Pan-Seared Trout with Lemon-Caper Brown Butter (30-Minute)
Crisp-edged trout fillets glisten with a nutty brown-butter sauce punctuated by bright lemon and briny capers, paired with tender herb-scented new potatoes. The contrast of crunchy skin and flaky flesh with silky, slightly toasted butter creates a satisfying mix of textures and flavors that feels both fresh and indulgent.
Use fingerling or small new potatoes for quick cooking; you can swap capers for green olives if you prefer a milder brine. If trout is unavailable, use salmon or Arctic char, adjusting pan time for thicker fillets. For a lighter finish, replace half the butter with olive oil when making the sauce.
Serve this skillet for weeknight dinners, casual date nights, or a simple weekend fish supper. Pair with a crisp green salad, steamed green beans, or crusty bread to soak up the sauce. Leftovers keep well refrigerated for 1–2 days and reheat gently in a skillet to preserve the trout’s texture.
How to Make It
-
1
Bring a medium pot of salted water to a simmer. Add the new potatoes and cook until just tender when pierced with a fork, about 10–12 minutes. Drain and set aside to steam-dry for 2 minutes.
-
2
While potatoes cook, pat trout fillets very dry with paper towels and season both sides with salt and black pepper. Zest the lemon and cut it in half; chop parsley and mince garlic.
-
3
Heat 1 tbsp olive oil in a large nonstick or stainless-steel skillet over medium-high heat. Add the potatoes cut-side down (halved if large) and sprinkle with smoked paprika if using. Cook without stirring until golden and crisp, about 4–5 minutes, then flip and crisp the other side for 3 minutes. Transfer potatoes to a plate and keep warm.
-

Add the remaining 1 tbsp olive oil to the skillet and reduce heat to medium. Place trout fillets skin-side down in a single layer; press lightly with a spatula for 10–15 seconds to keep skin flat. Cook skin-side down until the skin is crisp and the flesh is opaque two-thirds of the way up, about 3–4 minutes depending on thickness.
-
5
Flip the fillets and cook the top side just until cooked through, about 1 minute more for 150 g fillets. Transfer trout to the plate with potatoes and tent loosely with foil to rest.
-
6
Wipe the skillet clean, return to medium heat, and add the butter. Swirl the butter as it melts and foams, cooking until it turns a light golden-brown and develops a toasted nut scent, about 2–3 minutes. Add the minced garlic and capers and cook 20–30 seconds to soften and warm.
-
7
Remove the skillet from heat and stir in lemon zest and lemon juice. Taste and adjust seasoning with a pinch of salt and pepper as needed.

Return trout and potatoes to the skillet or arrange on a serving platter. Spoon the lemon-caper brown butter over the fillets, sprinkle with chopped parsley, and serve immediately with lemon wedges on the side.
