Step 1

Spray a 9x13 pan with non-stick spray.

Step 2

Remove the crusts from the bread and discard. Cut the remaining bread into cubes. Spread in baking dish.

Step 3

Cut the ham into cubes. Layer on top of the bread cubes.

Step 4

Layer the grated cheese on top of the ham.

Step 5

In a medium bowl, whisk together the eggs, milk, half n' half, salt, mustard powder, and dried parsley, until fully combined. Pour this evenly over the top of the cheese in baking pan. Cover pan with plastic wrap, and refrigerate overnight.

Step 6

On the day you are going to bake it, remove the pan from refrigerator and let it sit for about 30-40 minutes, to take the chill off the pan. Preheat your oven to 350 degrees.

Step 7

When ready, remove plastic wrap, and place in oven.

Step 8

Bake for 1 hour at 350 degrees (or until it is eggs are "set" in the middle of pan). **If you forget, and end up taking the dish straight from the refrigerator to the oven, remember to add another 25-30 minutes of baking time!

Step 9

When done baking, remove pan to wire rack. Let it cool for about 10 minutes, then cut it into pieces. This dish is at it's very best once it has cooled down a bit. Enjoy!
