Instructions

Step 1: Prepare the Fish

Rinse the sea bass under cold water and pat it completely dry with paper towels.

If using whole fish, make 3–4 shallow diagonal slashes on each side to help the seasoning penetrate.

Season the fish inside and out with salt and black pepper.

Step 2: Prepare the Marinade

In a bowl, combine:

  • Olive oil
  • Garlic
  • Lemon juice
  • Lemon zest
  • Oregano
  • Thyme
  • Rosemary
  • Parsley
  • Paprika
  • Red pepper flakes (optional)

Mix well.

Brush the marinade generously over both sides of the fish and inside the cavity if using whole fish.

Let it marinate for 20 minutes.

Step 3: Stuff the Fish

Fill the cavity with:

  • Lemon slices
  • Garlic slices
  • Parsley
  • Rosemary
  • Thyme

This infuses the fish with fresh citrus and herbal aromas while baking.

Step 4: Prepare the Baking Dish

Preheat the oven to 400°F (200°C).

Lightly grease a baking dish with olive oil.

If using vegetables, spread them evenly in the bottom of the dish, drizzle with olive oil, and season with salt and pepper.

Place the marinated sea bass on top.

Step 5: Bake

Bake uncovered for 25–30 minutes, depending on the size of the fish.

For fillets, bake for 12–15 minutes.

The fish is ready when:

  • The flesh is opaque.
  • It flakes easily with a fork.
  • The internal temperature reaches 145°F (63°C).

Step 6: Optional Broil

For lightly browned skin, broil the fish for 2–3 minutes at the end of baking. Watch carefully to prevent burning.

Step 7: Serve

Transfer the fish to a serving platter.

Spoon the pan juices over the top.

Garnish with fresh parsley, lemon wedges, and a drizzle of olive oil.

Expert Tips

  • Pat the fish completely dry before seasoning for the best texture.
  • Fresh lemon juice provides brighter flavor than bottled juice.
  • Avoid overcooking, as sea bass can dry out quickly.

  • Bake vegetables alongside the fish for a complete one-pan meal.

Frequently Asked Questions

Can I use frozen sea bass?

Yes. Thaw it completely in the refrigerator and pat it dry before seasoning and baking.

Can I use fillets instead of whole fish?

Absolutely. Fillets cook faster and are easier to serve, typically requiring only 12–15 minutes in the oven.

Do I need to cover the fish while baking?

No. Baking uncovered allows the surface to brown lightly. If the fish begins to brown too quickly, loosely cover it with foil near the end of cooking.

What vegetables pair best with sea bass?

Baby potatoes, asparagus, zucchini, bell peppers, onions, cherry tomatoes, broccoli, and green beans all complement the mild flavor of sea bass.

How do I know when the fish is done?

The flesh should be opaque, flake easily with a fork, and reach an internal temperature of 145°F (63°C).
