How to Make Instant Pot Lamb Shanks Recipe

Step 1: Prepare and Season the Lamb Shanks

Start by trimming any excess fat off the lamb shanks and pat them dry with paper towels; this helps achieve a beautiful sear. Then season generously with salt and freshly ground black pepper so every bite delivers flavor straight to the meat.

Step 2: Sear the Lamb Shanks

Heat the oil in a skillet over medium-high heat. Carefully sear each side of the lamb shanks for about 7 minutes until golden brown. This step is key for locking in flavor, creating a rich crust, and giving your Instant Pot Lamb Shanks Recipe that irresistible aroma that fills your kitchen.

Step 3: Add Ingredients to the Instant Pot

Transfer the seared lamb shanks into the Instant Pot. Add chopped onion, celery, garlic, bell pepper, baby carrots, flour, parsley, Worcestershire sauce, tomato paste, broth, red wine, thyme sprigs, salt, and pepper. Give everything a good stir to combine all the delicious components.

Step 4: Cook Under Pressure

Secure the Instant Pot lid and set the vent to sealing. Select the Pressure Cook setting. Note that it takes around 10 minutes for the pressure to build up before cooking begins. Let the lamb shanks cook under pressure for 45 minutes to 1 hour. When the timer finishes, allow natural pressure release—resist the urge to quick-release, as this ensures the meat stays tender and juicy.

Step 5: Finish and Serve

Once the pressure has fully released, carefully open the lid and admire the rich sauce and tender lamb. The meat should be fall-apart soft, infused with layers of flavor from the vegetables, herbs, and wine. Serve immediately for the best experience.

A sprinkle of fresh parsley or chopped thyme elevates the dish visually and adds a burst of fresh herbal brightness that cuts through the richness of the lamb and sauce beautifully.

Creative Ways to Present

For a dinner party, plate a single lamb shank atop a swirl of bright herb mashed potatoes, drizzle with extra sauce, and garnish with a fresh sprig of thyme. For a rustic family meal, serve in a large bowl with chunky bread on the side to mop up every last drop.

Make Ahead and Storage

Storing Leftovers

Allow the lamb shanks and sauce to cool completely before transferring to airtight containers. Properly stored, they will keep well in the fridge for up to 3 days, making them perfect for easy weekday reheats.

Freezing

This recipe freezes beautifully. Divide into portions, place in freezer-safe containers or bags, and freeze for up to 3 months. Thaw overnight in the fridge before reheating for a convenient gourmet meal anytime.

Reheating

Gently reheat lamb shanks in a covered pan over low heat or in the microwave. To prevent drying out, add a splash of broth or water and cover to keep moisture locked in while warming through.

FAQs

Can I use bone-in or boneless lamb shanks for this recipe?

Bone-in lamb shanks are ideal because the bone adds incredible flavor and richness to the sauce during cooking, but if you can only find boneless, it will still work; just adjust cooking time slightly as boneless tends to cook faster.

What if I don’t have red wine on hand?

You can substitute with additional broth or a splash of balsamic vinegar for acidity. The wine adds depth but the recipe remains delicious even without it.

How do I thicken the sauce if it’s too runny after cooking?

Remove the lamb shanks and switch the Instant Pot to sauté mode. Stir in a tablespoon of flour or cornstarch mixed with water to create a slurry, then simmer until the sauce thickens to your liking.

Can I make Instant Pot Lamb Shanks Recipe without an Instant Pot?

Absolutely! You can sear the lamb shanks on the stove, then transfer everything to a slow cooker and cook on low for 6-8 hours or bake covered in a Dutch oven at 325°F for about 2.5-3 hours until tender.

Is it possible to double the recipe for larger groups?

Yes, just make sure your Instant Pot is large enough to hold the increased volume without exceeding the max fill line. You may need to increase cooking time slightly for larger portions.
