Authentic San Marzano Tomato Sauce – A Classic Italian Staple
When it comes to Italian cuisine, nothing beats a rich, velvety tomato sauce made from San Marzano tomatoes. Whether you’re preparing a Sunday dinner, holiday meal, or quick weeknight pasta, this sauce brings authentic flavor and comfort to any table.
What makes this recipe truly exceptional is its simplicity. With just a handful of ingredients and minimal preparation, the natural sweetness and low acidity of San Marzano tomatoes shine through, creating a sauce that’s both timeless and deeply satisfying.
🍅 Why San Marzano Tomatoes Are the Gold Standard
Grown in the sun-drenched volcanic soil near Mount Vesuvius in Italy’s Campania region, San Marzano tomatoes are known for:
- Naturally sweet flavor
- Low acidity – gentle on the stomach
- Dense, meaty texture with fewer seeds
- Thin skin for easy cooking
Unlike typical plum tomatoes, San Marzanos require little to no sugar to balance their flavor, making them perfect for homemade sauces where quality and taste truly matter.

👩🍳 Step-by-Step Instructions
Step 1: Sauté Aromatics
- In a large saucepan or Dutch oven, heat 3 tablespoons of olive oil over medium heat.
- Add the finely chopped onion and cook for 3–4 minutes, until softened and translucent.
- Stir in the minced garlic and sauté for another 1–2 minutes, until fragrant.
🔥 Be careful not to brown the garlic — it should stay golden for the best flavor.
Step 2: Add Tomatoes
- Open your cans of San Marzano tomatoes. If using whole tomatoes, crush them by hand or pulse briefly in a blender for a slightly chunky texture.
- Add the tomatoes (and their juices) to the pot.
- Stir in dried oregano and dried basil.
- If desired, add ½ teaspoon of sugar to enhance the sweetness (usually not needed with San Marzanos).
Step 3: Simmer Slowly
- Bring the sauce to a gentle simmer.
- Reduce heat to low and let it simmer uncovered for 30–45 minutes, stirring occasionally.
- Season with salt and pepper to taste.
⏱️ The longer it simmers, the deeper the flavor. For best results, simmer up to an hour.
Step 4: Blend (Optional)
If you prefer a smoother texture:
- Use an immersion blender directly in the pot, or
- Transfer the sauce to a blender, blend until smooth, and return to the pot.
For a more rustic, chunky sauce, skip this step.
Step 5: Finish and Serve
- Stir in fresh basil right before serving for an aromatic burst.
- Spoon over your favorite pasta, gnocchi, or ravioli.
- Top with freshly grated Parmesan cheese and a drizzle of extra virgin olive oil.
🍝 This sauce also makes a fantastic base for pizza, baked ziti, eggplant parmesan, or lasagna.
