I haven’t tried it with this particular recipe, but I don’t think the linguine will hold up very well under the long cook time. If you want to try it, cook the rest of the ingredients in the crockpot first, then add the noodles during the last hour or so of cook time. Or, cook them separately on the stove and mix together your cheesy chicken pasta just before serving. Just know that the flavor won’t be as rich since it isn't cooked together with everything else.
