Equipment

  • 9x13 inch baking dish
  • Large skillet or Dutch oven
  • Knife
  • Cutting board
  • Cheese grater
  • Spatula or large spoon

Ingredients
  

  • 1.5 pounds 85/15 or 90/10 lean ground beef
  • 1 tablespoon olive oil
  • 1 medium yellow onion, finely diced
  • 3 cloves garlic, minced
  • 1.5 cups full-fat sour cream
  • ½ cup whole milk
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • 1 teaspoon paprika
  • Salt and black pepper to taste
  • 3 cups sharp cheddar cheese, freshly shredded and divided

Instructions
 

  • Preheat your oven to 400°F (200°C). Lightly grease a 9x13 inch baking dish.
  • In a large skillet or Dutch oven, heat the olive oil over medium-high heat. Add the diced onion and cook for 4-5 minutes, until softened.
  • Add the ground beef to the skillet. Break it apart with a spoon and cook until nicely browned. Drain off any excess grease.
  • Stir in the minced garlic and cook for another minute until fragrant.
  • Reduce the heat to low. Add the sour cream, milk, Worcestershire sauce, onion powder, garlic powder, paprika, salt, and pepper. Stir until a cohesive, creamy sauce forms.
  • Stir in the frozen corn and 2 cups of the shredded cheddar cheese. Continue stirring until the cheese is just beginning to melt and everything is well combined.
  • Pour the beef mixture into the prepared baking dish and spread it into an even layer.
  • Arrange the frozen tater tots in a single, even layer over the top of the beef mixture, covering the entire surface.
  • Place the casserole in the preheated oven and bake for 30 minutes, until the tots are starting to look golden brown.
  • Carefully remove the dish from the oven and sprinkle the remaining 1 cup of shredded cheddar cheese evenly over the tater tots.
  • Return the casserole to the oven and bake for another 10-15 minutes, until the cheese is fully melted and bubbly and the tots are a deep golden brown.
  • Let the casserole rest for at least 5-10 minutes before serving to allow the filling to set. Garnish with fresh parsley or chives if desired.

Notes

Pro Tips for Success:
- For the best texture, always drain the excess grease after browning the beef.
- Shred your own cheese from a block. Pre-shredded cheese contains anti-caking agents that prevent it from melting smoothly.
- Ensure the tater tots are in a single, even layer for the crispiest possible topping.
Variations & Flavor Boosts:
- Meat: Ground turkey, ground chicken, or spicy Italian sausage can be used instead of beef.
- Vegetables: Feel free to add sautéed mushrooms, bell peppers, or a bag of frozen mixed peas and carrots.
- Cheese: Colby Jack, Monterey Jack, or Pepper Jack are great alternatives to cheddar.
- Spice it Up: Add a dash of hot sauce, a pinch of red pepper flakes, or a can of drained green chiles to the beef mixture for a smoky, spicy kick.
