I know the title says Green Bean & Tator Tot Hamburger Casserole but trust me when I say that it is SO MUCH MORE than just any ordinary casserole.


  • 5 cups of frozen green beans boiled and drained
  • 10-12 oz of fresh mushrooms chopped
  • 2 tablespoons butter
  • 1 celery stalk chopped into little bitty pieces
  • 1 medium yellow onion
  • 1 1/4 cup mayonnaise
  • 1/2 cup heavy cream
  • Salt to taste
  • 1/2 teaspoon of ground black pepper
  • 2 teaspoons minced garlic divided
  • 1 1/2 cups shredded monterey / colby jack cheese
  • 1 cup shredded mozzarella cheese
  • 1.25 pound package of ground beef I used 85/15 Organic from Costco


  1. Preheat oven to 400°. Place your tots in the bottom of a buttered 9x13 casserole dish and place in the oven and cook for 12 minutes while you prepare the other ingredients.
  2. Cook your ground beef in a large skillet over medium heat until cooked through and browned. I usually try to get the hamburger pieces as small as I can (we don't like big chunks of hamburger in our casseroles). Drain the grease and set the hamburger aside on a plate or in a bowl.
  3. Wipe out your skillet with a napkin to remove the hamburger grease.
  4. Add your chopped celery, mushrooms, onions, butter and 1 teaspoon of garlic to the skillet and cook until all are tender and cooked through.
  5. In a medium mixing bowl combine your mayonnaise, heavy cream, salt, pepper, and 1 teaspoon minced garlic. Mix well. Add your cheeses and stir again to incorporate everything together.
  6. Add your cooked drained green beans and cooked hamburger & onion mixture to your bowl and stir to mix everything together.
  7. Take your casserole dish out of the oven and put the hamburger mixture over the top of the tator tots. Spread evenly and place in the oven to bake for approximately 25 minutes.
  8. You'll know it's done when the sides are bubbling and the top starts to brown slightly.
  9. Serve and enjoy!
