Spaghetti with Guanciale and Tomato | Spaghetti all'Amatriciana

Amatriciana is a sauce of five ingredients and no hiding places. Guanciale, tomato, Pecorino Romano, black pepper and a little chilli, cooked in under fifteen minutes and tossed with spaghetti that finishes its cooking in the pan. There is no onion in the version the town of Amatrice registered, no garlic, no olive oil beyond the film needed to start the pork, and no cream anywhere at any point. Every one of those absences is deliberate, and every one of them is regularly ignored outside Italy.

What makes the dish difficult is that it rewards timing rather than skill. The guanciale has to render slowly enough to give up its fat and then crisp without burning. The tomato has to cook only long enough to lose its raw edge. The Pecorino has to go in off the heat or it seizes into strings. And the pasta has to leave the water while it is still stubborn in the centre, because the last minute of cooking happens in the sauce, drinking the starchy water that turns fat and tomato into something glossy.

Yield: 4 servings. Prep: 15 minutes. Cook: 20 minutes. Total: about 35 minutes. Difficulty: intermediate. Course: primo piatto. Region: Lazio, the town of Amatrice and the Roman table.

The Story

Amatrice sits at about 3,000 feet in the mountains of northern Lazio, in a landscape of sheep pasture rather than vegetable gardens. The dish that carries its name began as gricia, the white version: cured pork jowl, sheep cheese, black pepper and pasta, the four things a shepherd could carry and keep. Tomato arrived late, and only in the late eighteenth or early nineteenth century did the red version settle into the form we cook now.

The route into Rome was human. Amatriciani worked the capital as butchers, innkeepers and cooks, and brought the sauce to the osterie of Testaccio and Trastevere, where it was adopted so completely that most Romans think of it as theirs. The town has defended the point. Amatrice holds its sagra every August, and in 2020 the dish received European protected status as Amatriciana Tradizionale, which fixed the ingredient list in law.

That list is short and it excludes things people expect. Guanciale, not pancetta and never bacon. Pecorino Romano, not Parmigiano. San Marzano or equivalent peeled tomatoes. Dry white wine, chilli, black pepper. No onion, no garlic, no parsley. After the 2016 earthquake that destroyed much of Amatrice, restaurants around the world put the dish on their menus as a fundraiser, and for a season it became the most cooked pasta in Italy.

Ingredients

For the pasta

• Spaghetti, bronze die, 14 oz (400 g)

• Water, 5 quarts (4.7 liters)

• Coarse sea salt, 1 1/2 tbsp (25 g)

For the sauce

• Guanciale, in one piece, rind removed, 7 oz (200 g)

• Dry white wine, 1/4 cup (60 ml)

• Peeled San Marzano tomatoes, 14 oz (400 g), crushed by hand

• Dried peperoncino, whole, 1, or crushed red pepper flakes, 1/2 tsp (1 g)

• Freshly cracked black pepper, 1/2 tsp (1.5 g)

• Fine sea salt, to taste

For finishing

• Pecorino Romano DOP, finely grated, 2 1/2 oz (70 g)

• Reserved pasta cooking water, about 1/2 cup (120 ml)

• Freshly cracked black pepper, to taste

Preparation

Step 1

Cut the guanciale correctly. Take the rind off and keep it for a bean soup. Cut the meat into strips about 1/4 inch (6 mm) thick and roughly 1 1/4 inches (3 cm) long. Thin slices dry out and turn to leather, and large cubes stay raw in the middle while the outside burns. Keep the strips cold until the pan is ready.

Step 2

Render the fat, do not fry it. Put the guanciale into a cold, wide, heavy pan with no oil at all and set it over medium low heat. The fat has to melt out slowly, which takes 7 to 9 minutes, and the strips will shrink, turn translucent and then colour at the edges. If the pan spits and the pork browns within two minutes, the heat is far too high and the fat that should coat the pasta is still locked inside the meat.

Step 3

Take the guanciale out and deglaze. When the strips are golden and crisp at the edges but still give slightly in the centre, lift them out with a slotted spoon onto a plate and leave the rendered fat behind. Removing them now is what keeps them crisp, since anything left in the tomato softens back into chewiness. Add the peperoncino and cracked black pepper to the hot fat for a few seconds, then pour in the white wine, raise the heat and scrape the base of the pan while it bubbles. Reduce until only a syrupy film remains, about a minute.

Step 4

Cook the tomato briefly. Crush the peeled tomatoes with your hands directly into the pan, which gives a rougher and better texture than any blender, and add no water. Simmer over medium heat for 8 to 10 minutes until the sauce has darkened, the fat has begun to separate at the edges and a spoon drawn through it leaves a track that closes slowly. Taste before adding salt: guanciale and Pecorino are both salty and the sauce usually needs none.

Step 5

Salt the water and cook the spaghetti. Bring 5 quarts (4.7 liters) of water to a rolling boil and add 1 1/2 tablespoons (25 g) of coarse salt. That ratio, around 5 grams per liter, seasons the pasta from the inside without making the water too salty to use in the sauce. Add the spaghetti, stir for the first thirty seconds so the strands do not weld, and cook it for 2 minutes less than the packet time.

Step 6

Reserve the water and transfer. A minute before draining, dip a mug into the pot and take out roughly 1 cup (240 ml) of the cloudy water. Tap water will not do the same job, because what you need is the dissolved starch. Lift the spaghetti straight from the pot into the tomato pan with tongs, rather than draining it in a colander where it loses both heat and starch.

Step 7

Finish the pasta in the pan. Raise the heat to medium, add a ladle of the reserved water and toss constantly for 2 minutes. The spaghetti will drink the liquid and release starch, and what looked thin will tighten into a glossy coat. Add more water a little at a time if it dries out. Return most of the guanciale in the final thirty seconds so it warms through without softening.

Step 8

Add the Pecorino off the heat. Take the pan off the burner, wait about fifteen seconds, then add most of the grated Pecorino Romano in two additions, tossing hard between them. The cheese must not meet direct heat or its proteins tighten into rubbery threads sitting in an oily sauce. If the pasta seizes, a tablespoon of hot pasta water and vigorous tossing brings it back. Serve immediately.

Plating

Amatriciana is served hot and without ceremony, but the vessel matters. Use a warmed shallow bowl rather than a flat plate, because the sauce is thin enough to run and a rim keeps it against the pasta. Warm the bowls with hot water and dry them just before serving: a cold bowl drops the temperature on contact and the fat begins to set.

Twist a portion around a carving fork or a pair of tongs and lower it into the bowl as a nest rather than dropping it flat, then spoon any sauce left in the pan over the top. Scatter the reserved crisp guanciale over each serving so it stays on the surface and keeps its texture, finish with the last of the Pecorino and a fresh grind of black pepper. No parsley, no basil, no olive oil at the table.

Professional Technique

The technique that defines this plate is the emulsion between rendered pork fat, tomato and starchy water, built in the pan during the final two minutes. Fat and water do not mix on their own; what holds them together is the starch leaching out of the spaghetti as it finishes cooking, which acts as a stabiliser and traps droplets of fat in suspension. Agitation supplies the mechanical energy, so the tossing has to be constant and reasonably violent, not a gentle stir.

The second is the split treatment of the guanciale, rendered then removed then returned. Most of what the pork contributes is fat and it needs to be in the sauce, but the crisp texture of the meat survives only if the strips stay out of the wet phase. Starting from a cold pan matters for the same reason a confit starts cold: fat that liquefies gradually carries flavour out with it, while fat hit by high heat seals the surface and stays where it is.

The third is temperature discipline with the Pecorino Romano. Sheep milk cheese has a firm protein network and a low melting tolerance, and above roughly 160°F (70°C) the casein contracts and squeezes out fat, which is the stringy, greasy result people get when they tip cheese into a boiling pan. Off the heat, with a pause and plenty of movement, the same cheese dissolves into the emulsion and thickens it.

Texture and Moisture Control

Three textures have to arrive together: spaghetti firm at the core, sauce glossy and clinging, guanciale crisp. The pasta is the easiest to lose. Draining at the packet time and then giving it two minutes in the pan cooks it well past al dente, so the early exit is arithmetic, not style. A thin pale line should still be visible in the middle of a bitten strand when it leaves the water.

Moisture in the sauce is managed entirely with the reserved water, added in small amounts rather than all at once. A sauce that looks correct in the pan will tighten noticeably in the thirty seconds it takes to reach the table, so the pasta should leave the heat marginally looser than you want it. If it has turned claggy, another spoonful of hot water and ten seconds of tossing restores it. Cold water will not, because it drops the temperature and breaks the emulsion.

The crisp element is the most fragile. Guanciale returned to the pan too early absorbs tomato liquid and goes limp within a minute, which is why most of it goes back at the very end and the rest is scattered on top. Serve immediately: even a correct Amatriciana separates once the fat sets.

Professional Mise en Place

Everything is cut, measured and within reach before the pasta goes into the water. The final toss cannot wait.

Equipment and tools

• Wide heavy sauté pan, at least 12 inches (30 cm), able to hold all the pasta

• Large stockpot, 6 quart (6 liter) capacity or more

• Tongs or a carving fork for transferring the spaghetti straight from the pot

• Slotted spoon, heatproof mug for the pasta water, fine grater for the Pecorino

Prepared ahead

• Guanciale cut into strips, up to a day ahead, kept covered and cold

• Pecorino Romano grated fine on the day, kept covered so it does not dry out

• Tomatoes crushed by hand into a bowl and ready beside the stove

• Wine measured, peperoncino and cracked pepper in a small dish

Service setup

• Tomato sauce held warm and slightly loose over the lowest heat

• Crisp guanciale on a plate beside the stove, never in the sauce

• Pasta water at a rolling boil, salted, mug ready to draw from it

• Bowls warming in hot water, dried just before the pasta is plated

Chef Tips

Buy guanciale in a piece rather than presliced. Cured pork jowl has a very high ratio of fat to lean and the method depends on that fat rendering slowly, which cannot happen with machine cut slices. A good piece is firm, deep pink in the lean and creamy white in the fat. Pancetta gives a flatter result, and bacon brings smoke that has no business in this sauce.

Use bronze die spaghetti. The rough, chalky surface left by a bronze extrusion holds sauce in a way a teflon die does not, and it releases more starch into the water. Look for pasta that appears pale and floury rather than yellow and shiny.

Taste the sauce before you reach for salt, then taste it again after the cheese. Guanciale and Pecorino Romano are two of the saltiest ingredients in the Italian pantry and this sauce usually needs none. If the finished pasta is flat, the answer is more black pepper, not more salt.

If you cannot find true peperoncino, use whole dried chillies rather than powder and add them to the hot fat for a few seconds. The heat should sit in the background as warmth, not as a sharp note you can identify.

Common Mistakes

Adding onion or garlic. Neither belongs in the protected recipe. Onion sweetens the sauce and blurs the line between pork fat and tomato, and garlic pushes the plate towards a generic red sauce.

Starting the guanciale in a hot pan or in oil. Hot fat seals the surface of the strips and most of the pork fat never renders, which starves the sauce of the one ingredient that makes it Amatriciana. Start cold, over medium low heat, and give it the full 7 to 9 minutes.

Leaving the guanciale in the tomato. Ten minutes in a simmering sauce turns crisp pork into chewy pork and there is no way back. Take it out after rendering and return most of it in the last thirty seconds.

Draining the pasta in a colander. You lose the starchy surface water that the emulsion depends on, plus a significant amount of heat. Lift the spaghetti across with tongs and always reserve a cup of the cooking water first.

Adding the Pecorino over the flame. Sheep milk cheese seizes above roughly 160°F (70°C) and turns into strings floating in separated fat. Take the pan off the heat, pause fifteen seconds, then add the cheese in two stages while tossing hard.

Using Parmigiano Reggiano instead of Pecorino Romano. Parmigiano is nuttier, sweeter and made from cow milk, and it cannot supply the sharp saline bite that balances the guanciale. If sheep cheese is too strong for you, cut it with a little Parmigiano rather than replacing it.

Wine Pairing

Cesanese del Piglio DOCG: The red of the Lazio hills and the closest thing to a local answer. Its tannin is fine and unaggressive, which matters with a sauce carrying chilli, and it has a dark, faintly peppery berry character that lines up with the cracked black pepper. The acidity resets the palate after the pork fat, and the wine is light enough to be poured through a whole plate of pasta.

Frascati Superiore DOCG: The white drunk with this dish in Roman osterie for a century, and a better match than its reputation suggests. A serious dry Frascati has a firm citrus and white flower profile with a mineral finish from the volcanic soils of the Castelli Romani, and that acidity cuts the rendered guanciale fat more directly than any red. Serve it around 50°F (10°C).

Montepulciano d'Abruzzo DOC: From the region on the other side of the mountains from Amatrice, and a red with the weight the dish needs. Dark plum fruit and soft, rounded tannin with moderate acidity meet the concentrated tomato without the astringency a more structured red brings. Its gentle warmth also takes the edge off the peperoncino, which sharper wines amplify.

Cerasuolo d'Abruzzo DOC: A rosato of real substance made from the same Montepulciano grape, and underrated with tomato and pork. It has the red fruit and light grip of a young red with the acidity and serving temperature of a white, precisely what the emulsified fat calls for. At around 54°F (12°C) it handles the salt of the Pecorino and the chilli without complaint.

Chianti Classico DOCG: The Tuscan option, and the one to pick if the pork is prominent. Sangiovese has high natural acidity and a savoury, sour cherry edge that mirrors the tomato instead of clashing with it, and its grippier tannin has enough fat in the sauce to bind to. Choose a straightforward annata rather than a Gran Selezione.

Storage & Reheating

Dressed Amatriciana does not keep well and is not meant to. Store leftovers refrigerated in an airtight container for up to 2 days, and accept that the pasta will have absorbed sauce and softened overnight. Never freeze the finished dish: the emulsion breaks on thawing and the spaghetti turns to mush.

The tomato and guanciale sauce, made through the simmering stage and cooled quickly, keeps refrigerated in a sealed jar for 4 days and frozen for 2 months. Freeze it without the crisp guanciale and without cheese, both added fresh at the finish, and thaw it overnight in the refrigerator.

To reheat dressed pasta without overcooking it, put it into a wide pan over medium heat with 2 to 3 tablespoons of water, cover, and let the steam work for about 2 minutes, tossing once. Never use a microwave, and never put it back into boiling water. Add a little grated Pecorino off the heat to bring the sauce back together.
