Liberally brush an oven safe saute pan with butter. Arrange a layer of potato slices in concentric rings. Lightly brush the potatoes with butter and season with salt and pepper. Continue making layers like this until all the potatoes are gone.
Place the saute pan on the stovetop and cook undisturbed over medium heat until golden brown on the bottom, about 4-5 minutes. Transfer the potatoes to the oven and cook until caramelized and cooked through, about 30 minutes, shaking the pan periodically to keep the potatoes from sticking to the bottom. If top layer hasn't browned by the time the potatoes are tender, raise heat to 450 and continue to cook until golden, checking often.
To serve, drain any excess butter, place plate over pan and invert (so the bottom becomes the top). Cut in wedges.
