Ingredients

Instructions

  1. Step 1: Pat 450g salmon fillets dry with paper towels and season the skin side with salt and pepper. Heat 2 tbsp olive oil in a cast iron skillet over medium-high heat until shimmering but not smoking.
  2. Step 2: Place salmon skin-side down in the hot skillet and press gently with a spatula for 10 seconds to ensure even contact, then cook undisturbed for 8-10 minutes until the skin is golden brown and crisp.
  3. Step 3: Flip the salmon and cook for 3-4 minutes more until the internal temperature reaches 120°F (49°C) for medium-rare, then transfer to a plate.
  4. Step 4: Reduce heat to medium and add 1 tbsp lemon juice, 1 tbsp fresh dill, and 1 minced garlic clove to the skillet, stirring to deglaze the pan for 1 minute.
  5. Step 5: Remove from heat and whisk in 2 tbsp cold unsalted butter until the sauce emulsifies and becomes glossy. Pour the sauce over the salmon immediately and serve with additional dill garnish.

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 Cast Iron Seared Salmon with Lemon-Dill Sauce?

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 Cast Iron Seared Salmon with Lemon-Dill Sauce for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). 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.
