Kuanfen noodles (Chinese: 宽ç²Â) are flat Chinese noodles made from potatoes. They are commonly used in mala hotpot () and stew (Suan la fen). They can also be made from purple potatoes.
Kuanfen, at least four to five centimeters wide, reflects the "big" () aesthetic of the northwestern China: spacious landscapes, hearty food, tradition of smashing the wine bowl ().
