Ingredients
- 2–3 large boneless, skinless chicken breasts
- ½ large red onion, sliced into half-moon rounds
- 1 tablespoon olive oil
- 1 packet ranch seasoning
- ½–¾ cup barbecue sauce
- 3–4 sliced pepperoncini per piece of chicken
- 1 teaspoon pepperoncini juice
- 2 cups freshly shredded mozzarella cheese
- 1½ cups French fried onions
- 4 tablespoons salted butter, melted
Instructions
- Preheat the oven to 350°F (175°C).
- Butterfly the chicken breasts all the way through so you have 4–6 thinner chicken pieces.
- Spread the sliced red onion across the bottom of a 9×13-inch baking dish. Drizzle with olive oil and sprinkle with about one-quarter of the ranch seasoning. Toss to coat, then arrange the onions in an even layer.
- Place the chicken pieces in a single layer over the onions. Sprinkle the remaining ranch seasoning evenly over the chicken.
- Spoon the barbecue sauce over the chicken, using approximately ¼ cup per whole chicken breast and dividing it between the butterflied pieces.
- Arrange 3–4 pepperoncini slices over each chicken piece. Drizzle 1 teaspoon of pepperoncini juice across the entire baking dish.
- Sprinkle the freshly shredded mozzarella evenly over the chicken.
- Place the French fried onions in a large zip-top bag and gently crush them into rustic pieces. Add the melted butter, seal the bag, and shake until the onions are evenly coated.
- Sprinkle the buttery fried onions evenly over the mozzarella.
- Cover the baking dish tightly with aluminum foil, crimping the foil securely around the edges. This traps moisture inside and helps keep the chicken tender while it cooks.
- Bake the Mississippi Mud Chicken Bake covered for 25 minutes.
- Carefully remove the foil and bake uncovered for another 10–15 minutes, until the cheese is bubbling, the onion topping is golden, and the chicken is completely cooked.
- Check the thickest portion of the chicken with an instant-read thermometer. It should reach 165°F (74°C).
- Rest for about 5 minutes before serving.
Tips & Tricks
For evenly cooked chicken, butterfly the breasts into pieces of similar thickness. Very thick pieces can take considerably longer to reach a safe internal temperature.
Freshly shredded mozzarella is ideal because it generally melts more smoothly than packaged pre-shredded cheese.
Choose a barbecue sauce your family already enjoys. A smoky sauce creates a deeper barbecue flavor, while a sweeter variety makes the finished ranch chicken casserole milder and more family-friendly.
Don’t finely pulverize the French fried onions. Leaving some larger pieces creates a much better crunchy topping.
The pepperoncini add tang rather than overwhelming heat. For an even milder dish, reduce the pepperoncini and omit the extra juice.
Use halal-certified ranch seasoning, barbecue sauce, cheese, and French fried onions when needed to ensure all packaged ingredients meet your dietary requirements.

Notes
You can substitute another good melting cheese for some or all of the mozzarella. Monterey Jack, cheddar, or a combination of cheeses can give this barbecue chicken bake a slightly different flavor.
Serve it with mashed potatoes, rice, roasted potatoes, or crusty bread to soak up the flavorful juices. For something lighter, pair the chicken with steamed green beans, broccoli, roasted vegetables, or a simple green salad.
If your chicken pieces are particularly thick, they may need additional baking time. Always use an internal temperature of 165°F (74°C), rather than cooking time alone, to determine when chicken is done.

FAQ
What is Mississippi Mud Chicken Bake?
Mississippi Mud Chicken Bake is a comforting baked chicken dish layered with ranch seasoning, barbecue sauce, pepperoncini, mozzarella, and crunchy buttery fried onions. This version combines tangy, smoky, cheesy, and savory flavors in one casserole-style dinner.
Can I make this cheesy chicken casserole ahead of time?
Yes. You can assemble the chicken, onions, seasoning, barbecue sauce, pepperoncini, and mozzarella ahead of time and refrigerate them in a covered baking dish. For the best texture, prepare and add the French fried onion topping shortly before baking.
Is Mississippi Mud Chicken Bake spicy?
It has a tangy kick from the pepperoncini, but it does not have to be particularly spicy. You can use fewer pepperoncini slices and skip the additional pepperoncini juice for a milder version.
How do I know when the chicken is fully cooked?
Insert an instant-read thermometer into the thickest part of the chicken. Poultry should reach a safe internal temperature of 165°F (74°C). Avoid relying solely on the color of the meat or juices.
What can I serve with Mississippi chicken bake?
Mashed potatoes, white rice, roasted potatoes, green beans, broccoli, corn, or a crisp green salad all work well. Potatoes and rice are especially good for enjoying the cheesy barbecue-flavored juices from the baking dish.
Can I use chicken thighs instead of chicken breasts?
Boneless, skinless chicken thighs can work, although the cooking time may change depending on their size and thickness. Cook them until they reach a safe internal temperature of at least 165°F (74°C).
Storage
Allow leftovers to cool before transferring them to an airtight container. Refrigerate promptly and keep for up to 3–4 days.
For longer storage, freeze individual portions in freezer-safe containers. Keep in mind that the French fried onion topping will lose some of its original crispness after freezing and thawing.
Reheat refrigerated portions in a covered baking dish at 350°F until thoroughly heated. Remove the cover toward the end to help crisp the topping again. Individual portions can also be reheated in the microwave, although the topping will be softer.
