The classic dish of lyonnaise potatoes is named after the city of lyon, in france. This french dish requires lightly boiling sliced potatoes before sauting in butter with lightly caramelized onions. The potatoes are finished with fresh chopped parsley. Alternatively, the potatoes can be baked in the oven. Slice the potatoes into rounds nearly 1/2-inch in thickness so they will not fall apart easily as you saut and turn them. For cooking, a nonstick or seasoned cast iron skillet are good choices.
