Ingredients

Instructions

  1. Step 1: Pat dry 4 salmon fillets (6 oz each) and season both sides evenly with 1 tsp kosher salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering. Place the salmon fillets skin-side down and cook undisturbed for 5-6 minutes until the skin is crisp and the salmon is cooked about two-thirds through.
  3. Step 3: Flip the fillets carefully and cook for another 2-3 minutes until the salmon is opaque and flakes easily. Transfer salmon to a warm plate.
  4. Step 4: Reduce heat to medium-low and add 3 tbsp unsalted butter to the same skillet. Once melted, stir in 2 tbsp Dijon mustard, 2 tbsp fresh lemon juice, and 1 minced garlic clove. Cook the sauce for 1-2 minutes, stirring constantly until fragrant and slightly thickened.
  5. Step 5: Remove from heat and stir in 1 tbsp chopped fresh parsley. Spoon the sauce generously over the salmon before serving.

How do I store leftover Pan-Seared Salmon with Dijon Mustard and Lemon Butter Sauce?

Can I substitute ingredients in Pan-Seared Salmon with Dijon Mustard and Lemon Butter Sauce?

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 Salmon with Dijon Mustard and Lemon Butter Sauce 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.
