Why This Gambas al Ajillo Recipe Works

Authentic gambas al ajillo relies on quality ingredients and a simple technique. The key is to gently infuse the olive oil with garlic and chili, then cook the prawns quickly to keep them tender and juicy. Using shell-on prawns adds depth of flavor, but this recipe also works with peeled shrimp for convenience.

Ingredients for Spanish Garlic Shrimp

• 8 sustainably sourced raw shell-on king prawns
• 4 garlic cloves, thinly sliced
• 120ml olive oil (use a good quality extra virgin)
• A few flat-leaf parsley stems, chopped
• 4 small dried chillies, or 1 tsp cayenne pepper
• 2 tsp sherry vinegar or lemon juice
• Salt and black pepper
• Bread slices, to serve

Step-by-Step Instructions for Perfect Gambas al Ajillo

1. Prepare the Prawns

Peel the shell-on prawns by twisting off the heads, then peel down the back and twist off the tails. Keep all the shells – they add incredible flavor to the oil. Devein the prawns by running a small knife down the back and removing the dark digestive tract if visible.

2. Infuse the Olive Oil

Heat the olive oil in a large skillet over medium heat. Add the prawn shells and cook for 3-4 minutes, pressing them with a spoon to release their juices. Remove the shells and discard. This step creates a rich, seafood-infused oil that is the soul of this dish.

3. Sizzle Garlic and Chili

Add the sliced garlic and dried chillies (or cayenne) to the hot oil. Cook for 30-60 seconds until fragrant, but do not let the garlic burn – it should be golden, not brown. The garlic will crisp up slightly, adding texture and flavor.

4. Cook the Prawns

Season the prawns with salt and pepper, then add them to the skillet in a single layer. Cook for 1-2 minutes per side, until they turn pink and are just cooked through. Be careful not to overcook – they should be tender and juicy.

5. Finish and Serve

Remove the skillet from heat and stir in the sherry vinegar or lemon juice and chopped parsley. The residual heat will meld the flavors. Serve immediately in the sizzling skillet with crusty bread for dipping into the glorious garlicky oil.
