I LOVE Mac 'n Cheese. Always have and I probably always will.

Baked Mac 'n Cheese
2 cups dried elbow macaroni (4 cups cooked)
1/3 cup grated Cheddar Cheese
1/3 cup grated Swiss Cheese
1/3 cup grated Jack Cheese
1/3 cup grated Colby Cheese
1/3 cup grated Muenster Cheese
1/3 cup grated Parmesan Cheese
1/2 cup sour cream
4 tablespoons butter, cut into pieces
3 eggs
1/2 teaspoon salt
1/2 teaspoon pepper
1 cup milk
Nonstick spray

Topping:
1 cup bread crumbs
1 teaspoon paprika
1/4 cup butter, melted
1/4 cup grated Parmesan
--------
Preheat oven to 350°.

In a large pot, bring water to boil. Season water with salt and cook macaroni until al dente, about 10 minutes. Drain pasta and place in a large bowl and while pasta is still hot add all the cheese. In a separate medium bowl, using a whisk, combine the sour cream, butter, eggs, salt, pepper, and milk and add to the macaroni mixture. Spray casserole dish with nonstick and pour macaroni mixture into the dish.

For the topping, in a small bowl, mix the bread crumbs with the paprika, butter, and the Parmesan. Sprinkle the bread crumb mixture over the macaroni and bake until golden brown and bubbly, about 30-45 minutes
Top with additional cheese, if desired
