Cantonese Poached Shrimp with Ginger-Scallion Oil

Wok hei is everything. Every family has their version of poached shrimp, and every family thinks theirs is best. Mine is pretty great, I'll admit. This is the kind of Chinese home cooking that doesn't show off. It doesn't need to. My mother-in-law taught me, and she was right — fresh is non-negotiable. When you respect these basics, the food takes care of itself.

Ingredients

For Poaching the Shrimp

1½ pounds large shrimp (16-20 count), peeled and deveined, tails intact

4 cups chicken stock or light seafood broth

3 tablespoons Shaoxing rice wine

4 slices fresh ginger (about ¼ inch thick, unpeeled), slightly smashed with the side of a knife

3 scallions, white and light green parts only, cut into 2-inch lengths

2 whole star anise pods

1 bay leaf

6-8 whole Sichuan peppercorns or black peppercorns

1 teaspoon kosher salt

½ teaspoon white pepper powder

For the Ginger-Scallion Oil (Oil Infusion)

⅓ cup peanut oil or other neutral oil with high smoke point

4 scallions, white and light green parts, sliced into thin rounds (reserve dark green for garnish)

2 tablespoons fresh ginger, peeled and cut into thin julienne

3 cloves garlic, thinly sliced

1 Thai bird's eye chili or red chili, sliced thin (optional, for subtle heat)

½ teaspoon white pepper powder

½ teaspoon kosher salt

½ teaspoon sesame oil

1 teaspoon light soy sauce

For Finishing and Serving

3 scallions, dark green parts, thinly sliced on the bias

1 tablespoon fresh cilantro, roughly chopped (optional but traditional)

1 teaspoon white sesame seeds

Lime wedges for serving

Light soy sauce for drizzling

Equipment Needed

Large stockpot or Dutch oven with lid (at least 3-quart capacity)

Colander for draining shrimp

Slotted spoon or spider strainer for gentle removal of shrimp

Small saucepan for preparing the ginger-scallion oil

Sharp chef's knife for prep work

Cutting board

Vegetable knife or peeler for julienning ginger

Measuring cups and spoons

Tasting spoon

Shallow serving platter or individual bowls

Paper towels for drying shrimp

Wooden spoon for stirring

Fine-mesh strainer (optional, for straining oil if desired)

Instant-read thermometer (optional, to verify shrimp temperature)

Detailed Instructions

Step 1: Prepare the Shrimp (8 minutes)

Pat the peeled and deveined shrimp completely dry with paper towels. Moisture on the surface can interfere with proper cooking and presentation. Place the dried shrimp on a clean plate or paper towel.

If your shrimp are still partially frozen, thaw them in the refrigerator for at least 2 hours, or run under cold water for 10 minutes. Cold shrimp will lower the poaching liquid temperature, affecting cooking time.

Inspect each shrimp to ensure no vein remains. Run your finger along the back where the vein was—if you feel any dark material, create a shallow slit with the tip of your knife and remove it. This ensures the most delicate eating experience.

Keep the shrimp chilled in the refrigerator until immediately before cooking. Shrimp are best when very fresh and haven't been sitting at room temperature.

Step 2: Build the Poaching Broth (5 minutes)

Pour the chicken stock into a large stockpot and bring to a boil over high heat.

Add the Shaoxing wine, allowing the alcohol to burn off for 30 seconds. You should smell the aromatic note of the wine.

Smash the ginger slices gently with the flat side of your knife to slightly crush them, releasing their oils and aroma. Add them to the boiling liquid along with the scallion whites and light green parts.

Add the whole star anise, bay leaf, and Sichuan peppercorns. These aromatics will infuse the broth with subtle spice and warmth.

Season with kosher salt and white pepper powder. Taste the broth—it should taste pleasantly seasoned but not overly salty, as the shrimp will absorb some of the liquid's flavors. Adjust if necessary.

Reduce heat to medium-high and let the broth simmer for 2 minutes to allow all flavors to meld. You should smell a wonderful aroma of ginger, star anise, and wine.

Step 3: Poach the Shrimp (6-8 minutes)

Once the broth is at a gentle, rolling simmer (not a vigorous boil—violent boiling will make shrimp tough), carefully add the cold shrimp. They should immediately sink and then begin to float as they cook.

Set a timer for exactly 5 minutes for large shrimp (16-20 count). This timing is crucial—every 30 seconds of overcooking results in noticeably tougher texture. Smaller shrimp (26-30 count) need only 3-4 minutes; jumbo shrimp (13-15 count) may need 6-7 minutes.

Do not stir the shrimp while they poach. They will cook evenly without agitation. Gentle poaching is the essence of this technique.

After 4 minutes, observe the shrimp carefully. They should be transitioning from gray-blue to pink, curling slightly into C-shapes. As they approach doneness, they'll form tighter C-shapes or even O-shapes.

At the 5-minute mark, use a slotted spoon to remove one shrimp and cut it in half lengthwise. The interior should be completely opaque white with a faint line of pink or orange—no translucent gray in the center. If still slightly translucent, cook for one more minute and test again.

When perfectly cooked, immediately remove all shrimp with a slotted spoon and transfer to a colander. Place the colander over a bowl (you can save some of the cooking liquid for sauce if desired). Discard the aromatics in the broth or strain for other uses.

Step 4: Prepare the Ginger-Scallion Oil (3 minutes)

While the shrimp poach, prepare the ginger-scallion oil, which should be warm and aromatic when the shrimp finish cooking.

Heat the peanut oil in a small saucepan over medium heat until a thin wisp of smoke just begins to appear, approximately 350°F. The oil should be hot but not smoking—this is the ideal temperature for infusing aromatics without burning them.

Carefully add the sliced scallion whites and the julienned ginger to the hot oil. You should immediately hear a gentle sizzle and smell an incredible aroma of ginger. Be careful of splattering oil.

If using the optional chili, add it now along with the garlic. Cook for 30-45 seconds, stirring gently, until the aromatics are fragrant and the edges of the ginger are just beginning to curl and brown slightly.

Remove from heat immediately. The residual heat will continue cooking the aromatics for a few seconds. Add the white pepper powder, kosher salt, and sesame oil.

Stir in the light soy sauce. Taste the oil—it should be aromatic, slightly nutty from the sesame, and savory from the soy sauce. The ginger should taste warm and fresh, not burnt or bitter. If it tastes burnt, you've cooked too long; next time, watch more carefully for the moment to remove from heat.

Step 5: Plate and Serve (3 minutes)

Arrange the poached shrimp in a shallow serving platter or divide among individual bowls. You can arrange them in a circle or pile them casually—the presentation should look elegant but natural.

Taste the warm ginger-scallion oil one final time. If desired, you can strain it through a fine-mesh strainer to remove some of the solids and create a silkier consistency, though leaving the solids makes for a more rustic, authentic presentation.

Carefully pour the warm ginger-scallion oil over the shrimp, distributing the aromatics evenly. The heat of the oil will briefly warm the just-cooked shrimp without overcooking them. You should hear a satisfying sizzle as the hot oil meets the shrimp.

Garnish generously with the reserved dark green scallion slices, white sesame seeds, and cilantro if using. The green color provides visual interest and fresh flavor contrast.

Drizzle lightly with additional light soy sauce—just a small amount for extra umami depth.

Serve immediately while the oil is still warm and aromatic. Provide lime wedges on the side for squeezing over the shrimp, which brightens all the flavors.

6 Expert Tips

Temperature is Paramount: The difference between perfectly tender shrimp and tough shrimp is literally 30 seconds. Use a timer religiously and remove one test shrimp to verify doneness before removing all of them. Cold shrimp sizes vary; 5 minutes is a guideline for large (16-20 count) shrimp—adjust based on your specific size.

Don't Skip the Drying Step: Shrimp fresh from the package contain surface moisture. Pat them completely dry with paper towels before adding to the broth. This small step prevents dilution of the cooking liquid and helps achieve the most delicate texture.

Ginger-Scallion Oil Temperature is Critical: The oil must be hot enough (around 350°F) to create an audible sizzle when it hits the shrimp—this is when the aromatic infusion happens. If the oil is too cool, it won't properly bloom the aromatics; too hot, and it will burn them. Watch for a thin wisp of smoke just beginning to appear in the pan as the signal to add aromatics.

Star Anise is Non-Negotiable: While it might seem optional, star anise is the signature aromatic of Cantonese poaching broths. Its subtle licorice note, combined with ginger and scallion, creates the classic Cantonese flavor profile. Don't skip it if possible.

Shrimp Size Consistency: Use shrimp of uniform size so they cook evenly. If you have a mix of sizes, cook the larger ones first, remove them, then cook the smaller ones separately for the correct timing.

Gentle Handling Throughout: From drying to removing the shrimp, handle them gently to preserve their delicate texture and appearance. Use a slotted spoon rather than tongs, which can damage the flesh or stress the shrimp.

5 Variations

Shanghai-Style with Brown Sauce: After poaching, drain the shrimp and prepare a thickened brown sauce by combining 3 tablespoons soy sauce, 1 tablespoon oyster sauce, ½ cup of the reserved cooking liquid, 1 teaspoon sugar, and 1 teaspoon cornstarch mixed with 1 tablespoon cold water. Heat until thickened, then pour over the shrimp. Shanghai cuisine favors rich, silky sauces.

Sichuan Pepper-Numbing Version: Increase Sichuan peppercorns to 1 tablespoon in the poaching broth and crush them lightly to release more oils. Finish with a chili oil made by infusing 4 tablespoons peanut oil with 4 dried red chilies, 1 tablespoon of freshly ground Sichuan peppercorns, and 1 tablespoon of chili flakes. The result is the distinctive numbing and spicy sensation (ma la) that defines Sichuan cuisine.

Hunan-Style Spicy Version: Add 2-3 whole dried chilies and 1 tablespoon of hot chili paste (doubanjiang) to the poaching liquid. Finish with a hot ginger-scallion oil that includes 2 teaspoons of chili flakes. Hunan cooking emphasizes bold, fiery heat and complex spice.

Light Soy Sauce and White Vinegar Version: Create a lighter glaze by mixing ½ cup of the reserved poaching liquid with 2 tablespoons light soy sauce, 1 tablespoon rice vinegar, and ½ teaspoon white sugar. Gently warm this and pour over the shrimp instead of the oil infusion. This creates a more delicate, brothy finish and is popular in coastal regions.

Winter Melon and Shrimp Poaching: Add ½ pound of diced winter melon to the poaching broth in the last 3 minutes of cooking the shrimp. The melon absorbs the aromatic broth and becomes creamy. Serve the shrimp over the melon with the ginger-scallion oil. This variation is particularly popular in Cantonese summer and winter preparations.

Storage Instructions

Refrigerator: Poached shrimp can be stored in an airtight container with some of the cooking liquid for up to 3 days. Store the ginger-scallion oil separately. To serve, gently reheat the shrimp in a small saucepan over medium heat with a splash of the cooking liquid until just warmed through (do not boil), then drizzle with freshly made ginger-scallion oil. Freezer: Cooked shrimp can be frozen for up to 2 months. Drain completely and store in a freezer-safe container. The texture will become slightly less delicate after freezing. Thaw overnight in the refrigerator before reheating. Do Not Refrigerate Before Serving: Unlike some dishes, this preparation is best enjoyed within 30 minutes of cooking, while the shrimp are still warm and the aroma is most fragrant. If you must make ahead, prepare only the poaching broth and aromatics, then cook the shrimp just before serving. Reheating: The best method is gentle reheating in a small amount of the cooking liquid over medium heat. Microwaving can create tough shrimp; avoid if possible.

Serving Suggestions

With Jasmine Rice: Serve the poached shrimp alongside fluffy jasmine rice with a light drizzle of the cooking liquid or ginger oil poured over the rice for absorption of flavors.

As Part of Dim Sum: Serve in small portions as one course of a dim sum meal, alongside har gow (shrimp dumplings), siu mai, and other traditional preparations.

With Blanched Vegetables: Plate the shrimp atop blanched bok choy or water spinach (water convolvulus), which has absorbed the aromatics beautifully. Drizzle the ginger oil over both.

In a Light Noodle Soup: Add the poached shrimp to a simple chicken or vegetable broth with delicate rice noodles or egg noodles, fresh scallions, and cilantro for a aromatic light soup.

With Steamed Tofu: Serve alongside silken tofu cubes that have been steamed and dressed with the ginger-scallion oil. The contrast between tender shrimp and creamy tofu is classic Cantonese.

Cold Shrimp Salad: Chill the poached shrimp and toss with sliced cucumber, shredded jicama, fresh herbs, and a light sesame-vinegar dressing for a refreshing warm-weather preparation.

Frequently Asked Questions

Q: Can I use frozen shrimp? A: Yes, frozen shrimp work well for this recipe. Thaw them completely in the refrigerator overnight or under cold running water for 10 minutes. Pat them dry before adding to the broth. They'll cook perfectly as long as they reach room temperature before poaching. Q: What's the difference between Shaoxing wine and other rice wines? A: Shaoxing rice wine, from the Shaoxing region of China, has a distinctive fermented depth with slight sweetness. It's specifically used in Cantonese cooking to add complexity. If unavailable, dry sherry or sake are acceptable substitutes, though the flavor profile differs slightly. Don't use regular rice vinegar, which is too acidic. Q: Can I make the ginger-scallion oil in advance? A: Yes, you can make it up to 2 hours ahead and keep it warm in a small thermos or reheat it gently just before serving. However, it's best enjoyed fresh when the aromatics are most fragrant. If making more than 2 hours ahead, store at room temperature in a container and gently reheat over medium-low heat until warmed through and fragrant. Q: How do I prevent overcooking? A: Use a timer set for exactly 5 minutes (adjust for your shrimp size). Remove one test shrimp after 4 minutes to verify doneness, and don't rely on appearance alone. Even if all shrimp appear pink on the outside, they may still be slightly underdone internally. A quick internal check ensures perfect results. Q: Can I substitute the peanut oil? A: Yes, use vegetable oil, canola oil, or avocado oil—any neutral oil with a high smoke point (above 350°F). Avoid olive oil, which has a low smoke point and will become bitter. Sesame oil alone will burn at this temperature, though a small amount added at the end (as in this recipe) is fine.

Ingredient Substitution Guide

Whether you're working around dietary restrictions, allergies, or simply using what's available in your kitchen, these substitutions work well in this chinese preparation:

King oyster mushroom slices: Slice stems into coins for a meaty, seafood-like texture. Score the surface for better seasoning absorption.

Hearts of palm: Slice canned hearts of palm into rounds. They have a mild, slightly briny flavor that mimics shrimp surprisingly well.

Sea scallops: Pat very dry for a good sear. Scallops cook slightly slower than shrimp, so add 1-2 minutes per side.

White fish chunks: Cut cod or tilapia into shrimp-sized pieces. Handle gently to prevent breaking apart during cooking.

When substituting, always taste and adjust seasoning as you go. Different proteins and ingredients absorb and carry flavors differently, so what works perfectly with shrimp may need tweaking with your substitute.

Common Mistakes to Avoid

Even experienced cooks stumble with poached shrimp. Here are the pitfalls to watch for:

Cooking at too high a temperature: Ideal poaching temperature is 160-180°F. Use a thermometer rather than visual cues, as even small temperature increases change the result dramatically.

Letting the liquid boil: Poaching requires gentle heat with tiny bubbles barely breaking the surface. A rolling boil toughens proteins and creates a ragged texture.

Using too little liquid: Food should be fully submerged for even cooking. If pieces stick up above the liquid line, they cook unevenly and dry out on top.

Not seasoning the poaching liquid: The liquid is your chance to infuse flavor. Add aromatics, salt, acid, and herbs generously since only some flavor transfers to the food.

Overcooking by even a minute: Poached food goes from perfect to overdone quickly. Start checking early and remove from liquid immediately when done. It continues cooking in residual heat.

Avoiding these common errors will dramatically improve your results. The difference between good and great often comes down to these small details that many cooks overlook.

Make-Ahead and Meal Prep Tips

This recipe is excellent for meal preparation. Here's how to get the most out of your batch cooking:

Refrigerator storage: 1-2 days in an airtight container. Shrimp overcook in seconds when reheating. Toss into hot sauce or soup at the very last minute, or serve cold in salads and wraps.

Freezer storage: Up to 3 months (raw). Peel and devein shrimp in bulk, then freeze in single-recipe portions. This cuts weeknight prep time to almost nothing.

Batch cooking strategy: Buy frozen raw shrimp for the freshest meal prep results. Thaw only what you need by running under cold water for 5 minutes.

Reheating for Best Results

The biggest mistake in meal prep is aggressive reheating that overcooks the protein. Shrimp overcook in seconds when reheating. Toss into hot sauce or soup at the very last minute, or serve cold in salads and wraps. For packed lunches, consider bringing components separately and assembling fresh. The texture stays better when sauces and garnishes are added at eating time rather than stored together.

Seasonal Adaptations

Chinese culinary philosophy deeply respects seasonal eating. Spring calls for delicate greens like pea shoots and Chinese chives. Summer dishes feature cooling ingredients like cucumber, mung bean, and bitter melon to balance body heat. Autumn celebrates lotus root, taro, and persimmons alongside harvest moon traditions. Winter cooking emphasizes warming ingredients — ginger, lamb, and rich broths that nourish according to Traditional Chinese Medicine principles. Adapting this recipe to the seasons doesn't just improve flavor — it often reduces cost since in-season produce is more abundant and affordable. Visit your local farmers' market for the freshest seasonal ingredients that will elevate this dish.

Scaling This Recipe

Need to feed more people or cooking for just yourself? Here's how to adjust:

For doubling, use a larger vessel rather than cooking two batches when possible. Proteins cook more evenly in a single batch with proper spacing.

Seasoning does not scale linearly. When doubling, start with 1.5 times the seasoning and adjust to taste. When halving, use about 60% of the original amount.

If feeding a crowd, consider cooking components separately and assembling at serving time. This gives you more control and keeps textures intact.

When halving this recipe, keep cooking temperature the same but reduce time by about 25%. Less food means less thermal mass, so it heats through faster.

As a general rule, taste frequently when scaling. Your palate is the best guide for getting the balance right at any batch size.
