What You Need
1 pound dry shell or elbow pasta
kosher salt
4 tablespoons butter
1/4 cup AP flour
1 cups whole milk
1 cup heavy cream (or half & half)
1 1/2 teaspoon Dijon mustard
3/4 pound sharp white cheddar, shredded
1/4 pound white American cheese
What To Do
Boil a large pot of water and season with 2 tablespoons of kosher salt. Add the pasta and cook until it reaches al dente, don’t overcook the pasta. Drain it and set aside.
Melt the butter in a saucepan over medium heat, then add the flour and whisk until you form a smooth and thick paste. Make sure there are no lumps, and then cook for about 2 minutes until it has become fragrant but not brown.
Lower the heat to medium-low and add in the cream, milk, mustard, and a teaspoon of salt. Whisk continuously until the sauce bubbles and becomes thicker, which should take about 5 minutes or so.
Add in the cheese and mix with a wooden spoon until it has all melted. Toss in the cooked pasta and mix until it is all evenly coated.
