  • 1 (3 pound) bone-in leg of lamb, or more to taste

  • ½ cup red wine

  • 1 lemon, juiced

  • 2 tablespoons raw honey

  • 2 tablespoons Dijon mustard

  • 3 cloves garlic, minced

  • 1 tablespoon apple cider vinegar

  • 1 tablespoon dried rosemary

  • 1 teaspoon dried thyme

  • 1 teaspoon sea salt

  • ½ teaspoon fresh cracked pepper


  1. Bring leg of lamb to room temperature, about 2 hours.

  2. Pour wine into a slow cooker. Mix lemon juice, honey, mustard, garlic, vinegar, rosemary, thyme, sea salt, and pepper together in a bowl until a thick paste forms. Massage paste into the lamb using your hands; gently place into the slow cooker.

  3. Cook on Low, without removing the cover, for 5 hours. An instant-read thermometer inserted near the bone should read 145 degrees F (65 degrees C). Let lamb rest for 15 to 20 minutes.


Aluminum foil helps keep food moist, ensures it cooks evenly, keeps leftovers fresh, and makes clean-up easy.
