Cubing Sandwich loaf, Bread

I Found this Christmas that No Store had Stuffing for my Turkey, But I had a loaf of frozen White Sandwich Bread in the freezer, I removed it, Still frozen, and it cubed easily, 4 Slices at a time, and I had near perfect Cubes, just thought it might help someone who doesn't like "Flat Cubes" that you get from cubing, fresh Bread, just try freezing the amount you need, before Cubing it. then Toast a few minutes in a 350* oven and your in business. Clyde.

Gluten Free substitution

I had been making this delicious breakfast casserole for years, then my wife was diagnosed with Celiac's disease, therefore unable to eat my casserole any longer due to the bread base of this casserole. I got to thinking, how do I continue to make this delicious dish for my family without making my wife sick? The answer was substituting frozen shredded hash brown potatoes for the bread! Simply layer the bottom of pan with the shredded hash browns (a generous layer), then put the potatoes in the oven for 15-20 minutes to partially cook them, then take them back out of the oven and continue the recipe as written and instructed above. This is a GREAT alternative to sliced (cubed) bread, and it may be just be a little bit better than using bread. So, all you Gluten free people out there, try this and I bet you'll like it, and it won't set off your gluten allergies. Enjoy!!!

Yummy breakfast casserole!

I have made this many times and it always is a family favorite! I also change out the meat for ham and even made the dish with shrimp as a mock dinner souffle for a potluck - every one always asks for the recipe.

Silly question! Dry mustard

Silly question! Dry mustard or yellow mustard?!

As easy to make as it is to enjoy. If you love cheese as much as I do, don't be afraid to add some more. The recipe makes more than enough for a small army. I served this dish with grits topped with hot butter. Enjoy! – Reviewed by Rick Richardson

I've used this recipe for my 6 daughters when they were growing up and for company. Everyone loved this. It's easy to make the night before. Pop it in the oven the next morning, makes a good hot breakfast. The kids thought it was a souffle. We have even added to the recipe over the years to make it our own. – Reviewed by Janna Price
