This Mississippi Chicken recipe is perfect for busy nights when you want something flavorful and hands-off. The combination of ranch and au jus mixes with pepperoncini and butter creates a tangy, rich sauce that makes the chicken tender and juicy. It’s been a go-to for family dinners and potlucks because it feels like a special treat without a lot of effort.

I first made this during a busy week, and it immediately became a crowd favorite at home. Now I often double the batch for leftovers, which taste even better the next day.

Ingredients

  • Chicken breasts boneless and skinless: For easy shredding and lean protein
  • Medium onion diced: Adds sweetness and depth of flavor as it cooks down
  • Au jus gravy mix: Enhances the savory richness providing a robust base
  • Ranch dressing mix: Brings creamy herb notes that marry well with the other spices
  • Pepperoncini peppers: These give the dish its signature tang and mild heat Choose fresh looking ones with firm flesh
  • Juice from pepperoncini: Provides acidity and moisture which tenderizes the chicken while flavoring the sauce
  • Butter sliced: Adds luscious richness and helps create a velvety sauce

Instructions

Place the diced onion in the bottom of the crock pot This will create a bed that flavors the chicken gently as it cooks
Arrange the Chicken:

Add Butter Slices:
Dot the top with half a cup of butter sliced into pads This gives the sauce a creamy richness
Pour Pepperoncini Juice:
Pour three quarters of a cup of the pepperoncini juice over everything This moisture helps the chicken cook tender and absorb those tangy notes
Cook the Chicken:
Cover the crock pot and cook on high for 4 to 5 hours or low for 6 to 7 hours Patience here is key for tender juicy meat
