers in Torrevieja: for red prawns I prefer a cast-iron plancha to the open grate. The plancha holds the juice the heads release —that orange coral that is half the dish— and lets the garlic and chilli brown in that same juice instead of dripping onto the coals. The grate gives prettier bar marks but you lose the liquor. If a grate is all you have, run it flat out anyway and save the heads to suck on the side. The plancha wins on juiciness and on making the most of the prawn, which with expensive shellfish is no small thing.

The Mediterranean touch: garlic, chilli and olive oil

No long marinades, no sauces that smother. A good market red prawn tastes of the sea and that is exactly what you want to lift. Thinly sliced garlic browned in the oil, a split dried chilli, extra-virgin olive oil from the Valencia region (a local picual or arbequina more than does the job) and flaky salt at the end. A scatter of fresh chopped parsley off the heat and a wedge of lemon alongside. That is it. Everything else is clutter and competes with the product.

In 30 seconds

Kamado direct at 280°C, no deflector, cast-iron plancha glowing. Dry the prawns, a thread of olive oil. 2 minutes per side, flip once only. Drop the sliced garlic and chilli into the head juices in the last minute. Six minutes total, not one more: overcooked means rubbery. Do not peel before grilling —the shell protects the flesh. Suck the heads: the coral lives there, the best of the prawn. Finish with flaky salt, parsley and lemon.

Editor's tips

  • Freshness above all: buy the prawns the same day from the dock or a trusted fishmonger and get them to the kamado without dodgy thaws. The body should be firm, the head firmly attached and it should smell of clean sea, never of ammonia. With shellfish, the raw material is 90% of the dish.
  • Don't crowd the plancha. Pile too many prawns together and the temperature drops, they release water and steam instead of searing. Two quick batches beat one overloaded round: cast iron recovers its heat in seconds between batches.
  • Keep barbecue gloves handy. At 280°C direct, shifting the plancha or leaning in to flip is playing with literal fire. Heat-resistant gloves give you room to position the iron and work the tongs without rushing or burns.

FAQ

  • At what temperature and for how long do you grill red prawns?

    Fierce direct heat, around 280°C, no deflector. Total time is about 6 minutes: 2 minutes per side, flipping once, plus the last minute with the garlic and chilli. The signal they're ready is the prawn, not the clock: the flesh goes from translucent to opaque white and the tail curls slightly. Past 6 minutes it starts to dry out and turn rubbery. With small shellfish, slightly under is always better than over.

  • Cast-iron plancha or open grate for red prawns?

    For red prawns I go with the cast-iron plancha. It holds the orange head juices —half the flavour— and lets you brown garlic and chilli in that same juice instead of losing it through the coals. The open grate gives prettier marks and a smoky note, but the liquor escapes. If a grate is all you have, run it flat out anyway and save the heads to suck on the side. The plancha wins on juiciness and on wasting nothing.

  • Should you peel or clean the prawn before grilling?

    Don't peel before cooking. The whole shell is a shield: it protects the flesh from the fierce heat, holds moisture and concentrates flavour. Peeling first guarantees a dry prawn. You don't need to devein small, fresh prawns either, though if it bothers you a shallow cut along the back with scissors does the job. Do pat the surface dry before the plancha: excess water cools the iron and steams the shellfish instead of searing it.

  • How do I keep the shellfish from going dry or rubbery?

    The only real enemy of a prawn is overcooking. Three rules: don't peel first (the shell protects), don't exceed 6 minutes total, and flip only once. Watch the flesh, not the clock —the moment it goes from translucent to opaque white, it's done. Fierce, fast heat is your ally, not your enemy: it sears outside while the inside stays juicy. And don't let them sit on a cold platter: kamado to table, straight.

  • Which heads to suck and how to make the most of the prawn juices?

    Sucking a red prawn's head isn't bad manners, it's compulsory: that's where the orange coral and fatty juice live, the tastiest part of the prawn. Press the head to your mouth and slurp. To lose nothing, cook on the plancha and tip all the juice left behind back over the prawns at the end. That orange oil with garlic and coral is liquid gold: dunk bread in it, use it for a rice the next day, or reduce it into an express sauce. Throwing away a red prawn's heads is a culinary sin.
