1. Preheat your oven to 375°F (190°C). While it’s warming up, grease a 9×13-inch baking dish to prevent sticking.
2. In a large bowl, combine the cooked chicken, Alfredo sauce, garlic powder, Italian seasoning, salt, and pepper. Stir in the frozen peas if you’re using them—I find they add a nice pop of color and nutrition.
3. Spread the chicken mixture evenly in the prepared baking dish. Top with an even layer of tater tots. I like to line them up neatly, but if you’re in a rush, just throw them on—no judgment here!
4. Sprinkle the mozzarella and Parmesan cheese over the tater tots. This is where the magic happens as the cheese melts and bubbles, creating a golden crust.
5. Bake in the preheated oven for 30-35 minutes, or until the tater tots are crispy and the cheese is golden brown. Let it cool for a few minutes before serving—if you can resist!

And there you have it, folks! A dinner that’s as delicious as it is easy. I love watching my kids’ faces light up when I pull this casserole from the oven, the cheese stretching as I serve the first piece.
