Properly selecting and preparing escarole is crucial for successful freezing. This process ensures the best flavor, texture, and nutritional value are preserved.

Choosing Fresh Escarole

Select escarole heads with crisp, vibrant green leaves. Avoid any with yellowing, wilting, or brown spots. The outer leaves should be firm and free from blemishes.

Look for compact heads with tightly packed centers. Smaller heads tend to be more tender and less bitter.

Check the cut ends – they should appear fresh and not dried out. Avoid escarole with slimy or mushy stems.

For best results, use escarole within 3-5 days of purchase. Store it in the refrigerator wrapped loosely in plastic until ready to prepare for freezing.

Cleaning and Prep Work

Thoroughly rinse escarole leaves under cool running water. Remove any dirt, debris, or insects.

Trim off the tough base of the head and discard any damaged outer leaves.

Separate the leaves and inspect them individually. Cut out any bruised or discolored portions.

Pat the leaves dry with clean kitchen towels or use a salad spinner to remove excess moisture.

Cut or tear the leaves into bite-sized pieces suitable for your intended use in soups or sautés.

Reducing Bitter Taste

Escarole can have a slightly bitter flavor, especially in the darker outer leaves.

To reduce bitterness, soak the prepared leaves in cold water for 15-30 minutes. This helps draw out some of the bitter compounds.

For a stronger effect, add a pinch of salt or a splash of vinegar to the soaking water.

After soaking, rinse the leaves again and dry thoroughly before freezing.

Blanching the escarole briefly in boiling water can also help mellow the flavor. Plunge the leaves into ice water immediately after blanching to stop the cooking process.

Blanching Escarole

Blanching is a crucial step in preparing escarole for freezing. This process preserves the vegetable’s color, flavor, and nutritional value while also reducing its natural bitterness.

Blanching Process Overview

To blanch escarole, start by thoroughly washing the leaves under cold running water. Remove any dirt or debris and trim off tough stem ends. Fill a large pot with water and bring it to a rolling boil. Add a pinch of salt to enhance flavor.

Prepare an ice bath in a separate bowl while the water heats up. This will be used to quickly cool the escarole after blanching, halting the cooking process.

Once the water is boiling, submerge the escarole leaves. Use tongs or a slotted spoon to ensure all leaves are fully immersed in the hot water.

Blanching Times and Techniques

Blanch escarole for 1-2 minutes. Timing is critical – underblanching won’t deactivate enzymes, while overblanching can lead to loss of flavor, color, and nutrients.

After the blanching time is up, quickly transfer the escarole to the prepared ice bath. This rapid cooling stops the cooking process and helps maintain the vegetable’s crisp texture.

Once cooled, drain the escarole thoroughly. Pat the leaves dry with clean kitchen towels or use a salad spinner to remove excess water. Proper drying prevents ice crystals from forming during freezing.

For best results, freeze blanched escarole within two hours of processing. This ensures maximum freshness and quality when you’re ready to use it in soups or sautés.

Packing and Storage

Pre-freezing escarole is essential for maintaining its quality. Spread clean, dry leaves on a baking sheet lined with wax paper. Place the sheet in the freezer for 1-2 hours until the leaves are firm. This prevents clumping during long-term storage.

Transfer the pre-frozen escarole to freezer-safe bags or containers. Remove as much air as possible to prevent freezer burn. Label each package with the date and contents. Store the escarole in the freezer at 0°F (-18°C) or below.

Frozen escarole can last up to 6 months when properly stored. For best results, use within 3-4 months to ensure optimal flavor and texture.

Vacuum Sealing for Longevity

Vacuum sealing offers superior protection for frozen escarole. This method removes all air from the packaging, significantly reducing the risk of freezer burn and extending shelf life.

To vacuum seal escarole, place pre-frozen leaves in a vacuum-seal bag. Use a vacuum sealer to remove the air and seal the bag. Vacuum-sealed escarole can maintain quality for up to 12 months in the freezer.

For added convenience, portion the escarole before sealing. This allows for easy use of smaller amounts without thawing the entire batch. Label each vacuum-sealed package with the contents and date for easy identification.

Thawing and Using Frozen Escarole

To thaw frozen escarole, transfer it from the freezer to the refrigerator and let it defrost slowly overnight. This method helps preserve the texture and nutrients. Avoid thawing at room temperature, as it can lead to bacterial growth.

For quicker thawing, place the sealed bag of frozen escarole in a bowl of cold water. Change the water every 30 minutes until the leaves are pliable. Pat dry with paper towels before use.

Microwave thawing is possible but requires caution. Use the defrost setting and check frequently to prevent cooking. Once thawed, use the escarole immediately for best results.

Cooking with Thawed Escarole

Thawed escarole works well in cooked dishes like soups and sautés. For Italian wedding soup, add the thawed escarole directly to the simmering broth. It will cook quickly and absorb the flavors of the soup.

To sauté, heat olive oil in a pan, add minced garlic, and cook the thawed escarole until wilted. Season with salt, pepper, and a splash of lemon juice for a simple side dish.

Escarole and bean soup is another excellent option. Combine thawed escarole with cannellini beans, broth, and aromatics for a hearty meal. Simmer until the escarole is tender.

Alternative Uses for Frozen Escarole

While best suited for cooked dishes, thawed escarole can be used in cold applications. Chop it finely and add to salads for a slightly different texture. Mix with other greens to create a unique salad blend.

Use thawed escarole as a pizza topping. Spread it over the cheese before baking for a crispy, slightly bitter addition to your pie.

Blend thawed escarole into green smoothies for a nutrient boost. Combine with fruits like apples or pears to balance the flavor.
