Potatoes are probably the national vegetable of Denmark. In fact, every year every Dane consumes on average 73 Kg potatoes (160 pounds). Potatoes au Gratin is one of our favorite ways of cooking potatoes, and one of the few ways that Wendie actually likes. It is of course a rather creamy affair, so we don’t do it very often. Recently we indulged ourselves, which left us with a bit of leftovers. Undaunted by the scornful look from Wendie, I went ahead and created this little beaut, a potato au gratin sandwich. What’s not to love when it comes to starch on starch?
Optionally: Add 3 tsp butter, spread out on top before baking.
Slice the potatoes into 1/4 inch thick slices. Lay them out in a casserole. Mix everything else together and pour over the potatoes. If the cheese stays on top then mix it in. Place casserole in the middle of a pre-heated oven at 400 degrees for 45 minutes. If the potatoes starts getting burned, turn oven down to 450, and cover with aluminum foil. Leave them an additional 10 minutes in that case. We have a very bad oven, we know.
