Step‑by‑Step Instructions for Restaurant-Style Chilean Sea Bass
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While it heats, pat the Chilean sea bass fillets dry with paper towels. This step is vital to achieving a golden crust. Once dry, season both sides of the fish generously with sea salt and freshly ground black pepper to enhance its natural flavors.
Step 2: Sear the Fillets
In an oven-safe skillet, heat 2 tablespoons of olive oil over medium-high heat. When the oil begins to shimmer, carefully place the seasoned Chilean sea bass fillets skin-side down. Sear the fillets for 3-4 minutes until the skin is golden and crispy, using a spatula to gently press down for an even sear.
Step 3: Add Garlic and Butter
Once the fillets are beautifully seared, carefully flip them over. Immediately add 3 tablespoons of unsalted butter and 3 cloves of minced garlic to the skillet. Allow the butter to melt while spooning it over the fish for 1-2 minutes, infusing the fillets with garlic warmth as it begins to bubble and foam.
Step 4: Incorporate Lemon Zest and Juice
Next, stir in the juice and zest of one lemon, letting the bright citrus notes awaken the flavors of the garlic butter. This vibrant addition elevates your Restaurant-Style Chilean Sea Bass. After mixing, transfer the entire skillet to your preheated oven, allowing the fish to roast for 8-10 minutes until it flakes easily when tested with a fork.
Step 5: Finish and Serve
Once cooked, carefully remove the skillet from the oven. Spoon the luscious garlic butter sauce generously over the fillets, ensuring they are drenched in flavor. For a fresh touch, sprinkle chopped parsley on top before serving. Enjoy your elegant Restaurant-Style Chilean Sea Bass while it’s warm, paired perfectly with your favorite sides!
