We're hosting a party in a few weeks and I'd like to make some things ahead of time. Namely I want to make pasticcio. Usually I make the meat sauce the day before. Then the day of I boil the noodles and make the bechamel sauce, construct and cook a few hours ahead of the party. The pasticcio needs to be served warm, not hot, not cold, not room temperature. So my question is, can I get away with making it the day before and reheating it in the oven? So which of these options would be best? 1. Construct the pasticcio - layer the cooked noodles, meat sauce and bechamel and stick it in the fridge. Cook it the day of the party. But will that make the bechamel weird? 2. Cook the whole thing the day before and reheat the next day - but would that alter the creamy texture of the bechamel? 3. Continue as I have by making the meat sauce the day before and the rest on the day of the party?
