I was researching gratin recipes when I created the Potato and Three Onion Gratin. There are a lot of definitions of what a gratin is but basically it’s almost any recipe such as this one that’s baked after having been topped with bread crumbs or cheese (or both). The sweetness of the scallops works great with the savory, umami taste of the mushrooms. The breadcrumbs and cheese add an almost decadent richness to the dish.
This recipe is safe for Coumadin (warfarin) users as well as those with GERD / Acid Reflux. This recipe is safe for those who are lactose intolerant, but those who are gluten-sensitive should avoid it.
