This is a dish that hearkens back to 1980s vegetarianism, when I started making it. From the 1983 Nikki & David Goldbeck's American Wholefoods Cuisine. It is basically Spinach au gratin, with the addition of cottage cheese and noodles. It is unlike most recipes I've found that call themselves Spinach Noodle Casserole because it lacks the white sauce (Béchamel sauce) used in most American casseroles to bind everything together. The recipes that are most similar end up being Ukrainian. It is very simple, with nice contrasts between the flavors and a wonderful buttery crumb topping. Unfortunately, I have been unable to locate gluten-free flat egg noodles. Macaroni or rotelle or shells work, but are not as good as the egg noodles were. Next time I may try the fat Thai rice noodles to see if they are any better.
