Add the chicken and a chopped onion into the tray. Add salt, black pepper, and olive oil into tray. Mix it well.
Turn on the heat. Cover the tray with foil and cook the chicken for 30 to 35 minutes.
After 15 minutes, put the chopped potatoes into the tray. Continue cooking for remaining 15 to 20 minutes.
Once the chicken is almost cooked, add tomato paste and cook for another 5 minutes.
Preheat the oven in 220 C. Transfer the chicken tray in to the top of the rack. Let it bake for 5 to 10 minutes or until you see a beautiful brown texture of the potato and chicken. Serve with rice or pita bread.
Notes
If you don’t have tomato paste, you can use tomato sauce
