This trick couldn't be simpler: everything gets combined in one pot until the cheese is melted and the potatoes are creamy. Whole-grain mustard is a surprising flavor upgrade, and sour cream adds a subtle tang. Choose sharp white Cheddar for a rich and decadent flavor, or try Gruyere for a nutty, French rendition. Don’t forget to douse the potatoes with melted butter before serving. Ingredients 3 to 3 1/2 pounds prepared mashed potatoes 8 ounces sharp white cheddar cheese, shredded (about 2 cups) 1 cup sour cream 3 tablespoons whole-grain mustard Kosher salt (optional) 2 tablespoons unsalted butter, melted Directions Combine mashed potatoes, cheese, sour cream, and mustard in a large pot over medium-low. Cook, stirring often, until potatoes are warmed through and cheese is melted, 10 to 15 minutes. Season with salt, if desired. Serve topped with melted butter. Make Ahead Prepare the recipe up to 2 days in advance. Reheat on the stove or in a slow cooker before dinner.
