Simple, classic and downright magical, this iconic tomato sauce by Marcella Hazan uses just 3 ingredients and it shows less is better. With just tomatoes, butter and onion, it turns pantry staples into a rich and silky sauce you will do it repeatedly.

Why this sauce earned its fame
- A breeze to cook:Just three basic points come together to create a sauce with great depth. The butter melts into the tomatoes for a smooth, rich sauce.
- A clever shortcut:The onion cooks halved, adding flavor without being cut, then removed to leave a silky, delicate sauce.
- Endless ways to use it:Toss with pasta, spoon on meatballs, add a layer of lasagna, spread on pizza, or freeze for quick dinners later.
Ingredients of Marcello Hazan’s tomato sauce

- Canned Tomatoes: Use canned tomatoes without added salt or herbs. Cento San Marzano is a great brand!
- Onion: Use a white or yellow onion!
- Butter: The original recipe calls for unsalted butter, but if you only have salted butter, it will work.
