• 5 T. unsalted butter
• 1/2 cup all-purpose flour
• 4 cups warmed whole milk (I usually add a bit more to keep it creamier rather than thicker)
• Pinch fresh nutmeg
• Sea salt and white pepper
• 1 cup grated fontina
• 1/2 pound thinly sliced prosciutto, julienned
• 1 pound dry rigatoni
• 3 tablespoons unsalted butter, diced

1. Preheat oven to 425 degrees F.
3. In a 2 quart saucepan, melt the butter over medium heat. Add the flour and whisk until smooth, about 2 minutes. Always stirring, gradually add the milk and continue to whisk until the sauce is smooth and creamy. Simmer until it is thick enough to coat the back of a spoon. This will take approximately 10 minutes. Remove from heat and stir in nutmeg, ½ cup fontina, prosciutto and season with salt and white pepper. Set aside.
4. In a large pot, bring to a boil 6 quarts of salted water. Add the rigatoni and cook for about 5 minutes. Since you will be cooking the pasta a second time in the oven, you want to make sure the inside is still hard. Drain in a colander. Return pasta to the pot and pour in bechamel sauce. Using a wooden spoon, mix well until all the pasta is coated with the sauce.
5. Into a greased 13 by 9-inch baking dish, pour the pasta with cream sauce. Smooth out top and sprinkle with remaining 1/2 cup fontina. Dot the top with diced butter and bake in oven for 25 minutes or until bubbling and the top is golden brown.

I call this my Mac 'N Cheese as it has taken the place of the house's favorite staple meal - it truthfully belongs to Giada de Laurentiis...God love her! To mix it up from time to time, I add diced veggies & omit the prosciutto. It's a rich meal as a main, so I recommend it as a side...but there won't be leftovers...trust me!
