Kale has surged in popularity as a nutritional powerhouse, gracing plates in salads, smoothies, and countless other dishes. But did you know that “kale” isn’t a monolithic entity? Within the kale family, different varieties offer unique characteristics. Two of the most common and distinctly different types are lacinato kale and regular kale, often referring to curly kale. Understanding the differences between these two can help you make informed choices about which to incorporate into your diet and how to best prepare them.
Understanding the Basics: What is Kale?
Kale is a leafy green vegetable belonging to the Brassica family, which also includes broccoli, cabbage, cauliflower, and collard greens. Known for its impressive nutritional profile, kale is packed with vitamins, minerals, and antioxidants. It’s a versatile ingredient that can be enjoyed raw, cooked, or even dehydrated into crispy chips. The different varieties of kale stem from variations in leaf structure, color, and taste.
Lacinato Kale: The Dinosaur of the Kale World
Lacinato kale, also known as dinosaur kale, Tuscan kale, or cavolo nero (Italian for “black cabbage”), stands out with its distinctive appearance. Its leaves are long, narrow, and deeply crinkled, resembling the skin of a dinosaur, hence its nickname. The color is a deep, blue-green, almost black, giving it an elegant and sophisticated look.
Taste and Texture of Lacinato Kale
One of the most significant differences between lacinato and regular kale lies in their taste and texture. Lacinato kale has a more delicate and slightly sweeter flavor compared to the more robust and sometimes bitter taste of curly kale. Its texture is also more tender, making it suitable for both raw and cooked preparations. When cooked, it becomes even more tender and melts in your mouth.
Culinary Uses for Lacinato Kale
Lacinato kale’s milder flavor and tender texture make it a versatile ingredient in the kitchen. It’s excellent in salads, especially when massaged with olive oil and lemon juice. It can also be sautéed, braised, or added to soups and stews. Its slightly nutty flavor pairs well with various ingredients, from garlic and onions to parmesan cheese and toasted nuts. In Italian cuisine, it is a key ingredient in ribollita, a hearty Tuscan bread and vegetable soup.
Regular Kale: The Curly Classic
“Regular” kale typically refers to curly kale, the most common type found in supermarkets. Its leaves are bright green and tightly curled, creating a visually appealing texture. Unlike lacinato kale, curly kale has a more pronounced, slightly bitter flavor and a tougher texture.
Taste and Texture of Regular Kale
The flavor of curly kale is often described as earthy and slightly bitter. This bitterness can be more pronounced in mature leaves. Its texture is also significantly tougher than that of lacinato kale, requiring more effort to chew, especially when raw. However, the bitterness and toughness can be mitigated through proper preparation techniques, such as massaging the leaves with oil or blanching them before use.
Culinary Uses for Regular Kale
While curly kale can be used in similar ways to lacinato kale, its stronger flavor and tougher texture often dictate different preparation methods. It is well-suited for hearty dishes like soups, stews, and stir-fries, where its robust flavor can stand up to other ingredients. It’s also a popular choice for making kale chips, as its curly leaves provide ample surface area for crisping. Massaging it with oil and lemon juice helps to tenderize it for salads, but it may still retain a slightly tougher texture compared to lacinato kale.
Nutritional Showdown: Lacinato Kale vs. Regular Kale
Both lacinato and regular kale are nutritional powerhouses, boasting an impressive array of vitamins, minerals, and antioxidants. They are both excellent sources of vitamins A, C, and K, as well as calcium, potassium, and fiber. While their nutritional profiles are similar, there are some subtle differences.
Vitamin and Mineral Content
Generally speaking, both types of kale are incredibly nutrient-dense. They are both excellent sources of Vitamin K, which is crucial for blood clotting and bone health. Vitamin A, important for vision and immune function, is also abundant in both. They also contain good amounts of Vitamin C, an antioxidant that supports the immune system and helps protect against cell damage. Mineral-wise, both offer calcium, important for bone health, and potassium, which helps regulate blood pressure.
Antioxidant Power
Kale is known for its high antioxidant content, which helps protect the body against damage from free radicals. Both lacinato and regular kale contain various antioxidants, including flavonoids and carotenoids. These compounds have been linked to a reduced risk of chronic diseases, such as heart disease and cancer.
Fiber Content
Fiber is another important nutrient found in both types of kale. Fiber promotes healthy digestion, helps regulate blood sugar levels, and can contribute to feelings of fullness, aiding in weight management. Both lacinato and curly kale are good sources of dietary fiber.
Choosing the Right Kale for Your Needs
The best type of kale for you depends on your personal preferences and how you plan to use it. If you prefer a milder flavor and more tender texture, lacinato kale is an excellent choice. Its versatility makes it suitable for salads, sautés, and other dishes where you want a more delicate flavor.
If you prefer a more robust flavor and don’t mind a slightly tougher texture, curly kale is a good option. Its heartier nature makes it well-suited for soups, stews, and kale chips.
Consider these factors when deciding between lacinato and regular kale:
- Taste preference: Do you prefer a milder, slightly sweet flavor or a more robust, earthy flavor?
- Texture preference: Do you prefer a tender texture or a slightly tougher texture?
- Cooking method: How do you plan to prepare the kale? Salads benefit from the tenderness of lacinato, while hearty dishes like stews can handle the heartiness of curly kale.
- Availability: Which type of kale is readily available at your local grocery store or farmers market?
Preparing and Cooking Kale: Tips and Tricks
Regardless of which type of kale you choose, proper preparation can enhance its flavor and texture. Here are some tips for preparing and cooking kale:
- Washing: Thoroughly wash the kale leaves to remove any dirt or debris.
- Removing the stems: The stems of kale can be tough and bitter. Remove them by stripping the leaves from the stem or cutting them out with a knife.
- Massaging (for salads): Massaging kale with olive oil and lemon juice helps to break down the fibers and make it more tender and palatable for salads.
- Cooking: Kale can be cooked in various ways, including sautéing, steaming, boiling, and baking. Cooking time will vary depending on the type of kale and the desired texture.
- Seasoning: Kale can be seasoned with a variety of flavors, including garlic, onions, salt, pepper, lemon juice, and parmesan cheese.
Growing Your Own Kale: A Rewarding Experience
Growing your own kale is a rewarding experience that allows you to enjoy fresh, homegrown produce. Kale is relatively easy to grow and can thrive in a variety of climates.
Here are some tips for growing kale:
- Planting: Kale can be planted in early spring or late summer.
- Sunlight: Kale prefers full sun but can tolerate partial shade.
- Soil: Kale grows best in well-drained soil that is rich in organic matter.
- Watering: Water kale regularly, especially during dry periods.
- Harvesting: Kale can be harvested as needed. Simply cut off the outer leaves, and the plant will continue to produce new leaves.

What are the main visual differences between Lacinato kale and regular curly kale?
Lacinato kale, also known as dinosaur kale or Tuscan kale, has long, narrow, and deeply ridged leaves. They are a dark blue-green color and appear almost prehistorically textured, hence the nickname. Regular curly kale, on the other hand, has tightly curled and ruffled leaves that are a lighter green shade. Its leaves tend to be broader and bushier compared to the sleek, elongated appearance of Lacinato kale.
The visual distinctions extend beyond the leaf shape. Lacinato kale’s stalks are also generally thinner and more tender than the thicker, tougher stalks found in curly kale. This difference in stalk texture impacts preparation methods, as the stalks of curly kale often require more cooking time or removal before eating. Lacinato kale stalks can usually be consumed alongside the leaves without significant textural difference.
How does the taste of Lacinato kale compare to the taste of regular curly kale?
Lacinato kale offers a more subtle and delicate flavor profile compared to curly kale. It’s often described as earthy, slightly sweet, and with a hint of nuttiness. Its flavor becomes even milder and sweeter when cooked, making it a versatile ingredient for a variety of dishes. The lack of bitterness is a key appeal for many who find curly kale overpowering.
Curly kale possesses a much more robust and assertive flavor. It has a pronounced bitterness that some find appealing, while others find it off-putting. The bitterness is due to compounds called glucosinolates, which are more concentrated in curly kale. Proper preparation methods, such as massaging with oil or blanching, can help to mitigate this bitterness.
Which type of kale, Lacinato or regular, is better for salads?
Lacinato kale is often preferred for salads due to its more tender texture and milder flavor. When massaged with oil and acid, its leaves soften beautifully, making them easier to chew and digest raw. The subtle sweetness complements other salad ingredients without overpowering them. Its elongated shape also presents well in a salad.
Curly kale can be used in salads, but it typically requires more preparation. Massaging with oil is essential to break down the tough fibers and reduce its inherent bitterness. Some people also blanch curly kale briefly before adding it to a salad. While it can add a robust flavor and textural contrast, it’s crucial to properly prepare it to avoid a tough and bitter salad.
In terms of nutritional value, are there significant differences between Lacinato kale and regular kale?
Both Lacinato kale and curly kale are nutritional powerhouses, packed with vitamins, minerals, and antioxidants. They are excellent sources of vitamins A, C, and K, as well as calcium and fiber. While their nutritional profiles are broadly similar, there can be slight variations in the concentration of specific nutrients.
Studies suggest that curly kale may contain slightly higher levels of certain glucosinolates, the compounds responsible for its bitter taste, which also have potential health benefits. However, Lacinato kale still provides a significant amount of these beneficial compounds, along with a potentially higher concentration of certain antioxidants. Ultimately, both types of kale contribute significantly to a healthy diet.
Which cooking methods are best suited for Lacinato kale versus regular curly kale?
Lacinato kale is a versatile green that adapts well to a wide range of cooking methods. Its tender leaves make it suitable for sautéing, steaming, roasting, and even grilling. It cooks relatively quickly, retaining a pleasant texture without becoming overly tough. It’s a great addition to soups, stews, pasta dishes, and stir-fries.
Curly kale, due to its tougher texture, often benefits from longer cooking times. It’s excellent for braising, where it can tenderize and absorb flavors beautifully. It can also be used in soups and stews, but it might require a longer cooking time to soften. When roasting curly kale, it’s important to ensure it’s adequately oiled to prevent it from drying out.
Which type of kale is easier to find in grocery stores?
Regular curly kale is typically more widely available in most grocery stores. It’s a common and well-established variety, often stocked year-round. Its popularity and ease of cultivation contribute to its consistent presence in the produce section.
Lacinato kale, while becoming increasingly popular, might not be as readily available as curly kale in all locations. It’s more likely to be found in larger grocery chains, farmers’ markets, or specialty produce stores. The seasonal availability of Lacinato kale might also vary depending on the region and growing conditions.
How does the price of Lacinato kale compare to the price of regular curly kale?
Generally, Lacinato kale tends to be slightly more expensive than regular curly kale. This price difference often reflects its relative scarcity and the slightly more specialized cultivation practices it may require. The higher demand for its more subtle flavor profile can also contribute to its higher cost.
The price difference, however, is usually not significant enough to deter most consumers. Both types of kale are relatively affordable options for adding nutrient-rich greens to your diet. Prices can also fluctuate depending on the season, location, and the specific grocery store.
