Low Sodium Tom Yum Soup Recipe
This low-sodium version of Tom Yum soup keeps all the incredible flavors of the original recipe but with a careful reduction in salt. By swapping out or adjusting a few key ingredients, we can enjoy the soup without compromising on flavor.
Ingredients Needed
Here’s what you’ll need to make your Low Sodium Tom Yum Soup. These ingredients create that famous punchy flavor, with some subtle tweaks to keep it low in sodium:
- Low-Sodium Broth – The base of your soup. You can use vegetable or chicken broth with minimal salt. Some stores carry specialized low-sodium options, but make sure to check the label.
- Lemongrass – A key ingredient in Tom Yum. Its citrusy fragrance will give your broth a fresh, zesty lift.
- Kaffir Lime Leaves – These leaves give the soup a distinct flavor, so don’t skip them! They’re bright, aromatic, and super refreshing.
- Galangal – Often confused with ginger, galangal has a milder, slightly spicy and piney taste, perfect for the soup base. If you can’t find galangal, ginger can work as a substitute, though it’s not quite the same.
- Fresh Thai Chilies – For that spice kick! Use more or less depending on your heat tolerance. If you’re looking for a milder version, remove the seeds.
- Mushrooms – Usually, straw mushrooms are used, but you can substitute with any mushrooms you like. They add a nice texture and earthy flavor.
- Shrimp (or Tofu) – Shrimp is the most traditional protein, but tofu works for a vegetarian option. Both are light and take on the flavors of the broth wonderfully.
- Lime Juice – Fresh lime juice is non-negotiable! It adds the necessary sourness that makes Tom Yum so distinctive.
- Fish Sauce (Low-Sodium) – This is where you can be a bit tricky. Regular fish sauce is incredibly salty, so go for a low-sodium version, or even try coconut aminos if you’re cutting back on sodium entirely.
- Coriander (Cilantro) – Fresh coriander adds that final touch of freshness to garnish and enhance the flavor.
- Optional Sweetener (Palm Sugar) – Tom Yum is a balance of sweet, sour, salty, and spicy. Palm sugar is a traditional ingredient, but a small amount of honey or regular sugar can also work.
Cooking Instructions
Now that we’ve gathered our ingredients, it’s time to bring them all together into a flavorful bowl of low-sodium goodness. Here’s how to make it:
-
Prepare The Broth
- Start by bringing your low-sodium broth to a simmer in a large pot. You want it to heat up slowly to develop all the flavors.
-
Add Aromatics
- Smash the lemongrass stalks with the back of your knife to release their oils, and add them to the pot.
- Tear up the kaffir lime leaves to release their fragrance and add them as well.
- Slice the galangal thinly and toss that in. If using ginger, slice it similarly.
-
Flavor Infusion
- Drop in the Thai chilies. You can crush them lightly if you want more heat, or leave them whole if you prefer a milder flavor.
- Stir the broth and let everything simmer for about 5-10 minutes, allowing the flavors to meld together.
-
Add Mushrooms And Protein
- Add the sliced mushrooms (straw mushrooms or your choice) and shrimp (or tofu) to the pot.
- Let everything cook for another 3-4 minutes. The shrimp should turn pink, or tofu should soften.
-
Finish The Broth
- Add the low-sodium fish sauce and lime juice to taste. You might find you want a little more lime juice for extra tang.
- Stir in a tiny amount of palm sugar or your sweetener of choice to balance the flavors. A teaspoon or so should be enough.
-
Serve
- Once everything’s cooked and the broth is fragrant, remove the soup from heat.
- Ladle the soup into bowls and garnish with fresh coriander. Serve immediately.
Ingredient Insights
- Lemongrass: Lemongrass is a powerhouse herb that not only provides flavor but also has medicinal benefits. It’s great for digestion and can also have antibacterial properties. It’s best when bruised or smashed, as this helps release its oils into the broth.
- Kaffir Lime Leaves: These leaves are iconic in Southeast Asian cooking. They impart a unique, almost floral fragrance. They’re not meant to be eaten, so always remove them before serving. A tip: If you don’t have access to fresh leaves, you can sometimes find dried ones at specialty stores.
- Galangal: A cousin to ginger, galangal is less fiery and more aromatic. It’s often used in Thai, Indonesian, and Malaysian dishes. If you can’t find it, ginger can serve as a substitute, but it won’t be quite as authentic.
- Low-Sodium Fish Sauce: Fish sauce is an integral part of Thai cooking. In this recipe, we use a low-sodium version, but it still adds depth and umami. Don’t be afraid to add a little more if you feel the flavor needs to pop.
Expert Tips
- Control the Heat: If you’re sensitive to spice, start with fewer chilies. You can always add more as the soup simmers.
- Herb Substitutions: Fresh Thai herbs can be hard to come by, so feel free to substitute dried herbs, though the flavor may not be as bright.
- Perfecting the Balance: Tom Yum is all about balancing sour, salty, sweet, and spicy. Taste the broth before serving and adjust the lime juice, fish sauce, and sweetener to your liking.
- Make It Ahead: The soup can be made in advance. In fact, the flavors will deepen if allowed to sit for a few hours. Just be sure to reheat it gently.
- Garnish Generously: Fresh cilantro is the perfect garnish, but don’t shy away from adding chili slices or extra lime wedges on the side for guests who like it extra zesty.
Recipe Variations
- Vegetarian Version: Skip the shrimp and use tofu, seitan, or tempeh as your protein of choice.
- Spicy and Sour Lovers: Add more lime juice for extra tang or extra chilies for more heat.
- Mushroom Lovers: Double the mushrooms for a richer, earthier version of the soup.
- Noodle Soup: For a more filling version, add rice noodles or glass noodles to the soup once it’s cooked. Let the noodles soak up the broth.
