Equipment

  • Slow Cooker or Instant Pot
  • Measuring cups and spoons
  • Knife
  • Cutting board
  • Two forks (for shredding)
  • Serving spoon

Ingredients
  

  • 2-3 lbs boneless, skinless chicken breasts
  • 1 packet Ranch Dressing Mix
  • 1 packet Au Jus Gravy Mix
  • 4-6 pepperoncini peppers, whole
  • 2 tablespoons pepperoncini juice
  • ¼ teaspoon salt, or to taste
  • ¼ teaspoon black pepper, or to taste

Instructions
 

  • Place the chicken breasts in the slow cooker.
  • Sprinkle the ranch dressing mix and au jus gravy mix evenly over the chicken.
  • Place the butter pats on top of the chicken and mixes.
  • Nestle the pepperoncini peppers among the chicken breasts. Add the pepperoncini juice.
  • Season lightly with salt and pepper.
  • Cover the slow cooker and cook on low for 6-8 hours, or on high for 3-4 hours, until the chicken is very tender and easily shreddable. Alternatively, cook in an Instant Pot on high pressure for 25 minutes, followed by a natural pressure release for 10 minutes.
  • Once the chicken is cooked, use two forks to shred it directly in the slow cooker or Instant Pot.
  • Stir the shredded chicken into the sauce to coat it evenly.
  • Serve immediately over rice, mashed potatoes, or in sandwiches, and enjoy!

Notes

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.
