Bring a pot of water to a boil, add fettuccine and cook as directed on package.

Meanwhile, add butter to a skillet. Turn heat to medium and melt butter.

Once butter has melted add flour. Stir with a whisk until the flour and butter have combined (it will be very thick) Continue stirring for about 30 seconds.

Add the milk (I use whole milk, but anything other than nonfat will work). Continue to whisk. With a ladle add 2 ladles of your boiling pasta water to the skillet (approximately 1/2 cup).

Add your minced garlic and chopped basil to the skillet. Stir until combined.

Turn the heat to low and stir occasionally until the pasta is cooked.

Add pasta to the sauce. Stir and then serve hot with basil garnish.
