Tater Tot Hotdish

Step 1
Preheat the oven to 400 degrees F (200 degrees C)

Step 2
Set a large deep cast iron skillet over medium-high heat. Add olive oil and swirl to coat skillet evenly. Add onions to skillet in one even layer; top with ground beef, breaking it up into small pieces. Cook undisturbed until onions are translucent, about 2 minutes. Stir beef and onions until well combined, and cook until beef is cooked through and browned, stirring occasionally, 3 to 4 minutes longer.

Step 3
Reduce heat to medium. Season beef with garlic powder, onion powder, and black pepper. Cook, stirring often, for 1 more minute. Remove from heat. Add cream of mushroom soup, green beans, and corn; stir until well combined.

Step 4
Toss tater tots and seasoned salt in a bowl to combine. Arrange tater tots decoratively over beef mixture in the skillet, avoiding large gaps between tots.

Step 5
Bake in the preheated oven until tater tots are golden and crisp, about 1 hour. Sprinkle with cheese and scallions; cool 10 minutes before serving.
