What Is Mississippi Chicken Casserole?
Mississippi Chicken Casserole is a baked comfort food inspired by the famous Mississippi Chicken recipe that became popular throughout the South. While the original version is often slow-cooked with butter, ranch seasoning, au jus gravy mix, and pepperoncini peppers, the casserole transforms those same bold flavors into a creamy pasta bake.
The result is a hearty dinner that’s packed with layers of flavor. Every bite combines juicy shredded chicken, tender pasta, creamy cheese sauce, and just enough tang from the pepperoncini peppers to balance the richness.
Unlike many casseroles that rely heavily on canned soups, Mississippi Chicken Casserole delivers its signature flavor through a combination of seasonings and fresh ingredients, creating a homemade taste that’s difficult to resist.

How to Make Mississippi Chicken Casserole
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Cook the egg noodles until just al dente according to package instructions.
Drain well and set aside.
Avoid overcooking the noodles since they’ll continue cooking in the oven.
Step 2: Make the Creamy Sauce
In a large mixing bowl, combine:
- Softened cream cheese
- Sour cream
- Ranch seasoning
- Au Jus gravy mix
- Garlic powder
- Onion powder
- Black pepper
Mix until completely smooth.
Fold in half of the cheddar cheese and half of the mozzarella cheese.
Step 3: Combine Everything
Add the cooked noodles, shredded chicken, sliced pepperoncini peppers, and melted butter to the creamy mixture.
Stir gently until every piece of pasta and chicken is evenly coated.
Step 4: Assemble the Casserole
Lightly grease a baking dish.
Spread the mixture evenly into the dish.
Top with the remaining cheddar and mozzarella cheeses.
For extra richness, place a few thin slices of butter across the top before baking.
Step 5: Bake
Bake at 350°F (175°C) for about 30 to 35 minutes, or until the casserole is hot, bubbly, and the cheese is beautifully melted.
For a golden top, broil for 2 to 3 minutes at the end.
Step 6: Let It Rest
Allow the casserole to rest for 5 to 10 minutes before serving.
This helps the creamy sauce thicken and makes serving much easier.
Expert Tips for the Best Mississippi Chicken Casserole

Taste Before Adding Salt
