Step 1

Heat 2 tablespoons oil in a flame-proof casserole or heavy-based pan over medium-high heat. Season lamb, then brown for 5 minutes, turning, until sealed on all sides. Remove and set aside. Add pancetta and cook, stirring, for 3-4 minutes until crisp. Add onion, garlic and rosemary, season, then cook for 3-4 minutes. Add paste, bay leaves and thyme sprigs, stir for 1 minute, then add wine and simmer over medium-high heat until reduced by half. Add stock and lamb. Cover surface closely with a sheet of baking paper, then simmer on very low heat for 2 1/2-3 hours until lamb is very tender.

Step 2

Meanwhile, heat a little extra oil in a pan on medium-high heat. Brown sausages for 3-4 minutes. Remove, then slice 2cm thick (they'll finish cooking in the sauce.)

Step 3

Remove lamb shanks from pan. Skim excess fat from sauce, then boil over medium heat for 3-4 minutes until reduced. Reduce heat to medium-low, add beans and sausages, then simmer for 10 minutes or until sausage is cooked. Return lamb to pan to warm through. Keep warm.

Step 4

Meanwhile, melt butter in a pan over medium heat, add breadcrumbs and chopped thyme and cook, stirring, for 3-4 minutes until crisp. Stir in parsley. Serve cassoulet with herb crumbs.
