Instructions

  1. Step 1: Pat dry 2 salmon fillets (6 oz each) with skin on. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 1 tbsp olive oil in a non-stick skillet over medium-high heat until shimmering. Place the salmon fillets skin-side down and cook for 5-6 minutes without moving until the skin is crispy and golden.
  3. Step 3: Flip the salmon carefully and cook for an additional 2-3 minutes until the fish is opaque and flakes easily with a fork.
  4. Step 4: While salmon cooks, combine 3 tbsp softened unsalted butter, 1 tbsp Dijon mustard, 1 tbsp finely chopped fresh parsley, and 1 tbsp finely chopped fresh dill in a small bowl until smooth.
  5. Step 5: Remove salmon from heat and immediately top each fillet with a generous dollop of the mustard herb butter. Let rest for 1-2 minutes to allow butter to melt. Serve with lemon wedges on the side.

Frequently asked questions

How long does Pan-Roasted Salmon with Mustard Herb Butter take to make?

Total time is about 15 minutes (5 min prep + 10 min cook). Most home cooks find this fits comfortably into a weeknight; double the batch on Sunday for two dinners.

How do I store leftover Pan-Roasted Salmon with Mustard Herb Butter?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish). Store any fresh salsa or citrus-based garnish in a separate container — it keeps for up to 2 days. Freeze cooked fish (without fresh garnishes) for up to 3 months; thaw overnight in the fridge and reheat gently at 275°F until just warmed through to preserve texture.

Can I substitute ingredients in Pan-Roasted Salmon with Mustard Herb Butter?

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-Roasted Salmon with Mustard Herb Butter 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.
