What is Branzino?
Branzino, also known as European sea bass or loup de mer, is a mild, flaky white fish commonly found in most Mediterranean dishes. This fish has a delicate, slightly sweet taste and cooks beautifully whole, making it a popular choice for roasted fish recipes.
If you’ve never cooked a whole fish before, it may look intimidating, but it’s actually one of the simplest and most elegant ways to prepare fish. When roasted, the skin crisps up while the inside stays tender, juicy, and full of flavor.
Ingredients
- Whole Branzino Fish – The star of the dish; a mild, flaky white fish with a clean, slightly sweet flavor
- Truffle Oil – Adds a luxurious, earthy richness that elevates the fish. If you do not have truffle oil, you can substitute with olive oil.
- Truffle Salt – Enhances flavor with a subtle gourmet touch. If you do not have truffle salt, you can substitute with sea salt.
- Ground Black Pepper – Adds gentle heat and balances the richness
- Fresh Oregano – Brings a bold, herbaceous Mediterranean flavor
- Fresh Parsley – Adds freshness and brightness
- Fresh Rosemary – Infuses the fish with a deep, aromatic note
- Sweet Onion (sliced) – Adds natural sweetness and depth as it roasts
- Lemon wedges – Brightens the dish with acidity and enhances the fish’s natural flavor
- Butter – Keeps the fish moist and adds richness
- Cooking twine – Helps secure the stuffing inside the cavity of the fish
Why lemon and herbs work so well:
Lemon juice and fresh herbs are essential in Mediterranean cooking because they enhance the natural flavor of the fish without overpowering it. The acidity from lemon balances the richness of butter and oil, while herbs like parsley, oregano, and rosemary bring freshness and depth.
How to Roast Branzino
This recipe comes together in just four easy steps:
STEP 1: Prep Branzino – Set your oven to 400°F and place the rack in the center of the oven. Slice lemons and onion and set aside. Take a baking sheet and place some of the sliced onions on the baking sheet to act as a bed for the fish while cooking. Ensure fish has scales removed and is gutted.
STEP 2: Season Branzino– Wash and pat the fish dry with paper towels. Using a sharp knife, cut slits along both sides of the fish to allow seasoning to cook well during roasting. Brush the outside of the fish with truffle oil, then season generously with truffle salt and black pepper, making sure to get inside the slits. Fill the cavity of the fish with lemon wedges, sliced sweet onion, fresh herbs, and butter. Add a light sprinkle of salt inside as well.
STEP 3: Use Twine on Branzino – Use cooking twine to gently secure the fish so the stuffing stays in place. Place on a baking sheet (you can also line your baking dish with parchment paper for easy cleanup).
STEP 4: Roast the Branzino – Roast for 15-17 minutes until the fish is opaque and flakes easily. Finish with a quick broil for 1-2 minutes to crisp the skin and brown. Transfer to a serving platter, garnish with extra lemon wedges, and enjoy!
Tips for Cooking Branzino
- Always start with fresh fish for the best flavor. You can tell if a fish is fresh by the smell and its eyes. The fish should not smell fishy.
- Pat the fish dry to help achieve crispy skin during the roasting process.
- Don’t skip adding slits onto the fish. This will help the seasoning penetrate the fish during the cooking process.
- Cook at high heat to get that perfect roasted texture.
- This Branzino is done when it flakes easily and reaches about 145°F internally.
- Let the fish rest for a couple minutes before serving.
Storage
- Store leftovers in an airtight container in the refrigerator for up to 2 days
- Reheat gently in the oven at 300°F (150°C) to avoid drying out
- Remove the fish from the bones before storing for easier reheating

- 1 tsp Black Pepper
- 6 sprigs Fresh Oregano
- 6 sprigs Fresh Parsley
- 2 sprigs Fresh Rosemary
- ½ Sweet Onion, sliced
- 1 Lemon, sliced into wedges
- 2 tbsp Butter
Instructions
- Set your oven to 400°F (200°C) and place the rack in the center of the oven. Slice lemons and onion and set aside. Take a baking sheet and place some of the sliced onions on the baking sheet to act as a bed for the fish while cooking.
- Wash and pat the fish dry with paper towels. Using a sharp knife, cut slits along both sides of the fish to allow seasoning to cook well during roasting. Brush the outside of the fish with truffle oil, then season generously with truffle salt and black pepper, making sure to get inside the slits.

Notes
- Pat the fish completely dry – This is key to getting that beautifully crisp skin when roasting.
- Score the fish deeply but not through the bone – The slits help the seasoning and flavor penetrate the fish evenly.
- Don’t overstuff the cavity – Keep it lightly filled so the fish cooks evenly all the way through.
- Use kitchen twine for a polished presentation – Tying the fish helps hold everything in place and gives it that restaurant-style look.
- Cook time depends on size – Smaller fish may cook closer to 12-14 minutes, while larger ones take 15-17 minutes.
- Finish with a quick broil – This step crisps the skin and adds that golden, slightly charred finish.
- Check for doneness properly – The fish should flake easily with a fork and reach an internal temp of 145°F (63°C).
