Uncooked San Marzano-style tomato sauce

Base ingredients

crushed or hand-passed tomatoes, salt, sometimes fresh basil

Application and bake suitability

Applied thinly (roughly 60-90g per 30cm pizza) since it cooks entirely during the short, hot bake

Relies on very high, short bakes (Neapolitan-style) to cook through without becoming watery on the crust

Preparation and storage

Hand-crushed or passed through a food mill rather than blended — blending whips in air and produces a foamy texture the traditional method avoids. Salted only just before use.

Best made close to use: once salted it releases liquid over time, so it's typically prepared within a few hours of baking rather than stored for days.

Common problems

• Tastes raw or acidic if used on a long, cooler bake that never fully cooks it
• Can make the base soggy if over-applied

Substitutions

• crushed-tomato-sauce (chunkier, more rustic texture, same uncooked bake-through method)
• smooth-tomato-sauce (smoother texture, but it's cooked first, changing the flavour profile)

Pairs well with

Styles using this sauce

• Neapolitan pizzaDefiningWell established

  Cooks entirely during the short, very hot bake, staying bright and fresh rather than reduced.

• Pizza MargheritaDefiningWell established

  Finishes cooking on the pizza itself during the short bake, providing the bright, uncooked tomato layer that gives Margherita its name alongside mozzarella and basil.

• Pizza MarinaraDefiningWell established

  The sole flavour base of the style given its total absence of cheese, so its brightness and seasoning carry the whole pizza rather than sharing the stage with a melted layer.

• Pizza canottoTraditionalGenerally accepted

  Applied sparingly, in keeping with canotto's traditionally light topping load, so it doesn't compete with the exaggerated, bread-like rim for attention.

• MontanaraTraditionalGenerally accepted

  Applied after the initial fry, on the same short finishing bake as a conventional Margherita, so it stays bright rather than reducing further.

Naples' Verace Pizza Napoletana standard specifies raw, hand-crushed tomato applied uncooked and cooked entirely by the pizza's own short, very hot bake.

History and cultural context

The Sarno valley south-east of Naples, where the San Marzano dell'Agro Sarnese-Nocerino cultivar has DOP protection. The Neapolitan convention of dressing pizza with crushed raw tomato rather than a cooked sauce is tied to having a tomato good enough not to need cooking.

Traditional regions: Campania, Agro Sarnese-Nocerino, Naples

'San Marzano' appears on far more tins than the protected DOP acreage could supply. Only DOP-marked tins with a consortium number are the protected product; the rest are the cultivar grown elsewhere, or another plum tomato entirely.

The uncooked-crushed-tomato method spread internationally with the Neapolitan revival from the 2000s and is now standard in artisan pizzerias worldwide.

Italian-American pizzerias, unable to source Italian tomatoes reliably, developed cooked, seasoned, often sweetened sauces instead — which is why American pizza sauce and Neapolitan pizza dressing are genuinely different preparations rather than the same thing made differently.

Whether a non-DOP San Marzano-type tomato is an acceptable substitute is argued sharply; the AVPN standard permits several specified tomato types, not San Marzano alone.
