While wrapping Christmas presents this year, I tuned into America's Test Kitchen, and caught them making these gorgeous potatoes. The words they used to describe them was Spanish, and I have no idea what it actually was -- but I put these potatoes together that night and they really are quite lovely.
2 lb. Yukon Gold potatoes peeled and sliced about 1/4" thick
1 medium onion sliced
Salt
3 T. Olive oil
1/2 c. white wine
Combine potatoes, onions, olive oil and salt in a bowl, mix well to cover (don't be afraid of the salt, be liberal in its use)
Transfer to a 8x10 baking dish, cover tightly with foil and bake for 45 minutes in 450 degree oven.
After 45 minutes, remove foil and pour wine onto potatotes. Return the pan with foil on top (but no longer tightly sealed) to oven for another 15 minutes
Voila! Easy Elegant Potatoes.
