01 - Pat sea bass fillets dry with paper towels and season both sides with kosher salt and freshly ground black pepper.
02 - Heat olive oil in a large nonstick or stainless-steel skillet over medium-high heat.
03 - Place fillets skin-side down in the skillet, press gently with a spatula, and sear for 3 to 4 minutes until skin is crispy and golden brown.
04 - Flip fillets and cook for 2 to 3 minutes more until flesh is just opaque and cooked through. Transfer fillets to a warm plate and tent with foil.

08 - Remove from heat, incorporate fresh parsley, and season with salt and pepper to taste.
09 - Spoon lemon caper sauce over sea bass fillets and serve immediately with preferred side dishes.
