My first ever attempt at homemade pasta was with plain pasta. There is nothing basic when it comes to fresh pasta. It has such a special bite compared to the usual dried packaged pasta. Plain pasta gives you the opportunity to do whatever sauce you want from pesto to tomato to browned butter.
So often when I roast a batch of beets, I end up with more than what I need. They are easy to puree and incorporate into pasta. If you are looking for a shortcut, you can even use packaged roasted beets.
