Ingredients
  

  • 1 leg of lamb (3–4 lbs, bone-in)
  • 2 tbsp fresh rosemary (chopped (or 2 tsp dried))
  • 3 cloves garlic (sliced or chopped)
  • ¼ cup fresh mint leaves (chopped)
  • ½ cup vinegar (white or apple cider)
  • 2 tbsp sugar

Instructions
 

Step 1: Prepare the Lamb

  • Rinse and pat dry the lamb leg.
  • Make small incisions in the meat and insert sliced garlic and rosemary.

Step 2: Mix the Baste

  • In a small bowl, combine chopped mint leaves, vinegar, and sugar. Stir until sugar dissolves.

Step 3: Roast

  • Place lamb in a roasting pan. Roast uncovered at 350°F (175°C) for about 30 minutes per pound.

Step 4: Baste

  • Every 20–30 minutes, baste the lamb with the mint vinegar mixture.

Step 5: Rest and Serve

  • Let the lamb rest for 10 minutes before slicing. Serve with pan juices or additional baste.

Tips

  • Let the lamb rest 10 to 15 minutes before slicing to retain juices
  • Finely chop mint leaves for a smoother sauce
  • Adjust sugar in the mint sauce for a sharper or sweeter finish
  • Add extra garlic chips for a stronger savory flavor
  • Baste the lamb every 20 to 30 minutes while roasting
  • Use fresh rosemary rather than dried for best aroma
  • Serve with roasted potatoes or root vegetables
  • Mint sauce can be made ahead and refrigerated
  • Works well with bone-in or boneless leg of lamb
