In a medium bowl, combine the eggs, milk, butter, cheddar cheese, and onion, salt, pepper, and onion powder. Pour egg mixture on top of ham and bread. (Be sure to gently incorporate the melted butter. If it’s too hot it will curtle the eggs.)
8 eggs, 3 cups milk, ¼ cup butter, 2 cups cheddar cheese, ½ onion, ½ tsp Salt, ½ tsp pepper, 1 tsp onion powder
