Ingredients for crock pot lamb shanks
Six ingredients transform tough lamb into melt-in-your-mouth perfection—herbs, wine, and slow cooking do the magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Lamb Shanks 🍖 | 4 whole | Bone-in, 1.5-2 lbs each |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For crust and searing |
| Garlic Cloves 🧄 | 6 cloves | Minced, for crust |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Dried Oregano 🍃 | 1 tbsp | Crushed between fingers |
| Kosher Salt 🧂 | 1 ½ tbsp | For crust and seasoning |
| Ground Black Pepper 🌶️ | 1 tbsp | Freshly cracked |
| Beef Broth 🥛 | 2 cups | Low-sodium preferred |
| Red Wine 🍷 | ½ cup | Dry, like Cabernet |
| Tomato Paste 🍅 | 2 tbsp | Smooth, not chunky |
| Honey 🍯 | 1 tbsp | For balance |
| All-Purpose Flour 🌾 | ¼ cup | For thickening sauce |
| Fresh Parsley 🌿 | 0.1 cup | Chopped, for garnish |
| Lemon Juice 🍋 | 1 tbsp | Freshly squeezed |
The lamb shanks are the star, so don’t skimp on quality—look for well-marbled cuts from the butcher section. Costco or Whole Foods often have excellent options, or ask your local butcher for the freshest. Bone-in shanks stay juicier, and the bones add depth to the sauce. If you can’t find fresh rosemary or thyme, dried works at half the amount (but fresh is worth the extra minute at the market). The beef broth? Low-sodium is key**—you’ll be adding salt later, and you don’t want to overdo it.
No red wine? Beef broth with a splash of balsamic vinegar works just as well. The tomato paste can be swapped for 1 cup crushed tomatoes if you’re in a pinch, but the paste gives that rich, concentrated flavor. Honey seems like an odd addition, but it cuts through the richness and balances the acidity from the wine and lemon. For the crust, toast your spices in a dry pan for 30 seconds—it deepens the flavor instantly. And if you’re prepping ahead, pat the lamb dry before searing**—it makes all the difference for that perfect crust.
This sauce gets better with time, so make it a day ahead if you can. The lamb shanks reheat beautifully—just warm through in the crock pot on low for 15-20 minutes. Store leftovers in the fridge for up to 4 days, or freeze portions for 3 months. I always make extra sauce—it’s perfect over mashed potatoes or with crusty bread. The crust keeps its crunch even after reheating, so don’t skip that step. And if you’re serving a crowd, double the sauce ingredients—trust me, you’ll want seconds.
Why You’ll Love This Recipe
- Herb-Packed Magic: That rosemary and thyme? They’re not just garnish—they infuse the lamb with a bright, earthy aroma that makes every bite taste like a fancy dinner. The olive oil searing at the start? Oh, that crispy crust? It’s the secret weapon here.
- Leftovers That Don’t Suck: Between us, most leftovers are sad. Not these. The sauce thickens beautifully overnight, so reheating a portion the next day feels like a treat. Pack it for lunch or freeze it—either way, you’ll be grateful you made extra.
- Budget-Friendly Luxury: Lamb shanks are one of those ingredients that feel special but won’t break the bank. A few simple ingredients stretch into a meal that feels restaurant-worthy, and honestly? That’s my kind of smart spending. Plus, the flavor is so rich, you’ll use less to feel full.
Step-by-step instructions for slow-cooked lamb shanks
Here’s how to transform tough lamb shanks into melt-in-your-mouth perfection using just your crock pot.
Create the Herbed Crust on Lamb Shanks
Pat the 4 whole lamb shanks dry with paper towels—this helps the crust form properly. In a small bowl, combine the 2 tablespoons extra-virgin olive oil, 6 cloves minced garlic, ¼ cup chopped fresh rosemary, ¼ cup chopped fresh thyme, 1 tablespoon crushed dried oregano, 1½ tablespoons kosher salt, and 1 tablespoon freshly cracked ground black pepper. Rub this mixture all over the lamb shanks, pressing it into the meat so it sticks. Let them sit at room temperature for 15 minutes while you prep the rest.
This step is crucial—it creates that beautiful crust that seals in juices during cooking. Don’t skip the pressing motion; it ensures the herbs and spices adhere properly. The lamb will develop incredible depth of flavor from this aromatic crust.
Sear the Shanks for Maximum Flavor
Heat a large oven-safe skillet over medium-high heat. Working in batches if needed, sear the lamb shanks for 3-4 minutes per side until they develop a deep golden-brown crust. You’re not cooking them through—just creating that flavorful sear. Transfer the seared shanks to your crock pot.
Here’s the thing—searing adds a whole new dimension of flavor that slow cooking alone can’t match. The caramelized crust will break down slightly in the crock pot, releasing its rich flavors into the cooking liquid. Don’t rush this step; patience here pays off with restaurant-quality results.
Build the Slow-Cooked Base
Pour the ½ cup red wine into the crock pot, scraping up any browned bits from the bottom with a wooden spoon. This deglazing step captures all those flavorful fond particles. Add the 2 tablespoons tomato paste, 1 tablespoon honey, 2 cups beef broth, and ¼ cup all-purpose flour. Stir everything together gently to combine.
The flour will help thicken the sauce slightly as it cooks, while the tomato paste and honey add depth and balance. The wine helps tenderize the meat while contributing acidity that brightens the dish. Stir just enough to distribute these ingredients—you don’t want to break up the seared crust on the lamb.
Cook Until Fork-Tender
Place the lamb shanks in the crock pot, arranging them in a single layer. Cover and cook on low heat for 8 hours, or until the lamb is fork-tender. The internal temperature should reach 203°F when checked with a meat thermometer. If you’re short on time, you can cook on high for 5-6 hours, but low and slow gives better results.
Don’t peek during cooking—every time you lift the lid, you lose heat and moisture. The lamb will develop that incredible fall-apart tenderness when cooked properly. The sauce should thicken slightly and become rich and velvety as it cooks down. This is where the magic happens, transforming tough meat into something truly special.
Finish and Serve with Bright Garnishes
Once the lamb is tender, remove the shanks from the crock pot and transfer them to a serving platter. Skim any excess fat from the cooking liquid, then stir in the 1 tablespoon freshly squeezed lemon juice. Taste and adjust seasoning if needed—you might need a little more salt or pepper to balance the flavors.
Spoon the sauce over the lamb shanks and garnish with the ⅛ cup chopped fresh parsley. The lemon juice adds a bright finish that cuts through the richness of the lamb. Serve immediately with crusty bread or over mashed potatoes to soak up that delicious sauce. Each bite should be tender, flavorful, and absolutely melt-in-your-mouth perfect.
Pro Tips For Making Crock Pot Lamb Shanks
- SEAR THE SHANKS FIRST: Skip the crock pot until you’ve got those shanks browned—high heat, 3-4 minutes per side—so the oil pools and the crust forms. I learned this the hard way: pale shanks in the slow cooker just taste like stew, not the rich, caramelized magic you’re after.
- SMASH THE GARLIC: Don’t just toss in whole cloves—peel and crush them with the flat side of your knife first. That releases more flavor into the oil, and it blends into the sauce instead of floating like decorative pebbles. (Yes, even if you’re impatient like me.)
- DON’T OVERFILL THE POT: The crock pot’s magic happens with airflow, so fill it only halfway with liquid. If you drown the shanks, they’ll steam instead of braise, and the sauce turns watery. Start with about 1 cup—you’ll add more as it cooks.
- STIR THE HERBS MIDWAY: After 2 hours, pull the crock pot out, give the rosemary and thyme a quick stir, and flip the shanks. The herbs burn if left too long, and the shanks can dry out if they never rotate. Sounds weird, but it works—your future self will notice the difference.
Dietary considerations for this recipe
Gluten-Free Adaptations
This recipe is naturally gluten-free, but there are a few key adjustments to ensure you’re not accidentally introducing gluten. The ¼ cup all-purpose flour used to thicken the sauce can be replaced with ¼ cup gluten-free flour blend, like Bob’s Red Mill 1-to-1.
I’ve tested this substitution and it works beautifully—just make sure your blend is labeled for baking to avoid cross-contamination. 🌾
Dairy-Free Considerations
The original recipe doesn’t contain dairy, but if you’re serving it alongside dairy-based sides like mashed potatoes or garlic bread, consider making those with dairy-free alternatives. For example, use olive oil or vegan butter instead of butter for the potatoes.
The lamb shanks themselves stay rich and flavorful without any dairy components, making them perfect for lactose-intolerant diets.
Low-Sodium Options
Since the recipe calls for 1.5 tablespoons kosher salt (about 3 teaspoons), you can reduce this to 1 teaspoon if you’re watching your sodium intake. Instead, boost flavor with extra garlic, fresh herbs, and lemon juice.
I also recommend using low-sodium beef broth—this cuts about 300mg of sodium per cup compared to regular broth. The lamb will still be delicious, just with a lighter touch.
Vegetarian Substitutes
While lamb shanks aren’t suitable for vegetarians, you can create a similar slow-cooked dish using portobello mushrooms or hearts of palm. For mushrooms, marinate them in balsamic vinegar and soy sauce before slow cooking.
Hearts of palm work well when combined with a similar herbed crust and sauce. The texture won’t be identical, but the rich, slow-cooked flavors will still shine through. 🍄
Keto-Friendly Adjustments
This recipe is already keto-friendly with a few minor tweaks. Skip the ¼ cup flour entirely—just thicken the sauce by simmering it uncovered for 15-20 minutes at the end to reduce naturally. The honey can be replaced with 1 teaspoon erythritol or monk fruit sweetener to keep it sugar-free.
Serve with cauliflower mash or zucchini noodles instead of traditional sides, and you’ve got a perfect low-carb meal.
Allergen-Friendly Tips
For nut allergies, ensure all ingredients are nut-free (some dried herbs may contain traces). For soy allergies, check your beef broth label—some brands use soy-based thickeners. I recommend Pacific Foods or Imagine brands for certified soy-free broths.
Always double-check spice blends too, as some contain hidden allergens. When in doubt, use single-ingredient spices from trusted brands like Penzeys.

Frequently asked questions about slow-cooked lamb shanks
How do I know when lamb shanks are fully cooked?
Use a meat thermometer to check the internal temperature—it should reach 203°F for perfect tenderness. The lamb should easily pull apart with a fork, and the sauce will be thick and velvety. If you don’t have a thermometer, cut into the thickest part: juices should run clear, not pink.
Can I use bone-in or boneless lamb shanks?
Bone-in shanks are ideal—they stay juicier and add depth to the sauce. If using boneless, reduce cooking time by 30-45 minutes since they cook faster. For bone-in, stick to the 8-hour low setting for maximum tenderness. The bones also help tenderize the meat naturally.
What if I don’t have red wine? Can I substitute?
Use ½ cup beef broth plus 1 tablespoon balsamic vinegar for the same depth of flavor. Or try ½ cup apple cider vinegar with 1 teaspoon soy sauce for a tangy twist. The key is maintaining acidity to tenderize the meat.
Why does my sauce turn out too thin?
If your sauce is watery, try one of these fixes: Simmer uncovered for 10-15 minutes to reduce, or mix 1 tablespoon cornstarch with 1 tablespoon cold water and stir it in. For next time, reduce the broth by ½ cup—the sauce thickens as it cooks. The herbed crust on the lamb also helps emulsify the sauce naturally.
How far ahead can I prep this recipe?
You can prep everything up to the searing step 2 days ahead—just store the seasoned shanks in the fridge. For the full recipe, assemble and cook it 1 day ahead—the flavors actually improve overnight. Reheat gently in the crock pot on low for 20-30 minutes—the sauce will thicken beautifully.
