And What Exactly is Au Gratin?
Typically au gratin usually consist of a browned crust which is often topped with breadcrumbs, along with cheese or butter.
In this case I opted to omit the breadcrumbs… although you could add gluten free breadcrumbs if you prefer or even crushed gluten free cracker crumbs.
