Indeed, it is possible to freeze spinach in order to enhance its longevity. When correctly frozen, spinach’s expiration date is lengthened due to the preservation of its taste and texture. This method of storing spinach in the freezer can result in a superior flavor over time, compared to storing it in the fridge for the same period.
Freezing spinach in its original packaging might not provide sufficient air protection, which can lead to freezer burn. Freezing it individually or in smaller serving sizes can better preserve its flavor and freshness. Freezing in smaller serving sizes is the best method for freshness and longevity, as it minimizes air exposure and prevents freezer burn.
How To Freeze Spinach Safely
- Whether you have brand new or leftover spinach, choose your storage method. We typically recommend airtight plastic/glass containers or sturdy freezer bags for long-term storage freshness.
- Transfer it to where you plan to keep it.
- Be sure to leave about 1-2 inches of headspace to allow for expansion. Don’t leave too much room though because best practice is to limit air exposure as much as possible when freezing food.
- Label your containers or freezer bags as ‘Frozen spinach’ with today’s date.
- Place the bags flat in the freezer so they freeze quickly. If you’re using containers instead, place them in the freezer upright. Once completely frozen, both the bags and containers can be stacked and/or positioned upright.
Defrosting Tips
When you’re ready to prepare the spinach you just froze, do not thaw it at room temperature. Read our guide on how to thaw spinach safely. Not only will it help you avoid foodborne illnesses, using the proper defrosting techniques keeps its texture & quality intact.
How Long Can You Freeze Spinach?
You can freeze spinach for up to 10-12 months as long as it’s frozen correctly. Freezing spinach slows down spoilage, extends expiry, and allows you to store it for an increased time but all frozen food expires eventually.
Freeze smaller spinach portions within 2-3 days of purchasing for optimal freshness. Store leftover spinach in an airtight container after it’s initially opened.
Removing & defrosting frozen spinach within 10-12 months of freezer storage helps to prevent freezer burn, off-flavoring, and food poisoning. Anything longer than that puts the food at risk of:
| Consequences | Description | Recommendation |
|---|---|---|
| Freezer Burn | Dehydration and oxidation due to air exposure | Use well-sealed containers or bags |
| Loss of Freshness | Flavor and texture degradation over time | Consume within recommended time frame |
| Food Poisoning | Potential bacterial growth if improperly stored or thawed | Follow safe defrosting practices |
