Italian Spaghetti with Red Prawns, Cherry Tomatoes and Basil | Spaghetti con Gamberi Rossi, Pomodorini e Basilico
Updated: 2 days ago
This is the pasta of the Sicilian channel, the water between Mazara del Vallo and the coast of Africa where the gambero rosso is trawled from deep cold ground. The prawn is the whole point: sweet, almost sugary, with flesh so soft that a minute of real cooking ruins it, and a head full of dark coral that carries more flavour than the tail ever will.
The sauce is therefore built in two stages that never meet the tails at high heat. The heads and shells are pressed into a fast concentrated extraction, ten minutes at most, which becomes the savoury backbone. Datterino tomatoes are then split open just long enough to release their juice. The tails go in at the very end, off the flame.
What reaches the plate is not a tomato pasta with prawns in it, but a prawn pasta that a little tomato has been used to brighten. The basil goes in torn and late, the oil is raw at the finish, and there is no cream, no butter and no cheese. Dairy flattens the marine sweetness the whole plate is organised around.
Yield: 4 servings. Prep: 30 minutes. Cook: 25 minutes. Total: about 55 minutes. Difficulty: intermediate. Course: primo piatto. Region: Sicily, the western coast and the Trapani province.
The Story
The gambero rosso di Mazara del Vallo is why this dish exists in the form it does. Mazara sits on the southwestern corner of Sicily, closer to Tunisia than to Palermo, and its deep water fleet is the largest in Italy. The boats work grounds between 400 and 700 metres down, and the prawns they bring up carry an intensity of flavour that shallow water species never develop.
The tomato arrived late and has stayed a minor character. Sicily grows the datterino and the pomodorino di Pachino on the sun baked southeast corner of the island, and both are prized for sugar rather than acidity. Cooks on the western coast borrowed them because they add sweetness and colour without the sourness a plum tomato would bring. A long cooked sauce would bury the prawn.
Basil is the third element, and its use here is specific: it is never cooked. In the trattorie of Marsala and Trapani the leaves are torn over the pan after the flame is out, so the volatile oils survive and the aroma arrives before the first forkful. Almost nothing in this recipe is cooked for as long as an inexperienced cook expects, and almost everything is better for it.

Preparation
Clean the prawns and keep every part
Twist the heads away from the tails, catching any coral or juice that runs out. Peel the tails and reserve the shells with the heads. Run a small knife down the back of each tail and lift out the dark intestinal tract. Cut four of the largest tails lengthwise in half so they curl attractively later. Cover them and keep them in the coldest part of the refrigerator until the final minute: red prawns deteriorate faster than any other shellfish.
Build the prawn extraction
Heat the 2 tablespoons of oil in a small saucepan over medium high heat, add the crushed garlic and the heads and shells, and press the heads firmly with the back of a wooden spoon so the coral is released into the oil. Cook 3 to 4 minutes until the shells turn deep orange and the kitchen smells of roasted shellfish. Add the wine, let it evaporate, then add the hot water and a pinch of salt and simmer 8 to 10 minutes, no longer: shells held too long turn bitter.
Strain and reduce the extraction
Pass the liquid through a fine mesh sieve, pressing the solids with a ladle to force through every drop of coral, then discard the shells. You should have about 3/4 cup (180 ml) of opaque orange liquid. Return it to the pan and reduce gently to about 1/2 cup (120 ml), until it tastes clearly of prawn rather than of water. Keep it warm. This small quantity is the entire savoury structure of the dish.
Prepare the tomatoes
Cut the cherry tomatoes in half through the equator rather than pole to pole, which opens the seed chambers and lets them release juice faster. Leave about a quarter whole so there is a burst of intact tomato on the plate. Do not peel or seed them: the skins hold the shape together and the seed gel carries most of the free glutamate.
Set the pasta water
Bring the 5 quarts of water to a rolling boil in a tall pot and add the coarse salt only once it is boiling. The sauce carries almost no salt of its own and relies on the pasta absorbing seasoning as it cooks, so taste the water: it should be close to seawater. Slide in the spaghetti, stir in the first 30 seconds, and set a timer for 2 minutes less than the packet time.
Start the sauce
While the pasta cooks, heat the 3 tablespoons of oil in a wide saute pan over medium heat with the sliced garlic and the crumbled peperoncino. Let the garlic go pale gold and no further. The moment it colours, add the tomatoes and the salt, raise the heat and cook 3 to 4 minutes, pressing a few halves so they collapse while the rest stay whole. Add the wine, let it evaporate, then pour in the warm extraction.
Finish the pasta in the pan
Lift the spaghetti out with tongs 2 minutes before it is done and drop it into the sauce with the water clinging to it. Add a ladle of cooking water and cook over high heat for those last 2 minutes, tossing continuously and adding more water a little at a time so the pan stays loose. You are forcing the spaghetti to give up its surface starch into the extraction, which turns a thin orange liquid into a glossy sauce that clings. Stop at al dente.
Add the prawns off the heat
Take the pan off the flame completely. Scatter the raw tails over the pasta, add the raw olive oil and the torn basil, and toss hard for 20 to 30 seconds. The residual heat turns the tails from translucent to barely opaque, which is exactly where a red prawn should be: still soft and slightly yielding at the centre. Put them in while the pan is on the heat and they tighten and lose their sweetness. Finish with lemon zest and pepper and serve at once.
Plating
Warm the bowls, and warm them properly. A wide shallow bowl at around 140°F (60°C) keeps the emulsion fluid for the two or three minutes the plate takes to eat, while a cold bowl seizes the starch and the sauce breaks into oil and water. Warm them under hot water, dry them, and line them up before the pasta leaves the pan.
Use long tongs or a carving fork to lift a portion and twist it into a nest as you lower it into the bowl. Height matters more than width: a compact twist holds its heat, while a flat spread goes cold. Spoon the sauce and the tomatoes left in the pan around the base of the nest rather than over the top, so the strands stay visible and glossy.
Arrange the tails on and around the nest, using the halved ones to show the pale flesh and the line of coral. Tuck two or three basil leaves where they will be seen, add a final thread of raw oil and send the plate out. The service window is about ninety seconds before the sauce tightens.
Professional Technique
The governing technique is the separation of one animal into two ingredients cooked at opposite temperatures. The heads and shells want aggressive heat: the coral holds carotenoid pigments and fat soluble aromatics that transfer into olive oil only when pressed and fried, and a simmered head gives up a fraction of what a crushed one does. The tails want almost no heat at all. Prawn muscle proteins begin to contract around 122°F (50°C), and a deep water red prawn passes from perfect to rubbery inside about forty seconds.
The second technique is reducing the extraction to a measured volume rather than to a vague thickness. Half a cup of concentrated prawn liquid seasons 12 ounces of spaghetti and no more. Too much and the starch the pasta releases cannot bind it, so the sauce slides off the strands. Too little and the pan runs dry during the final toss and the starch scorches on the base.
The third is cooking the tomatoes for minutes rather than half an hour. A long cooked tomato develops jammy, almost caramelised notes that read as pizza sauce and dominate everything beside them. A cherry tomato split open in hot oil for three minutes gives up its juice and its glutamate while keeping its raw perfume and acidity, which stops the prawn tasting flat.
Texture and Moisture Control
Everything depends on starch, and the starch has to come from the right place. Bronze die spaghetti has a rough chalky surface that sheds far more amylose than smooth industrial pasta does, and that amylose is what turns the extraction into a coating sauce. This is why the pasta is transferred wet with tongs rather than drained, and why the cooking water goes in a ladle at a time. Never rinse the pasta and never oil the boiling water.
Moisture in the pan is managed by adding and evaporating, not by guessing. During the final toss the sauce should look slightly looser than you want it on the plate, because the pasta keeps absorbing liquid for a full minute after it stops cooking. If the pan tightens, a tablespoon of cooking water restores it instantly. The movement matters as much as the heat: shaking keeps oil and water in suspension, and a pan left still will separate.
The al dente point is a structural requirement here, not a preference. The spaghetti leaves the water 2 minutes early, still distinctly firm, because it completes its cooking in the sauce while absorbing flavour instead of plain water. Pasta cooked fully in the pot can only overcook from there. The tails, meanwhile, have no margin at all: translucent to just opaque is the entire range.

The last four minutes leave no time for anything except tossing the pan, so everything is ready and within reach before the spaghetti goes into the water.

Chef Tips
Buy the prawns whole, with the heads firmly attached. A loose head, or a joint that has gone black, means the prawn has been sitting, and since the head is the flavour engine here a tired one costs you the sauce. Prawns frozen at sea are usually better than a fresh prawn that travelled three days.
Press the heads, do not simply simmer them. The difference between a pale broth and a deep orange extraction is thirty seconds of firm work with the back of a spoon while the shells are in hot oil. Everything worth having is inside the head.
Keep a mug of pasta water beside the pan until the plates have gone out. It is the only correction tool you have: it loosens a sauce that has tightened and rescues an emulsion starting to separate. Pouring the pot down the sink before you have plated cannot be undone.
If you cannot find red prawns, use the best whole head on prawn available and adjust the timing rather than the method. A warm water white prawn is firmer and wants 45 seconds in the pan rather than residual heat alone. It is very good, but it is not the Mazara dish.
Common Mistakes
Cooking the prawn tails with the sauce. This ruins the dish more often than every other error combined. Red prawn flesh passes from silky to rubbery in under a minute over direct heat, and contracted proteins never relax. Take the pan off the flame first.
Throwing the heads and shells away. Roughly two thirds of the flavour of a red prawn sits in the head and its coral. A version built on peeled tails alone tastes thin and needs stock, cream or cheese to compensate.
Cooking the tomatoes into a sauce. Twenty minutes in the pan turns cherry tomatoes sweet, jammy and dominant, and the prawn disappears underneath them. Three to four minutes is the whole window: they should release juice and still hold their shape.
Draining the pasta in a colander. Draining loses the surface starch and the clinging water the emulsion depends on, and the pasta cools and sets before it reaches the pan. Lift the spaghetti out wet with tongs.
Adding cheese. Parmigiano or pecorino on a delicate shellfish pasta coats the palate with milk fat and salt and flattens the marine sweetness. No regional version of this dish uses it.
Wine Pairing
Grillo Sicilia DOC: The local answer and the most natural one. Grown across western Sicily within sight of the boats that land these prawns, it carries ripe citrus and a distinctly saline finish that echoes the marine sweetness of the tails. There is body enough for the raw oil and acidity enough to keep the tomato bright.
Etna Bianco DOC: Carricante grown on volcanic soil at altitude, and the most structured white here. Its high, almost austere acidity and the stony thread running through it cut cleanly across the concentrated extraction, while a faint smoky note picks up the roasted character the shells develop in the pan. Serve it at 50°F (10°C).
Vermentino di Gallura DOCG: From the granite hills of northern Sardinia, and a wine built for shellfish. The saline bite and the bitter almond finish sit alongside the prawn rather than over it. Where the Etna is tense and mineral, this is rounder and more perfumed, which suits a plate finished with torn basil.
Cerasuolo di Vittoria DOCG: The red option, from the southeast of Sicily where the tomatoes come from, and it works if you serve it cool at around 57°F (14°C). The Frappato brings red cherry fruit and very light tannin that finds the sweetness of the tomato, while the Nero d Avola gives just enough grip for the olive oil.
Storage & Reheating
This is a dish to cook and eat, not to keep. Dressed spaghetti keeps absorbing sauce as it sits, so within twenty minutes the strands have swollen and drunk the emulsion. If you have leftovers, refrigerate them airtight for up to 24 hours.
To reheat, never use a microwave and never add water directly to cold pasta in a pan. Warm a tablespoon of oil and two tablespoons of water in a saute pan over medium heat, add the pasta, cover and steam for about 90 seconds, then uncover, toss and serve. Picking the tails out first and returning them off the heat at the end saves their texture.
The components keep far better than the finished plate. The strained extraction keeps in a sealed jar for 2 days and freezes for up to 2 months, and an ice cube tray of it is a useful base for risotto or fish soup. Raw tails should be used the day they are cleaned. Cooked prawns do not freeze in any way worth eating.
