Tater Tot Breakfast Casserole Instructions

Preheat the oven to 375°F. Lightly grease a 9×13-inch baking dish.
Cook the breakfast sausage in a large skillet over medium heat, breaking it into crumbles as it cooks. Continue cooking until browned and fully cooked. Drain any excess grease.
Spread the cooked sausage evenly across the bottom of the prepared baking dish.
Sprinkle 1 1/2 cups of the shredded cheddar cheese over the sausage.
In a large bowl, whisk together the eggs, milk, garlic powder, onion powder, salt, and black pepper until well combined.
Pour the egg mixture evenly over the sausage and cheese.
Arrange the frozen tater tots in a single layer over the top of the casserole.
Sprinkle the remaining 1/2 cup cheddar cheese over the tater tots.
Bake uncovered for 45 to 50 minutes, or until the eggs are fully set and the tater tots are golden and crisp.
Let the casserole rest for about 10 minutes before slicing.
Garnish with sliced green onions, if desired, and serve warm.

How to Know When It’s Done

The center of the casserole should be fully set and no longer look wet or jiggly. The tater tots should be browned and crisp on top.

For extra accuracy, the egg mixture should reach 160°F in the center.

Make-Ahead Option

You can cook the sausage and assemble the egg-and-sausage portion the night before.

For the crispiest result, add the frozen tater tots just before baking rather than refrigerating them on top overnight.

Cover the casserole and refrigerate overnight. When ready to bake, add the tater tots and cheese, then bake as directed.

Storage

Store leftovers in an airtight container in the refrigerator for up to 3 to 4 days.

Reheating and Freezing

For the best texture, reheat individual portions in the air fryer or oven so the tater tots stay crisp.

You can also microwave portions until hot, although the tots will be softer.

Let the baked casserole cool completely, then wrap tightly or divide into individual portions.

Freeze for up to 2 to 3 months.

Thaw overnight in the refrigerator before reheating.
