Instructions

  1. Step 1: Pat 4 sea bass fillets dry and season both sides with 1 tsp salt and 1/2 tsp black pepper. Heat 3 tbsp olive oil in a large nonstick skillet over medium-high heat until shimmering.
  2. Step 2: Add sea bass fillets skin-side down and cook for 4-5 minutes without moving until skin is crisp and golden. Flip and cook an additional 3-4 minutes until fish is opaque and flakes easily with a fork.
  3. Step 3: While fish cooks, combine 1 diced ripe avocado, 1/4 cup chopped fresh cilantro, 2 tbsp fresh lime juice, 1/4 tsp red chili flakes, 1/2 cup halved cherry tomatoes, and 2 tbsp finely diced red onion in a bowl. Toss gently to combine.
  4. Step 4: Plate sea bass fillets and spoon the cilantro-lime avocado salsa generously over the top. Serve immediately with lime wedges if desired.

Frequently asked questions

How long does Pan-Seared Sea Bass with Cilantro-Lime Avocado Salsa 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 Sea Bass with Cilantro-Lime Avocado Salsa?

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 Cilantro-Lime Avocado Salsa?

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 Cilantro-Lime Avocado Salsa 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.
