Preheat your oven to 350°F (175°C) and get it nice and warm.
In a large bowl, combine the cooked chicken, cream of chicken soup, cream cheese, sour cream, half of the cheddar cheese, bacon bits, garlic powder, onion powder, salt, and pepper. Mix everything together until it's smooth and well combined.
Take a greased 9×13-inch baking dish and evenly spread the chicken mixture across the bottom. This is where the magic begins!
Layer the frozen tater tots on top of the chicken mixture, arranging them so every bite gets that perfect crispy texture.
Sprinkle the remaining cheddar cheese over the tater tots for that cheesy, golden topping.
Place the dish in the preheated oven and bake for about 30-35 minutes, or until the tater tots are golden brown and crispy and the casserole is bubbling with goodness.
After baking, let it cool for a few minutes. Garnish with fresh parsley if you’d like, and then serve. Enjoy every cheesy, savory bite!
