Leeks often get overshadowed by onions and garlic, but these mighty Alliums are a surprisingly powerful force to be reckoned with – and it doesn’t hurt that they taste AND smell amazing too! We’ll be sharing 5 powerful benefits of the criminally underrated veggie, from its gut-boosting properties to its antibacterial abilities, there’s a lot to love. Plus, we share a free, delicious recipe to help you get your leek on!
Leeks are a type of vegetable that belongs to the Allium family, which also includes onions, garlic, and shallots. They have a mild and slightly sweet flavour, similar to onions, but with a more subtle taste. Leeks have long green stalks with white bulbs at the bottom. The white and light green parts of the leek are the most commonly used in cooking, as they are tender and have a milder flavour than the dark green tops. These versatile vegetables are widely used in various cuisines around the world. They can be sautéed, roasted, grilled, or used as a flavour base in stews, and casseroles and soups – potato and leek soup, anyone? Leeks are also frequently included in salads and quiches, adding a delightful taste and texture to dishes – beat that, onion! Let’s dive into 4 reasons leeks should be on your shopping list.
They Boost Gut Health
Leeks, with their fragrant green stalks and trademark white bulbs, are more than just a flavourful addition to culinary creations; they also offer impressive benefits for gut health and digestion. Packed with dietary fibre and prebiotics, leeks play a vital role in supporting a healthy digestive system. The fibre content in leeks promotes regular bowel movements, aiding in the smooth passage of waste and preventing constipation. Additionally, the prebiotic fibre found in leeks serve as nourishment for beneficial gut bacteria, fostering a thriving gut microbiome. A balanced gut microbiome is essential for proper digestion, as it helps break down food, improves nutrient absorption, and supports the body's immune function. By incorporating leeks into your diet, whether in soups, salads, or stir-fries, you can enjoy not only their delightful taste but also the digestive benefits that contribute to your overall well-being.
They Improve Heart Health
Beyond their subtle sweet taste and vibrant appearance, leeks wield a potent defence against heart disease. Rich in antioxidants like flavonoids and polyphenols, leeks act as stalwart protectors, shielding our cardiovascular system from harm. These antioxidants neutralise free radicals, which are harmful molecules that can damage cells and contribute to heart disease. Moreover, the sulphur compounds in leeks, particularly when cooked, produce allicin, a powerful ally in the battle against heart disease. Allicin has been shown to lower cholesterol levels, thus reducing the risk of plaque build-up in arteries and supporting overall heart health. Embracing leeks as a regular part of our diet can be a heart-smart decision, helping to safeguard our most vital organ and promoting a life filled with heartiness and vitality.
They Strengthen Your Hair
Leeks can contribute to improved hair health due to the presence of certain nutrients and compounds that support hair growth and strength:
- Vitamin A: Leeks contain vitamin A, which is essential for maintaining healthy hair. Vitamin A helps the scalp produce sebum, an oily substance that moisturises the scalp and keeps the hair follicles healthy.
- Silicon: Leeks are a natural source of silicon, a mineral that plays a role in maintaining hair strength and elasticity. Silicon is believed to help improve hair texture and reduce brittleness.
- Antioxidants: Leeks are rich in antioxidants, including flavonoids and polyphenols. These antioxidants protect the hair follicles from oxidative stress and damage caused by free radicals, helping to maintain healthy hair growth.
- Nutrient Support: The vitamins and minerals in leeks, such as vitamin C, vitamin K, and folate, contribute to overall scalp health and hair nourishment.
They May Reduce Your Risk For Cancer
Leeks may potentially combat cancer due to their content of certain compounds that have been associated with anti-cancer properties. While research on the specific effects of leeks on cancer is ongoing and not conclusive, here are some factors that suggest their potential anti-cancer benefits:
- Organosulfur Compounds: Leeks, like other members of the Allium family (such as garlic and onions), contain organosulfur compounds, including allicin. These compounds have demonstrated antioxidant and anti-inflammatory properties and have been linked to potential anti-cancer effects in preclinical studies.
- Antioxidants: Leeks are rich in antioxidants, such as flavonoids and polyphenols. These compounds help neutralise harmful free radicals, which can damage cells and contribute to the development of cancer.
- Quercetin: Leeks contain quercetin, a flavonoid with anti-inflammatory and potential anti-cancer properties. Quercetin has been studied for its ability to inhibit the growth of cancer cells and induce apoptosis (programmed cell death) in cancer cells in laboratory settings.
- Nutrient Density: Leeks are a nutritious vegetable, providing essential vitamins and minerals that support overall health. A well-balanced diet that includes nutrient-rich foods like leeks can contribute to overall well-being, including a potential reduced risk of certain cancers.

Creamy Potato + Leek Soup
- 2 large leeks (white and light green parts only), cleaned and thinly sliced
- 3 medium potatoes, peeled and diced
- 1 small onion, chopped
- 2 cloves garlic, minced
- 4 cups vegetable or chicken broth
- 1 cup milk or unsweetened plant-based milk
- 2 tablespoons butter or olive oil
- Salt and pepper to taste
- Fresh chives or parsley for garnish (optional)
- In a large soup pot, heat the butter or olive oil over medium heat. Add the chopped onion and minced garlic, and sauté for about 2-3 minutes until the onions become translucent.
- Add the sliced leeks to the pot, and cook for another 3-4 minutes, stirring occasionally, until the leeks are soft and slightly caramelised.
- Add the diced potatoes to the pot and season with salt and pepper to taste. Stir everything together and let it cook for another 2 minutes.
- Pour in the vegetable or chicken broth, and bring the mixture to a boil. Once it starts boiling, reduce the heat to low, cover the pot, and let it simmer for about 15-20 minutes or until the potatoes are tender and fully cooked.
- Using an immersion blender or a regular blender (in batches), blend the soup until smooth and creamy. If using a regular blender, be sure to let the soup cool slightly before blending to avoid splattering.
- Pour the blended soup back into the pot, and stir in the milk. Cook over low heat for another 2-3 minutes, allowing the flavours to meld together.
- Taste the soup and adjust the seasoning with more salt and pepper if needed.
- Serve the creamy leek and potato soup hot, garnished with fresh chives or parsley if desired.
