Grilled trout is a popular preparation in Peru’s Andean regions, especially near highland lakes, rivers, and fish farms. You cook it simply to preserve the trout’s mild flavor: season it with garlic, lime, salt, black pepper, and herbs, then cook it on a hot griddle or skillet until golden.
It is especially common in Cusco, Puno, Junín, and other highland regions of Peru. You usually serve it with potatoes, corn, rice, or fresh salad, making it a favorite for family lunches and Andean-style restaurants.

Peruvian Grilled Trout
- Prep Time: 25 minutes
- Cook Time: 12 minutes
- Total Time: 37 minutes
- Yield: 4
- Category: Main Course
- Cuisine: Peruvian
Ingredients
- 4 whole cleaned trout, scaled and gutted (about 1.2 kg total)
- 30 ml lime juice (2 tablespoons)
- 20 g garlic, minced or blended (4 cloves)
- 30 ml vegetable oil (2 tablespoons)
- 8 g salt (1½ teaspoons)
- 3 g ground black pepper (¾ teaspoon)
- 3 g ground cumin (½ teaspoon)
- 5 g dried oregano (1 teaspoon)
- 20 g fresh cilantro, chopped (4 tablespoons)
- 500 g boiled yellow potatoes or native potatoes
- 4 medium ears of corn, boiled and cut in half
- 200 g Peruvian onion salad
- 30 ml additional oil for the griddle (2 tablespoons)
Preparation
- Clean and dry the trout, rinse the fish under cold water, make sure the cavities are completely clean, and pat them very dry with paper towels. Make two shallow diagonal cuts on each side so the seasoning penetrates better and the fish cooks evenly.
- Make the seasoning, combine the lime juice, garlic, oil, salt, black pepper, cumin, oregano, and cilantro. Rub the mixture inside and outside each trout, making sure it reaches the cuts. Refrigerate for 20 minutes.
- Heat the griddle, place a griddle or wide skillet over medium-high heat and add the additional oil. Once hot, place the trout on the surface without overcrowding and cook for 5 to 6 minutes on the first side, until the skin is golden and releases easily.
- Cook the other side, turn the trout carefully with a wide spatula and cook for another 4 to 5 minutes. The flesh should look opaque, flake easily with a fork, and be fully cooked without becoming dry.
- Serve immediately, place each trout on a plate and serve it with boiled potatoes, corn, and Peruvian onion salad. Enjoy it right away to keep the skin golden and the flesh juicy.
Chef’s Tips
- Pat the trout dry before cooking so the skin browns properly and does not stick to the griddle.
- Do not move the fish during the first minutes of cooking; wait until the skin browns before turning it.
- Use medium-high heat, not extreme heat, so the outside does not burn before the fish is cooked through.
- Marinate the trout only briefly. Lime juice can affect the texture if it sits too long.
- Use a wide spatula when turning the fish to keep it from breaking apart.
Traditional Variations
In some Andean regions, trout is seasoned with huacatay, ají amarillo, or a light garlic-and-lime sauce. It is also commonly served fried, breaded, or with Peruvian chile sauce.
The grilled version stands out for its simple preparation and its popularity in highland areas, where fresh trout is traditionally served with native potatoes, boiled corn, and local ingredients.
How to Serve It
Serve grilled trout immediately, with golden skin and a generous portion of boiled potatoes. Add corn and Peruvian onion salad for a traditional Andean-style plate.
Pair it with chicha morada, homemade limeade, or muña tea. Ají amarillo sauce or rocoto sauce also works especially well with trout.

Cooking trout on a griddle preserves its natural flavor and delicate texture. For that reason, it is one of the most popular preparations when fresh trout is available.
