Chop and dice fresh ingredients
Add the olive oil, onion, garlic, and herbs (sage, rosemary, and thyme) sea salt and freshly ground pepper to a saucepan and sauté them until they become soft and fragrant. This will take about 5-10 minutes.
Once the onions and garlic are soft, add the fresh cherry tomatoes, fresh mushrooms, salt, and pepper simmer the sauce until it thickens and the flavors meld together. This will take another 5-10 minutes.
Add the canned, whole San Marzano tomatoes and vegetables and allow to simmer on medium-high. This will take 5-10 minutes for the flavors to infuse. You should be smelling wonderful aromas at this point!
Once the sauce has simmered for a period of time and the vegetables have softened, remove the saucepan from the heat and allow it to cool slightly before transferring it to a high-speed blender. Blend the sauce on high speed until it reaches a smooth and creamy consistency – only about one minute. This step can help to break down any remaining chunks of vegetables and create a velvety texture.
After blending, the sauce can be transferred back to the saucepan and simmered for a few more minutes to thicken and allow the flavors to meld together with reserved sauce base. Stir until completely combined. This technique makes a smooth homemade pizza sauce with some texture and body!
