A fun and easy tater tot Cowboy Casserole with ground beef, onions, green beans, corn, tomatoes and plenty of Cheddar and Monterey Jack Cheese. 


  • 1 lb. ground beef
  • ½ medium onion finely chopped
  • 2 cloves garlic minced
  • 1 teaspoon marjoram
  • ½ teaspoon dried thyme leaves
  • ¼ teaspoon crushed red pepper
  • 2 1/2 cups low sodium beef broth
  • 2 teaspoons Worcestershire Sauce
  • 1 ½ cups trimmed and chopped green beans
  • 2 tablespoons cornstarch
  • ¼ cup water
  • 1 can (15.25 ounces) corn drained
  • 1 can (14.5 ounce) fire roasted tomatoes
  • salt and pepper to taste
  • 1 bag (32 ounces) frozen tater tots
  • 2 cup shredded Cheddar and Monterey Jack cheese


  1. Brown your ground beef over medium heat. About halfway through the browning process add the chopped onion. Continue cooking until the ground beef is browned and the onions are soft. Add the garlic, marjoram, thyme, and crushed red pepper cooking for 1 minute while stirring constantly.
  2. Preheat oven to 375 degrees.  Spray 11×7 inch casserole dish with nonstick baking spray. 
  3. Add the beef broth, Worcestershire sauce, and green beans to the ground beef mixture. Simmer for 15 minutes. In a small bowl whisk the cornstarch and water together. Whisk it into the beef mixture. Add the corn and tomatoes; simmering until thickened. Add salt and pepper to taste.
  4. Meanwhile layer tater tots in the bottom of prepared casserole dish in a single layer. Bake in a preheated oven for 15 minutes or until lightly browned. Spread half the cheese over the baked tater tots. Spoon the thickened hamburger mixture on to the tater tots and top with the remaining tater tots. Sprinkle with the remaining cheese.
  5. Bake uncovered for 30 minutes or until the tater tots are crispy and the cheese is melted.


  • Before layering the bottom of the casserole dish with tater tots count them and make sure you have enough to cover the top. You want to make sure your casserole looks aesthetically pleasing from the top.
  • Simmer the gravy until the beans are tender and until it is thickened.
  • A layer of cheese on top of the bottom layer of tater tots helps keep them crisp during preparation.
  • If you don’t like an ingredient substitute something similar. If you don’t like green beans try peas.
  • For a kicked up spicy version add a little minced jalapeno, cayenne pepper, or more red pepper flakes.
  • Store leftovers in an air tight container in the fridge for up to 3 days. Or store in a freezer sturdy container for up to 2 months.
  • This casserole is best reheated in the oven at 375 degrees for about 20-25 minutes or until warm.
