作法
- 厚鍋以中大火加熱油。加入洋蔥翻炒一分鐘至剛變透明。加入牛肉撥散——煎至不再粉紅，約九十秒。
- 加入馬鈴薯與紅蘿蔔。再炒一分鐘讓食材裹上牛油——表面應發亮。這個步驟避免蔬菜後續散開。
- 倒入高湯煮至微滾。撇去前兩分鐘浮起的「あく」——這是日本廚師視為清淨風味必要的步驟。
- 加入清酒、味醂、糖——關鍵是先加一半醬油。蓋上落蓋（剪成大小直接壓在食材上的烘焙紙），中小火燉15分鐘。
- 加入剩餘醬油與蒟蒻絲。再燉8–10分鐘至馬鈴薯易刺穿但仍成形，湯汁減至約三分之一——底部略帶糖漿狀。
- 離火加蓋靜置10分鐘——風味在冷卻時滲入。盛盤，湯舀在食材周圍，撒上汆燙的甜豆莢。趁熱配飯吃；馬鈴薯燉肉隔夜更美味。

文化背景
馬鈴薯燉肉是日本家常料理中的傳奇——年輕男人傳統會要求追求對象做這道菜，是證明新伴侶能持家的料理。它的起源是海軍：據說東鄉平八郎元帥要廚師重現他在英國當見習軍官時吃的牛肉燉，廚師做出了這個高湯醬油版。落蓋（otoshibuta）是區別軟嫩、入味均勻的馬鈴薯燉肉與焦慮看鍋廚師的關鍵技術。
