Creating this Simple and Delicious Tater Tot Casserole is incredibly easy! Just follow these simple steps:

1. Preheat Oven: Start by preheating your oven to 350°F (175°C).
2. Cook Beef: In a skillet over medium heat, brown the ground beef along with the diced onion. Cook until the meat is no longer pink, about 5-7 minutes.
3. Add Flavor: Stir in the garlic powder, onion powder, salt, and pepper to taste while the beef cooks.
4. Mix Ingredients: In a large mixing bowl, combine the cooked beef mixture, cream of mushroom soup, and frozen mixed vegetables. Stir until everything is well combined.
5. Layer Mixture: Spread the beef and vegetable mixture evenly in a greased 9×13-inch baking dish.
6. Add Cheese: Sprinkle the shredded cheddar cheese over the beef mixture for added flavor.
7. Top with Tater Tots: Place the frozen tater tots in a single layer on top of the cheese. Make sure to cover the entire surface for a crispy top.
8. Bake: Place the baking dish in the preheated oven and bake for 30 minutes, or until the tater tots are golden brown and crispy.
9. Cool and Serve: Once done, let the casserole cool for a few minutes before serving. Optionally, sprinkle chopped green onions on top for garnish.

These steps exhibit how straightforward and enjoyable preparing this casserole can be—perfect for novice cooks or anyone short on time!
