Learn how to freeze spinach for later use with these easy tips and tricks. Discover the best methods for freezing and storing spinach to keep it fresh and delicious.

Benefits of Freezing Spinach

Longer Shelf Life

Freezing spinach is an excellent way to extend its shelf life. Fresh spinach has a short shelf life and can only be stored in the refrigerator for up to five days. When you freeze spinach, you can keep it for up to eight months, which means you can enjoy fresh-tasting spinach all year round. It's essential to blanch the spinach before freezing it to preserve its quality and nutrients. Blanching helps to stop the enzyme activity that can lead to spoilage, discoloration, and nutrient loss.


Freezing spinach is an excellent way to have this healthy green on hand whenever you need it. Frozen spinach is perfect for adding to smoothies, soups, stews, pasta sauces, dips, and more. Since frozen spinach is already cooked, you can easily add it to any recipe without the need for extra preparation time. Plus, frozen spinach takes up less space in your refrigerator, leaving more room for other fresh produce.

Cost Savings

Another benefit of freezing spinach is cost savings. Fresh spinach can be expensive, and buying it every week can add up quickly. When you freeze spinach, you can buy it in bulk when it's on sale or in season, and save money in the long run. You also reduce food waste by freezing spinach that you may not be able to use up before it spoils.

How to Freeze Processed Spinach

Blanching Spinach

Blanching is an essential step before freezing spinach. It involves boiling the spinach briefly to stop the enzymatic reactions that can cause the spinach to spoil quickly. To start, wash the spinach thoroughly in cold water and remove any tough stems. Bring a pot of water to a boil and add the spinach, making sure it is fully submerged. Boil for 1-2 minutes, then remove it and place it immediately in a bowl of ice water.

Shocking Spinach

Shocking the spinach in ice water immediately after blanching is crucial to stop the cooking process and prevent the spinach from becoming mushy. This step also helps to retain the spinach's vibrant green color. Once the spinach has cooled down, remove it from the ice water and drain it thoroughly using a colander or paper towels.

Freezing Spinach in Bags or Containers

After blanching and shocking, you can now freeze your processed spinach. The best way to freeze spinach is by using freezer bags or containers. Pack your spinach into quart-sized freezer bags, making sure to remove as much air as possible before sealing. You can also use small containers with lids, but make sure they are freezer-safe and leave enough headspace for expansion.

Label your bags or containers with the date and contents, then place them in the freezer. Frozen spinach can last for up to eight months in the freezer. When you are ready to use it, simply thaw it in the refrigerator overnight or on the countertop for a few hours.

Preparing Spinach for Freezing

Cleaning Spinach

The first step in preparing spinach for freezing is cleaning it thoroughly. Start by removing any yellow or wilted leaves, as well as any thick stems. Then, rinse the spinach under cold running water to remove any dirt or debris. If the spinach is particularly dirty, you may need to repeat this step several times until the water runs clear.

Drying Spinach

After cleaning the spinach, it's important to dry it thoroughly before freezing. Excess water can cause ice crystals to form, which can damage the texture and flavor of the spinach. To dry the spinach, place it in a salad spinner or wrap it in a clean kitchen towel and gently press out any remaining water.

Chopping or Pureeing Spinach

Once the spinach is clean and dry, you can either chop it into small pieces or puree it in a blender or food processor. Chopping the spinach will allow you to use it in recipes where you want small pieces of greens, such as quiches or omelets. Pureeing the spinach will give you a smooth consistency that is ideal for adding to sauces, soups, and smoothies.

To chop the spinach, simply lay it on a cutting board and use a sharp knife to cut it into small pieces. Alternatively, you can use kitchen shears to snip the spinach into small pieces directly over your cooking pot or mixing bowl.

To puree the spinach, add it to a blender or food processor along with a small amount of water or vegetable broth. Blend until smooth, then pour the puree into freezer-safe containers.

By following these simple steps for cleaning, drying, and chopping or pureeing your spinach, you'll be able to enjoy fresh-tasting greens all year long. Whether you're using them in soups, sauces, or smoothies, frozen spinach is a versatile ingredient that will add nutrition and flavor to your favorite recipes.

How to Store Spinach Optimally

Freezing Spinach in Portions

Freezing spinach is an excellent way to preserve its nutrients and freshness. However, freezing it in bulk may lead to waste as you may not use it all at once. Therefore, freezing spinach in portions is an ideal way to store it optimally. First, ensure that you wash and blanch the spinach before freezing it. Blanching helps to retain the color and texture of the spinach. After blanching, squeeze out any excess water and pack the spinach into portions. Use freezer bags or containers to store the portions separately.

Labeling Spinach with Dates

Labeling the spinach with dates is crucial to keep track of when you stored it in the freezer. This will help you keep a check on how long the spinach has been stored, and you can use it accordingly. Always use a permanent marker to label your freezer bags or containers, indicating the date of storage. This way, you can ensure that you use up the spinach within the recommended time frame.

Storing Spinach in the Freezer

Storing spinach in the freezer requires some careful planning. Ensure that you store the spinach in a part of the freezer that is not prone to temperature fluctuations. Storing spinach in a self-defrosting freezer is not recommended as it may cause freezer burn. Freezer burn can cause discoloration and loss of nutrients in your spinach. Therefore, always use a deep freeze to store your frozen spinach.

Storing Spinach for Maximum Freshness

How to Thaw Frozen Spinach

Thawing Spinach in the Fridge

One of the safest ways to thaw frozen spinach is in the fridge. This method allows the spinach to defrost slowly, maintaining its texture and flavor. To do this, remove the frozen spinach from the freezer and place it in the fridge for about 24 hours. Make sure to put the spinach in a bowl or on a plate to catch any water that may be released as it thaws. Once fully defrosted, you can use it right away or store it in an airtight container in the fridge for up to three days.

Thawing Spinach in Cold Water

If you need to defrost spinach quickly, you can use the cold water method. This method is faster than thawing in the fridge but requires a bit more attention. To do this, place the frozen spinach in a sealed plastic bag and submerge it in a bowl of cold water. Change the water every 30 minutes until the spinach is fully defrosted, which should take about an hour. Once defrosted, remove the spinach from the bag and drain off any excess water before using it.

It's important to note that you should never thaw spinach using hot water or a microwave. These methods can cause the spinach to cook or become mushy, which will ruin its texture and flavor.

How to Use Frozen Spinach

Adding Frozen Spinach to Soups, Stews, and Sauces

One of the easiest ways to use frozen spinach is to add it to soups, stews, and sauces. Frozen spinach is already cooked and chopped, which makes it a convenient ingredient to add to any dish. To use frozen spinach in soups and stews, simply add it directly to the pot during the last few minutes of cooking. For sauces, thaw the spinach first, then squeeze out any excess water before adding it to the sauce.

Using Thawed Spinach in Casseroles and Quiches

Thawed spinach is perfect for casseroles and quiches. To use thawed spinach in a casserole or quiche, first thaw the spinach in the refrigerator overnight. Then squeeze out any excess water before adding it to the dish. Thawed spinach can also be used as a filling for lasagna or stuffed shells.

When using frozen spinach in recipes, keep in mind that it can be salty. Some frozen spinach products are blanched in salt water before freezing, which can result in a salty taste. To avoid this, look for frozen spinach that has not been blanched or that has been blanched in water only.

Overall, freezing spinach is a great way to preserve this nutritious vegetable for future use. By using frozen spinach in soups, stews, sauces, casseroles, and quiches, you can enjoy its health benefits year-round. Just remember to thaw the spinach before using it and to be mindful of its salt content. With these tips in mind, even beginning gardeners can make the most of their spinach harvests.

Tips for Quality Frozen Spinach

Choosing the Right Spinach

When it comes to freezing spinach, it is essential to choose the right kind of spinach. The best spinach for freezing is the baby spinach or the fully grown spinach leaves that are fresh and free of any blemishes. If you have a garden, then you can harvest your spinach early in the morning when it is still fresh and healthy. Avoid using overripe or wilted spinach, as this will not freeze well.

Avoiding Freezer Burn

Freezer burn is a common issue when it comes to freezing vegetables, including spinach. Freezer burn occurs when moisture evaporates from the surface of the spinach, causing it to become dry and discolored. To avoid freezer burn, you need to properly store your spinach. Start by placing your spinach in a plastic bag and removing as much air as possible before sealing it. Then, place the bag of spinach in an airtight container or another plastic bag and label it with the date of freezing.

Using Frozen Spinach Within 6 Months

It is essential to use your frozen spinach within six months to ensure it remains fresh and safe for consumption. After six months, frozen spinach may start to lose its quality and texture, affecting its flavor and nutritional value. When you are ready to use your frozen spinach, remove it from the freezer and thaw it in the refrigerator overnight. After thawing, drain any excess water and use it as you would fresh spinach.

Final Tips for Freezing and Storing Spinach

Avoiding Overpacking Spinach

When freezing spinach, it is important to avoid overpacking the freezer bags or containers. Overpacking can cause the spinach to freeze together in clumps, making it difficult to separate and use later on. Instead, pack the spinach loosely in the container or bag, leaving some room for air to circulate. This will ensure that the spinach freezes evenly and can be easily portioned out when needed.

Freezing Spinach with Other Vegetables

If you have other vegetables that you want to freeze along with your spinach, it is best to blanch them first before freezing. Blanching involves briefly boiling the vegetables and then quickly cooling them in ice water. This helps to preserve their flavor, color, and texture during the freezing process. Once the vegetables are blanched and cooled, mix them together with the spinach and pack them in freezer bags or containers.

Using Frozen Spinach in Smoothies and Juices

Frozen spinach is a great addition to smoothies and juices as it adds a boost of nutrition without altering the flavor too much. To use frozen spinach in your smoothies or juices, simply remove a portion from the freezer bag or container and add it to your blender or juicer. It is not necessary to thaw the spinach beforehand as it will blend up easily when frozen.
