How long to cook a tagine in the oven?

I have a clay tagine pot that's meant for the oven. If I put raw meat in it with spices and vegetables, how long should it cook in the oven?How long to cook a tagine in the oven?
I usually pre-brown the meat and cook for about 45 minutes to 1 hour. Chicken after 45 min and Lamb about 1 hour in the tagine.
Mark is right, I use mine in a low set oven around 325 d F for 1-2 hours depending on the meat or veg I use, because of the lid you do not need to stir or worry about it boiling dry, I just brown the meat, add the veg, pickled lemons and spiced broth, I have Ras el Hanout for the real flavour, Harissa pepper paste if you like a spice dish to is good in the beginning.How long to cook a tagine in the oven?
until golden brown. Or just stick a tooth pick in it, and if you take it out and it has goo on it, it's not done.
Tagines are made for low temp slow cooking so I cook mine for about 2 hrs at 300 degrees, it may need longer for bigger cuts of meat.
till it is golden brown...
