Tomorrow night we are having friends over for food, drink and basketball. I plan on making a baked ziti and serve salad and bread to go along with it. My ziti is always about 90% there, but misses the mark every so slightly. I use sausage, make a tomato sauce, mix fresh mozz in it and on top. I usually bake it at about 400 for 30 minutes. Should I cover it when baking until the end? Add ricotta? Lower temp? Bake then broil?
