The Surprising Truth About Broccoli Leaves
For many home cooks and consumers, the fate of broccoli leaves is the compost pile or the trash bin. However, these nutrient-dense greens deserve a place on your plate. Historically, farmers considered them a byproduct, but shifting attitudes toward food waste and the rise of specialty produce have brought them into the culinary spotlight. Understanding what they are called is the first step toward embracing this delicious and versatile ingredient.
Commercial Names: The Rise of BroccoLeaf
In the United States, one of the most prominent commercial names for broccoli leaves is BroccoLeaf. This trademarked name was introduced by produce company Foxy Produce to market the leaves as a new 'super green' in 2014. The branding positions them alongside other popular leafy greens like kale and Swiss chard, highlighting their versatility and health benefits. This strategic move was intended to reduce food waste and introduce consumers to a previously overlooked part of the plant.
Regional Names: Spigariello and Cima di Rapa
Across the Atlantic, a variety of broccoli grown specifically for its leaves is a staple in Italian cuisine. Known as Spigariello, or more formally as Cima di rape Spigarello or Cavolo Broccolo Spigariello, this leafy vegetable is distinct from the broccoli typically found in US supermarkets. Spigariello leaves have a milder, subtly sweet flavor with grassy and mildly bitter undertones, making them a popular ingredient in dishes like minestra maritata, a traditional Neapolitan soup. While technically a different cultivar, its common name and purpose shed light on the culinary tradition of using broccoli-family leaves.
The Botanical Name: Brassica oleracea
From a botanical perspective, broccoli leaves belong to the species Brassica oleracea, which also includes a wide range of other familiar vegetables, such as cabbage, kale, collard greens, and cauliflower. This close relationship explains why broccoli leaves share similar characteristics and nutritional profiles with these other members of the cabbage family. When growing your own broccoli, these large, leathery leaves are the same species as traditional collards, reinforcing their edibility and potential culinary uses.
How to Prepare and Use Broccoli Leaves
Broccoli leaves can be used in a wide variety of raw and cooked applications. Their flavor profile is often described as earthy and slightly less bitter than kale. Younger leaves are more tender and can be enjoyed raw, while larger, more mature leaves benefit from cooking to soften their texture. Here are some ways to prepare them:
- Sautéing: Sauté the leaves with garlic and olive oil for a simple and flavorful side dish, similar to preparing collard greens or chard.
- Smoothies: Blend younger, tender leaves into a green smoothie for an extra boost of vitamins without significantly altering the flavor.
- Salads and Wraps: Thinly slice or chop raw, young leaves to add a fresh, crunchy element to salads and sandwiches.
- Soups and Stews: Add larger, tougher leaves to soups, stews, or pasta sauces, allowing them to simmer and become tender.
- Roasted Chips: Toss the leaves with a little oil and seasoning, then roast them in the oven until crispy for a nutritious alternative to kale chips.
Nutritional Powerhouse: Leaves vs. Florets
While broccoli florets are widely celebrated for their health benefits, the leaves are in fact even more nutrient-dense in several key areas. Eating the whole plant is an excellent way to maximize nutritional intake and minimize food waste. Below is a comparison of the general nutritional benefits of broccoli leaves and florets.
| Nutrient | Broccoli Leaves | Broccoli Florets |
|---|---|---|
| Vitamins A & K | Significantly higher content | Present, but in lesser quantities |
| Calcium | Higher concentration | Present |
| Antioxidants | Higher levels of phytonutrients | Rich source of sulforaphane |
| Fiber | Excellent source, especially in stems | Good source |
| Vitamin C | Excellent source, especially when raw or lightly cooked | Particularly rich source |
| Flavor Profile | Earthy, mild, kale-like | Characteristically “broccoli,” slightly sulfurous when cooked |
Culinary Applications Beyond the Obvious
Utilizing broccoli leaves goes beyond just substituting them for other leafy greens. You can get creative with recipes that highlight their unique texture and flavor. For example, a pesto made from broccoli leaves and stems can offer a uniquely earthy twist on the classic sauce. The entire plant—leaves, stems, and florets—can be incorporated into a stir-fry, creating a zero-waste, nutrient-packed dish. When harvesting leaves from your own garden, picking the outer leaves regularly acts as a cut-and-come-again crop, extending your harvest.
Conclusion: Don't Discard the Greens!
So, what are broccoli leaves called? While there's no single universal term, commercial products may be branded as "BroccoLeaf," while Italian varieties are known as Spigariello. Fundamentally, they are simply the edible leaves of the Brassica oleracea plant. By understanding their names and recognizing their nutritional value, we can reduce food waste and expand our culinary horizons. The next time you encounter a whole head of broccoli with its leaves attached, remember that you have a free, delicious, and nutritious superfood ready to be used.
