This is the type of dish where sous vide really stands out as a cooking method and gives you something that you can’t get with other cooking methods. A big advantage to cooking sous vide is how it locks juices and flavors into food.

The flavor for this leg of lamb comes from a fresh rosemary and thyme herb and spice mixture that has the time to penetrate deep into the lamb. This also is one of few recipes for leg of lamb where it helps to have a boneless leg of lamb.

Prep Time: 20 minutes
Cook Time: 12 hours
Total Time: 12 hours 20 minutes
Servings: 10 servings


  • 4 1/2 pound leg of lamb, boneless
  • 2 tbsp rosemary
  • 2 tbsp thyme
  • 2 tsp salt
  • 1 tsp pepper
  • 1 tsp smoked paprika
  • 4 cloves garlic
  • 1 1/2 tbsp olive oil
  • 1/2 lemon


  • Start by getting your sous vide cooking station set up and your immersion circulator set to 134℉.
  • Prepare the herb mixture by mincing the garlic, rosemary, and thyme and mixing them together with the salt, pepper, smoked paprika, and olive oil. Slice half a lemon into rounds.
  • Spread the herb mixture on the lamb, making sure to get into all the nooks and crannies. Put the lemon slices on the lamb and vacuum-seal everything in a plastic bag. You can use a heavy-duty freezer bag or a food saver that vacuums out the air.
  • Place the leg into the water bath and cook it for at least 10 hours to make sure it cooks all the way through.
  • After 10 to 14 hours take the lamb out of the water and the plastic bag. Place the lamb a medium high grill for five minutes, turn it over and grill the other side for another five minutes. Repeat this twice, making sure the grill doesn't flare up. The goal here is to get the outside of the lamb nice and crispy, without cooking the inside anymore.
  • Let the lamb rest under foil for 15 minutes. Slice the lamb to serve.


We recommend against cooking the leg of lamb more than 15 hours. At a certain point, so much of the fat leaches out that the tender meat can become a little mealy.
If you don't have a grill available you can also finish the lamb in a broiler. The purpose behind both methods is to finish the lamb using high heat for a short period to crisp up the outside, without cooking the interior anymore.
