作法
- 牛肉以魚露、五香粉與一大匙咖哩粉醃至少1小時，最好4小時。
- 做胭脂籽油：4大匙油與胭脂籽小火加熱5分鐘。過濾丟掉籽。油應呈深橘紅。
- 厚鍋以中大火加熱胭脂籽油。牛肉分批煎4分鐘至各面褐色。撈出。
- 同鍋加剩餘2大匙中性油，洋蔥煮6分鐘至軟。加大蒜、薑、香茅、八角、月桂葉與剩餘咖哩粉炒2分鐘至香氣四溢。
- 加番茄醬攪90秒——應略變深。把牛肉與肉汁回鍋。倒入高湯與椰子水；肉應剛淹過。加糖。
- 煮至微滾，加蓋以最小火煮90分鐘。加紅蘿蔔再煮30分鐘至肉與紅蘿蔔軟嫩、湯收成光亮油紅醬。撒香料。配酥脆麵包（越式長棍）沾或粗米線上桌。

文化背景
Bo kho是越南對法式燉牛肉的回應——牛肉燉湯透過殖民廚房傳入越南，一個世紀以胭脂籽、香茅、魚露與八角越南化。西貢早餐攤舀入碗中配酥脆越式長棍蘸著吃；也作為午餐麵碗澆在粗米線上（bo kho banh mi或bo kho hu tieu）。湯的紅色顯示胭脂籽用得慷慨；褐色bo kho是廚師省略此步的徵兆。
