Macaroni and Cheese Casserole

1 pound elbow macaroni pasta
3 tablespoons butter
1 cup shredded Swiss cheese
1 cup grated parmesan cheese plus 2 tablespoons
2 cups sharp Cheddar cheese
1/2 teaspoon salt
1 cup heavy cream
1 egg
1/4 cup milk

Preheat oven to 350 degrees. Butter a 9-by-13 pan or casserole dish and set aside.

Bring a large pot of water to a boil. Add pasta and cook 5-8 minutes or until pasta is tender. Turn off heat and remove pasta from the stove.

Drain pasta in a colander and then return to pot while still hot, dotting with butter cut up into smaller pieces.

Slowly sprinkle the cheeses (reserving 2 tablespoons of the Parmesan) onto the hot pasta, turning noodles with a wooden spoon to spread cheese evenly. Add salt and stir gently so as not to break up noodles. Set aside.

Pour heavy cream into a microwave-safe measuring cup and warm in microwave, about 30 seconds. Add egg and milk to cream and whisk with a fork. Pour cream mixture over pasta, stirring again to incorporate. Pour pasta mixture into dish, sprinkle the top with the remaining 2 tablespoons of parmesan and bake about 20 minutes or until cooked through and cheese is lightly browned on top. Serve warm.
