Making Tater Tot Casserole is a seamless process if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Brown the Meat: In a large skillet, cook the ground beef over medium heat until browned. Drain excess fat.
3. Add Onions: Stir in the diced onion and cook until translucent, about 3-5 minutes.
4. Season and Mix: Add salt, pepper, garlic powder, and paprika if using. Mix in the cream of mushroom soup and frozen vegetables. Stir until everything is well combined.
5. Layer the Casserole: Spread the beef and vegetable mixture evenly in a 9×13 inch baking dish.
6. Add Cheese Layer: Sprinkle half of the shredded cheddar cheese on top of the meat mixture.
7. Arrange Tater Tots: Carefully arrange the frozen tater tots in a single layer over the cheese.
8. Final Cheese Layer: Top the tater tots with the remaining cheddar cheese.
9. Bake: Place the baking dish in the preheated oven and bake for 30-35 minutes, or until the tater tots are golden brown.
10. Cool and Serve: Let the casserole cool for a few minutes before serving. This makes it easier to cut into portions.
