Cooking pasta to the point and then drying it in a dehydrator works fine for me!

I then put a portion of the precooked and dried noodles in an 1 litre freezerbag, add e. g. dried vegetables, mushrooms, herbs and spices, sauce-powder and perhaps a piece of storable cheese. Then I ad boiling water, stir well, close the bag, put it in some insulation (fleece pullover, bag cozy) and wait 10-15 min.. Then I stir again and eat (long spoon...). The rehydrated pasta tasted and felt always like freshly cooked in my experiments.

Take care that you cook/dry small, "thin walled" pasta, for it will rehydrate easier.
