Preheat the oven to 150°C fan. Season the lamb shanks. Heat a large casserole with a little oil and sear the shanks on all sides until well browned. Remove and set aside

Lower the heat and add the butter. Once melted, add the sliced onions, brown sugar and thyme. Cook gently for 20-25 minutes, stirring occasionally, until the onions are very soft and caramelised. Add the garlic and cook for 1 more minute, then pour in the white wine and simmer for a few minutes

3

Return the seared shanks to the pot, pour in the stock and add the bay leaves. Bring to a gentle simmer

4

Cover and cook in the oven for 3 hours to 3 hours 30 minutes, or until the lamb is falling off the bone

Spread the baguette slices with butter and top with the grated Gruyère. Grill until melted and golden
