Ingredients

Scale
  • 1 (32 ounce) bag frozen tater tots
  • 1 pound breakfast sausage or bacon, cooked and crumbled
  • 1 cup chopped onion
  • 10 large eggs
  • 1 cup milk
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder
  • 2 cups shredded cheddar cheese, divided
  • 1 (10.5 ounce) can cream of mushroom soup

Instructions

  1. Grease a 9×13 inch baking dish.
  2. Arrange half of the frozen tater tots in a single layer on the bottom of the prepared dish.
  3. Sprinkle the cooked sausage or bacon and chopped onion evenly over the tater tots.
  4. In a large bowl, whisk together the eggs, milk, salt, pepper, and garlic powder.
  5. Stir in the cream of mushroom soup until combined.
  6. Pour the egg mixture evenly over the sausage and tater tots layer.
  7. Sprinkle 1 cup of the shredded cheddar cheese over the top.
  8. Arrange the remaining half of the tater tots over the cheese layer.
  9. Cover the dish tightly with plastic wrap or foil. Refrigerate for at least 4 hours or overnight.
  10. When ready to bake, preheat your oven to 375 degrees Fahrenheit. Remove the plastic wrap.
  11. Bake covered for 30 minutes.
  12. Remove the cover, sprinkle the remaining 1 cup of cheese over the top, and bake uncovered for another 15 to 20 minutes, or until the eggs are set and the tater tots are golden brown and crisp.
  13. Let the casserole rest for 5 minutes before slicing and serving.

Notes

  • For best results when making ahead, assemble the entire casserole through step 5, then cover and refrigerate. Add the cheese layers and top tater tots just before baking.
  • You can substitute ground turkey or ham for the sausage or bacon.
  • This casserole freezes well after baking; cool completely, wrap tightly, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
