San Marzano Tomatoes for Pizza

Few ingredients are as closely associated with Neapolitan pizza as San Marzano tomatoes.

They are valued for rich tomato flavour, natural sweetness, balanced acidity and fleshy texture.

Naples classes teach the tomato technique alongside the dough, and the popular ones fill several days ahead — check live dates before you plan around one.

What Are San Marzano Tomatoes?

San Marzano tomatoes are a type of plum tomato traditionally associated with the Campania region of southern Italy.

They are usually elongated and particularly suited to sauces.

Why Are They Used on Neapolitan Pizza?

Neapolitan pizza uses relatively few ingredients.

San Marzano tomatoes can create a rich, fresh sauce without requiring long cooking, sugar or heavy seasoning. That restraint is the whole point of the style — see our guide to what Neapolitan pizza is for how the toppings sit alongside the dough and the oven.

What Do They Taste Like?

Good examples are often:

• slightly sweet
• rich
• fruity
• balanced in acidity
• fleshy rather than watery

Quality still varies by producer and harvest.

San Marzano vs Plum Tomatoes

San Marzano is one type of plum tomato.

Not every plum tomato is San Marzano, and not every product carrying the name is automatically superior.

Quality matters more than prestige.

What Does DOP Mean?

Some Italian San Marzano tomatoes carry the protected designation:

Pomodoro San Marzano dell’Agro Sarnese-Nocerino DOP

DOP indicates defined geographical origin and production standards.

You do not need DOP tomatoes to make excellent pizza at home.

Other Naples Food Experiences You Might Enjoy

Tinned tomatoes travel; the technique does not. In Naples’ Centro Storico — the streets around Spaccanapoli and Naples Cathedral, a short walk from the Campania countryside where these tomatoes are grown — you can book hands-on Neapolitan pizza classes, pizza and tiramisu workshops, pizza and gelato making classes, wood-fire oven sessions with a working pizzaiolo, and full Neapolitan cooking classes covering pasta and antipasti. Most run 2–3 hours and end with you eating what you made.

Should Pizza Sauce Be Cooked?

For traditional Neapolitan-style pizza, usually not.

The tomatoes can simply be crushed, lightly salted and spread directly onto the dough.

Simple San Marzano Pizza Sauce

Ingredients

• 400 g whole peeled San Marzano tomatoes
• 4–5 g fine sea salt
• optional fresh basil

Method

1. Place tomatoes in a bowl.
2. Remove some packing liquid if excessively watery.
3. Crush gently by hand.
4. Add salt.
5. Taste.
6. Refrigerate until needed.

Should You Blend the Tomatoes?

You can, but hand-crushing gives more control and avoids an overly thin or foamy sauce.

How Much Sauce Per Pizza?

Around 60–80 g for a 28–30 cm pizza is a useful starting point.

That pairs with a dough ball of roughly 245–250 g — the weights are set out in full in our Neapolitan pizza dough recipe.

Should You Add Sugar?

Usually not.

Good tomatoes should contain enough natural sweetness.

Should You Add Garlic or Oregano?

It depends on the pizza.

For Margherita, keep the tomato simple — the flavour comes from the interplay of tomato and mozzarella, not from seasoning.

For Marinara, garlic and oregano are defining flavours.

Fresh vs Canned Tomatoes

Excellent fresh tomatoes can work, but high-quality canned whole tomatoes are often more reliable year-round.

Whole Tomatoes vs Ready-Made Sauce

Whole peeled tomatoes let you control salt, texture, thickness and seasoning.

Passata vs Whole Tomatoes

Passata can work, but it produces a smoother texture.

Common Mistakes

• using too much sauce
• cooking the sauce for hours
• over-seasoning
• using all the tin liquid automatically
• over-blending
