How Mississippi Chicken Casserole Became This Season’s Viral Comfort Dinner
Precision matters when combining high-sodium spice blends with whole dairy. Follow these steps to assemble the bake without curdling or excessive oil separation.
1. Base Preparation and Seasoning
Preheat the oven to a standard baking dish temperature of 375°F (190°C). Lightly grease a 9x13-inch ceramic or glass casserole pan with unsalted butter. Shred approximately 4 cups of cooked chicken, the breast and thigh meat from a single grocery store rotisserie bird works best. Spread the meat evenly across the floor of the dish.
In a medium bowl, blend 8 ounces of room-temperature softened cream cheese with 1/3 cup of sour cream, 2 tablespoons of pepperoncini brine, half a packet of ranch seasoning, and half a packet of au jus mix. Using a hand mixer or stiff spatula, beat the mixture until smooth. Dollop this seasoned paste over the chicken and gently spread it outward using an offset spatula.
2. The Pepper and Butter Distribution
Arrange 8 to 10 whole pickled pepperoncini peppers across the surface. Leave the stems on if serving to adults who enjoy plucking them whole, or snip the stems and slice the pods into rings for kid-friendly serving.
Cut 4 tablespoons of cold unsalted butter into thin pats and disperse them evenly across the top. The cold butter melts slowly, basting the cream cheese layer as it liquefies and preventing the dairy proteins from scorching before the center warms through.
3. The Melt and Broil Finish
Slide the pan onto the center oven rack and bake uncovered for 20 minutes. Remove the dish and layer 6 to 8 thick slices of provolone across the top, overlapping them slightly to create an unbroken dairy shield.
Return the casserole to the oven for an additional 8 to 10 minutes until the provolone is completely liquefied and bubbling around the perimeter. For crisp, blistered spots, switch the oven to high broil for 90 to 120 seconds. Monitor the broiler constantly; provolone transitions from golden to charred rapidly. Let the casserole rest on a cooling rack for 7 minutes before cutting so the juices can stabilize.
