How long does spinach last?

The shelf life of raw spinach is relatively short. An unopened bag of spinach can last up to two weeks if properly stored. Unbagged spinach tends to last longer but the exact timeframe is hard to pinpoint.

Spinach may also have light yellow spots that don’t wash away that indicate herbicide burn or damage. In these cases, it’s best to err on the side of caution and get rid of all of the spinach or at least the leaves that have the spots on them.

Tips for Washing

If you have a bundle of spinach held together with a band or wire, leave it like this for the first step of washing.

  1. Take the spinach by the stems and dunk the top part (the leaves) in a large bowl of cold water (or you can use a clean sink basin).
  2. Shake the leaves around so dirt and sand shake loose into the water.
  3. Take the spinach out of the water and dab it on a paper towel.
  4. Dump the bowl or empty the sink and refill with fresh, cold water.
  5. Next, cut off the bulk of the stems and remove the wire or band.
  6. Add the loose spinach leaves back into the bowl or sink and mix them around with your hand to remove any remaining grit. Remaining dirt and sand should sink to the bottom.
  7. Lift the spinach out with your hand or a slotted spoon and pat it completely dry with paper towels, or use a salad spinner.

If you have a pre-cut bag of spinach follow steps 6-7.

Tips for Storing

Though spinach doesn’t last long, there are some tricks you can use to keep it fresher longer.

  1. When you’re picking your spinach at the store, make sure you get the freshest bundle or package you can. Stay away from spinach that already has signs of spoilage like dark spots or droopiness.
  2. Once you get it home, keep your spinach as dry as possible until you need to use it. The best place is a plastic bag in the vegetable drawer of your fridge.
  3. Keep pre-bagged spinach in its original packaging. This packaging has special gasses pumped into it to preserve the leaves longer.
  4. When you’re ready to use spinach, you should wash it beforehand. But, ideally, you should only wash what you plan to use at the time.
  5. After you wash your spinach, be sure to pat the leaves dry or use a salad spinner to remove excess moisture.
  6. Once the spinach is completely dry, you can pack it in an airtight container lined with paper towels. Make sure you use a clean container so there’s no cross-contamination.
  7. You can also store the spinach in your salad spinner with paper towels on the bottom.
  8. If you want to go the extra mile, add your spinach a layer at a time, with paper towels in between.

Tips for Freezing

It’s also possible to freeze spinach for use in smoothies or heated recipes like omelets. You don’t want to use frozen spinach for salads or sandwiches as it will no longer be crisp.

  1. Blanch your spinach in boiling water for no more than 30 seconds.
  2. Immediately transfer the spinach to an ice bath to stop the cooking.
  3. Let the spinach cool for about 2 minutes. (This process helps to preserve the color, taste, texture, and nutrient value in the leaves).
  4. Squeeze out any excess water and place the spinach in a plastic bag.
  5. Remove any excess air and then store in the freezer until you need it. You can bring the spinach back to room temperature before cooking it or throw it right in if you’re making a smoothie.

Frozen spinach can last up to 12 months, other wise it may develop .

While spinach is considered a health food, it can also be dangerous if not cleaned and properly handled. And that starts from the time it’s grown, picked, processed, and packaged.

If you can, choose spinach that’s gone through less processing and handling or you can even grow your own!

Though it is possible to get food poisoning from bad spinach, its benefits typically outweigh any health risks when properly cleaned and stored.
