Momidaze – Here is the recipe I use for Tater Tot Casserole.  

TATER TOT CASSEROLE

2-1/2 cups ground beef, Cooked
small onions, chopped
1 – 10 oz cream of mushroom soup
3/4 Cups Milk
1 Can Green Beans (15 oz)
1 Can Corn (15 oz)
8 oz.  Cheddar Cheese, Shredded
32 ounces Tater Tots

In a skillet, fry onions until tender.  Mix together hamburger, onions, soup, milk green beans and corn.  Pour into a 9x 13 cake pan.  Sprinkle with cheese and top with Tater tots.     Bake at 350 degrees for 1 hour.    I do make this and bag up and freeze the mixture and then later will put it in a pan and add the Tater Tots and Cheese when I thaw it and make it.
