Enjoy a fresh, delicate seafood dinner with Roasted Lemon Garlic Trout and Green Beans. Tender, flaky trout fillets roast alongside crisp green beans on a single baking sheet, coated in a bright butter-garlic glaze with fresh lemon and herbs.
The secret to juicy trout and tender-crisp green beans is Baking at High Heat (425°F / 220°C) for a Fast 10 to 12 Minutes. Delicate trout fillets cook rapidly, so pairing them with fresh, trimmed green beans tossed in olive oil ensures the fish remains moist and flaky while the beans acquire a slight blistered crunch.

Step-by-Step Instructions
1.Prep Oven & Sheet Pan:3 min.
Preheat your oven to 425°F (220°C) and line a large, rimmed baking sheet with parchment paper or foil.
2.Whisk Lemon Garlic Glaze:3 min.
In a small bowl, whisk together 3 tablespoons melted butter, 4 minced garlic cloves, 1 tablespoon fresh lemon juice, 1 teaspoon lemon zest, dried oregano, ½ teaspoon salt, and ¼ teaspoon black pepper.
3.Arrange & Season Pan:3 min.
Pat 4 trout fillets dry with paper towels. Place 1 lb trimmed green beans on one side of the baking sheet, toss with 1 tablespoon olive oil, salt, and pepper, and spread in a single layer. Arrange the trout fillets skin-side down on the empty side of the pan and spoon the lemon garlic glaze evenly over the top of each fillet.
4.High-Heat Fast Roast:12 min.
Bake at 425°F (220°C) for 10 to 12 minutes, until the trout flakes easily with a fork (145°F / 63°C internal temperature) and the green beans are tender-crisp with blistered edges.
5.Garnish & Serve Warm:1 min.
Remove from the oven, arrange fresh lemon slices over the top, sprinkle with fresh parsley or dill, and serve immediately!
Expert Tips for Success
- Pat the Trout Dry: Surface moisture prevents skin from rendering and can cause fish to steam. Press fillets with paper towels before glazing.
- Keep Green Beans Dry: Ensure green beans are completely dry after washing so they roast and blister in the olive oil instead of steaming.
- Bake Skin-Side Down: Roasting skin-side down insulates the delicate fish flesh against the hot pan, keeping the trout exceptionally juicy.
