Mashed potatoes hold best when they are made fully, cooled quickly, and reheated with gentle moisture instead of being partially cooked and finished later.

For the best texture:

  1. Make the potatoes through the seasoning step.
  2. Spread them in a shallow dish so steam escapes quickly.
  3. Cover and refrigerate once they stop steaming.
  4. Reheat over a double boiler or low burner with milk, cream, or butter folded in gradually.

If you need to hold them for service, use a warm slow cooker on the lowest setting and stir in extra fat before they start looking dry.
