About this recipe

Jumbo prawn fajitas marinated in garlic, lime and Tex-Mex spices, sautéed with mixed peppers and onion. A lighter and more elegant version of the classic fajita, perfect for seafood lovers.

History & Origin

Prawn fajitas are the most refined and lighter version of the Tex-Mex concept - an adaptation that reflects the coastal influence of south Texas, where the Gulf of Mexico puts fresh seafood within everyone's reach. Prawn fajitas emerged in the 1980s as part of the expansion of the Tex-Mex menu towards lighter and healthier options, adapting to the tastes of a new generation of consumers who wanted the intense flavours of border cuisine without the heaviness of red meat. The fishing communities of Corpus Christi, Galveston and the Rio Grande Valley in Texas had been consuming fresh prawns for centuries, prepared Tex-Mex style with abundant spices, lime and the technique of the smoking-hot pan. The jumbo prawn, cooked for barely 3 minutes to hit the exact right point, acquires an extraordinary layer of flavour from the garlic and chipotle marinade reminiscent of Gulf Coast flavours. Today, prawn fajitas are an obligatory presence at any serious Tex-Mex restaurant, appreciated both for their relative elegance and for their speed of preparation, since prawns cook in half the time of any meat. In the United Kingdom, this recipe has found enthusiastic followers thanks to the abundance of quality large prawns available at fishmongers.

Method

  1. 1

    Peel and clean the prawns, leaving the tail on. Marinate with lime juice, minced garlic, cumin, chilli powder, smoked paprika, salt and a drizzle of oil. Leave to rest for 10 minutes.

    Step 1

    💡 Do not marinate for more than 15 minutes or the acid from the lime will start to 'cook' the prawns.

  2. 2

    Heat a cast iron pan over a very high heat. Sauté the sliced peppers and onion with a little oil for 4–5 minutes until they have a little colour. Remove and set aside.

    Step 2
  3. 3

    In the same pan over a very high heat, add the marinated prawns in a single layer. Cook for 1–2 minutes per side until pink and curled. Do not overcook.

    Step 3

    💡 Prawns are ready when they form a C shape. If they form an O shape, they are overcooked.

  4. 4

    Mix the prawns with the reserved peppers and onion. Squeeze a little lime over the top. Serve immediately in the sizzling pan with warm tortillas and accompaniments.
