  • Garlic cloves: minced garlic infuses the butter with aromatic warmth use fresh cloves for best flavor
  • Fresh parsley: adds bright herbal notes and freshness flat-leaf parsley is preferable for better texture
  • Fresh thyme: earthy and slightly minty complements the seafood beautifully
  • Lemon: provides zesty acidity that cuts through the richness of butter and enhances the langoustine taste
  • White wine: adds subtle depth and acidity to the sauce choose a dry white like Sauvignon Blanc or Pinot Grigio
  • Red pepper flakes: mild heat that balances the rich butter keep it light to avoid overpowering
  • Salt and pepper: to taste essential for seasoning and highlighting the natural flavors

Instructions

Slicing the Langoustine:
Using clean kitchen scissors carefully split each langoustine lengthwise down the middle to expose the meat while leaving the shell attached. This allows the garlic butter to penetrate and helps the langoustine cook evenly.
Preparing the Garlic Butter:
In a small pan melt the butter over low heat to prevent burning. Add the minced garlic and red pepper flakes cooking gently until the garlic is fragrant but not browned about 2 to 3 minutes. This step infuses the butter with those deep warm flavors.
Brushing and Cooking the Langoustine:
Generously brush the prepared garlic butter onto the exposed langoustine meat to ensure every bite is flavorful. Place the langoustines on a grill pan or under the broiler. Cook for 3 to 4 minutes until the meat turns opaque and is cooked through but remains tender and juicy. Watch closely to avoid overcooking.
Making the Herb Lemon Sauce:
Return the pan with the leftover butter to medium heat adding the white wine. Let it simmer gently until the wine reduces slightly concentrating its flavor. Stir in the chopped fresh parsley and thyme then squeeze the juice of both lemons into the sauce. This sauce is bright herbaceous and perfect for drizzling.
Serving:
Pour the warm herb lemon butter sauce over the grilled langoustines and serve immediately while the flavors are fresh and the langoustine still warm.

The lemon and fresh herbs brighten the rich butter and seafood while the garlic and pepper flakes add a subtle kick. One of my favorite family memories is serving this dish outdoors on a warm summer night laughter and the sea breeze mixing with the delicious aroma.

Storage Tips

Langoustine is best eaten fresh but if you have leftovers store them in an airtight container in the refrigerator for up to 24 hours. Reheat gently in a low oven or covered pan to keep the meat tender and avoid drying out. The sauce can separate when stored but giving it a quick whisk helps bring it back together.

Ingredient Substitutions

If you cannot find langoustine large shrimp or small lobster tails can be a good substitute though the texture and sweetness will differ slightly. Unsalted European butter works nicely if you cannot locate the French butter. If you dislike red pepper flakes omit them or replace with a small pinch of smoked paprika for a different depth of flavor.

Serving Suggestions

Serve the garlic butter langoustine with a wedge of lemon and a side of garlic bread for mopping up the sauce. A light mixed greens salad dressed simply with olive oil and lemon balances the richness perfectly. For a heartier meal creamy risotto or buttery new potatoes round out the plate beautifully.

Common Questions About the Recipe

→ What type of langoustine works best for this dish?

U7 wild langoustines or Norway lobsters are ideal due to their sweet, tender meat that cooks quickly and pairs perfectly with garlic butter and herbs.

→ Can I substitute regular butter for Isigny French butter?

Yes, unsalted regular butter can be used, but French butter provides a richer, creamier flavor that enhances the overall dish.

→ Why is the langoustine split lengthwise before cooking?

Splitting exposes the meat for even heat distribution and better absorption of the garlic butter, ensuring a more flavorful and evenly cooked result.

→ How do the herbs affect the flavor of the dish?

Fresh parsley and thyme add bright, aromatic notes that balance the butter's richness and complement the lemon's freshness for a complex flavor profile.

→ Is grilling or broiling better for cooking langoustine?

Both methods work well: grilling adds slight smokiness while broiling cooks quickly and evenly. Choose based on your equipment and taste preference.

→ Can I replace langoustine with another seafood?

Large shrimp or small lobster tails are suitable substitutes, though the texture and sweetness will vary slightly compared to langoustine.
