Preheat oven to 400°F; spray a 9x13-inch baking dish with cooking spray.

Spread 1 bag (32 oz) frozen tater tots in a single layer on a baking sheet.

Bake 15 minutes to partially cook and crisp; remove and set aside.

Reduce oven temperature to 350°F.

Cook 1 pound breakfast sausage in a large skillet over medium, crumbling, until browned and cooked through to 160°F; drain excess fat.

Whisk 12 eggs, 1 cup milk, 1 teaspoon salt, ½ teaspoon black pepper, and ½ teaspoon garlic powder in a large bowl.

Spread sausage evenly in prepared dish.

Pour the egg mixture over the sausage.

Sprinkle eggs with 2 cups shredded cheddar.

Arrange partially baked tots evenly on top.

Bake uncovered for 40-50 minutes, until eggs are set and the center reaches 165°F. If the top browns early, tent loosely with foil.

Rest 10 minutes before serving.

Cut into squares and serve with hot sauce or ketchup.
