Line a 9×13 baking dish with foil. Pour one bag (5 oz) of crushed potato chips onto the foil.
Combine the barbecue sauce and the melted butter (it’s okay if the butter isn’t all the way melted).
Dip the salmon pieces in the barbecue sauce mixture. Place the salmon on the chips. Pieces will fit tightly next to each other. Cover with the remaining crushed chips.
Cover the pan with foil and bake for 10 minutes. Uncover the pan and bake for additional 15-20 minutes, until the fish flakes with a fork.
Let cool for a few minutes before serving.
