1 pound lean ground beef
½ medium onion, chopped
3 cloves garlic, minced
1 tablespoon Worcestershire sauce
½ teaspoon Italian seasoning
½ cup sour cream
1 (10.5-ounce) can condensed cream of mushroom soup
1 (12-ounce) can corn, drained
2 cups shredded cheddar cheese, divided
32 ounces frozen tater tots
Salt and pepper, to taste
Chopped scallions (optional, for serving)
Preheat the Oven
Preheat your oven to 375°F (190°C) and move the rack to the top third of the oven.
Brown the Beef
In a large skillet over medium-high heat, cook the ground beef and onions, breaking the meat apart, until the beef is browned and the onions are soft (about 7–8 minutes). Spoon off excess grease if needed.
Add Flavor
Stir in the garlic, Worcestershire sauce, and Italian seasoning. Cook for about 1 minute, until fragrant.
Make It Creamy
Reduce heat to medium. Stir in the sour cream, condensed soup, corn, and about ½ cup of the shredded cheddar. Mix well and heat for 1–2 minutes.
Assemble the Casserole
Transfer the mixture to a 9×13-inch baking dish and spread it evenly. Sprinkle the remaining cheddar cheese over the top, then arrange the frozen tater tots in an even layer.
Bake
Bake uncovered for 45 minutes, or until the tater tots are golden brown and the cheese is melted and bubbly.
Serve
Garnish with chopped scallions if desired. Taste and add salt and pepper as needed before serving.
Use lean ground beef to avoid excess grease.
For extra crispiness, bake the casserole on the top rack as directed.
Swap corn for peas or green beans if you prefer.
Sharp cheddar adds more flavor, but mild works great for kids.
Leftovers reheat well in the oven or air fryer to keep the tots crispy.
