Pan-Roasted Whole Trout with Lemon-Herb Butter and Smashed Potatoes (30-Minute)
Crisp skin gives way to moist, flaky flesh while bright lemon and herb butter adds glossy richness—this skillet-forward meal comes together fast for an impressive weeknight dinner. Tender smashed new potatoes brown at the edges for a pleasing contrast of textures alongside the delicate fish.
Swap herbs or finish options easily: use dill or chives instead of parsley, replace butter with olive oil for a dairy-free version, or pan-sear fillets instead of whole trout if preferred. If trout isn’t available, small whole fish like sea bream or whole rainbow trout work well.
Serve for casual weeknights or small dinner gatherings; pair with a simple green salad, steamed asparagus, or a chilled glass of light white wine. Leftovers keep 1–2 days refrigerated—reheat gently in a low oven to preserve texture.
How to Make It
-
1
Boil potatoes: Place new potatoes in a large pot, cover with cold salted water, bring to a boil, and simmer until just tender when pierced, about 12–15 minutes. Drain and return to the pot.
-
2
Smash potatoes: Lightly smash each potato with the bottom of a cup or a fork so they flatten slightly but hold together. Toss with 1 tbsp olive oil and 1/2 tsp salt.
-
3
Brown potatoes: Heat a large nonstick or cast-iron skillet over medium-high heat and add 1 tbsp olive oil. Arrange smashed potatoes in a single layer and cook without moving until golden and crisp on one side, about 4–5 minutes. Flip and crisp the other side 2–3 minutes. Transfer potatoes to a warm plate and keep skillet handy.
-
4
Prepare trout: Pat trout dry inside and out with paper towels, season cavity and skin lightly with 1 tsp salt and 1/2 tsp black pepper, and tuck 1 thyme sprig and a few lemon slices (from 1 lemon) into each cavity if desired.
-
5
Pan-roast trout: Reheat the skillet used for potatoes over medium-high and add remaining 1 tbsp olive oil. When shimmering, place trout skin-side down and press gently to ensure full contact with the pan. Cook undisturbed until skin is deeply golden and crisp, 4–5 minutes.
-
6
Finish trout: Flip trout carefully and reduce heat to medium. Add butter, minced garlic, remaining thyme sprigs, and capers to the pan. Spoon melted butter over the fish and cook 2–3 minutes more until fish just flakes and registers about 56–60°C (133–140°F) at the thickest point. Transfer trout to a platter.
-
7
Make lemon-herb butter: Remove skillet from heat, swirl in lemon juice (from 1 lemon) and lemon zest, then stir in chopped parsley. Taste and adjust seasoning with remaining salt and pepper.
-
8
Plate and serve: Spoon lemon-herb butter and pan juices over the trout, arrange smashed potatoes alongside, and garnish with extra parsley or lemon wedges. Serve immediately.
