Heat oil in a large skillet on medium heat. Add onions and cook for 6 mins stirring often. Add the minced garlic, thyme, rosemary and oregano and cook until fragment. About 1 minute. Turn heat off. Add onions, garlic, crushed tomatoes, rosemary, thyme, oregano, parsley, salt and pepper to a blender or food processor and blend until completely smooth. Add sauce back into the skillet and heat over medium heat. Add in bay leaves. Bring sauce to a low boil stirring often to prevent burning. Once sauce reaches a low boil, turn heat down to low and place a lid over the skillet. Simmer for one hour, stirring occasionally.
