Preheat the oven to 375°F (190°C).

Brown the hot breakfast sausage in a skillet over medium heat, about 8-10 minutes.

Combine the cooked sausage with frozen tater tots, salt, pepper, garlic powder, onion powder, cheddar cheese, and mozzarella cheese in a large bowl.

Whisk together the eggs and milk in a separate bowl until frothy.

Pour the egg mixture over the sausage-tater tot blend and stir gently.

Transfer the mixture into a greased baking dish.

Bake in the preheated oven for 30-35 minutes, or until set and golden brown.
