Roasted San Marzano Tomatoes are incredible, if you get your hands on these fresh beauties. You’re in for a real treat. Trust us.
What are San marzano tomatoes?
Our obsession with growing heirloom tomatoes is obvious. Over the years we’ve grown so many different varieties except for the San marzano variety. They’re a popular plum tomato originating from the rich volcanic soils of Italy. These tomatoes are highly prized for their sweet, intense tomatoey flavor and not too much acidity. When compared to other plum tomatoes like the Romas, the San marzano is slightly thinner, longer and pointed at the bottom. Their flesh is also thicker, plump and meatier which adds to their amazing flavor.
Intense roasted flavor
When these gems are roasted the flavor is absolutely incredible. Rich, flavorful and sweet flavors in every bite is intoxicating. In fact, it’s so good that a fresh roasted san marzano tomatoes batch never makes it to sauce. We keep sneaking in bites and snacking on them that they just end up eaten by the end of the day. There’s a reason why these tomatoes are prized for making sauce! So the reality is that if you do decide to make sauce, buy or grow extra. Once you start roasting them, you’ll need an extra batch to make it to saucing.
Enjoy!

Roasted San Marzano Tomatoes from Canned Tomatoes
Yes, it does work and taste pretty good if you roast the canned san marzano tomatoes! Results are little more watery because they’ve been soaking in juices. But the flavor is still excellent and a great way to have a snack or a side dish to your grilled dishes. Left photo shows the canned tomatoes. Right photo shows them roasted.

San Marzano tomatoes are perfect for roasting. The roasting concentrates the flavors, and the normally flavorful san marzanos will become even more so. And if the tomatoes aren't straight-up amazing before roasting, the roasted tomato sauce will give you a ton of the flavor that you're looking for.
For the roasted tomatoes, you can also use any plum or paste style tomato varitey like Roma tomatoes.
If you have a Roast function on your oven, go ahead and use that mode. Just make sure to adjust cooking times a little less. Roast the tomatoes to your preferred darkness.

Found some fresh San Marzano tomatoes at our farmers market in Mexico and tried your recipe. You are correct, I should of made two pans. One to eat immediately straight off the pan and the other to make a sauce. LOL Delish! Can’t wait to find them again!

What do you do with the garlic cloves?
-

Hi Larry,
The garlic gets added to the tomatoes in step 2. Everything is roasted together and used together, whether it is with the simple roasted tomatoes or if you make it into a sauce. Also, if you aren’t a fan of garlic, you can always omit them.
Enjoy!

I have made these roasted San Marzano tomatoes several times and the recipe is perfect! I use fresh tomatoes rather than canned and they are a winner every time!

This is inspiring! I have 2 good sized San Marzano plants growing now. The appear to be growing a bumper crop this year. I’ve roasted mine sor sauce but I roast them very slowly at temp of 250. I also add some finely grated carrots to tame any acidity. I crave them in the winter but we go through them quickly! Thanks for the inspiration!

After roasting .. can I vacuum seal and freeze the roasted tomatoes for using this winter with meals??

Hi Charlotte, yes you can. Just make sure to freeze the tomatoes first in the bag, then vacuum seal. If you do it while the tomatoes are fresh, you might suck out all the juices.

Hello… I am so interested in making these and I have a whole bushel of tomatoes…. Can I freeze the extras in freezer bags without vacuum sealing?

OMG! Just made your recipe for roasted San Marzano & Garlic sauce. It is by far the best tomato sauce I have ever had! So easy and delicious. Used the roast function on my convection oven as recommended. Now I can’t wait for more San Marzano tomatoes to ripen in my garden so that I can make some more. Thank you!
