Marcella Hazan’s legendary tomato sauce is a masterclass in simplicity and flavor. With just four ingredients—butter, onion, tomatoes, and salt—this classic Italian recipe coaxes deep, sweet, and savory notes from pantry staples. The buttery richness mellows the acidity of the tomatoes, while the onion infuses the sauce with subtle sweetness, then is removed before serving. It’s the perfect sauce for pasta, pizza, or as a base for countless Italian dishes, offering delicious comfort with little effort.

Stir occasionally, crushing the tomatoes against the side of the pan with a wooden spoon.
Simmer uncovered for about 45 minutes, or until the sauce is deeply concentrated and the butter separates slightly.
