Lemongrass, with its vibrant citrusy aroma and flavor, is a staple in many cuisines around the world, particularly in Southeast Asia. But do you truly utilize every part of this fragrant herb, or are you discarding valuable components that could enhance your culinary creations and even contribute to your well-being? The answer, for many, is likely no. Most home cooks and even some chefs tend to focus primarily on the tender inner stalks, often overlooking the flavorful leaves and the tougher outer layers. This article delves into the multifaceted uses of lemongrass, guiding you on how to unlock its full potential, minimizing waste, and maximizing its benefits.
Understanding the Anatomy of Lemongrass
Before exploring the various ways to use lemongrass, it’s essential to understand its anatomy. Lemongrass typically comprises three main parts: the bulbous base, the stalk, and the leafy tops. Each part has its unique characteristics and suitability for different applications.
The Bulbous Base: The Heart of Flavor
The bulbous base, also known as the root end, is the most tender and flavorful part of the lemongrass stalk. It contains the highest concentration of essential oils, which contribute to its characteristic citrusy and slightly floral aroma. This section is ideal for adding a strong lemongrass flavor to curries, soups, stews, and marinades.
The Stalk: Versatile and Aromatic
The stalk, located above the bulbous base, is less tender but still packed with flavor. It can be used in various ways, depending on its size and maturity. The inner, more tender parts of the stalk are suitable for cooking, while the tougher outer layers can be used for infusions and broths.
The Leafy Tops: Often Discarded, but Surprisingly Useful
The leafy tops, the green portion of the lemongrass plant, are often discarded. However, they still contain a significant amount of flavor and can be used to make teas, infusions, and even as a natural insect repellent. While the texture is generally too tough for direct consumption, their aromatic properties make them a valuable ingredient in various applications.
Culinary Uses of Lemongrass: From Base to Tip
Lemongrass is incredibly versatile in the kitchen, adding a bright, refreshing flavor to a wide range of dishes. By understanding how to use each part of the plant, you can elevate your cooking and minimize waste.
Utilizing the Bulbous Base in Cooking
The bulbous base is best used by finely mincing or pounding it into a paste. This releases the essential oils and allows the flavor to infuse into your dish.
- Curries and Soups: Add minced lemongrass base to Thai green curry, tom yum soup, or Vietnamese pho for an authentic flavor.
- Marinades: Combine minced lemongrass with ginger, garlic, and soy sauce for a flavorful marinade for chicken, pork, or seafood.
- Stir-fries: Stir-fry minced lemongrass with other aromatic ingredients like garlic and chili for a flavorful base for your stir-fries.
Cooking with the Lemongrass Stalk
The lemongrass stalk can be used whole, crushed, or finely sliced, depending on the desired intensity of flavor.
- Infusions: Bruise the stalk by gently pounding it with the back of a knife, then add it to boiling water to create a lemongrass infusion. This infusion can be used as a base for soups, sauces, or even cocktails.
- Flavoring Broths: Add whole or halved lemongrass stalks to chicken, vegetable, or fish broths for a subtle citrusy flavor. Remember to remove the stalks before serving.
- Grilling: Use lemongrass stalks as skewers for grilling chicken, shrimp, or vegetables. The lemongrass will impart a subtle flavor to the food as it cooks.
- Finely Sliced: Thinly slice the tender inner parts of the stalk and add them to salads, spring rolls, or noodle dishes for a burst of flavor.
Repurposing the Leafy Tops: Beyond the Trash Bin
Don’t discard the leafy tops! They can be used in various ways to add flavor and aroma to your creations.
- Lemongrass Tea: Simmer the leafy tops in water to create a refreshing and aromatic lemongrass tea. You can add ginger, honey, or lemon to customize the flavor.
- Infused Oils: Add the leafy tops to olive oil or other cooking oils to create a lemongrass-infused oil. This oil can be used for cooking, salad dressings, or even as a massage oil.

Tips for Buying, Storing, and Preparing Lemongrass
To ensure you’re getting the most out of your lemongrass, it’s important to buy it fresh, store it properly, and prepare it correctly.
Choosing Fresh Lemongrass
When buying lemongrass, look for stalks that are firm, plump, and light green in color. Avoid stalks that are dry, shriveled, or have brown spots. The base of the stalk should be slightly bulbous. The leaves should be green and fresh-looking.
Storing Lemongrass for Optimal Freshness
Lemongrass can be stored in several ways to prolong its freshness:
- Refrigerator: Wrap fresh lemongrass stalks in a damp paper towel and store them in a plastic bag in the refrigerator for up to two weeks.

- Water: Stand lemongrass stalks in a jar of water, like cut flowers, and keep them in the refrigerator. Change the water every few days.
Preparing Lemongrass for Cooking
Before using lemongrass in your cooking, you’ll need to prepare it properly.

- Trim the Base: Trim the root end of the stalk.
- Remove Outer Layers: Remove any dry or damaged outer layers of the stalk.
- Bruise or Slice: Depending on the recipe, you can bruise the stalk by pounding it with the back of a knife to release its flavor, or you can slice it thinly. For mincing, use only the tender inner part of the base.

Can I eat the tough, outer stalks of lemongrass?
The tough, outer stalks of lemongrass, while not typically consumed directly due to their fibrous texture, are still packed with flavor and aroma. Don’t discard them! These outer leaves are ideal for infusing flavor into stocks, soups, and broths. Their robust flavor will permeate the liquid, adding depth and complexity to your dishes.
To utilize them, simply bruise the stalks gently to release their essential oils, then simmer them in your chosen liquid. Remove them before serving, as they remain tough and difficult to chew. Think of them like bay leaves – essential for flavor, but not meant for consumption.
What parts of the lemongrass plant are typically used in cooking?
Generally, the lower bulbous end and the tender inner stalks of lemongrass are the most commonly used parts in cooking. The bulb contains the highest concentration of essential oils, offering the most intense flavor. The inner stalks, while milder than the bulb, are still flavorful and have a more tender texture suitable for chopping and adding directly to dishes.
These portions can be finely minced, pounded into a paste, or sliced thinly depending on the recipe. In contrast to the outer stalks, these parts are often added directly to dishes without being removed later, offering a more direct burst of lemongrass flavor. However, even these more tender portions are often removed before serving if they haven’t been finely processed.
How can I store lemongrass to keep it fresh?
Fresh lemongrass can be stored in several ways to prolong its shelf life. For short-term storage, simply wrap the lemongrass stalks loosely in a damp paper towel and store them in the refrigerator crisper drawer. This will help retain moisture and prevent them from drying out.
For longer-term storage, you can freeze lemongrass stalks whole or sliced. Before freezing, consider wrapping them tightly in plastic wrap or placing them in an airtight freezer bag. Frozen lemongrass can be used directly in cooking without thawing, making it a convenient option for keeping this aromatic herb on hand.
Can I grow lemongrass myself?
Yes, lemongrass is relatively easy to grow, especially in warmer climates. You can propagate lemongrass from stalks purchased at the grocery store or a local market. Place the stalks in a glass of water, ensuring the base is submerged, and wait for roots to develop.
Once roots have grown to a sufficient length, typically a few inches, you can transplant the lemongrass into a pot or directly into the ground. Lemongrass thrives in well-drained soil and requires plenty of sunlight. Regular watering is essential, especially during warmer months, to ensure healthy growth and a bountiful harvest.
Are there any medicinal benefits associated with lemongrass?
Lemongrass has been used in traditional medicine for centuries and is believed to offer several potential health benefits. It’s a source of antioxidants and may possess anti-inflammatory and antimicrobial properties. Some studies suggest that lemongrass may help relieve anxiety, lower cholesterol, and improve digestion.
Furthermore, lemongrass tea is often used as a remedy for colds and flu due to its soothing and decongestant properties. The volatile oils in lemongrass, such as citral, are believed to contribute to these potential health benefits. However, it’s crucial to consult with a healthcare professional before using lemongrass for medicinal purposes, particularly if you have any existing health conditions or are taking medications.
What are some alternative uses for lemongrass besides cooking?
Beyond culinary applications, lemongrass offers a range of alternative uses. The aromatic essential oils in lemongrass make it a popular ingredient in natural cleaning products and insect repellents. The strong citrusy scent can effectively deter mosquitoes and other pests.
Lemongrass essential oil is also frequently used in aromatherapy for its calming and uplifting properties. Diffusing lemongrass oil can help reduce stress and promote relaxation. Additionally, lemongrass can be incorporated into homemade soaps and lotions for its refreshing fragrance and potential skin benefits.
Can lemongrass be dried for later use?
Yes, lemongrass can be successfully dried for later use, although the flavor will be somewhat less intense than fresh lemongrass. To dry lemongrass, spread the stalks thinly on a baking sheet and dry them in a low oven (around 170°F or 77°C) until they are completely brittle. Alternatively, you can use a dehydrator following the manufacturer’s instructions.
Once dried, store the lemongrass in an airtight container in a cool, dark place. Dried lemongrass can be added to soups, stews, and teas. Remember that you may need to use a larger quantity of dried lemongrass to achieve the same level of flavor as fresh.
