  • 1 pound ground beef
  • Half of a medium yellow onion diced
  • One 10 ounce can Rotel tomatoes not drained
  • One 15.25 ounce can whole kernel corn drained
  • One 10.5 ounce can condensed cream of mushroom soup undiluted
  • 1 ½ cups Colby and Monterey Jack cheese shredded, divided
  • 1 cup sour cream
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon ground black pepper
  • 1 tablespoon chives chopped
  • One 32 ounce bag tater tots


  • Preheat oven to 375°F.
  • Lightly spray the bottom of a 9x13 pan with cooking spray. Place the tater tots in the dish and pre-bake for 8 minutes. Remove from the oven and transfer to a bowl.
  • Turn the oven up to 425°F.
  • In a large skillet cook your onions and ground beef until beef is no longer pink and onions are tender.
  • Pour in the Rotel tomatoes, garlic powder, onion powder and black pepper. Cook until the liquid has reduced, about 8 minutes.
  • Remove from the heat and add sour cream, cream of mushroom soup, drained corn, ½ cup of cheese. Stir until the cheese is melted.
  • Pour the mixture into the bottom of the baking dish and spread evenly.
  • Sprinkle ½ cup of cheese over the top of the casserole.
  • Layer the tater tots on top pressing them down into the mixture.
  • Sprinkle the remaining ½ cup of cheese over the top of the tater tots.
  • Sprinkle the chopped chives over the cheese.
  • Cover and bake at 425°F for 20 minutes. Uncover and bake for an additional 5-10 minutes.
  • Remove from oven and serve.


TIP: This is a fantastic make-ahead dish. You can prepare it up to the end of Step Six and store it in the fridge or freezer before baking it later.
TIP: By creating an even layer of tater tots you’ll get a nice, even amount of tater tots in each slice of your casserole (plus, it looks pretty)!
TIP: The higher cooking temperature is the temperature that tater tots are baked at. This ensures your tater tots are nice and crispy and not soggy.
