How to Make It
Heat a large pan of lightly salted water to boiling over high heat. Peel the asparagus stalks and trim the ends. Cut the stalks into 2-inch pieces.
Blanch the asparagus in the boiling water for 3 minutes or until bright green and crisp-tender when tested with a small knife. Remove with a slotted spoon and rinse under cold water to stop the cooking.
Add the spaghetti to the boiling water and cook according to the label directions until al dente. Drain.
Meanwhile, in a saucepan over medium-high heat, melt the butter. Whisk in the flour.
Add the broth and cook for 2 minutes, stirring constantly, until the sauce thickens. Blend in the goat cheese and lemon peel.
Toss the spaghetti with the asparagus, sauce, and half the Parmesan. Serve with pepper to taste and the remaining Parmesan.
