Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb halved fingerling potatoes with 2 tbsp olive oil, 1/2 tsp salt, and 1/4 tsp black pepper on a baking sheet. Roast for 25-30 minutes, stirring halfway, until golden and crisp.
  2. Step 2: Season 4 trout fillets evenly with 1 tsp salt and 1/2 tsp black pepper. Heat 1 tbsp olive oil in a large nonstick skillet over medium-high heat. Add trout skin-side down and cook for 4-5 minutes until skin is crisp and edges turn opaque.
  3. Step 3: Flip the trout carefully and cook an additional 2-3 minutes until just cooked through and flakes easily.
  4. Step 4: In a small saucepan, melt 4 tbsp unsalted butter over low heat. Add 2 minced garlic cloves and cook for 1 minute until fragrant. Remove from heat, then stir in 2 tbsp fresh lemon juice and 2 tbsp chopped fresh dill.
  5. Step 5: Serve the trout fillets topped generously with the lemon-dill butter sauce alongside the roasted fingerling potatoes.

How do I store leftover Pan-Seared Trout with Lemon-Dill Butter Sauce and Roasted Fingerling Potatoes?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Pan-Seared Trout with Lemon-Dill Butter Sauce and Roasted Fingerling Potatoes?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut).

How do I scale Pan-Seared Trout with Lemon-Dill Butter Sauce and Roasted Fingerling Potatoes for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
