Minnesota hot dish combines ground beef, tater tots, vegetables, and cream of mushroom soup in a classic Midwestern family casserole. This protein-packed, budget-friendly comfort food defines Midwest home cooking.
Preheat the oven to 375°F and grease a 9x13-inch casserole dish.
In a large skillet over medium-high heat, sauté diced onion and minced garlic for 2–3 minutes until fragrant, then add ground beef and cook thoroughly, stirring frequently; drain excess fat.
Stir in frozen mixed vegetables and cream of mushroom soup into the cooked beef mixture; add salt and pepper. Mix well, then spread evenly in the prepared casserole dish.
Arrange tater tots in a single, tightly-packed layer over the beef and vegetable mixture. Sprinkle shredded cheddar cheese evenly across the top.
Bake uncovered for 35–40 minutes on the middle rack, until tater tots are golden brown and crispy, and the cheese is bubbling. Let sit for 10 minutes before serving to set texture.
