What Makes This Recipe Special

- Using both the white and green parts of the green onions separately ensures that you get aromatic fragrance from the whites and fresh, vibrant color from the greens.
- Adding sesame oil and lemon juice at the very end brightens the dish and cuts through the richness, preventing the prawns from tasting heavy or overcooked.
- Roasted cashews add a subtle, toasty crunch that contrasts beautifully with the silky prawns and glossy sauce, elevating the texture without overpowering the dish.
Ingredients
12 largeprawns (about 1 pound), peeled and deveined
1 stalkof green onions, white and green parts separated
2 clovesof garlic, minced
1 tablespoonof vegetarian oyster sauce (gluten free)
1 tablespoonof sweet chili sauce
1 teaspoonof chili crisp
1 tablespoonof fresh lemon juice
2 teaspoonsof sesame oil
Handful of roasted cashews (optional)
Rice and sautéed vegetables for serving
Instructions
1
Peel and devein the prawns if not already done. Finely chop the white part of the green onions and set aside. Slice the green part diagonally into thin strips for garnish. Mince the garlic cloves.
2
Heat a pan over medium-high heat. Once hot, add a little oil.
3
Add the white parts of the green onions and garlic to the pan and sauté for about 1-2 minutes until fragrant.
4
Add the prawns to the pan in a single layer. Cook for 2-3 minutes on one side until they start to turn pink, then flip them over and cook for another 2-3 minutes until fully cooked through.
5
Add the vegetarian oyster sauce, sweet chili sauce, and chili crisp. Let it cook for 2 minutes until the mixture is sticky and glossy.
6
Add the sesame oil and lemon juice to the pan. If using cashews, add them at this stage. Be careful not to overcook, as prawns can become tough.
7
Once the prawns are cooked, garnish with the sliced green parts of the green onions. Serve hot alongside rice and sautéed vegetables. Adjust the amount of chili crisp for spiciness as preferred.
Essential Tips
Prep the prawns first
Prawns cook quickly, so have them peeled, deveined, and patted dry before you start stirring. This ensures even cooking and prevents overcrowding the pan, which can make them steam instead of sear.
High heat is key
Use a well-seasoned wok or a cast-iron skillet over medium-high to high heat. This creates the perfect Maillard reaction on the prawns, giving them a slight caramelized edge while keeping the inside tender.
Don't skip the aromatics
Sautéing the white parts of the green onions and garlic until fragrant releases their essential oils, which infuse the entire dish with a fragrant base before the prawns even hit the pan.
Sauce timing matters
Add the sauces after the prawns have turned pink but before they're fully cooked. This allows the sauces to coat and glaze the prawns, creating that coveted sticky, glossy finish without drying them out.
Freshness of citrus
Use fresh lemon juice instead of bottled. The bright acidity will cut through the richness of the sauces and prawns, balancing the dish and enhancing the overall flavor profile.
Smart Swaps & Variations
Mild and nutty
Swap the chili crisp for 1 teaspoon of smoked paprika and reduce the sweet chili sauce to 1 teaspoon for a subtler, smokier flavor.
Extra spicy
Increase the chili crisp to 1.5 teaspoons or add a pinch of cayenne pepper to the sauce mixture for a fiery kick.
No cashews
Replace cashews with 2 tablespoons of toasted peanuts or almonds for a different but equally satisfying crunch.
Vegetable-packed
Add 1 cup of sliced bell peppers or sugar snap peas to the pan along with the prawns for extra color and texture.
Sauce swap
Use 1 tablespoon of hoisin sauce instead of vegetarian oyster sauce for a sweeter, slightly tangy flavor profile.
What to Serve With This
- Steamed jasmine rice or garlic-fried rice to soak up the spicy-sweet sauce.
- Quick-pickled cucumbers or a simple Asian slaw for a refreshing crunch.
- A cold light beer or a chilled lychee spritz to balance the heat.
- Steamed bok choy or gai lan (Chinese broccoli) for a hearty, veggie-packed meal.
Storage & Reheating
Storage
Store leftovers in an airtight container in the refrigerator for up to 2 days. The prawns will absorb the sauce and become slightly denser, but the flavors will remain vibrant.
Reheating
Reheat gently in a skillet over low heat with a splash of water or broth to prevent drying. Avoid using the microwave, as it can make the prawns rubbery and the sauce overly concentrated.
Expert Chef Tips
- For extra depth, toast the cashews in a dry pan for 2 minutes before adding them to the stir-fry. This enhances their nuttiness and prevents them from absorbing too much sauce.
- Use a pair of tongs to flip the prawns instead of a spatula. This gives you better control and helps prevent the prawns from curling up too tightly, ensuring even cooking.
- If your prawns are large (16/20 count), butterfly them by slicing along the belly before cooking. This reduces the cooking time and ensures they stay plump and juicy throughout.
Equipment You’ll Need
- Wok or large cast-iron skillet

Frequently Asked Questions
Can I use frozen prawns?
Yes, but thaw them completely and pat them very dry with paper towels before cooking. Excess moisture will steam the prawns instead of searing them, leading to a less desirable texture.
What's the best way to devein prawns?
Use a sharp paring knife to make a shallow cut along the belly, then pull out the dark vein with the tip of the knife or your finger. Rinse under cold water to remove any residue.
Can I make this dish ahead of time?
This dish is best served fresh, but you can prep the ingredients up to a day ahead. Store the prawns, chopped aromatics, and sauces separately in the fridge. Cook everything fresh when ready to serve.
Is there a gluten-free substitute for vegetarian oyster sauce?
Yes, coconut aminos or a gluten-free oyster sauce alternative work well. Just ensure the sweet chili sauce is also gluten-free if that's a concern.
How do I know when the prawns are cooked?
Prawns turn from translucent to opaque pink when fully cooked. They should feel firm to the touch but still slightly springy. Overcooking will make them tough and rubbery, so remove them from the pan as soon as they're done.
Can I use shrimp instead of prawns?
Absolutely! Shrimp work well in this dish, though they may cook slightly faster due to their smaller size. Adjust the cooking time to 1-2 minutes per side.
What's the best oil to use for stir-frying?
Neutral oils like avocado, grapeseed, or peanut oil work best for stir-frying as they have a high smoke point. Avoid olive oil, which can burn at high temperatures.
Can I add other vegetables to the stir-fry?
Yes! Add hearty vegetables like broccoli, carrots, or mushrooms at the same time as the prawns. For leafy greens like spinach or bok choy, add them at the very end to wilt slightly in the residual heat.
