How to keep pasta without sauce warm?
Remove the pasta from its cooking liquid with a pasta fork into a colander. Wrap with foil to keep the pasta over the hot water. As you need it, just pull foil aside and take what you need. Of course, if you have a pasta pot, just tilt the cooking insert over the water and wrap as above. This should help. If you want to try a different way, you can pour some olive oil into a covered casserole dish. Spoon pasta and some water into it and cover. Leave in oven set at very low temp to keep pasta warm. Enjoy!
