Preheat oven to 375°F (190°C) and grease a baking dish with butter or cooking spray.

Greasing the dish prevents sticking and makes cleanup easier.📌

In a large bowl, combine the cooked chicken, sour cream, cream of chicken soup, ranch seasoning, 1/2 tsp black pepper, and half of the shredded cheddar cheese. Mix well until everything is thoroughly combined.

Ensure all ingredients are evenly distributed for consistent flavor in every bite.📌

Spread the chicken mixture evenly into the prepared baking dish.

Use a spatula to create an even layer, which helps with even cooking.📌

Sprinkle the cooked and crumbled turkey bacon over the top of the chicken mixture.

Distribute the turkey bacon uniformly for a crispy texture throughout the casserole.📌

Arrange the frozen tater tots in a single layer over the turkey bacon. You can place them close together but avoid overcrowding.

A single layer ensures the tater tots will crisp up nicely on top.📌

Top the tater tots with the remaining shredded cheddar cheese.

The cheese will melt and become golden, adding a delicious crust to the casserole.📌

Bake uncovered for 40–45 minutes, or until the casserole is bubbly and the tater tots are golden brown and crispy.

Keep an eye on the casserole towards the end of baking to prevent over-browning of the cheese.📌
