Instructions

  1. Step 1: Pat 4 sea bass filets dry with paper towels. Season both sides with 1 tsp salt and 1/2 tsp black pepper.
  2. Step 2: Heat 2 tbsp olive oil in a large non-stick skillet over medium-high heat until shimmering.
  3. Step 3: Add the sea bass filets skin-side down and cook for 4-5 minutes without moving, until the skin is crispy and golden.
  4. Step 4: Carefully flip the filets and cook for another 3 minutes until the fish is opaque and flakes easily.
  5. Step 5: Remove the fish from the skillet and keep warm. Reduce heat to medium and add 4 tbsp unsalted butter and 3 minced garlic cloves to the pan.
  6. Step 6: Stir the butter and garlic together for 1 minute until fragrant. Remove from heat and stir in 2 tbsp fresh lemon juice, 1 tsp lemon zest, and 2 tbsp chopped fresh parsley.
  7. Step 7: Spoon the lemon herb butter sauce over the sea bass and serve immediately.

How do I store leftover Pan-Seared Sea Bass with Lemon Herb Butter Sauce?

Refrigerate in a covered airtight container for up to 3–4 days (FDA FoodKeeper guideline for cooked fish).
