Can you assemble lasagna one day, and then bake it about 24 hrs later? I've always made it on the spot and cooked it then and there, but would like to make at home and take it to a large party the next day and cook it then - will it work?
Yes, and I find it taste better.  When I make lasagna I will not fully cook the pasta.  Instead, I keep a pot of boiling water and I dip the pasta into it to soften while I'm assembling the dish; the pasta is in the water for less than one minute.  The pasta seems to absorb more of the sauce, keeping the flavor but making a dish that does not fall apart as easily.
