Preheat the oven to 350 degrees F (180 degrees C). Lightly grease a 9x13-inch baking pan.
Remove the casing from the Breakfast Sausage (12 ounce). In a large skillet over medium-high heat, add the sausage and cook halfway through, 8 to 10 minutes. Drain fat if necessary.
Whisk together Egg (8), Whole Milk (1 cup), Salt (1 teaspoon), Ground Black Pepper (1/4 teaspoon), and Onion Powder (1 teaspoon).
In a large bowl, toss together Frozen Tater Tots (32 ounce), sausage and Cheddar Cheese (8 ounce). Pour into baking dish. Pour the egg mixture all over. Sprinkle more cheese if you wish.
Bake uncovered for 45 to 55 minutes, or until eggs are set.
