Heat the olive oil in a cast iron skillet over medium high heat. Add the chicken, sear on both sides until browned.
In a bowl stir together the basil, rosemary, mustard, sour cream, lemon juice, honey, and garlic powder, set aside.
Pour the beer into the skillet, scraping to deglaze the bottom of the pan.
Pour the sour cream mixture over the chicken, cover skillet and lower heat to maintain a simmer. Simmer until slightly thickened, about 5 minutes.
