Prepare the marinade in advance, the day before if possible, with half the olive oil, powdered ginger, coriander seeds, paprika, curry, cinnamon, salt and pepper.
The next day, brown the tagine chicken thighs in the oil and marinade until they are nicely browned. Add the sliced onions and crushed garlic.
Let the onions brown, add the roughly chopped zucchini and carrots and simmer for 10 minutes over low heat.
Cook covered for another 20 minutes over low heat, then add the olives and the lemon cut into quarters.
Cook over low heat for another 1 hour (2 in my case…)
Serve hot and sprinkle with fresh cilantro.
