As I mentioned in 9-12: Shepherd’s Pie, I had a LOT of potatoes to get rid of after buying too many at Costco. So here’s another potato recipe for you: 6-30: Scottish Chicken Casserole.
Offhand, I have no idea why it’s “Scottish”, other than it seems similar to a lot of food you get in the UK. A cursory Google search turned up this recipe, which seems kind of like this one. This other recipe (from the same search) gives a bit more history, linking it to a classic French (and Scottish) casserole-type dish.
