Gluten Free Over-night Holiday Breakfast Casserole

I’d like to introduce myself;  My name is Mrs. James and I’m the cook at the GHOST compound.  I’d tell you more, but I’m under strict orders not to say more than is needed.  BUT, I can share some of my recipes, which PJ said I could do.  

It doesn’t have to be a holiday to make this recipe, and as the cook for a group of Special Operatives, I make this one a lot.  (One of our guys needs gluten free foods).  I can have it ready to go in the morning, (sometimes these folks start early), and all I need to do is pop it in the oven while they have their round table meeting to discuss the job at hand.  It’s simple, tasty and I get plenty of thank you’s and kudos for making this breakfast casserole a winner all around.

Gluten Free Over-night Holiday Breakfast Casserole


  • 6 cups cubed gluten-free white bread* (1" cubes)
  • 2 cups cubed pre-cooked ham (1/2" cubes), bacon or breakfast sausage
  • 2 cups shredded sharp cheddar cheese
  • 5 eggs
  • 2 cups milk
  • 1/2 tsp. dry mustard
  • 1/2 tsp. salt
  • 1/2 tsp. garlic powder
  • 1/4 cup salted butter, melted


  2. Lightly grease a 9x13 glass Pyrex baking dish.
  3. Mix cubed white bread and cubed ham in baking dish.
  4. Sprinkle with shredded cheese.
  5. In a bowl, beat the eggs, then mix in the milk, dry mustard, salt, and garlic powder.
  6. Pour over ham and bread mixture.
  7. Pour melted butter over all.
  8. Cover and refrigerate overnight.
  10. Remove casserole from refrigerator and uncover. Let sit at room temperature while oven preheats to 325°. Once oven is preheated, place uncovered casserole in oven and bake at 325° for an hour. Remove from oven. Let cool 5 minutes before cutting and serving.
  11. Refrigerate any leftovers.
  12. By way of full disclosure, I found this recipe from Michelle Palin in My Gluten-free Kitchen (Link on the blog post.)
  14. *I like using King Arthur's gluten-free bread mix to make a loaf a day or two before I make the casserole. It slices and cubes very nicely.
  15. Update 12/2014: I used gf Jules bread mix in my bread machine to make a loaf of bread for this. Turned out perfect and so easy!
