Step 1

You'll need extra butter and cream, along with your finished mashed potatoes.

Step 2

Butter the slow cooker and add extra cream. Butter the insert of the slow cooker. Drizzle a small amount of cream in the bottom.

Step 3

Keep warm on LOW for up to 4 hours. Transfer the mashed potatoes to the slow cooker, and set to LOW. Keep warm for up to 4 hours, stirring once an hour.

Step 4

Stir before serving. The mashed potatoes will stay warm and creamy. Keep stirring in any cream that separates out; you may find that the potatoes get a little thinner as they sit.
