This tater tot ground beef casserole is a comforting, family-friendly dish made with seasoned beef, vegetables, creamy sauce, melted cheese, and crispy golden tater tots baked to perfection.
Preheat oven to 375°F (190°C) and grease a 9x13-inch baking dish.
In a large skillet, brown ground beef over medium-high heat, breaking it apart as it cooks.
Add diced onion and cook until softened, then stir in garlic and cook until fragrant.
Drain excess fat, then stir in Worcestershire sauce, mixed vegetables, salt, and pepper.
In a bowl, mix cream of mushroom soup and sour cream until smooth, then combine with beef mixture.
Spread half of the beef mixture into the baking dish and top with 1 cup cheese.
Add remaining beef mixture and top with remaining cheese.
Arrange frozen tater tots evenly over the top.
Bake uncovered for 40–45 minutes until golden and crispy.
Let rest for 5 minutes before serving.
Notes
Use frozen tater tots for best crispiness. Let casserole rest 5 minutes before serving. Store leftovers in the fridge for up to 3–4 days or freeze up to 3 months. Reheat in oven for best texture.
