Hi Barb,
It's been a while since I made oven roasted tomato sauce, but I do remember how nice the kitchen smelled! As I recall I believe I set the oven to 400F and roasted them until the skins began to caramelize. My oven at the time tended to read low, so the temperature may have been as high as 425F.
I haven't grown paste tomatoes for a while, but decided I will next year and put up some roasted sauce.
