Escarole, often mistaken for lettuce, is a fascinating leafy green with a slightly bitter taste and a robust texture. It’s a member of the chicory family, which also includes endive, radicchio, and frisée. While often grouped together, these chicories have distinct characteristics. The question then arises: are there different kinds of escarole, or is it simply escarole, end of story? The answer, as with many natural products, is nuanced. While technically speaking, the variations are often considered cultivars of the same species, Cichorium endivia, understanding these subtle differences can significantly impact your culinary experience.
Understanding Escarole: More Than Just a Green Leaf
Before diving into the different kinds of escarole, it’s essential to understand what makes escarole unique. Its leaves are broader and less curly than endive, another close relative. The inner leaves tend to be lighter in color and milder in flavor, while the outer leaves are darker green and possess a more pronounced bitterness. This bitterness is a hallmark of the chicory family and is due to the presence of certain compounds, which some find appealing and others prefer to minimize.
Escarole is a versatile ingredient, finding its place in salads, soups, stews, and even as a cooked side dish. Its sturdiness allows it to hold up well under heat, unlike more delicate lettuces that wilt quickly. This versatility is partly why it’s so popular in various cuisines around the world, particularly Italian and Mediterranean cooking.
Cultivars and Variations: Exploring the Escarole Spectrum
While the botanical classification may primarily focus on Cichorium endivia, the agricultural world recognizes several cultivars of escarole. These cultivars have been developed over time through selective breeding to enhance certain traits, such as leaf shape, size, bitterness level, and cold hardiness. While you may not find them explicitly labeled in the grocery store, understanding these variations can help you select the right escarole for your cooking needs.
Batavian Full Heart: A Popular Choice
One of the most common types of escarole is the Batavian Full Heart. It’s characterized by its large, broad leaves that form a dense, tightly packed head.

Batavian Full Heart is known for its crisp texture and good shelf life, making it a favorite among growers and consumers alike. This variety is particularly well-suited for salads and braising.
Broad Leaved Batavian: A Subtle Variation
Similar to the Batavian Full Heart, the Broad Leaved Batavian escarole also features wide leaves but might exhibit a slightly looser head formation. The taste profile is comparable, with a pleasant bitterness balanced by sweeter inner leaves. This cultivar is often used interchangeably with Batavian Full Heart in recipes.
Escarole Gigante: The Giant of the Greens
As the name suggests, Escarole Gigante is a larger variety of escarole, boasting significantly bigger leaves than other cultivars. This makes it an excellent choice for wrapping or stuffing, as well as for use in cooked dishes where its size allows it to stand out. The flavor profile is similar to other escaroles, with the typical bitter notes.
Other Regional and Heirloom Varieties
Beyond these common cultivars, there are various regional and heirloom varieties of escarole that may be available in specialty markets or through local farmers. These varieties often possess unique characteristics, such as slightly different leaf shapes, colors, or flavor profiles. They might also be adapted to specific growing conditions, making them more suitable for certain regions. Unfortunately, these varieties often lack specific names that are readily available to the average consumer.

From the popular Batavian Full Heart to the larger Escarole Gigante, these subtle differences can significantly impact the flavor and texture of your dishes. By understanding these nuances and employing techniques to manage its bitterness, you can fully appreciate the versatility and nutritional benefits of this often-underestimated leafy green. So, the next time you’re at the grocery store, take a closer look at the escarole – you might just discover a new favorite.
What exactly is escarole, and where does it fit within the world of leafy greens?
Escarole is a leafy green vegetable belonging to the chicory family, which also includes endive, radicchio, and frisée. It’s characterized by broad, slightly bitter leaves that are typically lighter green and more tender towards the center of the head, graduating to darker green and more robust outer leaves. Unlike lettuce, escarole possesses a distinct bitterness that mellows when cooked, making it a versatile ingredient for both raw and cooked applications.
The chicory family is known for its characteristic bitterness, which is due to compounds called sesquiterpene lactones. Escarole’s bitterness is less intense than that of radicchio or some varieties of endive, making it a good starting point for those new to chicory greens. It’s often compared to endive but has broader, less curly leaves. Escarole’s adaptability and nutritional value make it a popular choice in various cuisines around the world.
Are there different varieties of escarole available for consumption?
While the term “escarole” is commonly used to refer to a single vegetable, there are subtle variations within the species that might be considered different types. These distinctions primarily arise from factors like growing conditions, seed strains, and the specific cultivars chosen by farmers. These variations influence the leaf shape, color intensity, and overall texture of the escarole.
Generally, you won’t find escarole labeled with specific cultivar names in most grocery stores. However, you may encounter variations in leaf width (broader versus more narrow), level of curliness (some being slightly frillier than others), and the intensity of the green color. These differences, though subtle, can affect the flavor profile and best use of the escarole in cooking. For example, some might be better suited for salads while others hold up better in soups.
What are the key differences between escarole and endive, and how can I tell them apart?
Escarole and endive, both members of the chicory family, are often confused due to their similar appearance and slightly bitter flavor profiles. However, there are distinct visual and textural differences that make them relatively easy to distinguish. Escarole features broad, slightly curly leaves that are typically pale green at the center and darker green towards the outer edges. Endive, on the other hand, has narrower, tightly curled leaves with a more pronounced bitterness.
Another key difference lies in their texture. Escarole leaves are generally more tender and less bitter than endive, particularly the inner leaves. Endive, especially the tightly packed head, has a crisper, more robust texture and a sharper, more intense bitter flavor. This difference in texture and bitterness impacts how each is best used in cooking; escarole is often cooked to mellow its bitterness, while endive is frequently enjoyed raw in salads or braised.
How does the flavor of escarole change depending on how it is prepared?
The flavor of escarole is significantly affected by the method of preparation. Raw escarole has a distinct bitterness that can be quite pronounced, especially in the darker green outer leaves. However, this bitterness can be balanced by pairing it with sweeter or tangy ingredients in salads, such as citrus fruits, creamy dressings, or roasted vegetables.
When cooked, escarole’s bitterness mellows considerably. Braising, sautéing, or adding it to soups softens both the texture and the flavor, resulting in a more palatable and less intense taste. Cooking allows the sugars within the vegetable to become more prominent, creating a sweeter, more nuanced flavor profile. This adaptability makes escarole a versatile ingredient for a wide range of culinary applications.
What are the nutritional benefits of including escarole in my diet?
Escarole is a nutrient-rich leafy green that offers numerous health benefits when incorporated into a balanced diet. It is an excellent source of vitamins, particularly vitamin A, vitamin C, and vitamin K. Vitamin A is crucial for vision, immune function, and cell growth; vitamin C is a powerful antioxidant that supports the immune system; and vitamin K is essential for blood clotting and bone health.
Furthermore, escarole is a good source of dietary fiber, which aids in digestion, promotes satiety, and helps regulate blood sugar levels. It also contains minerals like potassium and folate. Potassium plays a role in maintaining healthy blood pressure, while folate is vital for cell growth and development, particularly during pregnancy. The low calorie and carbohydrate content of escarole makes it a healthful addition to many diets.
Are there any potential drawbacks or considerations when consuming escarole?
While escarole is generally safe and healthy for most people, there are a few potential drawbacks to consider. Its natural bitterness might not appeal to everyone, especially those with a sensitive palate. However, as mentioned earlier, cooking methods can mitigate this bitterness. It’s also worth noting that escarole, like other leafy greens, contains oxalates, which can bind to calcium and other minerals, potentially reducing their absorption.
For individuals prone to kidney stones, consuming large quantities of oxalate-rich foods like escarole may increase the risk of stone formation. Moderate consumption as part of a balanced diet is typically not a concern, but those with kidney problems should consult with a healthcare professional. Additionally, individuals taking blood-thinning medications, such as warfarin, should be mindful of their vitamin K intake, as escarole is a good source of this vitamin, and consistent intake is important to maintain stable medication levels.
What are some creative and delicious ways to incorporate escarole into my meals?
Escarole’s versatility lends itself to numerous culinary applications. It can be enjoyed raw in salads, offering a slightly bitter counterpoint to sweeter or creamier ingredients. Massaging the raw escarole leaves with a vinaigrette can help to tenderize them and reduce the bitterness. It also pairs well with fruits like oranges or pears, and cheeses like gorgonzola or parmesan.
When cooked, escarole becomes incredibly tender and its bitterness mellows, making it a wonderful addition to soups, stews, and braised dishes. It is commonly used in Italian-American cuisine, often featured in escarole and bean soup or sautéed with garlic and olive oil. It can also be used as a pizza topping, added to pasta dishes, or even grilled for a smoky flavor. Its adaptability makes it a valuable addition to any home cook’s repertoire.
