Assemble ingredients.
Preheat oven to 180°C fan forced 200°C conventional.
Heat a 4 litre capacity flameproof casserole on medium heat. Add cumin and coriander seeds to the pan and swirl the pan gently.
Remove from the pan when the seeds become fragrant and cool on a dish.
Grind the seeds with a mortar and pestle and add cinnamon and set aside.
Crush saffron in the mortar and pestle and scrape into a small bowl. Add a tablespoon of warm water to infuse the saffron, set aside.
Remove lemon segments from preserved lemons and rinse under cold water. Pat dry with paper towels and set aside.
Slice the lemon quarters across into strips approximately 4-5mm wide. Set aside.
Peel the garlic and set aside.
Split the chillies lengthwise down the middle, removing the membrane and seeds with a small paring knife. Slice the halves crosswise into 3-4mm strips. Set aside.
Remove the roots from the fresh coriander and discard. Cut the coriander stems from the leaves and reserve the leaves in the fridge to garnish the finished dish. Chop the stems finely and set aside.
Peel the onions, halve and cut them into segments about 2cm thick.
Remove the core and seeds from the capsicum. Roughly chop the capsicum into large pieces.
Add a couple of tablespoons of oil to the pan on medium high heat. Brown the chicken on both sides in batches, don’t crowd the pan. Set aside each batch on paper towels to absorb any excess oil. Set aside.
Add another tablespoon of oil to the pan, swirl and add the chopped onions and capsicum. Leave without stirring to get some char happening on the edges of the vegetables. Stir them for a few minutes and remove from heat before they start to soften. Set aside.
Add another tablespoon of oil to the pan, and heat on medium heat. Add the ground spice mix, crushed or chopped garlic, sliced chillies, bay leaves, and chopped coriander stems. Stir until the spices become aromatic, then add the rice and stir well to coat the rice with the flavoured oil.
Add the wine to the pan and stir to deglaze.
Add the chicken stock and saffron water to the pan and stir.
Drain the tinned chickpeas, discarding the fluid. Add the chickpeas and stir to distribute them across the pan.
Then add the onions and capsicum to the pan, pushing them into the rice part away.
Add the strips of preserved lemon rind and the green olives across the top of the rice mixture, pushing them in lightly.
Place the chicken, skin side up, on top of the rice base (do not press into the rice). If necessary, the chicken pieces can overlap slightly but the goal is for them to cook in a single layer.
Cover pan with a tight fitting lid or cover with foil. If your lid is a bit loose, you can cover the pan with foil or baking paper first and then put the lid on.
Bake for approximately 1 hour. Check at 45 minutes to see if the rice is cooked through. It will expand quite a bit, be soft, and have absorbed all the liquid. If the rice is not quite cooked and the liquid has all absorbed, add a small amount of chicken broth, wine or water. Cover and return to the oven until the rice has finished cooking.
The chicken will be fully cooked at this stage. You can check a piece to make sure there is no blood near the bone or use an instant read thermometer, which should read a minimum of 74°C.
Assemble the garnishes before serving. Cut lemon wedges and chop the coriander leaves coriander leaves. Place the Greek yoghurt in a serving bowl and drizzle some extra virgin olive oil.
Serve the Moroccan chicken bake straight from the oven or keep covered and warm until ready to serve.
