Start by placing the boneless, skinless chicken breasts in the bottom of your crockpot or slow cooker. Make sure they're arranged in a single layer for even cooking.
02 -
Sprinkle the Ranch seasoning mix and Au Jus gravy mix evenly over the chicken breasts. Try to cover all the chicken pieces to ensure even flavor distribution.

Cut the butter into slices or chunks and place them on top of the seasoned chicken. Then arrange the pepperoncini peppers around the chicken and butter. Season with a bit of salt and pepper to taste, though keep in mind the seasoning packets already contain salt.
04 -
Cover the crockpot with its lid and set to cook on low for 6-8 hours or on high for 4 hours. The slower, longer cooking time on low heat usually results in more tender chicken, but either method works well.
05 -
The chicken is ready when it's tender enough to easily shred with a fork. The internal temperature should reach at least 165°F (74°C) to be fully cooked.
06 -
Using two forks, shred the chicken right in the crockpot. This allows the meat to soak up all the flavorful buttery sauce that has developed during cooking. Mix everything together to ensure the shredded chicken is well-coated.

Serve the Mississippi chicken warm, garnished with freshly chopped parsley if desired. It's delicious served over mashed potatoes or rice, or tucked into sandwich buns for a hearty meal.
