Instructions

  1. Step 1: Pat dry 4 Chilean sea bass fillets (6 oz each) and season both sides with 1 tsp sea salt and 1/2 tsp black pepper.
  2. Step 2: Heat 3 tbsp olive oil in a large nonstick skillet over medium-high heat. Place fillets skin-side down and sear for 5 minutes until the skin is crisp and golden.
  3. Step 3: Carefully flip fillets and cook an additional 3-4 minutes until the fish flakes easily with a fork.
  4. Step 4: In a small bowl, whisk together 2 tbsp lemon juice, 2 tbsp orange juice, 2 tbsp chopped fresh basil, 1 tsp honey, 1 tbsp minced shallot, and 2 tbsp extra virgin olive oil until emulsified.
  5. Step 5: Spoon the citrus-basil vinaigrette over the cooked sea bass just before serving to add brightness and fresh flavor.

Frequently asked questions

How long does Pan-Seared Chilean Sea Bass with Citrus-Basil Vinaigrette take to make?

Total time is about 20 minutes (10 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-Seared Chilean Sea Bass with Citrus-Basil Vinaigrette?

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 Chilean Sea Bass with Citrus-Basil Vinaigrette?

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 Chilean Sea Bass with Citrus-Basil Vinaigrette 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.
