Tater tot hot dish layers crispy tater tots over seasoned ground beef and creamy sauce for the ultimate Minnesota family casserole. This protein-packed comfort food is a Midwestern weeknight staple.
Preheat oven to 375°F (190°C).
In a large skillet over medium-high heat, cook ground beef, stirring and breaking up, until browned. Drain excess fat.
Add diced onion to the skillet and sauté for 3-4 minutes until softened, then stir in frozen mixed vegetables and cook for 2 more minutes.
Mix in cream of mushroom soup, salt, pepper, and garlic powder; combine thoroughly and simmer for 2 minutes to meld flavors.
Transfer beef mixture into a 9x13-inch baking dish, sprinkle cheddar cheese evenly over the top, then arrange frozen tater tots in a single layer.
Bake uncovered for 35-40 minutes until tater tots are golden brown and crispy; let cool for 10 minutes before serving.
