You can cook pasta in a crockpot but it's not the best way to cook pasta.
It's best to cook the pasta and then add it to the crockpot for best results as pasta can become too soggy when slow cooked in the crock pot.
However the pasta will cook and be edible even when cooked in a crock pot.
Uncooked pasta can be added to a crock pot or slow cooker to cook it.
But uncooked pasta can get soggy if not cooked first before it goes into the crock pot.
Uncooked pasta can be placed in a crock pot although it's best to cook the pasta first and then add it to the crock pot along with the other food so that it doesn't become soggy.
Adding the pasta uncooked to the crock pot will cause the pasta to become soggy but it's not gonna be harmful to do so.
I always precook the pasta on the stove and then mix it in with the food in the crock pot to keep it warm and add to the meal.
The last time I added some uncooked pasta to the crock pot the pasta cooked but it was too soggy when it did cook.
So I make the pasta first and then mix it in with the stuff in the slow cooker.
