Season your chicken with salt and pepper on both sides. Heat up a skillet, add cooking oil and sear the chicken in batches, until nicely brown. Do not overcrowd the chicken and use a splatter guard if the chicken is splashing around (tip: place chicken skin side down and do not disturb for 6-7 minutes, then flip and cook for 3-4 minutes on the other side; this will ensure a nice sear on the skin).

Chop your onions and garlic. Once the chicken is seared on both sides, remove it to a plate and add onions into the same pan (if too much fat has accumulated in a skillet, remove some of it so you are left with approx 1 tablespoon of fat). Saute onions until translucent, for about 5 minutes.

Add garlic and cook for one minute. Then add flour to the skillet and cook for 2 minutes. Then add paprika & tomato paste and mix well.

Then add chicken broth and place chicken back into the skillet. Cover it and cook for about 20 minutes, until chicken is fully cooked through. Once the chicken is cooked, remove it from the skillet so you can finish up the sauce.

 Prepare the roux: combine sour cream with flour and a splash of water. Start gradually adding a little bit of sauce to it to temper it until you have a full cup. Then pour it over the sauce and let it come to a boil.
