Tiradito de Atún (Peruvian-Style Tuna with Aji Amarillo and Lime)

Peruvian tiradito sits somewhere between ceviche and sashimi: raw fish cut into fine slices and finished with a vivid citrus dressing rather than marinated for long. In this tuna version, lime and aji amarillo give the sauce its sharp, fruity heat, while garlic, coriander and olive oil round it out into something smooth and punchy. The dish is served cold and assembled at the last moment, so the tuna stays silky and clean-tasting, with red onion adding crisp freshness. It is light enough as a starter, but distinctive enough for a simple dinner when very fresh, sashimi-grade fish is the focus.

Why this recipe works

  • Fast and precise: The tuna needs only brief chilling, slicing and dressing, making the dish quick without sacrificing presentation.
  • Sharp but balanced dressing: Lime gives the sauce its brightness, while olive oil softens the acidity and helps the aji amarillo coat the fish evenly.
  • Clean texture contrast: Silky raw tuna is set against crisp red onion and fresh herbs for a light, fresh finish.

Timing notes

  • Briefly chill before slicing: A short spell in the freezer firms the tuna enough for cleaner, thinner slices without freezing it through.
  • Dress just before serving: Lime begins to firm and turn the tuna opaque as soon as it touches the fish, so add the dressing at the last moment.

Ingredient notes

  • Use suitable tuna: Choose sashimi-grade tuna from a trusted supplier and keep it well chilled until slicing.
  • Slice against the grain: Cutting against the grain gives the tuna a more delicate bite and a cleaner presentation.
  • Adjust the citrus: Taste the dressing before serving and add a little more lime if you want a sharper, more ceviche-like finish.

Adjust the heat

  • For less heat: Use less aji amarillo paste and let the lime and herbs lead the dressing.
  • For more heat: Blend in extra aji amarillo gradually, tasting as you go so the chilli does not overpower the tuna.
  • Keep the chilli rounded: If the dressing tastes too sharp or hot, a little more olive oil can soften the edges without dulling the flavour.

Common mistakes

  • Dressing too early: Adding the sauce too far in advance changes the tuna’s colour and texture, making it less silky.
  • Slicing too thickly: Thick pieces can feel heavy and unevenly seasoned; aim for thin, even slices that take the dressing lightly.
  • Holding dressed fish: If not serving straight away, store the tuna and dressing separately in the fridge and assemble only when ready to eat.

  1. Put the tuna in the freezer for 10 minutes to firm it up for slicing. Meanwhile, juice the limes. Peel the garlic and set aside.
  2. Make the dressing: in a blender, combine the lime juice, aji amarillo paste, garlic, most of the fresh coriander (reserve a little to finish), and the extra virgin olive oil. Blend until smooth and bright, then taste and adjust with a little more lime juice if you want it sharper.
  3. Thinly slice the tuna against the grain and arrange in a single layer on a chilled serving plate. Thinly slice the red onion. Spoon the dressing over the tuna just before serving, then scatter over the red onion and the reserved coriander.

Recipe notes

Tips

  • For the cleanest slices, use a long sharp knife and wipe the blade between cuts.
  • Dress the tuna at the last moment so the surface stays silky rather than turning opaque.
  • Food safety: if serving raw fish to pregnant people, young children, older adults, or anyone immunocompromised, use sashimi-grade tuna from a trusted supplier and keep it well chilled.

Substitutions

  • Replace extra virgin olive oil with avocado oil for a more neutral finish.
  • Replace fresh coriander with fresh flat-leaf parsley for a different herbal note.
  • Replace lime with lemon for a slightly softer, less aromatic citrus flavour.

Storage

  • Refrigerate up to 1 days
  • Best eaten immediately. If needed, store the sliced tuna and dressing separately in the fridge and assemble just before serving; once dressed, the tuna will turn opaque and soften.
