What is your biggest cooking stuff up?(both)

I was the host of an upcoming Winter dinner meal for 6.
Pumpkin Soup
Beef Stroganoff
Wine Trifle

Made Soup and Trifle ahead of time but wanted the Stroganoff Completed an hour before Guests arrived.
Big Mistake
Had never cooked this dish before and made the mistake of putting to much of the Meat into pan at once.
It became a gluggy mess. Total Failure
Luckily I had Pasta and Some bacon.
Knocked up Pasta Carbonara by Precooking Pasta.
Carbonara is one of the easiest and quickest meals to cook
