Lamb – What’s The Best Cut?

This largely depends on how many people you’re hoping to feed or if you want leftovers. There are three cuts you can choose from when you’re looking to purchase a leg of lamb. Each of these cuts will yield a different result when cooked and will also give you less or more depending on which you choose:

  • The Whole Leg: A whole leg of lamb will be between 5 to 6 pounds, which will easily feed eight people or six people with leftovers. What you see here is a 5-pound whole leg of lamb.  If you’re looking to purchase a whole leg but you’re feeding less than that, you can have the leg divided up by the butcher or cook it whole and use the meat for other recipes during the week.
  • A Butterflied Leg: This cut is the whole leg just cut so the meat is butterflied for ease of cooking. This brings the meat away from the bone so you don’t have to worry too much about undercooking. This will feed roughly the same number of people, but makes it easier for the home cook to portion the meat for serving and saving.
  • Lamb Shanks: Shanks are cut off of the smaller end of the leg and are best for individual portions. So if you’re having a dinner party and you really want to make an impression, plating up individual shanks with roasted vegetables or mashed potatoes will make for a beautiful presentation.

Is Lamb Healthy?

Yes actually. Lamb has become more popular recently due to it being an ideal protein source for those who are on low-carb diets or doing paleo or whole30. This recipe in particular is great for those who want all of the flavors without any guilt. It can be used in a variety of dishes like lamb gyros, kebabs, or served simply grilled alongside seasonal vegetables.

Boneless Or Bone-In?

You can use bone-in or boneless leg of lamb in this recipe. It all depends on what kind of dish you want to make and how large your appliance is. For the slow cooker or Instant Pot, using a bone-in leg of lamb can help keep your meat tender and juicy but that doesn’t mean that going boneless will leave your meat dry. My 5-pound bone-in leg of lamb did not fit in my 6-quart slow cooker, I had to use my 8-quart. If it had used boneless leg of lamb, I could have cut easily the lamb into pieces to up to make it fit. That’s one benefit of using a boneless cut. If you’re using a larger bone-in cut of meat, make sure you have an appliance that will fit it. Or just boneless. I do you use boneless, I recommendation wrapping the meat in twine first to keep it together during the cooking process.

What To Serve This With?

This slow cooker leg of lamb is great with roasted vegetables and mashed potatoes or mashed cauliflower. Having said that, you could always get creative with it as well.

If you want something a little richer you could always prepare some homemade mac and cheese along with some vegetables.
