Ingredients

  • 1 onion diced
  • 1 1/2 pounds ground beef
  • 1 cup mushrooms coarsely chopped
  • 1/3 cup flour (or 3 tablespoons cornstarch)
  • 2 cups milk
  • 2 tablespoons beef bouillon
  • kosher salt to taste
  • ground black pepper to taste
  • 1 (12-14 oz.) can cut green beans drained, optional
  • 1 (12-16 oz.) package frozen tater tots
  • 2 cups cheddar cheese shredded

Instructions

  • Preheat oven to 375-degrees.
  • In a large skillet over medium heat, cook onion and ground beef until beef JUST browned. Add mushrooms and cook until beef is cooked through and onion is translucent. Drain excess grease.
  • Sprinkle flour over beef/mushroom mixture and stir until flour coats the beef.
  • Slowly stir in the milk, stirring constantly until you reach your desired thickness (you want the sauce to have the consistency of a thick gravy). You may or may not need all the milk.
  • Season with beef bouillon and salt and pepper to taste. Stir in green beans (optional).
  • Spray a 9x13 baking dish with cooking spray and pour beef mixture into the bottom of the dish, spreading evenly.
  • Evenly layer tater tots over the beef mixture.
  • Bake for 35-40 minutes or until tater tots become golden brown and crispy.
  • Remove from oven, top with cheese, and bake an additional 5 minutes.
  • Serve immediately.
