Ingredients

Here’s what you’ll need to create this tender and flavorful Lamb Shank with Creamy Mashed Potatoes:

For the Lamb Shank:

  • lamb shanks (about 1-1.5 lbs each)
  • 1 tbsp of olive oil
  • onion, finely diced
  • garlic cloves, minced
  • 2 cups of beef broth (low-sodium recommended)
  • Salt and pepper, to taste
  • Fresh rosemary, for garnishing (optional)

For the Creamy Mashed Potatoes:

  • 4 large potatoes, peeled and chopped (russet or Yukon Gold recommended)
  • 2 tbsp of butter (for potatoes)
  • 1/2 cup of heavy cream
  • Salt and pepper, to taste

Swaps and Notes

  • Lamb Shanks: Choose good quality lamb shanks. They are ideal for slow simmering, resulting in tender, flavorful meat. Lamb shoulder (cut into large chunks) can be a substitute, but adjust cooking time.
  • Onion & Garlic: Finely diced onion and minced garlic provide an aromatic base for the lamb.
  • Beef Broth: Low-sodium beef broth is recommended to control the saltiness. Lamb broth or a mix of beef broth and red wine can add even more depth.
  • Olive Oil: For searing the lamb.
  • Potatoes (Mashed): Russet potatoes are excellent for fluffy mashed potatoes. Yukon Gold potatoes offer a creamier texture.
  • Butter (Mashed Potatoes): Unsalted butter is preferred to control saltiness.
  • Heavy Cream: Essential for rich, creamy mashed potatoes. Milk or half-and-half can be used for a lighter version, but adjust consistency.
  • Salt & Pepper: Season to taste for both lamb and potatoes.
  • Fresh Rosemary: Adds a beautiful aromatic garnish. Fresh thyme can also be added during the lamb simmer for deeper flavor.

Instructions

Let’s cook this magnificent Lamb Shank with Creamy Mashed Potatoes!

For the Lamb Shank:

  1. Sear the Lamb: Begin by heating 1 tablespoon of olive oil in a deep pot or Dutch oven (a heavy-bottomed one is ideal for slow simmering) over a medium-high flame. Add the lamb shanks to the hot pot, searing each side for about 4-5 minutes until they achieve a beautiful golden-brown crust. This searing step is crucial for developing deep flavor. Remove the seared lamb shanks from the pot and set them aside on a plate.
  2. Sauté Aromatics: In the same pot with the residual pan drippings, add the finely diced 1 onion and minced 3 garlic cloves. Sauté over medium heat, stirring occasionally, until the onions are clear and fragrant, about 4-5 minutes. Scrape up any browned bits from the bottom of the pot.
  3. Simmer the Lamb: Pour the 2 cups of beef broth into the pot, stirring well to combine with the sautéed aromatics and deglaze the pan. Bring the broth to a gentle simmer. Carefully reintroduce the seared lamb shanks to the pot. They should be mostly submerged in the liquid. Cover the pot tightly with a lid and let it simmer on low heat for about 2 hours, or until the meat is incredibly tender and easily falls off the bone. The long, slow simmer is key to perfect lamb shanks.
    • Check for Tenderness: After 2 hours, check the lamb for tenderness. If not falling off the bone, continue simmering, checking every 15-20 minutes.

For the Creamy Mashed Potatoes:

  1. Boil the Potatoes: While the lamb is simmering, prepare your mashed potatoes. In a large pot, bring plenty of salted water to a rolling boil. Add the 4 large peeled and chopped potatoes. Cook until they are very tender when pierced with a fork, roughly 15-20 minutes. Drain the potatoes thoroughly and return them to the empty pot.
  2. Mash the Potatoes: Incorporate the 2 tablespoons of butter and 1/2 cup of heavy cream into the drained potatoes. Using a potato masher, a fork, or an electric mixer, mash until they are smooth and creamy, with no lumps remaining. Season generously with salt and black pepper to taste.

Serve:

  1. Adjust Lamb Seasoning: Once the lamb is tender, adjust seasoning with salt and pepper to taste in the braising liquid.
  2. Plate the Dish: Dish out a hearty bed of creamy mashed potatoes onto serving plates. Carefully place one tender lamb shank atop the mashed potatoes.
  3. Garnish: Spoon some of the delicious pan juices/sauce from the lamb over the lamb shank and mashed potatoes. Garnish generously with fresh rosemary sprigs or chopped fresh rosemary for a beautiful presentation and aromatic finish. Serve immediately!

Tips for Success

  • Sear Lamb Thoroughly: Don’t skip searing the lamb shanks. This creates a flavorful crust and adds depth to the braising liquid.
  • Low and Slow Simmer: The long, gentle simmer is crucial for tender, fall-off-the-bone lamb. Resist the urge to increase the heat.
  • Drain Potatoes Well: Ensure potatoes are thoroughly drained before mashing for the creamiest, non-watery mash.
  • Warm Cream/Butter for Potatoes: Using warm butter and heavy cream for mashed potatoes helps them incorporate smoothly and keeps the potatoes hot.
  • Season in Layers: Season the lamb, then the aromatics, and finally adjust the gravy/sauce at the end. Taste and adjust both lamb and mashed potatoes before serving.
  • Rest Lamb: While cooked in liquid, allowing the lamb to rest briefly on the plate before serving allows juices to settle.

Storage and Leftover Tips

Lamb Shank with Creamy Mashed Potatoes makes fantastic leftovers!

  • Refrigeration (Lamb): Store cooled leftover lamb shanks and their sauce in an airtight container in the refrigerator for up to 3-4 days. The sauce will thicken.
  • Refrigeration (Mashed Potatoes): Store cooled mashed potatoes separately in an airtight container for up to 3 days.
  • Reheating: Reheat lamb and sauce gently on the stovetop over low heat, adding a splash of broth if needed. Reheat mashed potatoes gently with a splash of milk/cream on the stovetop or in the microwave.
  • Freezing: Cooked lamb shanks (removed from bone and stored in sauce) freeze well for up to 2-3 months. Mashed potatoes can be frozen, but their texture might change slightly (become more mealy) upon thawing. Thaw in the refrigerator overnight before reheating.
