What Is Lemongrass Spice? Your Complete Answer

Lemongrass spice is a dried, ground form of the lemongrass plant (Cymbopogon citratus) that delivers a bright, citrusy flavor without the acidity of lemon. Unlike fresh lemongrass stalks—which are fibrous and require special preparation—lemongrass spice offers convenience for home cooks seeking authentic Southeast Asian flavors. One teaspoon of dried lemongrass powder equals one fresh stalk, making it perfect for soups, curries, marinades, and even desserts when used properly.

Fresh vs Dried Lemongrass: What's the Difference?

Understanding the distinction between fresh and dried lemongrass is crucial for perfect results in your cooking. Fresh lemongrass consists of long, fibrous stalks with a subtle citrus aroma that requires bruising or mincing to release flavors. Lemongrass spice (dried and ground) concentrates the flavor, making it more potent and shelf-stable.

Key conversion: 1 fresh lemongrass stalk = 1 teaspoon dried lemongrass powder. For best results, add dried lemongrass early in cooking to allow full flavor development, while fresh stalks should be removed before serving due to their tough fibers.

Why Home Cooks Love Lemongrass Spice

• Instant flavor boost: Adds authentic citrus notes without lemon's acidity
• Versatile substitution: Perfect when fresh lemongrass isn't available
• Long shelf life: Stays fresh for up to 2 years when stored properly
• Better infusion: Dried form releases flavors more quickly in dishes

Global Culinary Uses: Beyond Thai Food

Lemongrass spice shines across global cuisines with specific applications you can try today:

• Thai cuisine: Essential in Tom Yum soup (use 1 tsp dried per serving)
• Vietnamese pho: Adds complexity to broth (simmer with other spices)
• Caribbean jerk: Blends with allspice and scotch bonnet peppers
• Indian chai: Creates unique masala blends with cardamom and ginger
• West African stews: Balances rich peanut sauces with bright notes

Pro tip: For Caribbean jerk seasoning, combine 2 tsp dried lemongrass with 1 tbsp allspice, 1 tsp thyme, and ½ tsp cayenne for an authentic dry rub.

7 Practical Cooking Tips for Perfect Results

1. Use the right amount: Start with ¼ tsp per serving for subtle flavor, up to 1 tsp for bold citrus notes
2. Bloom in oil: Heat dried lemongrass in cooking oil for 30 seconds before adding other ingredients
3. Combine with fats: Works best in coconut milk, cream, or oil-based dishes for flavor absorption
4. Perfect for dry rubs: Mix with paprika and garlic powder for chicken or fish
5. Dessert applications: Add ⅛ tsp to shortbread or lemon bars for complex citrus flavor
6. Storage tip: Keep in airtight container away from light; discard when aroma fades
7. Revive old spice: Toast in dry pan for 1 minute to refresh flavor

Myths vs Facts: What You Need to Know

• Myth: Dried lemongrass has weaker flavor than fresh.
  Fact: Dried lemongrass is more concentrated—use less to avoid overpowering dishes.
• Myth: You can substitute lemon zest for lemongrass.
  Fact: Lemon zest provides acidity but lacks the herbal complexity; use ½ tsp lemon zest + ¼ tsp ginger as closest approximation.
• Myth: Lemongrass spice loses all nutritional value when dried.
  Fact: Drying concentrates certain compounds like citral while preserving most benefits.

Science-Backed Health Benefits of Lemongrass

Research indicates lemongrass contains citral (70-85% of essential oil), which may provide:

• Digestive support: A 2022 Journal of Ethnopharmacology study found lemongrass tea reduced bloating in 68% of participants
• Anti-inflammatory effects: Citral may help reduce inflammation markers according to a 2023 review in Frontiers in Pharmacology
• Antimicrobial properties: Effective against certain foodborne pathogens as shown in Food Chemistry studies
• Stress reduction: Aromatherapy studies show lemongrass scent may lower cortisol levels

Note: These benefits are associated with culinary use. Lemongrass should complement—not replace—medical treatment. Consult healthcare providers for health concerns.
