Spanish Cognac Shrimp with Garlic and Lime

Langostinos al coñac is a festive Spanish seafood appetizer made by quickly sautéing whole prawns with garlic and finishing them with aromatic Cognac or brandy. Leaving the shells and heads attached keeps the meat juicy while adding intense shellfish flavor to the olive oil and pan juices.

Fresh parsley and lime zest balance the richness with herbal and citrus notes, while an optional dried chile adds gentle heat. The recipe takes only a few minutes to cook, making it particularly useful for holiday meals when an impressive appetizer needs to reach the table quickly.

Ingredient Notes

Gambón prawns

Gambón is a large, meaty prawn commonly used in Spanish cooking. Choose whole raw prawns with firm flesh, intact shells, and a clean ocean aroma. Jumbo shell-on shrimp are a practical US alternative.

Cognac or brandy

Cognac gives the dish a rounded aroma with subtle fruit and oak notes. Spanish brandy works equally well, but avoid sweetened brandy-based liqueurs.

Garlic

Finely chopped garlic flavors the oil quickly. Cook it gently before adding the prawns so it becomes aromatic without scorching or developing bitterness.

Lime zest

Only the thin green outer layer is needed. Add it after cooking so its fresh citrus aroma remains noticeable and does not become bitter.

Dried red chile

The chile is optional and should provide background warmth rather than dominant heat. A small dried cayenne chile is a suitable substitute.

Expert Tips

• Dry the prawns thoroughly before adding them to the oil to reduce splattering and encourage quick, even searing.
• Use a skillet large enough to hold the prawns in one layer so they sauté instead of steaming.
• Watch the garlic closely because finely chopped pieces can change from golden to burned in seconds.
• Add the Cognac only after removing the skillet from the burner, and never pour it directly from the bottle near an open flame.
• Avoid overcooking the prawns; they should be opaque and lightly curved rather than tightly curled into circles.
• Add the lime zest only after removing the skillet from the heat to preserve its freshest aroma.

Serving Suggestions

Serve the prawns directly from the skillet or transfer them to a warmed serving platter with all the garlic and brandy-infused juices.

Offer finger bowls and a separate dish for the shells, since the prawns are traditionally peeled at the table.

Pair them with roasted peppers, marinated olives, or a crisp green salad as part of a Spanish appetizer spread.

Serve with a dry Spanish white wine, sparkling wine, or chilled fino sherry.

Storage and Reheating

Refrigerate leftover prawns and their cooking juices in an airtight container within 2 hours and use them within 2 days. Reheat gently in a covered skillet over low heat just until warmed through. Avoid prolonged reheating because the prawns can quickly become dry and rubbery. Freezing the cooked dish is not recommended, although uncooked frozen prawns may be thawed safely in the refrigerator before preparing the recipe.

Frequently Asked Questions

Can I make cognac shrimp without flambéing them?

Yes. Add the Cognac after removing the skillet from the heat, return it to the burner, and simmer vigorously for 2 to 3 minutes until the liquid has reduced and the harsh alcohol aroma has softened.

Can I use peeled shrimp instead of whole prawns?

Yes, although peeled shrimp cook faster and will give the pan juices less shellfish flavor. Begin checking them after about 1 minute of total cooking.

Why did my garlic become bitter?

The heat was probably too high or the garlic cooked too long. Keep the burner low and add the prawns as soon as the garlic begins to turn pale golden.

How can I tell when the prawns are cooked?

The shells should be pink, the flesh should be opaque, and the prawns should form a loose curve. The thickest part should reach 145°F (63°C).
