I do the same with lasagne make two or three and when assembled but not put in the oven I freeze them so I can defrost and cook and it tastes like fresh!
Lots of leftover portioned meals. I deliberately cook extra each time I do something that freezes well so I can have a lazy night and not cook sometimes while on maternity leave! When Im working I do afternoons and take one with me and defrost the rest for kids and DH
