Ingredients Method Notes

Ingredients
  

  • 1 lb 450 g lean ground beef (90% lean)
  • 1 small yellow onion finely diced
  • 2 cloves garlic minced
  • 1 can 10.5 oz / 298 g condensed cream of mushroom soup
  • 1/2 cup sour cream
  • 1 teaspoon Worcestershire sauce
  • 1/2 teaspoon garlic powder
  • Salt and black pepper to taste
  • 2 cups shredded cheddar cheese divided
  • 1 bag 32 oz / 900 g frozen tater tots
  • 2 tablespoons sliced green onions for garnish (optional)

Method
 

  1. Preheat the oven to 425°F (220°C). Lightly grease a 9x13-inch baking dish.
  2. Cook the ground beef and onion in a large skillet over medium heat, breaking the beef into crumbles, until browned and the onion is soft. Drain extra fat. Add the garlic for 30 seconds.
  3. Stir in the cream of mushroom soup, sour cream, Worcestershire sauce, garlic powder, salt, and pepper. Simmer 2 minutes, then stir in 1 cup of the cheddar until melted.
  4. Spread the beef mixture evenly in the baking dish.
  5. Sprinkle the remaining 1 cup of cheddar over the filling.
  6. Arrange the frozen tater tots in a single layer in neat rows over the cheese, covering the whole surface.
  7. Bake 35-40 minutes, until the tots are deep golden and crispy and the filling is bubbling at the edges.
  8. Rest 5 minutes, scatter with green onions if using, and serve hot.

Notes

Keep the tots frozen and in a single layer so they crisp properly. Leftovers keep 3 days in the fridge; reheat in the oven to bring back the crunch.
