Mashed potatoes have been a staple comfort food in the United States since the 19th century, originally popularized by European immigrants who brought boiled potato dishes. Over time they became a classic side for Thanksgiving, holiday meals, and everyday family dinners, symbolizing homey, hearty comfort.
