Before you start

Before you begin, ensure you have all your ingredients measured and ready to go. Thaw the frozen tots slightly if they are clumped together in the bag, and ensure the chicken is cut into uniform, bite-sized cubes for even cooking.

Preheat your oven fully to 400°F (200°C) before you start layering the dish to ensure the cooking process begins immediately upon placing the dish in the oven.

Ingredients at a glance (4)
  • 2 lbs chicken breast, cut into bite-size cubes
  • 1 1/2 cups creamy buffalo sauce
  • 32 oz frozen potato tots
  • 2 cups shredded mozzarella cheese

Instructions

Layering the foundation

  1. Assemble the base
    Preheat the oven to 400°F (200°C). Arrange the raw chicken breast cubes in an even layer across the bottom of a large ceramic baking dish. Ensure the pieces are spread out to promote even cooking throughout the base of the casserole.
    Look for The chicken pieces should cover the bottom of the dish completely.
    Tip Pat the chicken dry with paper towels before placing it in the dish to prevent excess moisture from watering down the sauce.

At the end of this phase, the baking dish should be neatly lined with an even layer of raw chicken cubes. This provides the necessary base for the rest of the ingredients to sit on, ensuring that the chicken cooks in the moisture released by the sauce and the heat of the oven, preventing it from drying out during the baking process.

Adding sauce and topping

  1. Add sauce and topping
    Pour the creamy buffalo sauce evenly over the cubed chicken, ensuring every piece is coated. In a separate bowl, toss the frozen potato tots with the shredded mozzarella cheese. Scatter the cheesy tot mixture over the top of the sauced chicken in an even layer.
    Look for The tots should create a uniform top layer covering the chicken completely.
    Tip Mixing the cheese with the tots first helps ensure an even distribution of melted cheese throughout the crispy topping.

The casserole should now be fully assembled with a layer of creamy buffalo sauce covering the chicken and a blanket of cheesy tots on top.

The ingredients should be distributed evenly to ensure that every serving contains a balance of chicken, sauce, and crispy potatoes, creating a consistent experience throughout the entire dish once it finishes baking.

Baking the casserole

  1. Bake and serve
    Transfer the baking dish to the preheated oven and bake until the tots are golden brown and the edges are bubbling. Check that the chicken has reached an internal temperature of 165°F (74°C). Remove from the oven and let rest for five minutes before serving to allow the sauce to set.
    Look for Look for deep golden brown tots and a bubbling, thick sauce around the edges of the dish.
    Safe temperature 165°F (74°C) internal temperature (poultry)
    Tip Use a meat thermometer inserted into the center to confirm the chicken is fully cooked through.

Once the timer goes off, the casserole will look golden and crispy on top, with a bubbling, fragrant sauce visible around the sides. The cheese should be melted throughout the tot layer, binding everything together into a cohesive, comforting dish that is ready to be served after a brief rest to allow the sauce to thicken.

Common mistakes

Avoid overcrowding the baking dish, as this prevents the chicken from cooking evenly and keeps the sauce from thickening properly.

Another common mistake is failing to toss the tots with the cheese, which leaves the potatoes dry and the cheese clumped in one area. Finally, do not skip the resting time, as the sauce needs a few minutes to settle into a rich, creamy consistency before serving.

How to tell it’s done

The casserole is done when the potato tots are golden brown and crispy and the sauce is bubbling intensely around the edges.

Most importantly, use a digital meat thermometer to ensure the chicken breast has reached an internal temperature of 165°F (74°C). The cheese should be melted and lightly browned in spots, indicating the dish is ready to be pulled from the oven.

  • Poultry: 165°F (74°C) in the thickest part
