How to Make Oven Baked Mississippi Chicken Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 400 degrees Fahrenheit, which is just right for a quick bake that keeps the chicken juicy inside. Lightly grease an 11×7-inch baking dish or a similar-sized one to prevent sticking and ease cleanup later.
Step 2: Prep the Chicken Breasts
Pat your chicken breasts dry with paper towels. This little step helps the seasoning stick better and ensures a nice texture. Lay the chicken breasts evenly across the bottom of your prepared baking dish, setting the stage for all those flavorful toppings.
Step 3: Season the Chicken
Sprinkle the ranch seasoning and au jus gravy mix evenly over the chicken breasts. These two seasonings work hand in hand to create that classic Mississippi flavor, infusing each bite with savory, herby goodness.
Step 4: Add Butter and Pepperoncini
Distribute the butter slices over the seasoned chicken, then layer on the pepperoncini peppers. Pour in the pepperoncini juice too—it may seem like a small detail, but it adds a bright, zesty contrast that elevates the entire dish.
Step 5: Bake Until Perfect
Place your dish in the preheated oven and bake uncovered for 30 to 35 minutes. The chicken is done when its internal temperature reaches 165 degrees Fahrenheit. During this time, the butter will melt, mixing with the seasonings and juices to create a mouthwatering sauce.
Step 6: Garnish and Serve
If you’re using fresh parsley, sprinkle it over the chicken just before serving to add a burst of freshness and a lovely visual touch. Now your Oven Baked Mississippi Chicken Recipe is ready to wow your taste buds!
How to Serve Oven Baked Mississippi Chicken Recipe

Garnishes
Fresh chopped parsley is a simple yet beautiful garnish that adds a hint of herbal aroma and a splash of green to brighten the plate. You could also sprinkle a little freshly cracked black pepper if you like an extra kick.
Side Dishes
This chicken pairs wonderfully with creamy mashed potatoes or steamed rice, which soak up all the buttery, tangy sauce. Roasted vegetables or a crisp green salad also complement the richness, adding balance to your meal.
Creative Ways to Present
For a fun twist, serve this chicken sliced over a bed of buttered noodles or even atop a warm baguette slice for an open-faced sandwich vibe. You could also plate it family-style in the baking dish, letting everyone dig in straight away for a cozy, communal experience.
Make Ahead and Storage
Storing Leftovers
Place any leftover chicken and sauce in an airtight container and refrigerate for up to four days. The flavors will continue to meld, making for an even tastier next-day meal.
Freezing
If you want to save some for later, the baked chicken freezes well. Wrap it tightly or use freezer-safe containers, and it will keep up to three months. Thaw fully in the fridge before reheating for best texture.
Reheating
To keep the chicken moist when reheating, warm it gently in a covered dish in the oven at 325 degrees Fahrenheit or in the microwave with a splash of water or broth to help retain moisture. Avoid overcooking to prevent dryness.
FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Boneless, skinless chicken thighs will work wonderfully and tend to stay even juicier, offering a slightly different texture with the same delicious Mississippi flavors.
What can I substitute for pepperoncini peppers?
If you don’t have pepperoncini on hand, mild banana peppers or even a few mild pickled jalapeño slices can add a similar tangy, slightly spicy kick.
Is this recipe gluten-free?
Check the ranch and au jus gravy mix packets for any gluten-containing ingredients. Many brands offer gluten-free options, making this dish adaptable to gluten sensitivities.
Can I prepare this recipe in a slow cooker instead of the oven?
Yes, you can! Place all ingredients in the slow cooker and cook on low for 4 to 6 hours or on high for 2 to 3 hours, until the chicken reaches the proper internal temperature and is tender.
How can I make this recipe spicier?
Add a bit of cayenne pepper to the seasoning mix or include some spicier pickled peppers alongside the pepperoncini to kick up the heat while keeping all those beloved flavors intact.
