Christmas Breakfast Casserole

Start your Christmas morning with a warm, comforting breakfast casserole that fills your home with delightful aromas. This easy-to-make dish is perfect for a cozy holiday breakfast, bringing together savory sausage, creamy eggs, and melted cheese in every bite.

Ingredients (Servings: 6)

  • 1 lb ground sausage
  • 1 tsp mustard powder
  • ½ tsp kosher salt
  • 4 large eggs, beaten
  • 2 cups whole milk
  • 6 slices white bread, toasted and cut into cubes
  • 1 cup mild Cheddar cheese, shredded

How To Make Christmas Breakfast Casserole

  1. Cook the Sausage:
  • Crumble the sausage into a medium skillet and cook over medium heat until evenly browned. Drain the excess fat and set the sausage aside.
  1. Prepare the Egg Mixture:
  • In a medium bowl, mix together the mustard powder, kosher salt, beaten eggs, and whole milk until well combined.
  1. Assemble the Casserole:
  • Add the cooked sausage, toasted bread cubes, and shredded Cheddar cheese to the bowl with the egg mixture. Stir until everything is evenly coated.
  1. Chill the Casserole:
  • Pour the mixture into a greased 9×13 inch baking dish. Cover the dish and chill in the refrigerator for at least 8 hours or overnight. This allows the flavors to meld and the bread to absorb the egg mixture.
  1. Bake the Casserole:
  • Preheat your oven to 350 degrees Fahrenheit. Keep the casserole covered and bake for 45 to 60 minutes.
  1. Finish Baking:
  • Uncover the casserole and reduce the oven temperature to 325 degrees Fahrenheit. Bake for an additional 30 minutes, or until the casserole is set and the top is golden brown.
  1. Serve:
  • Let the casserole cool slightly before cutting into squares. Serve warm and enjoy a delicious start to your Christmas morning!


This Christmas Breakfast Casserole is sure to become a holiday tradition in your home. It’s simple to prepare, can be made ahead of time, and is absolutely delicious. Merry Christmas and happy cooking!
