Healthy Tom Yum Soup Recipe: Bright and Citrusy

A lighter, weeknight-friendly Tom Yum that still hits with lemongrass, lime, chile heat, and that addictive tangy broth.

Tom Yum is the soup I make when I want my taste buds to wake up and start paying rent. It is bright, citrusy, a little spicy, and somehow still cozy enough to eat in sweatpants. This version keeps things lighter and weeknight-realistic without losing the big Thai flavors that make Tom Yum so iconic.

We are building a clean, punchy broth with lemongrass, galangal (or ginger), lime, and chile, then piling in mushrooms and your choice of protein. No heavy coconut milk here, just a broth that tastes like you squeezed sunshine into a pot and told it to simmer.

Why It Works

  • Big flavor, lighter feel: A clear broth powered by aromatics and lime, not fat or sugar.
  • Fast but not flat: A short simmer extracts a lot of fragrance from lemongrass and galangal.
  • Flexible heat: Make it mild for kids or go full Thai-spicy for the brave.
  • Protein-friendly: Shrimp, chicken, tofu, or a mix all work.
  • Restaurant vibes at home: Fish sauce plus lime juice is the salty-tangy “how is this so good” combo.

Storage Tips

Tom Yum is best fresh, but leftovers still slap if you store it smart.

How to store

  • Fridge: Cool, then refrigerate in an airtight container for up to 3 days.
  • Separate if possible: If you know you will have leftovers, store broth separately from shrimp or tofu so nothing turns rubbery.
  • Remove the big aromatics: Fish out lemongrass and makrut lime leaves before storing so the flavor does not get overly intense.

How to reheat

  • Warm gently on the stove over medium-low until steaming. Avoid a hard boil, especially with shrimp.
  • Add a fresh squeeze of lime after reheating to bring the soup back to life.

Freezing

  • You can freeze the broth only for up to 2 months. Mushrooms and shrimp get a little weird after freezing, so add them fresh when you reheat.

Common Questions

Is Tom Yum soup healthy?

This clear-broth Tom Yum is often lower in calories than creamy soups, packed with aromatics, and easy to load with vegetables and lean protein. The main thing to watch is sodium from fish sauce or broth. Use low-sodium stock and season gradually since fish sauce varies a lot by brand.

What if I cannot find makrut lime leaves?

No stress. (Makrut lime leaves are also sometimes labeled “kaffir” lime leaves at stores.) Use extra lime zest (about 1 teaspoon) and a little more lime juice at the end. The flavor will be slightly different, but still delicious and very Tom Yum-adjacent.

Can I make this without fish sauce?

Yes. Swap in low-sodium soy sauce or tamari, and consider adding a tiny pinch of sugar or a splash of rice vinegar to mimic the sweet-salty balance. It will not taste identical, but it will still taste great.

What is the difference between Tom Yum and Tom Kha?

Tom Yum is typically a clear, hot-and-sour soup. Tom Kha usually includes coconut milk, so it is creamier and softer around the edges. Both soups often use galangal (or ginger as a common substitute) along with lemongrass and lime.

How do I control the spice level?

Start with 1 chile (or 1 teaspoon chili paste), simmer, then taste. You can always add more heat at the end. If you overdo it, add a bit more broth and squeeze in extra lime to rebalance.

The first time I tried Tom Yum that really knocked me back, it tasted like someone turned the brightness dial all the way up and then added shrimp. Ever since, I have treated it like my kitchen reset button. When dinner needs to be quick but I refuse to be bored, this is what I make. It is also the soup that reminds me to taste as I go, because the difference between “pretty good” and “why am I standing over the pot drinking broth” is usually one more squeeze of lime and a little confidence with the fish sauce.
