Creating your own Tater Tot Casserole is simple! Follow these steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Brown the Meat: In a skillet over medium heat, brown the ground beef or turkey until fully cooked. Drain excess fat and set aside.
3. Sauté Vegetables: In the same skillet, add the diced onion and cook until softened, about 3-4 minutes.
4. Mix the Filling: In a large bowl, combine the cooked meat, cream of mushroom soup, sour cream, garlic powder, salt, pepper, and mixed vegetables if using. Stir until well blended.
5. Add Cheese: Mix in ½ cup of the shredded cheddar cheese to the meat mixture.
6. Assemble Casserole: Spread the meat mixture evenly in a greased 9×13-inch baking dish.
7. Add Tater Tots: Top the meat mixture with a single layer of tater tots, covering the entire surface.
8. Bake: Place the casserole in the preheated oven and bake for 40-45 minutes until the tater tots are golden brown and the mixture is bubbling.
9. Add Remaining Cheese: In the last 5 minutes of baking, sprinkle the remaining ½ cup of cheddar cheese on top.
10. Cool Slightly: Remove the casserole from the oven and let it cool for about 5 minutes before serving.

Follow these straightforward steps, and you’ll have a sensational Tater Tot Casserole to delight your family or guests.
