Ingredients

• 4 pieces lamb shanks
• 2 tablespoons olive oil
• 2 tablespoons unsalted butter
• 3 pieces large onions
• 6 pieces garlic cloves
• 2 pieces fresh rosemary stems
• 4 pieces fresh thyme stems
• 500 milliliters beef or lamb stock
• 250 milliliters red wine
• 2 tablespoons tomato paste
• 1 teaspoon salt
• 1 teaspoon black pepper

Directions

Step 1

Preheat your oven to 160°C (325°F).

Step 2

Pat the lamb shanks dry with a paper towel and season them generously with salt and black pepper.

Step 3

In a large ovenproof pot or Dutch oven, heat the olive oil over medium-high heat. Sear the lamb shanks on all sides until browned (about 8-10 minutes). Remove the shanks and set them aside.

Step 4

Reduce the heat to medium, add the butter, and let it melt. Slice the onions thinly and add them to the pot. Cook the onions for 10-15 minutes, stirring occasionally, until they are golden and caramelised.

Step 5

Mince the garlic and add it to the pot, cooking for 1-2 minutes until fragrant.

Step 6

Stir in the tomato paste and cook for 1-2 minutes to concentrate the flavors.

Step 7

Pour in the red wine, scraping the bottom of the pot to deglaze and loosen any browned bits.

Step 8

Add the rosemary, thyme, beef or lamb stock, and stir to combine. Bring the mixture to a simmer.

Step 9

Return the seared lamb shanks to the pot, ensuring they are partially submerged in the liquid. Cover the pot with a lid or foil and transfer it to the preheated oven.

Step 10

Roast the lamb shanks in the oven for 2.5 to 3 hours, turning them halfway through, until the meat is tender and falling off the bone.

Step 11

Remove the pot from the oven and carefully transfer the lamb shanks to a serving plate. Discard the rosemary and thyme stems from the sauce.

Step 12

Simmer the remaining liquid on the stovetop over medium heat for 10-15 minutes to reduce and thicken if needed.

Step 13

Serve the lamb shanks with the caramelised onion sauce drizzled on top. Pair with mashed potatoes or crusty bread for the ultimate comfort meal.
