How to Make the Recipe

Step 1

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish.

Step 2

In a large mixing bowl, combine the shredded chicken, Alfredo sauce, sour cream, frozen peas, garlic powder, salt, and black pepper. Mix well until evenly coated.

Step 3

Spread the mixture evenly into the prepared baking dish.

Step 4

Arrange the frozen tater tots in a single layer on top of the chicken mixture.

Step 5

Sprinkle the shredded mozzarella cheese evenly over the top.

Step 6

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

Step 7

Let cool for 5–10 minutes before serving to allow the casserole to set.

Tips for Making the Recipe

• Use pre-cooked rotisserie chicken to save time.
• Let the sour cream and Alfredo sauce sit at room temperature for easier mixing.
• Don’t thaw the tater tots—they crisp better straight from the freezer.
• Add cheese halfway through baking if you want a gooey top layer.
• Garnish with chopped parsley or extra pepper for presentation.

How to Serve

Serve warm as a complete meal, or pair it with a simple green salad or steamed vegetables for added freshness. It’s great with garlic bread or rolls for a classic comfort food experience. For a casual get-together or potluck, serve straight from the baking dish.

Make Ahead and Storage

Storing Leftovers

Freezing

Assemble the casserole but don’t bake it. Cover tightly with foil and freeze for up to 2 months. When ready to bake, thaw overnight in the refrigerator and bake as directed.

Reheating

Reheat individual servings in the microwave, or warm the whole casserole in a 350°F oven until heated through and crispy on top.
