Disclosure: We are participating in an educational campaign for San Marzano DOP tomatoes. We were supplied with authentic San Marzano tomatoes by the consortium for Pomodoro San Marzano dell’Agro Sarnese-Nocerino DOP.

This sauce is perfect for making traditional Italian dishes like spaghetti and meatballs, lasagna, and pizza. San Marzano tomato sauce is also great for dipping breadsticks or adding to chicken or fish, like our halibut Provencal.

This quick and easy sauce features the unique flavor of San Marzano DOP tomatoes. We didn’t add an excess of ingredients because we wanted the flavor of the tomatoes to shine in this authentic Italian tomato sauce. 

Here is Why This Recipe Works:

  • Starting with real San Marzano DOP tomatoes offers exceptional flavor and texture.
  • Only a few ingredients are needed to complement the flavor and keep the tomatoes the star of the show
  • Since oregano is fat-soluble, we saute it in olive oil to release its flavors before adding the tomatoes.
  • This recipe doesn’t call for sugar or carrots because San Marzano DOP tomatoes are sweet and low in acid. They don’t need the additional ingredients.
  • A short simmer brings out richness and depth of flavor and allows the herbs time to infuse into the sauce.
  • Spread it on a quick pizza dough,  add your favorite toppings, and bake for a delicious pizza night at home.

What’s So Special About San Marzano DOP Tomatoes?

Many cans of San Marzano tomatoes do not have the DOP emblem on them, which means they do not meet the quality standards of the Italian government. You might even be purchasing tomatoes grown in the U.S.

San Marzano DOP tomatoes are a variety highly prized for their flavor, color, and texture. They are grown in the rich volcanic soils in the Agro Sarnese – Nocerino area, just south of Naples, Italy. 

Even though San Marzano tomatoes can be grown anywhere globally, there is something special about the tomatoes grown in this small volcanic region of Southern Italy.

The volcanic soil, the climate, and the processing method all contribute to these tomatoes’ unique, sweet flavor, aroma, and low acidity. Only tomatoes that meet specific quality standards can be labeled as San Marzano DOP tomatoes.

Not all cans of San Marzano tomatoes come from the volcanic soils of Southern Italy in the Agro Sarnese – Nocerino area.

When looking for San Marzano tomatoes, you may see cans that say “Product of Italy” or “Imported from Italy” or even “certified.” These are not the same as DOP tomatoes, but they are often priced the same.

If you want to make sure you have the real deal, look for the DOP certification seal on the can.
