    • Hi Elicia,

      I can’t see any reason why it couldn’t be canned – it also freezes well if you want to keep some on hand for a quick defrost.

  1. I just made this tonight! It is amazing and delicious! Thank you, I will be using it as a keto pizza sauce as well. We loved it, taste so much better than the jar. I used dried oregano and thyme 1tsp each and still came out fabulous!

  4. Wow this sauce is amazing! I used one can of diced tomatoes in place of some of the tomato puree as I like a little ‘chunk’ to my sauce. The flavors are awesome and it is so easy to throw together. This is going to be a staple on my menu. Thank you = )
