In this article, we will delve into the process of freezing fresh escarole, discussing the benefits, preparation methods, and storage techniques to ensure you get the most out of this incredible vegetable.
Introduction to Escarole and Its Benefits
Before diving into the freezing process, it’s essential to understand the unique characteristics and benefits of escarole. Escarole is rich in vitamins A, C, and K, as well as minerals like potassium and iron. It is also low in calories and high in dietary fiber, making it a healthy addition to various meals. The bitter flavor of escarole is not only a delight to the taste buds but also offers potential health benefits, such as supporting digestive health and providing antioxidants.
Choosing the Right Escarole
To freeze escarole effectively, you need to start with fresh, high-quality leaves. When selecting escarole, look for crisp, dark green leaves with no signs of wilting or yellowing. The freshness of the escarole will directly impact its quality after freezing. It’s also important to note that younger, more tender leaves will generally freeze better than older, tougher ones.
Preparation for Freezing
Preparation is key when it comes to freezing escarole. The process involves several steps to ensure the escarole remains fresh and retains its nutritional value. Initially, wash the escarole thoroughly in cold water to remove any dirt or debris. Then, dry the leaves with a salad spinner or gently with a clean towel to remove excess moisture, which is crucial for preventing the growth of unwanted bacteria during the freezing process.
Blanching – A Crucial Step
Blanching is a critical step in the preparation process for freezing escarole. It involves briefly submerging the leaves in boiling water or steam to inactivate enzymes that could lead to a loss of flavor, texture, and color. For escarole, blanching times can vary, but generally, it ranges from 30 seconds to 2 minutes, depending on the desired texture and the method used (water or steam). After blanching, immediately plunge the escarole into an ice bath to stop the cooking process and preserve its color and nutrients.
Freezing Methods
There are several methods to freeze escarole, each with its own advantages. The choice of method depends on how you plan to use the frozen escarole in the future.
Whole Leaf Freezing
For recipes where you want to maintain the texture and appearance of whole escarole leaves, such as in salads or as a garnish, whole leaf freezing is suitable.

Removing as much air as possible from the bag before sealing is crucial to prevent freezer burn and preserve quality.
Chopped Freezing
If you plan to use escarole in cooked dishes like soups or stews, freezing it in chopped form can be more convenient. Chop the blanched and cooled escarole into desired sizes, press out as much air as possible from the freezer bag or airtight container, and then store it in the freezer. Chopped escarole can also be frozen in ice cube trays filled with water or broth, making it easy to add to recipes without thawing.
Pureed Freezing
For baby food, smoothies, or as an addition to sauces, freezing escarole in a pureed form is a great option. After blanching and cooling, blend the escarole with a little water or broth until you achieve the desired consistency. Then, pour the puree into ice cube trays or freezer-safe containers and store them in the freezer. This method is especially useful for retaining nutrients and making escarole a convenient ingredient to incorporate into daily meals.
Storage and Thawing
Proper storage is essential for maintaining the quality of frozen escarole. Label all containers or bags with the date and contents and store them in the freezer at 0°F (-18°C) or below. Frozen escarole can last for several months when stored correctly. When you’re ready to use it, simply thaw the frozen escarole in the refrigerator overnight, or thaw it quickly by submerging the container in cold water.
Using Frozen Escarole
Frozen escarole is versatile and can be used in a variety of dishes. It’s perfect for soups, stews, sautéed dishes, and even as a nutritious addition to pizzas and pasta dishes. Because the blanching process has already softened the leaves, frozen escarole can be added directly to cooked dishes without needing to thaw it first, although thawing can help in achieving the desired texture in some recipes.
Tips for Maximizing Nutritional Value
To maximize the nutritional value of your frozen escarole, use it within a few months of freezing, as vitamins and minerals can degrade over time. Also, consider adding frozen escarole to dishes towards the end of cooking time to preserve as many nutrients as possible, especially water-soluble vitamins like vitamin C and B vitamins.
