Oven Baked Mediterranean Branzino Ingredients
For the Fish
• Whole Branzino Fish – The star of the dish; provides a light, flaky texture. Ask your fishmonger to clean, gut, and scale it for convenience.
• Melted Butter (4 Tbsp.) – Adds richness and enhances flavors; can be substituted with olive oil for a dairy-free option.
• Olive Oil (2 Tbsp. + 2 Tbsp. for pan) – Essential for moisture and flavor; can swap with another neutral oil if desired.
For the Seasoning
• Garlic Powder (1 tsp.) – Imparts savory flavor; can replace with fresh minced garlic (1 clove).
• Dried Oregano (1 tsp.) – Brings Mediterranean flavor; marjoram can be a suitable substitute.
• Paprika (1 tsp. + additional for dusting) – Adds mild warmth and color; smoked paprika can offer a different flavor profile.
• Squeezed Lemon Juice (3 Tbsp.) – Brightens the dish; fresh lemon zest can enhance lemon flavor.
• Sea Salt and Pepper – Essential for seasoning; adjust to taste.
For the Stuffing & Garnish
• Garlic Cloves (4, minced) – Fresh garlic adds intensity; can omit if preferring a milder flavor.
• Onion (1, sliced & additional for cavity) – Contributes sweetness and flavor; shallots can be a milder alternative.
• Lemons (2, sliced) – Used for flavoring the fish and for garnish.
• Dry Parsley – Used for garnish; fresh herbs like dill or basil can substitute.
For the Sides
• White Wine or Chicken Broth (1/2 cup) – Keeps fish moist while adding depth; use vegetable broth for a non-meat option.
• Potatoes – Thinly sliced (cubed 1/2 inch), acts as a hearty side; any waxy potatoes work well (e.g., Yukon Gold).
• Bell Peppers – Thinly sliced to add color and sweetness; zucchini or asparagus can be great alternatives.
Step‑by‑Step Instructions for Oven Baked Mediterranean Branzino (Sea-Bass)
Step 1: Preheat the Oven
Start by preheating your oven to 400°F (200°C). This ensures it reaches the optimal temperature for baking the Oven Baked Mediterranean Branzino. While the oven warms up, gather your ingredients and prepare your baking tray by lightly greasing it with olive oil to prevent sticking.
Step 2: Prepare the Branzino
Rinse the whole Branzino under cold water and pat it dry using paper towels. Ensuring the fish is properly dried will help achieve that crispy skin. Once dried, make three or more diagonal slits on both sides of the fish. This helps the seasoning penetrate evenly and allows for even cooking throughout.
Step 3: Mix the Seasoning
In a small bowl, combine the melted butter, olive oil, sea salt, pepper, garlic powder, dried oregano, and lemon juice to create a delicious seasoning mix. Use a whisk or fork to blend the mixture well. This flavorful blend now awaits to enhance the taste of your Oven Baked Mediterranean Branzino on both sides.
Step 4: Season the Fish
Carefully brush the seasoning mix over the Branzino, making sure to coat both sides and the slits thoroughly. Don’t forget to also season the inside of the fish. This step is crucial for infusing flavor into the delicate flesh, so take your time to brush it generously.
Step 5: Stuff the Fish
Take the minced garlic, sliced onion, and lemon slices, and stuff them into the cavity of the fish. This adds aromatic flavors as the fish bakes. Make sure it’s filled but not overflowing, allowing the edges to seal and hold in the delicious moisture while baking.
Step 6: Arrange the Vegetables
On your prepared baking tray, arrange the sliced bell peppers and cubed potatoes around the seasoned fish. The veggies will cook alongside the fish, soaking up its flavors and making for a vibrant presentation. Ensure they are evenly spaced for even cooking.
Step 7: Add Liquid
Pour the white wine or chicken broth over the vegetables around the fish. This will help maintain moisture during baking and encourage the vegetables to cook perfectly. Take a moment to enjoy the delightful aroma as everything begins to come together.
Step 8: Dust with Seasoning
Sprinkle any remaining seasoning mix over the vegetables. This adds an extra layer of flavor that will enhance the dish’s overall taste. Visually, this will also give your Oven Baked Mediterranean Branzino an appetizing, colorful appearance.
Step 9: Bake the Dish
Place the baking tray in the preheated oven and bake uncovered for approximately 30 minutes. You’ll know it’s done when the fish is flaky and the potatoes are tender. Keep an eye on it, as cooking times can vary depending on the size of your Branzino.
Step 10: Serve and Garnish
Once out of the oven, drizzle the baked fish with additional lemon juice for a fresh burst of flavor. Garnish with some freshly chopped herbs for an enticing finish. This step adds a beautiful pop of color that makes your Oven Baked Mediterranean Branzino ready for serving.

Oven Baked Mediterranean Branzino (Sea-Bass) Recipe FAQs
What should I look for when selecting fresh Branzino?
When selecting Branzino, look for fish that has shiny, clear eyes, firm flesh, and bright, vibrant skin. The fish should smell fresh, like the sea, without any strong or unpleasant odors.

How should I store leftovers of the Oven Baked Mediterranean Branzino?
Store leftover Oven Baked Mediterranean Branzino in an airtight container in the fridge for up to 3 days. Make sure the fish has cooled to room temperature before sealing to prevent condensation from making it soggy. Reheat gently in the oven at 350°F (175°C) to maintain its flaky texture.

What if my fish seems undercooked? How can I check?
No worries! If you suspect the fish is undercooked, use a meat thermometer to check the internal temperature. It should reach 145°F (63°C) for safe consumption.
