That looks very good, and different!
re: Oyster casserole - Oh that brought back memories! My grandfather grew up in St. Elmo, Illinois. Came south in the 1920’s and saw my grandmother and married her. :-) I don’t know if that’s where our oyster casserole tradition came from, but we always had that at Thanksgiving and Christmas when they were living. I don’t think I’ve ever made it.
I grew up in Canada and I forgot about this dish we always had on holiday table. Thanks for posting. I will make it this season for sure.
