Ingredients You'll Need

Success starts at the butcher counter. Look for shanks that are thick through the meaty end—about 1½ lb (680 g) each—so they stay juicy after the long cook. A thin membrane on the exterior is fine; it will melt, but trim excess fat so the sauce doesn’t become greasy. My local market carries both fore and hind shanks; either works, though hind are meatier and look dramatic on a platter. Ask your butcher to “French” the bone if you want that elegant exposed look, or save a few dollars and do it yourself with a sharp paring knife.

The braising liquid is where layers of flavor build. I combine equal parts dry red wine and low-sodium chicken stock; wine adds acidity and fruit, while stock keeps the sauce savory. Choose a wine you’d happily drink—my go-to is a Côtes du Rhône because it’s inexpensive yet full-bodied. Crushed tomatoes add sweetness and body, tomato paste concentrates umami, and a single anchovy fillet melts into oblivion while pumping up meatiness (promise it won’t taste fishy). Aromatic vegetables—onion, carrot, celery—should be diced small so they soften completely and integrate into the sauce.

Fresh herbs are non-negotiable. A sturdy sprig of rosemary perfumes the whole braise; add it at the beginning so the essential oils have time to infuse. Garlic mellows beautifully over eight hours, so I leave the cloves whole and smashed. Finally, a strip of orange peel brightens the richness; if citrus isn’t your thing, substitute a bay leaf plus a strip of lemon peel for a more Mediterranean vibe.

Pantry staples finish the job: extra-virgin olive oil for searing and sautéing, flour to thicken the gravy, salt, pepper, and just a pinch of brown sugar to balance tomato acidity. If you’re gluten-free, swap the flour for 1 tbsp cornstarch whisked into 2 tbsp cold water and add it during the final reduction.

How to Make Slow Cooker Lamb Shanks for Special Occasions

Pat, season, and sear

Remove shanks from the refrigerator 30 minutes early so they cook evenly. Blot very dry with paper towels—moisture is the enemy of browning. Season aggressively on all sides with 2 tsp kosher salt and 1 tsp freshly ground black pepper. Heat 2 tbsp olive oil in a heavy skillet over medium-high heat until it shimmers. Brown two shanks at a time, turning every 2 minutes, until every surface is deep mahogany, 8–10 minutes total. Transfer to the slow-cooker insert; repeat with remaining shanks. Those caramelized bits (fond) clinging to the pan equal flavor gold—reserve the skillet for step 3.

Build the aromatic base

Reduce heat to medium and add 1 more tbsp oil to the same skillet. Stir in 1 diced onion, 2 carrots, and 2 celery stalks. Cook 4 minutes until edges begin to brown. Add 4 smashed garlic cloves, 2 tbsp tomato paste, and 1 anchovy fillet; mash everything together until the paste darkens to brick red, another 2 minutes. Sprinkle 2 tbsp all-purpose flour over the veg and cook 1 minute to remove raw taste.

Deglaze and pour

Slowly pour 1 cup dry red wine into the skillet, scraping the bottom with a wooden spoon to dissolve every browned speck. Let it bubble for 2 minutes so the alcohol cooks off, then add 1 cup chicken stock, 14-oz can crushed tomatoes (with juice), 1 tsp brown sugar, and ½ tsp each salt and pepper. Once the mixture is steaming, tip it over the waiting lamb shanks in the slow cooker. Tuck 1 large rosemary sprig and a 2-inch strip of orange peel between the shanks.

Low and slow magic

Cover and cook on LOW 8–9 hours or until meat is retreating from the bone and a fork slides in with zero resistance. If you’re running late, the keep-warm setting will hold them another hour without drying. Avoid the temptation to peek during the first 6 hours; every lift of the lid adds 15–20 minutes to the cook time.

Transfer & skim fat

Using tongs, gently lift shanks onto a platter; they’re delicate so support them underneath. Cover loosely with foil. Pour the cooking liquid into a fat-separator measuring cup, or refrigerate the sauce 15 minutes so fat solidifies on top, then spoon it off. You should have about 3 cups silky sauce.

Reduce to glossy gravy

Return the defatted liquid to a saucepan; bring to a gentle boil. Simmer 8–10 minutes until reduced by one-third and the sauce coats the back of a spoon. Taste and adjust salt. For extra shine, whisk in 1 tbsp cold butter just before serving.

Plate like a pro

Spoon a puddle of the gravy onto a warm dinner plate, center a lamb shank upright so the bone points skyward, then drizzle with a little more sauce. Garnish with fresh rosemary leaves and bright-orange zest for color contrast. Serve alongside creamy polenta, mashed parsnips, or lemony risotto to soak up every drop.

Expert Tips

Brown = flavor

Don’t crowd the pan while searing; otherwise the lamb steams. Two shanks at a time is the max for a 12-inch skillet.

Tie rosemary safely

Secure the rosemary sprig with kitchen twine; it prevents leaves from floating everywhere and makes removal easy.

Bone marrow bonus

Encourage guests to scoop out the soft marrow from the bone center—it’s pure, unctuous luxury that melts into the sauce.

Thicken shortcut

If your sauce is thin at the end, whisk 1 tsp cornstarch with 2 tsp cold water, then stir into simmering liquid for 30 seconds.

Wine swap

Prefer no alcohol? Substitute ¾ cup pomegranate juice + ¼ cup balsamic vinegar for a fruity, tangy depth.

Keep bones pristine

Wrap the exposed bone in a small piece of foil before cooking; it prevents discoloration and looks gorgeous at service.

Variations to Try

Moroccan Spiced: Add 1 tbsp ras-el-hanout, ½ cup diced dried apricots, and a cinnamon stick. Garnish with toasted almonds and cilantro.
Greek Style: Swap rosemary for oregano, use white wine instead of red, and stir in ½ cup pitted Kalamata olives during the last hour of cooking.
Smoky BBQ: Replace tomatoes with 1 cup BBQ sauce, add 1 chipotle in adobo, and finish with a drizzle of molasses for a campfire twist.
Asian-Inspired: Substitute soy sauce for half the stock, add 2 star anise, 1 thumb of ginger, and finish with sesame oil and scallions.
Vegetable Boost: Toss in 2 cups peeled pearl onions and 1 lb baby potatoes during the final 3 hours for a one-pot meal.

Storage Tips

Refrigerating: Cool the shanks in the sauce, transfer to airtight containers, and refrigerate up to 4 days. The flavors actually improve overnight as the seasonings meld. Reheat gently on the stovetop over low heat, adding a splash of stock to loosen.

Freezing: Place shanks with gravy in freezer bags, remove excess air, label, and freeze up to 3 months. Thaw overnight in the refrigerator, then reheat as above. Sauce consistency may thin slightly; just simmer 5 minutes to regain body.

Make-ahead for parties: Complete the recipe through the 8-hour slow-cook the day before. Refrigerate components separately. The next afternoon, lift off the solidified fat, reheat shanks in a 300 °F (150 °C) oven for 25 minutes, and warm sauce on the stove. You’ll have a stress-free entrée ready when guests arrive.

Frequently Asked Questions

You can, but LOW produces noticeably silkier meat. If time-pressed, use HIGH for the first hour to bring everything to temperature, then switch to LOW for 3–4 hours more.

Creamy polenta soaks up gravy like a dream. Other classics: lemon-herb risotto, garlic mashed potatoes, or crusty sourdough. For vegetables, try roasted asparagus or honey-glazed carrots.

Not at all. Substitute pomegranate juice + vinegar (see Expert Tips) or use 1 cup grape juice with 2 tsp lemon juice to mimic wine’s acidity and fruit notes.

Only if your insert is 7-quart or larger; the shanks should fit in a single layer so they braise rather than steam. Double all sauce ingredients but keep the cooking time the same.

When cooked properly, lamb shanks are rich but not gamey. The long braise mellows strong flavors, and the wine-orange-herb trio adds brightness. If you’re sensitive, trim external fat where gaminess resides.
