Sugo all'amatriciana (Italian pronunciation: [amatriˈtʃaːna]) or alla matriciana (in Romanesco dialect) is a traditional Italian pasta sauce based on guanciale (cured pork cheek), pecorino cheese, and tomato. Originating from the town of Amatrice (in the mountainous Province of Rieti of Lazio region), the Amatriciana is one of the most well-known pasta sauces in Roman and Italian cuisine. The sauce has been declared as Lazio's Prodotto agroalimentare tradizionale.
Amatriciana originates from a recipe named gricia. Grici were what the Romans called the sellers of bread and comestibles.  They were so called in that a number of them emigrated from the Swiss canton of Grisons.  According to another hypothesis, the name originates from the hamlet of Grisciano, in the comune of Accumoli, near Amatrice. The sauce was (and still is) prepared with guanciale (cured pork cheek) and grated pecorino. According to the matching hypothesis, ingredients reflect local products available either to a simple grocery store or to commonfolk who practised herding in the mountainous area. At some point, a little olive oil was added to the recipe too. It should be noticed that in the 1960s also the Amatriciana sauce was still prepared in this way in Amatrice. 
The invention of the first tomato sauces (and the terminus post quem for the introduction of tomato in the gricia, creating the Amatriciana) dates back to the late 18th century. The first written record of pasta with tomato sauce can be found in the 1790 cookbook L'Apicio Moderno by Roman chef Francesco Leonardi.
The Amatriciana recipe became increasingly famous in Rome over the 19th and early 20th centuries due to the pluricentennial connection between Rome and Amatrice. The recipe was extremely well received and rapidly went on to be considered a "classic" of the Roman Cuisine, even though it originated elsewhere. The name of the dish in the Romanesco dialect eventually became matriciana due to the apheresis typical of this dialect.
While tomato-less gricia is still prepared in central Italy, it is the tomato-enriched amatriciana that is more well known throughout Italy and exported everywhere. While in Amatrice the dish is prepared with spaghetti, the use of bucatini has become extremely common in Rome, and is now prevalent. Other types of dry pasta (particularly rigatoni) are also used, whereas fresh pasta is generally avoided.
The recipe is known in several variants depending among other things on local availability of certain ingredients. While everybody seems to agree about the use of guanciale and tomato, onion is not favored in Amatrice, but is shown in the classical handbooks of Roman cuisine. For frying, olive oil is most commonly used, but strutto (canned pork lard) is used as well.
The addition of garlic sauted in olive oil before adding the guanciale is also accepted, and for cheese either pecorino romano or Amatrice's pecorino (from the Monti Sibillini or Monti della Laga areas) can be used. The addition of black pepper or chili pepper is common.
