Homemade Chicken and Noodles in Crockpot?

If I understand your question correctly, you are asking if it would be ok to pre-cook your chicken, pre-cook your noodles, and then put them together in the crock-pot to keep warm until serving time. Yes, that's the way I would do it. You might need to stir every once in a while to make sure they're not sticking. I would go ahead and cook the noodles in the bouillon water. I'm not sure how much of the noodles or chicken you are preparing, but I would start with a couple of cups of water or the broth you cooked your chicken in. If you are using left-over chicken, use one bouillon cube to each cup of water and then one extra cube for the taste. Sounds yummy!
