Ingredients

For the fish:

2 sea bass fillets, skin on (about 6–7 oz / 170–200 g each)
2 tablespoons olive oil
Salt and freshly ground black pepper, to taste

For the lemon butter sauce:

4 tablespoons unsalted butter
1 clove garlic, minced
Juice of 1 lemon
Zest of 1 lemon
1 tablespoon fresh parsley, chopped
Salt and pepper, to taste

Optional garnish: lemon wedges, fresh herbs

Instructions

Preheat your oven to 200°C (400°F).
Pat the sea bass fillets dry with paper towels and season both sides with salt and pepper.
Heat olive oil in an oven-safe skillet over medium-high heat. Place the fillets skin-side down and sear for 2–3 minutes until the skin is crispy.
Flip the fillets and transfer the skillet to the preheated oven. Roast for 5–7 minutes, depending on thickness, until the fish is cooked through and flakes easily with a fork.
While the fish is roasting, prepare the lemon butter sauce. In a small saucepan, melt butter over medium heat. Add garlic and cook for 30 seconds until fragrant. Stir in lemon juice, lemon zest, parsley, salt, and pepper. Remove from heat.
Plate the roasted sea bass fillets and drizzle generously with the lemon butter sauce. Garnish with fresh herbs or lemon wedges if desired.
Serve immediately with your choice of sides.

Tips for the Best Roasted Sea Bass

Dry the skin thoroughly before searing for extra crispiness.
Use fresh lemon juice for a bright, vibrant flavor.
Don’t overcook the fish — it cooks quickly and should be flaky and moist.
For an extra touch, finish with a sprinkle of sea salt just before serving.

Variations

Herb Butter: Add thyme or tarragon to the butter sauce for more depth.
Garlic Lemon Capers: Stir in 1 tablespoon capers for a briny twist.
Pan-Seared Only: Skip the oven and cook entirely on the stovetop for a faster version.
Mediterranean Style: Add cherry tomatoes and olives to the skillet while roasting.

Frequently Asked Questions

Can I use other types of fish?
Yes, halibut, cod, or trout fillets work well. Adjust cooking time based on thickness.

Can I make the lemon butter sauce ahead of time?
Yes, but reheat gently before serving. Fresh parsley can be added after reheating for brightness.

How do I know when the fish is done?
It should flake easily with a fork, and the flesh should be opaque.

Can I pan-sear frozen fillets?
It’s best to thaw first for even cooking and to prevent excess moisture.
