Mississippi Chicken is a flavorful and incredibly easy slow-cooker recipe that combines chicken breasts with ranch dressing mix, au jus gravy mix, butter, and pepperoncini peppers. The result is tender, juicy, and tangy chicken perfect for serving over rice, mashed potatoes, or in sandwiches.
For spicier chicken, add more pepperoncini peppers or a pinch of red pepper flakes. To make it creamier, stir in a dollop of sour cream or cream cheese after shredding. Leftovers can be stored in the refrigerator for up to 3-4 days or frozen for up to 2-3 months. Adjust the amount of pepperoncini peppers based on your spice preference. Be careful not to overcook the chicken; it should be easily shreddable but not dry. If using salted butter, reduce the amount of added salt.
