Instructions

  1. Step 1: Pat dry 4 sea bass filets (6 oz each) and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat.
  2. Step 2: Place the filets skin-side down in the hot skillet and cook for 4-5 minutes without moving until the skin is crisp and golden brown.
  3. Step 3: Flip the filets carefully and cook for an additional 2-3 minutes until the fish is opaque and flakes easily with a fork. Remove filets to a warm plate.
  4. Step 4: Reduce heat to medium-low and add 6 tbsp unsalted butter to the skillet. Allow butter to melt and foam, swirling occasionally, until it turns golden brown and smells nutty, about 3-4 minutes.
  5. Step 5: Add 3 fresh thyme sprigs, 1 tsp lemon zest, and 2 tbsp lemon juice to the brown butter. Stir for 30 seconds, then remove from heat.
  6. Step 6: Pour the herb-infused brown butter sauce over the sea bass filets and garnish with 2 tbsp chopped fresh parsley before serving.

Frequently asked questions

How long does Pan-Seared Sea Bass with Herb-Infused Brown Butter Sauce take to make?

Total time is about 22 minutes (10 min prep + 12 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-Seared Sea Bass with Herb-Infused Brown Butter Sauce?

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-Seared Sea Bass with Herb-Infused Brown Butter Sauce?

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 Sea Bass with Herb-Infused Brown 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.
