Has anyone tried to cook in advance and freeze?

I have been making scalloped potatoes for decades (but not this particular recipe since I don't make this using a recipe) and I have never found the defrosted ones to be as good as the freshly made ones. Edible yes but certainly not the same quality.

However some people are less picky about quality degradation. Try it out and decide for yourself if A.) it's something you'd eat yourself as leftovers during a busy workweek, and B.) whether or not it's something you'd put in front of dinner guests.

In the end you just need to please the taste buds of those sitting at your dinner table.

Best of luck.
