  • 1 28oz can San Marzano Tomatoes
  • 5 tbsp butter
  • 1/2 medium yellow onion


  • Place tomatoes, butter and 1/2 of an onion (peeled, but do not chop, just sit the entire half in, cut side down) into a medium to large heavy bottomed sauce pan. Heat over medium until tomatoes start to bubble. Then reduce heat and simmer on low.
  • Cook, stirring every 10-15 minutes.  The sauce is done when the butter has separated from the tomatoes and there is no remaining liquid.
  • Remove onion (you can save to reuse if desired). If desired, use an immersion blender to blend smooth. Serve immediately.
