Preheat your oven to 375°F (190°C).
In a large skillet over medium heat, cook the ground beef, breaking it apart with a spatula, until browned, about 5-7 minutes. Drain excess fat.
Add the diced onion and minced garlic to the skillet with the beef. Cook until the onion is translucent, about 3-4 minutes.
Stir in the cream of mushroom soup, sour cream, and shredded cheddar cheese. Mix until well combined and creamy.
Add the frozen mixed vegetables, salt, black pepper, and paprika to the skillet. Stir to combine all ingredients evenly.
Pour the mixture into a greased 9x13-inch baking dish, spreading it into an even layer.
Arrange the tater tots on top of the mixture, ensuring they cover the surface in a single layer.
Bake in the preheated oven for 30-35 minutes, or until the tater tots are golden brown and crispy.
Remove from the oven and let it sit for 5 minutes before serving.
