Camarones a la Diabla (Mexican Spicy Prawns)

Known for its punchy chilli heat and glossy red sauce, camarones a la diabla is a Mexican prawn dish made for serving hot from the pan. The prawns are cooked briefly in a blended tomato, garlic and chilli sauce, so they stay tender while the sauce becomes savoury, sharp and fiery. Guajillo brings depth and a gentle smokiness, while dried red chilli adds the more direct heat associated with the dish. Lime at the end keeps the sauce lively rather than heavy, and plain white rice is the ideal base for catching every spoonful.

Why this recipe works

  • Bold chilli depth: Guajillo chilli, dried red chilli, tomato, garlic and onion create a punchy sauce with both heat and savoury depth.
  • Fast cooking: The sauce is blended and simmered briefly, while the prawns cook in just a few minutes.
  • Bright finish: Lime juice cuts through the chilli-rich sauce and keeps the finished dish lively rather than heavy.

Get the most out of this recipe

Adjust the heat

  • For less heat: Use fewer dried red chillies and choose a mild chilli powder in place of guajillo if needed.
  • For a hotter sauce: Add extra dried red chilli to the blender, then taste again after the sauce has simmered.
  • To keep the heat balanced: Finish with lime and serve with rice; both help soften the intensity without muting the sauce.

Ingredient notes

  • Chilli choice matters: Guajillo gives a deeper, slightly smoky chilli flavour, while dried red chilli supplies sharper heat.
  • Use ripe tomato: A ripe tomato helps the sauce taste fuller and less acidic once blended and simmered.
  • Add lime at the end: Stirring in lime after cooking preserves its fresh, sharp flavour.

Common mistakes

  • Overcooking the prawns: Add the prawns only once the sauce has reduced slightly, then remove them from the heat as soon as they turn opaque and curl.
  • Letting the sauce spit or scorch: Keep the pan over a moderate heat while the blended sauce simmers so it darkens without catching.
  • Skipping the sauce simmer: Cook the blended sauce until it no longer tastes raw; this gives the chillies, tomato and aromatics a more rounded flavour.

Serving ideas

  • Serve with rice: Plain white rice is ideal for soaking up the hot chilli-tomato sauce.
  • Finish simply: Extra lime wedges or a little fresh coriander work well if you want a brighter finish.
  • Add something cooling: A crisp salad, sliced avocado or warm tortillas can round out the heat of the prawns.

  1. Rinse the rice until the water runs mostly clear. Tip into a saucepan with the water and 0.5 tsp of the fine sea salt, bring to the boil, then cover and cook on the lowest heat for 12 minutes. Take off the heat and leave, covered, for 5 minutes.
  2. Meanwhile, put the guajillo chili powder, dried red chili, tomatoes, garlic, onion and 150 ml water into a blender. Blend until very smooth, then taste and add a pinch more salt if needed.
  3. Heat the vegetable oil in a large frying pan over a medium heat. Pour in the blended sauce and simmer for 4 to 5 minutes, stirring often, until it darkens slightly and no longer tastes raw. Keep the heat moderate so it does not spit too aggressively.
  4. Add the prawns and cook for 2 to 3 minutes, stirring, until they are just opaque and curled. Season with the remaining fine sea salt and the black pepper. Squeeze in the lime juice and take off the heat as soon as the prawns are cooked through.
  5. Fluff the rice with a fork and divide between plates. Spoon the prawns and plenty of sauce over the top. Serve straight away while the sauce is glossy and hot.

Tips

  • For a smoother, less gritty sauce, blend for a full minute, then let it sit for 2 minutes so any bubbles settle before cooking.
  • If you are sensitive to heat, start with 1 dried red chili and add the second only after tasting the sauce once it has simmered.
  • Prawns cook very quickly, so add them only once the sauce has reduced slightly; overcooking will make them firm.

Substitutions

  • Replace long-grain white rice with jasmine rice for a more fragrant base.
  • Replace vegetable oil with olive oil for a fruitier finish.
  • Replace guajillo chili powder with mild chili powder for a gentler, less smoky heat.

Storage

  • Refrigerate up to 2 days
  • Cool leftovers quickly and refrigerate in a sealed container. Reheat the sauce gently in a frying pan over a low heat until piping hot, then add the prawns just to warm through; avoid boiling to prevent them turning tough. Rice reheats best with a splash of water, covered, in the microwave until piping hot.
