Ingredients for best prawn

Fresh prawns, rich butter, and aromatic garlic—this buttery garlic prawn recipe delivers restaurant-quality results in record time.

The prawns are the star, so quality matters. Look for size 31/40 at your local seafood counter or Whole Foods—they’re consistently fresh. If using frozen, thaw them overnight in the fridge, never under running water. Costco often carries vacuum-sealed prawns that stay fresh longer. Avoid any with a strong fishy odor or slimy texture. For the butter, Plugrá or Land O’Lakes are reliable choices—stick with unsalted to control seasoning. The garlic should be firm, plump cloves with no sprouting; Lundberg organic is a great store-bought option.

No fresh parsley? Cilantro or chives work as a pinch-hitter, though parsley’s bright flavor is ideal. Short on heavy cream? Half-and-half or whole milk will work, but the sauce won’t be as luscious. The lemon juice can’t be substituted—its acidity brightens the dish. If you’re missing thyme, dried oregano at half the amount is a decent swap, though it lacks thyme’s earthy depth. For the olive oil, avoid strong, peppery varieties like Kalamata—they’ll overpower the delicate prawn flavor. A light, fruity oil keeps the dish balanced.

Store prawns in the coldest part of your fridge, wrapped in a damp paper towel, and use within 2 days for peak freshness. The garlic butter sauce keeps for 3 days in an airtight container, though it’s best used immediately. For leftovers, reheat gently in a skillet over low heat—microwaving makes it greasy. Freeze the sauce in 1-tbsp portions for quick garnishes later. The parsley stays fresh for 5 days if wrapped in a damp towel and sealed in a bag.

Step-by-step instructions for buttery garlic prawns

Here's the method that delivers restaurant-quality prawns with perfect texture and bold flavor.

Pat the 1.5 lb large prawns completely dry with paper towels. This step is crucial—wet prawns will steam instead of sear. Place them in a bowl and season generously with 1.5 tsp sea salt and 0.5 tsp ground black pepper, rubbing the seasoning into the flesh to ensure even coverage. Let them sit at room temperature for 10 minutes while you prepare the rest of the ingredients.

I always use kosher salt here because it dissolves more easily and distributes evenly. The prawns should look dry and slightly glistening from the seasoning, not wet. This preparation prevents them from sticking to the pan and ensures maximum crispiness when cooked.

Heat a large skillet over medium-high heat and add 1 tbsp extra-virgin olive oil. Once the oil shimmers, add half of the 0.5 cup unsalted butter (cold cubes) and let it melt completely, about 1 minute. Add the prawns in a single layer, leaving space between each piece to prevent crowding.

Cook undisturbed for 1-2 minutes per side until they develop a golden-brown crust. This is where the magic happens—the butter renders and creates a flavorful, crispy exterior while keeping the prawns tender inside. If the butter starts to brown too quickly, reduce the heat slightly to prevent burning. Remove the prawns to a plate and set aside, keeping them warm.

In the same skillet, reduce the heat to medium and add the remaining 0.5 cup unsalted butter. Once melted, add the 8 cloves garlic cloves and cook for 30 seconds until fragrant but not browned. Here's the thing—garlic burns fast, so keep an eye on it. Add the 2 tbsp lemon juice and 1 tsp lemon zest, stirring to combine. The lemon brightens the rich butter flavor and balances the dish.

Sprinkle in the 0.5 tsp dried thyme and cook for another 10 seconds, just enough to wake up the spices. Remove the skillet from heat and stir in the 0.25 cup heavy cream, letting it warm through but not boil. This step builds the sauce that will coat the prawns perfectly.

Return the prawns to the skillet and toss gently to coat them in the buttery garlic sauce. Cook for 30 seconds to heat through, ensuring the prawns are fully warmed and the sauce clings to their surfaces. The prawns should be opaque and tender, with a crispy exterior that's just slightly firm to the touch.

Remove from heat and stir in the 0.25 cup fresh parsley, reserving a few sprigs for garnish. Taste and adjust seasoning if needed—this is your chance to balance the dish. Serve immediately, garnished with the reserved parsley, over crusty bread or with your choice of sides. The prawns should be tender yet firm, with a rich, garlicky butter sauce that's creamy but not heavy.

Make-ahead tips for this dish

Prep Ahead for Speed

Save time by prepping the garlic butter sauce up to 3 days ahead and storing it in an airtight container in the fridge. The flavors deepen overnight, and you’ll just need to reheat it gently in a skillet over low heat before tossing in the prawns.

I like to make a double batch—I use half for the recipe and freeze the rest in 1-tbsp portions for quick garnishes later. 🧈

Thawing Frozen Prawns

If using frozen prawns, thaw them overnight in the fridge (never under running water—they’ll turn rubbery). Place them in a colander and rinse briefly with cold water to remove any ice crystals.

Pat them very dry with paper towels before seasoning, as any moisture will prevent proper searing. I’ve found Costco’s vacuum-sealed prawns thaw beautifully this way. 🦐

Make-Ahead Prawns

Cook the prawns completely up to 2 days ahead and store them in the fridge. Reheat gently in a skillet with a splash of water or butter over low heat for 1-2 minutes until warmed through.

The sauce will separate slightly, so toss it back in the skillet with a little heavy cream to restore its richness. Serve with fresh sides like a lemon-herb quinoa or garlic sautéed spinach. ⏰

Freezing for Later

You can freeze the cooked prawns and sauce together for up to 1 month, but the texture won’t be as perfect. Thaw them in the fridge overnight, then reheat in a skillet over low heat with a splash of water to revive the sauce.

I recommend freezing them uncooked instead—just thaw and cook fresh for the best results. 💫

Sauce-Only Prep

Make the garlic butter sauce ahead and store it separately. When ready to cook, sear the prawns fresh and toss them in the pre-made sauce for 30 seconds to heat through.

This works great for meal prep—store the sauce in 1-tbsp portions in ice cube trays, then transfer to a freezer bag. Pop one out whenever you need a quick flavor boost! 🍋

Garnish Prep

Chop the fresh parsley and store it in an airtight container with a damp paper towel to keep it crisp. The zest and juice from 1 lemon can also be prepped ahead and stored in a small jar in the fridge for up to 5 days.

This way, you’ll have all your garnishes ready when you’re ready to plate. A little lemon zest goes a long way in brightening up the dish! 🌿
