Ingredients

Ingredients for san marzano tomato sauce.

  • Garlic: Fresh garlic brings the dish to life, adding aromatic and savory notes. Use fresh garlic whenever possible for a stronger, more flavorful sauce.
  • San Marzano Tomatoes: Known for their sweet flavor and fewer seeds, San Marzano tomatoes are the secret to a perfectly smooth and rich sauce. Look for DOP-certified San Marzano tomatoes for the most authentic taste.
  • Dried Oregano: A staple herb in Italian cooking, it complements the tomatoes and gives the sauce a traditional flavor.
  • Parmesan Rind: When simmered, the parmigiano reggiano rind infuses the sauce with a savory, umami-rich flavor that can’t be beat.
  • Unsalted Butter: Adds a velvety texture and richness that balances out the acidity of the tomatoes.
  • Fresh Basil Leaves: Fresh basil is essential for finishing the sauce, adding a burst of fresh, herbaceous flavor right at the end.

Roma Tomato vs San Marzano

When it comes to making the perfect tomato sauce, the choice between Roma tomatoes and San Marzano tomatoes can make a big difference in flavor and texture. Roma tomatoes, often referred to as plum tomatoes, are known for their meaty flesh and fewer seeds, making them a great option for sauces that need a bit of a thicker consistency.

They have a slightly tangy flavor and are widely available at most grocery stores. On the other hand, San Marzano tomatoes are prized for their sweet flavor, low acidity, and fewer seeds, offering a smoother, richer taste that many consider the gold standard for Italian sauces.

Grown in the volcanic soil of the San Marzano region in Italy, these tomatoes have a protected designation of origin (DOP), meaning they’re cultivated under strict conditions for superior flavor. While both types make delicious sauces, San Marzano tomatoes are often the go-to for those seeking a more authentic and flavorful Italian tomato sauce.

Notes

Use a non-reactive pot: Always cook tomato sauce in a stainless steel or enameled cast iron pot to preserve the flavor and avoid any metallic taste.
Simmer on medium-low heat: Keep the heat low to let the flavors meld together slowly without burning or overcooking the garlic and tomatoes.
Remove the Parmesan rind before serving: It’s easy to forget, but be sure to remove the Parmesan rind after simmering—it’s just for flavor, and not meant to be eaten.

  1. I use San Marzano tomatoes all the time, and it really is important to purchase those with DOP.

    Any canned tomatoes using the San Marzano name without this stamp ARE NOT San Marzano. Italy has had an issue with fake product hence this stamp!!!
