This easy breakfast casserole combines tater tots, eggs, sausage, and cheese into a hearty, crowd-pleasing dish that’s great for mornings when you need something filling and simple.
Preheat the oven to 350°F and grease a 9×13-inch baking dish.
In a large skillet, cook 1 lb hot breakfast sausage over medium heat until browned and no longer pink. Drain any excess grease.
Spread 1 bag (28–32 oz) frozen tater tots evenly in the prepared baking dish.
Sprinkle the cooked sausage over the tater tots, then top with 1 cup shredded cheddar cheese from the 2 cups total.
In a large bowl, whisk together 12 large eggs, 1/2 cup milk, 1 teaspoon salt, 1/2 teaspoon black pepper, 1/2 teaspoon garlic powder, and 1/2 teaspoon onion powder until well combined.
Pour the egg mixture evenly over the tater tots, sausage, and cheese.
Bake for 35–40 minutes, or until the eggs are set in the center.
Sprinkle the remaining 1 cup shredded cheddar cheese evenly over the casserole and bake an additional 5 minutes, until the cheese is melted.
Let the casserole rest for 10 minutes before slicing and serving.
Notes
Substitute cooked bacon or diced ham for the sausage if desired.To make ahead, assemble and refrigerate overnight.Let sit at room temperature while the oven preheats and add 10–15 minutes to the bake time until the eggs are fully set. Refrigerate leftovers in an airtight container for up to 3–4 days.
