Best Substitutes for Lemongrass
Lemongrass brings a bright, citrusy fragrance with subtle grassy notes that standard lemon juice can't match. The essential oils in the tough outer layers create that distinctive aroma, while the tender inner core adds mild lemony flavor without the acid bite. Fresh lemongrass contains about 75% water and releases oils when bruised or chopped. Most recipes use either the bottom 6 inches of the stalk (tender white part) or the whole stalk for infusing. The key to good substitutes is matching both the citrus brightness and the herbal complexity.
Best Overall Substitute
Lime zest plus fresh ginger at 1 teaspoon lime zest and 1/4 teaspoon grated ginger per lemongrass stalk. This combination captures both the citrus punch and the subtle spicy notes that make lemongrass unique. The lime provides immediate brightness while ginger adds the herbal depth.
All Substitutes
Lime zest plus fresh ginger
1 tsp lime zest + 1/4 tsp grated ginger per stalkLime zest contains similar citrus oils to lemongrass but with more intensity. Fresh ginger adds the grassy, slightly spicy notes that plain citrus misses. The combination works because lime's sharper oils soften when combined with ginger's warmth. Use the fine side of a microplane for both ingredients. Add at the same time you would add fresh lemongrass.
Lemon zest
1 teaspoon zest per lemongrass stalkLemon zest provides the citrus oils but lacks lemongrass's grassy undertones. The oils in lemon peel are more aggressive than lemongrass, so use sparingly. Works best in dishes where the lemongrass serves mainly as a bright note rather than a complex flavor layer. Add at the end of cooking to preserve the oils.
Lemongrass powder
1/2 teaspoon powder per fresh stalkDried lemongrass powder concentrates the flavor but loses the fresh herbal notes. The powder works better in cooked dishes where it has time to rehydrate and release oils. It's about 4 times stronger than fresh lemongrass. Mix with a small amount of warm water for 5 minutes before adding to activate the oils.
Lemongrass paste
1 tablespoon paste per 2 stalksCommercial lemongrass paste captures more of the original flavor than dried powder but less than fresh. Most brands blend lemongrass with oil and sometimes garlic or ginger. The paste dissolves easily and works in both quick and slow cooking methods. Store-bought versions vary widely in intensity, so start with half the recommended amount.
Kaffir lime leaves (fresh or dried)
2 leaves per lemongrass stalkKaffir lime leaves share lemongrass's citrusy intensity with added floral notes. The leaves contain similar essential oils but with a more perfumed quality. Fresh leaves work better than dried, which lose most of their oils. Tear or bruise the leaves to release oils before adding. Remove before serving as they're tough to chew.
Lemon verbena
2 tablespoons chopped fresh leaves per stalkFresh lemon verbena provides intense lemony fragrance with herbal complexity similar to lemongrass. The leaves are more delicate and work better added at the end of cooking. Dried lemon verbena loses most of its impact. The flavor is more purely lemony without lemongrass's subtle spice notes.
Lemon balm
3 tablespoons chopped fresh leaves per stalkLemon balm offers mild lemon flavor with minty undertones. It's gentler than lemongrass but provides similar herbal freshness. The leaves are tender and can stay in the dish. Works best in applications where lemongrass adds background flavor rather than starring. Add in the last 10 minutes of cooking to preserve the delicate oils.
Lemon thyme
1 tablespoon fresh leaves per stalkLemon thyme combines citrus oils with earthy thyme flavors, creating complexity similar to lemongrass. The thyme adds an herbal depth that plain lemon zest lacks. Use the leaves only, as stems can be bitter. Works particularly well in Mediterranean fusion dishes where lemongrass might feel out of place.
How to Adjust Your Recipe
When substituting lemongrass, timing matters more than with most herbs. Fresh lemongrass releases oils slowly during cooking, so it goes in early. Most substitutes are more volatile and should be added later. For curries and braises, add lemon zest or herb substitutes in the last 15 minutes. In stir-fries, add them with the aromatics but reduce heat to medium to prevent burning the delicate oils.
For infusions and teas, steep substitute herbs for 5-7 minutes maximum to avoid bitterness. Lemongrass can handle 10-15 minutes of steeping. When using zest-based substitutes in marinades, add them just before cooking rather than during long marinating times, as the oils can turn bitter after 2+ hours.
Adjust salt levels when using herb substitutes. Many contain natural sodium compounds that weren't in the original recipe. Start with 75% of the called-for salt and taste before adding more.
When Not to Substitute
Skip substitutes in traditional Thai tom yum soup or Vietnamese pho where lemongrass is essential to the authentic flavor profile. The herbal complexity can't be replicated with simple citrus. Avoid substituting in recipes where you bruise whole lemongrass stalks and remove them later, like rice dishes or slow braises, since most alternatives break down or can't be easily removed.
Lemongrass-infused simple syrups for cocktails need the real thing. The subtle oils create a specific mouthfeel that zest-based substitutes make too sharp. Whole roasted fish stuffed with lemongrass also doesn't work with substitutes since the slow heat release during roasting is key to the flavor development.
Frequently Asked Questions
How much lemon juice can I use instead of lemongrass?
Don't use lemon juice as a direct substitute. Lemon juice adds acid that changes the dish's pH and flavor balance, while lemongrass provides oils without acidity. If you must use juice, add just 1 teaspoon per 2 lemongrass stalks and increase other aromatics like garlic or ginger by 50% to compensate for the missing herbal notes.
Can I substitute dried lemongrass for fresh in curry paste?
Yes, but soak 2 tablespoons of dried lemongrass in warm water for 15 minutes first, then drain and chop finely. Use about half the amount by volume compared to fresh. The texture will be slightly different since dried lemongrass doesn't break down as smoothly, but the flavor works well in pastes that get strained or blended thoroughly.
What's the best lemongrass substitute for tea?
Use 2 strips of lemon zest plus 1 fresh mint leaf per cup of tea. Steep for 6-7 minutes maximum to avoid bitterness. This combination provides the citrus brightness and herbal freshness of lemongrass tea without being too perfumy. Fresh lemon verbena works even better if available, using 1 tablespoon of leaves per cup.
How do I make lemongrass paste at home?
Chop 6 fresh lemongrass stalks (bottom 4 inches only) and blend with 2 tablespoons neutral oil and 1/4 teaspoon salt until smooth. This makes about 1/3 cup of paste that keeps refrigerated for 2 weeks. One tablespoon of this paste equals 2 fresh stalks in most recipes.
