It's a go-to dish when I wake up to a note on the table saying one of the kids has a friend sleeping over. We usually have a can o'biscuits in the fridge, and something to enhance them.
Bake. It takes about 20 - 25 minutes in a 350F oven; it depends how deep the layers are in the pan. More layers, more time, and lower temp, otherwise doughy in center and burned on top.
