This easy San Marzano sauce is a classic Italian marinara sauce made with fresh or canned Roma tomatoes, garlic, and herbs. It’s ready in 30 minutes and can be frozen for later!
This summer I planted tons and tons of tomato plants.
At least, it was a lot for my little garden plot.
By late spring, I had twenty tomato plants in the ground, and about half of them were varieties of Roma tomatoes. Most of the Roma plants were San Marzano tomatoes, a large Italian tomato variety.
As the weeks went by and the tomatoes ripened, I got busy!
The juicier tomatoes became tomatoes provençal (baked tomatoes with herbs) and were (mostly) packed away in the freezer for later.
My cherry tomatoes went into this tomato corn salad, onto tomato tarts and focaccia pizza, and were turned into slow-roasted cherry tomatoes (for sandwiches and pasta).
The San Marzanos and other Romas became fire-roasted salsa and mango habanero salsa (for immediate snacking), and were turned into batches of fire-roasted tomatoes (for freezing).
Now, as summer is wrapping up and fall is on its way, I wanted to share an easy San Marzano sauce. This classic Italian marinara can be made with your fresh summer tomatoes or with canned tomatoes later in the year.
Why Use San Marzano Tomatoes for Sauce?
San Marzano tomatoes, as well as other types of Roma and paste-style tomatoes, aren’t juicy.
When you make sauce with juicy tomatoes, you’ll be dealing with a lot more liquid.
San Marzanos also have the perfect flavor for tomato sauce. Their flavor (in my opinion) gets better when cooked, while juicy tomatoes often taste best raw.
Should I Use Fresh Tomatoes or Canned for This Sauce?
For this recipe you can use either.
If you have fresh San Marzanos, use them. This is the recipe they were born to be in!
That said, it’s incredibly easy to find canned San Marzano tomatoes.
If you want, look for the D.O.P. certification on the canned tomatoes. This label ensures that the tomatoes are both the San Marzano variety and were grown in the San Marzano region of Italy, as well as a few other regulations.
I use fresh tomatoes in the photos.
Should I Peel the Fresh Tomatoes?
You can if you want to.
Peeled tomatoes will make a smoother sauce.
Personally, I like a little texture in my pasta sauce, and don’t mind the peels.
If you want to peel your fresh tomatoes before making this sauce, check the recipe card notes for peeling directions.
If you’re using canned tomatoes, they should already be peeled.
How to Make San Marzano Marinara Sauce
If you’re using fresh, unpeeled tomatoes, start by roughly dicing them, and then adding them to a bowl.
For whole canned tomatoes, add them to a bowl and crush them with your hands.
Add a cup of water to the bowl with the tomatoes.
Next, add olive oil and diced garlic to a large, shallow pan. I used this Lodge 12″ carbon steel skillet.
Don’t use a smaller, deeper pan or pot, because the water won’t evaporate as quickly.
Heat the oil and garlic until the garlic begins to sizzle.
You’re not trying to toast the garlic, but if a little bit of the garlic starts to toast it’s okay.
As soon as you hear sizzling, add the tomatoes and water.
At this point, add salt and red chili flakes.
Place a sprig of basil on top of the tomatoes.
As the liquid begins to simmer, it will steam the basil.
Once the basil is wilted, gently push it into the sauce.
If you’re making this sauce in the dead of winter and have zero access to fresh basil, that’s fine.
Use dried oregano instead. Simply sprinkle it in when you add the salt and chili flakes.
Opt for dried oregano instead of dried basil (if possible) because dried basil is much less flavorful than fresh basil, but dried oregano stays flavorful for a long time.
Simmer the sauce until most of the liquid has evaporated and the sauce is thick.
Pull the basil out of the sauce, and season to taste.
If you decide the sauce is too chunky, add it to a blender and blend until smooth.
At this point, you can serve the sauce right away, store it in the fridge for a few days, or freeze it.
Use this San Marzano sauce with pasta (like this scallop fra diavolo), on pizza (like this campfire pizza), or however else you love to use marinara sauce.
This San Marzano sauce is adapted from The New York Time’s classic marinara recipe.

Notes
Canned tomatoes are peeled, and will yield a smoother sauce with less texture. If you’re using fresh tomatoes and want an extra-smooth marinara, you have two options. 1. Peel the tomatoes first. Use a knife to mark an X on each tomato, and then blanch them in boiling water until the tomato peel loosens (~15-30 seconds). Peel, and then proceed with the recipe. Crush tomatoes with your hands instead of dicing. 2. Blend the sauce. After cooking, add the sauce to a blender or use an immersion blender to blend the peels into the sauce. Varieties of tomatoes: San Marzano (as well as other Roma or paste-style) tomatoes are less juicy, and result in a thicker sauce. If using juicy tomatoes instead of Roma, core and seed the tomatoes. You may want to omit the added water (or add less water), depending on how juicy the tomatoes are.
Question: You say use a carbon steel skillet to cook the San Marzano tomatoes. Everywhere I google it says acidic tomatoes will strip the seasoning from the pans even cast iron pans). Did you find this to be true? The suggestions online reccommend teflon or enameled cast iron.
Thanks
Hi John,
I haven’t had any problems with this sauce removing the the seasoning from my carbon steel pan. (If you ONLY use it for acidic foods, that could be a problem eventually I suppose.)
I used my ancient cast-iron skillet, and had a little bit of chicken broth leftover so that went in with the water. The San Marzano tomatoes and basil from my garden were perfect for this deceptively simple recipe. Easy, heavenly, delicious – thank you!
That’s wonderful, Jill! Thanks for letting us know.

I don’t really see the method fo canning the sauce? Just to use or freeze. Is the finish product ready to jar and water bath?
We haven’t tested this recipe for canning, sorry about that!
-Alisha at Champagne Tastes
Doc: If you add 1/4tsp per pint or 1/2 tsp per quart of citric acid to each jar you can water or pressure can them safely.
Can you can this marinara sauce? Or just can the tomatoes to use at another time for making the sauce?
The recipe hasn’t been tested for canning the final product–just freezing! But if you have already canned tomatoes, they can be used as an ingredient.

I made the original recipe one night for dinner – it was an absolute hit.
I have an over abundance of San Marzano tomatoes in the garden this year (could be cause I planted 26 plants lol) but I’ve just taken a recent harvest of 20lbs of tomatoes and made this recipe, and canned them. I did tweak 10lbs and add the rind of Parm to the pot to simmer and it’s just as good- as my youngest says this version is a “mature” sauce (taste wise) lol
That’s a lot of tomatoes!! Glad you enjoyed the sauce, thanks for letting us know.

Do you peel the tomatoes first?
TIA!
It’s optional, so you can definitely do that if you prefer smoother sauce! There are notes at the bottom of the recipe card that may help.

Oh sorry! I didn’t see that. Thanks again.
Our local natural food store had baskets of these this past week so I could not resist. I used our very large cast iron pan, did not peel the tomatoes, subbed coarse dry harissa for the pepper flakes and served it on thick spaghetti. It was delicious! Thank you for the simple recipe.
That’s great! Thanks for letting us know!

My family gives this recipe two thumbs up! My 8 year old says this is the best tomato sauce he has eaten in his entire life and asked for seconds and afterwards asked if there was any left over to pack for lunch the next day! Love the ease of making this sauce as our two Roma tomato plants were very healthy this year! We also love that this sauce freezes well.
Whoa! That’s quite the testimonial! 🙂 Thanks so much for letting us know, we’re happy you all enjoyed it!

I bought 20 lbs of San Marzano from our organic farm co-op this year. I am looking forward to making your sauce, can you share how best to freeze it, including what type of containers to use.
Thank you!
Thanks for getting in touch, Georgia! We hope you love this sauce.
To freeze the sauce, just start by letting it cool completely. For containers, I know some people swear by Souper Cubes silicone storage molds with lids. We usually store ours in 1-quart freezer bags or glass jars. If you use glass, make sure to leave headspace at the top of the jar for expansion when the sauce freezes.

I was thrilled to find this simple sauce recipe to use the San Mariano’s from my garden. We love garlic, so this sauce is an absolute hit. Right now, I’m cooking up are fourth batch, and I think I’ll have enough tomatoes for one more before I need to switch to cans.
This is honestly the first sauce I’ve ever made, and it is so easy. I’ve tried subbing chicken stock for the water, and it still tastes great. Thanks for a true keeper recipe!
Yay! I’m so glad you enjoyed! 🙂
