Preheat oven to 375 degrees F. Place oven rack in center of oven. Place 13- x 9-inch baking dish on top of a baking sheet. To serve four people, cut ingredient portions in 1/2 and use a 9- x 9-inch pan for smaller serving size.
In small bowl, mix together beef bouillon granules and boiling hot water until the bouillon is dissolved.
In a large skillet or frying pan over medium heat, brown the ground beef and then drain off the fat and discard. Add in the beef bouillon/water mixture, cream of mushroom soup, cream of celery soup, cream cheese cubes, onion powder, and garlic powder. Stir together until cream cheese is melted and beef mixture is blended. Add salt and pepper to taste (you most likely will not need add additional seasonings since bouillon and cream soups already contain sodium).
Pour beef mixture into the prepared baking dish. Layer green beans evenly over the top of the beef mixture. Next, cover green bean layer with a single layer of frozen tator tots. Sprinkle shredded cheese over the tator tot layer until completely covered.
Place baking sheet with the baking dish in the preheated oven. Bake 45 minutes or until tator tots are browned on top and cooked through.
Serve casserole on individual plates and enjoy.
Makes 6 to 8 servings.
* Can substitute 2 cups of beef stock for beef bouillon and water,
