How to Freeze Italian Tomato Sauce It’s really easy to freeze this sauce. Allow the sauce to come to room temperature. Then put it in an airtight container (or a large zipped lock freezer bag) to chill in the refrigerator.
Can I use canned tomatoes ? I typically buy San Marzano DOP. It’s important that you read your canned tomato label. If you can hunt down Pomodori San Marzano dell’Agro Sarnese-Nocerino, DOP, from the region of Campania. They are authentic and the BEST. They have less seeds and also, are naturally sweet. You could look for tomatoes in a can, jar or even a carton.
