Preheat oven to 175°C and grease a 23x33 cm baking dish with butter or cooking spray to prevent sticking.

Peel cooled baked potatoes and cut into uniform 2.5 cm cubes to ensure even texture after baking.

Evenly spread half of the cubed potatoes across the bottom of the prepared baking dish to form the foundation.
04 -
Distribute one cup of the shredded rotisserie chicken evenly over the potato layer for balanced flavor and texture.

Whisk together full-fat sour cream and whole milk until smooth to create a rich, creamy binder for the layers.

Sprinkle half of the shredded cheddar cheese, chopped green onions, and bacon bits evenly over the creamy layer.
