Slow Cooker Mississippi Chicken is a spin-off of the Slow Cooker Mississippi Pot Roast that my family loves. This chicken is so easy to make, another dump-and-go recipe. It is Keto friendly and takes less than 5 minutes of prep time.
Simply place some chicken in the slow cooker. As usual, I use Reynolds Slow Cooker Liners for extremely easy cleanup. Sprinkle on a packet of dry ranch seasoning mix, and top with sliced pepperoncini or banana peppers and butter.
You can use any form of chicken that you prefer. Chicken thighs or bone-in split chicken breasts, chicken drumsticks, boneless chicken breasts, or tenderloins all work well. Chicken thighs can be a very affordable option. When using chicken thighs, cut the butter in half, as they are pretty greasy.

I like using frozen chicken breasts. They are more affordable than fresh chicken breasts, and they hold up well to the longer cooking time. Plus, I have a 40-pound box in the freezer that I scored for 99¢ a pound. According to Crockpot.com safety guidelines, “You can cook frozen meat in a Crock-Pot® Slow Cooker, but suggested cook time may need to be increased”.
When the chicken is ready and has reached an internal temperature of 165ºF. You can take a couple of forks and shred the chicken if you wish. It will be very tender. Serve hot!

Enjoy as a low-carb (Keto) meal on cauliflower rice or zoodles. Or serve on rice, mashed potatoes, tortilla shells, or on a toasty bun with cheese. I made sure I’d have leftovers, so I could use them in quesadillas later this week.
