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 cooking lamb in the slow cooker is the way to go. With my simple recipe you can enjoy lamb anytime of the year.

Key Ingredients

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.

How to Make Slow Cooker Leg of Lamb

  1. Rub the leg of lamb with a garlic, herb, and olive oil paste.
  2. Sear on all sides until nicely browned.
  3. Add vegetables and broth to the slow cooker, place the lamb on top, cover, and cook until fork-tender.

Tips & Variations

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

Make it a Complete Meal: Potatoes can be added to the pot for a full meal.

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

Less Greasy: Trim excess fat from the lamb to reduce grease, but leave a little for flavor. After cooking, you can easily degrease the sauce by blotting it with paper towels.
