Tomato Sauce with Butter and Onion


  • 2 (28oz) cans whole plum tomatoes (try to use best quality, if you can)
  • 7 Tbsp butter
  • 1 medium sweet onion, peeled & halved


  1. Add tomatoes and their juices to a large saucepan. Add butter and onion. Cover and bring up to a simmer. Simmer over medium-low heat about 45-50 minutes, stirring often. Break up tomatoes with your spoon as you stir.
  2. When ready to serve, remove onion and discard (or, you can mash it up and stir it back into the sauce if you like). Serve over pasta.
