Crockpot Mississippi Chicken Ingredients
Chicken Breasts or Thighs
Both work. Thighs stay extra juicy, breasts shred beautifully.
Ranch Seasoning and Au Jus
Half a packet of ranch and a packet of low sodium au jus build that classic Mississippi flavor without making it too salty.
Pepperoncini Peppers
They add tang and a mild kick. A splash of the brine brightens everything.
Onion and Olive Oil
The sliced onion makes a flavorful bed for the chicken and melts into the sauce.
Good to Know: Check your ranch and au jus packets if you need this to be gluten-free, since some brands contain wheat.
How to Make Crockpot Mississippi Chicken
Step 1: Prep the Crockpot
Lightly spray your crockpot with oil. Slice the onion and spread it across the bottom.
Step 2: Add the Chicken and Seasoning
Lay the chicken on top of the onions. Sprinkle the ranch seasoning and au jus evenly over the chicken, then drizzle with olive oil.
Step 3: Add the Pepperoncini
Add the pepperoncinis along with a splash of the brine.
Step 4: Slow Cook
Cover and cook on low for 6 hours or high for 3 to 4 hours, until the chicken is fall-apart tender. Shred and stir it into the juices.
Carly’s Expert Tips
- Don’t add extra liquid. The chicken and onions release plenty of juice.
- Use low sodium au jus. It keeps the dish from getting too salty.
- Shred in the pot. Let the shredded chicken soak up the juices for 10 minutes before serving.
- Adjust the heat. Add more pepperoncinis for more kick, or fewer for a milder dish.
Make It Your Own
- Creamy: Stir in a few ounces of cream cheese at the end.
- Buttery: Swap the olive oil for a few pats of butter for the classic Mississippi style.
- Spicy: Add a pinch of red pepper flakes or a sliced jalapeño.
- Instant Pot: Cook on high pressure for 12 to 15 minutes with a natural release.
Make-Ahead and Meal Prep: This dish tastes even better the next day as the flavors meld. Shred, portion with the juices, and refrigerate for easy lunches all week.

Storing and Reheating
Fridge: Store in an airtight container with the juices for up to 4 days.
Freezer: Freeze for up to 3 months. Thaw overnight in the fridge.
