Pre-heat oven to 350°.
Toss the potatoes generously in the Special French Dressing, making sure to get all of the slices nicely coated.
Sauté the potatoes in the butter in a medium-high oven-safe skillet until they are nicely golden brown.
Place skillet in oven (or transfer potatoes and all of the butter and juice to a baking dish).
Bake for about 30 minutes or until potatoes are tender.
For added flavor, baste the potatoes with a little of the dressing about halfway through.
