Christmas Breakfast Casserole

Festive, sturdy breakfast casserole, with eggs, sausage, and cheese, is delicious enough to save for a special holiday, but this practical recipe is also perfect for weeknight meals too! Make ahead and refrigerate overnight so that the flavors meld — it’s a little bit of Christmas that can be savored all year long!
Servings 10


  • 6 eggs beaten
  • 2 c grated cheddar cheese
  • 1 tsp dry mustard
  • 1/2 tsp salt
  • 6 slices of bread cubed (if you have leftover crust for some reason, like I did, you basically need enough to fill the casserole dish)
  • 1 lb sausage browned and drained (I recommend turkey sausage.)
  • 1/4 tsp pepper
  • 2 c milk
  • butter flavored cooking spray


  1. Mix all the ingredients and put into a well-buttered baking dish (I used spray to save calories!).

  2. Let set 12 hours in refrigerator.

  3. Bake for 45 minutes at 350. 

  4. Whether it’s Christmas morning brunch or the middle of the night in summer, serve and enjoy!

Recipe Notes

Don’t use multigrain bread or bread with seeds that doesn’t have a soft texture. I did that once, and the change in texture isn’t something that I would recommend. I’m normally willing to sacrifice in the name of health, but this just wasn’t worth it. White bread or soft wheat bread is best.
