Ingredients Equipment Method Notes

Ingredients
  

  • 2 cups Cooked, shredded chicken (Creamy Base)
  • 1 jar (15 oz) Alfredo sauce (jarred) (Creamy Base)
  • 1 cup Sour cream (Creamy Base)
  • 1 cup Frozen peas (Creamy Base)
  • 1 tsp Garlic powder (Seasoning)
  • 0.5 tsp Salt (Seasoning)
  • 0.5 tsp Black pepper (Seasoning)
  • 1 bag (32 oz) Frozen tater tots (Topping)
  • 1 cup Shredded mozzarella cheese (Topping)

Equipment

  • 9 x 13-inch casserole dish
  • large mixing bowl

Method
 

  1. Preheat your oven to $375^{circ}text{F}$ ($190^{circ}text{C}$). Grease a $9 times 13$-inch casserole dish.
  2. In a large mixing bowl, combine the shredded chicken, Alfredo sauce, sour cream, frozen peas, garlic powder, salt, and black pepper. Stir until the mixture is well combined and the chicken is evenly coated in the creamy sauce.
  3. Pour the chicken and Alfredo mixture into the prepared casserole dish, spreading it out evenly to form the base.
  4. Arrange the frozen tater tots in a single layer on top of the casserole mixture. Ensure the entire surface is covered.
  5. Bake the casserole in the preheated oven for about 30 minutes, or until the tater tots are golden brown and crispy.
  6. Remove the casserole from the oven. Sprinkle the shredded mozzarella cheese over the crispy tater tots.
  7. Return the casserole to the oven and bake for an additional 10 minutes, or until the cheese is completely melted and bubbly.
  8. Let the casserole cool for a few minutes before serving.

Notes

Rotisserie chicken is a great shortcut for the shredded chicken. For the best result, ensure the tater tots are arranged in a single layer to crisp up evenly during the initial bake. To make ahead, assemble the casserole (up to adding the tots), cover, and refrigerate for up to 1 day; add 5–10 minutes to the baking time if baking from cold. You can stir in cooked bacon bits or sautéed mushrooms for extra richness.
