Pre-heat oven to 400 degrees.
Add mayonnaise, Parmesan cheese, honey dijon, and white balsamic to a small mixing bowl; whisk until combined and taste for seasoning. Set aside until ready for serving.
Thinly slice each potato without cutting all the way through and place it on a baking sheet. Melt the butter in a small mixing bowl and add olive oil, garlic, parsley, onion powder, salt, and paprika. Stir until combined. Baste each potato with the mixture, reserving approximately half. Bake potatoes for 20-25 minutes. Remove from oven and baste again. Bake for an additional 20-25 minutes until golden brown and crisp. Sprinkle with chopped chives and serve with Parmesan Honey Mustard Dipping Sauce. Enjoy!
