- Heat a non-stick skillet and melt in the butter quickly and lightly.
- Brown the chicken, then place it in the crockpot.
- In a bowl, pour the wine, soup, and mushrooms and stir to combine.
- In another small bowl, whisk the sour cream and flour together.
- Add soup mixture and stir to combine.
- Pour all that over the chicken breasts and cook on low in the crockpot for about 8-hours.
Serve the contents from the crockpot over a bed of egg noodles, or rice. (I actually prefer the egg noodles.)
