With chicken remove the skin and cut into portions pieces.

Onion cut into half rings and sent it to chicken. Add sour cream, mustard and 1-2 teaspoons of ground coriander. Salt. Stirred well so that each piece was coated evenly and put in the fridge for an hour or two or five. As it will turn out. I usually lunch, marinated, and how to work in the evening coming, is already in the oven chicken to send.

Marinated chicken spread in a baking dish. And - in a preheated 180 degree oven for 40 minutes.

Now important point. After 40 minutes, I cover the chicken with foil and leave in turned-off oven for 20 minutes. This is to ensure that the onion managed to "walk" and become soft.
