Q. I baked a challah this evening on a baking sheet that had previously been used for dairy (cheese baked directly on that pan). I lined the pan with parchment paper and baked my challah on the paper. The challah did not touch the pan.

Is my challah dairy?

A. On the onset you should avoid baking pareve on a milchig pan, even when lined with parchment paper. After the fact it is considered pareve.
