Canned San Marzano Tomatoes
Sweet and mildly tangy with a smooth, less acidic finish than typical canned tomatoes.
Lens analyzedSan Marzano tomatoes are a plum tomato variety canned whole in their own juice, known for a sweeter, less acidic flavor and fewer seeds than standard canned tomatoes. Their thinner flesh breaks down smoothly into sauce with less cooking time. They're a common base for simple tomato sauces where the tomato flavor needs to stand on its own.
Where it comes from
San Marzano tomatoes are grown in the volcanic soil near Mount Vesuvius in Italy's Campania region, where the variety earned a protected designation of origin for authentic bottles. The name is now also used more loosely on some cans grown outside that region, so the label alone doesn't guarantee the true variety.
Buying it
Look for cans that specify D.O.P. certification if you want tomatoes actually grown in the protected Italian region, since the San Marzano name isn't always regulated on every label. Check that the can isn't dented, rusted, or bulging.
Storing it
Store unopened cans in the pantry, where they keep for about a year; refrigerate any leftover tomatoes in a sealed container once opened and use them within a few days.
Keeps about 1 year in the pantry.
