👉 What does lamb shoulder taste like? The texture of this lean meat is similar to beef, but the flavor is rich and earthy.

I’ve personally come to love lamb over the years, and I think it’s a wonderful protein for hearty recipes like my Irish Lamb Stew, and rustic Italian Lamb Meatballs. I buy my lamb from Porter Road because the taste and quality is 💯.

Ingredients and Substitutions

This recipe contains just eight simple ingredients, total. Because when you start with great ingredients, you don’t need to do much to make them shine! Here are the ingredients you’ll need:

For this recipe, use a whole bone-in lamb shoulder OR lamb shoulder chops, whichever you prefer!

👉 What kind of cut is lamb shoulder? Lamb shoulder is a tough, fatty cut of meat taken from the top of the animal’s back. Lamb shoulder is best cooked slowly to allow the meat to tenderize and the fat to render, until it’s fall apart tender. It’s also budget friendly compared to other cuts of lamb (about 1/3 the price of a leg of lamb the same size).

  • Broth: You can use either broth or stock. I typically use chicken broth or vegetable broth, but beef bone broth would be great too.
  • Vinegar: An acidic ingredient like vinegar helps to marinate and tenderize the meat. I prefer red wine vinegar, but balsamic vinegar would add a fantastic Italian flavor.
  • Italian Seasoning: Making your own seasoning blend ensures that it’s sugar-free has no preservatives. If it’s more convenient to use store-bought, feel free!
  • Aromatics: Use either a white or yellow onion, and a couple of fresh garlic cloves or a jar of minced garlic.
  • Fresh rosemary sprigs: This is for garnish, so you can omit it without affecting the flavor of the dish.
  • Arrowroot powder, for the gravy. If you’re not following Whole30 or Keto, feel free to substitute any other thickener, like cornstarch or all-purpose flour.

How to Make a Perfect Lamb Shoulder

Scroll down to the recipe card for the full step by step instructions! ⬇️

Prep the vegetables: Quarter the onions and remove the garlic from their skins. Guess what? You’re DONE with the knife & cutting board. Go ahead and put them away because you don’t need them anymore!

Layer the veggies in the bottom of the crockpot. You don’t have to get fancy with it, just scatter them.

Set the lamb shoulder on the vegetables. Be sure the fat cap is facing up (this will prevent the vegetables from being saturated with fat). The roast should be partially submerged in the liquid, but not completely covered.

Sprinkle the meat with Italian seasoning. If your seasoning blend is salt-free, feel free to season the lamb shoulder with one-half teaspoon of salt as well.

Cover the slow cooker with a lid and turn it on. Now prepare yourself, because as it cooks, the most delicious smell will begin to fill your house. It’s so delicious that waiting is almost torturous!

Whole Bone-in Lamb Shoulder Cook Times

  • High: 4.5 to 5.5 hours
  • Low: 7 to 8 hours

Note: For lamb shoulder chops, cook on Low for 5.5 to 6.5 hours, or on High for 3 to 4 hours.

When the lamb shoulder is ready, you should be able to shred the meat easily with a fork (no knife necessary!).

Remove it from the pot and set it on a serving platter or cutting board. Then, tent it loosely with foil and let it rest for about 10 minutes. *This allows the juices time to absorb back into the meat.

Prepare the Gravy

Strain the cooking liquid. Pour or ladle the liquid in the crockpot through a fine mesh sieve. Let it strain into a 2-quart (or larger) saucepan over medium-high heat. *You can discard the onion and garlic that are in the strainer.

Whisk in the thickener. Whisk the arrowroot powder or whatever thickener you're using into the liquid and let the gravy simmer, whisking often, until it thickens a bit. Taste the gravy, then season it with salt and pepper.

Remove the lamb shoulder bone and shred the meat. Last, go back to the rested lamb. Use two forks to pull apart the pieces of the cooked lamb. *Discard the bones and any large pieces of fat.

Sprinkle lightly with salt and pepper and serve with a healthy drizzle of the gravy and garnish with rosemary.

Instant Pot Adaptation

Just about any slow cooker recipe can be adapted for cooking in the Instant Pot, and this recipe is no exception! Here's how to make a bone in lamb shoulder in your trusty Instant Pot.

Optional step: Set the Instant Pot to sauté mode and add about 2 tablespoons of olive oil. Pat the lamb shoulder dry and season with salt and pepper. Once the oil is heated and shimmering, brown the roast on all sides, about 3-4 minutes per side.

Next, add the onions, garlic, vinegar, and broth to the Instant Pot. Secure the lid and turn to High Pressure. Set for 45 minutes, then once it's done cooking, allow for a natural pressure release (allow the steam to naturally dissipate). This usually takes about 15 minutes.

Serving Suggestions

Roasted root vegetables, especially red potatoes and carrots, taste great with the slow cooked lamb. To make them, quarter the veggies, then toss with oil, salt, and pepper, and bake at 425°F for 35 minutes, turning once.

To keep it Keto and Low Carb, serve your lamb with cauliflower mashed potatoes. You may want to serve it with a healthy spinach salad, or cook up some green beans in the air fryer, or roast a spaghetti squash.

If your diet allows, pair it with a lovely bed of dill rice.

A fancy beverage like lavender lemonade will complete this lovely holiday meal perfectly. Or enjoy a sweet dessert like this adorable Easter cookie cake.

Instructions

  • Quarter the onions and remove the garlic from their skins. Add the onions, garlic, broth, and vinegar to the bottom of the slow cooker.
  • Set the whole lamb shoulder in the slow cooker, with the fat cap facing up. Sprinkle the top of the lamb shoulder with the Italian seasoning. If the Italian seasoning blend does NOT contain salt, sprinkle the roast with about 1/2 teaspoon of salt as well.
    Cover and turn the slow cooker on. Cook on Low heat for 7-8 hours, if time allows. Otherwise, set it to cook on High heat for 4.5-5.5 hours.
    Note: If using chops instead of a whole lamb shoulder, cook on high for 3-4 hours or low for 5.5 to 6.5 hours.
  • Test the tenderness of the lamb close to the end of cook time. If it's so tender that you can easily pull the meat apart with a fork, it's ready.
    Carefully remove the lamb from the slow cooker and set it aside on a large rimmed plate. Spoon a little liquid from the slow cooker over the meat. Cover it loosely with a piece of tin foil and let it rest.
  • Meanwhile, prepare the gravy. Strain all the liquid from the slow cooker into a medium sauce pan to remove the large pieces of onion and garlic. Turn to medium heat and bring to a simmer.
    Whisk the arrowroot powder into the simmering gravy, continuing to whisk occasionally as it thickens, for about 10 minutes. Season with salt and pepper. Note: If your arrowroot powder becomes clumpy, use an immersion blender to blend the clumps out.
  • Last, go back to the rested lamb. Use two forks to pull apart the pieces of the cooked lamb. Set aside the bones and any large pieces of fat.
    Serve the lamb with a healthy drizzle of the gravy, a little salt and pepper, and garnish with rosemary.

Notes

Instant Pot Adaptation
Optional step: Set the Instant Pot to Saute mode and add about 2 Tablespoons of olive oil. Pat the lamb shoulder dry and season with salt and pepper. Once the oil is heated and shimmering, brown the roast on all sides, about 3-4 minutes per side.
Next, add the onions, garlic, vinegar, and broth to the Instant Pot. Set the lamb in the Instant Pot and sprinkle with the Italian seasonings. Secure the lid and turn to High Pressure. Set for 50 minutes, then once it's done cooking, allow for a natural pressure release (allow the steam to naturally dissipate).
