Notes

Freezing/Storage 
This crab pasta casserole was best when eaten fresh, and warm. You can refrigerate it or freeze it, but it does slightly change the creaminess of the dish. The sour cream is not as creamy when reheated, but it still equally good.
To freeze do not bake the casserole. Assemble it as if you were going to bake it, but do not add the cheese or bake. Store it in a freezer/cook safe aluminum pan covered tightly for up to one month.
To bake from frozen, double the time. I would also probably recommend grating the cheese and adding before baking.
