I don’t hear too many people cooking with lamb, and rightfully so. It can seem a little intimidating to cook with a meat that’s not as traditional as beef, chicken, or pork. But I can assure you that it packs a powerful flavor.

Slow cooking helps to take the guesswork out of how long to cook lamb, let alone at the “perfect” temperature. The seasonal rub you’ll create with minced garlic, rosemary, thyme, paprika, salt, and pepper will infuse the lamb with a tasty flavor combination. The celery and carrots not only help with flavor but also add overall heartiness to the meal. A perfect meal for Easter or Christmas.

Recipe Ingredients

ingredients for slow cooker lamb on a table.
  • Leg of Lamb: You can use a boneless leg of lamb or a bone in leg of lamb. I recommend grabbing one that’s at least 4-5 pounds.
  • Broth: I used chicken broth but you can also use beef broth.
  • Vegetables: A couple of shallots (or onion), about four carrots (peeled and chopped), and two stalks of celery (chopped).
  • Olive Oil: Used to help make a paste for the seasoning mixture.
  • Seasonings: Garlic cloves (minced), fresh rosemary and fresh thyme leaves (both chopped), paprika, kosher salt, and black pepper.

Variations

You can substitute ½ cup of the broth with some red wine for a deeper flavor.

Potatoes can be added to the pot for a full meal.

Make the recipe your own by adding Worcestershire sauce, balsamic vinegar, or red pepper flakes.

Step Four – To the slow cooker, add the shallots, carrots, and celery.

Step Five – Place the lamb over the vegetables.

Step Six – Pour the chicken or beef broth, the liquid should reach about halfway up the lamb.

Step Seven – Cover the crockpot and cook the lamb leg on LOW heat for 6-8 hours, or until the meat is tender and easily pulls apart with a fork. Once cooked, remove it from the slow cooker and allow it to rest for a few minutes before slicing. Enjoy! Serve the slow cooker roast lamb with the juices from the slow cooker.

Recipe FAQs

How do I reduce the amount of grease in the slow cooker?

Trim excess fat from the lamb to help reduce the amount of grease in the slow cooker. Remember to leave some of the fat for added flavor. You can degrease the sauce (after cooking) by placing paper towels over the sauce and then discarding it.

Can I make a gravy with the juices?

Yes! Serve the lamb with a side of mint sauce or gravy made from the cooking juices. 

How do I store leftover lamb?

Leftovers can be stored in the refrigerator for up to 3 days in an airtight container. For longer storage, place sliced lamb in freezer-safe bags or containers for up to 2 months. Thaw frozen lamb in the refrigerator overnight.
