Our mom used to make this for New Year's Day breakfast. It is really yummy and easy. The original recipe says to make it the night before, but my husband does not like the bread to be too soggy, so I make it the morning of. Either way, it is delicious.
12 slices of bread (cubed)
1 lb sharp cheddar cheese
3 cups milk
3/4 teaspoon salt
3/4 teaspoon dried mustard
In a greased casserole dish, alternate layers of cubed bread, milk mixture, and cheese.
Bake at 350 degrees for 45-60 minutes, until golden brown and bubbly.
