Ingredients for chinese pork and watercress soup
Star anise, ginger, and pork transform simple ingredients into aromatic Cantonese comfort.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Shoulder 🥩 | 1 ½ lb | Cut into 1-inch slices, bone-in preferred |
| Star Anise 🌟 | 2 whole | Whole pods for infusion |
| Fresh Ginger 🧅 | 2 tbsp | Finely grated, fresh preferred |
| Watercress 🌿 | 4 cups | Fresh, stems trimmed |
| Green Onions 🧅 | 3 whole | White and green parts separated |
| Garlic Cloves 🧄 | 4 cloves | Minced for broth |
| Low-Sodium Soy Sauce 🍶 | 2 tbsp | For umami depth |
| Sesame Oil 🫒 | 1 tsp | Toasted for aroma |
| Dried Shiitake Mushrooms 🍄 | 4 pieces | Rehydrated for broth |
| Cornstarch 🌾 | 1 tsp | For broth thickening |
| Water 💧 | 6 cups | For broth base |
| Salt 🧂 | 1 tsp | Adjust to taste |
| White Pepper 🌶️ | ½ tsp | Freshly ground |
The star anise and pork shoulder are your flavor anchors. Look for whole star anise pods at Asian markets—they infuse the broth with that signature sweetness. Pork shoulder stays tender when sliced thin, but don't skip the bone-in cut—it adds depth to the broth. Costco or local butchers often have the best prices for this cut. Fresh ginger is a must here; dried lacks that bright punch. If you can't find it, substitute 1 tbsp ginger juice, but trust me on the fresh version. The shiitake mushrooms? Rehydrate them first—soak in hot water for 20 minutes, then squeeze out excess liquid. That's where the umami magic happens.
No star anise? 1/2 tsp anise seeds work in a pinch, but the flavor won't be identical. Watercress wilting? Use baby spinach instead, but add it just 30 seconds before serving to keep it vibrant. Soy sauce substitute? Coconut aminos or tamari both work. The sesame oil is non-negotiable for that final aroma hit—toast it in a dry pan for 30 seconds before adding to the soup. Cornstarch can be swapped for arrowroot powder, but cornstarch gives that classic silky texture. And if you're feeling fancy, add a splash of Shaoxing wine when you deglaze the pot—game changer.
This soup tastes even better the next day—flavors meld like magic. Store in the fridge for 3-4 days or freeze for up to 3 months. Reheat gently on the stove, adding a splash of water to keep it silky. I always make double batches because it disappears so fast. Portion into containers for easy lunches—just add fresh watercress when reheating. The broth alone makes a great base for noodles or rice if you've got leftovers.

- One-Pot Magic: I swear by this recipe when I’m too tired to scrub a million bowls—just toss everything into one pot, simmer, and walk away. The pork shoulder practically falls apart on its own, so tender it melts like butter, while the star anise and ginger infuse the broth with that deep, aromatic warmth without any fuss.
- Pork Perfection: Between us, the pork shoulder here is chef’s kiss—crisp edges from the initial sear, then fall-apart tender after hours of slow simmering. The watercress adds this bright, peppery kick that cuts through the richness, like a little green hug in every spoonful. Honestly, I’ve made this soup for picky eaters, and even they ask for seconds.
- Lunchbox Hero: This soup is my go-to for meal prep because it actually tastes better the next day—yes, really. Pack it in thermoses for work or school lunches, and the flavors only deepen.

Step-by-step instructions for Chinese pork and watercress soup
Here's how to create a fragrant, silky-smooth pork and watercress soup with deep star anise notes.
🔥 Step 1: Prepare the Pork and Infuse the Broth
Cut the 1.5 lb pork shoulder into 1-inch slices—bone-in keeps it flavorful. In a large pot, combine the pork with the 6 cups water, 2 whole star anise, 2 tbsp finely grated fresh ginger, 4 cloves minced garlic, 4 pieces dried shiitake mushrooms, 1 tsp salt, and 0.5 tsp white pepper. Bring to a boil over high heat, then reduce to a simmer for 45 minutes. Skim off any foam that rises to the surface—this ensures a clear broth.
Here's the thing—star anise needs time to infuse its sweet, licorice-like aroma. After 45 minutes, check the pork for tenderness. It should be fork-tender but still hold its shape. If it's not quite there, simmer another 15-20 minutes. The broth should smell rich and aromatic, with the star anise's essence permeating every inch.
🍳 Step 2: Build the Umami Base
Strain the broth through a fine-mesh sieve into a clean pot, pressing gently on the solids to extract all the flavor. Return the broth to the pot and stir in the 2 tbsp low-sodium soy sauce. This adds that essential umami depth that defines Chinese soups. Bring the broth back to a gentle simmer, then reduce heat to low to maintain warmth.
While the broth heats, trim the stems from the 4 cups watercress and separate the 3 whole green onions into white and green parts. The white parts will cook in the broth, while the greens will garnish at the end. Here's where it gets fun—toss in the watercress and cook for just 2 minutes. Overcooking turns watercress bitter, so keep an eye on it. You want vibrant green leaves that wilt slightly but retain their bright color.
🥘 Step 3: Thicken and Finish with Sesame Oil
In a small bowl, whisk together the 1 tsp cornstarch with 2 tablespoons of the hot broth until smooth. Slowly pour this slurry into the simmering pot, stirring constantly. The broth will thicken noticeably within 1-2 minutes—this creates that silky, velvety texture we're after. Taste and adjust seasoning with more salt or soy sauce if needed. The soup should be savory but not salty.
Remove the pot from heat and stir in the 1 tsp toasted sesame oil. This adds a nutty aroma that elevates the entire dish. The oil should be toasted first—heat it in a small pan over low heat for 30 seconds until fragrant, then let it cool slightly before adding. This step is non-negotiable for that authentic restaurant-quality flavor.
🍽️ Step 4: Serve with Confidence
Ladle the hot soup into bowls, dividing the pork slices evenly. Garnish each serving with the reserved green onion whites (lightly sautéed for 30 seconds in a dry pan for extra flavor) and the green onion greens. The contrast of textures—tender pork, silky broth, and crisp watercress—is what makes this soup so special.
Serve immediately while steaming hot. The aroma alone will have everyone at the table anticipating that first sip. Each spoonful should deliver a perfect balance of rich pork, earthy watercress, and that delicate star anise perfume. This isn't just soup—it's comfort in a bowl, and it's exactly why this recipe delivers on that promised tenderness.
Pro Tips For Making Chinese Pork And Watercress Soup
- Parboil Pork First: Skip the raw pork plunge—parboil the shoulder in salted water for 10 minutes first. This guarantees even cooking later and keeps the meat from turning rubbery when it hits the soup’s simmer. I learned this the hard way after serving a batch where the center was still tough.
- Peel Ginger Roughly: Don’t waste time peeling ginger like an apple—just scrub it under water and slice off the rind with a knife. The slight texture adds depth, and you’ll save minutes. (Yes, even if you’re impatient like me.)
- Add Watercress Late: Toss in the watercress only in the last 3 minutes of cooking, or it’ll turn to mush. Crowd the pot too early, and you’ll end up with a sad, limp garnish instead of bright, crisp greens.
- Toast Star Anise: Dry-toast the whole star anise in a pan for 30 seconds before adding it to the broth—this unlocks its aroma. I was skeptical until I tried it; the soup now smells like a proper Chinese kitchen.
Flavor customization for this recipe
Spicy Kick Option
For those who love heat, add 1-2 slices of fresh red chili (like Thai bird's eye) when you strain the broth. Simmer them in for 10 minutes before removing. The chili will infuse the broth with subtle heat that lingers beautifully.
If you prefer a smoky kick, swap the chili for ½ tsp Sichuan peppercorns—toast them first in a dry pan for 30 seconds to release their aroma. 🌶️
Sweet & Tangy Twist
Brighten the soup with 1 tbsp Shaoxing wine when you deglaze the pot after removing the pork. The wine adds depth and a subtle sweetness that pairs perfectly with the star anise.
For extra tang, finish with 1 tsp rice vinegar per bowl—just a splash at the end to cut through the richness. Trust me, this balance is what makes the soup sing.
Herb-Infused Variation
Swap watercress for 2 cups fresh cilantro and 1 cup Thai basil at the end. The cilantro adds a bright, citrusy note while the basil brings earthy sweetness. For extra aroma, lightly bruise the herbs before adding them to the broth.
This variation is especially refreshing in summer when you want a lighter but still flavorful soup. 🌿
Creamy Velvety Version
For a richer texture, stir in ¼ cup coconut milk after thickening the broth. The creaminess balances the peppery watercress beautifully. For an even silkier finish, blend ½ cup of the broth with the coconut milk before adding it back to the pot.
This works surprisingly well and adds a luxurious touch without overpowering the pork's natural flavor.
Smoky Charred Pork
Take your pork to the next level by searing the slices in a hot pan until charred on both sides before adding them to the broth. The smoky depth from the charred edges adds complexity that pairs perfectly with the star anise.
For extra crispiness, broil the pork slices for 2-3 minutes after they've cooked in the broth—just watch them closely to avoid burning. This technique is inspired by my time in Charleston, where we love that smoky-sweet contrast.
Nutrition facts
Frequently asked questions
Can I use chicken instead of pork in this soup?
The traditional recipe calls for pork, but you can substitute with chicken breast or thigh cut into similar slices. Use 1.5 lbs boneless, skinless for best results. The flavor profile will be lighter, so add an extra 1 tsp soy sauce and 1/2 tsp white pepper to compensate. The broth will still infuse beautifully with star anise and ginger, though the texture will be slightly different.
How do I store and reheat leftovers?
Store in an airtight container in the fridge for 3-4 days or freeze for up to 3 months. To reheat, warm gently on the stove over medium-low heat—never microwave directly. Add 1/4 cup water per serving to restore the silky texture. The flavors actually deepen overnight, making leftovers even more comforting!
What if I can't find watercress?
Use baby spinach or bok choy as substitutes, but adjust cooking time. Watercress wilts in 2 minutes—spinach needs only 1 minute, while bok choy should cook for 3 minutes. For extra freshness, add 1/2 cup fresh mint leaves at the end. The peppery bite is key, so avoid overly mild greens like lettuce.
Can I make this soup in an Instant Pot?
Sauté the pork, ginger, garlic, and star anise in the pot first. Add all broth ingredients, then cook on high pressure for 20 minutes. Quick-release the pressure, then strain and thicken as directed. The Instant Pot version cooks 40% faster but requires careful monitoring to prevent overcooking the pork. The star anise will still infuse beautifully!
Why does my broth look cloudy?
Cloudy broth usually means proteins or starches weren't fully strained. After simmering, press the solids through a fine-mesh sieve with a spoon to extract all flavor. For extra clarity, chill the broth overnight—the fat will solidify on top, making it easy to remove. A slightly cloudy broth is still delicious, but a clear one indicates proper straining.
