Lasagne for tomorrow

[couldtryharder]

Got friends coming for lunch tomorrow and am doing a bit lasagne. To save time as tomorrow is a bit full on with kids clubs first thing, I have made the ragu today. Can I then put the whole thing together today to bung in the oven tomorrow? And if I do should I wait til the ragu and white sauce are cold? Worried the pasta will start to curl up if it's hot. TIA.

I would put it together tomorrow as it can curl up

How are you storing the white sauce? To make sure there's no skin put some cling film on the top if it's a bowl type container but a freezer bag is best cause then you can just snip a corner off and use like a piping bag

Cook today and reheat tomorrow. I find lasagne best on the 2nd day

I prefer lasagne the next day - the flavours merge together more - if you put enough sauce on to cover it all it shouldn't curl up.
