Oven-Baked Option

If you don’t have a slow cooker, assemble the chicken with seasonings, butter, and pepperoncini in a 9×13-inch baking dish. Cover tightly with foil and bake at 375°F for 40–45 minutes, or until the chicken is cooked through and easily shredded. Shred and mix with the pan juices before serving.

Frequently Asked Questions

1. Can I use chicken breasts instead of thighs?

Yes. Breasts work well, though they can be slightly leaner. If using the HIGH slow-cooker setting or the oven, watch cooking time to avoid drying out the meat.

2. Do I need to brown the chicken first?

No. This recipe is designed as a dump-and-go slow-cooker meal—no searing required.

3. Can I make this ahead of time?

Definitely. Both the chicken and mashed sweet potatoes store well. Keep them in separate airtight containers in the refrigerator for up to 4 days and reheat gently.

4. Is this a spicy recipe?

Not by default. Pepperoncini contribute tang more than heat. Increase spice by adding extra peppers or a splash of their brine.

5. Can I freeze Mississippi chicken?

Yes. Cool the shredded chicken and its juices, then freeze in a freezer-safe container for up to 3 months. Thaw overnight in the fridge before reheating.
