Melt the butter in a large pot or Dutch oven over medium heat. Cut the chicken and coat it with salt and pepper. Slice the onion. Add the chicken and onion to the pot and cook, stirring occasionally, until both begin to turn golden brown.
Add the paprika, garlic powder, and stock to the pan with the chicken, and bring to a low boil. Continue to boil until the sauce has reduced by half and begins to thicken. Add the sour cream, turn the heat to low, and simmer until the sauce thickens to your liking. Add additional salt and pepper if necessary.
