30-Minute Oven-Baked Trout
Delicate whole trout fillets baked until flaky and topped with nutty brown butter, toasted almonds, and fresh parsley. A classic New Orleans-inspired preparation that's elegant yet simple. The brown butter adds rich, caramelized depth while almonds provide textural contrast. Perfect for weeknight dinners or entertaining guests who appreciate refined seafood. This version keeps the fish moist by baking rather than pan-frying and finishes with warm sauce for maximum flavor.
Ingredients
Instructions
- 1
Preheat oven to 375F.
- 2
Season trout fillets with salt and pepper, rub lightly with olive oil on both sides.
- 3
Place on parchment-lined baking tray skin side down.
- 4
Bake 10-12 minutes until flesh flakes easily when pricked with a fork.
- 5
Meanwhile, toast slivered almonds in a pan over medium heat 3-5 minutes, stirring constantly, until light brown. Transfer to a bowl and reserve some for garnish.
- 6
In the same pan on medium heat, melt butter and cook, stirring gently, until brown and nutty-smelling, about 6-7 minutes.
- 7
Transfer brown butter immediately to the bowl with almonds to prevent burning.
- 8
Stir chopped parsley into the sauce.
- 9
Pour brown butter sauce over baked trout fillets.
- 10
Garnish with reserved toasted almonds and serve.
Tips
Toast almonds in a dry pan before browning butter to develop their flavor separately and prevent them from burning during the butter's longer cooking time.
Watch the brown butter carefully once it begins to color; it can burn quickly. Transfer immediately when fragrant and nutty to stop the cooking process.
Good to Know
Store leftover baked trout covered in the refrigerator up to 2 days. Brown butter sauce best served fresh but keeps 1 day refrigerated; warm gently before serving.
Toast almonds and prepare brown butter sauce up to 4 hours ahead. Store separately at room temperature. Bake trout just before serving.
Serve immediately on warm plates while trout is hot and butter sauce is still warm and glossy.
Common Mistakes
Don't skip constant stirring when toasting almonds or browning butter; both burn quickly and ruin the dish.
Don't let brown butter cool before pouring over fish; it will solidify and coat unevenly.
Don't overcook the trout; check doneness at 10 minutes to avoid dry flesh.

FAQ
Can I make this with trout fillets instead of whole fish?
Yes, fillets work well and reduce cooking time slightly to 8-10 minutes. They're easier to portion but lose some visual appeal. Whole fish presents more elegantly.
What if I don't have a parchment-lined baking tray?
Butter a standard baking sheet or use foil instead of parchment. The key is preventing sticking. Check at 10 minutes since heat distribution may vary.
Can I freeze leftover trout?
Freeze baked trout up to 1 month in an airtight container, but brown butter sauce does not freeze well due to its emulsified texture. Prepare sauce fresh after thawing.
