Ingredients You’ll Need :
2 tablespoons olive oil, divided, 1 red onion, chopped, Salt and ground black pepper to taste, 2 whole Branzino (sea bass) fish, cleaned, 4 lemon wedges, divided, 2 sprigs fresh rosemary, 1/2 cup white wine, 1/4 cup lemon juice, 1 tablespoon fresh oregano leaves, 1/4 cup chopped Italian flat-leaf parsley
STEP-BY-STEP INSTRUCTIONS :
Preheat the oven to 325 degrees F (165 degrees C). Drizzle 1 tablespoon olive oil into a large baking pan; add red onion and season with salt and pepper. Place 2 whole branzino fish into the baking pan. Stuff each cavity with 1 lemon wedge, 1 rosemary sprig, and some of the red onion in the pan. Pour white wine and lemon juice over fish and sprinkle with oregano. Drizzle remaining 1 tablespoon olive oil over fish.

Serve fish on a platter; garnish with parsley and 2 lemon wedges.

HOW TO SERVE Mediterranean Branzino
Serve the branzino hot with a squeeze of fresh lemon. For a low carb and gluten free plate, pair the fish with steamed broccoli, sautéed green beans, or a mixed green salad. For a balanced meal, add a small portion of whole grains such as quinoa or a light orzo side. Keep portion sizes moderate: one whole branzino per person is about right for most adults.
Portion control tips:
- Aim for one whole branzino or 4–6 ounces of fish per serving if you serve other sides.
- Fill half your plate with non-starchy vegetables to stay low calorie and high fiber.
- Use one lemon wedge per serving for flavor instead of extra oil or butter.
This dish also makes a great choice when you need a lighter option after a heavy day. If you want a meal that is easy to reheat, it is great for meal prep.
STORAGE & FREEZING : Mediterranean Branzino
Store cooked branzino in an airtight container in the fridge for up to 3 days. To reheat, warm gently in a low oven (300 degrees F / 150 degrees C) for 8–10 minutes or use a covered skillet on low heat. Avoid high heat that dries the fish.
To freeze, wrap each fillet or whole portion tightly in plastic wrap and place in a freezer bag. Freeze up to 2 months for best quality. Thaw in the fridge overnight before reheating gently.
If you plan to use leftovers for meal prep, separate the fish into meal containers with vegetables and a small grain to keep portions balanced. For more low calorie meal ideas that go well with fish, see this light soup option Mediterranean orzo soup which stores well and adds healthy vegetables.
SERVING SUGGESTIONS
- Steamed asparagus and lemon zest for a low carb side.
- Roasted Mediterranean vegetables (zucchini, bell pepper, eggplant) for fiber and color.
- A small serving of quinoa tossed with parsley and lemon for added protein and fiber.
- Cauliflower rice to keep the meal low carb and low calorie.
- A fresh Greek salad for a crunchy, vitamin-rich plate.
Pick one or two sides to keep the meal balanced. For a high protein meal, pair the fish with quinoa or a beans salad. For a lighter option, choose more vegetables and fewer grains.
VARIATIONS
- Healthier version: Use less oil and add extra lemon and fresh herbs for flavor. Roast on a wire rack in the pan so excess juices drain away. This keeps the fish lower calorie and still moist.
- High-protein / low-carb version: Serve the branzino with a large green salad and roasted Brussels sprouts or cauliflower rice. This keeps carbs low and protein high for a good for weight loss plan.
- Air fryer or oven-baked version: For an air fryer, gut and score the fish, brush with oil, and air fry at 360°F (180°C) for 10–12 minutes until opaque and flaky. If you prefer oven-baked, use the method above at 325°F as directed. Both methods give a nicely cooked fish; the air fryer gives a slightly crisper skin.
These changes let you adjust the recipe to your goals—choose lower oil for a lighter option, or pick a high-protein side if you want to build muscle or keep calories in check.
