Grilled Branzino with Lemon Recipe High-Protein

Recipe by Pedro M. A. Neves

This Italian-inspired grilled branzino with lemon is a lean, elegant protein dish that delivers restaurant-quality flavor in under 30 minutes. Fresh whole branzino fillets are seasoned simply with herbs, olive oil, and bright lemon, then grilled to perfection for a flaky, tender result. High in protein and low in calories, this Mediterranean main is ideal for fitness-focused meals without compromising taste.

Ingredients

• 2 whole branzino fish (400g / 14 oz each), cleaned and gutted
• 3 tablespoons extra-virgin olive oil
• 2 lemons, divided (1 sliced, 1 for juice)
• 4 cloves garlic, thinly sliced
• 2 sprigs fresh rosemary
• 2 sprigs fresh thyme
• 1 teaspoon sea salt
• 0.5 teaspoon black pepper
• 0.25 teaspoon red pepper flakes

Instructions

1. Pat the cleaned branzino dry with paper towels inside and out. This ensures better browning and crispier skin on the grill.

2. Score the skin of each fish diagonally 3 times on each side, cutting about 1/4 inch deep. This allows seasoning to penetrate and promotes even cooking.

3. Stuff each fish cavity with 1 lemon slice, 2 garlic slivers, 1 rosemary sprig, and 1 thyme sprig, dividing evenly between both fish.

4. Brush both sides of each fish generously with olive oil (about 1.5 tablespoons per fish). Season inside and outside with salt, black pepper, and red pepper flakes.

5. Preheat grill to medium-high heat (200°C / 400°F). Oil the grill grates lightly with a folded paper towel dipped in oil to prevent sticking.

6. Place fish directly on grill grates and cook for 5-6 minutes without moving. The skin should char slightly and separate easily from the grill.

7. Carefully flip the fish using two spatulas or fish turner, supporting the underside. Grill for another 5-6 minutes until the flesh is opaque and flakes easily with a fork at the thickest point.

8. Transfer grilled branzino to a serving platter. Squeeze fresh lemon juice over both fish and let rest for 2 minutes before serving.

Substitutions

• Branzino can be replaced with sea bass or halibut for similar white fish texture and mild flavor
• Use dried herbs (0.5 teaspoon each of dried rosemary and thyme) if fresh herbs are unavailable
• Substitute olive oil with avocado oil for a higher smoke point alternative
• Replace fresh lemon with fresh lime for a different citrus profile

Tips

• Do not move the fish on the grill during the first side—this allows the skin to crisp and develop char marks without sticking
• Let your grill preheat fully and oil grates well; branzino skin sticks easily to dry or cool grates
• Use a fish thermometer to check doneness: internal temperature should reach 63°C (145°F) at the thickest part near the backbone
• For serving, place lemon wedges alongside and drizzle any pan juices over the fish for added moisture and flavor

Branzino al forno or grilled branzino is a cornerstone of Italian Mediterranean cuisine, particularly along the Adriatic and Mediterranean coasts where fresh sea bass is abundant. The simplicity of preparation—relying on the quality of the fish, olive oil, and lemon—reflects the Italian philosophy of letting premium ingredients speak for themselves.
