Begin by placing your slow cooker on a stable surface and set it to the low setting. Take four large chicken breasts and arrange them in an even layer at the bottom of the slow cooker.

Next, take the 12 pepperoncini peppers and scatter them around the chicken breasts. Pour in 1/4 cup of juice from the pepperoncini jar.

Sprinkle the 1-ounce packet of ranch seasoning mix evenly over the chicken breasts. Follow this by adding the 1-ounce packet of au jus gravy mix.

Now, take 1/2 cup of unsalted butter, cut into pieces, and place it on top of the chicken and seasonings.

Cover the slow cooker with its lid and set it to cook on high for 3-4 hours or low for 6-8 hours.

Once the chicken is cooked, use two forks to shred the meat right in the slow cooker.
