Tough question to answer. So many variables....
It cooks in a short period of time, and it's done once the pasta is tender.
I'd go 350 degrees in the beginning...and take some away while simmering.
This is best explained here:

Really, it's a judgement call or a rule of thumb guestimate.
Me, on this recipe using my 12" oven...I'd light about 15-20 coals...and use them on the bottom only. (lid not needed)
This recipe is good to use stovetop as well.
