Every person who makes a homemade version of scalloped potatoes usually has had that recipe passed down to them from their mother, their mother’s mother or even further in their history, so the emotional attachment to the recipe immediately precludes any other scalloped potatoes from contention.
At an early age, I remember my mother ‘teaching‘ me the art of making scalloped potatoes. It came down to very thinly sliced potatoes sprinkled with flour, salt & pepper then covered with scalded milk and baked. I think it was dotted with butter and quite possibly topped with bread crumbs. For that matter, there might have even been a few thinly sliced onions involved but I have to admit, I’m a bit fuzzy on that. As plain and simple as it was, it tasted glorious to us.
This scalloped potato recipe starts with Yukon Gold potatoes. They have loads of great flavor and are a beautiful color both when they are raw as well as when they are cooked. For this particular recipe, keep the skin on the potato as it will add loads of fiber to the dish.
Food trends come and go and nothing highlights this more than looking up old recipes. Still eaten today, scalloped potatoes were the prolific side dish of the 1920s. Dairy was no longer rationed and the rich casserole took full advantage of this.
