Crockpot Mississippi Chicken Ingredients

You only need a handful of simple ingredients to make this delicious slow cooker Mississippi chicken.

Main ingredients: boneless skinless chicken thighs (or breasts), ranch dressing mix, au jus mix (or brown gravy mix), yellow onion, garlic, pepperoncini peppers and their juice, and unsalted butter.

Chicken: Boneless skinless chicken thighs work best because they remain moist and tender during slow cooking. You may substitute boneless skinless chicken breasts, but they typically cook more quickly—check for doneness earlier to avoid drying out.

Pepperoncini Peppers: Pepperoncinis provide the signature tang and slight bite of Mississippi-style chicken. They are mild in heat; if you prefer, use mild banana peppers instead. Be sure to include some of the pepperoncini juice—it’s an important part of the sauce.

Variations & Substitutions

• Chicken Breasts: Swap thighs for boneless skinless breasts. Reduce cooking time and remove when they reach 165°F to prevent drying.
• Brown Gravy Mix: A 1-ounce packet of brown gravy mix can replace au jus mix if preferred.
• Banana Peppers: Use mild banana peppers for a gentler pepper flavor.
• More Peppers: Add extra pepperoncini if you want a stronger tang.
• Less Butter: Reduce butter if desired; half the amount still yields a tasty result while cutting richness.

How to Make Crockpot Mississippi Chicken

This straightforward recipe takes minutes to prep and then slow-cooks to perfection—ideal for busy days when you want a hands-off dinner.

• Place the chicken in the slow cooker in a single layer if possible.
• Sprinkle the ranch dressing mix and au jus mix evenly over the chicken.
• Add the sliced onion, minced garlic, pepperoncini peppers, and a portion of the pepperoncini juice to the cooker.
• Slice the butter and arrange it across the top of the chicken.
• Cover and cook on Low for 4–6 hours or High for 3–4 hours, until the chicken is tender and reaches an internal temperature of at least 165°F.
• Remove the chicken and shred it with two forks, then stir the shredded meat back into the cooking liquid so it absorbs the sauce before serving.

For chicken breasts: they tend to cook faster than thighs. Cook on Low for about 3–4 hours or on High for 1½–3 hours, checking early and removing the breasts once they reach 165°F to keep them moist.

What to Serve with Mississippi Chicken

This shredded chicken is versatile and pairs well with many sides:

• Mashed potatoes
• White or brown rice
• Egg noodles
• Sandwich rolls or slider buns
• Roasted or steamed vegetables
• A simple green salad

For sandwiches, spoon a little of the cooking liquid over the shredded chicken before tucking it into the roll. You can also serve it French-dip style, with extra juices on the side for dipping.

Storage & Reheating

• Refrigerator: Store leftovers with some cooking liquid in an airtight container for up to 4 days.
• Reheating: Warm gently in the microwave or on the stovetop over medium-low heat; add a spoonful of reserved cooking liquid to keep the meat moist.
• Freezing: Freeze shredded chicken in an airtight, freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating.
