Prepare everything you need. Rinse the thighs, pat dry with a paper towel to remove excess moisture.
Sprinkle with salt and pepper, mix. Leave to marinate for up to a day. The longer, the better. But you can continue right away.
1 kg chicken thigh, ¼ tsp salt, 1 pinch pepper
On a heated skillet with oil, place the onion slices. Fry until translucent, remove to a plate.
150 g yellow onion, 1 tbsp vegetable oil
Heat the same skillet, place the thighs skin side down. Try not to fill the entire surface at once, otherwise the chicken may start to stew. Fry over high heat, turn after 5 minutes. Remove the cooked ones if necessary and add a new batch.
Return all the thighs to the skillet, if the height allows, you can stack them in several layers. Distribute the onion on top. Pour in half of the water, cover with a lid and simmer over low heat for 15 minutes.
500 ml water
Separately, mix sour cream, starch, turmeric, and the remaining water. There should be no lumps of starch. Pour in the sour cream-starch mixture, turn the chicken over, thus stirring the sauce and preventing the starch from thickening quickly.
100 g sour cream, 1 tsp starch, ¼ tsp turmeric, 500 ml water
Turn the thighs back after 2 minutes.
Sprinkle with chopped garlic, herbs as desired. Let it sit covered for a couple of minutes. Chicken thighs in sour cream in a skillet are ready. Serve with mashed potatoes or boiled rice as a side dish.
