I have also successfully made this recipe with dried fettuccine pasta. Depending on the brand of fettuccine, you will likely need to add an additional 1 - 2 minutes onto the cook time listed in the recipe. To compensate for the added cook time, you may also need to add in about 1/4 - 1/3 cup extra liquid toward the end of the cook time (either water or milk) to prevent the pan from getting too dry before the pasta is done cooking. Substituting dried fettuccine works here because fettuccine and linguine have similar cook times. I don't recommend trying to use a pasta that takes much longer or shorter to cook, because you will end up with either too much or not enough liquid in the final dish.
