Ingredients
Sea Bass & Sear
- 4 Chilean sea bass fillets (6 oz / 170 g each), skin-on or skinless
- 2 tbsp neutral oil (grapeseed or avocado)
- 2 tbsp unsalted butter
- 1 tsp fine sea salt
- ½ tsp white pepper (or black)
Lemon-Caper Beurre Blanc
- ½ cup (120 ml) dry white wine (Sauvignon Blanc)
- 2 tbsp fresh lemon juice
- 1 small shallot, minced
- ½ cup (113 g) cold unsalted butter, cubed
- 2 tbsp capers, rinsed
- 1 tsp lemon zest
- ¼ tsp fine sea salt
For Serving
- Microgreens or parsley
- Lemon wedges
- Mashed potatoes or asparagus
Essential Tools and Equipment
- Heavy skillet (cast-iron or stainless)
- Fish spatula
- Small saucepan
- Whisk
- Instant-read thermometer
Step-by-step process
- Prep fish and sauce base: Pat fillets completely dry with paper towels—moisture prevents sear. Season both sides with salt and white pepper. Let sit 10 minutes at room temp—cooks evenly. Mince shallot finely; zest and juice lemon.
- Start beurre blanc: In a small saucepan over medium heat, combine wine, lemon juice, and shallot. Simmer 5–7 minutes until reduced to 2 tbsp—syrupy glaze. Reduce the heat to the lowest.
- Sear sea bass: Heat oil in skillet over medium-high until shimmering (400 °F / 200 °C). Place fillets presentation-side down—don’t crowd. Sear 4–5 minutes undisturbed—golden crust forms. Flip gently with a fish spatula.
- Butter baste: Add butter to the skillet; tilt the pan. Spoon foaming butter over fillets 1–2 minutes—nutty aroma signals doneness. Internal temp should hit 130–135 °F (54–57 °C)—carryover finishes to 140 °F.
- Finish sauce: Off heat, whisk cold butter cubes into reduction one at a time—sauce emulsifies to creamy gloss. Stir in capers, zest, and salt. If it breaks, whisk in 1 tsp warm water. Keep warm over a double boiler.
- Rest fish: Transfer fillets to a paper towel for 1 minute—crust sets, juices redistribute.
- Plate elegantly: Spoon beurre blanc pool on warm plates. Place sea bass atop—crust up. Garnish with microgreens, lemon curl.
- Serve immediately: Pair with chilled white wine. Flake with fork—silky texture shines.
Mistakes to avoid
- Wet fish: Soggy sear—pat dry twice.
- Overcooking: 10-minute rule (per inch thickness)—pull at 130 °F.
- Hot pan butter: Burns instantly—add after flip.
- Broken sauce: Cold butter + low heat = emulsion.
- Crowding pan: Steams instead of sears—cook in batches.
Variations of the Best Chilean Sea Bass
- Miso Glaze: 2 tbsp miso + mirin; broil 2 minutes.
- Herb Crust: Panko + parsley + lemon; press on top.
- Oven Only: 400 °F 12–15 minutes on parchment—no flip.
- Spicy Kick: Chili crisp drizzle post-sear.
- Skinless Hack: Dust with Wondra flour for extra crisp.
Tips for better storage
- Refrigerator: Cool; airtight up to 2 days. Reheat 275°F 8 minutes.
- Freezer: Not ideal—texture suffers; max 1 month.
- Reheating: Low oven or sous vide 120°F—preserves flake.
- Make-ahead: Sauce day before; re-whisk gently.
- Portion control: 6 oz per person—rich fish satisfies.
