Equipment You’ll Need

• Medium saucepan or Dutch oven (3-4 quarts)
• Can opener
• Wooden spoon

Ingredients

• 1 (28-ounce) can whole peeled tomatoes, preferably San Marzano
• 5 tablespoons unsalted butter
• 1 medium yellow onion, peeled and cut in half
• Salt to taste

Instructions

1. Combine all ingredients in the saucepan. Place the canned tomatoes (and their juices), the unsalted butter, and the two halves of the onion into a medium saucepan over medium heat.
2. Bring to a simmer. Stir to combine and allow the butter to melt. Once the mixture begins to bubble, reduce the heat to low to maintain a very gentle, lazy simmer. The sauce should have small bubbles breaking the surface, but it should not be boiling vigorously.
3. Simmer for 45 minutes. Let the sauce cook, uncovered, for 45 minutes. Stir it occasionally, using your wooden spoon to break up the whole tomatoes against the side of the pot as they soften. The sauce will thicken and the color will deepen.
4. Discard the onion. After 45 minutes, the sauce will be fragrant and slightly thickened. Remove and discard the onion halves. They have imparted their flavor and are no longer needed.
5. Season and serve. Stir the sauce well and taste it. Add salt as needed until the flavors are bright and balanced. Your sauce is now ready to be tossed with hot, cooked pasta.

Expert Cooking Tips

• Use the Best Tomatoes: The quality of your tomatoes is paramount as they are the star of the show. San Marzano D.O.P. tomatoes are highly recommended for their natural sweetness and low acidity, which creates a more balanced sauce.
• Don’t Cut the Onion: The onion is meant to infuse the sauce with a subtle sweetness, not to be eaten. Keeping it in large halves allows it to release its flavor gently without breaking down and makes it easy to remove.
• Maintain a Gentle Simmer: Do not boil the sauce. A low, slow simmer is crucial. This allows the flavors to meld together beautifully and prevents the tomatoes from developing a bitter or scorched taste.
• Crush as You Go: Gently press the whole tomatoes against the side of the pot with your spoon as they cook. This helps them break down naturally into a rustic, yet smooth consistency without the need for a blender.
• Don’t Skimp on the Butter: The butter is the secret to this sauce’s luxurious, velvety texture. It emulsifies with the tomato juices, taming their acidity and creating a rich mouthfeel that olive oil simply cannot replicate.

Substitutions and Variations

While the beauty of this recipe lies in its specific ingredients, some adjustments can be made. Tomatoes: If you cannot find San Marzano, use the highest quality canned whole peeled tomatoes available. Avoid diced tomatoes, as they often contain calcium chloride, which prevents them from breaking down properly. Butter: For a dairy-free version, you can substitute a high-quality olive oil, but be aware this will fundamentally change the flavor and iconic creamy texture of the sauce. Onion: A sweet or white onion can be used, but a classic yellow onion provides the most balanced, traditional flavor.

Common Mistakes to Avoid

A common mistake is cooking the sauce at too high a temperature. A vigorous boil will cause the sauce to reduce too quickly and can create a harsh, acidic flavor. The key is a gentle, lazy simmer. Another pitfall is not cooking it long enough. The 45-minute simmer is essential for the flavors to fully develop and meld. Rushing the process will result in a less flavorful, less cohesive sauce. Finally, don’t be tempted to add garlic or herbs on your first try. The genius of this recipe is its purity; experience it as Marcella intended before you consider any variations.

Serving Suggestions

This sauce is classically served tossed with a pound of cooked pasta, such as spaghetti, rigatoni, or penne. Finish with a generous amount of freshly grated Parmigiano-Reggiano cheese. Beyond pasta, it’s a phenomenal sauce for homemade pizza, a base for chicken or eggplant parmesan, a dipping sauce for breadsticks or arancini, or a simple, elegant topping for polenta.

Storage and Reheating Tips

Allow the sauce to cool completely before storing. It can be kept in an airtight container in the refrigerator for up to 5 days. This sauce also freezes exceptionally well. Pour the cooled sauce into freezer-safe bags or containers, leaving a little room for expansion. It can be frozen for up to 3 months. To reheat, thaw overnight in the refrigerator and then gently warm in a saucepan over low heat.

Frequently Asked Questions

Is it necessary to use San Marzano tomatoes?

While not strictly necessary, using authentic D.O.P. San Marzano tomatoes is highly recommended. They have a superior sweetness, lower acidity, and fewer seeds, which contributes significantly to the final quality and flavor of this simple sauce.

Can I add garlic, basil, or other herbs?

The original recipe by Marcella Hazan is celebrated for its minimalist purity. Adding garlic or herbs would create a different, albeit still delicious, tomato sauce. We strongly encourage you to try the recipe as written first to appreciate the unique magic that comes from just the three core ingredients.

Why use butter instead of olive oil?

The butter is the secret to the sauce’s signature velvety texture and rich flavor. It emulsifies with the acidic tomato juices in a way that olive oil cannot, creating a uniquely creamy, luxurious mouthfeel and balancing the flavors perfectly.

Conclusion

Marcella Hazan’s 3-ingredient tomato sauce is more than a recipe; it’s a lesson in culinary restraint. It teaches us that complexity is not always a prerequisite for excellence. With a can of good tomatoes, a knob of butter, and a humble onion, you can create a sauce that has graced tables and delighted palates for generations. It is a timeless classic, a perfect embodiment of Italian home cooking, and proof that sometimes, the simplest things are truly the most profound.
