Ingredients Equipment Method Notes

Ingredients
  

  • 1.5 lbs ground beef 90/10 lean-to-fat ratio
  • 1 medium yellow onion, finely diced
  • 3 cloves garlic, minced
  • 1 cup full-fat sour cream
  • 1/2 cup whole milk
  • 3 cups shredded cheddar cheese, divided
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon paprika
  • 1/2 teaspoon black pepper
  • Salt to taste
  • 1 tablespoon cooking oil if needed for browning

Equipment

  • 9x13 inch baking dish
  • Large rimmed baking sheet
  • Large skillet or Dutch oven
  • Mixing Spoon
  • Cheese grater (if using block cheese)
  • Measuring cups and spoons
  • Cutting board
  • Chef's knife

Method
 

  1. Preheat oven to 425°F (218°C). Grease a 9x13 inch baking dish.
  2. Spread the frozen tater tots in a single layer on a large rimmed baking sheet. Bake for 15 minutes to par-crisp. Remove from oven but leave oven on.
  3. While tots bake, brown the ground beef in a large skillet over medium-high heat, breaking it into small crumbles. Season with salt. Drain excess fat if necessary.
  4. Add the diced onion to the skillet with the beef. Cook for 5-6 minutes until softened. Add the minced garlic and cook for 30 seconds until fragrant.
  5. Reduce heat to medium. Stir in the cream of mushroom soup, sour cream, milk, Worcestershire sauce, paprika, and black pepper. Simmer for 5-7 minutes, stirring often, until the mixture thickens.
  6. Remove the skillet from heat. Stir in 2 cups of the shredded cheddar cheese until melted and fully incorporated.
  7. Transfer the beef and cheese mixture to the prepared baking dish, spreading it into an even layer.
  8. Arrange the par-baked tater tots tightly in a single layer over the filling.
  9. Sprinkle the remaining 1 cup of cheddar cheese evenly over the tater tots.
  10. Bake at 425°F for 25-30 minutes, or until the tots are deep golden brown and the filling is bubbling at the edges. For extra crispness, broil for the final 1-2 minutes, watching closely.
  11. Remove the casserole from the oven and let it rest for 10-15 minutes before serving to allow the filling to set.

Notes

For the best melt, shred cheese from a block instead of using pre-shredded. Do not thaw the tater tots before the first bake. The simmering step to thicken the filling is crucial to prevent a runny base that steams the topping. Letting the casserole rest ensures clean slices. Store leftovers covered in the refrigerator for up to 4 days. Reheat in the oven or toaster oven to maintain crispness. Variations: Try the 'Everything Bagel' twist by mixing seasoning into the sour cream, or make a Buffalo Chicken version with rotisserie chicken and ranch.
