Can gravy that was made from mix sit out overnight and still be good next day?

It's not recommended to leave gravy made from mix out overnight. Here's why:

* Spoilage: Gravy, especially if made with a mix, contains ingredients that can spoil quickly at room temperature. Bacteria can grow rapidly, potentially making you sick.

* Texture: Gravy can become thick and clumpy overnight, making it less palatable.

* Flavor: The flavor of the gravy can also degrade, losing its freshness and becoming dull.

Instead, consider these options:

* Refrigerate immediately: Store the gravy in an airtight container in the refrigerator for up to 3-4 days.

* Freeze for longer storage: You can also freeze gravy for up to 2 months. Thaw it in the refrigerator overnight before reheating.

Always err on the side of caution when it comes to food safety. If you're unsure about the safety of leftover gravy, it's better to discard it.
