Season 4 boneless skinless chicken breasts or 4 boneless skinless chicken thighs with 1/8 teaspoon kosher salt and 1/4 teaspoon ground black pepper.
In a 12-14-inch heavy skillet, preferably cast iron or stainless (NOT nonstick), heat 1 1/2 tablespoons olive or canola oil over medium-high heat.
Add the chicken and sear until well browned on both sides for 3-4 minutes per side for the breasts, 2-3 minutes for the thighs.
Transfer the chicken to a plate and tent with foil. NOTE: For Bone-In Breasts and Thighs: Follow step 1, but instead of removing the chicken to a plate, transfer the chicken to a baking sheet. Roast the chicken at 375ºF for about 10-15 minutes until chicken is cooked through. Add back to the skillet with the sauce and cook for 3-4 minutes more.
Add the oil to the pan on medium heat. Add the apples, shallots and thyme to the pan and cook for 2 minutes. Add the apple cider and broth and bring to a simmer. Cook for 3 minutes.
Return the chicken and juices to the skillet and reduce to low. Simmer for 4 minutes. Add in the sour cream and parsley and serve.
Notes
If you can’t find fresh cider, substitute unsweetened, unfiltered apple juice.
