Ingredients
Lamb Shanks - The hero ingredient, known for its tenderness when cooked slowly. Substitute: beef shanks for a different but equally rich flavor.
Red Wine - Adds depth and richness to the sauce. Substitute: beef broth with a splash of balsamic vinegar for a non-alcoholic option.
Garlic - Provides a robust flavor that complements the lamb. No real substitute captures its unique taste, but a tiny amount of garlic powder can be used in a pinch.
Rosemary - Its aromatic quality enhances the meat's flavor. Substitute: dried rosemary if fresh is not available, but use less as it's more potent.
Tomatoes - Break down during cooking to create a rich, thick sauce. Substitute: canned tomatoes if fresh ones aren’t in season.
Tips
- Brown the lamb shanks before adding them to the slow cooker to add a rich flavor to the dish.
- Deglaze the pan with red wine after browning the meat to capture all the flavorful bits.
- Layer the garlic and rosemary under and over the lamb shanks in the slow cooker to evenly distribute the flavors.
- Cook on low for a longer period rather than on high for a shorter time to ensure the lamb is tender and flavorful.
- Let the dish rest for a few minutes after cooking to allow the sauce to thicken slightly.

How to Serve
Slow cooker lamb shanks are a luxurious and comforting meal, perfect for chilly nights or special occasions. The meat becomes so tender that it falls off the bone, and the sauce created during the slow cooking process is rich and flavorful.
- With Mashed Potatoes: Serve the lamb shanks on a bed of creamy mashed potatoes to soak up the delicious sauce.
- Over Polenta: Polenta provides a smooth and creamy base that complements the rich flavors of the lamb and sauce.
- Alongside Roasted Vegetables: Roast a mix of your favorite vegetables like carrots, potatoes, and onions to serve as a healthy and colorful side.

FAQs
Can I skip browning the lamb first?
Yes, but it’s not recommended. Browning adds a lot of flavor and color. If you skip it, the dish will still cook fine but won’t taste as rich.
Can I cook this on high instead of low?
Yes, cook on high for about 4–5 hours. The lamb will still get tender, but low heat gives a softer texture and better results overall.
What can I use instead of red wine?
You can use extra beef broth instead. Adding a splash of balsamic vinegar or a little lemon juice can help replace some of the depth the wine adds.
How do I store and reheat leftovers?
Store in the fridge for up to 3 days in a sealed container. Reheat gently on the stovetop or in the microwave, adding a little broth if the sauce thickens too much.
Can I make this in the Instant Pot?
Yes, it works well. Use the sauté function to brown the lamb and cook the vegetables first. Add the liquids, then pressure cook on high for about 40 minutes with natural release. If you want a full step-by-step version, check out my Instant Pot lamb shanks recipe as an alternative method.

Notes
- Brown the lamb well before slow cooking, this step adds a lot of flavor and gives the final dish a deeper, richer taste.
- Don’t rush the cooking time, low and slow is what makes the meat tender enough to fall off the bone.
- If the sauce feels too thin at the end, remove the lid and cook on high for 20–30 minutes to reduce it.
- Skim off excess fat from the top before serving if needed, since lamb can release quite a bit during cooking.
This recipe is so so good. I never thought I could recreate the lamb dish I have at our fav Greek restaurant. I was wrong. Oh course you have to like lamb. Kind of dark and heavy, but when cooked like this.... yum yum yum
Thus sounds so delicious. What makes the Potassium and sodium so HIGH? Can't make it for this reason.
Hello! Not sure about the potassium but the high sodium might be due to the beef broth; you could substitute sodium free broth.
That said, Corrie might come back with a different answer.
