Asparagus and Leek Lemon Pasta is a family friendly recipe that you can have on the table in half an hour. This no frills weeknight dinner has simple, spring flavors and stays skinny with whole wheat pasta and a light cheese sauce.
Meanwhile, melt the butter in a small saucepan over medium heat. Add the leek and saute until aromatic and soft, about 4 minutes. Whisk in the flour until it disappears, about 1 minute. Add the milk, lemon zest, nutmeg, salt, and pepper and let simmer, whisking occasionally until thick, about 4 minutes. Add the cheeses, whisking until melted and the sauce is smooth.
