How Long for Lasagne in the Oven?

[FrockHorror]

Have made the lasagne but need to know how long to cook it for in the oven? Is there any chance I can have DD in bed by 7pm??

TIA!

about 40mins at 180

If everything is cooked then about 20-25 minutes to heat through and melt the cheese on top.

yes mine only takes about 40 mins

Ok, I cooked all the mince, mushrooms, onion, tomato and layered it up with dry lasagne sheets. The oven is on at 200. So I am looking at about 40 mins?

I usually cook at about 190 for 25 minutes with foil on and then another 10 minutes with the foil off.
