Oven Mississippi Chicken
Oven Mississippi Chicken is an easy weeknight dinner made with chicken breasts, ranch seasoning, au jus gravy mix, butter, and pepperoncini or banana peppers. It has all the classic Mississippi Chicken flavors you love in a quicker oven-baked version of the crockpot favorite!

Y’all love Mississippi Chicken in the crockpot, but this oven version gives you those same great flavors in less time! With just a handful of ingredients and minimal prep, this Oven Mississippi Chicken is an easy dinner to add to your weekly meal rotation.
The chicken bakes in a buttery combination of ranch seasoning, au jus gravy mix, and tangy peppers, creating plenty of flavor without a lot of work. I like to serve mine over quick microwave rice with a side of green beans for a simple meal that comes together easily on a busy weeknight.
If you love Mississippi Chicken but don't have hours to wait on the slow cooker, this oven-baked version is a great alternative!

💡 Tips for Success
- Choose evenly sized chicken breasts: Chicken breasts that are similar in size will cook more evenly. If some are much larger than others, they may need extra time in the oven.
- Adjust the peppers to your taste: Pepperoncini give this dish its classic Mississippi Chicken flavor, while banana peppers are another great option. Add a few slices or pile them on!
- Don't skip the butter: The butter melts with the seasoning and chicken juices to create a flavorful sauce to spoon over the chicken and rice.
- Check the internal temperature: Cooking time will depend on the thickness of your chicken breasts. Use a meat thermometer to make sure the chicken reaches 165°F.
- Make it a complete meal: Serve with microwave rice and green beans for an easy weeknight dinner. Mashed potatoes or roasted vegetables would also be delicious.
❓ Frequently Asked Questions
Can I use chicken thighs instead of chicken breasts?
Yes! Boneless, skinless chicken thighs can be used in place of chicken breasts. Cooking time may vary, so check that the chicken reaches an internal temperature of 165°F.
Can I use banana peppers instead of pepperoncini?
Absolutely! Both work well in this recipe. Use whichever you prefer, and adjust the amount to your taste.
How do I know when the chicken is done?
The chicken is done when a meat thermometer inserted into the thickest part reads 165°F. The recommended 25–30 minutes is a guideline, since the size and thickness of the chicken breasts can affect cooking time.
What should I serve with Oven Mississippi Chicken?
I love serving it over quick microwave rice with green beans. Mashed potatoes, roasted vegetables, or your favorite side dishes are also great options.
How do I store leftovers?
Store leftover chicken and pan juices in an airtight container in the refrigerator for 3–4 days. Reheat until the chicken reaches 165°F, adding a little broth or water if needed to keep it moist.
Can I make this recipe ahead of time?
You can assemble the chicken with the seasonings, peppers, and butter ahead of time and refrigerate it until you're ready to bake. Keep it refrigerated and bake promptly, allowing for a little extra cooking time if the dish is still cold.
