San Marzano Tomatoes
The gold standard of Italian canned tomatoes, San Marzano is a specific variety of plum tomato grown in the rich volcanic soil of the Sarno River valley near Naples, Italy. Prized for their exceptional sweetness, low acidity, and easy-to-peel flesh, they are the tomato of choice for authentic Neapolitan pizza and marinara sauce.
True San Marzano tomatoes (Pomodoro S. Marzano dell'Agro Sarnese-Nocerino) carry a DOP (Denominazione di Origine Protetta) designation — a European protected status ensuring authenticity. They must be grown in a specific area near Naples, in the volcanic soil of Mount Vesuvius, harvested by hand, and processed in a specific way.
Many canned tomatoes labeled "San Marzano style" or simply "San Marzano" in the US are not DOP-certified. Look for the DOP seal on the can for the real thing.
Flavor: Distinctly sweet with remarkably low acidity — a balanced, complex tomato flavor that needs little added sugar or long cooking to be delicious.
Texture: Meaty with dense flesh, few seeds, and an easy-to-remove skin. The flesh is firmer and less watery than standard plum tomatoes.
Pizza Sauce
The Neapolitan pizza standard — crush by hand with salt, olive oil, and basil only
Marinara
Simple 20-minute sauce where the tomato quality shines without masking
Braising
Use as a base for braised meats — the low acid won't fight the protein
Pasta al Pomodoro
Simple pasta with tomato sauce — quality ingredients are everything
Most widely available in canned form. When buying:
- • Look for the DOP seal for authentic Italian-grown San Marzanos
- • Whole peeled canned tomatoes are most versatile — crush by hand as needed
- • Ingredients should be: tomatoes, tomato juice/purée, salt, basil leaf — nothing else
- • Fresh San Marzanos are occasionally available at specialty markets in late summer
