This is definitely a make-ahead recipe. The dough needs to “rest” for three days (sounds more like a vacation than a rest, to me!)
Soft in the middle and crunchy on top, this comforting breakfast dish is part strata and part pudding. The ham lends an alluring smoky taste, while the Gruyère, an excellent melting cheese, adds a slightly nutty note.
In this twist on the classic quiche Lorraine, a crust of hash browns stands in for the usual pastry. The whole thing’s cooked in a large cast iron skillet to give the potatoes a nice, crispy, golden brown finish.
