Cut up the chicken and remove the skin. Make several cuts in chicken to allow sauce and flavors to seep inside. Rub chicken with some olive oil, salt, and baharat. Peel potatoes and cut into disks. Salt slightly. Peel carrots and zucchini and cut into circles or stems. In a pot, add 1 tbsp of olive oil and slightly brown cut potatoes. Remove and set aside. Peel and cut onion. In the same pot, add more olive oil (if needed) and brown onion until it's soft. Then add crushed garlic. After 30 seconds, add chicken to brown slightly. Put all ingredients in an oven-proof dish, adding chicken with onion and garlic to the bottom, potatoes with the rest of the vegetables used to the top. Put the dish in a preheated oven and bake at medium heat for about 20 to 25 minutes. Place under the broiler to brown the top for about 5 minutes.
