This crockpot Mississippi chicken transforms ordinary chicken breasts into a tender, flavor-packed meal that will have everyone asking for seconds. The combination of tangy pepperoncini peppers with rich butter and savory seasonings creates a dish that's simultaneously simple and sophisticated.
I first made this recipe when I needed something foolproof for a dinner party. My guests were so impressed they thought I'd spent hours in the kitchen, but the slow cooker had done all the work while I prepared for their arrival.
Ingredients
- Boneless skinless chicken breasts: Form the protein foundation of this dish. Choose high-quality, evenly sized pieces for consistent cooking.
- Ranch seasoning mix: Provides a perfect blend of herbs and spices that infuses the chicken with savory flavor throughout the cooking process.
- Au Jus gravy mix: Creates the signature Mississippi sauce consistency and adds rich depth without requiring homemade stock.
- Unsalted butter: Half cup seems indulgent but creates the luxurious sauce that makes this dish special. The slow melting process allows it to blend perfectly with the seasonings.
- Pepperoncini peppers: Deliver mild tanginess and subtle heat that balances the richness of the butter. They become incredibly soft during cooking.
- Salt and pepper: For adjusting the final seasoning to your preference.
Step-by-Step Instructions
- Arrange Chicken:
- Place the chicken breasts in a single layer at the bottom of your crockpot. Try to avoid overlapping too much to ensure even cooking throughout all pieces.
- Add Flavor Packets:
- Sprinkle both the ranch seasoning mix and au jus gravy mix evenly over the chicken breasts. Make sure to distribute the seasonings across all pieces for consistent flavor development.
- Top With Butter And Peppers:
- Cut the butter into slices and arrange them across the top of the seasoned chicken. This allows the butter to melt slowly and evenly as it cooks. Place the pepperoncini peppers around the chicken, distributing them throughout the crockpot.
- Set And Forget:
- Cover your crockpot with the lid and set to low for 6-8 hours or high for 4 hours. The longer, slower cooking method yields the most tender results, so opt for that if your schedule allows.
- Prepare For Serving:
- Once cooking is complete, the chicken should be fork-tender. Use two forks to gently pull and shred the chicken while it remains in the crockpot. Stir everything together so the shredded chicken absorbs all the flavorful sauce.

My favorite part of this recipe is the pepperoncini peppers. My grandmother always kept a jar in her refrigerator, and using them in this dish brings back wonderful memories of her kitchen. The first time my daughter tried this recipe, she picked out all the peppers to eat first, just like I used to do as a child.
Make-Ahead Options
The Mississippi chicken mixture keeps wonderfully in the refrigerator for up to 4 days. I often prepare a large batch specifically for planned leftovers. The flavor actually deepens overnight as the ingredients continue to meld together. To reheat, simply warm gently in a skillet with a splash of chicken broth to maintain moisture, or microwave individual portions covered with a damp paper towel.
Serving Suggestions
Mashed potatoes make the perfect base for this saucy chicken, allowing the rich juices to be fully enjoyed. For a lighter option, cauliflower mash works beautifully. The tender shredded chicken also makes incredible sandwiches on buttered rolls with a slice of provolone cheese. For a complete meal, add a simple green vegetable like steamed broccoli or a crisp salad to balance the richness of the dish.
Customize Your Mississippi Chicken
While the classic recipe is perfect as is, there are several ways to make this dish your own. Adding sliced onions to the bottom of the crockpot creates additional sweetness and depth. For heat lovers, include a few dashes of hot sauce or red pepper flakes with the seasoning mixes. If you prefer a creamier finish, stir in 4 ounces of cream cheese during the final 30 minutes of cooking time for a richer, more indulgent sauce.
