  • 5 pounds tomatoes
  • 1 onion peeled, chopped
  • 1/4 cup olive oil
  • 1 tablespoon salt or more to taste
  • 1 teaspoon freshly ground black pepper or more to taste
  • fresh basil
  • 2 tablespoons butter optional
  • 1 tablespoon honey or sugar optional


  • Cut a x on bottom of each tomato (to be able to peel).
  • Put into boiling water, just enough to fit, usually 4 - 6 at a time. Once water is boiling again, cook for about 8 seconds. Remove. Cool.
  • Peel tomatoes.
  • Hold over a bowl and squish a little bit to get some liquid out of the tomatoes. No need to remove all, but some tomatoes have more water than others.
  • Chop roughly, put in slow cooker.
  • Add onion, salt, pepper and basil.
  • Cook for 6 hours on low in slow cooker or 2 to 4 hours in a pot on stove. The important thing is to reduce a lot of watery liquid from the tomatoes.
  • Taste sauce and adjust for sweetness and salt and pepper.
  • Blend with immersion blender or blender.
  • You may choose to add in some butter and stir to make a very smooth sauce after you have blended it.
