Ingredients List

To make this flavorful Instant Pot Lamb Shoulder, you’ll need the following ingredients:

For the Lamb:

4 pounds (1.8 kg) bone-in lamb shoulder
2 tablespoons olive oil (or your preferred oil)
2 cups beef or chicken stock (preferably low-sodium)
4 anchovy fillets (optional but highly recommended for added umami)
2 tablespoons garlic purée (or 6 garlic cloves, minced)
2 teaspoons dried rosemary (or 2 tablespoons fresh, chopped)
1 teaspoon dried oregano
1 teaspoon sea salt (adjust to taste)
1/2 teaspoon black pepper
1 teaspoon paprika (for extra depth of flavor, optional)

1/2 teaspoon red pepper flakes (if you like a bit of heat)

Step-By-Step Cooking Instructions

Making this Instant Pot Lamb Shoulder is incredibly straightforward. You can follow the classic method that starts with a quick sauté, or you can opt for the dump-and-start version when you’re pressed for time. Here’s how to do both:

Prepare the Lamb

Remove the lamb shoulder from the fridge about 20–30 minutes before cooking to bring it to room temperature.
Pat the meat dry using paper towels. This helps it brown more evenly.
Season the lamb all over with salt, pepper, and paprika if using.

Sauté the Lamb (Optional)

Select the sauté function on your Instant Pot. Add the olive oil and let it heat up for about a minute.
Sear the lamb shoulder on both sides for 3–4 minutes per side until browned. This adds depth of flavor but can be skipped if you prefer the dump-and-start method.
Once browned, transfer the lamb to a plate.

Deglaze the Pot

Pour in about half a cup of your broth or stock and use a wooden spoon to scrape up any browned bits stuck to the bottom. This prevents a burn warning and adds flavor.

Build the Flavor Base

Add the remaining stock, garlic purée, and anchovy fillets into the pot. Stir to dissolve the anchovies.
Add the rosemary, oregano, and any other herbs or seasonings you’re using.

Return the Lamb

Place the lamb shoulder back into the Instant Pot. Spoon some of the liquid over the top.

Pressure Cook

Seal the lid and make sure the valve is set to sealing.
Cook on High Pressure for 90 minutes.
Once done, allow a Natural Pressure Release for 15 minutes, then switch to Quick Release to let out the remaining pressure.

Rest and Serve

Carefully remove the lamb from the pot and place it on a cutting board or serving platter.
Let it rest for about 10 minutes. This allows the juices to redistribute, keeping it moist and flavorful.
Slice or shred the lamb, depending on your preference. It should fall apart easily with a fork.

Optional Gravy

Use the leftover cooking liquid as a base for gravy. Select the sauté function again.
Add sliced onions and cook until soft.
Mix 1 tablespoon of cornstarch or arrowroot with 2 tablespoons of water to make a slurry, then stir it in to thicken the sauce.

How to Serve

The beauty of this lamb shoulder recipe lies in its versatility. Here are a few favorite serving ideas to inspire your next meal:

With Mashed Potatoes: Creamy mashed potatoes are a natural companion for rich, juicy lamb. Spoon some of the cooking juices or gravy over the top for the perfect pairing.
Couscous or Rice: A fluffy bed of couscous or basmati rice is ideal for soaking up the lamb’s savory juices. Add a handful of pomegranate seeds or chopped herbs for extra brightness.
With Roasted Vegetables: Serve alongside roasted carrots, zucchini, or Brussels sprouts for a well-rounded, colorful plate.
With Flatbread: For a casual, shareable spread, shred the lamb and serve with flatbreads, yogurt sauce, and a crisp salad.

Pairing Suggestions

Pairing your lamb shoulder with the right side dishes and drinks takes the experience to the next level. Here are some ideas to get you started:

Side Dishes:

Garlic Smashed Potatoes: Rustic and flavorful, they add the perfect crunch and softness combination.
Lemon Herb Couscous: Light and fluffy with a citrusy kick to balance the richness of the lamb.
Spinach Salad with Lemon Vinaigrette: A fresh, zesty salad cuts through the savory flavors and brightens the plate.
Grilled Asparagus or Green Beans: Simple but elegant, these veggies bring balance and texture.

Beverage Pairings:

Non-Alcoholic Sparkling Grape Juice: A festive option that pairs well with savory meat dishes.
Iced Mint Tea: Refreshing and light, it complements the herbs in the lamb perfectly.
Pomegranate Juice: Slightly tart and vibrant, it adds contrast to the rich lamb.

Storage, Freezing & Reheating Instructions

If you’ve got leftovers, you’re in luck. This lamb shoulder tastes even better the next day. Here’s how to store and enjoy it later:

Storage:

Place cooled lamb in an airtight container. Store in the refrigerator for up to 4–5 days.
Keep the cooking liquid separately if you plan to use it as a sauce or gravy.

Freezing:

Slice or shred the lamb and let it cool completely.
Store portions in freezer-safe bags or containers.
Freeze for up to 3 months. Label with the date so you don’t forget.

Reheating:

Thaw overnight in the fridge if frozen.
Reheat gently in a covered dish at 350°F (175°C) until heated through, about 20 minutes.
You can also reheat on the stovetop with a bit of stock or leftover sauce to keep it moist.

Common Mistakes to Avoid

Even though this recipe is simple, a few common errors can affect the final result. Here’s what to watch out for:

Skipping the Salt:
Underseasoning can make the lamb taste bland. Salt enhances all the other flavors—don’t forget it.

Overcrowding the Pot:
If you’re using a smaller Instant Pot, avoid squeezing in too large a cut of meat. It can affect cooking time and result in uneven texture.

Not Deglazing:
Skipping the deglazing step can cause a burn warning and affect the flavor. Always scrape up the browned bits after sautéing.

Overcooking After Pressure Cooking:
Once the lamb is done, remove it promptly after the pressure is released. Leaving it in the hot pot for too long can dry it out.

Forgetting the Natural Release:
This step is crucial. It helps the juices settle and keeps the meat tender. Don’t skip the 15-minute wait.

Pro Tips

Want to elevate your Instant Pot lamb shoulder to the next level? Try these tips:

Use Fresh Herbs When Possible:
Fresh rosemary and oregano add a brighter flavor than dried herbs, though either will work well.

Add Citrus Zest:
A bit of lemon zest stirred into the sauce or sprinkled over the lamb before serving gives it a fresh, unexpected twist.

Sear for Extra Flavor:
While the dump-and-start method is great, searing the meat first really enhances the depth and adds texture.

Use a Wire Rack (If You Have One):
Placing the lamb on a rack in the Instant Pot can help it cook more evenly, though it’s not essential.

Save the Broth:
Don’t toss the leftover cooking liquid. It makes an amazing base for soups, rice dishes, or even reheating leftovers.

Frequently Asked Questions (FAQs)

Can I make this recipe ahead of time?
Yes, and it’s even better the next day. Prepare it fully, then refrigerate. Reheat before serving.

Can I use boneless lamb shoulder?
Absolutely. It will cook a bit faster—try reducing the pressure time to 75 minutes.

Can I skip the anchovies?
You can, but they dissolve completely and add umami. You won’t taste fishiness—just depth of flavor.

What if I don’t have stock?
Water works in a pinch. Just add a bit more seasoning or a bouillon cube for flavor.

Can I use the slow cooker instead?
Yes. Sear the lamb first, then cook on low for 8–9 hours or on high for 5–6 hours.
