01 - Pat sea bass fillets dry with paper towels. Season both sides evenly with kosher salt and freshly ground black pepper.
02 - Warm olive oil in a large nonstick or stainless-steel skillet over medium-high heat until shimmering.
03 - Place fillets skin-side down, press gently with a spatula, and cook for 3 to 4 minutes until the skin is crisp and golden brown.
04 - Turn fillets over and cook for an additional 2 to 3 minutes until flesh is opaque and cooked through. Transfer to a warm plate and loosely tent with foil.
05 - Reduce heat to medium, add butter to the same skillet, and melt. Add minced garlic and sauté for 30 seconds until aromatic.
06 - Add drained capers, stirring for 1 minute. Pour in white wine or fish stock, scraping up browned bits from the pan bottom.
07 - Stir in lemon juice and zest. Simmer gently for 2 to 3 minutes to slightly reduce and concentrate flavors.
08 - Remove from heat, stir in chopped fresh parsley, and adjust seasoning with salt and pepper to taste.
09 - Ladle the lemon caper sauce over the sea bass fillets immediately. Accompany with sautéed spinach, roasted potatoes, or steamed asparagus as preferred.
