Instruction Guide

Here’s a step-by-step guide to turn those raw lamb shanks into a melt-in-your-mouth meal:

1. Prep The Ingredients

   • Chop your vegetables into large chunks-they’ll cook down beautifully without turning to mush.
   • Pat the lamb shanks dry with paper towels to ensure they brown properly.

2. Brown The Lamb Shanks

   • Heat olive oil in a skillet over medium-high heat.
   • Sear lamb shanks on all sides until golden brown-this adds flavor depth.
   • Transfer shanks to the slow cooker.

3. Sauté The Aromatics

   • In the same skillet, sauté onions, carrots, and celery for 5-7 minutes until softened.
   • Add garlic and tomato paste, cooking for another 1-2 minutes to release the aroma.

4. Deglaze The Pan

   • Pour in red wine, scraping up any browned bits from the skillet-they’re full of flavor!
   • Allow wine to reduce slightly before transferring it to the slow cooker.

5. Combine Ingredients In The Slow Cooker

   • Add diced tomatoes, broth, herbs, and bay leaves to the slow cooker.
   • Nestle the lamb shanks among the vegetables and liquid.

6. Slow Cook

   • Cover and cook on low for 7-8 hours or on high for 4-5 hours.
   • Check for tenderness-the meat should practically fall off the bone.

7. Finish And Serve

   • Remove the lamb shanks and vegetables.
   • Optional: Reduce the cooking liquid on the stovetop to thicken into a rich sauce.
   • Serve with mashed potatoes, polenta, or crusty bread, spooning sauce generously over everything.

Ingredient Swaps

Sometimes you don’t have everything on hand-or you want to experiment:

• Red Wine – Substitute with more broth plus a splash of balsamic vinegar for depth.
• Beef Broth – Chicken or vegetable broth works if you prefer a lighter flavor.
• Carrots/Celery – Parsnips, turnips, or bell peppers can replace or complement.
• Fresh Herbs – Dried rosemary and thyme are fine, but reduce quantities slightly (1 tsp each).
• Diced Tomatoes – Tomato sauce or crushed tomatoes can be used for a smoother texture.

Helpful Tips

Here are some insider secrets to elevate your slow-cooked lamb shanks:

• Don’t skip browning the meat – It makes a world of difference in flavor.
• Layer your flavors – Sautéing vegetables and using wine helps create a richer sauce.
• Use bone-in shanks – The marrow adds natural richness to the sauce.
• Resist over-stirring – Slow cooking is gentle; stirring too often can make the meat dry.
