Breakfast & Brunch
This butter prawn recipe with egg floss transforms simple seafood into a restaurant-worthy dish that balances crispy prawns with delicate, silky yolk strands. The secret lies in perfectly searing the prawns in rich butter while maintaining their tender centers, then elevating them with a dramatic garnish of egg floss that adds both texture and visual appeal. I developed this technique after years of refining seafood dishes, ensuring every element comes together effortlessly yet impressively.
The prawns cook in just 5 minutes, their shells turning a golden brown while the flesh stays juicy and sweet. Meanwhile, the egg floss—made from whipped egg whites and sugar—creates thin, crisp strands that dissolve slightly on the tongue, adding a subtle sweetness that complements the buttery richness. This fusion of textures is what makes the dish truly special, turning a straightforward seafood preparation into something memorable.
What you'll end up with is a plate that looks as stunning as it tastes: crispy prawns resting on a bed of silky egg floss, their golden shells contrasting beautifully with the delicate strands. The butter sauce ties everything together, creating a harmonious balance of flavors that's both elegant and approachable. Serve it over steamed rice or with a side of roasted vegetables to complete the meal.
This recipe is perfect for brunch gatherings, weekend dinners, or even a special weeknight treat. The method is straightforward, but the result feels luxurious—proof that you don't need complicated techniques to create something extraordinary. Let's get cooking!
Ingredients for butter prawn recipe with egg floss
Nine essential ingredients transform humble prawns into restaurant-quality silk-and-crust perfection.
| Ingredient | Amount | Notes |
|---|---|---|
| Large Prawns (Shrimp) 🦐 | 1 ½ lb | Raw, deveined, shell-on, 31-40 count |
| Unsalted Butter 🧈 | ½ cup | European-style preferred, cold |
| Large Egg Whites 🥚 | 6 whole | Fresh, room temperature |
| Granulated Sugar 🍚 | ¼ cup | Superfine preferred for smooth floss |
| Fine Sea Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Freshly Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked preferred |
| Lemon Zest 🍋 | 1 tsp | From 1 organic lemon |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For finishing drizzle |
| Fresh Parsley 🌿 | ¼ cup | Chopped, for garnish |
| Steamed Jasmine Rice 🍚 | 2 cups | Cooked, for serving |
The prawns are non-negotiable—look for 31-40 count with shells intact for that signature crunch. Whole Foods or high-end seafood markets carry the best quality, but frozen thawed prawns work in a pinch if you can't find fresh. Pat them dry thoroughly before cooking, and let them sit at room temperature for 15 minutes—this ensures even searing. For butter, European-style (like Plugrá) has higher fat content, which gives superior browning and flavor. If you can't find it, regular unsalted butter works, but render it in a cold pan to avoid melting too quickly. The egg whites must be fresh—older whites won't whip properly for the floss.
No superfine sugar? Pulse regular granulated sugar in a food processor for 30 seconds to break it down. The floss technique is delicate—room temperature egg whites are critical, so take them out of the fridge 30 minutes before whipping. Substituting aquafaba (chickpea brine) at 1:1 ratio works for a vegan version, though texture differs slightly. For the butter, if you're concerned about dairy, avocado oil can replace half the butter, but the flavor will be less rich. The parsley isn't just garnish—it brightens the dish with acidity, so don't skip it. If you're short on time, frozen prawns thawed in cold water work, but pat them extra dry to prevent splattering.
Prawns keep best 1 day in the fridge if uncooked, but cook them immediately for peak texture. The butter sauce should be used within 2 hours of making, as it separates when chilled. Store cooked prawns in an airtight container for up to 2 days, but reheating dulls the crispiness—best served fresh. The egg whites lose volume after whipping, so prepare them last and keep them in the fridge until ready to use. For a make-ahead option, cook the prawns, store them separately, and whip the egg floss just before serving. This dish is all about presentation, so assemble plates right before eating.
Why You'll Love This Recipe
- Fewer Ingredients, Bigger Impact: I swear by this recipe because it’s that rare dish where the ingredients actually matter—just prawns, butter, sugar, and salt. No clutter, no stress, just pure, velvety richness from the egg floss melting into the shrimp. Honestly, I’ve tried fancier seafood dishes that needed 10 herbs and a marinade, but this? It’s foolproof.
- Butter-Sugar Crunch That Stops You: That crispy egg floss? It’s the star. The sugar caramelizes just enough to give it a delicate crunch, while the butter makes it silky-smooth—like biting into a tiny, golden cloud. Pair that with perfectly cooked prawns, and suddenly, a simple weeknight dinner feels like a restaurant-worthy bite.
- Weeknight Hero, Date Night Star: Between us, this is my go-to when I’m too tired to plan but still want something impressive. Toss in a handful of prawns, let the egg floss do its magic, and boom—you’ve got a dish that works for lazy Tuesday dinners or when I’m trying to impress someone special. (Yes, even on a Tuesday night.)
Step-by-step instructions for butter prawns with egg floss
Master the art of balancing crispy prawns with delicate egg floss in this refined technique.
Prepare the Prawns for Perfect Crispiness
Pat the 1.5 lb large prawns (shrimp) completely dry with paper towels—this is critical for achieving that signature crispy exterior. I like to make a shallow cut along the back of each prawn to ensure even cooking and prevent curling. Arrange them on a plate and let them sit at room temperature for 15 minutes before cooking.
In a small bowl, mix 1.5 tsp fine sea salt, 0.5 tsp freshly ground black pepper, and 1 tsp lemon zest. Gently toss the prawns in this seasoning, making sure each one is evenly coated. The lemon zest adds a bright contrast to the rich butter flavor, while the salt enhances the natural sweetness of the prawns. Let them rest for another 5 minutes to allow the seasoning to adhere fully.
Create the Egg Floss Mixture
In a heatproof bowl, combine the 6 whole large egg whites and 0.25 cup granulated sugar. Place this bowl over a pot of simmering water, ensuring the bottom of the bowl doesn't touch the water—this creates a gentle, even heat. Whisk continuously for 5-7 minutes until the mixture becomes thick, pale, and triples in volume. You'll know it's ready when you can draw a figure-eight with the whisk and have the strands hold their shape.
Here's the thing—this step requires patience. If you rush it, the floss will be grainy or break apart. The sugar needs to fully dissolve and the proteins to fully denature for that silky, cloud-like texture. Keep whisking until you can lift the whisk and have the mixture form soft peaks that slowly dissolve back into the bowl.
Cook the Prawns in Butter
Heat 0.5 cup unsalted butter in a large skillet over medium-high heat until it foams but doesn't brown. Add the seasoned prawns in a single layer, being careful not to overcrowd the pan. Cook for 2-3 minutes per side until the shells turn opaque and the prawns release easily from the pan. The butter should be bubbling gently around the prawns, creating a golden, glossy finish.
Remove the prawns to a warm plate and tent loosely with foil to keep them warm. Leave the butter in the pan—those browned bits are pure flavor. Reduce the heat to medium-low and carefully pour in 1 tbsp extra-virgin olive oil, swirling to combine. This prevents the butter from burning while you prepare the final presentation.
Assemble the Dish with Egg Floss
Return the prawns to the skillet and spoon the egg floss mixture over them in a gentle stream. The floss should cascade down like a waterfall, coating the prawns completely. Work quickly but carefully—egg floss hardens almost instantly when it hits the hot prawns. Tilt the pan slightly to ensure even distribution, and let it set for 30-45 seconds until the floss forms a delicate, lace-like crust.
Garnish immediately with 0.25 cup chopped fresh parsley and serve over 2 cups steamed jasmine rice. The contrast between the crispy prawns, silky egg floss, and fragrant rice creates a harmonious balance of textures and temperatures. Each bite should deliver that perfect combination of buttery richness, delicate sweetness, and satisfying crunch.
Pro Tips For Making Butter Prawn Recipe With Egg Floss
- Pat Prawns Dry: Wipe them down with paper towels before cooking—wet shells steam instead of sear, and you’ll lose that crispy butter crust you’re working for. I used to skip this, and my prawns always ended up greasy instead of golden.
- Whip Egg Whites Cold: Chill your mixing bowl and beaters for 10 minutes first, then whip the egg whites to stiff peaks. Warmth makes them gummy, and you’ll end up with sad, flat floss instead of light, airy strands.
- Salt Butter Generously: Taste the melted butter before adding prawns—it should be noticeably salty. Unsalted butter is a blank slate, and if you’re balancing flavors later, you’ll end up guessing. Trust me, your prawns won’t be sorry.
- Cook Prawns in Batches: Crowd the pan, and they’ll steam instead of sizzle. Two prawns per side in a hot pan guarantees a perfect sear every time—no flipping into a sad, greasy mess. (Yes, even if you’re impatient like me.)
Make-ahead tips for this butter prawn recipe with egg floss
Prawn Prep Ahead
Pat and season the prawns up to 24 hours ahead—store them uncovered in the fridge to keep them dry. The seasoning will cling better after resting, and you'll avoid last-minute prep stress. I like to portion them into single-serving containers with a sprinkle of salt and pepper so they're ready to hit the pan immediately. 🦐
Egg Floss Timing
Whip the egg whites and sugar just before serving—they lose volume when stored, even in the fridge. But you can prepare the dry ingredients (sugar measured, egg whites separated) a day ahead and store them in airtight containers. Keep the whites at room temperature until ready to whip for perfect texture. 🥚
Butter Sauce Prep
Make the butter sauce 1 hour ahead and store it in a sealed jar in the fridge. Reheat gently over low heat or in a 50% power microwave for 20 seconds, stirring until smooth. The butter should be warm but not melted—this prevents the floss from turning grainy when reassembled. 🧈
Rice Ready Strategy
Cook the jasmine rice 2 hours ahead and store it in a sealed container with a damp paper towel to maintain moisture. Reheat covered in the microwave for 1 minute, then fluff with a fork. Warm rice absorbs flavors better and complements the prawns' buttery richness perfectly. 🍚
Garnish Prep
Chop the parsley and zest the lemon a day ahead—store them separately in airtight containers. The lemon zest loses potency when exposed to air, so keep it refrigerated until ready to use. Fresh parsley stays vibrant for 3 days this way, ready to brighten your dish at the last minute. 🌿

Frequently asked questions
Can I substitute frozen prawns in this recipe?
Yes, but thaw them properly first! Place frozen prawns in a sealed bag and submerge in cold water for 10-15 minutes. Pat them extra dry—any moisture will cause splattering and prevent crispiness. For best results, use prawns labeled "sustainably harvested" and avoid pre-cooked varieties, which won't achieve the same texture.
What if my egg floss doesn't whip properly?
Check your egg whites—they must be fresh and room temperature. If they're old or cold, they won't whip to stiff peaks. Use a clean, dry whisk or stand mixer (grease can prevent proper whipping). For extra insurance, add 1/8 tsp cream of tartar to stabilize the mixture. If all else fails, use aquafaba (chickpea brine) at a 1:1 ratio, though texture will differ slightly.
How do I prevent the prawns from curling during cooking?
Make a shallow 1/4-inch cut along the back of each prawn before seasoning—this prevents curling and ensures even cooking. Use a large, heavy skillet (like cast iron) to maintain stable heat. Cook prawns in a single layer and avoid moving them too soon. If they still curl, press gently with a spatula for 10 seconds per side during cooking.
Can I make this dish ahead of time?
Cook the prawns and butter sauce 1 day ahead, then store separately. Reheat the prawns in a 350°F oven for 5 minutes (they won't be as crispy). Whip the egg floss just before serving—it loses volume when stored. Assemble the dish last minute for the best texture contrast. For sides, cook rice 2 hours ahead and reheat covered.
What's the best way to serve this dish?
Pair with steamed jasmine rice or warm crusty bread to soak up the buttery sauce. For a complete meal, add roasted asparagus or a simple cucumber salad to balance the richness. Garnish with extra lemon wedges and chopped chives for brightness. Serve immediately—this dish is all about fresh presentation!
