These mashed potatoes are fast and simple to prepare and cook. The potatoes are quickly cooked in the microwave then mashed with milk, butter, and seasonings. 

Use peeled baking potatoes, russets, or Yukon gold, or use scrubbed unpeeled red potatoes. This is a great way to have homemade mashed potatoes when you're short on time or have limited cooking options. 

Another fast option for potatoes is this recipe for mashed potatoes using the Instant Pot or electric pressure cooker.
