Tips & Notes

  • Noodles: we've only tested this recipe with truRoots Ancient Grain Elbow Pasta. It cooks quickly and will continue to cook when taken out of the oven. Be conscious of this as you check the noodles after 5 minutes. Everyone's oven is a little bit different, so watch out that your noodles don't turn to mush!
