Crockpot mashed potatoes are the easiest mashed potatoes ever! No need to deal with a pot of boiling water or drain the potatoes! They just cook themselves in a crockpot :) Once you try making mashed potatoes in a slow cooker, you'll never make them any other way!
Put potatoes in a slow cooker and sprinkle with garlic powder and onion powder. Add chicken broth.
Cook the potatoes in a crockpot for 3 hours on High or 6 hours on Low.
Add butter and warm milk to the potatoes. Mash the potatoes with a potato masher until smooth. If more liquid is needed, add more milk until desired consistency.
Add salt and pepper to taste.
Sprinkle the mashed potatoes with chopped green onions or parsley.
