How long does Alfredo pasta last in the fridge?

Alfredo pasta can last for 3-5 days in the fridge. If stored properly, it can last for a week in the fridge. In the freezer, the shelf-life would extend to 1-2 months.

How to store Alfredo pasta?

  • Alfredo pasta should be refrigerated within two hours of it being cooked. If you are planning to refrigerate the leftovers of Alfredo pasta, do so in an airtight container and then place them in the fridge. You can also place them in resealable plastic bags too.
  • Avoid placing Alfredo pasta for more than 2 hours at room temperature. This is because bacteria can easily spoil the pasta and grows at temperatures ranging between 40℉ and 140℉.

If the temperature of your kitchen is especially warm or more than seventy degrees, you cannot keep your Alfredo pasta outside for long.

  • As mentioned before, store the pasta in the fridge below the temperature of 40℉.
  • If you are planning to place the pasta in the freezer, do so in heavy-duty freezer bags. Freeze the pasta at 0℉.
  • If you wish to thaw the pasta, you can place it in the fridge overnight or heat them in a microwave. If you wish to thaw them in a microwave or cold water, make sure to consume them immediately.
  • If you are planning to reheat pasta, do it only once. Reheating the pasta, again and again, can spoil the texture of the pasta. It might also not kill all the pathogens effectively too.
  • If you are planning to freeze pasta do it so along with the sauce (here, it is Alfredo sauce). Storing the pasta alone can make it mushy and spoil its texture.
  • It would be better to check the temperature of the fridge using a thermometer. This can help you in keeping an eye on the fridge’s thermostat.

How to detect spoilt Alfredo pasta?

  • If the pasta has been uncooked, you would notice a mushy or slimy appearance to it. This is an indication of the pasta spoiling.
  • Mold formation is another sign of spoilage. If you observe a whitish or grayish discoloration, it is a sign of mold growth. Sliminess usually precedes mold formation.
  • You can also smell the pasta to detect discoloration. If the pasta has a rotten odor, it is better to avoid consuming it.
  • If you do not observe any signs of spoilage and cannot smell any odor coming out of the pasta. Taste it. If it tastes, fine consume it or else discard them.

When you freeze Alfredo pasta, it is difficult to determine using your eyes or nose whether the pasta has gone rancid. Sometimes you might be able to detect a foul odor.
