Hot Sour Chicken Soup with Lotus Shoots

5.0 from 2 votes

Cambodian sour soups are built on a simple idea: the broth should wake up your palate without weighing you down. This one does exactly that. Tamarind brings the sourness, fish sauce adds a deep savory base, and a touch of sugar rounds everything into balance.

Lotus shoots are the quiet star here. They stay slightly crunchy in the hot broth, giving each spoonful a gentle textural contrast against the tender chicken. Lemongrass and kaffir lime leaves perfume the soup from the moment they hit the pot. It is a clean, fragrant bowl that comes together with basic pantry ingredients and one pot.

What You Need

The ingredients for this soup are straightforward. Fresh lemongrass and kaffir lime leaves do most of the aromatic work. If you can find frozen minced lemongrass, it works just as well. Boiled lotus shoots are usually sold packed and ready to use, which saves time. Tamarind juice provides the sour backbone, while fish sauce and sugar let you adjust the final balance to your taste.

Sweet basil and paddy rice herb go in at the very end, so their fragrance stays bright. The optional chili adds heat, but the soup is perfectly good without it.

Equipment

Soup pot: To sauté the aromatics and simmer the chicken, broth, and lotus shoots.
Cutting board: To safely cut the chicken, tomato, green onion, and chili.
Chef’s knife: To slice the garlic, chop the herbs, and prepare the vegetables.
Wooden spoon: To stir the ingredients gently without scratching the pot.

How to Make Hot Sour Chicken Soup with Lotus Shoots

Step 1: Toast the garlic

Heat the soup pot over medium heat. Add the oil. When the oil is hot, add the sliced garlic and sauté until it turns golden brown. Remove the toasted garlic from the oil with a slotted spoon and set it aside for the garnish.

Step 2: Brown the chicken with lemongrass

Add the minced lemongrass and the chicken pieces to the pot with the hot oil. Season with salt and black pepper. Stir and cook until the outside of the chicken is lightly browned.

Step 3: Simmer the broth

Pour in the water and add the kaffir lime leaves. Bring the liquid to a gentle simmer and cook until the chicken is tender.

Step 4: Balance the flavor

Stir in the tamarind juice, sugar, and fish sauce. Taste the broth. It should be sour first, then savory, with a mild sweetness behind it. Adjust any of the three seasonings if needed.

Step 5: Add the lotus shoots and tomato

Add the boiled lotus shoots and the tomato wedges. Stir and cook until the soup comes back to a gentle bubble. The lotus shoots just need to heat through; they should stay slightly crunchy.

Step 6: Finish with fresh herbs

Turn off the heat. Top the soup with the chopped green onion, sweet basil, paddy rice herb, and optional chili. Scatter the reserved toasted garlic over the top.

Cooking Tips

Taste before serving. The sour-sweet-salty balance is personal. If it needs more tang, add a little tamarind juice. If it needs more depth, add fish sauce. If it tastes too sharp, a pinch more sugar will soften it.
Do not overcook the lotus shoots. They are already boiled. They only need a minute or two in the hot broth to warm through and absorb some flavor.
Add the herbs off the heat. The residual warmth of the soup is enough to release their aroma without cooking away their freshness.

How to Serve

Ladle the soup into bowls while it is hot. Serve it with steamed jasmine rice on the side. The rice soaks up the broth and makes the meal more filling. A simple side of grilled fish or a fresh cucumber salad works well alongside it.

Recipe Notes

If you are using fresh tamarind instead of prepared tamarind juice, soak the pulp in a little hot water, mash it, and strain out the seeds before adding the liquid to the pot.

Frequently Asked Questions

What does this soup taste like?

It is sour and savory first, with a gentle sweetness. The lemongrass and kaffir lime leaves give it a citrusy aroma, and the lotus shoots add a light crunch.

Can I use chicken thighs instead of breast?

Yes. The recipe works with either cut. Thigh meat will give you a slightly richer broth. Adjust the simmering time so the chicken cooks through without drying out.

How should I store leftovers?

Keep the soup in a covered container in the refrigerator for up to three days. Reheat it gently on the stove. The lotus shoots will soften a little after storage, but the flavor will still be good.

Is this soup gluten-free?

The recipe as written uses fish sauce, which is generally gluten-free, but some brands may add wheat. Check the label on your fish sauce to confirm.

Final Thoughts

This soup is a good example of how Cambodian cooking builds flavor without clutter. A few aromatics, a clear broth, and a balance of sour, salty, and sweet do most of the work. The lotus shoots make it feel a little special, but they are easy to find and even easier to cook. Make a pot when you want something warm that still tastes clean and bright.
