Ingredients

- 1 medium red onion, cut into half-moon slices
- A few sprigs of fresh dill
- Salt and pepper to taste
- Juice from ½ lemon
- 2 tablespoons olive oil

- ¼ cup water
- Juice from an additional ½ lemon
- 1 teaspoon red pepper flakes
- Salt and pepper to taste
Preparing the Fish

Preheat the Oven
Preheat your oven to 400°F (200°C). Lining a baking sheet with parchment paper or foil will make cleanup a breeze later.
Season the Fish
Start with a clean branzino; it’s important to descale, wash, and pat it dry using clean paper towels. Remember, dry skin equals crisp skin! Make two slits on each side of the fish to help it cook evenly. Then, season both the inside and outside generously with salt, pepper, and garlic powder. Finally, drizzle some olive oil over the fish to keep it moist while roasting.
Add Fresh Aromatics
Stuff the cavity of the branzino with fresh dill, quartered tomatoes, and half-moon slices of red onion. This not only enhances flavor but also adds moisture while the fish bakes.
Roasting the Fish
Roast the Fish
Now, place the seasoned fish on the prepared baking sheet. Drizzle with fresh lemon juice to brighten the flavors. Roast in the oven for 20–25 minutes. You’ll know it’s done when the skin is golden and the flesh flakes easily with a fork.
Making the Sauce
Prepare the Sauce
While the fish is roasting, make the sauce. In a small saucepan, whisk together olive oil, white wine vinegar, water, lemon juice, red pepper flakes, salt, and pepper. Bring it to a boil over medium-high heat. The aroma will start to fill your kitchen!
Serving the Dish
Serve
Once the fish is out of the oven, it’s time to plate it. Drizzle the warm sauce over your beautiful roasted branzino. If you’d like, garnish with more fresh dill or lemon wedges for that extra pop!
Serving Suggestions
Pair this oven-roasted branzino with a side of roasted vegetables or a simple mixed green salad for a light, Mediterranean meal. Adding some crusty bread to soak up the flavorful sauce elevates the whole experience. And don’t forget to crack open a chilled glass of white wine!
Tips for Success
- Freshness is key—always aim for the freshest branzino for the best flavor.
- The slits in the fish are crucial! They allow the heat to penetrate and ensure even cooking.
- Feel free to experiment with additional herbs like parsley or basil for some variation.
Variations
- If branzino isn’t available, you can substitute it with another whole fish like snapper or sea bass.
- For a Mediterranean twist, add sliced lemons and olives to the fish’s cavity.
- Adjust the spice level by reducing or omitting the red pepper flakes to suit your taste.
Storage Tips
If you have any leftovers, store the roasted branzino in an airtight container in the refrigerator for up to 2 days. When you’re ready to enjoy it again, gently reheat it in the oven to preserve the texture.
Pairing Ideas
This branzino pairs delightfully with a refreshing couscous salad or lemon-infused quinoa. Grilled asparagus or garlic sautéed spinach also make excellent companions to complete your meal.
