Ingredients

6 cups cubed gluten-free white bread (like our Vegan Oat Bread, 1” cubes)

2 cups shredded sharp cheddar cheese
5 eggs
2 cups milk
½ tsp ground mustard
½ tsp salt
½ tsp pepper
½ tsp garlic powder

Instructions

Lightly grease a 9×13 Pyrex glass baking dish.
Mix cubed white bread and cubed ham in the baking dish and sprinkle with shredded cheese.
In a bowl, beat the eggs, then mix in the milk, dry mustard, salt, pepper, and garlic powder. Pour it over the ham and bread mixture.
Pour it over the ham and bread mixture, and then pour the melted butter on top.
Cover and refrigerate overnight.
In the morning, remove the casserole from the fridge and uncover. Let sit at room temperature while the oven preheats to 325°F.
Once the oven is preheated, place the uncovered casserole in the oven and bake at 325°F for an hour.
Once cooked, remove from the oven and let cool for 5 minutes before serving.
