The best thing about this risotto is that no, it doesn't need to be served immediately. While it certainly is delicious served up straight away, it also reheats wonderfully making this one of my favourite things to make for meal prep. I like to enjoy it once as a cozy dinner and then the rest for lunches throughout the week. You can also keep freshly baked risotto warm covered in the oven while turned off for up to an hour before serving.
