Do the pierogis need to be defrosted beforehand or left frozen?
Beth Pierce
The recipe is from frozen. You can let them thaw a bit so they do not all clump together in a huge lump

I live in a small town in Scotland where 99% of folks have never ever heard of perogi. I wish they were readily available in our shops, but alas they are not. I’ve been fortunate enough to taste them once. Your dish looks fabulous, especially today when we’re experiencing our first snow of the season, which has made our roads impassable. If only I could call you up and order some of your perogi casserole for dinner. What would you serve with it? I will just have to content myself with watching the snow fall. After all, it is very beautiful.

I bet it is beautiful. A simple salad always helps balance this casserole out. Or some roasted asparagus or sauteed spinach.
