Ingredients

For the Fish

  • 1 whole fish (about 1–1.2 kg), cleaned and scaled
  • 3 tablespoons olive oil
  • 2 lemons (1 sliced, 1 juiced)
  • 4 garlic cloves, minced
  • 2 teaspoons sea salt
  • 1 teaspoon freshly ground black pepper
  • 1 teaspoon paprika
  • 1 teaspoon dried oregano
  • 1 teaspoon fresh thyme leaves
  • 2 tablespoons chopped fresh parsley

For Stuffing the Fish

  • Lemon slices
  • Fresh parsley sprigs
  • Fresh dill
  • Fresh thyme
  • Garlic slices

Optional Basting Butter

  • 2 tablespoons melted butter
  • 1 teaspoon chopped parsley
  • ½ teaspoon paprika

Kitchen Equipment

  • Outdoor grill or grill pan
  • Fish grilling basket (recommended)
  • Tongs
  • Basting brush
  • Sharp knife
  • Mixing bowl
  • Instant-read thermometer (optional)

Step 1: Prepare the Fish

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

Using a sharp knife, make 3–4 shallow diagonal slashes on each side of the fish. This helps the seasoning penetrate and promotes even cooking.

Step 2: Make the Marinade

In a bowl, combine:

  • Olive oil
  • Lemon juice
  • Garlic
  • Salt
  • Black pepper
  • Paprika
  • Oregano
  • Thyme
  • Chopped parsley

Mix well.

Rub the marinade over the entire fish, including inside the cavity and into the slashes.

Stuff the cavity with:

  • Lemon slices
  • Parsley sprigs
  • Dill
  • Garlic slices
  • Fresh thyme

Cover and refrigerate for 30 minutes.

Step 3: Preheat the Grill

Heat the grill to medium-high heat (200–220°C / 390–425°F).

Clean the grill grates thoroughly and oil them lightly to help prevent sticking.

If using a fish basket, lightly oil it as well.

Step 4: Grill the Fish

Place the fish directly on the grill or inside a fish basket.

Cook for 8–10 minutes on the first side without moving it.

Carefully flip the fish using two spatulas or the fish basket.

Grill the second side for another 8–10 minutes.

During the final few minutes, brush with the optional herb butter for extra richness and color.

The fish is done when:

  • The flesh flakes easily with a fork.
  • The skin is crisp and lightly charred.
  • The internal temperature reaches 63°C (145°F) at the thickest part.

Step 5: Rest and Serve

Transfer the grilled fish to a serving platter.

Let it rest for 5 minutes before serving.

Garnish with:

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

Serving Suggestions

Grilled Whole Fish pairs beautifully with:

  • Grilled vegetables
  • Garlic butter potatoes
  • Lemon herb rice
  • Couscous
  • Greek salad
  • Coleslaw
  • Roasted asparagus
  • Crusty bread
  • Tzatziki or garlic aioli

Chef's Tips

  • Choose the freshest fish available for the best flavor and texture.
  • Pat the fish dry before seasoning to help the skin crisp.
  • Oil both the grill grates and the fish lightly to reduce sticking.
  • Avoid flipping the fish too early—wait until it releases naturally from the grill.
  • A fish basket makes turning the fish much easier and helps keep it intact.

Delicious Variations

Microwave

Heat gently on medium power in short intervals to avoid drying out the fish.

Frequently Asked Questions

How do I know when the fish is cooked?

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

Can I cook the fish in the oven instead?

Yes. Bake at 200°C (400°F) for about 20–30 minutes, depending on the size of the fish.

Should I remove the skin before grilling?

No. The skin helps protect the flesh from direct heat, keeps the fish moist, and becomes deliciously crispy.

Which charcoal is best for grilling fish?

Natural hardwood charcoal provides a clean, smoky flavor, while lump charcoal reaches high heat quickly and works especially well for whole fish.

Can I use frozen whole fish?

Yes. Thaw it completely in the refrigerator, rinse, and pat it dry thoroughly before seasoning and grilling.
