Preheat the Oven: Start by preheating your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.
Prepare the Ranch Mixture: In a large bowl, combine the cream of chicken soup, sour cream, and ranch dressing mix. Stir until well blended.
Add Chicken and Bacon: Fold in the shredded chicken, crumbled bacon (reserve a handful for topping), and 1 cup of the shredded cheddar cheese. Mix everything until the ingredients are evenly coated with the creamy ranch mixture.
Layer the Casserole: Spread the chicken and bacon mixture evenly in the bottom of the prepared baking dish.
Add the Tater Tots: Arrange the tater tots in a single layer over the chicken mixture. For extra crispiness, you can press them down slightly into the casserole.
Top with Cheese and Bacon: Sprinkle the remaining 1 cup of shredded cheddar cheese over the tater tots. Add the reserved crumbled bacon on top for extra flavor.
Bake the Casserole: Place the casserole in the preheated oven and bake for 35-40 minutes, or until the tater tots are golden brown and the cheese is melted and bubbly.
Garnish and Serve: Remove from the oven and let it cool for a few minutes. If desired, garnish with chopped green onions before serving.
