Roast lamb with mint sauce potatoes

Bec Lloyd
Using your slow cooker for this lamb is like having your Nana come visit and bake a feast for you during the day. The mint sauce is a revelation - zingy and perfectly balanced for the rich lamb. Part of our September 2020 Meal Plan, so make sure you subscribe to receive yours next month.

Servings 6


  • 1 kg potatoes washed and peeled chopped into quarters
  • 4 carrots peeled and chopped into big pieces to match the potato pieces
  • 2 cloves garlic finely chopped
  • 1 teaspoon salt
  • 1 tablespoon olive oil
  • 1 kg leg of lamb
  • 2 stalks fresh rosemary
  • 1 cup fresh mint leaves very finely chopped
  • 1 tablespoon apple cider vinegar
  • 1 tablespoon raw sugar


Slow cooker

  • Rub a very small amount of olive oil on the base of the slow cooker
  • Add the potatoes and carrots
  • Score the top of the lamb and rub with the garlic and salt
  • Place the leg of lamb over the top of the potatoes
  • Top with the rosemary 
  • Cook on low for 8-10 hours

Mint sauce

  • The mint should be as finely chopped as possible, use a food processor if needed
  • Add the mint to a bowl and slowly add the vinegar a few drops at a time, stirring 
  • You do not want your mint sauce too runny
  • Then add the sugar (to taste) and whisk together well
  • Pour into a sealable glass jar and place in the fridge until needed

To serve

  • Check the lamb and make sure it is cooked all the way through and potatoes can be pierced easily with a fork
  • Slice the meat off the bone 
  • Prepare servings of vegetables with slices of the lamb and top with a dollop of the mint sauce
  • Store leftover lamb in the fridge in a sealed container


You ideally want leftover roast lamb so depending on your family size you may need to adjust your batch sizing. See this related recipe for Leftover Greek Lamb Wraps.
For extra colour and flavour you may sear the lamb in a fry pan before slow cooking.
