Make-ahead mashed potatoes are a great option for the holidays. You can do nearly everything — boil, peel, and mash; stir in milk and salt — up to two days ahead. Before serving, reheat. Adding butter at the last minute makes them taste freshly mashed.

Ingredients
3 pounds russet (Idaho) potatoes, scrubbed but unpeeled
1 ½ cups half-and-half
salt to taste
6 tablespoons butter, softened
Directions
Place potatoes in a large pot and cover with salted water; bring to a boil. Reduce heat to medium-low and simmer until tender, about 20 minutes. Drain.
Heat half-and-half in the microwave until just warm.
Process unpeeled potatoes through a food mill into a medium bowl. (Or, using a potholder, peel and drop them into a bowl. Puree using a potato masher or stand mixer fitted with the paddle attachment.) Stir in warm half-and-half and salt (or beat, if using a mixer) until smooth and fluffy. Cool, cover, and refrigerate potatoes in a microwave-safe, airtight container for up to 2 days.
Thirty minutes before serving, microwave until warm. Transfer to a heatproof bowl set over a pan of simmering water. Stir in butter to melt. Cover and keep warm.
