Spread the softened butter across the bottom and sides of a 9x13 casserole dish.
1 tablespoon butter
Cube your bread (about 1-1.5 inches). Place the bread in the prepared 9x13 dish.**If your bread has a thick or tough crust remove that and discard, only using the inside, soft parts of the bread.
4 cups French bread
Add your cubed ham on top of the bread cubes, then sprinkle on the cheese.
2 ½ cups (up to 3 cups) cooked ham, 1 ½ cups cheddar cheese
In a bowl whisk together eggs, milk, mustard, and seasonings.
8 large eggs, 2 cups whole milk, 2 teaspoon dijon mustard, ½ teaspoon each - Lawry's Seasoned Salt, onion powder & garlic powder
Pour the egg mixture evenly over top of the bread/ham/cheese. Cover and refrigerate over night (12-24 hours). Can be made 2 days in advance.
Baking
Preheat the oven to 375°. Meanwhile, uncover the casserole and set on the counter.
Once the oven is fully heated, bake uncovered for 45 minutes.
Let the casserole rest for about 10-15 minutes before slicing.
Bread - this recipe is a great way to use up day old bread. I call for "French bread" however you can use what you have. If you have sourdough, use it. If you have leftover rolls, use them. I have made this with leftover slider buns, and it worked great! Ham - if using leftover ham you will need about 2 ½-3 cups. If you are purchasing a ham steak grab one that is about 1- 1.25 lbs. That gives you enough meat after you have trimmed the bone and the fat.
