Step 1

Preheat oven to 425°F with racks in middle and upper positions. Toss together potatoes, olive oil, and 1 tablespoon of the Creole seasoning in a 13- x 9-inch baking dish. Bake in preheated oven until potatoes are tender (easily pierced with a knife), 30 to 35 minutes, stirring halfway through.

Step 2

Meanwhile, stir together chicken, yogurt, salt, and remaining 1 tablespoon Creole seasoning in a large bowl to combine. Chill chicken mixture while potatoes cook.

Step 3

Once potatoes are fully cooked, remove baking dish from oven. Add chicken mixture, bell pepper, and onion to baking dish with potatoes; toss to combine. Return to oven; bake until chicken is cooked through, 30 to 35 minutes. Remove from oven; turn oven to broil.

Step 4

Top potato and chicken mixture evenly with cheese, cooked bacon, and scallions. Return to oven on top; broil until cheese is melted and bubbly, about 2 minutes. Serve with sour cream and hot sauce, if desired.
