Here’s what you’ll need to do…


  • 1 can of tomato sauce—when made into a paste, the sauce will reduce to basically half the amount you started with. So, if you have a large 15-oz. can, you can expect 7-8 oz. of paste, and so on.

How to Make Tomato Paste

  • Just throw the sauce into a saucepan. Set the heat on high until it starts to boil. Then reduce the heat to simmer it for about 5 minutes – stirring constantly.
  • It will get nice and thick. Take it off the heat when it’s reached your desired thickness.
