Easy Slow Cooked Lamb Shanks NZ Recipe

This is a recipe that practically cooks itself. The trick is to let the lamb shanks simmer gently for hours until the meat is tender, flavorful, and practically falling off the bone. Here’s what you’ll need and how to make it happen.
Ingredient List
For a classic, hearty New Zealand-style lamb shank dish:
- 4 New Zealand lamb shanks (about 1-1.2 kg each)
- 2 tablespoons olive oil
- 1 large onion, roughly chopped
- 3 garlic cloves, crushed
- 2 carrots, cut into chunks
- 2 celery sticks, chopped
- 1 cup red wine (optional but recommended for depth)
- 2 cups beef or lamb stock
- 2 tablespoons tomato paste
- 2 teaspoons fresh rosemary, chopped (or 1 teaspoon dried)
- 2 teaspoons fresh thyme leaves (or 1 teaspoon dried)
- 2 bay leaves
- Salt and pepper, to taste
- Optional: a handful of chopped parsley for garnish
Instruction Guide
Let’s break this down step by step. I’ll keep it conversational, like we’re cooking together:
- Prep the lamb: Pat the shanks dry with a paper towel. This is key because if they’re too wet, they won’t brown properly. Sprinkle generously with salt and pepper.
- Brown the shanks: Heat olive oil in a large, heavy-bottomed pot or Dutch oven over medium-high heat. Sear each shank for 3-4 minutes per side until golden brown. Remove and set aside.
- Sauté the aromatics: In the same pot, add onions, carrots, and celery. Cook for 5-7 minutes until softened and fragrant. Toss in garlic, rosemary, and thyme for the last minute.
- Deglaze: Pour in the red wine, scraping up those delicious browned bits at the bottom. Let it simmer for 2-3 minutes to reduce slightly.
- Add liquids and shanks: Stir in tomato paste, then add the stock. Return the lamb shanks to the pot, making sure they’re partially submerged. Throw in the bay leaves.
- Slow cook: Bring to a gentle simmer, then cover and reduce heat to low. Cook for 3-4 hours, turning occasionally, until the meat is tender and falling off the bone.
- Finish and serve: Taste the sauce and adjust seasoning with salt and pepper. Serve the shanks hot with the sauce spooned over, garnished with fresh parsley.
Ingredient Swaps
Sometimes you need to get creative with what’s in the pantry. Here are some easy swaps:
- Red wine: Use extra stock or a splash of balsamic vinegar if you prefer alcohol-free.
- Stock: Chicken stock works in a pinch, but beef or lamb stock gives the richest flavor.
- Herbs: Sage, oregano, or marjoram can replace rosemary and thyme for a different flavor profile.
- Vegetables: Parsnips, sweet potatoes, or mushrooms add depth and sweetness.
Helpful Tips
Here’s where I get a little nerdy about making your lamb shanks perfect:
- Browning is everything: Don’t skip this step-it locks in flavor and gives the sauce a beautiful color.
- Low and slow: Patience is key. Resist the urge to crank the heat; the meat will thank you.
- Check liquid levels: Make sure the shanks stay partially submerged. Add a splash of water or stock if it evaporates too quickly.
- Rest before serving: Letting the meat rest for 5-10 minutes allows juices to redistribute.
Customization Ideas
You can make this recipe uniquely yours:
- Spicy kick: Add a pinch of chili flakes or a diced fresh chili while sautéing aromatics.
- Mediterranean twist: Add olives, sun-dried tomatoes, and a splash of lemon juice at the end.
- Slow cooker version: Follow steps 1-4, then transfer everything to a slow cooker and cook on low for 6-8 hours.
- Mash it up: Serve over creamy mashed potatoes, polenta, or buttered noodles for ultimate comfort.
FAQs
What Cut Of Lamb Is Best For Slow Cooking In New Zealand?
Lamb shanks are ideal for slow cooking because they contain connective tissue that breaks down during long cooking, resulting in tender, flavorful meat. In New Zealand, fore or hind shanks from locally farmed lamb are commonly used.
How Long Should I Slow Cook Lamb Shanks?
For tender results, slow cook lamb shanks for 3 to 4 hours on low heat in a slow cooker or 2.5 to 3 hours in the oven at 160°C (320°F). The meat should be fall-off-the-bone tender when done.
Can I Use A Slow Cooker Or Do I Need The Oven?
Both methods work well. A slow cooker is convenient for hands-off cooking, while the oven allows for a richer crust if you sear the shanks first and braise them in a covered dish.
Should I Sear Lamb Shanks Before Slow Cooking?
Searing the shanks before slow cooking is recommended. It caramelizes the surface, enhancing flavor and color. Brown each side for 3-4 minutes before transferring to the slow cooker or braising liquid.
What Vegetables Go Well With Slow-cooked Lamb Shanks?
Root vegetables like carrots, parsnips, and potatoes, as well as onions, garlic, and celery, complement lamb shanks. Adding herbs such as rosemary, thyme, and bay leaves enhances the dish.
What Liquids Can I Use For Braising Lamb Shanks In NZ?
Common liquids include red wine, beef or chicken stock, or a combination of stock and canned tomatoes. In New Zealand, using a local Pinot Noir or Shiraz adds a regional touch to the recipe.
Can I Prepare This Dish Ahead Of Time?
Yes, slow-cooked lamb shanks often taste even better the next day as the flavors meld. Store in an airtight container in the fridge for up to 2 days or freeze for up to 3 months.
How Do I Thicken The Sauce After Slow Cooking?
Remove the shanks and simmer the cooking liquid uncovered to reduce it. Alternatively, mix a small amount of cornflour (cornstarch) with cold water and stir it in to achieve a thicker consistency.
What Are Common Seasonings Used In An NZ-style Lamb Shank Recipe?
Typical seasonings include salt, black pepper, garlic, fresh rosemary, thyme, and bay leaves. Some recipes also add a touch of Worcestershire sauce or mustard for depth of flavor.
Can I Make This Recipe Gluten-free?
Yes. Ensure that any stock, Worcestershire sauce, or thickening agents used are gluten-free. Cornflour is a safe gluten-free option to thicken the sauce.
