Ingredients:
- 4 large grass-fed lamb shanks (approx. 400g each)
- 2 tbsp extra virgin olive oil
- 1 tsp kosher salt
- 1 tsp cracked black pepper
- 1 large yellow onion, finely diced
- 2 large carrots, peeled and small-diced
- 2 stalks celery, finely diced
- 6 cloves garlic, smashed and peeled
- 2 tbsp tomato paste
- 1 cup dry red wine (Cabernet or Syrah)
- 2 cups beef bone broth
- 3 sprigs fresh rosemary
- 4 sprigs fresh thyme
- 2 dried bay leaves
- 2 tbsp unsalted butter, cold
- 1 tbsp cornstarch
Instructions:
- Pat the lamb shanks completely dry with paper towels to ensure a proper sear. Season aggressively on all sides with kosher salt and cracked black pepper.
- Heat the extra virgin olive oil in a heavy-bottomed skillet or Dutch oven over medium-high heat until it shimmers.
- Brown the shanks in batches, searing until they develop a deep, mahogany-colored crust on all sides. Remove shanks and transfer to the slow cooker.
- In the same skillet, sauté the diced onion, carrots, and celery until softened. Add the smashed garlic and tomato paste, cooking for 2 minutes until the paste darkens.
- Deglaze the pan with the red wine, scraping up the browned bits (fond) from the bottom. Pour the mixture over the shanks in the slow cooker.
- Add the beef bone broth, rosemary, thyme, and bay leaves. Cover and cook on Low for 8 hours (or High for 6 hours) until meat is fall-off-the-bone tender.
- Carefully remove the shanks and keep warm. Strain the braising liquid through a fine-mesh strainer into a saucepan, discarding the solids.
- Simmer the liquid and whisk in the cornstarch slurry. Once thickened, whisk in the cold unsalted butter to create a glossy, velvet-textured gravy. Serve over the shanks.
