Total Time:
1 hrs 10 mins
Serves 8 (serving size: 1 cup)


  • 1 1/2 cups yellow onion, chopped

  • 5 cloves garlic, chopped

  • 2 28 oz. cans San Marzano tomatoes, undrained

  • 8 tablespoons unsalted butter, cut into cubes

  • 1/2 cup fresh basil, chopped


  1. Heat 1 tablespoon olive oil in a large saucepan over medium high heat. Add onion and garlic and cook 4-5 minutes, stirring occasionally, until onions are softened but not browning. Add tomatoes and stir to blend. Once mixture comes to a low boil, turn heat to medium low and cook 45 minutes, stirring often, until tomatoes are breaking down and sauce is thickening.

  2. Use a potato masher to lightly crush any whole pieces of tomato but leave some texture in the sauce. Add butter cubes to sauce, stirring constantly until all the butter melts. Season the sauce with kosher salt to taste and stir basil in when ready to serve.
