You can either dry, freeze or refrigerate your homemade fettuccine. For long-term storage, drying or freezing your homemade pasta is the best option to extend its shelf life. To dry your pasta, add flour so the strands don't stick together. Hang noodles on a pasta drying rack, or lay on a cookie sheet. Dry the pasta for 12-24 hours, checking every few hours for progress. Once the pasta snaps when twisted, it's ready to be stored in an airtight container.
