Pasta alla Gricia: the Roman Guanciale Pasta, Done Right

What is pasta alla gricia?

Pasta alla gricia is a Roman pasta dressed with rendered guanciale (cured pork jowl), finely grated Pecorino Romano and black pepper. The unlisted fifth ingredient is the pasta’s own starchy cooking water. There is no egg, no tomato, no butter, no cream and, in today’s Roman version, no onion or garlic. The sauce is an emulsion: rendered jowl fat broken into tiny droplets in starchy water, held there by starch and by the proteins in the cheese. Done right it is glossy and clings to every tube; done wrong it is a slick of grease with clumps of cheese in it.

Gricia is pronounced GREE-cha. Romans also call it amatriciana bianca, white amatriciana, and it has a blunter nickname, cacio e unto, ‘cheese and grease’, which the Roman chef Arcangelo Dandini uses (caciu e untu in the Amatrice dialect). It is usually made with rigatoni or mezze maniche in Rome today, and spaghetti or bucatini work too.

It sits in the middle of Rome’s four famous pastas. Our cacio e pepe page draws the family tree: start with cacio e pepe (pasta, Pecorino, pepper, water). Add guanciale and you have gricia. Add tomato to gricia and you have amatriciana; add egg and you have carbonara. As on our carbonara page, read that as a cook’s map rather than a pedigree: carbonara is the youngest of the four (first recorded in 1939, first printed as a recipe in 1952) and borrowed its pantry from the others, and the order in which the other three were invented is a good argument, not a documented fact (more below).

The dish looks like three ingredients and a shrug, which is why so many versions fail. Joël Robuchon’s line, quoted by Serious Eats in its own gricia recipe, fits: ‘The simpler the food, the harder it is to prepare well.’

Gricia vs carbonara, amatriciana and cacio e pepe

The real difference between the four is what holds the sauce together, and so what can go wrong.

Carbonara adds egg. Yolk is an emulsifier and a thickener, so it gives the sauce a safety net and a new risk: the egg sets and scrambles if the pan is too hot. Gricia has no egg, so the only things holding its fat in water are pasta starch and cheese protein, and the risk is cheese clumping, not scrambling. Alessandro Roscioli of Rome’s Roscioli, recalling how his restaurant’s first gricias failed, points out that in carbonara you can loosen the pecorino and egg cream with guanciale fat, while ‘nella Gricia non puoi’: in gricia, you can’t (as reported by Passione Pasta). If your carbonara keeps splitting, practice on gricia: it teaches the fat-and-starch glaze the egg sits on. Our spaghetti carbonara and carbonara sauce pages take it from there.

Amatriciana adds tomato (and, in Amatrice, a little chili). Tomato brings water, body and acid, which makes its sauce far more forgiving. It is also the only one of the four with a legal definition: ‘Amatriciana Tradizionale’ has been an EU Traditional Speciality Guaranteed since 2020 (Regulation (EU) 2020/395). Gricia has no legal specification at all, which is one reason its recipes vary so much.

Cacio e pepe drops the pork. It is a cheese-in-water sauce with no added fat, so it needs far more cheese (our cacio e pepe uses 7 oz (200 g) for 14 oz (400 g) of pasta) and is the most fragile of the four. Gricia is the reverse: a fat-in-water emulsion in which the rendered jowl fat is the main event and the Pecorino is a binder and a seasoning, so this recipe uses 2 1/2 oz (70 g) of cheese in the sauce for the same amount of pasta. Same cheese, same pepper, same pasta water, different architecture.

The name: Rome’s grocers, a mountain hamlet, or neither

Most pages repeat two stories about the word gricia and pick one. Here is what the documents actually show.

The word is older than the dish, and it was an insult. The Roman dialect poet Giuseppe Gioachino Belli used ‘griscio’ in his sonnets in the 1830s. In ‘Er galantomo’ (1 October 1831) his note glosses it as the name given to the orzaroli, Rome’s grocers who sold bread, flour, pasta, oil and other staples. In ‘Er carnovale der trentatre’ (10 February 1833) he hurls it at Pope Gregory XVI: ‘Ah ggriscio, rafacàno, pataccone!’ And in an 1835 note Belli says who these people were: ‘Nome appellativo degli indigeni del Lago di Como’, a name for natives of Lake Como who came to Rome to scrape a living in small trades and save up to buy land back home. So Belli himself puts them at Lake Como, not in the Swiss Grisons that most recipe pages name.

Theory one, then, is that pasta alla gricia means pasta ‘the way the grici make it’. The Treccani dictionary takes this line and hedges on where the grici came from: the Swiss Grisons, the Valtellina (which the Grisons ruled from 1512 to 1797) or perhaps Friuli. The word is solidly documented; the link between the grocers and this particular pasta is not. No document ties the recipe to them.

Theory two is Grisciano, a hamlet of Accumoli on the Via Salaria near Amatrice, which holds its own Sagra della Gricia festival. This one is in print by 1960: a review of Alberto Consiglio’s 1959 book La storia dei maccheroni in the Trieste paper Il Piccolo (19 July 1960) mentions ‘vermicelli alla gricia’ and glosses ‘«gricia» da Griciano, un paesino prossimo ad Amatrice’, gricia from Griciano, a village near Amatrice. Consiglio’s ‘vermicelli alla gricia’ is the earliest ‘alla gricia’ in print we could find, and the village gloss may be his or the reviewer’s. Buccini, in a 2006 paper for the Oxford Symposium on Food and Cookery, argued that ‘alla grisciana’ was reshaped into ‘gricia’ to fit occupational dish names such as carbonara and carrettiera.

Neither side can win on spelling. Belli writes ‘griscio’ with the same -sc- as Grisciano, so the Grisciano camp’s spelling argument proves nothing. Belli also uses ‘griscio’ in another sonnet to mean grey, a dialect form of grigio, which is one more reason to be careful with neat derivations (that last point is our inference). The honest verdict: both theories are plausible, the grocers’ word is older, the village link is, as far as we found, the older of the two in print for the dish, and nothing yet settles it.

Is gricia really the ancestor of amatriciana?

‘Gricia is the oldest Roman pasta, and amatriciana is just gricia plus tomato’ is the most repeated claim about this dish. It is plausible as logic and not documented as history.

The logic is sound. Tomato is a New World plant, and in Italian cookbooks it met pasta only around 1800. Antonio Latini printed a ‘Spanish-style’ tomato sauce in Naples in 1692, but not for pasta; the Roman cook Francesco Leonardi’s L’Apicio moderno pairs tomato with pasta around 1800 (sources disagree on whether the 1790 first edition or the 1807 edition has it); and Ippolito Cavalcanti’s Neapolitan vermicelli with tomato, from the late 1830s, is the canonical early recipe. A mountain dish of cured jowl, sheep’s cheese and pasta needs no tomato, so a tomato-less version could easily be older. The shepherd version of that story, told most often, has shepherds on the transhumance routes around Amatrice carrying what kept: guanciale, pecorino and flour. Treat it as our cacio e pepe page treats its own shepherd story, as the usual telling, not documented history. Even the 2017 Italian application for the amatriciana designation, which tells it, lists flour rather than dried pasta and no pepper, and pepper was a bought trade good, not something a flock provides.

The printed record runs the other way round. Ada Boni’s La cucina romana (undated, usually given as 1929), the classic early collection of Roman home cooking, gives spaghetti ‘alla matriciana’ and, according to two independent accounts of the book, a variant ‘alla marchiciana’, without tomato and with sliced guanciale: the dish, under another name. The Touring Club Italiano’s 1931 gastronomic guide lists Rome’s spaghetti as matriciana (with tomato, and with onion and lard), cacio e pepe, anchovy, tuna and aglio e olio, and no gricia at all. The name ‘alla gricia’ is in print by 1959. The first printed claim that gricia is the ‘capostipite’, the founding ancestor, that we found is Secondino Freda’s, in the Strenna dei Romanisti of 21 April 1983: gricia, he wrote, can claim the title ‘sia per l’anzianità che per la prevalenza del condimento a base di maiale’, by age and by its pork-based dressing. His own recipe started with olive oil or lard, and guanciale or pork belly.

So: gricia is very probably the older idea and amatriciana the tomato version of it, but the claim is a Roman tradition and a sensible inference, not a fact with a date. And the pages that say gricia was ‘invented around 400 AD in the taverns of ancient Rome’ are wrong on every count: there is no evidence of boiled dried pasta in ancient Rome, dried pasta is first documented as an industry in Sicily in 1154, and Rome’s pasta makers only formed their guild in 1642.

The emulsion, with numbers

No ranking recipe gives you a temperature for the cheese. Here is where ours comes from. Pecorino Romano’s proteins aggregate when heated in water, and they do it more, not less, as the water gets hotter. The Pecorino Romano consortium’s own gricia recipe says the cheese’s casein ‘coagula a 55 °C’ (131°F) and rests the pasta off the heat for a minute before adding it. A 2025 study in Physics of Fluids by Bartolucci and colleagues, the cacio e pepe paper, found cheese in plain hot water forming large clumps at about 65°C (149°F). That puts 140°F (60°C) inside the trouble zone, not below it: it works because of the starch (next paragraph), which keeps the cheese smooth well above 131°F (55°C). So aim for about 140°F (60°C) or a little below, clear of the big-clump zone. That takes longer than the consortium’s one-minute rest suggests. By our estimate a full pan of pasta just off the boil is still around 165 to 185°F (75 to 85°C) after a minute off the heat, so toss for 1 to 2 minutes and check with an instant-read thermometer, or do as Dandini does and move the pasta to a room-temperature bowl, which pulls the heat out much faster.

Starch is the other lever. The same study found that when starch fell below about 1% of the cheese’s weight the whole sauce clumped, and that 2 to 3% kept it smooth. Ordinary pasta water carries only a little; water that has been reduced carries much more. That is the scientific case for the Roman method in this recipe: cook the pasta in less water than usual, then finish it in the pan so it keeps shedding starch into a sauce that is reducing around it.

America’s Test Kitchen tried the Roman method and called it more art than science, because the amount of water you need depends on how much the pasta drinks. Its fix: cook the pasta fully in half the usual water, then boil 2 cups (480 ml) of pasta water with about 1/3 cup (75 ml) of fat down to exactly 1 1/2 cups (360 ml) before the pasta and cheese go in. It is a good method and a useful check. If you are nervous, use their target: the milky fat-and-water mixture should measure about 1 1/2 cups (360 ml) before the pasta goes in.

There is a third Roman way, the crema. Dandini works grated Pecorino with the rendered fat and a ladle of pasta water into a cream in a big bowl, then tosses the barely cooked pasta in the bowl, never on the flame. The consortium’s chef whisks cheese with an equal weight of lukewarm water into a thick cream and spoons it over the plated pasta. All three routes obey the same rule: the cheese never meets boiling liquid.

Why no butter or cream? The rendered fat is already the fat in the emulsion, and dairy would dilute the jowl’s flavor. The pork fat and the starch do the job cream does in the shortcut versions.

The schools: crisp or soft, onion or not, pepper or not

Romans argue about gricia. This recipe picks a path, and here are the others, because they are not wrong, just different.

Crisp or soft guanciale. Serious Eats, Dandini and the consortium cook it crisp; America’s Test Kitchen stops at ‘deep golden brown but still has slight pinkish hue’. Rachel Roddy, the Rome-based food writer, wants it soft and never ‘brown and crisp, which would negate the pleasure of biting into soft, fatty, sweetly flavored curls’ (as quoted by Food52). Our batons sit in between: crisp edges, yielding centers, fat translucent rather than grey. Roscioli goes the other way on heat, putting the guanciale into a very hot pan and then lowering the flame so it sweats.

Onion. Today’s orthodoxy says never, but onion used to be normal. The New York Times printed chef Sandro Fioriti’s gricia with ‘1 small onion, sliced thin’ in January 2008, and English-language guides from 1997 to Lonely Planet’s 2017 Rome described gricia as pasta with pig’s cheek and onions. The strict no-onion, no-oil rule is younger than it looks. We leave onion out because it makes the sauce sweeter and wetter; if you like it, soften it slowly in the fat after the guanciale comes out.

Pepper. Pepper is in almost every modern recipe, including ours, but Dandini says flatly that historically it isn’t part of gricia: ‘niente pepe’. White wine is another split: some Roman cooks deglaze with a splash once the guanciale is crisp, while Serious Eats, America’s Test Kitchen, Dandini, Roscioli and the consortium skip it and let the pasta water lift the browned bits. If you use it, 1/4 cup (60 ml) of dry white, boiled off completely before the water goes in.

Shape. Serious Eats and America’s Test Kitchen use rigatoni, Roscioli uses mezzi rigatoni, the consortium uses mezze maniche and Dandini uses fettuccelle. Short ridged tubes suit a sauce that is mostly fat and only lightly cheesed, and they trap the batons. Long shapes need more sauce to coat them.

Substitutes, with the arithmetic

Guanciale, when you can get it. It is jowl, not belly, and much fattier: a typical Italian guanciale label gives about 68 g of fat per 100 g, against 37 g for raw US bacon in the USDA database. It renders into a clear, fragrant fat, and its cure is salt and pepper, with no smoke. A well-stocked Italian deli will cut it to order. Ignore ‘Guanciale Amatriciano IGP’ on shop pages: as of September 2026 the EU’s eAmbrosia register lists no protected designation for guanciale at all. The only protected Amatrice pork product is Prosciutto Amatriciano PGI, and ‘guanciale del tipo Amatriciano’ exists only as an ingredient definition inside the amatriciana TSG.

Pancetta is the honest substitute. America’s Test Kitchen builds its whole gricia on it (and titles the recipe ‘rigatoni with pancetta and Pecorino Romano’). Buy unsmoked flat pancetta in a piece, cut the same batons, expect it to render faster (ATK says 8 to 10 minutes) and to give less fat, and top up with olive oil to reach the 1/4 cup (60 ml).

Bacon works in a pinch but changes the dish. US bacon is smoked and Italian pancetta and guanciale are not, and smoke fights sheep’s-milk cheese. It also has about half the fat per gram of guanciale, so you will need oil to make up the fat. Some cooks simmer bacon for a minute or two and dry it before rendering; that mutes the smoke and some of the salt, but does not remove them. Call the result ‘gricia-style’, as the more honest recipe writers do.

Pecorino Romano, not ‘Romano’. Under US rules (21 CFR 133.183) a cheese labeled simply ‘Romano’ may be made from cow’s, sheep’s or goat’s milk. Look for Pecorino Romano DOP, which must be made from whole sheep’s milk; most of it comes from Sardinia rather than Lazio. A newer grade, Pecorino Romano DOP Riserva (added in 2026), is aged at least 18 months and capped at 4% salt as sold. Parmigiano-Reggiano can stand in, as many cooks do; it is milder and less salty, so taste for salt at the end. Grate it yourself: pre-grated cheese is coated in cellulose to stop it caking, and the coating that keeps it loose in the tub keeps it from melting smoothly into a sauce.
