Ingredients

For the Fish

  • 1 whole fish (about 1–1.2 kg) or 4 large fish fillets
  • 3 tablespoons extra virgin olive oil
  • 2 tablespoons fresh lemon juice
  • 4 garlic cloves, minced
  • 2 teaspoons sea salt
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon paprika
  • 1 teaspoon onion powder (optional)

Fresh Herbs

  • 2 tablespoons chopped parsley
  • 1 tablespoon chopped dill
  • 1 tablespoon chopped thyme
  • 1 tablespoon chopped rosemary
  • 1 tablespoon chopped basil

Optional Aromatics

  • Lemon slices
  • Cherry tomatoes
  • Thinly sliced onion
  • Whole garlic cloves
  • Fresh rosemary sprigs

For Garnish

  • Fresh parsley
  • Dill
  • Lemon wedges
  • Extra virgin olive oil (optional)

Kitchen Equipment

  • Roasting pan or baking tray
  • Parchment paper
  • Mixing bowl
  • Pastry brush
  • Sharp knife
  • Instant-read thermometer (optional)

Step 1: Prepare the Fish

If using a whole fish, ensure it has been cleaned and scaled.

Rinse under cold water and pat completely dry with paper towels.

For a whole fish, make 3–4 shallow diagonal slashes on each side to help the marinade penetrate.

Step 2: Make the Herb Marinade

In a bowl, combine:

  • Olive oil
  • Lemon juice
  • Garlic
  • Salt
  • Black pepper
  • Paprika
  • Onion powder (optional)
  • Chopped parsley
  • Dill
  • Thyme
  • Rosemary
  • Basil

Mix well.

Rub the marinade evenly over the fish, inside the cavity if using a whole fish, and into any slashes.

If desired, stuff the cavity with lemon slices and fresh herb sprigs.

Marinate for 20 minutes.

Step 3: Prepare for Roasting

Preheat the oven to 200°C (400°F).

Line a roasting pan with parchment paper or lightly grease it.

Arrange optional vegetables such as cherry tomatoes, sliced onion, and whole garlic cloves around the fish for extra flavor.

Step 4: Roast the Fish

Place the fish in the preheated oven.

Roast for:

  • Whole fish: 30–35 minutes
  • Thick fillets: 20–25 minutes

The fish is cooked when:

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

For a lightly browned finish, switch the oven to broil for the last 2–3 minutes, keeping a close eye on the fish.

Step 5: Rest and Serve

Allow the fish to rest for 5 minutes after removing it from the oven.

Transfer to a serving platter and garnish with:

  • Fresh parsley
  • Dill
  • Lemon wedges
  • A light drizzle of extra virgin olive oil

Serve immediately.

Serving Suggestions

  • Roasted baby potatoes
  • Garlic mashed potatoes
  • Lemon herb rice
  • Couscous
  • Steamed green beans
  • Roasted asparagus
  • Grilled zucchini
  • Mixed green salad

Chef's Tips

  • Pat the fish dry before seasoning to encourage better browning.
  • Fresh herbs provide the brightest flavor, but dried herbs can be used in smaller amounts if fresh aren't available.
  • Avoid overcooking, as fish continues to cook slightly after being removed from the oven.
  • Roasting vegetables alongside the fish creates an easy one-pan meal.
  • An instant-read thermometer helps ensure perfectly cooked fish every time.

Frequently Asked Questions

Can I use frozen fish?

Yes. Thaw it completely in the refrigerator, then pat it dry thoroughly before marinating and roasting.

Should I roast fish covered or uncovered?

Roast it uncovered to encourage light browning. If the fish begins to brown too quickly, loosely tent it with foil for the remainder of the cooking time.

How do I know when the fish is fully cooked?

The flesh should be opaque and flake easily with a fork. An instant-read thermometer inserted into the thickest part should read 63°C (145°F).

Can I use dried herbs?

Yes. Use about one-third the amount of dried herbs compared to fresh, as dried herbs have a more concentrated flavor.

Which side dishes work best?

Roasted potatoes, herb rice, grilled vegetables, steamed greens, couscous, and crisp salads all complement Herb Roasted Fish beautifully.
