@msolga,
Here it goes...
800 gram chicken (any form you like either breasts, legs, etc. - if you don't eat the skin, remove beforehand)
300 gram onions, diced or in rings
2 lb. Tomatoes diced - best from the can
4 tblsp olive oil
2 tlbsp. cinnamon (you can take a bit more if you like)
2 tblsp. tomato paste
1/4 litre whipped cream
pepper, salt, and a bit of sugar to taste
8 tblsp. EL Noilly Prat vermouth (I omitted that as I had none at the house and it was fine)
Clean the chicken and season it with pepper and salt and brown in in a pan with olive oil for 5 min each side. Take the chicken out, cover all pieces evenly with cinnamon and set it aside.
Add the onions to the pan and cook them until tender, add the tomatoes, tomato paste and let it cook on high for a few minutes. Season with pepper, salt and a bit of sugar to taste and let it cook for a while longer until the sauce thickens. Reduce the heat and add the whipped cream and the vermouth (if you want to).
The sauce should be thick and creamy, that's important.
Give the chicken into an oven proof dish, add the sauce on top and bake it in the oven for 20 - 30 min. or until the chicken is done. Enjoy!
