How Long Do Lamb Shanks Take to Smoke?
Plan on about 4 hours total for a classic smoke-then-braise lamb shank: roughly 2 hours of smoking to build flavor and bark, followed by about 2 hours of braising to break down the connective tissue and make the meat fall off the bone. That’s for the low-and-slow method most sources agree on — a Traeger-specific sear-first method (covered below) runs on a different timeline.
Lamb shank is a great cut to start with if you haven’t cooked lamb before. It’s smaller and cheaper than a whole leg or rack, and it’s much more forgiving than trying to slice a roast to a precise doneness — you’re braising it well past medium anyway, so a little extra time won’t ruin it.
What You’ll Need
- Lamb shanks — usually sold individually, 1-2 lb each.
- A binder — olive oil or yellow mustard, just enough to help the rub stick.
- A rub — a BBQ rub, simple SPG (salt, pepper, garlic), or a rosemary-forward herb rub all work well.
- Braising liquid — 1 cup beef or lamb broth, plus 1 cup red wine if you want it (Cabernet or Merlot work well; leave it out and use extra broth if you’d rather skip the wine).
- Aromatics — a sliced onion, a few cloves of garlic, and a couple of sprigs of fresh rosemary and thyme.
How to Smoke Lamb Shanks on a Traeger
Trim and Season the Shanks
Trim away any excess fat and silver skin so the meat is exposed to smoke. If you want a tidier presentation, you can french the bone by cutting and peeling back the meat at the thin end, but it’s purely cosmetic — skip it for a quicker, more rustic prep. Season generously with your rub of choice, pressing it into the meat on all sides.
Smoke Low and Slow at 225°F
Preheat your Traeger to 225°F using a pellet blend that pairs well with lamb — cherry, pecan, or oak are all good choices, and a cherry-hickory mix is a popular combination if you want something a bit bolder. Place the shanks directly on the grill grates and close the lid.
Smoke for about 2 hours, or until the internal temperature reaches 150-160°F. This stage builds the bark and gets real smoke flavor into the meat before it goes into the braise — once it’s covered in liquid, it won’t pick up any more smoke, so this is the part that matters most for flavor.
Build the Braising Liquid
While the shanks smoke, sauté the sliced onion and garlic in a little oil in a cast iron pot or dutch oven until softened, then add the broth, wine (if using), and herb sprigs. Bring it to a gentle boil, then drop it to a simmer.
Braise Until Fork-Tender
Once the shanks hit 150-160°F, transfer them into the pot with the braising liquid — they don’t need to be fully submerged, about halfway is fine. Cover the pot and either return it to the smoker or move it to your oven; once the lid is on, it won’t take on more smoke, so the choice is about convenience.
Braise at 300-325°F for another 2 hours or so, or until the internal temperature reaches 200-205°F. Roll the shanks over halfway through so each side spends time in the liquid. At this point the meat will have visibly shrunk and should be very soft — be careful moving it if you want to keep a bone-in presentation, since it will want to fall right off the bone.
Rest and Serve
Let the shanks rest for about 20 minutes before serving. If you want a sauce, strain the braising liquid, skim the fat, blend it with the cooked vegetables, then reduce it in a saucepan until it thickens. Season to taste and spoon it over the shanks.
The Traeger Sear-First Method (Alternative)
Traeger’s own house method takes a different approach if you’re short on time or want a deeper, roastier flavor instead of a long smoke:
- Preheat the Traeger to 450°F and season the shanks with your rub.
- Sear them directly on the grates until browned, about 20 minutes.
- Transfer to a dutch oven with beef broth, wine, and fresh herbs, cover tightly.
- Drop the temperature to 325°F and braise until the internal temperature reaches 180°F, about 3-4 hours.
This method skips the dedicated low-smoke stage in favor of a hot sear, so you get less pronounced smoke flavor but a shorter total prep before the braise starts. Either method gets you to fall-apart lamb — pick the low-and-slow version above if smoke flavor is the priority, or this one if you want to get the braise going faster.
Best Pellets for Smoked Lamb Shank
Cherry and hickory is a popular combination for lamb — cherry keeps things mellow while hickory adds some backbone. If you’d rather keep it simple, straight apple, pecan, or oak all work well too. Since the shanks only spend about 2 hours actually exposed to smoke, don’t overthink the pellet choice — almost any wood you enjoy will work.
If you don’t have a dedicated smoker or a Traeger, you can still get smoke flavor on a regular gas grill: set up for indirect heat, place a smoker box over the lit burner, and keep the shanks on the unlit side around 225°F.
What to Serve with Smoked Lamb Shanks
Smoked lamb shanks pair well with something to soak up the braising liquid — tomato orzo, roasted potatoes, polenta, or roasted vegetables are all good choices. If you’re serving a crowd, our smoked lamb shoulder roast is a good companion dish for a bigger BBQ spread, since it uses a similar herb-rub flavor profile but feeds more people.
FAQ
How long to smoke lamb at 225? For shanks specifically, about 2 hours at 225°F gets you to the 150-160°F internal temperature where you’d move to the braise. Larger cuts like a whole shoulder take considerably longer at the same temperature — see our smoked lamb shoulder roast guide for that timeline.
Do I need a Traeger specifically, or will any smoker work? Any smoker or grill capable of holding a steady low temperature will work for the low-and-slow method. A Traeger or other pellet grill just makes it easy to dial in and hold 225°F without much babysitting.
Can I skip the braise and just smoke the shanks all the way through? Not recommended. Shanks have a lot of connective tissue that needs a moist braise to fully break down — smoking alone tends to leave them chewy rather than fall-off-the-bone tender.
