02 - Top with butter slices, scatter pepperoncini peppers throughout, pour in pepperoncini juice, and season with black pepper.
03 - Cover and cook on low for 6–7 hours until chicken is tender and easily shredded with forks.
04 - About 30 minutes before chicken finishes, place potatoes and garlic in a large pot, cover with cold water, add salt, bring to boil, then simmer 15–20 minutes until fork-tender.
05 - Drain potatoes and garlic well, return to pot, add butter, milk, and sour cream, then mash until smooth and creamy, adding more milk if needed. Season with salt and pepper.

07 - Spoon mashed potatoes onto plates and top generously with shredded Mississippi chicken and sauce. Garnish with fresh parsley if desired.

# Expert Advice:

01 -
  • The slow cooker does almost all the work while you handle other tasks, and six hours later you come home to shredded, fall-apart chicken that tastes like it simmered all day.
  • Pepperoncini juice transforms ordinary chicken into something tangy and sophisticated, while butter keeps it luxuriously tender.
  • Garlic mashed potatoes soak up every bit of that savory sauce, making this dish feel both elegant and deeply comforting.
02 -
  • Don't skip the pepperoncini juice; it's the secret ingredient that transforms seasoning packets into something genuinely complex and crave-worthy, and you'll notice immediately when it's missing.
  • Drain your potatoes thoroughly and let them steam-dry for a minute in the hot pot before mashing—wet potatoes lead to gluey disappointment, no matter how much butter you add.
03 -
  • If your slow cooker runs hot, start checking the chicken at five and a half hours—overcooked chicken gets stringy in a way that's less appetizing, so tender and shreddable is the goal.
  • Reserve some of the cooking liquid before you shred the chicken; you can drizzle it over the plated dish if the sauce seems too thick or if you just want more of that tangy richness on your potatoes.
