Preheat the Oven:

Preheat your oven to 350°F (175°C).

Cook the Sausage:

In a skillet over medium heat, cook the crumbled sausage until browned and fully cooked. Drain excess fat and set aside.

Layer the Casserole:

In a large glass baking dish, spread half of the tater tots evenly on the bottom. Top with the cooked sausage.

Prepare the Egg Mixture:

In a bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and pepper.

Combine and Bake:

Pour the egg mixture over the tater tots and sausage. Top with the remaining tater tots and sprinkle the shredded cheddar and mozzarella cheese on top.

Bake the Casserole:

Bake in the preheated oven for 35-40 minutes, or until the eggs are set and the cheese is golden and bubbly.

Serve:

Let it cool slightly before serving. Garnish with fresh parsley if desired.
