Spread the uncooked egg noodles evenly in the bottom of the prepared casserole dish. Give the dish a little shake so the noodles lie in a fairly even layer; this helps them cook more evenly.
In a medium bowl, whisk together the condensed French onion soup and sour cream until smooth and well combined. The mixture will be fairly loose—that’s good,
