This creamy spinach artichoke pasta has all the flavors you love in spinach artichoke dip in a sauce for pasta! Fettuccine stands up nicely with this rich sauce, but rotini or farfalle would work, too. Be sure and keep some of the pasta cooking water in case you prefer a thinner sauce. It’s optional, but fresh herbs, such as parsley, thyme, or snipped chives make a nice garnish.
