Preheat your oven to 190°C. Lightly grease a 23x33 cm baking dish.

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute to form a roux. Gradually pour in the milk, whisking constantly until the sauce is smooth and thick enough to coat the back of a spoon, which typically takes 5-7 minutes. Remove from heat and stir in the ranch dressing, salt, and pepper.

In a large mixing bowl, combine the shredded chicken, chopped bacon, and 120g of the shredded cheddar cheese. Pour the warm ranch sauce over this mixture and stir until all components are evenly coated.

Arrange the frozen potato tots in a single, even layer to completely cover the bottom of the prepared baking dish.

Spoon the chicken and bacon mixture evenly over the potato tots, gently spreading it. Sprinkle the remaining 120g of shredded cheddar cheese over the top.

Bake for 30-35 minutes, or until the cheese is thoroughly melted and bubbly, and the topping is golden brown. Allow the casserole to rest for 5-10 minutes before serving to ensure clean, structured slices.
