This has become a family favorite - I found this recipe on a bag of tater tots several years ago. This is very similiar to a Chicken Pot Pie with a Tater Tot topping instead of bread. It makes a great one dish meal with a salad and bread.
Stir ingredients together and cook over medium heat until hot and bubbly. Stirring occasionally.
Cover and cook an additional 5 minutes; stirring frequently.
Spoon chicken mixture into ungreased 2-quart casserole dish.
Arrange frozen tater tots on top.
Bake 40 minutes or until bubbly and tater tots are slightly browned.
Note: This recipe easily doubles and you can make two. I freeze the extra one with the tater tots on top and then remove and thaw in fridge. Bake as directed above. Also, I sometimes add an extra can of soup and an extra 1/4 cup of milk for a thinner consistency. This would be a personal preference. Also, I add approximately 1/2 tsp of dried thyme and 1/2 tsp of black pepper for one casserole - adaptable to your taste.
