Pour both cans of tomatoes into a fine mesh strainer set over the sink or a bowl. Let the excess liquid drip off for a couple of minutes – this step is what gives you a thick, spreadable sauce instead of a watery one.
Add the drained tomatoes, tomato paste, sugar, garlic, dried oregano, dried parsley, dried basil, and salt to a blender or food processor.
Blend on high speed for about 30-60 seconds, until the sauce is completely smooth and a deep, rich red colour. Stop and scrape down the sides if needed.
Give the sauce a taste and adjust the salt, sugar, or herbs to your liking.
Use immediately on your favourite pizza, or transfer to an airtight container and store in the fridge or freezer.
