San Marzano Tomato Sauce is made with just a few ingredients to let those special tomatoes be the shining star. You can make it with fresh or canned tomatoes and use it lots of ways!
Exactly what are San Marzano tomatoes?
San Marzano is a type of plum tomato that is considered the crown jewel of the tomato world. They have less seeds, are sweeter and less acidic than other tomatoes.
According to our friends over at Martha Stewart you will want to look for the Italian “DOP” designation on the tomato can. This refers to the Protected Designation of Origin. It assures that your tomatoes were grown in the designated region of Italy between Naples and Salerno known for this special crop.
Widely available in the U.S. and a favorite of ours is the Cento Brand. They have taken the origin of their tomatoes a step further. With Google Earth and the lot code on the can you can “Find My Field” and pinpoint the exact field where your tomatoes were grown!
However, seedlings and seeds are now widely available in the U.S. and San Marzano tomatoes can be grown here. They just won’t have the DOP designation.
That’s, in fact, how I got curious about the variety for this San Marzano Tomato Sauce. We grew some of the tomatoes in our garden this year and I wanted to know the details to share with you.
How to prep the tomatoes if you start with fresh
Starting with ripe, clean tomatoes you’ll first dip them in a pot of boiling water for about 45 seconds to 1 minute. Cool them off with a quick dip in a bowl of cold water. You could even rinse with cold water in a colander in the sink.
This process will make them easier to peel. I make a small cut with a serrated knife to give a place to grab the edge of the peel. It should come right off.
I like to trim off the very top of the stem end, but you can leave them on. It’s your choice. Then coarsely chop them and put in a sauce pan over medium low heat.
Once the tomatoes get good and hot you’ll want to stir occasionally and “stew” them for about an hour. At this point you’ve got fresh tomatoes similar in form to what you can buy canned.
Canned or fresh tomatoes take one additional step of preparation

The tomatoes for your homemade San Marzano Sauce will need to be further chopped or pureed. The choice is yours as to how smooth or chunky you like them.
Our preference is to still have little pieces of tomato. We do this with a few pulses in a standard blender. You could also use a food processor and pulse it to keep chunks or leave it going to make your sauce smooth.
An immersion blender is another choice, but that’s only good if you make it in a deeper pot. Of course you could blend your tomatoes in a pitcher or deep bowl and then transfer them.
We like making this sauce in a skillet to get more liquid evaporation. It keeps your San Marzano Sauce naturally thick from the tomatoes themselves.
Keep San Marzano Tomato Sauce simple
These tomatoes are the star of the show and you don’t want to overcomplicate your sauce. Too many additional flavors will begin to hide the main event.
Basil is the only herb we used. If you’re someone who thinks a good homemade tomato sauce must have oregano, then by all means, add some, but keep it light. We had fresh basil and just simmered it in the sauce whole and removed at the end.
If you don’t have fresh herbs you can certainly use dried ones, but again – use a light hand when adding them.

Can this sauce be frozen?
Pam says
Charlotte, We have not tested freezing it, but I see no reason it couldn’t be.
Don N Pat says
What are your thoughts if we were to want to “water bath” can this sauce? Any suggestions or hint’s? Anyone?
Pam says
Hi there!
Canning is not in our wheel house, but I feel sure it would be fine to “water bath” can like any other similar tomato sauce. Maybe another reader can chime in, but a quick Google search should reveal some good sources too. Thanks for stopping by!
Sue says
We have been water bath canning tomatoes for generations. May I suggest from past experience, we do not can the seasoned sauce. The tomatoes are prepared and put up with one TBLS ACV and one teaspoon of uniodized salt per quart. The flavor of the fresh seasoned sauce using Pam’s recipe is delicious and the unseasoned canned tomatoes can be used in other recipes, soup, gumbo, okra & tomatoes, gravy, tomato pie and more delicious recipes using tomatoes from Pam & Sara.
Pam says
Thanks so much, Sue. We love it when our readers help each other out. One question I have for you, though. What is “ACV”?
Sue says
Apple Cider Vinegar (Bragg’s Organic)
Jane says
This was really delicious. I used Cento whole tomatoes, followed the ingredients as listed, and used the immersion blender at the end of 4 hours cooking. Served over Angel hair pasta. We are having this again tonight! Great recipe!
Pam says
Yay! Thanks so much for letting us know!
