Ingredients Equipment Method Notes

Ingredients
  

  • 1 cooking spray
  • 1 lb breakfast sausage
  • 0.5 cup yellow onion finely diced
  • 8 eggs large
  • 2 cup whole milk
  • 1 tsp kosher salt
  • 0.5 tsp black pepper
  • 2 cup sharp cheddar cheese shredded
  • 1 package (32 oz) tater tots frozen

Equipment

  • 1 9x13-inch baking dish
  • 1 large skillet

Method
 

  1. Heat the oven to 375°F.
  2. Coat a 9x13-inch baking dish with cooking spray.
  3. Cook the sausage and onion in a large skillet over medium heat, breaking up the sausage, until the sausage is no longer pink and the onion is tender, 8 to 10 minutes.
  4. Drain off excess grease.
  5. Whisk the eggs, milk, salt, and pepper in a large bowl until combined.
  6. Spread the sausage mixture in the prepared dish.
  7. Sprinkle with the cheese.
  8. Pour the egg mixture evenly over it.
  9. Arrange the frozen tater tots in a single layer on top.
  10. Bake uncovered for 55 to 65 minutes, until the tots are golden brown and the center of the casserole reaches 160°F on an instant-read thermometer.
  11. Let the casserole rest for 10 minutes before serving.

Notes

For an even bake, arrange the tater tots in a single layer. Store covered in the refrigerator for 3 to 4 days; freeze individual portions for up to 2 months. For a dairy-free swap, use unsweetened dairy-free milk and dairy-free cheddar.
