Craving a soup that’s bright, herbal, and seriously warming? This listicle rounds up ten standout hot Asian lemongrass soups, from the classic Thai tom yum to lesser-known Vietnamese and Indonesian broths. Whether you’re a home cook looking for a weeknight dinner or a foodie hunting for your next favorite bowl, these recipes cover broths, noodles, and even a creamy coconut version.
Tom Yum Goong (Thai Hot & Sour Shrimp Soup)
The undisputed king of lemongrass soups, tom yum goong balances hot, sour, salty, and sweet with fresh galangal, kaffir lime leaves, bird’s eye chilies, and shrimp. The broth is typically clear and light, but you can add a splash of coconut milk for a creamy tom yum nam khon. Use fresh lemongrass—bruise the stalk to release its essential oils—and don’t skip the roasted chili paste (nam prik pao) for that deep, smoky note.
Vietnamese Lemongrass Chicken Noodle Soup (Pho Ga Sa Ot)
This is a fragrant twist on pho, where chicken is simmered with lemongrass, ginger, and star anise, then served over thin rice noodles. The lemongrass adds a citrusy brightness that cuts through the rich chicken fat, while fresh herbs like Thai basil and sawtooth coriander brighten each spoonful. It’s a comforting, low-effort soup that comes together in about an hour, perfect for a cold evening.
Thai Lemongrass Tofu Soup (Tom Yum Hed)
A vegetarian take on tom yum, this version swaps shrimp for firm tofu and adds straw mushrooms or oyster mushrooms for texture. The broth is just as punchy, with lemongrass, galangal, lime juice, and fish sauce (or soy sauce for a vegan option). Serve it with jasmine rice to soak up every last drop of the aromatic broth.
Indonesian Lemongrass Beef Soup (Soto Ayam with Serai)
Soto ayam is a turmeric-rich chicken soup, but adding lemongrass (serai) gives it a citrusy backbone that pairs beautifully with the earthy spices. This version includes shredded chicken, boiled eggs, and crispy shallots, often served with rice cakes (lontong) or vermicelli. The lemongrass is bruised and simmered whole, then removed before serving—its job is to perfume the broth, not to be eaten.
Lemongrass Miso Soup (Japanese Fusion)
This fusion soup combines classic Japanese miso with Thai lemongrass for a surprisingly harmonious bowl. Start with dashi, add sliced lemongrass and ginger, then whisk in white miso at the end to preserve its delicate flavor. Add silken tofu, wakame, and a handful of baby spinach for a light yet satisfying meal that’s ready in under twenty minutes.
Cambodian Lemongrass Chicken Soup (Samlor Korko)
This hearty, slightly bitter soup uses lemongrass as a base along with prahok (fermented fish paste) and a medley of vegetables like eggplant, long beans, and pumpkin. The lemongrass is pounded into a paste with turmeric and galangal, giving the broth a thick, rustic texture. It’s a less common find outside Cambodia, but it’s worth seeking out for its unique, earthy flavor profile.
Lemongrass Coconut Seafood Soup (Thai Tom Kha Talay)
Tom kha is the creamy cousin of tom yum, and this seafood version is a showstopper. Coconut milk mellows the heat of the chilies, while lemongrass, galangal, and lime leaves keep it bright and aromatic. Use a mix of shrimp, squid, and mussels, and serve with a wedge of lime to squeeze over the top—the acidity cuts through the richness beautifully.
Lemongrass Glass Noodle Soup (Yum Woon Sen)
While technically a salad, this dish is served warm and soupy in many Thai households. Glass noodles are tossed with a hot dressing of lime juice, fish sauce, sugar, and chilies, then mixed with ground pork, shrimp, and plenty of lemongrass and shallots. The heat from the freshly cooked meat wilts the herbs, making it a fragrant, spicy, and tangy one-bowl meal.
Lemongrass Pumpkin Soup (Thai Gaeng Liang)
This is a quick, vegetable-packed Thai soup that uses lemongrass as a subtle background note. Pumpkin or squash is simmered with shrimp paste, chilies, and a handful of leafy greens like water spinach or morning glory. The lemongrass is pounded with garlic and shallots into a rough paste, which thickens the broth slightly and infuses it with a gentle citrus aroma.
Lemongrass Hot and Sour Fish Soup (Canh Chua with Serai)
This Vietnamese sour soup is traditionally made with fish, pineapple, and tomatoes, but adding lemongrass elevates the flavor to another level. The lemongrass is sliced thin and simmered with tamarind paste, giving the broth a complex sweet-sour-savory profile. Serve it with steamed rice and a side of fresh herbs; the soup is meant to be eaten hot, with the lemongrass slices often left in the bowl for extra zing.
How to Choose
The best lemongrass soup for you depends on your time, taste, and protein preference. If you want a quick weeknight meal, go for the miso or glass noodle versions—they come together in under half an hour. For a richer, more indulgent bowl, choose a coconut-based tom kha or the Cambodian samlor korko. If you’re craving something light and classic, start with tom yum goong or the Vietnamese chicken pho. Also consider what you have on hand: fresh lemongrass is essential, but frozen or dried works in a pinch—just use more to compensate for lost potency.
Frequently Asked Questions
How do I prepare lemongrass for soup? Trim the root end and the top green leaves, then peel away the tough outer layers. Bruise the stalk with the side of a knife to release oils, then cut into two-inch pieces for simmering or slice thinly for eating.
Can I use lemongrass paste instead of fresh stalks? Yes, but the flavor will be less bright and more concentrated. Use about one teaspoon of paste per stalk, and add it early in cooking to mellow its raw edge.
Why is my lemongrass soup bitter? Bitterness often comes from overcooking the lemongrass, especially if you slice it too thin and it breaks down. Simmer it gently and remove large pieces before serving; also avoid using the dark green tops, which are woody and bitter.
Can I freeze lemongrass soup? Yes, but the texture of coconut milk can separate upon thawing. Reheat gently and whisk to recombine; for best results, freeze the broth without the protein or noodles, and add them fresh when reheating.
What can I substitute for lemongrass? Lemon zest plus a bit of ginger is the closest substitute, but it won’t have the same floral depth. Use about a teaspoon of zest and a thumb of ginger per stalk of lemongrass.
Is lemongrass soup healthy? Generally, yes—it’s low in calories, high in water, and packed with aromatic herbs that aid digestion. Watch the sodium if you use fish sauce or store-bought broth; you can always dilute with water.
