1 Preheat the oven to 425 degrees F (220 degrees C).
2 Coat a medium oval baking dish with cooking spray. Place half the Tater Tots in the dish; mash them gently to cover the bottom of the dish.
3 Par-bake in the preheated oven for about 10 minutes. Tater tot crust will not be fully cooked.
4 Meanwhile, heat a medium to large cast iron skillet over medium heat. Add hamburger and onion; cook and stir, using a spatula to break up the meat, for 5 minutes. Add mushrooms and continue to cook until meat is browned and vegetables are soft, about 5 minutes more. Drain grease if necessary.
5 Add ketchup, Worcestershire sauce, mustard, garlic powder, salt, and pepper. Cook until bubbly.
6 Transfer mixture into dish; spread evenly over Tater Tot crust. Top evenly with Swiss cheese slices, then distribute remaining tater tots evenly over cheese.
7 Bake in the preheated oven until casserole is bubbly and Tots are golden brown, about 30 minutes. Let cool for 5 minutes before serving.
