Peru’s most iconic dish: raw white fish “cooked” in fresh lime juice until firm and opaque, tossed with red onion and cilantro, and served over crisp lettuce instead of the traditional starchy sides.
What You’ll Need
Servings: 4 servings
Calories: 220kcal
Ingredients
- 1 1/2 lb fresh white fish fillet (corvina or sea bass) cut into 1/2-inch cubes (sub: cod, halibut, or snapper)
- 1/2 cup freshly squeezed lime juice about 6–8 limes
- 1/2 red onion very thinly sliced
- 1 aji limo or aji amarillo pepper minced, seeds removed for less heat (sub: serrano or jalapeño)
- 1/4 cup fresh cilantro chopped
- 1 clove garlic minced
- 1 tsp sea salt
- 1/4 tsp freshly ground black pepper
- 1/2 avocado sliced, for serving
- Butter lettuce leaves, for serving (sub: traditional camote and choclo, omitted here to keep this keto)
Instructions
- Pat the fish cubes completely dry with paper towels and place in a non-reactive glass or ceramic bowl.
- Season the fish with sea salt and black pepper, then add the minced garlic and chili pepper.
- Pour the fresh lime juice over the fish, making sure every piece is submerged.
- Let marinate 8–12 minutes, until the fish turns opaque and firm — don't over-marinate, or the texture turns chalky.
- Fold in the sliced red onion and chopped cilantro just before serving.
- Spoon the ceviche and its citrus marinade over butter lettuce leaves.
- Garnish with avocado slices and serve immediately.

Health Benefits
