Trout with Almonds and Brown Butter (Truite aux Amandes et Beurre Noisette)

Truite aux amandes brings a classic French treatment to delicate trout: quick pan-frying, crisp skin and a warm beurre noisette spooned over at the end. The brown butter gives the fish its distinctive hazelnut aroma, while toasted sliced almonds add crunch without weighing it down. A little lemon zest, juice and parsley keep the richness in check, making the dish feel elegant but still practical for a fast dinner. Serve straight away, while the butter is fragrant and the trout is tender and just opaque.

Why this recipe works

  • Nutty depth: Beurre noisette gives the trout a warm, toasted flavour without needing a heavy sauce.
  • Delicate crunch: A light flour coating, crisp skin and toasted almonds add texture while keeping the fish tender.
  • Richness balanced: Lemon zest and juice lift the brown butter and stop the finished dish feeling too rich.

Timing notes

  • Serve immediately: The trout is best eaten as soon as the brown butter is spooned over, while the skin and almonds still have contrast.
  • Prepare before frying: Toast the almonds and have the lemon and parsley ready before cooking the fish, as the final sauce comes together quickly.

Common mistakes

  • Watch the brown butter: Once the butter smells nutty and the milk solids turn deep golden, remove it from the heat promptly to prevent bitterness.
  • Do not overcook the trout: Take the fish off the heat when the thickest part is just opaque and flakes gently; residual heat will finish it.

Ingredient notes

  • Use skin-on trout: Skin-on fillets help protect the delicate flesh during frying and give the dish a more satisfying texture.
  • Dry before flouring: Patting the trout dry keeps the flour coating light and helps it brown cleanly in the pan.
  • Choose unsalted butter: Unsalted butter gives better control over seasoning and lets the nutty flavour of the beurre noisette come through.

Serving ideas

  • Simple sides: Serve with boiled new potatoes, green beans, wilted greens or a crisp salad to balance the rich butter sauce.
  • Finish with freshness: Extra lemon juice and chopped parsley add brightness just before serving.

  1. Pat the trout dry, then season all over with the fine sea salt and black pepper. Put the plain flour on a plate and lightly dust the trout, shaking off any excess. Finely zest the lemon, then cut it in half.
  2. Heat a large frying pan over a medium heat and add the sliced almonds. Toast for 2 to 3 minutes, stirring often, until golden and fragrant, then tip onto a plate.
  3. Wipe out the pan, return it to a medium-high heat, and add the olive oil and 20 g of the unsalted butter. When the butter foams, add the trout skin-side down and cook for 3 to 4 minutes until the skin is crisp. Turn and cook for 1 to 2 minutes more, until just opaque and the flesh flakes easily.
  4. Transfer the trout to warm plates. Lower the heat to medium and add the remaining unsalted butter to the pan. Cook, swirling, for 2 to 4 minutes until the butter turns deep golden with a nutty aroma, then immediately take it off the heat.
  5. Stir the toasted almonds into the browned butter, then add the lemon zest and squeeze in a little lemon juice to taste. Finely chop the fresh parsley and stir it through. Spoon the beurre noisette over the trout and serve straight away with extra lemon juice if you like.

Recipe notes

Tips

  • Keep a close eye on the butter as it browns: once the milk solids turn hazelnut-coloured, it can burn quickly, so take it off the heat promptly.
  • For the juiciest fish, stop cooking when the thickest part is just opaque and flakes with gentle pressure; it will finish cooking slightly from residual heat.

Substitutions

  • Replace the sliced almonds with almonds for a chunkier crunch; roughly chop them before toasting.
  • Replace the fresh parsley with fresh dill for a more aromatic, aniseed note.

Storage

  • Refrigerate up to 1 days
  • Best eaten straight away. If you have leftovers, cool quickly and refrigerate; reheat gently in a frying pan over a low heat with a small knob of unsalted butter until piping hot, or enjoy cold as flakes over a salad.
