Tandoori Prawns — Indian Seafood Clay Oven Style

This tandoori prawns recipe works on a simple principle most home cooks get backwards: prawns need almost no marinating time and even less cooking time, and treating them like chicken or lamb is the fastest way to end up with something rubbery. A short, punchy marinade and a two-to-three-minute char over high heat is really all this dish needs.

This guide covers prawn sizing and why it matters more here than in most seafood recipes, how deveining affects both texture and presentation, and the narrow cook window that separates plump, juicy results — whether you call this a tandoori prawns recipe or a tandoori shrimp recipe, the same rule applies. If you've had disappointing tandoori prawns before, timing was almost certainly the reason.

What You'll Need

A short list for a short cook — nothing here needs more than twenty minutes of contact time.

For the Prawns

• 1 lb jumbo prawns, 16–20 count, peeled and deveined, tails left on
• 1 tablespoon fresh lemon juice
• ½ teaspoon salt

For the Marinade

• ⅓ cup thick or hung yogurt
• 1 tablespoon ginger-garlic paste
• 1 tablespoon Kashmiri red chilli powder
• 1 teaspoon garam masala
• 1 tablespoon mustard oil
• 1 teaspoon ajwain (carom seeds)

For Finishing

• 1 tablespoon melted butter, for basting
• Lemon wedges and mint chutney, to serve

A note on sizing: 16–20 count means 16 to 20 prawns per pound — the size this recipe is built around. Smaller prawns cook even faster and are easy to overshoot past done, so if that's what you have, watch the clock even more closely than the timing below suggests.

Accessories and Oven Used In This Recipe

This tandoori prawns recipe was developed on the oven below, alongside accessories that solve specific problems in the steps that follow — starting with a proper gas connection if you're running this clay oven prawns setup on a commercial scale for repeated batches.

The Clay Tandoor Oven CU04 is an outdoor charcoal and wood-fired model — since it doesn't run on gas, it doesn't require the CSA/NSF gas certification our indoor commercial ovens carry, and financing is still available at checkout.

Choosing Your Prawns

Size affects this tandoori shrimp recipe more than almost any variable other than cook time itself, since smaller prawns need meaningfully less time on the wall than larger ones.

Jumbo (16–20 Count) — Recommended

Large enough to stay juicy through a fast char without overcooking in the time it takes to get proper colour. This is the default assumed by the recipe quantities above.

Extra-Jumbo or Colossal (Under 15 Count)

Workable and slightly more forgiving on timing, though a minute or so longer on the wall may be needed to cook all the way through.

Smaller Prawns (21–30 Count or Below)

These cook in well under two minutes and are easy to overshoot past done. If this is what's available, reduce the cook time and watch closely rather than following the timing above exactly.

Step by Step

Why Prawns Have the Narrowest Cook Window in This Collection

Prawns cook faster and less forgivingly than almost anything else covered across this recipe collection, and understanding why explains most of this recipe's rules.

Why Prawns Overcook So Quickly

Prawn muscle is made of very short fibres with minimal connective tissue holding them together, which means the proteins firm up and expel moisture almost immediately once heat is applied — there's no long, slow breakdown of tough connective tissue the way there is with a cut like lamb shoulder. That's why the difference between perfectly cooked and rubbery prawns is measured in tens of seconds, not minutes.

Why Marinating Time Is So Short

Prawns have almost no muscle fibre structure for a marinade to work into over time, so — much like paneer elsewhere in this collection — extended marinating doesn't improve texture. It just exposes the prawns to acid and salt for longer than needed, which can start to firm and toughen them before they ever reach the wall.

Why High Heat Matters Even More Here

Because the total cook time is so short, the wall needs to be hot enough to develop real char in that narrow window — a cooler wall means the prawns finish cooking through before any meaningful colour develops, similar to the general radiant-heat principle behind tandoori cooking broadly, just with far less room for error given how fast prawns cook.

What to Serve Tandoori Prawns With

This clay oven prawns dish works well as a quick starter or as part of a larger seafood spread alongside grilled tandoori fish. A simple squeeze of lemon and a mint-coriander chutney are usually all they need — the marinade already carries most of the flavour, and a heavier sauce would compete rather than complement.

These also work well threaded through warm naan with a little chutney and sliced onion, turned into a quick wrap for a lighter lunch option.

Additional Technique Notes

Set a Timer

This clay oven prawns dish overcooks faster than almost anything else in this collection. A kitchen timer removes the guesswork that visual doneness cues alone can miss.

Don't Over-Marinate

15 to 20 minutes is enough. Longer exposure to salt and acid can start to toughen the prawns before they ever reach the wall.

Pierce Through the Thickest Part

Skewering through the thickest part of each prawn keeps it curled evenly and prevents it from spinning loosely when turned.

Pat Thoroughly Dry First

Excess surface moisture dilutes the marinade and can steam the prawns instead of charring them on contact with the hot wall.

Pull the Moment They're Opaque

Residual heat continues cooking prawns briefly after they're off direct heat, so pull them just as they turn opaque rather than waiting for a fully cooked-through look on the skewer.

Common Problems and Fixes

The Prawns Came Out Rubbery

Almost always overcooking, even by less than a minute. Set a timer next time and pull them the moment they turn opaque.

The Prawns Spun on the Skewer

Piercing too close to the head or tail rather than through the thickest part. Re-thread through the centre of each prawn for a stable curl.

No Char Developed in the Short Cook Time

The wall likely hadn't reached 700°F or higher. Confirm with a thermometer gun — this recipe's window is too short to compensate for a cooler wall.

The Marinade Tasted Bland

Check that the prawns were patted dry before marinating — excess surface moisture dilutes the marinade's concentration on contact.

Storing Leftover Tandoori Prawns

This clay oven prawns dish keeps in an airtight container for up to 2 days refrigerated. Reheat very briefly — 30 to 45 seconds in a hot pan — since prawns toughen quickly on reheating, more so than almost any other protein in this collection.

These don't freeze well once cooked; the texture turns notably rubbery on thawing. If you want a make-ahead option, marinate raw prawns and freeze them uncooked instead, thawing fully before cooking.

Where Tandoori Prawns Fits

Tandoori prawns belong to the same coastal Indian seafood tradition as grilled tandoori fish, adapted from the broader tandoori marinade-and-char method to suit a much smaller, faster-cooking ingredient.

Tandoori Prawns Coastal North India	Quick yogurt-spice marinade, skewered, charcoal-charred in minutes — the style this recipe follows.
Chilli Garlic Prawns Indo-Chinese	Pan-fried in a soy-based sauce rather than marinated and wall-cooked, closer to a stir-fry than a tandoori dish.
Goan Prawn Balchão Goa	Simmered in a tangy, vinegar-forward pickled sauce rather than grilled — a curry, not a char-based preparation.
Malabar Prawn Curry Kerala	Coconut milk based and simmered slowly, built around an entirely different cooking method from this dry, fast-charred style.

A General Note on Nutrition

Prawns are one of the leanest proteins in this entire recipe collection — naturally low in fat and calories relative to their protein content, with this cooking method adding almost nothing beyond a light butter baste.

Prawns are naturally high in protein and carry a meaningful amount of cholesterol relative to their size, worth noting for anyone monitoring that closely. As with any recipe, check ingredients against your own dietary needs via USDA FoodData Central rather than relying on general notes like this one.
