Tender slow-cooked chicken with ranch and pepperoncini, served over creamy garlic mashed potatoes.

# What you'll need:

→ Mississippi Chicken

01 - 2 lbs boneless, skinless chicken breasts or thighs
02 - 1 oz ranch seasoning mix
03 - 1 oz au jus gravy mix
04 - ½ cup unsalted butter, sliced
05 - 8–10 whole pepperoncini peppers
06 - ¼ cup pepperoncini juice
07 - Freshly ground black pepper to taste

→ Garlic Mashed Potatoes

08 - 2½ lbs Yukon Gold potatoes, peeled and cut into chunks
09 - 4 cloves garlic, peeled and smashed
10 - ½ cup whole milk
11 - ¼ cup unsalted butter
12 - ⅓ cup sour cream
13 - Salt and freshly ground black pepper to taste
14 - Chopped fresh parsley for garnish, optional

# Method:

01 - Place chicken in the bottom of a slow cooker. Sprinkle ranch seasoning and au jus gravy mix evenly over the chicken.
02 - Add butter slices on top, scatter pepperoncini peppers, and pour in pepperoncini juice. Season with black pepper.
03 - Cover and cook on low for 6–7 hours, or until chicken is tender and easily shredded with forks.
04 - Place potatoes and garlic in a large pot, cover with cold water, and add a generous pinch of salt. Bring to a boil, then simmer for 15–20 minutes until potatoes are fork-tender.
05 - Drain well, then return potatoes and garlic to the pot. Add butter, milk, and sour cream. Mash until smooth and creamy, adding more milk as needed. Season with salt and pepper.
06 - Once the chicken is done, shred it directly in the slow cooker using two forks, mixing well with the juices.
07 - Spoon mashed potatoes onto plates and top generously with shredded Mississippi chicken and sauce. Garnish with fresh parsley if desired.

# Expert Advice:

01 -
  • Minimal hands-on time: Twenty minutes of prep and then the slow cooker does the heavy lifting while you live your life.
  • Naturally tangy and rich: The pepperoncini juice and butter create a sauce that tastes like it simmered for days, not hours.
  • Feeds a crowd without stress: Six servings of comfort food that's impossible to mess up.
  • Gluten-free friendly: Just swap in certified packets and you're golden.
02 -
  • Don't skip draining the potatoes: I learned this the hard way—soggy mashed potatoes are nobody's favorite, so let that colander do its job.
  • Taste before serving: The seasoning packets vary by brand, so give the chicken sauce a quick taste and adjust salt or pepperoncini juice if needed.
  • The butter and sour cream make the mash: Skimping here turns potatoes into cardboard; go full-fat and generous.
03 -
  • Don't peek constantly: Every time you lift that lid, you add fifteen minutes to cook time; trust the process and resist the urge.
  • Prep your potatoes while the chicken finishes: This timing trick means everything comes together warm and fresh at the same moment.
  • Save some sauce: Spoon an extra drizzle on top of each plate—it's too good to leave behind.
