Notes
Can I Change Up the Recipe?Absolutely. We make Crockpot Mississippi Chicken with chicken breasts, but you can also use boneless, skinless chicken thighs if that’s what you have. They work beautifully in the slow cooker and hold up well during shredding.For the au jus mix, you can swap in a packet of brown gravy mix or beef bouillon powder. Some substitutions can be quite a bit saltier, so keep an eye on that.If you don’t have whole pepperoncini peppers, try banana peppers instead, or use sliced mild pickled chillies for a similar tangy kick. Add a spoonful more of the juice or toss in an extra pepper for a little extra heat.Can I make slow cooker Mississippi Chicken without ranch dressing mix?You can substitute the ranch dressing mix with a homemade blend of dried herbs and spices, such as dill, parsley, garlic powder, and onion powder. This allows you to control the flavor and sodium content to your preference.Is it necessary to use pepperoncini peppers?While pepperoncini peppers contribute to the signature tangy flavor, you can substitute them with banana peppers or omit them for a milder taste. However, this will alter the traditional flavor profile of the dish.Can I prepare Mississippi Chicken in an Instant Pot?Absolutely. To make Instant Pot Mississippi Chicken, combine all ingredients in the pot and cook on high pressure for about 10 minutes, followed by a natural release. This method yields tender, flavorful chicken in a fraction of the time.
