Prep time: 15 min

Cook time: 45 min




  • 10 pounds tomatoes, cored and quartered (this does not need to be exact, just fill up your stock pot nearly to the top)
  • 2 medium onions, quartered
  • 1 head of garlic, cloves peeled
  • 1 tablespoon salt



  1. Place all ingredients in a large (approximately 8 quart) stockpot.
  2. Stirring occasionally, cook on medium heat until garlic and onions are softened and sauce has reduced about 45 minutes.
  3. Pureé with a stick blender until smooth.
  4. Pour finished sauce into canning jars and seal or pour into freezer-proof containers to freeze the sauce.



If you're daring, add an habañero or other spicy pepper to the mix for a slightly spiced sauce.
Sauce can be canned or frozen.
