Speedy Slow Cooked Lamb may sound contradictory but when you’ve forgotten to defrost your meat the night before, and 2pm rolls around, you no longer have 6-8 hours of slow cooking time.  Not to worry, you can still achieve tender, juicy lamb and have dinner ready by the time you come home.

I’ve recently started to buy boneless lamb leg from Costco.  One $30 leg makes about 8 meals, a really good deal!  I split the leg in two and froze the other half for a later date.  The first time I made lamb in the slow cooker I had it on low for 3 hours and 1 hour on high and the leg came out a flavourful and juicy.  For the second half of the leg, I reversed the process and cooked the lamb for 4 hours on high and 1 hour on low and the result was very different.  The leg fell apart into tender strands and chunks, and my mouth watered as I pulled the meat apart.  I added different root vegetables each time, they give another layer of flavour and are nice and soft after being cooked in lamb juice.  Squash, potatoes, parsnips –  you can’t go wrong!

The pulled lamb was so versatile!  We used the meat for tacos on Taco Tuesday and in a carb-free root vegetable bowl.  I plan to blend the remaining vegetables with my canned tomatoes and add the leftover meat to make a lamb ragu sauce – stay tuned for those photos!

Speedy Slow Cooked Lamb


  • Boneless leg of lamb (depending on the size of your slow cooker) approx 3 pounds
  • Zest from half a lemon
  • 1 tablespoon olive oil plus more for drizzling
  • sea salt and freshly ground pepper
  • 1 tablespoon fresh rosemary
  • 2 tablespoon fresh mint
  • 4 garlic cloves, trimmed and peeled
  • ¾ cup dry red wine
  • ½ cup low sodium beef broth
  • 2 pounds root vegetables scrubbed and chopped into 1 inch cubes
  • (I've used various combinations of sweet potato, yellow potato, parsnips and butternut squash)


  1. Heat a large cast iron pan on medium high heat.
  2. Rub lamb with olive oil and a sprinkling of sea salt. Sear each side for 30 seconds. Remove lamb and place on plastic cutting board. Deglaze the pan with ¼ cup of red wine.
  3. In a food processor, combine lemon peel, garlic, olive oil, ½ teaspoon sea salt, ½ teaspoon ground pepper, mint and rosemary. Process and spread paste over lamb, making sure to get into all the little crevices.
  4. Place lamb in slow cooker along with sauce from the deglazed pan, root vegetables, broth and ½ cup of red wine.
  5. Cook on high for 4 hours, then for 1 hour on low.
  6. Remove lamb from slow cooker and pull apart using a carving fork. Using a slotted spoon, remove root vegetables.
  7. Reserve juice for gravies or for cooking quinoa.
  8. Serve lamb alongside root vegetables or in a taco.
  9. Root vegetables can be blended into a tomato sauce and lamb can be added to make a ragu.


I leave the skin on the root vegetables to add flavour to the lamb, with the exception of the butternut squash which has to be peeled.
