How to Tell if Rice-A-Roni is Bad

There are a few signs that indicate your Rice-A-Roni has gone bad and should be discarded:

  • Unpleasant sour or stale odor
  • Change in texture – very dry and crunchy, mushy, or slimy
  • Change in color – significantly duller or darker
  • Visible mold growth

Trust your senses – if Rice-A-Roni doesn’t look, smell or taste quite right, it’s best to play it safe and throw it out. Don’t taste test Rice-A-Roni that you suspect may be spoiled.

Shelf Life of Unopened Rice-A-Roni

An unopened box of Rice-A-Roni has an exceptionally long shelf life. Properly stored in a cool, dry pantry, Rice-A-Roni will stay fresh for 1-2 years past the “best by” date on the package.

The key factors affecting the shelf life of unopened Rice-A-Roni are the ingredients, packaging, and storage conditions:


Rice-A-Roni contains rice, pasta, seasonings, and dried vegetables. The main ingredients – rice and pasta – have a very long shelf life when dry. Seasonings also maintain quality and flavor for a long time when kept dry.


The box and inner pouches provide an airtight environment that protects the Rice-A-Roni from moisture, air, light, and pests. This prevents early spoilage and staleness.

Storage Conditions

Storing Rice-A-Roni unopened in a cool, dry pantry or cupboard is ideal. Consistent temperatures between 50-70°F and low humidity prevent premature drying out and extend shelf life. Avoid storage in hot, humid places.

So long as it was stored properly, unopened Rice-A-Roni that is past its “best by” date but still within 1-2 years may still smell and taste normal. Use your judgment, but it should be fine to eat.

Shelf Life of Opened Rice-A-Roni

Once opened, the shelf life of Rice-A-Roni is reduced due to exposure to air and moisture, but it will still last for a reasonably long time.

Here’s how long Rice-A-Roni can be expected to stay fresh after opening:

Pantry or Cupboard

When stored in an airtight container in the pantry, opened Rice-A-Roni will stay good for 3-6 months. Keep it away from heat, light, and moisture to get the full shelf life.


An opened box of Rice-A-Roni will last about 6-9 months in the refrigerator. The cool temperature helps slow spoilage.
