Step 1: Prepare the Chicken
Start by placing those boneless, skinless chicken breasts right at the bottom of your Crock Pot. This straightforward approach ensures they soak up every bit of flavor from the seasoning and juices as they cook.

FAQs
Can I use chicken thighs instead of breasts?
Absolutely! Chicken thighs work wonderfully in this Crock Pot Mississippi Chicken Recipe, offering even more juiciness and rich flavor. Just adjust cooking time slightly if needed, as thighs can sometimes cook a bit faster.
Are the pepperoncini peppers very spicy?
Pepperoncini peppers are actually quite mild and more tangy than hot. They add a lovely gentle heat and a bright, vinegary kick that complements the creamy sauce perfectly without overwhelming your palate.
Can I make this recipe without butter?
Butter is key for that creamy richness, but if you’re avoiding dairy, you can substitute with a plant-based butter or a drizzle of olive oil. Just keep in mind the flavor and texture will be a little different, but still delicious.
How can I thicken the sauce if it’s too thin?
If after cooking the sauce seems too thin, you can remove the chicken and stir in a slurry of cornstarch and cold water, then cook on high with the lid off for 20-30 minutes until it thickens to your liking.
Is this recipe gluten-free?
Check the labels of your ranch dressing mix and au jus gravy mix, as some brands contain gluten. There are gluten-free versions available widely, so simply choose those to keep this Crock Pot Mississippi Chicken Recipe gluten-free.
