1 pound Yukon Gold potatoes, peeled and cut into 1 inch cubes
2 teaspoons salt
Preheat oven to 400º F.
Place potatoes in a large cast-iron skillet and pour in enough hot water to cover about 1/4 inch of the potatoes.
Scatter bits of butter over potatoes and season; then stir.
Bake uncovered about 60 minutes, until potatoes are lightly browned and water has evaporated.
