How long past best by date for knorr past sides?

Knorr Pasta Sides can typically be consumed up to 1-2 years past their "best by" date if they have been stored properly and show no signs of spoilage, such as unusual odors or discoloration. However, the best by date indicates peak quality, so while they may still be safe to eat, the flavor and texture might not be as good. Always use your judgment and check for any signs of deterioration before consumption.
