Chili-Lemon Roasted Whole Trout with Garlicky Greens

Directions

1. Heat the oven and dry the trout

   Heat the oven to 425°F with a rack in the center. Line a rimmed half-sheet pan with parchment. Pat the trout dry inside and out, including around the fins; dry skin roasts instead of steaming. Cut three shallow diagonal slashes through the skin on each side of each fish.

2. Build the chili-lemon seasoning

   In a small bowl, combine 2 tablespoons olive oil, the grated garlic, fennel seeds, red pepper flakes, 1 1/2 teaspoons salt, and 1/2 teaspoon pepper. Finely grate 1 teaspoon zest from one lemon into the bowl, then cut that lemon into thin half-moons. Cut the second lemon into serving wedges.

3. Season and fill the fish

   Rub the seasoned oil over both sides of the trout and into the slashes. Season the cavities with 1/4 teaspoon salt, then fill each with half the lemon half-moons and a few parsley stems. Arrange the fish at least 2 inches apart on the prepared pan.

4. Roast to safe doneness

   Roast for 18 to 23 minutes, depending on thickness, until the flesh is opaque and flakes cleanly at the thickest point. An instant-read thermometer inserted into the thickest flesh without touching bone should register 145°F. Rest the trout on the pan for 3 minutes.

5. Wilt the garlicky greens

   While the fish roasts, heat the remaining 1 tablespoon olive oil and the butter in a large skillet over medium heat. Add the sliced garlic and cook for 30 seconds. Add the greens, water, remaining 1/2 teaspoon salt, and remaining 1/4 teaspoon pepper. Toss for 2 to 4 minutes until just wilted and glossy.

6. Finish and portion

   Transfer the trout to a platter with the greens. Scatter with parsley leaves and serve with the lemon wedges. To portion, lift the top fillet away from the backbone, remove the backbone in one piece, and divide the lower fillet; check each serving for pin bones.

Why this works

Swaps & notes

Easy swaps

• Use two cleaned branzino of similar weight; begin checking at 17 minutes and rely on the thermometer.
• Replace spinach with chopped Swiss chard; sauté the sliced stems for 3 minutes before adding the leaves.
• For a dairy-free dinner, replace the butter with another tablespoon of olive oil.

Cook notes

• Ask the fish counter to clean and scale the trout, but inspect the cavities and rinse away any remaining bloodline only if needed; pat completely dry afterward.
• USDA guidance for fish is 145°F at the thickest part. The flesh should also be opaque and separate easily with a fork.
• Whole fish contains small pin bones. Portion carefully and remind diners to check each bite, especially when serving children.

Storage

Remove the flesh from the bones before refrigerating. Store fish and greens in separate airtight containers for up to 3 days. Reheat covered in a 300°F oven with a teaspoon of water until the center reaches 165°F; the greens can be rewarmed briefly in a skillet. Do not freeze the cooked greens, which become watery.
