Marinade: make the marinade by combining the olive oil, lemon juice, lemon zest, honey, dried herbs, salt and pepper in a small bowl. Use a mini whisk to stir and combine. Then set aside.
Lamb shanks: remove the packaging from the ribs and pat them dry with paper towel. Place them into a large mixing bowl.
Marinate: pour the combined lemon honey herb marinade over the top of the shanks. Use kitchen tongs to rotate and mix the shanks in with the marinade so they are completely covered. Then place cling film over the top and marinade for a minimum of 30 minutes to overnight.
Preheat the oven: preheat the oven to 180°C / 350-375°F / Gas Mark 4-5.
Baking tray: spray a large baking dish with olive oil spray then remove the marinated lamb shanks from the refrigerator and transfer them and the remaining liquid into the dish.
Oven bake: cover the baking dish with aluminium foil and place the shanks into the oven on the middle shelf. Allow them to bake for 1 hour. Then remove using oven mits, rest the dish on a heat proof surface, pull the foil off and use kitchen tongs to rotate the shanks to the other side. Use a pastry brush to scoop the marinade from the bottom of the pan, coat each top side with the marinade, then recover with foil and place back into the oven for a further hour. Then remove and repeat the rotate and baste process before putting the shanks back into the oven for the final hour.
Polenta (optional): read and follow the instructions on the packet to cook the polenta. Ensure it is seasoned with a generous sprinkle of cooking salt. Minutes before it is ready add a knob or 2 of butter and stir till melted into the polenta.
Olive mixture (optional): add the chopped artichokes, sliced kalamata olives and capers to a mixing bowl. Use a spoon to stir and combine.
Grill: use kitchen tongs to transfer the cooked lamb shanks to a lined (silicon mat) baking tray). Change the oven setting to grill at 200°C 392°F6. Place the baking rack into the oven on the top shelf. Grill the shanks for 10 mins (no need to flip). Then remove, repeat basting process followed by 10 mins grill time. Note 2.
Serve: scoop spoonful's of the cooked polenta into bowls, top with the olive mixture and place a shank on top. Drizzle Worcestershire sauce over the top and season with cracked pepper before providing a generous sprinkle of finely chopped parsley.
