Up your potato game! Perfect for New Year's Eve celebrations! Duchess Parmesan potatoes are wood-fired, kissed potato piles of deliciousness. Worth it to pipe them out and get the crispy bits for an elegant dinner.
In a large bowl, mix the mashed potatoes, salt, pepper, Parmesan, softened butter, and egg yolks until well combined. Place the potato mash into a piping bag fitted with a star tip. Pipe swirls of mashed potatoes onto two silicone-lined baking sheets. Refrigerate for a minimum of 2 hours or overnight; you want the potatoes to be cold when they go to the grill so they hold their shape. Preheat your grill to 400F. In a small bowl, mix the melted butter with the Traeger chicken rub. Place the trays with the piped potatoes on the grill for 20 minutes. Drizzle the potatoes with the melted butter mixture and continue to grill until lightly browned, approximately another 10-20 minutes. The exact time depends on the potatoes, so check every 5 minutes. Serve with your favorite meats and vegetables!
