Tender, slow-braised lamb shanks are the kind of meal that makes the whole kitchen smell incredible. In this recipe, lamb is seared until beautifully golden, then slowly cooked with rosemary, thyme, garlic, vegetables, warm spices, and a rich chicken-stock braising liquid.
After several hours in the oven, the lamb becomes wonderfully tender and nearly falls from the bone. The flavorful cooking liquid is transformed into a silky herb-infused gravy with fresh mint, thyme, and a splash of red wine vinegar for balance. Served over creamy mashed sweet potatoes, this comforting dish makes an impressive centerpiece for a family dinner or special occasion.

How to Make Lamb Shanks with Herb-Infused Gravy
1. Prepare the Lamb
Preheat your oven to 400°F (200°C).
Use a sharp knife to make a few shallow cuts through the fatty side of each lamb shank. Season the meat generously with salt and freshly ground black pepper, making sure all sides are well coated.
2. Brown the Lamb
Heat the olive oil in a large heavy-bottomed skillet or Dutch oven over medium heat.
Add the lamb shanks and brown them thoroughly on every side, cooking for approximately 4–5 minutes per side. Take your time with this step—the deep golden color adds an important layer of flavor to the finished dish.
Once browned, transfer the lamb to a plate and set it aside.
3. Build the Braising Base
Place half of the rosemary and half of the garlic cloves in the bottom of a large cast-iron Dutch oven or another oven-safe pot.
Arrange the browned lamb shanks on top of the herbs. Scatter the remaining rosemary and garlic around the meat.
Add the chopped onion, celery, carrots, tomatoes, cinnamon sticks, thyme sprigs, smoked paprika, cumin, bay leaves, and crushed red pepper flakes if you want a little heat.
4. Add the Stock
Pour the chicken stock into the pot, adding enough to come slightly up the sides of the lamb shanks.
Place the pot over medium heat and bring the liquid to a gentle simmer. Avoid boiling it aggressively, as a slow, steady braise produces more tender meat.
5. Slow-Braise the Lamb
Cover the pot tightly with its lid and carefully transfer it to the preheated oven.
Cook for approximately 2½ to 3 hours, checking occasionally. If the liquid becomes too low, add a little more chicken stock or water.
The lamb is ready when it is exceptionally tender and the meat is beginning to pull away easily from the bones.
6. Rest the Lamb
Remove the pot from the oven and carefully transfer the lamb shanks to a plate.
Let them rest for 10–15 minutes while you prepare the gravy. Resting helps keep the meat juicy and gives you time to finish the sauce.
7. Prepare the Gravy
Skim any excess fat from the surface of the braising liquid. Remove the larger pieces of rosemary, thyme, cinnamon, bay leaves, and other herbs.
Leave approximately 2 cups of the flavorful braising liquid in the pot.
In a separate saucepan or suitable part of the cooking pot, melt the butter over medium heat. Whisk in the flour and cook briefly until it forms a smooth roux.
Gradually incorporate the flavorful braising liquid, scraping up any browned bits from the bottom of the pot. These caramelized pieces add even more depth to the gravy.
Allow the sauce to simmer gently until it reduces and thickens to your preferred consistency.
8. Add the Fresh Herbs
Finely chop the fresh mint and thyme and stir them into the finished gravy.
The fresh herbs add a bright contrast to the rich lamb and slow-cooked vegetables.
Just before serving, stir in the red wine vinegar. This small amount of acidity helps balance the richness of the sauce and brings all the flavors together.
Taste the gravy and adjust the seasoning with additional salt and black pepper if needed.
How to Serve
Spoon a generous portion of creamy mashed sweet potatoes onto each plate. Place a tender lamb shank on top and spoon plenty of the rosemary, thyme, and mint-infused gravy over the meat.
Finish with a sprinkle of freshly chopped herbs for a fresh, colorful touch.
For an especially cozy dinner, serve the lamb with roasted seasonal vegetables or a simple green salad.
Recipe Tips
Brown the lamb well.
Don’t rush the searing step. A deep golden-brown exterior creates flavorful browned bits that become part of the gravy.
Keep the braising liquid at a gentle simmer.
The lamb should cook slowly and evenly. A hard boil can make the meat less tender.
Check the liquid during cooking.
The lamb should remain surrounded by plenty of flavorful liquid. Add a splash of stock or water if the level becomes too low.
Give the lamb time.
Lamb shanks contain connective tissue that needs time to break down. If the meat isn’t tender after 2½ hours, continue cooking until it easily pulls away from the bone.
Don’t skip the vinegar.
A small amount of red wine vinegar gives the rich gravy a pleasant brightness and prevents the dish from tasting overly heavy.
Make the gravy your own.
For a thicker sauce, allow it to reduce a little longer. For a thinner gravy, add a splash of stock until you reach the desired consistency.
Frequently Asked Questions
Can I use four small lamb shanks instead of two large ones?
Yes. Four smaller shanks work very well. Keep an eye on them during cooking, as smaller pieces may become tender slightly sooner.
Can I prepare the lamb ahead of time?
Absolutely. Braised lamb shanks often taste even better after the flavors have had time to develop. You can prepare the lamb in advance, refrigerate it, then gently reheat it before serving.
What can I use instead of chicken stock?
Beef or vegetable stock can also be used. Beef stock will give the gravy a deeper, more robust flavor, while vegetable stock creates a lighter result.
How do I know when the lamb is done?
The lamb should be extremely tender. A fork should slide into the meat easily, and the meat should pull away from the bone with very little effort.
Can I serve this with something other than mashed sweet potatoes?
Certainly. Creamy mashed potatoes, polenta, cauliflower mash, couscous, or roasted vegetables would all pair beautifully with the lamb and gravy.
Storage
Allow leftovers to cool before transferring them to an airtight container. Refrigerate for up to 3–4 days.
For longer storage, the cooked lamb and gravy can be frozen in a freezer-safe container. Thaw overnight in the refrigerator and reheat gently until thoroughly hot.
