Can I Cook Beef Stroganoff In Advance?
Yes, you can cook beef stroganoff in advance. In fact, it is best to make it ahead of time and let it sit in the fridge overnight as the flavors will meld together and the sauce will thicken. Simply reheat it on the stove or in the microwave before serving. You may need to add a little bit of extra liquid to loosen the sauce as it can thicken even more upon sitting in the fridge.
