Make-Ahead Slow Cooker Mashed Potatoes

Place potatoes into a large pot and cover with salted water; bring to a boil over high heat. Reduce heat to medium-low and simmer until fork tender 20 to 25 minutes. Drain water and place pot with potatoes back over medium heat until potatoes are dry 1 to 2 minutes.

Mash potatoes using a hand mixer until smooth. Stir in cream cheese half-and-half egg whites chives onion powder salt and pepper. Blend well.

Spray a slow cooker insert with nonstick spray and add mashed potato mixture. Cut 1/2 cup butter into tablespoon-sized pieces and add to potatoes.

Cook on Low for 2 1/2 hours stirring once or twice during the cook time. Stir in remaining 1/4 cup of butter 1 tablespoon at a time and cook for an additional 30 minutes.
