This hearty tater tot breakfast casserole is the perfect make-ahead dish for busy mornings, brunch with friends, or a comforting weekend meal. With layers of savory sausage, fluffy eggs, melted cheese, and golden crispy tots on top, every bite delivers cozy flavor and satisfying crunch. Follow these simple steps to bring it all together with ease.
- Prep the dish and oven
Preheat your oven to 350°F (175°C). Lightly spray a 2-quart or 9x13 baking dish with cooking spray.
- Cook the sausage and onions
In a skillet over medium-high heat, cook the sausage and diced onion until browned and crumbly, about 5-7 minutes. Drain off any extra fat.
- Whisk the egg mixture
In a large bowl, whisk together the milk, eggs, onion powder, salt, garlic powder, and black pepper.
- Assemble the casserole
Spread the sausage and onion mixture evenly on the bottom of your baking dish. Pour the egg mixture on top. Sprinkle with half the cheese. Arrange all the frozen tater tots in a single layer over the cheese.
- Bake and finish with cheese
Cover with foil and bake for 40 minutes. Remove the foil, top with the remaining cheese, and bake for another 15-20 minutes, until the tots are golden and the cheese is melted. Let it rest for 5-10 minutes before serving.
Tips!
- Always drain the sausage well to keep the casserole from getting greasy.
- Don't skip the rest time after baking - it helps the casserole set.
- Want extra crispy tots? Broil for 2-3 minutes at the end.

Leftovers can be stored in an airtight container in the fridge for up to 4 days. To reheat, bake at 350°F for about 15 minutes or microwave individual portions.
