What is Escarole and Why Should I Freeze It?
Escarole is a type of leafy green vegetable that belongs to the endive family. It is a nutrient-rich food that is high in vitamins A, C, and K, as well as minerals like potassium and iron. Freezing escarole is a great way to preserve its nutritional value and flavor, especially when it’s in season and abundant. By freezing it, you can enjoy escarole year-round and add it to a variety of dishes, from soups and stews to salads and sautéed side dishes.
Freezing escarole also helps to preserve its delicate flavor and texture. When fresh escarole is not stored properly, it can quickly become bitter and develop an unpleasant texture. Freezing it helps to lock in its natural sweetness and crunchy texture, making it a great addition to many recipes. Additionally, frozen escarole is just as nutritious as fresh escarole, so you can feel good about enjoying it even when it’s out of season.
How Do I Prepare Escarole for Freezing?
To prepare escarole for freezing, start by washing it thoroughly in cold water to remove any dirt or debris. Remove the tough outer leaves and trim the stems to about an inch from the base of the plant. Blanch the escarole in boiling water for 2-3 minutes to inactivate the enzymes that can cause spoilage and preserve its color and texture. Immediately submerge the blanched escarole in an ice bath to stop the cooking process.
After blanching and cooling the escarole, remove it from the ice bath and gently squeeze out as much water as possible. You can use a salad spinner or a clean kitchen towel to remove excess moisture.

Once the escarole is frozen solid, transfer it to airtight containers or freezer bags for long-term storage. This method helps to preserve the texture and flavor of the escarole and prevents it from becoming a solid block of frozen greens.
Another option is to freeze escarole in smaller portions, such as ice cube trays or small freezer bags. This method is convenient for adding escarole to soups, stews, or sauces, as you can simply drop in the desired amount of frozen escarole without having to thaw the entire batch. Regardless of the method you choose, be sure to label and date the containers or bags so you can easily keep track of how long they’ve been in the freezer.
How Long Can I Store Frozen Escarole?
Frozen escarole can be stored for up to 8-12 months in a 0°F (-18°C) freezer. It’s essential to store it in airtight containers or freezer bags to prevent freezer burn and maintain its quality. If you notice any signs of freezer burn, such as off-flavors or textures, it’s best to use the escarole as soon as possible. Frozen escarole is best used within 6-8 months for optimal flavor and texture.
When storing frozen escarole, it’s also important to keep it away from strong-smelling foods, as it can absorb odors easily. You can store it in the coldest part of the freezer, usually the bottom shelf, to maintain a consistent temperature. If you plan to store frozen escarole for an extended period, consider dividing it into smaller portions to make it easier to thaw and use only what you need.
Can I Use Frozen Escarole in Any Recipe?
Frozen escarole can be used in a variety of recipes, but it’s best suited for cooked dishes where it will be heated through. It’s perfect for adding to soups, stews, casseroles, and sautéed side dishes. You can also use it in place of fresh escarole in many recipes, such as escarole and beans or escarole and sausage. However, frozen escarole may not be the best choice for salads or other dishes where you want to maintain its crunchy texture.
When using frozen escarole in recipes, simply thaw it first by leaving it in room temperature for a few hours or by microwaving it according to the package instructions. Then, squeeze out as much water as possible and use it in your recipe as you would fresh escarole. Keep in mind that frozen escarole may release more water than fresh escarole, so you may need to adjust the cooking time or liquid levels in your recipe accordingly.
Is Frozen Escarole as Nutritious as Fresh Escarole?
Frozen escarole is just as nutritious as fresh escarole, as long as it’s been properly blanched and frozen.
