Preheat your oven to 350°F.

In a skillet, brown the hot breakfast sausage over medium heat for 6-8 minutes.

In a large mixing bowl, stir together the cooked sausage, frozen tater tots, salt, pepper, garlic powder, and onion powder.

Grease a baking dish and spread the sausage and tater tot mixture evenly across the bottom.

In another bowl, whisk together the eggs and milk until well combined.

Pour the egg and milk mixture over the tater tot and sausage combination.

Sprinkle the shredded cheddar and mozzarella cheeses over the top.

Bake the casserole for 30-40 minutes until the eggs are set and the top is golden brown.
