Arrange a rack in bottom third of oven. Preheat oven to 425°F. Line a rimmed baking sheet with aluminum foil and coat with nonstick cooking spray.
Mix bread crumbs with soup mix, paprika and pepper in a shallow bowl. In a separate shallow bowl, combine mustard and 2 Tbsp. water. Spread flour on a plate. Dredge pork chops in flour. Coat both sides of each pork chop with mustard mixture, and then dredge in bread crumbs to coat well. Place chops on prepared baking sheet.
Drizzle 1 Tbsp. melted butter over each chop. Bake until cooked through, 10 to 15 minutes, turning chops over halfway through cooking time for even browning. Let chops rest for 10 minutes before serving.
