Much like most processed people foods, pasta is definitely not something parrots encounter in the wild, to say the least. Therefore you want to give them pasta that has the least number of ingredients and NO salt or other additives or enrichments or preservatives.
Now, cooked or uncooked - in the cooked state, what ever they can digest is going to be easier to digest. IN the uncooked state it is going to be harder for them to absorb nutrients. Personally we only give Salty cooked pasta and even then it is only occasionally ( like 1-2X a month) and not much when we do, maybe one elbow macaroni amount, or similar.
He eats dinner with us, his hot meal of the day. We defrost and cook his chop for each meal, zapping it for 45 seconds or so in the microwave , so that any foods in it that are better for him when cooked, like carrots, are done. When I am done eating, I walk past his wet food feeding station and if there are any foods left on my plate that he can eat, I offer it to him, just a small amount - 1/4 or less of a teaspoon. That is when he might get some pasta, or chicken or a bean or other. Lots of times there is nothing!
