薄荷酱（英语：mint sauce）是一种酱料，传统做法是将切碎的留兰香浸于醋中，并加上小量糖。有时也会加上鲜榨的青柠汁。酱的浓稠度应与高脂奶油相若。薄荷酱在英国和爱尔兰菜是烤羊肉的传统配搭（但一般不会用于其他肉类），在某些地区也会用于搭配豌豆糊。

食谱中使用新鲜薄荷叶的地方可以用薄荷酱来取代。可以把薄荷酱涂于面包或吐司上食用，也可以加上酸奶制成印度薄荷酱。像薄荷酱般的“酸甜”酱在中世纪欧洲相当普遍（当时的法国菜和意大利菜比英国菜更常使用薄荷）；然而，它们在中世纪以后便开始逐渐消失，到进入现代]时几乎在欧洲绝迹。

Mint sauce is a sauce traditionally made from finely chopped spearmint leaves, soaked in vinegar, and a small amount of sugar. Occasionally, the juice from a squeezed lime is added. The sauce should have the consistency of double cream. In British and Irish cuisine it is traditionally used as a complement to roast lamb (but usually not other roast meats) or, in some areas, mushy peas.
