Kale, the undisputed king of leafy greens, has firmly established itself as a nutritional powerhouse. But with its robust, textured leaves and sometimes intimidating appearance, a common question arises: What part of kale are you actually supposed to eat? Are you limited to just the leafy parts, or is there more to this superfood than meets the eye? Let’s dive into the world of kale and unlock the secrets to enjoying every edible piece.
Exploring the Anatomy of a Kale Plant
To understand what parts of kale are edible, it’s crucial to first familiarize yourself with its basic anatomy. A kale plant typically consists of:
- Leaves: These are the most prominent and commonly consumed part of the plant. They come in various shapes, sizes, and textures depending on the kale variety.
- Stems: The stems are the central support structure of the leaves, connecting them to the main stalk.
- Stalk: The stalk is the main, thick stem from which the leaves and stems branch out.
Now, let’s break down each component and determine its edibility and best uses.
The Leafy Greens: The Star of the Show
The leaves of the kale plant are undoubtedly the star of the show. They are the primary reason most people cultivate or purchase kale. Their nutritional value and versatility make them a culinary favorite.
Different Kale Varieties and Their Leaf Characteristics
Kale comes in a fascinating array of varieties, each with its unique leaf characteristics:
- Curly Kale: Characterized by its ruffled, vibrant green leaves, curly kale is a popular choice. It has a slightly bitter taste and holds its shape well when cooked.
- Lacinato Kale (Dinosaur Kale): Also known as Tuscan kale or cavolo nero, Lacinato kale boasts long, dark green, almost black, leaves with a bumpy texture. It has a milder, slightly sweeter flavor than curly kale.
- Red Russian Kale: This variety features flat, fringed leaves with a reddish-purple hue. It has a tender texture and a slightly sweet, peppery flavor.
- Redbor Kale: Known for its intensely purple, frilly leaves, Redbor kale adds a pop of color to any dish. It has a slightly milder flavor than some other varieties.
Regardless of the variety, the leaves are packed with vitamins, minerals, and antioxidants. They can be enjoyed raw in salads, sautéed, steamed, baked into chips, or added to smoothies and soups.
Preparing the Leaves for Consumption
Before consuming kale leaves, it’s essential to prepare them properly.

To keep kale fresh for as long as possible, proper storage is crucial. The best method is to wrap the kale loosely in a paper towel and store it in a plastic bag in the crisper drawer of your refrigerator. This helps to absorb excess moisture and prevent the leaves from wilting prematurely.
Alternatively, you can store kale like fresh flowers by trimming the stems and placing them in a jar of water. Cover the leaves loosely with a plastic bag and store the jar in the refrigerator. This method keeps the kale hydrated and crisp. Regardless of the method you choose, aim to use the kale within 5-7 days for optimal freshness and flavor.
Can kale stems be composted if I choose not to eat them?
Yes, kale stems are an excellent addition to a compost pile. They are a source of green, nitrogen-rich material that helps to balance out the brown, carbon-rich materials like leaves and twigs. By adding kale stems to your compost, you’re contributing to a nutrient-rich soil amendment that can benefit your garden.
Before adding the stems to the compost pile, it’s helpful to chop them into smaller pieces to speed up the decomposition process. Layering the stems with other compost materials, such as yard waste, food scraps, and shredded paper, ensures proper aeration and moisture balance, which are essential for effective composting.
Are there any popular recipes that specifically highlight the use of kale stems?
While kale stems are often discarded, resourceful cooks have discovered creative ways to incorporate them into dishes. One popular method is to pickle the stems, creating a tangy and crunchy condiment that can be added to salads, sandwiches, or served as a side dish. Pickled kale stems offer a unique flavor and texture that complements various meals.
Another innovative use for kale stems is in soups and stews. Finely chopped stems can be added to these dishes to provide extra texture and nutrients. Simmering the stems in liquid for an extended period softens them and infuses the broth with a subtle earthy flavor. Kale stem pesto, using blanched and pureed stems along with traditional pesto ingredients, is also gaining popularity as a sustainable and flavorful alternative.
