Chicken alfredo tater tot casserole puts an Italian twist on a classic casserole concept. It’s a creamy, delicious dinner that’s easy to make and easy to customize.
Preheat the oven to 375 degrees. Prepare a nine-by-13-inch baking dish by spraying it with cooking spray, and set it aside.
Heat the olive oil in a skillet over medium heat. Add the onion, bell pepper and mushrooms, and saute until everything is cooked through.
Add the chicken, alfredo sauce, and seasonings to a bowl and mix it well. (If your alfredo sauce is already seasoned the way you like, you don’t need to add all the extras. Just follow your heart.)
Evenly spread the chicken mixture into the bottom of your prepared pan.
Cover the top with a single layer of tater tots, and then top evenly with the cheese.
Bake for 25 to 30 minutes or until the cheese is lightly browned on top.
