Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 lb diced potatoes with 1 tbsp olive oil, 1/4 tsp salt, and 1/8 tsp black pepper on a baking sheet. Roast for 25-30 minutes until golden and crispy, flipping halfway through.
  2. Step 2: Pat 4 (6 oz) cod fillets dry and season with 1/4 tsp salt and 1/8 tsp black pepper. Heat 1 tbsp olive oil in a large oven-safe skillet over medium-high heat. Add cod and sear for 3-4 minutes per side until golden brown, then transfer skillet to oven and bake for 5-7 minutes until cooked through.
  3. Step 3: Whisk 1 tbsp lemon juice, 2 tbsp fresh dill, 2 tbsp unsalted butter, and 1/4 tsp salt in a small bowl. Remove skillet from oven, transfer cod to a plate, and pour sauce over the top. Serve with roasted potatoes and garnish with 2 tbsp chopped chives.

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

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Pan-Seared Cod with Lemon-Dill Sauce and Roasted 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.
