In a large bowl or zip-top bag, combine the chicken breasts with the buttermilk and ranch seasoning. Make sure all the chicken is well coated. Cover or seal the bag and let it marinate in the fridge for at least 30 minutes, or ideally overnight for maximum flavor.

When you’re ready to cook, heat a skillet over medium heat . Remove the chicken from the marinade and let the excess drip off. Season both sides with salt and pepper.

Place the chicken breasts into a hot skillet cook each side for about 6–8 minutes until golden brown and fully cooked through.

Let the chicken rest for 5 minutes before slicing. Garnish with freshly chopped parsley and serve.
