← Replies in One Pot Chicken Parmesan Pasta Recipe

If you didn't boil the pasta in the sauce (or at least finish cooking it in the sauce) then that's why the sauce isn't sticking like it should. If boiling the pasta in the sauce weirds you out too much, and you just can't bring yourself to do it (though you should try it; it's great), then you'll need to make modifications. First, you'll need to reserve at least a ladle-full of the water you cooked the pasta in and add it to the sauce. When pasta cooks, it releases starches into whatever it's boiled in, and those starches are what allows the sauce to bind to the pasta. Then, you must not rinse the pasta after straining it, and do not add oil to the pasta. Oil will keep the pasta from sticking to itself, but it will also keep the sauce from sticking to the pasta. If your noodles do stick together, they will stop sticking for the most part once you pour them all back in the sauce and give it a good mix. :) hope this helps

I came here to say exactly what the person who replied before me said, lol. The water that's added in with the sauce, before the chicken and pasta are added back, is meant to be the extra liquid that cooks the pasta, so that also might have been an issue with the sauce not sticking, as well.
