Ingredients

• 2 Chilean seabass fillets (about 6 oz each)
• 3 tbsp butter (for sauce) + 2 tbsp butter (for searing)
• 2 tbsp fresh lemon juice
• 1 tbsp capers, drained and rinsed
• 1 large shallot, finely minced
• 4 garlic cloves, finely minced
• 1 tsp Italian herb seasoning
• 1 tsp sea salt
• 1 tsp freshly cracked black pepper
• Optional: chopped parsley or microgreens for garnish

Substitutions

• If you are avoiding garlic, reduce or omit the garlic.
• For a dairy-free option, use extra-virgin olive oil or a plant-based butter substitute in place of butter.

Instructions

Step 1 — Prep

Have all ingredients measured and ready. Mince the shallot and garlic, rinse and drain the capers, and juice the lemon.

Step 2 — Sear the seabass

1. Heat a large nonstick or well-seasoned skillet over medium-high heat until hot.
2. Add 2 tablespoons of butter and let it foam but not brown.
3. Pat the seabass dry, season with salt, pepper, and the Italian herb seasoning. Place fillets in the pan, fat side down first. Sear undisturbed for about 5–6 minutes until the bottom is golden and a crust forms.
4. Carefully flip the fillets and cook the other side briefly until the fish is opaque and flakes easily. Remove the fillets to a warm plate while you make the sauce.

Pro tip: A hot pan and dry fish are essential for a crisp, golden exterior.

Step 3 — Lemon caper butter sauce

1. In the same skillet, reduce heat to medium and add 3 tablespoons of butter.
2. Sauté the minced shallot and garlic for about 1–2 minutes until fragrant and softened, taking care not to burn the garlic.
3. Stir in the lemon juice and capers. Season with salt and pepper, and add the Italian herb seasoning. Let the sauce simmer briefly so it thickens slightly and the flavors meld.

Step 4 — Plate and serve

Spoon the lemon caper butter over the seabass fillets, garnish with chopped parsley or microgreens if desired, and serve immediately.

Notes & Tips for Perfect Seabass

• Temperature is key: A hot skillet yields a golden crust and prevents sticking.
• Don’t overcook: Seabass cooks quickly; it should be opaque and flake with a fork.
• Dry the fillets: Pat fish dry with paper towels before searing to ensure a good crust.
• Fresh ingredients: Fresh lemon and garlic deliver brighter, cleaner flavor than bottled substitutes.
• Adjust seasoning: Taste the sauce and add a pinch more salt or lemon if needed to balance the butter and capers.

Serving Suggestions

This lemon caper butter seabass benefits from light, fresh sides. Try roasted asparagus, sautéed green beans, or oven-roasted baby potatoes. A simple lemon rice or herbed cauliflower rice complements the tangy sauce. Finish the meal with a chilled, crisp white wine or a sparkling water with lemon for a refreshing contrast.

Storage and Reheating

Store leftover seabass in an airtight container in the refrigerator for up to two days. To reheat, gently warm in a low oven at 275°F (135°C) for 10–12 minutes, or microwave briefly on low power (1–2 minutes) to avoid drying the fish. Reheat slowly to preserve the sauce’s texture.

Frequently Asked Questions

Can I use frozen seabass?

Yes. Thaw the fish completely in the refrigerator before cooking for even searing and consistent texture.

What can I use instead of capers?

Olives or finely chopped pickles can provide a similar salty, briny note if capers are unavailable.

How do I make this dairy-free?

Use good-quality extra-virgin olive oil or a plant-based butter replacement in both the searing and sauce steps.

Other herbs to try?

Fresh dill, tarragon, or thyme pair nicely with lemon and fish; add a small amount to the sauce to experiment with different flavor profiles.
