Sartori MontAmore Mac and Cheese

1 block Sartori® MontAmoré Cheddar, shredded
1 wedge Sartori® Classic Fontina, shredded
1 wedge Sartori® Classic Parmesan, grated
4 cups dried macaroni
1 egg, beaten
6 tablespoons butter
1/4 cup all-purpose flour
2 1/2 cups milk
2 teaspoons dry mustard
1/4 cup Panko breadcrumbs
1/3 cup fresh parsley, chopped
Salt & pepper, to taste

Bring a large pot of salted water to a boil. Cook pasta for a few minutes (it should be too firm to eat) and drain.

Melt 4 T. butter in a large pot. Sprinkle in flour and whisk over medium-low heat until golden brown (3-5 mins.).

Whisk in milk and mustard until smooth and cook until the mixture thickens (3-5 mins.). Reduce heat to low.

Temper the egg by slowly whisking in 1/4 cup of the warm sauce. Whisk tempered egg mixture into sauce. Stir in all cheese except for 1/2 cup Parmesan. Season to taste.

Pour into a baking dish. Melt 2 T. butter and combine with breadcrumbs and parsley. Sprinkle over dish and bake at 350°F until golden brown & delicious — about 15 mins.
