30-Minute Grilled Chilean Sea Bass
Pan-seared Chilean sea bass with crispy skin and tender, flaky flesh, finished with a bright garlic butter sauce infused with lemon, capers, and fresh parsley. This restaurant-quality dish delivers buttery richness balanced by acidic white wine vinegar and red pepper heat. The key to success is scoring the skin to prevent curling and using high heat to achieve a golden crust while keeping the interior moist. Perfect for weeknight dinners or impressing guests, this elegant protein cooks in under 20 minutes. The vibrant sauce, made while fish cooks, combines melted butter with minced garlic, lemon zest, and briny capers for complexity. This version prioritizes simplicity and technique over complicated steps, letting the fish and bold flavors shine without unnecessary embellishment.

Tips
Score the skin in a criss-cross pattern before cooking. This allows heat to penetrate evenly, prevents the skin from contracting and curling upward, and creates more surface area for browning and crisping.
Make the garlic butter sauce while fish cooks to save time. Letting it cool at room temperature allows flavors to meld without cooking off the delicate lemon and fresh parsley notes.
Pat fish completely dry before oiling and seasoning. Excess moisture prevents proper browning and a crispy skin, the textural hallmark of this dish.
Good to Know
Leftovers keep refrigerated in an airtight container for up to 2 days. Reheat gently in a 350F oven for 8-10 minutes to avoid drying the fish. Sauce can be refrigerated separately for 3 days and warmed over low heat.
Prepare spice mixture and chop all ingredients up to 2 hours ahead. Make sauce up to 1 hour before serving and store at room temperature. Do not cook fish until ready to serve.
Serve with lemon wedges, steamed vegetables like asparagus or broccoli, and crusty bread to soak up sauce. Pairs with crisp white wine such as Sauvignon Blanc or Vermentino.
Common Mistakes
Skip the skin scoring to avoid curled, contracted edges that cook unevenly and look unfinished
Don't skip patting fish dry to avoid steam that prevents skin from crisping properly
Remove sauce from heat after 2 minutes to avoid cooking off fresh lemon and parsley aromas

FAQ
Can I use a stovetop cast iron pan instead of a grill?
Yes. Heat cast iron over medium-high heat until a drop of water sizzles on contact. Cook skin-side up for 7 minutes, then flip and cook 7 minutes more. Cast iron browns the skin even more effectively than grill grates.
What if I don't have Chilean sea bass?
Halibut, cod, or striped bass work well. Cod is more delicate, so reduce cooking time by 1-2 minutes per side. Halibut matches sea bass almost identically in texture and cooking time, making it the best substitute.
Can I freeze leftovers?
Fish freezes well up to 3 months. Store cooled fish and sauce separately in airtight containers. Thaw overnight in the refrigerator. Reheat gently at 350F for 10-12 minutes. Sauce can be frozen separately for up to 2 months.
