Preparation
Preheat broiler to high or oven to 400°F.
Place a large pot of water over high heat and bring it up to a boil to cook the pasta. Once at a boil, add some salt and the pasta, and cook just shy of al dente, according to package directions.
While the pasta is cooking, heat a medium-size skillet over medium heat and add the butter. When the butter melts, add the flour and cook about a minute. Whisk in the milk, season with salt and ground black pepper, and bring up to a bubble. Turn the burner off and stir in the cheese in a figure-eight motion until it's all melted.
When the pasta is done, drain it well and combine with sauce. Pour into baking dish and place under the broiler in or the oven to brown the cheese and enjoy.
