This trout ceviche is not raw. The fish is marinated in lime, then seared on a griddle and layered over avocado mashed with cream and mayonnaise, with red onion, sweet corn and cilantro on top. It is served cold, in a glass or on a plate, and eaten with patacones.
Cooking the fish is a deliberate choice rather than a shortcut, and it is worth explaining why, because it is the same question a lot of people arrive here asking.
Can you make ceviche with trout?
You can, and people do. But trout is a freshwater fish, and that is the part worth knowing about. The species traditionally used for ceviche (sea bass, corvina, snapper, shrimp) are saltwater, and saltwater fish carry a lower parasite risk than freshwater ones.
The common assumption is that the lime takes care of it. It does not. Citrus juice denatures the proteins in fish, which is why raw fish in lime turns white, firm and opaque and looks for all the world as though it has been cooked. But denaturing is not heating, and it does not kill parasites.
If you genuinely want raw trout, the answer is freezing, not lime. The FDA Food Code sets out the parameters for fish that will be served raw: frozen at -4°F (-20°C) or below for seven days, or at -31°F (-35°C) until solid and then held at that temperature for fifteen hours. A domestic freezer usually runs at about 0°F, which does not meet either. This is why sushi restaurants buy fish that has been commercially frozen.
Searing the trout, as this recipe does, makes the whole question go away. You lose the raw texture and you keep the lime, the onion, the cilantro and the cold assembly, which is most of what makes a ceviche taste like one.
Boning the trout
Head, fins, tail and skin come off first. Then the pin bones, and this is the fiddly part: run your fingers slowly along the fillet and you will feel them before you see them, a row running down the thickest part.
Pull each one with tweezers, in the direction it points rather than straight up, or the flesh tears around it. Fishmongers will do this for you if you ask, and it is a reasonable thing to ask.
The avocado cream
Two ripe avocados mashed with a fork (not blended, since a food processor makes it gluey), then loosened with mayonnaise and cream and seasoned with salt. It goes on the bottom of the glass and everything else sits on it.
On keeping it green: what actually stops avocado browning is acid and the absence of air. A squeeze of lime slows the reaction, and pressing plastic wrap flat onto the surface (touching it, not stretched over the bowl) keeps the oxygen off. The mayonnaise helps a little, because it contains acid and because fat forms a barrier. Cream does not, whatever you may have read.
The practical answer is to make it close to serving. It is a five-minute job.
Building the dish
The order matters, because it is a layered dish and it is meant to be seen from the side if you serve it in a glass: avocado cream at the bottom, then the red onion cut into fine slivers, then the seared trout broken into pieces, then the corn, and the cilantro scattered last.
The corn (maicitos, sweet corn kernels, drained) is there for sweetness and a bit of resistance against the soft avocado and the flaking fish. Toasted corn, cancha, is a good swap if you want more crunch.
Serve it cold, with patacones on the side: green plantain sliced, fried, flattened and fried again. They are what you eat it with, and they do the job a tortilla chip does elsewhere.
Starter or main
Either, depending on how much you put in the glass. A kilo of trout across four people is a main course; the same recipe divided into six small glasses is a starter, and it looks better in the smaller size.

Trout Ceviche FAQ
You can, but trout is freshwater fish, and freshwater fish carry a parasite risk that saltwater species used for ceviche mostly do not. That is why this recipe marinates the trout in lime and then sears it. If you want it raw, the fish has to be frozen first to kill parasites.
Not in the way that matters for safety. The acid denatures the proteins, so the flesh turns opaque and firm and looks cooked. It does not reach a temperature that kills parasites, and it does not reliably kill bacteria either. Ceviche is raw fish that looks cooked.
Only if you plan to serve it raw. The FDA Food Code calls for freezing at -4°F (-20°C) or below for seven days, or at -31°F (-35°C) until solid and then held fifteen hours. Most home freezers sit around 0°F, which is not cold enough. Searing the fish, as this recipe does, avoids the issue.
It is a ceviche in the looser Latin American sense: lime, red onion, cilantro and a cold assembly. Purists would call it a seared fish salad, and they would have a point. What it is not is a Peruvian-style raw cure, and the recipe is better for being honest about that.
Acid and air are what matter. Lime juice slows the browning, and pressing plastic wrap directly onto the surface keeps oxygen off it. Mayonnaise helps a little, since it contains acid and its fat forms a barrier. Cream does not prevent browning, despite being widely repeated.
Corn kernels, canned or cooked sweet corn, drained. In Colombia they are scattered over ceviches and salads for sweetness and a bit of bite. Around 200 g, roughly a cup, is right for four servings. Toasted corn, cancha, works too and gives more crunch.

Instructions
- Wash the trout. Remove the head, fins, tail and skin.
- Take out the bones. Run your fingers slowly along the fillet: you will feel the pin bones before you see them. Pull each one out with tweezers, in the direction it points, so the flesh does not tear.
- Squeeze the lime juice over the trout and leave it to stand for 20 to 30 minutes.
- Halve the avocados, remove the stone and the skin, and mash the flesh with a fork to a purée.
- Add the mayonnaise, the cream and a little salt to the avocado and stir until smooth.
- Cut the onion into thin slivers and set aside.
- Put the trout on a hot griddle or heavy pan, salt it, and cook over medium heat on both sides until it is opaque all the way through and flakes when pressed.
- To assemble, spread the avocado cream over the base of the plate or glass, then the onion slivers, then the trout, then the corn, and the cilantro last.
- Serve with patacones, crisp fried slices of green plantain, on the side.
