Instant Pot Mississippi Chicken is an easy dinner made with boneless chicken, ranch seasoning, au jus mix, butter, pepperoncini, pepperoncini brine, and a little low-sodium chicken broth. Cook it on High Pressure for 15 minutes, allow a 10-minute natural release, then shred the chicken directly in its rich, tangy sauce.
This chicken is tender, savory, buttery, and pleasantly bright from the pepperoncini. Serve it over mashed potatoes, rice, or egg noodles, or pile it onto sandwich rolls for a comforting meal that takes just 5 to 10 minutes of hands-on preparation.

Mississippi Chicken has earned a place in many busy home kitchens because the ingredient list is short but the finished dish tastes layered and comforting. The ranch seasoning brings herbs and gentle tang, while the au jus mix creates a savory gravy-like base around the chicken.
Butter adds richness, and pepperoncini keep the sauce from tasting heavy. Their brine is just as important as the peppers because it gives the chicken its signature sharp, lightly pickled flavor.
The Instant Pot also makes this recipe practical on a weeknight. Once the ingredients are in the pot, the pressure cooker does the work while you prepare a side dish or set the table.

Ingredients You’ll Need
The recipe uses 2 to 3 pounds of boneless, skinless chicken breasts or thighs. This version uses 2.5 pounds, which gives you plenty of chicken for four to six servings without overcrowding a standard electric pressure cooker.
- Chicken: Breasts are lean and easy to shred, while thighs stay especially moist and tender under pressure.
- Ranch seasoning: One 1-ounce packet supplies the familiar herb-and-spice flavor.
- Au jus seasoning: One 1-ounce packet provides a deep beefy, savory note that pairs well with chicken.
- Butter: Use 1/2 cup unsalted butter, cut into several pieces so it melts evenly over the chicken.
- Pepperoncini: Ten whole peppers add a mild chile bite and a lightly pickled taste.
- Pepperoncini brine: The 1/2 cup of brine gives the sauce its tang and contributes necessary cooking liquid.
- Chicken broth: Use 1/2 cup low-sodium broth to help the Instant Pot reach pressure without making the finished sauce too thin.
Because ranch mix, au jus mix, and pepperoncini brine can all be salty, low-sodium broth and unsalted butter are the best choices. There is usually no need to add extra salt before tasting the cooked sauce.

How to Make It Step-by-Step
Step 1: Trim any visible excess fat from the chicken and check the pieces for very uneven thickness. Place the chicken in the Instant Pot in a mostly even layer, using thighs or pounding especially thick breasts to a more consistent thickness when needed.
Step 2: Pour the 1/2 cup pepperoncini brine and 1/2 cup low-sodium chicken broth around the chicken. Do not skip this liquid because an electric pressure cooker needs enough thin liquid to build pressure properly.
Step 3: Sprinkle the ranch dressing seasoning and au jus gravy seasoning evenly over the chicken. Keeping the seasoning distributed across the surface helps every piece absorb the savory herb flavor as it cooks.
Step 4: Cut the 1/2 cup butter into several chunks and place them over the seasoned chicken. Add the whole pepperoncini on top rather than stirring everything aggressively, which keeps the layers simple and lets the butter melt into the cooking liquid.
Step 5: Secure the Instant Pot lid and turn the valve to the sealing position. Select High Pressure for 15 minutes, or choose 18 minutes if the chicken breasts are especially thick.
Step 6: When the cooking time ends, leave the pot undisturbed for a 10-minute natural pressure release. Carefully quick-release the remaining pressure, keeping your face and hands away from the steam, and open the lid after the pressure pin drops.
Step 7: Check the thickest chicken piece with an instant-read thermometer to confirm it has reached at least 165°F. If the chicken is not fully cooked, return it to pressure for a short additional cooking period rather than serving it underdone.
Step 8: Shred the chicken with two forks directly in the pot, or transfer it briefly to a bowl if you prefer more room. Stir the meat back through the buttery pepperoncini sauce and let it rest for 5 minutes so it absorbs more flavor.
Step 9: Spoon the chicken and sauce over mashed potatoes, rice, or egg noodles. You can also serve it on sandwich rolls, with a few extra pepperoncini on top for color and a brighter bite.
Pressure Cooker Tips for Tender Chicken
Chicken breasts vary widely in size, so thickness matters more than the number of pieces. Fifteen minutes on High Pressure works well for standard breasts or smaller pieces, while very thick breasts may need 18 minutes.
Chicken thighs are a forgiving option if you are concerned about dryness. They remain moist under pressure and shred beautifully once they have rested in the sauce.
Do not pour the seasoning packets into a dry pot. The broth and brine are needed for pressure cooking, and the liquid also carries the ranch, au jus, and butter flavors throughout the dish.
For less heat and tang, reduce the number of whole pepperoncini but retain the measured brine. The peppers themselves are mild, but using fewer gives you a softer finished flavor without losing the important pickled note.

What to Serve with Mississippi Chicken
Creamy mashed potatoes are a classic pairing because they catch every drop of the buttery au jus sauce. Rice is another excellent choice, especially if you want a simple side that can be prepared while the chicken cooks.
Egg noodles make the meal feel like a hearty skillet supper, while sandwich rolls turn the shredded chicken into an easy handheld dinner. Add a crisp green salad, steamed green beans, or roasted broccoli to balance the richness.
- Comforting: Mashed potatoes and a simple green vegetable.
- Quick: Microwave rice and bagged salad.
- Family-style: Egg noodles with roasted carrots.
- Casual: Sandwich rolls with crunchy slaw and extra pepperoncini.

Storage, Reheating, and Leftovers
Cool leftover chicken promptly and transfer it with some of the sauce to an airtight container. Refrigerate it for up to 3 days, keeping the meat coated so it does not dry out.
Reheat gently in a saucepan over low to medium heat, stirring occasionally and adding a splash of chicken broth if the sauce has thickened. Individual portions can also be warmed in the microwave in short intervals, covered loosely to retain moisture.
The shredded chicken is useful beyond the first dinner. Use it in wraps, spoon it over baked potatoes, or add it to a salad for a quick lunch.

Common Questions
Can I use frozen chicken? This recipe is written for thawed chicken so the timing and doneness are more predictable. If using frozen pieces, follow your pressure cooker’s safety guidance and check the internal temperature carefully before shredding.
Can I leave out the pepperoncini? You can, but the dish will lose much of its characteristic tang. If you want less pepper flavor, use fewer peppers and keep the brine.
Why is my sauce salty? Ranch mix, au jus mix, and brine all contribute salt. Unsalted butter and low-sodium broth help, and serving the chicken over plain potatoes, rice, or noodles also balances the sauce.
Can I use chicken thighs? Yes. Boneless, skinless thighs are an excellent choice and tend to stay particularly moist during pressure cooking.
