In a large skillet over medium-high heat, brown the ground beef with diced onion and minced garlic until no pink remains, about 8 minutes. Drain excess fat and season with salt and pepper.
1 lb lean ground beef, 1 cup diced onion, 2 cloves garlic, 0.5 tsp salt, 0.25 tsp black pepper
Sauce
Sprinkle flour over the meat mixture and stir for 1 minute. Add both cans of cream of mushroom soup and milk, stirring until smooth. Simmer for 3–4 minutes until bubbling and slightly thickened.
Preheat oven to 375°F. Spread the beef-sauce mixture evenly in a greased 9×13″ baking dish. Sprinkle shredded cheddar cheese over the top, then arrange tater tots in a single layer.
0.5 cup milk
Bake uncovered for 35–40 minutes until the tots are golden and crisp and the cheese is bubbling. Let stand 5 minutes before serving.
