How long to cook large lasagne from fridge

[QueenLagertha]

Catering DSs christening this evening ourselves. Made lasagnes last night and have In fridge. DH just mentioned he thinks they'll take an hour to cook from the fridge. Will it make much difference if I take them out of the fridge before we leave? The service will likely only take an hour and we live close to the church.
Don't want everyone sitting around waiting ages on food.
DH has suggested covering them in foil and putting in oven down low before we leave but I'm afraid of drying them out.

Suggestions?

It isn't particularly hot weather, so I think it will be fine if taken out of the fridge while you're out and then put straight in the oven when you get back.

I wouldn't bother taking them out of the fridge. I'd cook for 45 minutes + (depending on the size of your lasagne), just check it's piping hot in the middle before serving!

To add:

An hour out of the fridge won't make much difference.

And

I would be worried about drying out if you cook on a low temperature (plus the risk of leaving an unattended oven, although I suppose plenty of people do this when they go to church on Christmas day)!

An hour sounds right. I cooked a large lasagne yesterday and that was the cooking time.

Thanks all
@RudsyFarmer did it dry out much

Tried to make mine really saucy to compensate for being in the fridge overnight. There's nothing as disappointing as a dry lasagne!!

Should I cover it with foil for first half hour?

It was very slowly but just the right consistency when cooled.

Sloppy

I would cover with foil for 45 minutes.

Thanks all. I didn't get back to the thread. Just bunged them in the oven uncovered. They weee in nearly an hour. Came out perfect. Everyone was raving about how nice they were

@RudsyFarmer mine were slightly sloppy too, just the way I like it. Leftovers will be perfect today
