Bob Evans mashed potatoes in a refrigerator-safe bowl or airtight container usually last about 7 days after opening , as long as they were refrigerated promptly and kept cold the whole time. If they were left in the fridge in the original opened tub or transferred to a clean sealed bowl, the same 7-day window is the safest rule of thumb.

Fridge timing

  • Opened and refrigerated: about 7 days.
  • Unopened: follow the package “use by” date.
  • If you’re unsure: toss them sooner if they smell sour, look watery, or have any mold.

Storage tips

  • Put them in an airtight container or tightly covered bowl.
  • Keep the fridge at or below 40 F.
  • Don’t leave them out for long before putting them back in the fridge.

Quick check

If they were in a “Loc and Snap” bowl and that bowl sealed well, storage time is usually the same as any other covered container: roughly 7 days after opening.

If you want the safest answer for a specific tub or date opened, tell me when it was opened and whether it’s been reheated already.
