Ingredients

1 tablespoon (15 ml) olive oil
1 pound (450 g) ground beef (80–85% lean)
½ medium yellow onion, finely diced
2 cloves garlic, minced
1 (14-ounce / 400 g) can diced tomatoes
2 cups (320 g) frozen corn, thawed
½ cup (120 g) sour cream
2 cups shredded cheddar cheese, divided
Salt and pepper, to taste
32 ounces (900 g) frozen tater tots
2 tablespoons fresh parsley, finely chopped

Instructions

Preheat Oven:
Set your oven to 375°F (190°C).
Cook the Beef:
In a Dutch oven or large skillet, heat olive oil over medium heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until no longer pink. Drain excess fat if needed. Season with salt and pepper.
Add Aromatics:
Stir in the diced onion and cook for 2–3 minutes until translucent. Add garlic and cook for an additional 30 seconds until fragrant.
Make the Creamy Mixture:
Add the diced tomatoes, thawed corn, sour cream, and 1 cup of shredded cheddar. Stir until the cheese melts and the mixture is well combined. Remove from heat.
Assemble the Casserole:
Pour the beef and vegetable mixture into a casserole dish. Top with the remaining 1 cup of cheddar cheese, then arrange tater tots evenly over the top.
Bake:
Bake for 30–35 minutes, or until the tater tots are golden brown and crispy.
Garnish and Serve:
Sprinkle with fresh parsley before serving. Serve warm.
