Making the Tater Tot Breakfast Casserole is easy when you follow these simple steps:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray.
2. Cook the meat: In a skillet over medium heat, cook the breakfast sausage or bacon until fully cooked. Drain excess grease, if necessary.
3. Whisk the eggs: In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, black pepper, and salt until well combined.
4. Layer the ingredients: Spread half of the frozen tater tots in an even layer at the bottom of the prepared baking dish.
5. Add the meat: Pour the cooked sausage or bacon evenly over the tater tots.
6. Add the cheese: Sprinkle one cup of shredded cheddar cheese over the meat layer.
7. Pour the egg mixture: Pour the egg mixture evenly over the layers in the baking dish.
8. Top with tater tots: Place the remaining tater tots on top of the egg mixture, covering it evenly.
9. Sprinkle cheese: Top the tater tots with the remaining cup of cheddar cheese.
10. Bake the casserole: Place the dish in the oven and bake for 35-40 minutes, or until the eggs are set, and the tops are golden brown and crispy.
11. Rest and garnish: Once out of the oven, let the casserole sit for a few minutes. Garnish with chopped green onions or parsley if desired.
