This Creamy Chicken Alfredo Casserole with Bacon is the ultimate comfort food made for busy weeknights. Featuring juicy shredded chicken, crispy tater tots, smoky bacon, and rich Alfredo sauce, it bakes to golden perfection in under an hour. Easy to prepare, kid-friendly, and loaded with flavor, it’s perfect for feeding a family or prepping ahead for freezer meals.
Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine Alfredo sauce, sour cream, garlic powder, onion powder, salt, and black pepper. Mix until smooth.
Add the cooked chicken and 1 cup of mozzarella cheese to the sauce mixture. Stir until everything is well coated.
Spread the mixture evenly in a greased 9×13-inch baking dish.
Arrange the tater tots in a single layer over the top of the chicken mixture.
Sprinkle the remaining ½ cup mozzarella cheese and the Parmesan cheese evenly over the tater tots.
Bake uncovered for 40–45 minutes, or until the tater tots are golden and the casserole is bubbly.
Remove from oven and let cool for a few minutes. Garnish with chopped parsley if desired before serving.
Use rotisserie chicken for extra convenience and flavor.
Crisp the bacon before mixing it into the base for best texture.
Want it lighter? Use light sour cream and reduced-fat cheese.
Spice lovers can add red pepper flakes or hot sauce.
Add frozen vegetables like peas or spinach for extra nutrition without extra prep.
Double the recipe and freeze one for later—it bakes beautifully from frozen.
