Passata

Also: passata di pomodoro, tomato passata, strained tomatoes, sugo di pomodoro crudo

A smooth, vibrant Italian tomato product made by puréeing and sieving raw or briefly cooked tomatoes, retaining fresh flavour and a loose, pourable consistency distinct from concentrates, crushed tomatoes, or cooked sauce.

/pah-SAH-tah/Italian — from passare (to pass through), referring to the action of pushing raw or briefly blanched tomatoes through a food mill or sieve (passatutto) to produce a smooth, seedless purée.

Definition

Passata di pomodoro is not a finished sauce — it is an intermediate tomato preparation: a strained purée of very ripe tomatoes that has been passed through a food mill or fine sieve (passatutto or mouli légumes) to remove seeds and skins while preserving the bright, raw flavour and vivid colour of fresh fruit. The result is a smooth, deep-red liquid whose consistency is thinner than tomato paste but thicker than tomato juice, typically sitting between 70 and 120 g of solids per litre. Passata can be raw (cruda), in which raw ripe tomatoes are immediately milled — preserving maximum volatiles and a distinctly fresh, almost green note — or lightly cooked (cotta), where tomatoes are briefly blanched or heated to collapse the flesh before milling, producing a slightly sweeter, more stable product. Italian home cooks and producers traditionally make large-batch passata in late summer using San Marzano, Roma, or other plum tomato varieties, bottling it in glass jars to last the year. Distinctions from related products: Crushed tomatoes (pelati schiacciati) retain visible chunks, seedy texture, and greater structural variation. Tomato paste (concentrato di pomodoro) is cooked down to a thick, intense, almost jammy concentrate of 28–30% solids, used in tablespoon quantities as a flavour amplifier. Canned whole peeled tomatoes (pelati) require the cook to break them down manually. Passata occupies the middle ground: pre-broken, seedless, smooth, still relatively raw in flavour — a blank canvas for rapid sauce building. In sauce building, passata is often added after soffritto and aromatics have been built in fat; it reduces in the pan over 15–25 minutes, losing moisture, concentrating flavour, and losing the rawness of fresh tomatoes. This brief cooking distinguishes a sugo from passata used as a base ingredient. Passata's loose texture also makes it useful in pizza sauce (often used completely raw, spread directly on dough before baking), braises, and soups where a concentrated paste would overwhelm other elements.

“She stirred the passata into the soffritto of onion and olive oil, let it simmer hard for twenty minutes until the colour deepened from orange-red to a vivid ruby, then seasoned and called it sauce.”

Notes

Raw vs. briefly cooked

Raw passata (cruda) made from fully ripe summer tomatoes retains a bright, almost grassy top note from volatile compounds (cis-3-hexenal, geranial) that are driven off by heat within the first few minutes of cooking. Lightly cooked passata develops a rounder, sweeter note as sugars concentrate and the Maillard reaction begins to occur on the solids coating the pan walls. Neither is superior; they serve different flavour goals.

Passata vs. crushed tomatoes

The key practical difference is texture and flavour uniformity. Crushed tomatoes contain visible chunks of varying ripeness and fibrous skin remnants, giving rustic, varied texture well suited to long braises. Passata is homogeneous and seedless — it integrates smoothly into sauces and produces a restaurant-clean result with shorter cooking times. Many Italian-American recipes that call for crushed tomatoes would be improved by passata when a smoother sauce is the goal.

Bottling passata at home

Traditional Italian preservation (conserva) involves filling glass bottles with raw passata, adding a basil leaf, capping, and hot-water bathing at 100 °C for 40 minutes to achieve commercial sterility. The acidity of ripe tomatoes (pH typically 4.0–4.4) is sufficient to prevent Clostridium botulinum growth in most cases, but the USDA recommends adding citric acid or lemon juice to ensure safety regardless of tomato variety.
